Description

Technical Field

[0001] The present invention relates to the technical field of environmental equipment, and in particular to a control method for environmental conditioning equipment, an environmental conditioning equipment, and a storage medium. Background Art

[0002] In addition to traditional air conditioners, there are currently heat pump systems and water system environmental conditioning equipment to provide the required cooling or heat for indoor environmental regulation. The heat pump system can provide water carrying cooling or heat to the water system. The water flowing into the water system flows into the indoor environment for heat exchange to regulate the temperature of the indoor environment.

[0003] During heat pump system operation, a target water supply temperature is typically set. Based on the relationship between the actual measured water temperature supplied by the heat pump system to the water system and the target water supply temperature, the heat pump system's operation is regulated to ensure that the water supply temperature reaches the target. However, this target water supply temperature is typically manually set by the user or determined based on actual operating conditions when the system is powered on. This target water supply temperature remains fixed during operation, which can easily lead to insufficient heat pump system output capacity, slow indoor temperature rise or fall, and poor user comfort.

[0015] Optionally, after the step of obtaining the first ambient temperature of the indoor space regulated by the water system, the method further includes:

[0016] determining a first temperature difference between the first ambient temperature and a set temperature corresponding to the indoor space;

[0017] When the first temperature difference is greater than a first preset temperature difference, it is determined that the first ambient temperature meets the preset condition.

[0018] Optionally, when the first temperature difference is greater than a first preset temperature difference, the step of determining whether the first ambient temperature reaches the preset condition includes:

[0019] When the number of the indoor spaces is more than one, determining a maximum temperature difference value among the more than one first temperature difference values;

[0021] Optionally, after defining the target temperature as the target water supply temperature adjusted when the first ambient temperature reaches a preset condition, and adjusting the current target water supply temperature of the water system when the first ambient temperature reaches the preset condition, and controlling the operation of the heat pump system according to the adjusted target water supply temperature to increase the heat exchange capacity of the water supply of the water system, the method further includes:

[0022] 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 less than the second preset temperature difference, or when the current water supply temperature of the water system reaches the target temperature, when the current water supply temperature of the water system reaches the target temperature and lasts for a preset period of time, the target temperature is adjusted and the operation of the heat pump system is controlled according to the adjusted target temperature to reduce the heat exchange amount carried by the water supply of the water system.

At this time, the current target water supply temperature of the water system is adjusted, and the operation of the heat pump system is controlled based on the adjusted target water supply temperature to increase the heat exchange capacity of the water supply system. In this process, the target water supply temperature of the water system is no longer a preset fixed temperature, but can adapt to changes in the temperature regulation requirements of the indoor space. Adjusting the target water supply temperature of the water system can adjust the heat exchange capacity output by the heat pump system to the water system. Adjusting the target water supply temperature of the water system in a certain direction can increase the heat exchange capacity provided by the heat pump system to the water system, thereby allowing the water system to release more heat exchange capacity to the indoor space, allowing the ambient temperature of the indoor space to quickly reach the set temperature, thereby improving the temperature regulation efficiency of the indoor space and improving the comfort of indoor users.

[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] An embodiment of the present invention provides an environment adjustment device, specifically for adjusting the temperature of an indoor environment.

[0037] In the embodiment of the present invention, referring to Figure 1 and Figure 2The environmental conditioning device includes a heat pump system 2, a water system 3 connected to the heat pump system 2, and a control device 1. Both the heat pump system 2 and the water system 3 are connected to the control device 1. The heat pump system 2 is used to adjust the water supply temperature of the water system 3, and the water system 3 is used to adjust the indoor temperature. In this embodiment of the present invention, the water supply temperature of the water system 3 can be understood as the water outlet temperature of the heat pump system 2.

[0038] In this embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may also be a water source heat pump system, a ground source heat pump system, or a dual source heat pump system.

[0039] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop and a hot water exchange circuit. The refrigerant circulation loop includes a compressor, a first heat exchanger, a throttling device, and a second heat exchanger, and the second heat exchanger is heat-exchange-connected to the hot water exchange circuit. The heat pump system 2 can be a heat pump system with a single cooling function (i.e., the heat pump system has a cooling mode as an operating mode, and when turned on, the second heat exchanger is constantly in an evaporating state), a heat pump system with a single heating function (i.e., the heat pump system has a heating mode as an operating mode, and when turned on, the second heat exchanger is constantly in a condensing state), or a heat pump system with switching cooling and heating functions (i.e., the heat pump system has two operating modes, a cooling mode and a heating mode, and when turned on, the second heat exchanger can switch between an evaporating state and a condensing state).

[0040] The water system 3 includes a water circulation loop and a terminal heat exchange device located within the water circulation loop. The terminal heat exchange device may include a floor heating coil, a radiant panel, a fan coil, or a heat sink. The cooling or heating energy from the water in the water circulation loop is released to the indoor space at the terminal heat exchange device. There may be one or more terminal heat exchange devices, and these multiple terminal heat exchange devices may be located in different indoor spaces. Thus, the cooling or heating energy carried by the water in the water circulation loop can be used to regulate the ambient temperature of more than one indoor space.

[0041] The water circulation loop has a water inlet and a water outlet. The water inlet of the water circulation loop is connected with the outlet of the hot water exchange circuit, and the water outlet of the water circulation loop is connected with the inlet of the hot water exchange circuit.

[0042] During operation, heat pump system 2 absorbs the cooling or heat released by the second heat exchanger to form cold or hot water. The hot or cold water flowing out of the heat exchange branch enters the water circulation loop and flows to the terminal heat exchanger, releasing the cooling or heat to the indoor air to regulate the indoor temperature. After releasing the cooling or heat, the water re-enters the hot water exchange loop to exchange heat with the second heat exchanger. After this heat exchange, the water re-enters the water circulation loop to exchange heat, and this cycle repeats, enabling the environmental conditioning device to regulate the indoor temperature.

[0043] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The water in the heat exchange circuit absorbs the cold output by the second heat exchanger and its temperature drops to form cold water. The cold water enters the water circulation loop and flows to the terminal heat exchange equipment, releasing cold energy to the indoor space, and the ambient temperature of the indoor space drops.

[0044] When the heat pump system 2 is operating for heating, the second heat exchanger is in a condensing state. The water in the heat exchange circuit absorbs the heat output by the second heat exchanger and its temperature rises to form hot water. The hot water enters the water circulation loop and flows to the terminal heat exchange device, releasing heat to the indoor space, thereby increasing the ambient temperature of the indoor space.

[0045] Further, in this embodiment, referring to Figure 1 and Figure 2 ,in Figure 1 The arrow in the middle indicates the direction of water flow. The environmental conditioning device may also include a temperature sensor 4 , which is located at the outlet of the water exchange circuit or the inlet of the water circulation loop and is connected to the control device 1 . Temperature sensor 4 can be used to detect the actual water supply temperature of the water system 3 .

[0046] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to an environment detection module 5 provided in the indoor space, and the environment detection module 5 can detect the ambient temperature of the indoor space where it is located.

[0047] In the embodiment of the present invention, referring to Figure 2 The control device 1 of the environmental conditioning device includes a processor 1001 (e.g., a CPU), a memory 1002, a timer 1003, and the like. The various components of the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a non-volatile memory such as a disk drive. Alternatively, the memory 1002 can be a storage device independent of the processor 1001.

[0048] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0049] like Figure 2 As shown, the memory 1002 as a storage medium may include a control program of the environment adjustment device. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the environmental conditioning device stored in the memory 1002 and execute the relevant steps of the control method of the environmental conditioning device in the following embodiments.

[0050] An embodiment of the present invention further provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0051] Reference Figure 3 , an embodiment of a control method for an environmental conditioning device of the present application is proposed. In this embodiment, the control method for the environmental conditioning device includes:

[0052] Step S10, obtaining a first ambient temperature of the indoor space regulated by the water system;

[0053] The first ambient temperature can be specifically obtained by acquiring data detected by an environmental parameter module set in the indoor space.

[0054] The number of the first ambient temperatures here can be one or more than one. When there are more than one first ambient temperatures, the more than one ambient temperatures are detected at different times.

[0055] Specifically, the initial temperature of the target water supply temperature of the water system is obtained, the heat pump system is controlled to operate in cooling or heating mode according to the initial temperature, and step S10 is executed.

[0056] Step S20, when the first ambient temperature reaches a preset condition, adjust the current target water supply temperature of the water system, and control the operation of the heat pump system according to the adjusted target water supply temperature to increase the heat exchange capacity carried by the water supply of the water system.

[0057] The preset conditions are specifically conditions that the first ambient temperature must meet when the indoor space is overloaded. The preset conditions include a target temperature range that the first ambient temperature must meet, and may also include a target quantitative relationship or target magnitude relationship between the first ambient temperature and a preset temperature threshold.

[0058] When the first ambient temperature reaches a preset condition, it indicates that the current load of the indoor space is too large, and there is a need to further increase the temperature adjustment speed of the indoor space.

[0059] The direction of adjustment of the target water supply temperature of the water system can be determined based on the current operating mode of the heat pump system, with different operating modes corresponding to different target water supply temperature adjustment directions. In this embodiment, when the heat pump system is in cooling operation, the current target water supply temperature of the water system is reduced; when the heat pump system is in heating operation, the current target water supply temperature of the water system is increased. In other embodiments, when the heat pump system is a cooling-only system, the step of adjusting the current target water supply temperature of the water system can also be set by default to reducing the current target water supply temperature of the water system; when the heat pump system is a heating-only system, the step of adjusting the current target water supply temperature of the water system can also be set by default to increasing the current target water supply temperature of the water system.

[0060] Methods for adjusting the target water supply temperature may include: adjusting the current target water supply temperature of the water system to a preset target value, the target value being the adjusted target water supply temperature, and different operating modes corresponding to different target values; adjusting the current target water supply temperature of the water system according to a preset temperature adjustment value (such as a temperature adjustment ratio or a temperature adjustment amplitude, etc.) or a temperature adjustment value determined according to the actual operating conditions of the environmental control equipment (such as a temperature adjustment ratio or a temperature adjustment amplitude, etc.), and the obtained target value is used as the adjusted target water supply temperature; the target water supply temperature of the water system may also be adjusted according to a preset temperature adjustment rate, and the operation of the heat pump system may be controlled according to the adjusted target water supply temperature during the adjustment process.

[0061] After obtaining the adjusted target water supply temperature, the data detected by the above-mentioned temperature sensor can be read to obtain the current water supply temperature of the water system, and the current water supply temperature of the water system and the adjusted target water supply temperature can be determined to control the operation of the heat pump system. Specifically, when the heat pump system is in cooling operation, when the current water supply temperature of the water system is greater than the adjusted target water supply temperature, the heat pump system is controlled to operate to reduce the actual water supply temperature of the water system (such as increasing the operating frequency of the compressor, etc.); when the current water supply temperature of the water system is less than the adjusted target water supply temperature, the heat pump system is controlled to operate to increase the actual water supply temperature of the water system (such as reducing the operating frequency of the compressor, etc.). When the heat pump system is in heating operation, when the current water supply temperature of the water system is greater than the adjusted target water supply temperature, the heat pump system is controlled to operate to reduce the actual water supply temperature of the water system (such as reducing the operating frequency of the compressor, etc.); when the current water supply temperature is less than the adjusted target water supply temperature, the heat pump system is controlled to operate to increase the actual water supply temperature of the water system (such as increasing the operating frequency of the compressor, etc.). Based on this, it can be ensured that the water supply temperature of the water system can accurately reach the adjusted target water supply temperature, so that the heat exchange amount provided by the water system to the indoor space can accurately meet the actual load requirements of the indoor space.

[0062] An embodiment of the present invention provides a control method for an environmental conditioning device, based on the environmental conditioning device including a heat pump system and a water system connected to the heat pump system. When a first ambient temperature of an indoor space regulated by the water system reaches a preset condition, it is determined that the difference between the ambient temperature of the indoor space and the set temperature is large. In this case, the current target water supply temperature of the water system is adjusted, and the operation of the heat pump system is controlled based on the adjusted target water supply temperature to increase the heat exchange capacity of the water supply system. In this process, the target water supply temperature of the water system is no longer a preset fixed temperature, but can adapt to changes in the temperature regulation requirements of the indoor space. Adjusting the target water supply temperature of the water system adjusts the heat exchange capacity output by the heat pump system to the water system. Adjusting the target water supply temperature of the water system in a certain direction can increase the heat exchange capacity provided by the heat pump system to the water system, thereby allowing the water system to release more heat to the indoor space, quickly bringing the ambient temperature of the indoor space to the set temperature. This improves the temperature regulation efficiency of the indoor space and improves the comfort of indoor users.

[0063] Furthermore, in this embodiment, the step of reducing the current target water supply temperature of the water system includes: reducing the current target water supply temperature of the water system to a first preset value, the first preset value being the lowest water temperature that the water system can reach, or the first preset value being greater than the lowest water temperature that the water system can reach and the temperature difference with the lowest water temperature is less than a first preset threshold.

[0064] The minimum water temperature here can be a pre-set fixed parameter, or it can be a parameter determined according to the current operating conditions of the heat pump system and / or the current operating conditions of the water system. For example, the environmental parameters of the environment in which the heat pump system is located and the operating parameters of the water pump can be obtained, and the minimum water temperature here can be determined based on the environmental parameters and operating parameters.

[0065] In this embodiment, by adjusting the target water supply temperature of the water system to the minimum water temperature or close to the minimum water temperature, it can be ensured that the heat pump system regulates the water supply temperature of the sewer system to be low enough to carry as much cold energy as possible for heat exchange with the indoor space, thereby improving the cooling efficiency of the indoor space.

[0066] In other embodiments, the temperature adjustment amplitude is also determined based on 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 water system is reduced according to the temperature adjustment amplitude to obtain the reduced target water supply temperature. When there are more than one indoor spaces, the temperature difference between the first ambient temperature and the corresponding set temperature corresponding to more than one indoor space can be determined, and the set temperatures corresponding to different indoor spaces may be different. The temperature adjustment amplitude is determined based on the quantitative relationship (for example, a proportional relationship) between the more than one temperature differences, and the current target water supply temperature of the water system is reduced according to the temperature adjustment amplitude to obtain the reduced target water supply temperature. Specifically, the weight value corresponding to each indoor space can be determined based on the quantitative relationship, and the temperature adjustment amplitude corresponding to the temperature difference corresponding to each indoor space can be determined. The target temperature adjustment amplitude is calculated based on more than one temperature adjustment amplitude and its corresponding weight value, and the current target water supply temperature of the water system is reduced according to the target adjustment amplitude to obtain the reduced target water supply temperature.

[0067] Furthermore, in this embodiment, the step of increasing the current target water supply temperature of the water system includes: increasing the current target water supply temperature of the water system to a second preset value, the second preset value is the highest water temperature that the water system can reach, or the second preset value is lower than the highest water temperature that the water system can reach and the temperature difference with the highest water temperature is lower than a second preset threshold.

[0068] The maximum water temperature here can be a pre-set fixed parameter, or it can be a parameter determined according to the current operating conditions of the heat pump system and / or the current operating conditions of the water system. For example, the environmental parameters of the environment in which the heat pump system is located and the operating parameters of the water pump can be obtained, and the maximum water temperature here can be determined based on the environmental parameters and operating parameters.

[0069] In this embodiment, by adjusting the target water supply temperature of the water system to the maximum water temperature or close to the maximum water temperature, it can be ensured that the heat pump system regulates the water supply temperature of the sewer system to be high enough to carry as much heat as possible for heat exchange with the indoor space, thereby improving the heating efficiency of the indoor space.

[0070] In other embodiments, a temperature adjustment range is also determined based on the temperature difference between the first ambient temperature and the set temperature of the indoor space. The current target water supply temperature is increased by the temperature adjustment range to obtain an increased target water supply temperature. When there are more than one indoor space, the temperature difference between the first ambient temperature and the corresponding set temperature can be determined for more than one indoor space. Different indoor spaces can have different set temperatures. The temperature adjustment range is determined based on a quantitative relationship (e.g., a proportional relationship) between the more than one temperature differences. The current target water supply temperature of the water system is increased by the temperature adjustment range to obtain an increased target water supply temperature. Specifically, a weight value corresponding to each indoor space can be determined based on the quantitative relationship. The temperature adjustment range corresponding to the temperature difference corresponding to each indoor space is determined. The target temperature adjustment range is calculated based on the more than one temperature adjustment range and their corresponding weight values. The current target water supply temperature of the water system is increased by the target adjustment range to obtain an increased target water supply temperature. Based on this, the heating requirements of different indoor spaces can be comprehensively considered to ensure that the increased target water supply temperature of the water system can simultaneously meet the heating efficiency of more than one space, thereby satisfying the comfort needs of users in different indoor spaces.

[0071] Furthermore, based on the above embodiment, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, referring to Figure 4 After step S10, the method further includes:

[0072] Step S11, determining a first temperature difference between the first ambient temperature and a set temperature corresponding to the indoor space;

[0073] The set temperature is specifically the target value that the ambient temperature of the corresponding indoor space should reach under the regulation of the environmental conditioning device. The set temperature can be a parameter set by the user or determined by the environmental conditioning device based on the state parameters of the indoor space monitored by the environmental conditioning device.

[0074] In this embodiment, the first temperature difference is the absolute value of the difference between the first ambient temperature and the set temperature. In other embodiments, the first temperature difference may also be the difference between the set temperature and the first ambient temperature; or the first temperature difference may also be the difference between the first ambient temperature and the set temperature.

[0075] When the heat pump system is in cooling mode, S101 is executed when the first ambient temperature is greater than the set temperature; when the heat pump system is in heating mode, S101 is executed when the first ambient temperature is less than the set temperature.

[0076] Step S12: When the first temperature difference is greater than a first preset temperature difference, it is determined that the first ambient temperature reaches the preset condition.

[0077] The first preset temperature difference is specifically a temperature difference critical value used to distinguish whether the load of the indoor space is too large.

[0078] When the first temperature difference value is greater than the first preset temperature difference, it indicates that the load of the indoor space is too large and there is a need to improve the heat exchange efficiency; when the first temperature difference value is less than or equal to the first preset temperature difference, it indicates that the load of the indoor space is not too large and there is no need to improve the heat exchange efficiency.

[0079] 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 water system can be adjusted in time to increase the heat exchange output of the heat pump system, thereby increasing the heat exchange capacity carried by the water in the water system to improve the heat exchange efficiency of the indoor space.

[0080] In other embodiments, when the heat pump system is in cooling operation, it may be determined that the first ambient temperature meets the preset condition when the first ambient temperature is greater than the first preset temperature; when the heat pump system is in heating operation, it may be determined that the first ambient temperature does not meet the preset condition when the first ambient temperature is less than the second preset temperature.

[0081] Furthermore, in this embodiment, when the first temperature difference is greater than a first preset temperature difference, the step of determining whether the first ambient temperature reaches the preset condition includes:

[0082] Step S121: when the number of the indoor spaces is more than one, determining a maximum temperature difference value among the more than one first temperature difference values;

[0083] Step S122: When the maximum temperature difference is greater than the first preset temperature difference, it is determined that the first ambient temperature meets the preset condition.

[0084] In this embodiment, when the environmental conditioning device needs to adjust the ambient 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 output by the heat pump system is increased by adjusting the target water supply temperature of the water system.

[0085] Furthermore, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, the target temperature is defined as the target water supply temperature adjusted when the first ambient temperature reaches the preset condition. The target temperature may include the first preset value or the second preset value mentioned above. Figure 5 After step S20, the method further includes:

[0086] Step S30, 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 less than the second preset temperature difference, or when the current water supply temperature of the water system reaches the target temperature, when the current water supply temperature of the water system reaches the target temperature and lasts for a preset time, adjust the target temperature and control the operation of the heat pump system according to the adjusted target temperature to reduce the heat exchange amount carried by the water supply of the water system.

[0087] Among them, when there are more than one indoor spaces, when the second temperature difference value corresponding to the above target space is less than the second preset temperature difference, the current target water supply temperature of the water system is adjusted with the goal of reducing the heat exchange amount carried by the water supply of the water system.

[0088] The current water supply temperature of the water system can be obtained by obtaining the data currently detected by the temperature sensor. The current water supply temperature of the water system reaching the target temperature specifically includes: when the heat pump system is in cooling operation, the current water supply temperature of the water 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 water system is greater than or equal to the target temperature.

[0089] The preset duration may be a fixed duration set in advance, or may be a duration determined according to the first temperature difference values ​​corresponding to all indoor spaces.

[0090] It should be noted that the target temperature adjustment direction here is opposite to the target water supply temperature adjustment direction 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 corresponding set temperature of the indoor space is less than the second preset temperature difference, or when the current water supply temperature of the water system reaches the target temperature, or when the current water supply temperature of the water system reaches the target temperature and remains at the target temperature for a preset period of time, the heat pump system increases the target temperature when in cooling operation and controls operation according to the increased target temperature; and decreases the target temperature when in heating operation and controls operation according to the decreased target temperature.

[0091] In this embodiment, after adjusting the target water supply temperature, if any of the above conditions is met, it can be considered that the heat exchange efficiency of the indoor space is relatively high and there is no need to increase it. At this time, the current target water supply temperature of the water system (that is, the target temperature) is further adjusted to reduce the heat exchange output by the heat pump system, thereby ensuring the heat exchange efficiency of the indoor space while avoiding excessive cooling or heating of the indoor space, thereby improving the comfort of indoor users.

[0092] In other embodiments, the target temperature may be adjusted at target time intervals after step S20 and the heat pump system may be controlled to operate according to the adjusted target temperature to reduce the heat exchange amount carried by the water supply of the water system.

[0093] Furthermore, the step of adjusting the target temperature and controlling the operation of the heat pump system according to the adjusted target temperature to reduce the amount of heat exchange carried by the water supply of the water system includes:

[0094] Adjusting the target temperature according to a preset rate, and controlling the operation of the heat pump system according to the adjusted target temperature until the adjusted target temperature reaches an initial temperature;

[0095] The initial temperature is the temperature before the target water supply temperature is adjusted when the first ambient temperature reaches the preset condition.

[0096] The preset rate is specifically the rate at which the target temperature is increased or decreased. Specifically, the preset rate is the temperature change per unit time during the increase or decrease of the target temperature. The preset rate can be a pre-set fixed rate or a rate determined based on the second temperature difference. If there are more than one indoor spaces, the preset rate can be determined based on more than one second temperature difference.

[0097] Specifically, when the preset rate is to adjust the preset temperature value every set time, when the heat pump system is in cooling operation, the target temperature can be increased according to the preset temperature value, and the heat pump system operation can be controlled according to the increased target temperature as the target water supply temperature of the water system. When the increased target temperature is lower than the initial temperature, the interval set time returns to the step of increasing the target temperature according to the preset temperature value 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, and the heat pump system operation can be controlled according to the reduced target temperature as the target water supply temperature of the water system. When the reduced target temperature is higher than the initial temperature, the interval set time returns to the step of reducing the target temperature according to the preset temperature value until the reduced target temperature is less than or equal to the initial temperature.

[0098] In this embodiment, the target water supply temperature of the water system is adjusted to the initial temperature at a certain rate, rather than directly switching the target water supply temperature to the initial temperature. This helps to avoid reliability problems in the operation of the heat pump system and cause shutdown due to direct switching, thereby ensuring stable operation of the heat pump system.

[0099] In addition, an embodiment of the present invention further proposes a storage medium on which a control program for an environmental conditioning device is stored. When the control program for the environmental conditioning device is executed by a processor, the relevant steps of any embodiment of the control method for the environmental conditioning device are implemented.
