背景技术Background technique
随着生活水平的提高和空调的普及，空调的生产数量和销售数量逐年增加。为了适应市场需求，空调需要批量生产，使得出厂后的空调大同小异，控制模式也较为单一，难以适配不同房间、不同时刻的热负荷变化。容易出现温度振荡、温度过冷或过热等现象，导致空调需要更多功耗将温度重新稳定到设定温度，使得空调节能效果较差。With the improvement of living standards and the popularization of air conditioners, the production and sales of air conditioners have increased year by year. In order to meet market demand, air conditioners need to be mass-produced, which makes the air conditioners after leaving the factory similar, and the control mode is also relatively simple, which makes it difficult to adapt to the changes in heat load in different rooms and at different times. Temperature oscillation, temperature overcooling or overheating are prone to occur, causing the air conditioner to consume more power to stabilize the temperature to the set temperature, resulting in poor energy-saving effect of the air conditioner.

由于在相关技术中，空调的控制模式也较为单一，难以适配不同房间、不同时刻的热负荷变化。容易出现温度振荡、温度过冷或过热等现象，需要额的功耗去调整浮动的温度，导致空调的节能效果较差。In the related technologies, the control mode of air conditioners is relatively simple, which makes it difficult to adapt to the changes in heat load in different rooms and at different times.

控制所述空调在所述当前时段内以所述目标运行频率运行。The air conditioner is controlled to operate at the target operating frequency during the current period.
这样空调在当前时段以目标运行功率运行，考虑到了室外温度对室内温度的影响，使得室内温度达到目标室内温度，平衡了房间的自然温度变化，刚好地将室内温度保持在目标室内温度，从而提高了空调的节能效果，也满足了用户需求。In this way, the air conditioner runs at the target operating power in the current period, taking into account the impact of outdoor temperature on indoor temperature, so that the indoor temperature reaches the target indoor temperature, balancing the natural temperature changes in the room, and just keeping the indoor temperature at the target indoor temperature, thereby improving the energy-saving effect of the air conditioner and meeting user needs.

以下，通过具体示例性方案对本申请权利要求要求保护的内容，进行解释说明，以便本领域技术人员更好地理解本申请权利要求的保护范围。可以理解的是，以下示例性方案不对本申请的保护范围进行限定，仅用于解释本申请。The following is an explanation of the content claimed in the claims of this application through specific exemplary schemes, so that those skilled in the art can better understand the scope of protection of the claims of this application. It is understood that the following exemplary schemes do not limit the scope of protection of this application, but are only used to explain this application.
示例性地，参照图2，在本申请空调的控制方法的一实施例中，所述空调的控制方法包括以下步骤：Exemplarily, referring to FIG. 2 , in one embodiment of the air conditioner control method of the present application, the air conditioner control method includes the following steps:
步骤S10、确定当前时段内空调待机状态下，所在房间的热负荷功率；Step S10, determining the heat load power of the room when the air conditioner is in standby mode during the current period;
在一实施例中，空调预先设置了多个时段，当前时段是指从当前时刻到这个预设时刻的结束时间。在一实施例中，当空调运行至预设时段时，执行步骤S10，当前时刻即为空调运行值预设时段时，可以理解的是，此时的当前时段包括整个预设时段，或者当空调启动时，执行步骤S10，也即空调开始调温时，当前时刻即为空调的启动时刻，确定启动的当前时刻是否在预设时段内，若在预设时段内，则当前时段是从当前启动的时刻到预设时段的结束时刻，可以理解的是，此时的当前时段大多是包括部分预设时段。In one embodiment, the air conditioner is pre-set with multiple time periods, and the current time period refers to the time from the current moment to the end of this preset moment. In one embodiment, when the air conditioner runs to the preset time period, step S10 is executed, and the current moment is the preset time period of the air conditioner operation. It can be understood that the current time period at this time includes the entire preset time period, or when the air conditioner is started, step S10 is executed, that is, when the air conditioner starts to adjust the temperature, the current moment is the start-up time of the air conditioner, and it is determined whether the current time of startup is within the preset time period. If it is within the preset time period, the current time period is from the current startup moment to the end of the preset time period. It can be understood that the current time period at this time mostly includes part of the preset time period.
确定当前时段内，若空调处于待机状态下，空调所在房间的热负荷功率。空调在待机状态下，不对室内温度进行调节，也即不会对室内温度产生影响。但是室内温度会随着室外温度的影响而发生自然的变化，确定当前时段内室内外自然发生的热负荷交换的功率，即热负荷功率。Determine the heat load power of the room where the air conditioner is located if the air conditioner is in standby mode during the current period. When the air conditioner is in standby mode, it does not adjust the indoor temperature, which means it will not affect the indoor temperature. However, the indoor temperature will change naturally with the influence of the outdoor temperature. Determine the power of the heat load exchange that occurs naturally between the indoor and outdoor during the current period, that is, the heat load power.
热负荷功率主要与时间、室内外温度有关，室外温度会随着季度、月份、时段等的变化而发生变化，因此其对室内温度的影响也会随着时间的不同发生变化。例如在夏天，室外环境较热，这样室内温度也会受外界影响，对应升高，在冬天，室外环境较冷，室内温度也会受外界影响，对应降低。室外温度造成室内温度发生温度的变化原因是发生了热负荷的交换，热负荷功率则可以表示室外温度和室外温度热负荷的交换情况。由于室内外热负荷可以相互交换，则热负荷功率值存在正负，热负荷功率绝对值的大小可以表示单位时间内热负荷转移的数量，室内外温差越大，热负荷功率绝对值越大，反之越小。The heat load power is mainly related to time and indoor and outdoor temperatures. The outdoor temperature will change with the season, month, time period, etc., so its impact on the indoor temperature will also change with time. For example, in summer, the outdoor environment is hotter, so the indoor temperature will also be affected by the outside world and will rise accordingly. In winter, the outdoor environment is colder, and the indoor temperature will also be affected by the outside world and will decrease accordingly. The reason why the outdoor temperature causes the indoor temperature to change is the exchange of heat load. The heat load power can indicate the exchange of outdoor temperature and outdoor temperature heat load. Since the indoor and outdoor heat loads can be exchanged with each other, the heat load power value can be positive or negative. The absolute value of the heat load power can indicate the amount of heat load transfer per unit time. The greater the indoor and outdoor temperature difference, the greater the absolute value of the heat load power, and vice versa.
房间的热负荷功率可以通过以下公式计算得到：The heat load power of the room can be calculated by the following formula:
夏季： summer:
冬季： winter:
其中，P_e表示热负荷功率，C为空气比热容，p为空气密度，V为房间体积，T1表示空调待机状态下的起始温度，T2表示空调待机状态下的截止温度，T表示从T1变化至T2的总时长。Among them, P_e represents the heat load power, C is the specific heat capacity of air, p is the air density, V is the room volume, T1 represents the starting temperature of the air conditioner in the standby state, T2 represents the end temperature of the air conditioner in the standby state, and T represents the total time from T1 to T2.
需要说明的是，在确定热负荷功率前，需要确定T1和T2的所在季节，根据季节情况 确定计算公式。由于室内外热负荷可以相互交互，则热负荷功率值存在正负。例如在夏季的正午，室外温度一般会高于室内温度，会造成室内温度升高，P_e＞0，在夏季的凌晨，室外温度一般会低于室内温度，会造成室内温度降低，P_e＜0。It should be noted that before determining the heat load power, it is necessary to determine the seasons of T1 and T2. Determine the calculation formula. Since the indoor and outdoor heat loads can interact with each other, the heat load power value can be positive or negative. For example, at noon in summer, the outdoor temperature is generally higher than the indoor temperature, which will cause the indoor temperature to rise, P_e>0. In the early morning of summer, the outdoor temperature is generally lower than the indoor temperature, which will cause the indoor temperature to drop, P_e<0.
根据上述公式可以得知，计算空调的热负荷功率需要一个时间段，使得温度发生改变，从而检测空调待机状态下房间内的温度变化及其变化所需时间，才能计算出这个时间段的热负荷功率。According to the above formula, it can be known that calculating the heat load power of the air conditioner requires a period of time for the temperature to change, so as to detect the temperature change in the room when the air conditioner is in standby state and the time required for the change, so as to calculate the heat load power of this period of time.
在一实施例中，获取时段信息与热负荷功率的关联关系，并根据时段信息与热负荷功率的关联关系，确定当前时段对应的所述热负荷功率。In one embodiment, the correlation between the time period information and the heat load power is obtained, and the heat load power corresponding to the current time period is determined according to the correlation between the time period information and the heat load power.
空调所在房间的热负荷功率在当前时段内任意时刻的热负荷功率是相同的。时段信息可以是在当前时段之前的任意时间段，因此可以在当前时段前获取在时段信息对应的历史数据，并根据历史数据得到时段信息与热负荷功率的关联关系，然后确定在时段信息中与当前时段匹配的时段，并根据时段信息与热负荷功率的关联关系确定这个时段的热负荷功率，作为当前时段的热负荷功率。The heat load power of the room where the air conditioner is located is the same at any time in the current period. The period information can be any time period before the current period, so the historical data corresponding to the period information can be obtained before the current period, and the correlation between the period information and the heat load power can be obtained based on the historical data, and then the period matching the current period in the period information is determined, and the heat load power of this period is determined based on the correlation between the period information and the heat load power as the heat load power of the current period.
进一步地，空调待机状态下，记录空调所在房间的室内温度的变化以及对应的时间信息；根据所记录的信息，计算获得各个时段对应的热负荷功率；生成时段信息和热负荷功率的关联关系。Furthermore, when the air conditioner is in standby mode, the change in indoor temperature of the room where the air conditioner is located and the corresponding time information are recorded; based on the recorded information, the heat load power corresponding to each time period is calculated; and the correlation between the time period information and the heat load power is generated.
在一实施例中，由于天气的季节性变化，同一季度或同一月份下的同一时区内的热负荷功率是相同的，因此空调可以记录每一季度下或每一月份下的某一天内的不同时段内，室内的温度变化及对应的变化时间信息，根据室内的温度变化及对应的变化时间信息，通过上述公式可以确定在这个变化时间内的热负荷功率，确定变化时间所在的时段，变化时间内对应的热负荷功率即可以与所在时段进行关联，从而确定不同时段关联的热负荷功率，从而生成时段信息和热负荷功率的关联关系。In one embodiment, due to seasonal changes in the weather, the heat load power in the same time zone in the same quarter or the same month is the same. Therefore, the air conditioner can record the indoor temperature changes and the corresponding change time information in different time periods of a certain day in each quarter or each month. According to the indoor temperature changes and the corresponding change time information, the heat load power within this change time can be determined by the above formula, and the time period in which the change time is located can be determined. The corresponding heat load power within the change time can be associated with the time period, thereby determining the heat load power associated with different time periods, thereby generating a correlation between the time period information and the heat load power.
与当前时段匹配的时段可以是相同季度、相同月份或相同日期下的相同时区对应的时段。例如，当前时段可以是2022年8月5日的下午2:35-3:00，那么与当前时段匹配的时段信息可以是2022年8月5日的下午2:00-3:00，也可以是2021年夏季的下午2:00-3:00，也可以是2021年8月的下午2:00-3:00，也可以是2021年8月5日的下午2:00-3:00。The time period that matches the current time period can be the time period corresponding to the same time zone in the same quarter, the same month, or the same date. For example, the current time period can be 2:35-3:00 p.m. on August 5, 2022, then the time period information that matches the current time period can be 2:00-3:00 p.m. on August 5, 2022, or 2:00-3:00 p.m. in the summer of 2021, or 2:00-3:00 p.m. in August 2021, or 2:00-3:00 p.m. on August 5, 2021.
在一实施例中，参照图5，获取月份、时区、热负荷功率的通用映射表，根据所述通用预设表确定需要记录所在房间的室内温度的变化以及对应的时间信息的时段，在进入这个时段时，若空调在空调待机状态下，开始记录，然后在结束这个时段后，根据记录的这个时段内室内温度的变化以及对应的时间信息确定这个时段的热负荷功率，然后更新通用 映射表，通过通用映射表，可以确定时段信息和热负荷功率的关联关系。In one embodiment, referring to FIG. 5, a general mapping table of month, time zone, and heat load power is obtained, and a time period in which the change of indoor temperature in the room and the corresponding time information need to be recorded is determined according to the general preset table. When entering this time period, if the air conditioner is in the air conditioner standby state, recording starts, and then after the end of this time period, the heat load power of this time period is determined according to the change of indoor temperature in this time period and the corresponding time information, and then the general preset table is updated. Mapping table: Through the general mapping table, the correlation between time period information and heat load power can be determined.
在一实施例中，相邻时间内的热负荷率也是相同的，时段是预先设置的，因此可以确定每个时段对应的起始时刻，在到达每个时段对应的起始时刻时，记录在起始时刻的室内温度。这样在空调启动时，执行步骤S10时，可以确定当前时刻所在的当前时段以及当前室内温度，获取当前时段的起始时刻以及起始时刻时的室内温度、当前时刻和当前温度，记录到从起始时刻到当前时刻的温度变化，以及发生温度变化的时间信息为起始时刻至当前时刻。根据起始时刻以及起始时刻时的室内温度、当前时刻和当前温度和上述公式即可以确定当前时段内的热负荷功率。In one embodiment, the heat load rate in adjacent time periods is also the same, and the time periods are pre-set, so the starting time corresponding to each time period can be determined, and when the starting time corresponding to each time period is reached, the indoor temperature at the starting time is recorded. In this way, when the air conditioner is started, when executing step S10, the current time period and the current indoor temperature of the current time period can be determined, the starting time of the current time period and the indoor temperature at the starting time, the current time and the current temperature are obtained, and the temperature change from the starting time to the current time is recorded, and the time information of the temperature change is from the starting time to the current time. According to the starting time and the indoor temperature at the starting time, the current time and the current temperature and the above formula, the heat load power in the current time period can be determined.
进一步地，若时段信息与热负荷功率的关联关系中，不存在与当前时段匹配的时段信息，则采用预设的热负荷功率。Furthermore, if there is no time period information matching the current time period in the association relationship between the time period information and the heat load power, the preset heat load power is used.
若时段信息与热负荷功率的关联关系中，不存在与当前时段匹配的时段，则采用预设的热负荷功率。时段信息和热负荷功率的关联关系可以是针对个别空调确定在其所在房间的关联关系。空调安装在房间内后，才能确定其所在房间在过去时段的待机状态下的热负荷功率，才能建立时段信息与热负荷功率的关联关系。但是在许多情况下，例如在空调才安装到房间后，与当前时段匹配的过去时段内，空调还未安装，则可空调无法确定在匹配的过去时段内中房间的热负荷功率，则空调可以获取在出厂前预存的时段信息与热负荷功率的通用关联关系，根据这个通用关系，确定与当前时段匹配的预存时段对应的预存热负荷功率，作为当前时段内房间的热负荷功率。If there is no time period matching the current time period in the association relationship between time period information and heat load power, the preset heat load power is used. The association relationship between time period information and heat load power can be an association relationship determined for an individual air conditioner in the room where it is located. Only after the air conditioner is installed in the room can the heat load power of the room in the standby state in the past time period be determined, and the association relationship between time period information and heat load power can be established. However, in many cases, for example, after the air conditioner is installed in the room, the air conditioner has not been installed in the past time period matching the current time period, so the air conditioner cannot determine the heat load power of the room in the matching past time period. In this case, the air conditioner can obtain the general association relationship between time period information and heat load power pre-stored before leaving the factory, and determine the pre-stored heat load power corresponding to the pre-stored time period matching the current time period according to this general relationship as the heat load power of the room in the current time period.
步骤S20、确定所述当前时段内，所述空调理想运行状态下使室内温度达到目标室内温度所需要的需求功率；Step S20, determining the required power required to make the indoor temperature reach the target indoor temperature under the ideal operating state of the air conditioner during the current period;
在一实施例中，理想运行状态是指在空调运行过程时室内外温度不发生热负荷传递的理论状态。在理想运行状态下，对室内温度产生影响的热量源只有空调。使当前室内温度达到目标室内温度所需要的热负荷功率即为需求功率。In one embodiment, the ideal operating state refers to a theoretical state in which no heat load transfer occurs between the indoor and outdoor temperatures during the operation of the air conditioner. In the ideal operating state, the only heat source that affects the indoor temperature is the air conditioner. The heat load power required to make the current indoor temperature reach the target indoor temperature is the required power.
在一实施例中，获取所述房间的体积及房间内的当前室内温度；根据所述体积、当前室内温度和目标室内温度的温差、所述当前时段的时长确定所述需求功率。In one embodiment, the volume of the room and the current indoor temperature of the room are obtained; and the required power is determined according to the volume, the temperature difference between the current indoor temperature and the target indoor temperature, and the duration of the current time period.
目标室内温度是经过空调调温后，室内需要达到的温度。目标室内温度可以是用户设定的温度。获取空调所在房间的体积，以及房间的当前室内温度，确定房间的目标室内温度，以及当前时段的时长，空调需要空调使当前室内温度达到目标室内温度所需要的时长一般等于或小于当前时段的时长，但是在理想状态下，室内达到目标室内温度后，空调就不需要对房间进行调温。但是实际运行过程中，室外温度是时刻影响室内的，因此需要将 当前室内温度达到目标室内温度所需要的时长设定为当前时段的总时长，这样计算出的需求功率在当前时段的运行过程中，才具有参考性。温度一般可以达到目标室内温度。然后根据以下公式计算出需求功率：
The target indoor temperature is the temperature that the room needs to reach after the air conditioner is used to adjust the temperature. The target indoor temperature can be the temperature set by the user. Get the volume of the room where the air conditioner is located, as well as the current indoor temperature of the room, determine the target indoor temperature of the room, and the duration of the current period. The time required for the air conditioner to make the current indoor temperature reach the target indoor temperature is generally equal to or less than the duration of the current period. However, in an ideal state, after the room reaches the target indoor temperature, the air conditioner does not need to adjust the room temperature. However, in actual operation, the outdoor temperature always affects the indoor temperature, so it is necessary to The time required for the current indoor temperature to reach the target indoor temperature is set as the total time of the current period, so that the calculated required power is only referenced during the operation of the current period. The temperature can generally reach the target indoor temperature. Then calculate the required power according to the following formula:
其中，P_u表示需求功率，C为空气比热容，p为空气密度，V为房间体积，Tin表示当前室内温度，Ts表示目标室内温度，T表示当前时段的时长，需要注意的是，需求功率的值为正值。Among them, Pu represents the required power, C is the specific heat capacity of air, p is the air density, V is the room volume, Tin represents the current indoor temperature, Ts represents the target indoor temperature, and T represents the duration of the current period. It should be noted that the value of the required power is a positive value.
步骤S30、根据所述热负荷功率和所述需求功率，确定所述空调在所述当前时段内的目标运行频率；Step S30, determining a target operating frequency of the air conditioner in the current period according to the heat load power and the required power;
在一实施例中，需求功率是空调在理想运行状态下将当前温度调整至室内目标温度所需的功率，但实际运行过程中，室外环境温度是会对室内温度发生影响，因此针对空调所在房间的当前时段热负荷功率，可以计算出空调将在这个时段内运行时实际的目标运行功率。计算公式如下：
P_r＝P_u+P_eIn one embodiment, the required power is the power required for the air conditioner to adjust the current temperature to the indoor target temperature under ideal operating conditions. However, in actual operation, the outdoor ambient temperature will affect the indoor temperature. Therefore, based on the heat load power of the room where the air conditioner is located during the current period, the actual target operating power of the air conditioner when it is running during this period can be calculated. The calculation formula is as follows:
P_r＝P_u+P_e
步骤S40、控制所述空调在所述当前时段内以所述目标运行频率运行。Step S40: Control the air conditioner to operate at the target operating frequency during the current period.
在一实施例中，在当前时段内，需求功率可以确定空调理想运行状态下对房间产生的热负荷交换，根据热负荷功率可以确定室外环境与室内的热负荷交换，这样可以确定出在这个当前时段内，空调实际上需要对室内产生的热负荷交换，然后根据当前时段的运行时长可以确定这个室内空调的运行功率。因此，根据需求功率与热负荷功率计算得到目标运行功率，实际上是要计算在当前时段内，除了空调提供给房间内的热负荷外，还包括室外对房间内热负荷的影响。在当前时段内，以目标运行功率运行，空调在当前时段产生的热负荷，在考虑到室外环境影响后，可以刚好满足从当前室内温度运行到目标运行温度的需求，使得很好的平衡了节能需求和调温需求。In one embodiment, during the current period, the required power can determine the heat load exchange generated by the air conditioner in the ideal operating state of the room, and the heat load exchange between the outdoor environment and the indoor environment can be determined based on the heat load power. In this way, it can be determined that during the current period, the air conditioner actually needs to exchange the heat load generated indoors, and then the operating power of the indoor air conditioner can be determined based on the operating time of the current period. Therefore, the target operating power is calculated based on the required power and the heat load power. In fact, it is necessary to calculate the influence of the outdoor on the heat load in the room in addition to the heat load provided by the air conditioner in the room during the current period. During the current period, the heat load generated by the air conditioner during the current period can just meet the demand of running from the current indoor temperature to the target operating temperature after taking into account the influence of the outdoor environment, so that the energy saving demand and the temperature control demand are well balanced.
在本实施例公开的技术方案中，先确定当前时段内空调待机状态下，所在房间的热负荷功率；确定所述当前时段内，所述空调理想运行状态下使室内温度达到目标室内温度所需要的需求功率；根据所述热负荷功率和所述需求功率，确定所述空调在所述当前时段内的目标运行频率；控制所述空调在所述当前时段内以所述目标运行频率运行。这样通过在当前时段内空调所在房间热负荷功率和空调需求功率，综合确定出空调在这个时段内实际需要运行的目标运行功率，在考虑到了室外对室内的影响，平衡了空调造成的温度变化和房间的自然温度变化，满足用户需求及房间热负荷变化，舒适性更高，针对房间的热负荷 确定的运行频率，可以有效避免能源的浪费，提高空调的节能效果。并且可以将当前室内温度快速又节能地提升到目标室内温度，并且在达到目标室内温度后，以目标运行功率运行，恰好地将室内温度在目标室内温度，从而提高了空调的控温性能。In the technical solution disclosed in this embodiment, the heat load power of the room where the air conditioner is located in the standby state during the current time period is first determined; the required power required for the air conditioner to reach the target indoor temperature under the ideal operating state during the current time period is determined; the target operating frequency of the air conditioner during the current time period is determined based on the heat load power and the required power; and the air conditioner is controlled to operate at the target operating frequency during the current time period. In this way, the target operating power that the air conditioner actually needs to operate during this time period is comprehensively determined by measuring the heat load power of the room where the air conditioner is located during the current time period and the required power of the air conditioner. This balances the temperature changes caused by the air conditioner and the natural temperature changes of the room while taking into account the impact of the outdoor on the indoor environment, thereby meeting user needs and room heat load changes, providing higher comfort, and targeting the heat load of the room. The determined operating frequency can effectively avoid energy waste and improve the energy-saving effect of the air conditioner. It can also quickly and energy-efficiently raise the current indoor temperature to the target indoor temperature, and after reaching the target indoor temperature, it will operate at the target operating power to keep the indoor temperature exactly at the target indoor temperature, thereby improving the temperature control performance of the air conditioner.
在一实施例中，参照图3，基于上述任一实施例，在本申请空调的控制方法的另一实施例中，所述空调的控制方法还包括：In one embodiment, referring to FIG. 3 , based on any of the above embodiments, in another embodiment of the air conditioner control method of the present application, the air conditioner control method further includes:
步骤S201、将所述房间划分为多个子区域，确定各子区域对应的需求功率；Step S201: Divide the room into multiple sub-areas, and determine the required power corresponding to each sub-area;
步骤S202、根据所述各子区域的热负荷功率和需求功率，确定所述目标运行功率。Step S202: Determine the target operating power according to the heat load power and required power of each sub-area.
在一实施例中，房间内不同区域会存在不同的当前温度，例如，在靠窗处，由于通风原因，温度一般会比内部低，而在房间内部，温度一般会比通风出温度高。因此，不同区域对应的当前温度调整到目标设定温度所需要的热负荷交换不同，对应的需求功率也会不同。对应地，将房间划分为多个子区域，确定各子区域对应的当前温度，根据各子区域和各子区域的目标温度的温差，确定各子区域对应的需求功率。In one embodiment, different areas in the room may have different current temperatures. For example, near the window, due to ventilation, the temperature is generally lower than the inside, while inside the room, the temperature is generally higher than the ventilated outlet temperature. Therefore, the heat load exchange required to adjust the current temperature corresponding to different areas to the target set temperature is different, and the corresponding power requirements are also different. Correspondingly, the room is divided into multiple sub-areas, the current temperature corresponding to each sub-area is determined, and the power requirements corresponding to each sub-area are determined according to the temperature difference between each sub-area and the target temperature of each sub-area.
各子区域的目标温度可以均为目标室内温度，也可以是不同的，例如房间内针对人体活动的区域，如床，这个区域的目标温度要达到目标温度或者略低于目标室内温度；而在其他区域的目标温度可以高于目标室内温度，这样增加了用户使用感，提高了空调的自定义性。The target temperature of each sub-area can be the target indoor temperature or different. For example, in the area of the room for human activities, such as the bed, the target temperature of this area should reach the target temperature or be slightly lower than the target indoor temperature; while the target temperature in other areas can be higher than the target indoor temperature. This increases the user experience and improves the customization of the air conditioner.
根据各子区域的热负荷功率和需求功率，各子区域的热负荷功率可以根据各子区域对应的时段信息和热负荷功率的关联关系确定，因此各子区域的热负荷功率可以是不相同的。确定各子区域对应的目标运行功率，将各子区域的和值，作为在所述当前时段内从室内温度达到目标室内温度时所需要的目标运行功率。According to the heat load power and required power of each sub-area, the heat load power of each sub-area can be determined according to the correlation between the time period information corresponding to each sub-area and the heat load power, so the heat load power of each sub-area can be different. The target operating power corresponding to each sub-area is determined, and the sum of the values of each sub-area is used as the target operating power required when the indoor temperature reaches the target indoor temperature in the current time period.
在一实施例中，获取各子区域对应的目标温度、当前温度和体积；根据各子区域的体积、当前温度、目标温度、所述当前时段的时长，确定各子区域对应的需求功率。具体公式如下：
In one embodiment, the target temperature, current temperature and volume corresponding to each sub-area are obtained; and the required power corresponding to each sub-area is determined according to the volume, current temperature, target temperature and duration of the current period of each sub-area. The specific formula is as follows:
其中，P_ui表示子区域的需求功率，C为空气比热容，p为空气密度，Vi为子区域的体积，Tini表示子区域的当前温度，Ts表示子区域的目标温度，T表示当前时段的时长，需要注意的是，需求功率的值为正值。Among them, P_u i represents the required power of the sub-area, C is the specific heat capacity of air, p is the air density, Vi is the volume of the sub-area, Tin i represents the current temperature of the sub-area, Ts represents the target temperature of the sub-area, and T represents the duration of the current period. It should be noted that the value of the required power is a positive value.
在本实施例公开的技术方案中，获取所述房间的体积及房间内的当前温度；根据所述体积、当前温度和目标室内温度的温差、所述当前时段的时长确定所述需求功率。因为房 间不同区域的当前温度存在差异，分区域确定需求功率，可以准确获得所在房间的需求功率，进一步提高空调控温性能和节能效果。In the technical solution disclosed in this embodiment, the volume of the room and the current temperature in the room are obtained; the required power is determined according to the volume, the temperature difference between the current temperature and the target indoor temperature, and the duration of the current period. The current temperature in different areas of the room is different. By determining the required power by area, the required power of the room can be accurately obtained, further improving the temperature control performance and energy-saving effect of the air conditioner.
在一实施例中，参照图4，基于上述任一实施例，在本申请空调的控制方法的又一实施例中，所述空调的控制方法还包括：In one embodiment, referring to FIG. 4 , based on any of the above embodiments, in another embodiment of the air conditioner control method of the present application, the air conditioner control method further includes:
步骤S101、将所述房间划分为若干子区域，并记录空调待机状态下，空调所在房间的各子区域的室内温度的变化及对应的时间信息；Step S101, dividing the room into several sub-areas, and recording the indoor temperature changes and corresponding time information of each sub-area of the room where the air conditioner is located when the air conditioner is in standby state;
步骤S102、根据所记录的信息，计算获得各个时段各子区域对应的热负荷功率；Step S102: Calculate and obtain the heat load power corresponding to each sub-area in each time period according to the recorded information;
步骤S103、生成时段信息、子区域和热负荷功率的关联关系，以供确定当前时段所述房间的热负荷功率。Step S103: Generate an association relationship between time period information, sub-areas and heat load power to determine the heat load power of the room in the current time period.
在一实施例中，房间内不同区域不仅会存在不同的当前温度，由于其在房间内位置的不同，室外温度对室内温度的热负荷交换也不同，例如在房间四周，由于室外的距离更近，温度受室外影响越大，热负荷功率越大，而在房间内部，由于室外的距离更近，温度受室外影响越小，热负荷功率越小。因此，不同区域对应的热负荷功率不同，需要根据不同区域确定其对应的热负荷功率。对应的，将房间划分为多个子区域，确定各子区域在当前时段内的热负荷功率。In one embodiment, different areas in a room not only have different current temperatures, but also have different heat load exchanges between outdoor temperature and indoor temperature due to their different positions in the room. For example, around the room, since the distance to the outdoors is closer, the temperature is more affected by the outdoors, and the heat load power is greater. However, inside the room, since the distance to the outdoors is closer, the temperature is less affected by the outdoors, and the heat load power is smaller. Therefore, the heat load power corresponding to different areas is different, and the heat load power corresponding to different areas needs to be determined. Correspondingly, the room is divided into multiple sub-areas, and the heat load power of each sub-area in the current time period is determined.
在确定各子区域在当前时段内的热负荷功率之前，需要将房间划分为上述各子区域，空调需要在待机状态下，可以通过红外探测仪记录空调所在房间内的各子区域的室内温度的变化以及对应的时间信息，即温度在一个过去时段内，各子区域的温度从起始温度变化到截止温度，以及对应的变化时间。并将其进行保存。并根据起始温度变化到截止温度，以及对应的变化时间计算各子区域在这个过去时段内对应的热负荷功率。Before determining the heat load power of each sub-area in the current period, the room needs to be divided into the above sub-areas. The air conditioner needs to be in standby mode. The infrared detector can record the indoor temperature changes of each sub-area in the room where the air conditioner is located and the corresponding time information, that is, the temperature changes from the starting temperature to the end temperature of each sub-area in a past period, and the corresponding change time. And save it. And calculate the corresponding heat load power of each sub-area in this past period according to the change from the starting temperature to the end temperature and the corresponding change time.
具体地，获取过去时段内起始温度变化到截止温度，以及对应的变化时间；根据各子区域的体积、起始温度变化到截止温度，以及对应的变化时间，确定在这个过去时段内，各子区域对应的热负荷功率。具体公式如下：Specifically, obtain the change from the starting temperature to the end temperature and the corresponding change time in the past period; determine the heat load power corresponding to each sub-area in this past period according to the volume of each sub-area, the change from the starting temperature to the end temperature, and the corresponding change time. The specific formula is as follows:
夏季： summer:
冬季： winter:
其中，P_ei表示子区域的热负荷功率，C为空气比热容，p为空气密度，Vi为子区域的体积，T1i表示子区域的起始温度，T2i表示子区域的截止温度，T表示变化时间，需要注意的是，热负荷功率因为季节的不同，计算公式不同。Among them, P_e i represents the heat load power of the sub-area, C is the specific heat capacity of air, p is the air density, Vi is the volume of the sub-area, T1 i represents the starting temperature of the sub-area, T2 i represents the cut-off temperature of the sub-area, and T represents the change time. It should be noted that the calculation formula of the heat load power is different due to different seasons.
根据若个过去时段及其时段内的热负荷功率生成各子区域对应的时段信息和热负荷功率的关联关系。根据将当前时段与各子区域对应的时段信息进行匹配，如匹配到过去时 段，则根据过去时段关联热负荷功率作为该子区域当前时段的热负荷功率，若未匹配到过去时段，则将相邻的子区域在当前时段内的热负荷功率作为这个未匹配到过去时段的子区域在当前时段内的热负荷功率。The relationship between the time period information and the heat load power of each sub-area is generated based on several past time periods and the heat load power within the time period. If a past period is matched, the heat load power associated with the past period is used as the heat load power of the sub-area in the current period. If the past period is not matched, the heat load power of the adjacent sub-area in the current period is used as the heat load power of the sub-area that is not matched with the past period in the current period.
进一步地，计算到各子区域的热负荷功率后，可以根据各子区域的需求功率，对应计算出在实际运行过程中，各个子区域从当前温度至目标温度需要空调提供的目标功率，再各区域的目标功率的总和确定空调在当前时段内的目标运行功率。也可以先根据各子区域的热负荷功率的总和计算整个房间的热负荷功率，计算公式如下：
Furthermore, after calculating the heat load power of each sub-area, the target power required by the air conditioner from the current temperature to the target temperature in each sub-area can be calculated according to the required power of each sub-area during the actual operation, and then the target operating power of the air conditioner in the current period can be determined by the sum of the target powers of each area. The heat load power of the entire room can also be calculated based on the sum of the heat load power of each sub-area. The calculation formula is as follows:
其中，P_e(i)是指整个房间的总热负荷功率，p_ei是指各子区域的热负荷功率，根据房间的总热负荷功率和需求功率确定空调在当前时段的总运行功率。Among them, P_e(i) refers to the total heat load power of the entire room, p_ei refers to the heat load power of each sub-area, and the total operating power of the air conditioner in the current period is determined based on the total heat load power and demand power of the room.
在本实施例公开的技术方案中，空调待机状态下，记录空调所在房间的室内温度的变化以及对应的时间信息；根据所记录的信息，计算获得各个时段对应的热负荷功率；生成时段信息和热负荷功率的关联关系。因为房间不同区域受室外环境的影响不同，对应热负荷功率也不相同，因此分区域计算热负荷功率，可以准确得到所在房间的热负荷功率，进一步提高空调控温性能和节能效果。In the technical solution disclosed in this embodiment, when the air conditioner is in standby mode, the indoor temperature change of the room where the air conditioner is located and the corresponding time information are recorded; based on the recorded information, the heat load power corresponding to each time period is calculated; and the correlation between the time period information and the heat load power is generated. Because different areas of the room are affected differently by the outdoor environment, the corresponding heat load power is also different. Therefore, by calculating the heat load power by area, the heat load power of the room can be accurately obtained, further improving the temperature control performance and energy saving effect of the air conditioner.
