Abstract

A method for cleaning an air conditioner. The method comprises: in response to a cleaning instruction, heating the surface temperature of a target heat exchanger to a first sterilization temperature for high-temperature sterilization; and after a high-temperature sterilization condition is satisfied, cooling the surface temperature of the target heat exchanger to a second sterilization temperature for rapid-cooling sterilization. By means of the method, bacteria breeding on a heat exchanger of an air conditioner can be killed by means of two successive processes, i.e. high-temperature sterilization and rapid-cooling sterilization, wherein high-temperature sterilization kills bacteria by using a relatively high temperature, and rapid-cooling sterilization kills bacteria by using a sudden change from hot to cold, i.e. from a high to low temperature. Microorganisms such as bacteria and mildew on the heat exchanger can be effectively reduced, thereby increasing the cleanliness of the interior of the air conditioner. Further disclosed is an air conditioner.

技术领域Technical field

本申请涉及智能家电技术领域，例如涉及一种用于空调器清洁的方法和空调器。This application relates to the technical field of smart home appliances, for example, to a method for cleaning an air conditioner and an air conditioner.

背景技术Background technique

目前，家居环境的洁净和健康性已被越来越多的用户所重视，空调器作为一种常见调节室内环境温湿度的空气设备，其洁净程度的高低能够极大的影响到室内环境的洁净性；从空调器长期的使用经验来看，空调器在循环输送室内空气的过程中，室内环境中的灰尘、杂质等会随着气流进入空调内部，导致空调器使用时间久了之后内部会积聚较多的污垢，针对这一情况，现有空调厂家也研发制造了很多具备自我清洁功能的空调产品，如具备喷淋冲洗换热器功能的空调器、具备蒸汽清洗换热器功能的空调器，等等。At present, the cleanliness and health of the home environment have been valued by more and more users. As a common air device that adjusts the temperature and humidity of the indoor environment, the level of cleanliness can greatly affect the cleanliness of the indoor environment. From the long-term use experience of the air conditioner, when the air conditioner circulates the indoor air, dust and impurities in the indoor environment will enter the inside of the air conditioner with the airflow, causing the air conditioner to accumulate after a long time of use A lot of dirt. In response to this situation, existing air conditioner manufacturers have also developed and manufactured many air-conditioning products with self-cleaning functions, such as air conditioners with spray and flushing heat exchanger functions, and air conditioners with steam cleaning heat exchanger functions. ,and many more.

空调器使用过程中不仅容易积聚较多的污垢，在夏季高温天气空调运行制冷模式时，由于会在换热器表面凝结较多的冷凝水，使得空调器内部也极易滋生细菌、霉菌等微生物；现有空调器的自我清洁功能往往只是针对灰尘油污等污垢，对于滋生的微生物的清洁效果不佳。When the air conditioner is in use, it is not only easy to accumulate more dirt. When the air conditioner is running in the cooling mode in high temperature weather in summer, because more condensed water will condense on the surface of the heat exchanger, it is easy to breed bacteria, mold and other microorganisms inside the air conditioner. ; The self-cleaning function of existing air conditioners is often only for dirt, such as dust, oil, and the like, and the cleaning effect on breeding microorganisms is not good.

图1是本公开实施例提供的一个用于空调器清洁的方法的示意图。Fig. 1 is a schematic diagram of a method for cleaning an air conditioner provided by an embodiment of the present disclosure.

结合图1所示，本公开实施例提供了一种用于空调器清洁的方法，该方法可用于杀灭空调器内部的细菌、霉菌等，降低滋生的微生物数量；在本实施例中，方法包括：As shown in FIG. 1, an embodiment of the present disclosure provides a method for cleaning an air conditioner, which can be used to kill bacteria, molds, etc. inside the air conditioner, and reduce the number of microorganisms that breed; in this embodiment, the method include:

S101、响应于清洁指令，将目标换热器的表面温度加热至第一灭菌温度，进行高温灭菌；S101. In response to the cleaning instruction, heat the surface temperature of the target heat exchanger to a first sterilization temperature to perform high-temperature sterilization;

在一些可选的实施例中，空调器的遥控器和控制面板上新增有“杀菌功能”或“灭菌功能”等的清洁选项，该清洁选项可用于触发运行本实施例中空调器清洁的方法流程；这样在用户对该清洁选项进行选定操作后，空调器生成相关的清洁指令，并响应执行。In some optional embodiments, a cleaning option such as "sterilization function" or "sterilization function" is added to the remote control and control panel of the air conditioner. This cleaning option can be used to trigger the operation of the air conditioner cleaning in this embodiment. The method flow; in this way, after the user selects the cleaning option, the air conditioner generates a related cleaning instruction and executes it in response.

在又一些可选的实施例中，空调器也可以通过检测触发、定时触发等方式生成相关的清洁指令，例如，空调器增设有微生物检测装置，可用于检测一种或多种特定类型微生物的含量，则在检测到的微生物的含量高于设定的含量阈值时，说明空调器滋生的微生物较多，空调器生成相关的清洁指令；又或者，空调器具有计时模块，可用于统计空调器累计运行的时长如制冷模式或者除湿模式的累计运行时长，这里随着空调器制冷模式或者除湿模式的累计运行时长的增加，空调器内部冷凝的冷凝水也就越多并且在该种湿润环境中微生物繁殖增长的数目也就越多，因此可以设定在空调器累计运行时长超过设定时长阈值时，空调器生成相关的清洁指令。In still other optional embodiments, the air conditioner can also generate related cleaning instructions through detection triggering, timing triggering, etc., for example, the air conditioner is equipped with a microorganism detection device that can be used to detect one or more specific types of microorganisms. Content, when the detected microorganism content is higher than the set content threshold, it means that the air conditioner breeds more microorganisms, and the air conditioner generates related cleaning instructions; or, the air conditioner has a timing module that can be used to count the air conditioner The cumulative operation time is like the cumulative operation time of the cooling mode or dehumidification mode. Here, as the cumulative operation time of the air conditioner cooling mode or dehumidification mode increases, the more condensed water inside the air conditioner will be condensed in this humid environment. The more the number of microorganisms multiplies and grows, so it can be set that when the cumulative operating time of the air conditioner exceeds the set time threshold, the air conditioner generates a related cleaning instruction.

在又一些可选的实施例中，空调器也可以与空调器原有清洁功能进行联动触发，如在用户选定原有清洁功能后，在执行该原有清洁功能限定的清洁流程之前生成清洁指令并执行本申请的清洁方法流程，或者在执行该原有清洁功能限定的清洁流程之后生成清洁指令并执行本申请的清洁方法流程；也即用户在选定一原有清洁功能之后，空调器是先后执行了两种不同的清洁流程，通过双重清洁的方式有效保障了空调器内部的洁净度。In still other optional embodiments, the air conditioner can also be triggered in conjunction with the original cleaning function of the air conditioner. For example, after the user selects the original cleaning function, the original cleaning function is executed before the cleaning process defined by the original cleaning function is generated. Instruct and execute the cleaning method process of this application, or generate a cleaning instruction and execute the cleaning method process of this application after executing the cleaning process defined by the original cleaning function; that is, after the user selects an original cleaning function, the air conditioner Two different cleaning processes have been implemented successively, and the cleanliness of the inside of the air conditioner is effectively guaranteed through the double cleaning method.

例如，空调器原有清洁功能为喷淋清洗功能，该喷淋清洗功能是将水喷淋至空调器的换热器上，以通过流水冲刷的方式清洁换热器，则一种可选的实施方式是本申请的清洁方法流程是在执行喷淋清洗功能之前运行，也即在用户选定喷淋清洗功能之后，先控制执行本申请清洁方法流程杀灭细菌等微生物，之后在执行喷淋清洗功能，这样流水不仅可以冲洗掉灰尘、油污等污垢，同时也可以将换热器上被杀灭的微生物一并冲刷掉。For example, the original cleaning function of an air conditioner is a spray cleaning function. The spray cleaning function is to spray water onto the heat exchanger of the air conditioner and clean the heat exchanger by flushing with running water. This is an optional The implementation is that the cleaning method process of this application runs before the spray cleaning function is executed, that is, after the user selects the spray cleaning function, the cleaning method process of this application is first controlled to kill bacteria and other microorganisms, and then the spray cleaning function is executed. The cleaning function, so that the running water can not only wash away dust, oil and other dirt, but also wash away the killed microorganisms on the heat exchanger.

在本实施例中，主要是以室内换热器为目标换热器举例说明，在执行步骤S101时，空调器调整***内冷媒流向与制热模式的冷媒流向一致，使压缩机排出的高温冷媒先流经室内换热器，以利用高温冷媒的热量加热室内换热器,将室内换热器的表面温度加热至第一灭菌温度，进行高温灭菌。In this embodiment, the indoor heat exchanger is mainly used as an example of the target heat exchanger. When step S101 is performed, the air conditioner adjusts the refrigerant flow direction in the system to be consistent with the refrigerant flow direction of the heating mode, so that the high temperature refrigerant discharged from the compressor It first flows through the indoor heat exchanger to use the heat of the high-temperature refrigerant to heat the indoor heat exchanger, and heat the surface temperature of the indoor heat exchanger to the first sterilization temperature for high-temperature sterilization.

可选的，第一灭菌温度的取值范围为大于或等于60℃。在室内换热器的表面处于该温度状况下，室内换热器表面滋生的细菌、霉菌等微生物受热会逐渐死亡，从而达到杀菌灭菌的效果。在本实施例中，第一灭菌温度为65℃。Optionally, the value range of the first sterilization temperature is greater than or equal to 60°C. When the surface of the indoor heat exchanger is at this temperature, the bacteria, molds and other microorganisms that grow on the surface of the indoor heat exchanger will gradually die when heated, so as to achieve the effect of sterilization. In this embodiment, the first sterilization temperature is 65°C.

S102、在满足高温灭菌条件后，将目标换热器的表面温度降低至第二灭菌温度，进行速冷灭菌。S102: After satisfying the high temperature sterilization condition, reduce the surface temperature of the target heat exchanger to the second sterilization temperature, and perform rapid cooling sterilization.

在一些可选的实施例中，高温灭菌条件包括：In some optional embodiments, the high temperature sterilization conditions include:

T _e≥T1 _灭菌且t _高温≥t1； T _e ≥ T1 _{sterilization} and t _{high temperature} ≥ t1;

其中，T _e为室内换热器的盘管温度，本公开实施例中是以室内换热器的盘管位置的温度作为衡量室内换热器的表面温度的参数，则在盘管温度大于第一灭菌温度的情况下，可视为室内换热器的表面温度也大于该灭菌温度；T1 _灭菌为第一灭菌温度，t _高温为高温灭菌的持续时长，t1为高温灭菌时长阈值。 Among them, T _e is the coil temperature of the indoor heat exchanger. In the embodiments of the present disclosure, the temperature of the coil position of the indoor heat exchanger is used as a parameter to measure the surface temperature of the indoor heat exchanger. In the case of a sterilization temperature, it can be regarded that the surface temperature of the indoor heat exchanger is also greater than the sterilization temperature; T1 _{sterilization} is the first sterilization temperature, t _{high temperature} is the duration of high temperature sterilization, and t1 is high temperature sterilization Duration threshold.

可选的，t1的取值范围是大于等于30分钟。根据试验证明，当室内换热器的表面温度大于等于第一灭菌温度的持续时长大于等于30分钟时，实际灭菌效果较好，本实施例中t1为35分钟。Optionally, the value range of t1 is greater than or equal to 30 minutes. According to test results, when the surface temperature of the indoor heat exchanger is greater than or equal to the first sterilization temperature and the duration is greater than or equal to 30 minutes, the actual sterilization effect is better. In this embodiment, t1 is 35 minutes.

这里，空调器在室内换热器的盘管位置设置有一温度传感器，该温度传感器可用于检测室内换热器的盘管的实时温度；同时，空调器还设置有一用于统计室内换热器进行高温灭菌的持续时长的计时模块，该计时模块在执行步骤S101过程中的室内换热器的盘管温度大于等于第一灭菌温度时启动计时。这里，在确定满足高温灭菌条件后，计时模块清零。Here, the air conditioner is provided with a temperature sensor at the coil position of the indoor heat exchanger, and the temperature sensor can be used to detect the real-time temperature of the coil of the indoor heat exchanger; at the same time, the air conditioner is also provided with a temperature sensor for statistics of the indoor heat exchanger. A timing module for the duration of high temperature sterilization, which starts timing when the coil temperature of the indoor heat exchanger in the process of performing step S101 is greater than or equal to the first sterilization temperature. Here, after determining that the high temperature sterilization conditions are met, the timing module is cleared.

在本实施例中，若不满足高温灭菌条件，则继续保持运行步骤S101的高温灭菌流程。In this embodiment, if the high-temperature sterilization conditions are not met, the high-temperature sterilization process of running step S101 is continued to be maintained.

在一些可选的实施方式中，在执行步骤S102的速冷灭菌流程时，空调器调整***内冷媒流向与制冷模式的冷媒流向一致，使压缩机排出的高温冷媒先流经室外换热器，之后节流降压后的低温冷媒输入室内换热器，以利用低温冷媒的“冷量”吸收室内换热器的热量、对室内换热器进行降温,将室内换热器的表面温度降低至第二灭菌温度，进行速冷灭菌。In some alternative embodiments, when the rapid cooling sterilization process of step S102 is performed, the air conditioner adjusts the flow direction of the refrigerant in the system to be consistent with the flow direction of the refrigerant in the cooling mode, so that the high-temperature refrigerant discharged from the compressor flows through the outdoor heat exchanger first Then, the low-temperature refrigerant after throttling and depressurization is input into the indoor heat exchanger to use the "cold capacity" of the low-temperature refrigerant to absorb the heat of the indoor heat exchanger, cool the indoor heat exchanger, and reduce the surface temperature of the indoor heat exchanger To the second sterilization temperature, perform quick-cooling sterilization.

可选的，第二灭菌温度的取值范围为小于等于5℃。这里，由于前一高温灭菌阶段室内换热器处于温度较高的状态，而后一速冷灭菌阶段室内换热器切换至温度较低的状态，室内换热器的表面温度发生了较大幅度的冷热变化，实验证明该温度从高到低的冷热急剧变化过程也能够有效对微生物进行灭活,从而实现强化灭菌的效果。在本实施例中，第二灭菌温度为5℃。Optionally, the value range of the second sterilization temperature is less than or equal to 5°C. Here, since the indoor heat exchanger in the previous high temperature sterilization stage is at a higher temperature, and the indoor heat exchanger in the latter rapid cooling sterilization stage switches to a lower temperature state, the surface temperature of the indoor heat exchanger is relatively high. Experiments show that the rapid change of temperature from high to low can also effectively inactivate microorganisms, thereby achieving the effect of enhanced sterilization. In this embodiment, the second sterilization temperature is 5°C.

在一些可选的实施例中，在执行步骤S102后，若满足速冷灭菌条件，则控制退出速冷灭菌。In some optional embodiments, after step S102 is performed, if the rapid-cooling sterilization condition is satisfied, the rapid-cooling sterilization is controlled to exit.

可选的，速冷灭菌条件包括：Optionally, the rapid cold sterilization conditions include:

T _e≤T2 _灭菌且t _低温≥t2； T _e ≤ T2 _{sterilization} and t _{low temperature} ≥ t2;

其中，T2 _灭菌为第二灭菌温度，t _速冷为速冷灭菌的持续时长，t2为速冷灭菌时长阈值。 Among them, T2 _{sterilization} is the second sterilization temperature, t _{rapid cooling} is the duration of rapid cooling sterilization, and t2 is the rapid cooling sterilization duration threshold.

可选的，t2的取值范围是大于等于10分钟。本实施例中t2为10分钟。Optionally, the value range of t2 is greater than or equal to 10 minutes. In this embodiment, t2 is 10 minutes.

这里，计时模块还可用于统计室内换热器进行速冷灭菌的持续时长，该计时模块在执行步骤S102过程中的室内换热器的盘管温度小于等于第二灭菌温度时启动计时。这里，在确定满足速冷灭菌条件后，计时器清零。Here, the timing module can also be used to count the duration of the rapid cooling sterilization of the indoor heat exchanger. The timing module starts timing when the coil temperature of the indoor heat exchanger is less than or equal to the second sterilization temperature during the execution of step S102. Here, the timer is cleared after confirming that the conditions for rapid cooling sterilization are met.

在本实施例中，若不满足速冷灭菌条件，则继续保持运行步骤S102的速冷灭菌流程。In this embodiment, if the rapid cooling sterilization condition is not satisfied, the rapid cooling sterilization process of step S102 is continued to be maintained.

在本实施例中，为保证高温灭菌和速冷灭菌两个阶段的灭菌效果，主要是通过控制室内风机、导风板、室外风机、节流装置、压缩机和/或四通阀等部件的工作参数实现，下面结合图2对各个阶段的参数控制分别进行示例性说明，其中图2的纵坐标为被控的各个部件的参数幅度变化，横坐标为时间。In this embodiment, in order to ensure the sterilization effect of the two stages of high temperature sterilization and rapid cooling sterilization, it is mainly through controlling the indoor fan, air deflector, outdoor fan, throttling device, compressor and/or four-way valve The working parameters of other components are realized, and the parameter control of each stage will be exemplified below with reference to Fig. 2, where the ordinate in Fig. 2 is the parameter amplitude change of each component to be controlled, and the abscissa is time.

(一)高温灭菌阶段(1) High temperature sterilization stage

室内风机在高温灭菌阶段中的控制过程分为前后两个阶段，前一阶段室内风机为停机状态，此时压缩机排出的高温冷媒开始输入室内换热器，为使室内换热器尽快升温、减少热量向室内环境的散失，因此将室内风机控制为停机状态；后一阶段室内风机为低转速状态(低档风速)，经过前一阶段后室内换热器的表面温度已接近或者达到第一灭菌温度，则此时通过控制室内风机低速运转，可以使热量在室内机内部传导，提升室内机其它部位的温度，以实现对空调机其它部位进行高温灭菌的效果。The control process of the indoor fan in the high-temperature sterilization stage is divided into two stages. In the previous stage, the indoor fan is in a shutdown state. At this time, the high-temperature refrigerant discharged from the compressor starts to be input to the indoor heat exchanger, in order to make the indoor heat exchanger heat up as soon as possible , Reduce the loss of heat to the indoor environment, so the indoor fan is controlled to stop; the indoor fan is in a low-speed state (low wind speed) in the latter stage, and the surface temperature of the indoor heat exchanger after the previous stage is close to or reaches the first stage. Sterilization temperature, at this time, by controlling the indoor fan to run at a low speed, heat can be conducted inside the indoor unit, and the temperature of other parts of the indoor unit can be raised, so as to achieve the effect of high-temperature sterilization of other parts of the air conditioner.

可选的，室内风机的前后两个阶段可以采用固定时长设置，例如高温灭菌阶段的时长为35分钟，则前一阶段的时长设定为5分钟，后一阶段的时长设定为30分钟；这样，通过统计每一阶段的持续时长，在满足时长要求时控制对室内风机的状态切换。Optionally, the front and back stages of the indoor fan can be set with a fixed duration. For example, if the duration of the high temperature sterilization stage is 35 minutes, the duration of the previous stage is set to 5 minutes, and the duration of the latter stage is set to 30 minutes. ; In this way, by counting the duration of each stage, the state switching of the indoor fan can be controlled when the time requirement is met.

在一些可选的实施例中，室内风机的前后两个阶段的切换可以根据盘管温度确定。In some optional embodiments, the switching between the front and back stages of the indoor fan may be determined according to the temperature of the coil.

在空调器开始执行步骤S101的高温灭菌阶段时，实时通过温度传感器检测室内换热器的盘管温度，在盘管温度未达到第一灭菌温度之前，控制室内风机为停机状态，此为前一阶段，室内风机始终为停机状态；而在盘管温度达到第一灭菌温度后，进行阶段切换，室内风机切换为低转速状态。相比于前一根据固定时长进行控制的实施方式，本实施例能够更加精确的实现室内风机两个阶段的状态切换，保证室内换热器的升温速率以及室内机其它部分的灭菌效果。When the air conditioner starts to perform the high temperature sterilization phase of step S101, the temperature sensor detects the coil temperature of the indoor heat exchanger in real time. Before the coil temperature reaches the first sterilization temperature, the indoor fan is controlled to be in a shutdown state, which is In the previous stage, the indoor fan is always in a shutdown state; and after the coil temperature reaches the first sterilization temperature, the stage is switched, and the indoor fan is switched to a low-speed state. Compared with the previous implementation of controlling based on a fixed duration, this embodiment can more accurately realize the two-stage state switching of the indoor fan, and ensure the heating rate of the indoor heat exchanger and the sterilization effect of other parts of the indoor unit.

在又一些可选的实施例中，室内风机的前后两个阶段的切换可以根据压缩机的初始频率确定。这里，压缩机的初始频率能够影响到其排出的冷媒温度，进而影响到对室内换热器的升温速度和室内机进行状态切换所需的时长。In still other alternative embodiments, the switching between the front and back stages of the indoor fan may be determined according to the initial frequency of the compressor. Here, the initial frequency of the compressor can affect the temperature of the refrigerant discharged from it, which in turn affects the heating rate of the indoor heat exchanger and the time required for state switching of the indoor unit.

示例性的，在空调器执行步骤S101的高温灭菌阶段前，获取压缩机的初始频率，在初始频率大于设定频率阈值时，第一阶段的时长为第一时长；而在初始频率小于或等于设定频率阈值时，第一阶段的时长为第二时长，其中，第二时长大于第一时长。也即压缩机的初始频率越大，排出的冷媒温度越高，则室内换热器的表面温度达到第一灭菌温度所需的时间就越短。因此本实施例是根据压缩机的初始频率控制室内风机的状态切换，同样也可以达到精确控制、保障升温速率的作用。Exemplarily, before the air conditioner performs the high-temperature sterilization stage of step S101, the initial frequency of the compressor is obtained. When the initial frequency is greater than the set frequency threshold, the duration of the first stage is the first duration; and when the initial frequency is less than or When it is equal to the set frequency threshold, the duration of the first stage is the second duration, where the second duration is greater than the first duration. That is, the higher the initial frequency of the compressor and the higher the temperature of the discharged refrigerant, the shorter the time required for the surface temperature of the indoor heat exchanger to reach the first sterilization temperature. Therefore, in this embodiment, the state switching of the indoor fan is controlled according to the initial frequency of the compressor, which can also achieve precise control and guarantee the heating rate.

在一些可选的实施例中，在高温灭菌阶段，室内机的导板为关闭状态或者微开状态，从而减少室内机内部的热量从出风口向室内环境的逸散。可选的，在制热工况，可以控制室内机的导板以稍大的角度开启，使高温灭菌过程中的部分冷媒热量仍能够持续的输送到室内环境中，避免清洁过程中室内环境温度降低对用户造成的不适影响。In some optional embodiments, during the high-temperature sterilization stage, the guide plate of the indoor unit is in a closed state or a slightly opened state, so as to reduce the dissipation of heat inside the indoor unit from the air outlet to the indoor environment. Optionally, in heating conditions, the guide plate of the indoor unit can be controlled to open at a slightly larger angle, so that part of the refrigerant heat during the high-temperature sterilization process can still be continuously transported to the indoor environment, avoiding the indoor environment temperature during the cleaning process Reduce the discomfort to users.

高温灭菌阶段的参数包括根据室外环境温度获取的第一高温灭菌参数，其中第一高温灭菌参数包括室外风机的第一外机转速、节流装置的第一开度。The parameters of the high temperature sterilization stage include the first high temperature sterilization parameters obtained according to the outdoor ambient temperature, where the first high temperature sterilization parameters include the first outdoor machine speed of the outdoor fan and the first opening degree of the throttling device.

对于高温灭菌阶段的室外风机控制，室外风机对应的室外换热器处于吸热状态，室外环境温度与室外换热器之间的换热温差的高低能够影响到室外换热器的吸热效率，进而影响到对室内换热器的加热升温效果；这里，室外环境温度与室外风机为负相关关系，即室外环境温度越低，则其与室外换热器之间的换热温差就就越大，为保证吸热效果所需的换热风量也就越大。因此，本实施中根据室外环境温度的高低调整室外风机的转速，从而增强室外换热器的吸热效率，进而可以增加高温灭菌效果。For the outdoor fan control in the high temperature sterilization stage, the outdoor heat exchanger corresponding to the outdoor fan is in a heat-absorbing state, and the heat exchange temperature difference between the outdoor ambient temperature and the outdoor heat exchanger can affect the heat absorption efficiency of the outdoor heat exchanger , Which in turn affects the heating effect of the indoor heat exchanger; here, the outdoor ambient temperature has a negative correlation with the outdoor fan, that is, the lower the outdoor ambient temperature, the greater the heat exchange temperature difference between it and the outdoor heat exchanger Larger, the greater the amount of heat exchange air required to ensure the heat absorption effect. Therefore, in this implementation, the rotation speed of the outdoor fan is adjusted according to the outdoor environment temperature, so as to enhance the heat absorption efficiency of the outdoor heat exchanger, thereby increasing the high-temperature sterilization effect.

可选的，空调器预设有室外环境温度与外机转速的第一关联关系，该第一关联关系包括室外环境温度与外机转速的一一对应关系。因此通过查找该关联关系就能够获取与当前的室外环境温度对应的外机转速，进而控制室外风机以该外机转速作为第一外机转速运行。Optionally, the air conditioner is preset with a first association relationship between the outdoor ambient temperature and the rotation speed of the outdoor machine, and the first association relationship includes a one-to-one correspondence between the outdoor ambient temperature and the rotation speed of the outdoor machine. Therefore, the rotation speed of the outdoor machine corresponding to the current outdoor ambient temperature can be obtained by searching for the correlation, and then the outdoor fan can be controlled to run at the rotation speed of the outdoor machine as the first outdoor machine speed.

在又一些可选的实施例中，压缩机的频率也能够影响室外换热器的吸热效率。这里，压缩机的运行频率越高，排出的冷媒量越多，因而流入室外换热器进行换热的冷媒量也越大。因此在本实施例中是以室外环境温度和压缩机的频率共同用于确定室外风机在高温灭菌阶段的温度，表1中示出的一种可选的室外环境温度Tao和压缩机的频率f与室外风机的外机转速之间的对应关系：In still other alternative embodiments, the frequency of the compressor can also affect the heat absorption efficiency of the outdoor heat exchanger. Here, the higher the operating frequency of the compressor, the greater the amount of refrigerant discharged, and therefore the greater the amount of refrigerant flowing into the outdoor heat exchanger for heat exchange. Therefore, in this embodiment, the outdoor ambient temperature and the compressor frequency are used together to determine the temperature of the outdoor fan in the high-temperature sterilization stage. Table 1 shows an optional outdoor ambient temperature Tao and the compressor frequency Correspondence between f and the rotation speed of the outdoor fan:

表1Table 1

在本实施例中，设定室外风机的转速档位分为7个级别，转速依次增大；表1中示出的就不同室外环境温度和频率组合所各自对应的室外风机的转速档位，在本实施例中，高温灭菌阶段的室外风机的转速控制可以通过查找上表的方式确定。In this embodiment, the rotation speed gears of the outdoor fan are set into 7 levels, and the rotation speed increases in sequence; Table 1 shows the rotation speed gears of the outdoor fan corresponding to different outdoor ambient temperature and frequency combinations. In this embodiment, the rotation speed control of the outdoor fan in the high-temperature sterilization stage can be determined by looking up the above table.

在一些可选的实施例中，由于室外换热器处于吸热状态，因此室外换热器自身也是处于较低的温度状态，若室外环境温度也是较低的温度状况，则室外换热器容易出现结霜的现象，例如在冬季制热工况运行本申请清洁方法流程时，室外环境温度很低，室外换热器在高温灭菌阶段就容易逐渐凝结冰霜，影响室外换热器从外界环境的吸热效率。因此本申请对于高温灭菌阶段的节流装置的控制，主要是根据室外环境的温度状况调节节流装置的开度；例如，本申请在室外环境温度较低时以较高的开度调节节流装置，这样从室内换热器流入室外换热器的冷媒也能保持较高的温度，以利用残留的冷媒热量以延缓室外换热器的结霜速度；而在室外环境屋内的较低时则以较低的开度调节节流装置，以使节流后的冷媒温度和压力更低，从而提高冷媒与外界环境的热交换效率。In some optional embodiments, since the outdoor heat exchanger is in a heat-absorbing state, the outdoor heat exchanger itself is also in a lower temperature state. If the outdoor ambient temperature is also a lower temperature condition, the outdoor heat exchanger is easy to Frosting occurs. For example, when the cleaning method process of this application is run in the heating condition in winter, the outdoor environment temperature is very low, and the outdoor heat exchanger is prone to gradually condense frost during the high-temperature sterilization stage, which affects the outdoor heat exchanger from the external environment. The heat absorption efficiency. Therefore, the control of the throttling device in the high-temperature sterilization stage in this application is mainly to adjust the opening degree of the throttling device according to the temperature condition of the outdoor environment; In this way, the refrigerant flowing from the indoor heat exchanger into the outdoor heat exchanger can also maintain a higher temperature, so as to use the remaining refrigerant heat to delay the frosting speed of the outdoor heat exchanger; The throttling device is adjusted with a lower opening degree, so that the temperature and pressure of the refrigerant after throttling are lower, thereby improving the heat exchange efficiency between the refrigerant and the external environment.

可选的，空调器预设有室外环境温度与节流装置的开度的第一关联关系，该第一关联关系包括室外环境温度与开度的一一对应关系。因此通过查找该关联关系就能够获取与当前的室外环境温度对应的开度，进而控制节流装置以该开度作为第一开度开启。表2中示出了一个可选的实施例中室外环境温度与节流装置的开度之间的关联关系。Optionally, the air conditioner is preset with a first correlation relationship between the outdoor ambient temperature and the opening degree of the throttling device, and the first correlation relationship includes a one-to-one correspondence between the outdoor ambient temperature and the opening degree. Therefore, the opening degree corresponding to the current outdoor ambient temperature can be obtained by searching the association relationship, and then the throttle device can be controlled to turn on the opening degree as the first opening degree. Table 2 shows the correlation between the outdoor ambient temperature and the opening degree of the throttling device in an optional embodiment.

表2Table 2

室外环温Outdoor ambient temperature	Tao≥16℃Tao≥16℃	5℃≤Tao<16℃5℃≤Tao<16℃	Tao<5℃Tao<5℃
高温灭菌阶段开度Opening degree of high temperature sterilization stage	220220	240240	260260

因此在本实施例中，高温灭菌阶段的节流装置的开度控制可以通过查找上表的方式确定。Therefore, in this embodiment, the opening control of the throttling device in the high-temperature sterilization stage can be determined by looking up the above table.

上述多个实施例中，空调器的室外机设置有温度传感器，该温度传感器可用于检测得到用于获取第一高温灭菌参数的室外环境温度。In the foregoing multiple embodiments, the outdoor unit of the air conditioner is provided with a temperature sensor, and the temperature sensor can be used to detect the outdoor ambient temperature used to obtain the first high temperature sterilization parameter.

在本实施例中，高温灭菌阶段还包括根据室内盘管温度获取第二高温灭菌参数,第二高温灭菌参数包括压缩机的频率。In this embodiment, the high-temperature sterilization stage further includes acquiring a second high-temperature sterilization parameter according to the temperature of the indoor coil, and the second high-temperature sterilization parameter includes the frequency of the compressor.

在一些可选的实施例中，高温灭菌阶段的关键之一是室内换热器能够达到并维持在第一灭菌温度，由于压缩机排出的高温冷媒是先流向室内换热器，因此对于高温灭菌阶段的压缩机的控制主要是根据室内换热器的盘管温度确定。In some alternative embodiments, one of the keys to the high-temperature sterilization stage is that the indoor heat exchanger can reach and maintain the first sterilization temperature. Since the high-temperature refrigerant discharged from the compressor flows to the indoor heat exchanger first, The control of the compressor in the high-temperature sterilization stage is mainly determined according to the temperature of the coil of the indoor heat exchanger.

可选的，在室内换热器的盘管温度小于第一灭菌温度时，控制压缩机以数值较大的第一频率运行，以增加排入室内换热器的高温冷媒量和冷媒温度，加快室内换热器升温至第一灭菌温度的速度；而在室内换热器的盘管温度大于或等于第一灭菌温度时，控制压缩机以数值小于第一频率的第二频率运行，在使室内换热器维持在第一灭菌温度的情况下，也可以避免室内换热器继续升温导致触发高温保护的问题，并能够减少压缩机的运行功耗，节能环保。Optionally, when the coil temperature of the indoor heat exchanger is lower than the first sterilization temperature, the compressor is controlled to run at a first frequency with a larger value to increase the amount of high-temperature refrigerant discharged into the indoor heat exchanger and the temperature of the refrigerant, Speed up the indoor heat exchanger to heat up to the first sterilization temperature; and when the coil temperature of the indoor heat exchanger is greater than or equal to the first sterilization temperature, control the compressor to run at a second frequency that is less than the first frequency. In the case that the indoor heat exchanger is maintained at the first sterilization temperature, the problem of triggering high temperature protection due to the continuous heating of the indoor heat exchanger can also be avoided, and the operating power consumption of the compressor can be reduced, which is energy-saving and environmentally friendly.

这里，高温灭菌阶段还包括根据室内盘管温度获取、在目标换热器的表面温度大于或等于设定安全温度阈值时压缩机的降频速率，设定安全温度阈值大于第一灭菌温度。这里，安全温度阈值为换热器处于安全温度范围内的临界值，当换热器的当前温度超出该安全温度范围时，则会危害空调器的运行，容易出现故障、引发火灾等情况，本实施例中通过比较室内换热器的室内盘管温度与设定安全温度阈值，并根据比较结果控制压缩机进行降频，以减少输入换热器的冷媒量和冷媒温度，使换热器能够重新逐渐降温至安全温度范围内。Here, the high-temperature sterilization stage also includes the frequency reduction rate of the compressor when the surface temperature of the target heat exchanger is greater than or equal to the set safe temperature threshold obtained according to the indoor coil temperature, and the set safe temperature threshold is greater than the first sterilization temperature . Here, the safe temperature threshold is the critical value at which the heat exchanger is within the safe temperature range. When the current temperature of the heat exchanger exceeds the safe temperature range, it will endanger the operation of the air conditioner, prone to malfunctions, fires, etc. In the embodiment, the indoor coil temperature of the indoor heat exchanger is compared with the set safe temperature threshold, and the compressor is controlled to reduce the frequency according to the comparison result to reduce the amount of refrigerant input to the heat exchanger and the temperature of the refrigerant, so that the heat exchanger can Gradually decrease the temperature again to within the safe temperature range.

空调器预设有室内盘管温度与降频速率的第二关联关系，预设的第二关联关系包括室内盘管温度与降频速率的对应关系。在一个可选的实施方式中，本申请将设定安全温度阈值分为三个阈值档位(第一阈值、第二阈值和第三阈值)，三个阈值档位的温度数值逐渐增大；其中，在室内盘管温度小于等于第一阈值时，换热器目前运行状态正常，则保持当前压缩机的运行频率；而在室内盘管温度大于第一阈值、小于等于第二阈值时，则换热器存在异常，此时压缩机以数值较小的第一降频速率进行降频；而在室内盘管温度大于第二阈值、小于等于第三阈值时，则换热器异常情况较严重，此时压缩机以数值大于第一降频速率的第二降频速率进行降频，以加快对换热器的降温操作，加快热量的减少输出操作；在室内盘管温度大于第三阈值时，则换热器异常情况非常严重，此时控制压缩机停机，停止向换热器输入冷媒。The air conditioner is preset with a second correlation between the indoor coil temperature and the frequency reduction rate, and the preset second correlation includes the corresponding relationship between the indoor coil temperature and the frequency reduction rate. In an optional implementation manner, the present application divides the set safe temperature threshold into three threshold gears (a first threshold, a second threshold, and a third threshold), and the temperature values of the three threshold gears gradually increase; Among them, when the indoor coil temperature is less than or equal to the first threshold, the current operating state of the heat exchanger is normal, and the current compressor operating frequency is maintained; and when the indoor coil temperature is greater than the first threshold and less than or equal to the second threshold, then There is an abnormality in the heat exchanger. At this time, the compressor will decrease the frequency at the first decrease rate with a smaller value. When the indoor coil temperature is greater than the second threshold and less than or equal to the third threshold, the abnormality of the heat exchanger is more serious. , At this time, the compressor performs frequency reduction at a second frequency reduction rate greater than the first frequency reduction rate to speed up the cooling operation of the heat exchanger and speed up the heat output reduction operation; when the indoor coil temperature is greater than the third threshold , The abnormal condition of the heat exchanger is very serious. At this time, the compressor is controlled to stop and the refrigerant input to the heat exchanger is stopped.

在一些可选的实施例中，在高温灭菌阶段，四通阀切换并保持使冷媒沿与制热模式一致的流向流动的阀位。In some optional embodiments, during the high-temperature sterilization stage, the four-way valve switches and maintains a valve position that allows the refrigerant to flow in a direction consistent with the heating mode.

(二)速冷灭菌阶段(2) Rapid cold sterilization stage

室内风机在速冷灭菌阶段以高于高温灭菌阶段的转速运行，如中档转速、高档转速等等；在速冷灭菌阶段冷媒沿与制冷模式一致的流向流动，输入室内换热器的冷媒为低温冷媒，由于前一高温灭菌阶段使室内机内部整体处于较高的温度状态，因此为了能在短时间内降低室内换热器的温度、达到使室内换热器温度发生冷热急剧变化的效果，本申请提高室内风机的转速，以加快室内机的内部热空气与低温冷媒之间的热交换速度，同时也可以加快热空气向室内环境的排出，使室内换热器的能够降温至第二灭菌温度以下。The indoor fan runs at a higher speed than the high-temperature sterilization stage during the rapid-cooling sterilization stage, such as mid-range speed, high-end speed, etc.; during the rapid-cooling sterilization stage, the refrigerant flows in the same direction as the cooling mode and is input to the indoor heat exchanger. The refrigerant is a low-temperature refrigerant. Because the entire indoor unit is at a higher temperature during the previous high-temperature sterilization stage, in order to reduce the temperature of the indoor heat exchanger in a short period of time, the temperature of the indoor heat exchanger can be heated rapidly. The effect of the change is that this application increases the speed of the indoor fan to speed up the heat exchange speed between the hot air inside the indoor unit and the low-temperature refrigerant, and also speeds up the discharge of hot air to the indoor environment, so that the indoor heat exchanger can cool down To below the second sterilization temperature.

在图中未示出的一些实施例中，速冷灭菌阶段的室内风机的转速控制也可以根据室内盘管温度确定。In some embodiments not shown in the figure, the speed control of the indoor fan in the rapid cooling sterilization stage may also be determined according to the temperature of the indoor coil.

示例性的，在空调器开始执行步骤S102的速冷灭菌阶段时，利用实时温度传感器检测室内换热器的盘管温度，在盘管温度未降低到第二灭菌温度之前，控制室内风机为中档转速状态，而在盘管温度降低到第二灭菌温度后，室内风机切换为低转速状态或者停机状态。该种控制方式可以提高室内换热器在速冷灭菌阶段的降温速冷，进而提升强化灭菌效果。Exemplarily, when the air conditioner starts to perform the rapid cooling sterilization phase of step S102, the real-time temperature sensor is used to detect the coil temperature of the indoor heat exchanger, and the indoor fan is controlled before the coil temperature is lowered to the second sterilization temperature It is in the mid-range speed state, and after the coil temperature drops to the second sterilization temperature, the indoor fan is switched to a low speed state or a shutdown state. This control method can increase the temperature and speed of the indoor heat exchanger during the rapid cooling and sterilization stage, thereby enhancing the enhanced sterilization effect.

在一些可选的实施例中，在速冷灭菌阶段，室内机的导板为微开状态，从而加快室内机的热空气的排出，提高降温速冷。同时，根据当前制冷制热工况的不同，可以进一步对室内机的导板的开启角度进行调整，如在制热工况，可以控制室内机的导板以稍大的角度开启，使热空气能够被较多的排入室内环境中，提高了对高温灭菌阶段的余热的利用率；而在制冷工况，则控制室内机的导板向上送风，以避免出现热风直吹用户的情况，提高用户的使用体验。In some optional embodiments, during the rapid-cooling sterilization stage, the guide plate of the indoor unit is slightly opened, thereby speeding up the discharge of hot air from the indoor unit and improving the cooling and rapid cooling. At the same time, according to the current cooling and heating working conditions, the opening angle of the guide plate of the indoor unit can be further adjusted. For example, in the heating working condition, the guide plate of the indoor unit can be controlled to open at a slightly larger angle, so that the hot air can be More discharge into the indoor environment, which improves the utilization of the waste heat in the high temperature sterilization stage; while in the refrigeration mode, the guide plate of the indoor unit is controlled to send air upwards to avoid the hot air blowing directly on the user, and improve the user Experience.

速冷灭菌阶段包括根据室外环境温度获取的第一速冷灭菌参数,其中第一速冷灭菌参数包括室外风机的第二外机转速和压缩机的第一频率。The rapid cooling sterilization stage includes a first rapid cooling sterilization parameter obtained according to the outdoor ambient temperature, wherein the first rapid cooling sterilization parameter includes the second outdoor machine speed of the outdoor fan and the first frequency of the compressor.

对于速冷灭菌阶段的室外风机控制，室外风机对应的室外换热器处于放热状态，室外环境温度与室外换热器之间的换热温差的高低能够影响到室外换热器的放热效率，进而影响到对室内换热器的降温速冷效果；这里，室外环境温度与室外风机为正相关关系，即室外环境温度越高，则其与室外换热器之间的换热温差就就越小，为保证吸热效果所需的换热风量也就越大。因此，本实施中根据室外环境温度的高低调整室外风机的转速，从而增强室外换热器的散热效率，进而可以增加速冷灭菌效果。For the control of the outdoor fan in the rapid cooling sterilization stage, the outdoor heat exchanger corresponding to the outdoor fan is in a state of heat release, and the heat exchange temperature difference between the outdoor ambient temperature and the outdoor heat exchanger can affect the heat release efficiency of the outdoor heat exchanger , Which in turn affects the cooling and rapid cooling effect of the indoor heat exchanger; here, the outdoor ambient temperature is positively correlated with the outdoor fan, that is, the higher the outdoor ambient temperature, the higher the heat exchange temperature difference between it and the outdoor heat exchanger. The smaller the amount, the greater the amount of heat exchange air required to ensure the heat absorption effect. Therefore, in the present embodiment, the rotation speed of the outdoor fan is adjusted according to the outdoor environment temperature, thereby enhancing the heat dissipation efficiency of the outdoor heat exchanger, thereby increasing the rapid cooling sterilization effect.

可选的，空调器预设有室外环境温度与外机转速的第三关联关系，该第一关联关系包括室外环境温度与外机转速的一一对应关系。因此通过查找该关联关系就能够获取与当前的室外环境温度对应的外机转速，进而控制室外风机以该外机转速作为第二外机转速运行。Optionally, the air conditioner is preset with a third correlation between the outdoor ambient temperature and the rotation speed of the outdoor machine, and the first correlation includes a one-to-one correspondence between the outdoor ambient temperature and the rotation speed of the outdoor machine. Therefore, the rotation speed of the outdoor machine corresponding to the current outdoor ambient temperature can be obtained by searching for the correlation, and then the outdoor fan can be controlled to operate at the rotation speed of the outdoor machine as the second outdoor machine speed.

在又一些可选的实施例中，压缩机的频率也能够影响室外换热器的放热效率。这里，压缩机的运行频率越高，排出的冷媒量越多，因而流入室外换热器进行换热的冷媒量也越大。因此在本实施例中是以室外环境温度和压缩机的频率共同用于确定室外风机在速冷灭菌阶段的温度，表3中示出的一种可选的室外环境温度Tao和压缩机的频率f与室外风机的外机转速之间的对应关系：In still other alternative embodiments, the frequency of the compressor can also affect the heat release efficiency of the outdoor heat exchanger. Here, the higher the operating frequency of the compressor, the greater the amount of refrigerant discharged, and therefore the greater the amount of refrigerant flowing into the outdoor heat exchanger for heat exchange. Therefore, in this embodiment, the outdoor ambient temperature and the compressor frequency are used together to determine the temperature of the outdoor fan in the rapid cooling sterilization stage. Table 3 shows an optional outdoor ambient temperature Tao and the compressor Correspondence between frequency f and outdoor fan speed:

表3table 3

室外环境温度/频率Outdoor ambient temperature/frequency	F<51HzF<51Hz	51Hz≤f≤80Hz51Hz≤f≤80Hz	f>80Hzf>80Hz

22℃≤Tao≤29℃22℃≤Tao≤29℃	33	66	77
Tao>29℃Tao>29℃	77	77	77

在本实施例中，室外风机的转速档位设定与前文实施例中相同，在本实施例中，速冷灭菌阶段的室外风机的转速控制可以通过查找上表的方式确定。In this embodiment, the speed gear setting of the outdoor fan is the same as in the previous embodiment. In this embodiment, the speed control of the outdoor fan in the rapid cooling sterilization stage can be determined by looking up the above table.

在一些可选的实施例中，速冷灭菌阶段的关键之一是在短时间内将室内换热器降低并维持在第二灭菌温度以下；这里在速冷灭菌阶段，压缩机由于压缩机排出的高温冷媒是先流向室外换热器，则室外环境温度高低能够影响到冷媒在室外换热器与室外环境的散热效率，进而影响到流入室内换热器的冷媒温度，则本申请根据室外环境温度获取压缩机的频率，使得调整后的压缩机频率能够满足将室内换热器迅速降温至第二灭菌温度的要求。In some alternative embodiments, one of the keys to the rapid-cooling sterilization stage is to lower the indoor heat exchanger in a short time and maintain it below the second sterilization temperature; here, in the rapid-cooling sterilization stage, the compressor is The high-temperature refrigerant discharged from the compressor first flows to the outdoor heat exchanger, and the outdoor environment temperature can affect the heat dissipation efficiency of the refrigerant in the outdoor heat exchanger and the outdoor environment, and then affect the temperature of the refrigerant flowing into the indoor heat exchanger. The frequency of the compressor is obtained according to the outdoor ambient temperature, so that the adjusted compressor frequency can meet the requirement of rapidly cooling the indoor heat exchanger to the second sterilization temperature.

可选的，第三关联关系还包括室外环境温度与压缩机频率的一一对应关系,因此通过查找该关联关系就能够获取与当前的室外环境温度对应的压缩机频率。Optionally, the third association relationship further includes a one-to-one correspondence between the outdoor ambient temperature and the compressor frequency. Therefore, the compressor frequency corresponding to the current outdoor ambient temperature can be obtained by searching the association relationship.

例如，在室外环境温度大于第一外环温阈值时，控制压缩机以数值较大的第三频率运行，以增加排出的冷媒温度和冷媒量，提高冷媒在室外换热器与外界环境的热交换效率；而在室外环境温度小于第一外环温阈值时，此时冷媒与室外环境的换热效率较高,控制压缩机以数值小于第三频率的第四频率运行，可以有效减少压缩机在速冷灭菌阶段的功耗。For example, when the outdoor environment temperature is greater than the first outer ring temperature threshold, the compressor is controlled to run at a third frequency with a larger value to increase the discharged refrigerant temperature and refrigerant quantity, and increase the heat of the refrigerant in the outdoor heat exchanger and the external environment. Exchange efficiency; and when the outdoor environment temperature is less than the first outer ring temperature threshold, the heat exchange efficiency between the refrigerant and the outdoor environment is higher at this time, and the compressor is controlled to run at a fourth frequency that is less than the third frequency, which can effectively reduce the compressor Power consumption during the rapid cold sterilization phase.

在一些可选的实施例中，速冷灭菌阶段还包括根据室内环境温度获取的第二速冷灭菌参数,其中第二速冷灭菌参数包括节流装置的第二开度。在本实施例中，速冷灭菌阶段的室内风机是以中档转速运行，因此室内环境温度在一定程度上会影响到室内换热器的温度，因此为了能够保证速冷灭菌效果，本实施例中根据室内环境的不同温度状况，调节节流装置的开度，以改变流入室内换热器的低温冷媒的温度和压力，从而降低室内环境温度对速冷灭菌效果的不利影响。In some optional embodiments, the rapid cooling sterilization stage further includes a second rapid cooling sterilization parameter obtained according to the indoor ambient temperature, wherein the second rapid cooling sterilization parameter includes a second opening degree of the throttling device. In this embodiment, the indoor fan in the rapid-cooling sterilization stage runs at a mid-range speed. Therefore, the indoor ambient temperature will affect the temperature of the indoor heat exchanger to a certain extent. Therefore, in order to ensure the rapid-cooling sterilization effect, this implementation In the example, according to the different temperature conditions of the indoor environment, the opening degree of the throttling device is adjusted to change the temperature and pressure of the low-temperature refrigerant flowing into the indoor heat exchanger, thereby reducing the adverse effect of the indoor environment temperature on the rapid cooling sterilization effect.

可选的，空调器预设有一第四关联关系，预设的第四关联关系包括室内环境温度与开度的对应关系。表4示出的是一个可选的实施中室内环境温度Tp与节流装置的开度之间的对应关系。Optionally, the air conditioner presets a fourth association relationship, and the preset fourth association relationship includes the corresponding relationship between the indoor ambient temperature and the opening degree. Table 4 shows the correspondence between the indoor ambient temperature Tp and the opening of the throttle device in an optional implementation.

表4Table 4

室内环境温度Indoor ambient temperature	Tp≥22℃Tp≥22℃	Tp<22℃Tp<22℃
开度Opening	340340	350350

因此在本实施例中，速冷每件阶段的节流装置的开度控制可以通过查找上表的方式确定。Therefore, in this embodiment, the opening control of the throttling device for each stage of rapid cooling can be determined by looking up the above table.

在一些可选的实施例中，在执行步骤S101操作时，还可以控制启用电辅热装置进行辅助加热,以利用电辅热装置加快室内机内部的升温，缩短室内换热器达到第一灭菌温度所需的时长。In some optional embodiments, when the operation of step S101 is performed, the electric auxiliary heating device can also be controlled to perform auxiliary heating, so that the electric auxiliary heating device can be used to speed up the temperature rise of the indoor unit and shorten the indoor heat exchanger to reach the first temperature.
