In the embodiment of the present invention, the water supply temperature of the water path system 3 may be understood as the water outlet temperature of the heat pump system 2.
In the present embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may be a water source heat pump system, a ground source heat pump system, a dual source heat pump system, or the like.

In the apparatus shown in fig. 2, a processor 1001 may be used to call a control program of an environment conditioning device stored in a memory 1002 and perform the relevant step operations of a control method of the environment conditioning device in the following embodiments.
The embodiment of the invention also provides a control method of the environment adjusting device, which is applied to the environment adjusting device.
Referring to fig. 3, an embodiment of a control method of the environment conditioning apparatus of the present application is presented. In this embodiment, the control method of the environment adjustment device includes:
step S10, acquiring a first environment temperature of an indoor space regulated by the waterway system;
the first ambient temperature may be obtained by acquiring data detected by an ambient parameter module provided in the indoor space.
The number of first ambient temperatures here may be one or more than one. When there is more than one first ambient temperature, the more than one ambient temperatures are detected at different times, respectively.
Specifically, an initial temperature of a target water supply temperature of the waterway system is obtained, a cooling operation or a heating operation of the heat pump system is controlled according to the initial temperature, and step S10 is performed.
And step S20, when the first ambient temperature reaches a preset condition, adjusting the current target water supply temperature of the waterway system, and controlling the heat pump system to operate according to the adjusted target water supply temperature so as to improve the heat exchange quantity carried by water supply of the waterway system.
The preset condition is specifically a condition which needs to be reached by the first ambient temperature when the load of the indoor space is excessive. The preset condition includes a target temperature range to be reached by the first ambient temperature, and may also include a target number relationship or a target size relationship between the first ambient temperature and a preset temperature threshold.
When the first ambient temperature reaches a preset condition, the current load of the indoor space is indicated to be overlarge, and the requirement of further improving the temperature regulation speed of the indoor space is met.
The adjustment direction of the target water supply temperature of the waterway system can be determined according to the current operation mode of the heat pump system, and different operation modes correspond to different adjustment directions of the target water supply temperature. In this embodiment, when the heat pump system is in a cooling operation, the current target water supply temperature of the water path system is reduced; and when the heat pump system is in heating operation, increasing the current target water supply temperature of the waterway system. In other embodiments, when the heat pump system is a single-cooled system, the step of adjusting the current target water supply temperature of the water path system may be set to reduce the current target water supply temperature of the water path system by default; when the heat pump system is a mono-thermal system, the step of adjusting the current target water supply temperature of the water path system may be set to increase the current target water supply temperature of the water path system by default.
The manner of adjusting the target water supply temperature may include: the current target water supply temperature of the waterway system is adjusted to a preset target value, wherein the target value is the adjusted target water supply temperature, and different operation modes correspond to different target values; adjusting the current target water supply temperature of the waterway system according to a preset temperature adjustment value (such as a temperature adjustment proportion or a temperature adjustment amplitude) or a temperature adjustment value (such as a temperature adjustment proportion or a temperature adjustment amplitude) determined according to the actual operation condition of the environment adjusting equipment, and taking the obtained target value as the adjusted target water supply temperature; the target water supply temperature of the waterway system can be adjusted according to the preset temperature adjustment rate, and the heat pump system is controlled to operate according to the adjusted target water supply temperature in the adjustment process.
After the adjusted target water supply temperature is obtained, the data detected by the temperature sensor can be read to obtain the current water supply temperature of the waterway system, and the current water supply temperature of the waterway system and the adjusted target water supply temperature are determined to control the operation of the heat pump system. Specifically, when the current water supply temperature of the water path system is greater than the adjusted target water supply temperature during refrigeration operation of the heat pump system, the heat pump system is controlled to operate so as to reduce the actual water supply temperature of the water path system (such as increasing the operation frequency of a compressor, etc.); when the current water supply temperature of the water path system is smaller than the adjusted target water supply temperature, the heat pump system is controlled to operate so as to improve the actual water supply temperature of the water path system (such as reducing the operation frequency of a compressor). When the water path system is in heating operation and the current water supply temperature of the heat pump system is higher than the adjusted target water supply temperature, the heat pump system is controlled to operate so as to reduce the actual water supply temperature of the water path system (such as reducing the operation frequency of a compressor and the like); when the current water supply temperature is smaller than the adjusted target water supply temperature, the heat pump system is controlled to operate so as to improve the actual water supply temperature of the waterway system (such as improving the operation frequency of the compressor). Based on this, can guarantee that waterway system's water supply temperature can accurately reach the target water supply temperature after the adjustment, make waterway system provide indoor space's heat exchange volume can accurately satisfy indoor space's actual load demand.
According to the control method of the environment adjusting device, when the first environment temperature of the indoor space adjusted by the water channel system reaches a preset condition, the difference (difference value) between the environment temperature of the indoor space and the set temperature is considered to be large, the current target water supply temperature of the water channel system is adjusted at the moment, the heat pump system is controlled to operate according to the adjusted target water supply temperature so as to improve the heat exchange amount carried by water supply of the water channel system, in the process, the target water supply temperature of the water channel system is not the preset fixed temperature, but can be adapted to the change of the temperature adjustment requirement of the indoor space, the adjustment of the target water supply temperature of the water channel system can achieve the adjustment of the heat exchange amount output by the heat pump system to the water channel system, and the target water supply temperature of the water channel system can be adjusted according to a certain direction so as to increase the heat exchange amount provided by the heat pump system for the water channel system, and accordingly enable the current heat exchange amount to be released to the indoor space, the environment temperature of the indoor space to reach the set temperature quickly, and therefore the temperature adjustment efficiency of the indoor space and the indoor user comfort are improved.
Further, in this embodiment, the step of reducing the current target water supply temperature of the waterway system includes: the current target water supply temperature of the waterway system is reduced to a first preset value, wherein the first preset value is the lowest water temperature which can be reached by the waterway system, or the first preset value is larger than the lowest water temperature which can be reached by the waterway system and the temperature difference between the first preset value and the lowest water temperature is smaller than a first preset threshold.
The minimum water temperature can be a preset fixed parameter, and can also be a parameter determined according to the current operation condition of the heat pump system and/or the current operation condition of the waterway system, for example, the environment parameter of the environment where the heat pump system is located and the operation parameter of the water pump can be obtained, and the minimum water temperature is determined according to the environment parameter and the operation parameter.
In this embodiment, the target water supply temperature of the water path system is adjusted to the lowest water temperature or close to the lowest water temperature, so that the water supply temperature of the water path system under the adjustment of the heat pump system can be ensured to be low enough, and the heat pump system carries as much cold as possible to exchange heat with the indoor space, thereby improving the cooling efficiency of the indoor space.
In other embodiments, the temperature adjustment range is also determined according to the temperature difference between the first ambient temperature and the set temperature of the indoor space, and the current target water supply temperature of the waterway system is reduced according to the temperature adjustment range, so as to obtain the reduced target water supply temperature. When the number of the indoor spaces is more than one, the temperature difference between the first environment temperature corresponding to the more than one indoor space and the corresponding set temperature can be determined, the set temperatures corresponding to different indoor spaces can be different, the temperature adjustment range is determined according to the number relation (such as the proportional relation) between the more than one temperature difference, the current target water supply temperature of the waterway system is reduced according to the temperature adjustment range, and the reduced target water supply temperature is obtained. Specifically, the weight value corresponding to each indoor space can be determined according to the quantity relation, the temperature adjustment amplitude corresponding to the temperature difference corresponding to each indoor space is determined, the target temperature adjustment amplitude is calculated according to more than one temperature adjustment amplitude and the weight value corresponding to the temperature adjustment amplitude, the current target water supply temperature of the waterway system is reduced according to the target adjustment amplitude, and the reduced target water supply temperature is obtained.
Further, in this embodiment, the step of increasing the current target water supply temperature of the waterway system includes: and increasing the current target water supply temperature of the waterway system to a second preset value, wherein the second preset value is the highest water temperature which can be reached by the waterway system, or the second preset value is smaller than the highest water temperature which can be reached by the waterway system and the temperature difference between the second preset value and the highest water temperature is smaller than a second preset threshold.
The maximum water temperature can be a preset fixed parameter, and can also be a parameter determined according to the current operation condition of the heat pump system and/or the current operation condition of the waterway system, for example, the environment parameter of the environment where the heat pump system is located and the operation parameter of the water pump can be obtained, and the maximum water temperature is determined according to the environment parameter and the operation parameter.
In this embodiment, the target water supply temperature of the water path system is adjusted to the highest water temperature or close to the highest water temperature, so that the water supply temperature of the water path system under the adjustment of the heat pump system can be ensured to be high enough, and heat exchange is carried as much as possible with the indoor space, thereby improving the temperature rising efficiency of the indoor space.
In other embodiments, the temperature adjustment range is also determined according to a temperature difference between the first ambient temperature and the set temperature of the indoor space, and the current target water supply temperature is increased according to the temperature adjustment range, so that the increased target water supply temperature is obtained. When the number of the indoor spaces is more than one, the temperature difference between the first environment temperature corresponding to the more than one indoor space and the corresponding set temperature can be determined, the set temperatures corresponding to different indoor spaces can be different, the temperature adjustment range is determined according to the number relation (such as the proportional relation) between the more than one temperature difference, the current target water supply temperature of the waterway system is increased according to the temperature adjustment range, and the increased target water supply temperature is obtained. Specifically, the weight value corresponding to each indoor space can be determined according to the quantity relation, the temperature adjustment amplitude corresponding to the temperature difference corresponding to each indoor space is determined, the target temperature adjustment amplitude is calculated according to more than one temperature adjustment amplitude and the weight value corresponding to the temperature adjustment amplitude, the current target water supply temperature of the waterway system is increased according to the target adjustment amplitude, and the increased target water supply temperature is obtained. Based on the method, the heating requirements of different indoor spaces can be comprehensively considered, and the target water supply temperature after the waterway system is increased can simultaneously meet the heating efficiency of more than one space so as to meet the comfort requirements of users in different indoor spaces.
Further, based on the above embodiment, another embodiment of a control method of the environmental conditioning apparatus of the present application is proposed. In this embodiment, referring to fig. 4, after step S10, the method further includes:
step S11, determining a first temperature difference value between the first ambient temperature and a set temperature corresponding to the indoor space;
the set temperature is specifically a target value which is required to be reached by the corresponding indoor space under the regulation action of the environment regulating device. The set temperature may be a parameter set by the user, or may be a parameter determined by the environment adjusting device based on the monitored state parameter of the indoor space.
In this embodiment, the first temperature difference is an absolute value of a difference between the first ambient temperature and the set temperature. In other embodiments, the first temperature difference may also be a difference between the set temperature and the first ambient temperature; or the first temperature difference may be a difference between the first ambient temperature and the set temperature.
Executing S101 when the first ambient temperature is greater than the set temperature while the heat pump system is in the cooling mode; s101 is performed when the heat pump system is in the heating mode and the first ambient temperature is less than the set temperature.
And step S12, when the first temperature difference value is larger than a first preset temperature difference value, determining that the first environment temperature reaches the preset condition.
The first preset temperature difference is specifically a temperature difference critical value for distinguishing whether the load of the indoor space is excessive.
When the first temperature difference value is larger than a first preset temperature difference value, the load of the indoor space is indicated to be overlarge, and the heat exchange efficiency is required to be improved; when the first temperature difference value is smaller than or equal to a first preset temperature difference value, the load of the indoor space is not excessive, and the heat exchange efficiency is not required to be improved.
In this embodiment, the actual load of the indoor space is accurately represented by the first temperature difference value, based on this, when the actual load of the indoor space is too large, the target water supply temperature of the waterway system can be adjusted in time to improve the heat exchange amount output by the heat pump system, so that the heat exchange amount carried by water in the waterway system is increased to improve the heat exchange efficiency of the indoor space.
In other embodiments, when the heat pump system is in refrigeration operation, the first ambient temperature may also be determined to reach the preset condition when the first ambient temperature is greater than the first preset temperature; when the heat pump system is in heating operation, the first ambient temperature can be determined to not reach the preset condition when the first ambient temperature is smaller than the second preset temperature.
Further, in this embodiment, the step of determining that the first ambient temperature reaches the preset condition when the first temperature difference is greater than a first preset temperature difference includes:
step S121, when the number of the indoor spaces is more than one, determining a maximum temperature difference value among more than one first temperature difference values;
step S122, when the maximum temperature difference value is greater than the first preset temperature difference, determining that the first ambient temperature reaches the preset condition.
In this embodiment, when the environmental conditioning apparatus needs to condition the environmental temperature of more than one indoor space, when the maximum first temperature value in all indoor spaces is greater than the first preset temperature difference, the heat exchange amount output by the heat pump system is increased by adjusting the target water supply temperature of the waterway system.
Further, based on any one of the above embodiments, a further embodiment of a control method of the environmental conditioning apparatus of the present application is provided. In this embodiment, the target water supply temperature after the target temperature is defined as the target water supply temperature adjusted when the first ambient temperature reaches the preset condition, where the target temperature may include the first preset value or the second preset value, referring to fig. 5, after the step S20, further includes:
and step S30, when a second temperature difference value between the current second environment temperature of the indoor space and the set temperature corresponding to the indoor space is smaller than a second preset temperature difference value, or when the current water supply temperature of the waterway system reaches the target temperature, and when the current water supply temperature of the waterway system reaches the target temperature and lasts for a preset period of time, adjusting the target temperature and controlling the heat pump system to operate according to the adjusted target temperature so as to reduce the heat exchange quantity carried by water supply of the waterway system.
And when the number of the indoor spaces is more than one, when the second temperature difference value corresponding to the target space is smaller than a second preset temperature difference value, the current target water supply temperature of the waterway system is adjusted by taking the heat exchange quantity carried by water supply of the waterway system as a target.
The current water supply temperature of the waterway system can be obtained by acquiring the current detection data of the temperature sensor. The current water supply temperature of the waterway system reaches the target temperature specifically comprises: when the heat pump system is in refrigeration operation, the current water supply temperature of the waterway system is less than or equal to the target temperature; when the heat pump system is in heating operation, the current water supply temperature of the waterway system is greater than or equal to the target temperature.
The preset duration may be a preset fixed duration, or may be a duration determined according to the first temperature difference values corresponding to all the indoor spaces.
It should be noted that, here, the adjustment direction of the target temperature is opposite to the adjustment direction of the target water supply temperature when the first ambient temperature reaches the preset condition. Specifically, when the second temperature difference between the current second ambient temperature of the indoor space and the set temperature corresponding to the indoor space is smaller than a second preset temperature difference, or when the current water supply temperature of the waterway system reaches the target temperature, and when the current water supply temperature of the waterway system reaches the target temperature and lasts for a preset period of time, the heat pump system increases the target temperature and controls the heat pump system to operate according to the increased target temperature when in refrigeration operation, and reduces the target temperature and controls the heat pump system to operate according to the reduced target temperature when in heating operation.
In this embodiment, after the target water supply temperature is adjusted, if any condition is reached, it can be considered that the indoor space has higher heat exchange efficiency and does not have a lifting requirement, and the current target water supply temperature (i.e. the target temperature) of the waterway system is further adjusted to reduce the heat exchange amount output by the heat pump system, so that the indoor space heat exchange efficiency is ensured, and meanwhile, excessive refrigeration or heating of the indoor space is avoided, and the indoor user comfort is improved.
In other embodiments, a target time period may also be set after step S20, the target temperature may be adjusted, and the heat pump system may be controlled to operate according to the adjusted target temperature, so as to reduce the heat exchange amount carried by the water supply of the waterway system.
Further, the step of adjusting the target temperature and controlling the heat pump system to operate according to the adjusted target temperature so as to reduce the heat exchange amount carried by the water supply of the waterway system includes:
adjusting the target temperature according to a preset rate, and controlling the heat pump system to operate according to the adjusted target temperature until the adjusted target temperature reaches an initial temperature;
the initial temperature is the temperature before the target water supply temperature is not adjusted when the first ambient temperature reaches the preset condition.
The preset rate is specifically a rate when the target temperature is increased or decreased, and specifically, the preset rate is a temperature change value per unit time in the process of increasing or decreasing the target temperature. The preset rate may be a fixed rate set in advance, or may be a rate determined according to a second temperature difference value, wherein when the number of indoor spaces is more than one, the preset rate may be determined according to more than one second temperature difference value.
Specifically, when the preset speed is that the preset temperature value is adjusted every set time, the heat pump system can increase the target temperature according to the preset temperature value when in refrigeration operation, and control the heat pump system to operate according to the increased target temperature serving as the target water supply temperature of the waterway system, and when the increased target temperature is smaller than the initial temperature, the step of increasing the target temperature according to the preset temperature value is performed at intervals for a set time, until the increased target temperature is greater than or equal to the initial temperature; when the heat pump system is in heating operation, the target temperature can be reduced according to the preset temperature value, the heat pump system is controlled to operate according to the reduced target temperature serving as the target water supply temperature of the waterway system, and when the reduced target temperature is greater than the initial temperature, the step of reducing the target temperature according to the preset temperature value is carried out at intervals for a set period of time until the reduced target temperature is less than or equal to the initial temperature.
In this embodiment, the target water supply temperature of the water path system is adjusted to the initial temperature according to a certain rate, instead of directly switching the target water supply temperature to the initial temperature, so that shutdown caused by reliability problems in operation of the heat pump system due to direct switching is avoided, and stable operation of the heat pump system is ensured.
In addition, the embodiment of the invention also provides a storage medium, wherein the storage medium stores a control program of the environment adjusting device, and the control program of the environment adjusting device realizes the relevant steps of any embodiment of the control method of the environment adjusting device when being executed by a processor.
