[0051] The environmental control system provided in this application, employing the control method of the environmental control system in the following embodiments, can solve the technical problem of how to ensure indoor user comfort while saving system energy consumption and costs. Compared with the prior art, the beneficial effects of the environmental control system provided in this application are the same as the beneficial effects of the control method of the environmental control system provided in the following embodiments, and other technical features of this environmental control system are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0052] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control system capable of performing the above functions. The following description uses an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0053] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0054] In this embodiment, the control method of the environmental control system includes steps S10~S20: Step S10: Obtain the current electricity price period and the current outdoor temperature status information of the environmental control system; Electricity pricing periods may include peak electricity periods (times when electricity consumption is at its highest) and / or off-peak electricity periods (times when electricity consumption is at its lowest). The electricity price during peak hours is higher than the electricity price during off-peak hours. In this embodiment, the electricity price during either peak or off-peak hours is constant. In other embodiments, the electricity price during peak and / or off-peak hours may be set differently for each time period.

[0055] Temperature status information indicates the energy efficiency and heat exchange requirements of the environmental control system. Temperature status information may include the detected outdoor temperature value or outdoor temperature change parameters (rate of change and / or trend, etc.) under the current conditions.

[0056] In this embodiment, the peak-valley electricity saving function in the environmental control system is enabled when step S10 is executed. This function can be enabled in response to user commands.

[0057] Step S20: Adjust the set temperature of the environmental control system according to the electricity price period and the temperature status information, and control the operation of the environmental control system according to the adjusted set temperature.

[0058] The set temperature may include the system temperature itself, which is related to indoor temperature regulation during the operation of the environmental control system, and / or the target temperature that the indoor ambient temperature needs to reach. The initial value of the set temperature may be the user's set temperature. In this embodiment, the set temperature includes the set indoor temperature corresponding to the indoor space where the terminal device is located and / or the set refrigerant temperature of the refrigerant circulation system.

[0059] Different electricity price periods and different temperature status information correspond to different set temperatures or set temperature adjustment methods.

[0060] In one implementation, a target correspondence can be obtained between temperature status information and set temperature or set temperature adjustment method based on the electricity price period. Different electricity price periods correspond to different target correspondences. Based on the target correspondence, the target set temperature corresponding to the temperature status information can be determined, and the environmental control system can be operated according to the target set temperature. Alternatively, based on the target correspondence, the target adjustment method of the set temperature corresponding to the temperature status information can be determined, the set temperature can be adjusted according to the target adjustment method, and the environmental control system can be operated according to the adjusted set temperature.

[0061] In another implementation, the reference temperature range for the set temperature can be determined based on the electricity price period. Within the reference temperature range, the set temperature can be adjusted according to the temperature status information, and the environmental regulation system can be controlled to operate based on the adjusted set temperature.

[0062] In one implementation, during the operation of the environmental regulation system controlled according to the adjusted set indoor temperature, the current indoor temperature of the space where the indoor terminal equipment is located can be obtained, and the operation of the environmental regulation system can be controlled according to the temperature difference between the current indoor temperature and the set indoor temperature. In this embodiment, the target refrigerant temperature of the refrigerant circulation system is adjusted according to the temperature difference, and the operation of the heat pump system is controlled according to the adjusted target refrigerant temperature (at least one of the following: compressor frequency, electronic expansion valve opening, fan speed corresponding to the first heat exchanger, etc.) and / or the operation of the refrigerant circulation system is controlled according to the adjusted target refrigerant temperature (at least one of the following: control valve opening, operating parameters of the refrigerant circulation module, etc.). In this embodiment, the target refrigerant temperature may include the target value of the outlet liquid temperature of the heat exchange module. For example, when the heat pump system is operating in heating mode, if the temperature difference between the set indoor temperature and the current indoor temperature is less than a preset temperature difference, the first refrigerant temperature is determined as the target refrigerant temperature; if the temperature difference between the set indoor temperature and the current indoor temperature is greater than or equal to the preset temperature difference, the second refrigerant temperature is determined as the target refrigerant temperature, and the second refrigerant temperature is greater than the first refrigerant temperature.

[0063] In another implementation, during the operation of the environmental regulation system controlled according to the adjusted set refrigerant temperature, the current refrigerant temperature of the refrigerant circulation system is used to control the operation of the environmental regulation system based on the temperature difference between the current refrigerant temperature and the set refrigerant temperature. In this embodiment, the operating parameters of the heat pump system (compressor frequency, electronic expansion valve opening, fan speed corresponding to the first heat exchanger, etc., at least one) and / or the operating parameters of the refrigerant circulation system (control valve opening, refrigerant circulation module operating parameters, etc., at least one) are adjusted based on the temperature difference. In this embodiment, the set refrigerant temperature may include the target value of the outlet liquid temperature of the heat exchange module. For example, when the heat pump system is operating in heating mode, if the temperature difference between the set refrigerant temperature and the current refrigerant temperature is less than a preset temperature difference, the control valve corresponding to the indoor terminal device is closed; if the temperature difference between the set refrigerant temperature and the current refrigerant temperature is greater than or equal to the preset temperature difference, the control valve corresponding to the indoor terminal device is opened.

[0064] In this embodiment, during step S30, the heat pump system operates in heating mode, and the indoor terminal equipment is in heating mode.

[0065] This embodiment provides a control method for an environmental control system. This method combines electricity price time information and outdoor temperature information to adjust the set temperature of the environmental control system. The set temperature during the operation of the environmental control system is no longer fixed. The electricity price time information reflects the cost during system operation, and the temperature information reflects the energy efficiency and heat exchange requirements of the system. Based on this, the set temperature during the operation of the environmental control system can be set to adapt to the actual cost and energy efficiency of the system, thereby ensuring that the system can meet the comfort of indoor users while saving energy consumption and costs.

[0066] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the temperature status information includes the outdoor temperature, and the step of adjusting the set temperature of the environmental control system according to the electricity price period and the temperature status information, and controlling the operation of the environmental control system according to the adjusted set temperature includes: When the electricity price period is a low-temperature period, or when the electricity price period is a low-temperature period and the current time meets the first preset condition, the set temperature is adjusted according to the outdoor temperature using the corresponding adjustment method. The environmental regulation system is then controlled to operate according to the adjusted set temperature. The first preset condition includes the interval between the current time and the end time of the low-temperature period being greater than a first duration.

[0067] In this embodiment, the temperature during off-peak hours shows a decreasing trend.

[0068] The first duration can be a pre-set fixed duration, or it can be a duration determined according to the actual situation. For example, the first duration can be determined based on the interval between the moment when the indoor terminal equipment starts heating in response to the user's command during the peak power period and the end time of the off-peak power period in historical data, so as to ensure that the user has enough heating when using the equipment during the peak power period.

[0069] Determine the temperature range of the outdoor temperature, and adjust the setpoint temperature accordingly based on the temperature range (e.g., dynamically adjust the setpoint temperature based on target parameters, maintain the setpoint temperature at the target temperature, or adjust the setpoint temperature within the target temperature range, etc.). The adjusted setpoint temperature is positively correlated with the outdoor temperature; that is, the higher the outdoor temperature, the greater the system energy efficiency, and the higher the adjusted setpoint temperature, resulting in higher system heat output.

[0070] In this embodiment, the outdoor temperature accurately reflects the system's energy efficiency. Therefore, adjusting the set temperature according to the outdoor temperature during off-peak hours is beneficial for effectively utilizing the electricity during off-peak hours to store heat for indoor temperature regulation during peak hours. This ensures indoor comfort while saving overall system energy consumption and costs, and effectively improves system operating efficiency. Specifically, the first preset condition indicates that the time before the peak electricity period is relatively long, and the heat storage demand is low. In this case, adjusting the set temperature according to the outdoor temperature helps ensure heating comfort during off-peak hours while saving system energy consumption and costs.

[0071] In other embodiments, if the outdoor ambient temperature first decreases and then increases or first increases and then decreases during off-peak electricity hours, the set temperature can be adjusted according to the outdoor temperature and its changing trend. Alternatively, when the environmental control system is currently operating during off-peak electricity hours, it can maintain operation at a target set temperature higher than the user-set temperature.

[0072] In one feasible implementation, the set temperature includes the set indoor temperature of the indoor terminal device and / or the set refrigerant temperature of the refrigerant circulation system. The set indoor temperature is a target value set by the user for the temperature of the indoor space where the indoor terminal device is located. The set refrigerant temperature can be a target value set by the user for the temperature of the refrigerant in the refrigerant circulation system or a target value for the refrigerant temperature determined based on the set indoor temperature.

[0073] The steps of adjusting the set temperature according to the outdoor temperature using a corresponding adjustment method, and controlling the operation of the environmental control system according to the adjusted set temperature include: When the outdoor temperature is greater than or equal to a first preset temperature, the set indoor temperature and / or the set refrigerant temperature are increased; the operation of the environmental control system is controlled according to the increased set indoor temperature and / or the increased set refrigerant temperature; when the environmental control system operates to meet a first condition, the current set indoor temperature of the indoor terminal device and / or the current set refrigerant temperature of the refrigerant circulation system are decreased; the operation of the environmental control system is controlled according to the decreased set indoor temperature and / or the decreased set refrigerant temperature.

[0074] First preset temperature (e.g.) Figure 5 T in out，1 This is used to differentiate the energy efficiency of the environmental control system during off-peak electricity hours. When the outdoor temperature is greater than or equal to the first preset temperature, it indicates that the system energy efficiency is at a high level.

[0075] The indoor temperature is increased based on a first temperature adjustment value, and / or the refrigerant temperature is increased based on a second temperature adjustment value. The first and / or second temperature adjustment values ​​can be preset fixed values, or values ​​determined based on the actual operation of the environmental control system. For example, the first and / or second temperature adjustment values ​​can be determined based on the interval between the current time and the end time of the current time period, etc.

[0076] For example, if the indoor temperature is set to TS and the refrigerant temperature is set to TWS, then the increased indoor temperature setting is TS+△T1 and the increased refrigerant temperature setting is TWS+△T2.

[0077] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the increased set indoor temperature and / or the increased set refrigerant temperature. The control method is the same as described in the above embodiment and will not be repeated here.

[0078] The first condition indicates that the system's heat storage capacity reaches the target heat storage capacity after increasing the set indoor temperature and / or the set refrigerant temperature. In this embodiment, the first condition includes at least one of the following: the indoor temperature of the indoor space where the indoor terminal device is located reaches the increased set indoor temperature; the duration of operation of the environmental control system under the control of the increased set indoor temperature and / or the increased set refrigerant temperature reaches a preset duration. In other embodiments, the first condition may also include receiving a cooling command input by the user, or the first condition may include the operating time of the environmental control system during the first off-peak or peak electricity storage period reaching the target duration, etc.

[0079] The reduction range of the set indoor temperature and / or set refrigerant temperature can be a preset fixed value, or a value determined according to the actual operation of the environmental control system, such as the time interval between the current time and the end time of the current time period.

[0080] The reduced indoor temperature setting is less than or equal to the original indoor temperature setting, and the reduced refrigerant temperature setting is less than or equal to the original refrigerant temperature setting.

[0081] In this embodiment, the current set indoor temperature is reduced to the previous set indoor temperature, that is, reduced from TS+△T1 to TS, and the current set refrigerant temperature is reduced to less than the previous set refrigerant temperature, that is, reduced from TWS+△T2 to TWS-△T3.

[0082] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the reduced set indoor temperature and / or the reduced set refrigerant temperature. The control method is the same as described in the above embodiment and will not be repeated here.

[0083] In this embodiment, through the above method, the system is currently in the free heat storage period during off-peak electricity hours (e.g., Figure 5 When the system is in operation, it can first store heat for a period of time and then stop storing heat or reduce the amount of heat stored, thereby ensuring comfort while reducing the energy consumption and cost required for continuous heat storage. The system can find the lowest temperature that meets indoor comfort through dynamic adjustment, thereby further reducing energy consumption and cost.

[0084] In other embodiments, after increasing the set temperature, the environmental control system can be maintained at the increased set temperature until the environmental control system enters the peak power period, or the outdoor temperature is lower than the first preset temperature, or the outdoor temperature is greater than or equal to the first preset temperature and the duration reaches the target duration, etc.

[0085] In one implementation, after the step of controlling the operation of the environmental control system based on the reduced set indoor temperature and / or the reduced set refrigerant temperature, the method further includes: If the indoor temperature of the indoor space where the indoor terminal device is located is less than or equal to the reduced set indoor temperature, return to the steps of increasing the set indoor temperature and / or increasing the set refrigerant temperature.

[0086] In this embodiment, adjusting the set temperature of the environmental control system based on the temperature fluctuations of the indoor space helps ensure that the system can meet the indoor heat exchange needs with the lowest possible heat output, thereby ensuring indoor comfort while further saving the system's energy consumption and costs.

[0087] In one feasible embodiment, the step of controlling the operation of the environmental conditioning system according to the adjusted set temperature includes: maintaining the operation of the environmental conditioning system at the set indoor temperature and / or the set refrigerant temperature when the outdoor temperature is lower than the first preset temperature; or, maintaining the operation of the environmental conditioning system at the set indoor temperature when the outdoor temperature is lower than the first preset temperature; adjusting the set refrigerant temperature according to the temperature difference between the set indoor temperature and the indoor temperature of the space where the indoor terminal device is located, and controlling the operation of the environmental conditioning system according to the adjusted set refrigerant temperature.

[0088] When the heat pump system is in heating mode, if the temperature difference between the set indoor temperature and the current indoor temperature is less than the preset temperature difference, the first refrigerant temperature is determined as the target refrigerant temperature; if the temperature difference between the set indoor temperature and the current indoor temperature is greater than or equal to the preset temperature difference, the second refrigerant temperature is determined as the target refrigerant temperature, and the second refrigerant temperature is greater than the first refrigerant temperature.

[0089] In this embodiment, if the outdoor temperature is lower than the first preset temperature, it indicates that the system energy efficiency is low, and the system can be considered to be in a period of off-peak electricity and non-heat storage (e.g., Figure 5 In this case, maintaining the user-set indoor temperature control system is beneficial for effectively meeting the comfort needs of indoor users. Alternatively, while maintaining the user-set indoor temperature control system, the system can automatically adjust the set refrigerant temperature based on the temperature difference between the indoor temperature and the set indoor temperature to control the system operation, which is beneficial for effectively improving the comfort of indoor users.

[0090] In other embodiments, if the outdoor temperature is lower than the first preset temperature during off-peak hours, the set indoor temperature and / or the set refrigerant temperature can be adjusted according to the indoor temperature and / or the outdoor temperature, and the operation of the environmental control system can be controlled according to the adjusted set indoor temperature and / or set refrigerant temperature.

[0091] In one feasible embodiment, after the step of obtaining the current electricity price period of the environmental control system, the method further includes: if the electricity price period is a low-price period and the first preset condition is not met at the current time, increasing the set indoor temperature and / or increasing the set refrigerant temperature; and maintaining the operation of the environmental control system at the increased set indoor temperature and / or the increased set refrigerant temperature.

[0092] In this embodiment, the increase in the set indoor temperature is greater than or equal to the increase in the set indoor temperature when the outdoor temperature during off-peak hours is greater than or equal to the first preset temperature, and the increase in the set refrigerant temperature is greater than or equal to the increase in the set refrigerant temperature when the outdoor temperature during off-peak hours is greater than or equal to the first preset temperature.

[0093] In this embodiment, the increase in the indoor temperature and / or the refrigerant temperature can be a pre-set fixed parameter, or it can be a parameter determined according to the actual operating conditions, such as the increase value determined according to the current outdoor ambient temperature, etc.

[0094] When the electricity price period is a low-voltage period and the first preset condition is not met at the current time, the set temperature of the environmental control system is greater than the set temperature of the environmental control system when the electricity price period is a low-voltage period and the first preset condition is met at the current time. When the set temperature is a variable temperature, the set temperature of the environmental control system here refers to the average value of the set temperature under the corresponding conditions.

[0095] In this embodiment, the forced heat storage period (e.g., before the end of the off-peak electricity period, i.e. before the start of the peak electricity period) can be guaranteed by the above method. Figure 5It can store enough heat to ensure thermal comfort during peak electricity periods, effectively reducing the system's heating output when electricity prices are high, thus ensuring indoor comfort while saving system operating costs.

[0096] In other embodiments, if the first preset condition is not met at the current time during off-peak hours, the set indoor temperature can be adjusted according to the outdoor ambient temperature and / or the indoor ambient temperature within a temperature range greater than the user-set indoor temperature, and / or the set refrigerant temperature can be adjusted according to the outdoor ambient temperature and / or the indoor ambient temperature within a temperature range greater than the user-set refrigerant temperature, etc.

[0097] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the temperature status information includes the outdoor temperature and the outdoor temperature change trend. The step of adjusting the set temperature of the environmental control system according to the electricity price period and the temperature status information, and controlling the operation of the environmental control system according to the adjusted set temperature includes: When the electricity price period is a peak electricity period or when the electricity price period is a peak electricity period and the current time meets the second preset condition, the set temperature is adjusted according to the outdoor temperature and the outdoor temperature change trend, and the environmental control system is controlled to operate according to the adjusted set temperature. The second preset condition includes that the interval between the current time and the end time of the peak power period is longer than a second duration.

[0098] In this embodiment, the outdoor ambient temperature during peak power hours shows a trend of increasing and then decreasing.

[0099] The second duration can be a pre-set fixed duration, or it can be determined according to the actual situation, such as the total duration of the off-peak electricity period.

[0100] Different outdoor temperatures and different trends in outdoor temperature change correspond to different adjustment methods (e.g., dynamically adjusting the set temperature based on target parameters, maintaining the set temperature at the corresponding target temperature, or adjusting the set temperature within the target temperature range, etc.) and / or a target set temperature. In this embodiment, the target correspondence between the outdoor temperature and the adjustment method or target set temperature is determined based on the outdoor temperature change trend. Different outdoor temperature change trends result in different target correspondences. Based on this target correspondence, the target adjustment method corresponding to the current outdoor temperature is determined. The set temperature is adjusted according to the target adjustment method or adjusted to the target set temperature. The environmental regulation system is then controlled to operate based on the adjusted set temperature.

[0101] In this embodiment, the outdoor temperature accurately reflects the system's energy efficiency, and changes in outdoor temperature reflect changes in system energy efficiency and heat exchange demand. Therefore, adjusting the set temperature according to the outdoor temperature and its changing trend during peak power periods helps to increase the heat exchange capacity of indoor terminal equipment during peak power periods, meeting indoor comfort requirements without being excessive. This helps to ensure indoor comfort while saving energy consumption and costs during peak power periods, thus improving system energy efficiency. The second preset condition indicates that the time remaining before the end of the peak power period is relatively long, resulting in lower heat storage demand. In this case, adjusting the set temperature according to the outdoor temperature helps to ensure heating comfort during peak power periods while saving system energy consumption and costs.

[0102] In other embodiments, the indoor temperature and / or the refrigerant temperature can also be adjusted according to the adjustment method corresponding to the current outdoor temperature during peak power periods.

[0103] In one feasible implementation, the set temperature includes the set indoor temperature of the indoor terminal device and / or the set refrigerant temperature of the refrigerant circulation system. The set indoor temperature is a target value set by the user for the temperature of the indoor space where the indoor terminal device is located. The set refrigerant temperature can be a target value set by the user for the temperature of the refrigerant in the refrigerant circulation system or a target value for the refrigerant temperature determined based on the set indoor temperature.

[0104] The steps of determining the corresponding adjustment method based on the outdoor temperature and its changing trend, adjusting the set temperature, and controlling the operation of the environmental control system based on the adjusted set temperature include: When the outdoor temperature shows an upward trend and is less than the second preset temperature, or when the outdoor temperature shows a downward trend and is less than the first preset temperature, the environmental control system is maintained at the set indoor temperature and / or the set refrigerant temperature. Wherein, the second preset temperature (e.g.) Figure 5 T in out，2 () is greater than the first preset temperature.

[0105] The first preset temperature is the critical temperature used to distinguish between high and low system energy efficiency, and the second preset temperature is the temperature at which the system is at its highest energy efficiency.

[0106] In this embodiment, during the peak power period, the outdoor temperature shows an upward trend but has not yet reached the system's maximum energy efficiency. This can be considered the initial stage of peak power, and the current period can be regarded as the non-heat storage period of peak power (e.g. Figure 5During the off-peak electricity period (non-heat storage period), when electricity prices are higher and the stored heat from the off-peak period can be used to assist in regulating the indoor temperature, the system controls the temperature according to the user-set indoor temperature and / or the set refrigerant temperature. This helps ensure indoor comfort while saving system costs and energy consumption. During the peak electricity period, when the outdoor temperature is lower than the first preset temperature and the trend is downward, it indicates that the system's energy efficiency is lower and the indoor heating demand is smaller. In this case, the system controls the temperature according to the user-set indoor temperature and / or the set refrigerant temperature, which helps ensure indoor comfort while saving system costs and energy consumption, and effectively improves system energy efficiency.

[0107] In other embodiments, when the outdoor temperature shows an upward trend and is less than a second preset temperature, or when the outdoor temperature shows a downward trend and is less than a first preset temperature, the set indoor temperature and / or the set refrigerant temperature can be adjusted according to the indoor temperature and / or the outdoor temperature, and the operation of the environmental control system can be controlled according to the adjusted set indoor temperature and / or set refrigerant temperature.

[0108] In one feasible implementation, after the step of obtaining the current electricity price period of the environmental control system, the method further includes: If the electricity price period is a peak electricity period and the second preset condition is not met at the current time, the environmental control system shall be maintained at the set indoor temperature and / or the set refrigerant temperature.

[0109] In this embodiment, during a period of time before the end of the peak power period (e.g. Figure 5 The non-heat storage period before the end of the peak power period indicates that the outdoor ambient temperature is low, the indoor heating demand is low and the energy efficiency is low. This period is designated as the non-heat storage period and the system operates according to the user-set temperature, which helps to ensure indoor comfort.

[0110] In one feasible implementation, the step of adjusting the set temperature according to the outdoor temperature and its changing trend, and controlling the operation of the environmental control system according to the adjusted set temperature, includes: increasing the set indoor temperature and / or increasing the set refrigerant temperature when the outdoor temperature is trending upward and is greater than or equal to a second preset temperature, or when the outdoor temperature is trending downward and is greater than or equal to a first preset temperature; controlling the operation of the environmental control system according to the increased set indoor temperature and / or increased set refrigerant temperature; when the environmental control system operates to meet a second condition, decreasing the current set indoor temperature of the indoor terminal device and / or decreasing the current set refrigerant temperature of the refrigerant circulation system; and controlling the operation of the environmental control system according to the decreased set indoor temperature and / or decreased set refrigerant temperature, wherein the second preset temperature is greater than the first preset temperature.

[0111] The indoor temperature is increased based on a first temperature adjustment value, and / or the refrigerant temperature is increased based on a second temperature adjustment value. The first and / or second temperature adjustment values ​​can be preset fixed values, or values ​​determined based on the actual operation of the environmental control system. For example, the first and / or second temperature adjustment values ​​can be determined based on the interval between the current time and the end time of the peak power period and / or the interval between the current time and the start time of the peak power period, etc.

[0112] For example, if the indoor temperature is set to TS and the refrigerant temperature is set to TWS, then the increased indoor temperature setting is TS+△T1 and the increased refrigerant temperature setting is TWS+△T2.

[0113] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the increased set indoor temperature and / or the increased set refrigerant temperature. The control method is the same as described in the above embodiment and will not be repeated here.

[0114] The second condition indicates that the system's heat storage capacity reaches the target heat storage capacity after increasing the set indoor temperature and / or the set refrigerant temperature. In this embodiment, the second condition includes at least one of the following: the indoor temperature of the indoor space where the indoor terminal device is located reaches the increased set indoor temperature; the environmental control system maintains the increased set indoor temperature and / or the increased set refrigerant temperature for a predetermined duration. In other embodiments, the second condition may also include receiving a cooling command input by the user, or the second condition may include the environmental control system reaching the target duration when the outdoor temperature trend is upward and the outdoor temperature is greater than or equal to a second preset temperature, or when the outdoor temperature trend is downward and the outdoor temperature is greater than or equal to a first preset temperature, etc.

[0115] The reduction range of the set indoor temperature and / or set refrigerant temperature can be a preset fixed value, or a value determined according to the actual operation of the environmental control system, such as the time interval between the current time and the end time of the current time period.

[0116] The reduced indoor temperature setting is less than or equal to the original indoor temperature setting, and the reduced refrigerant temperature setting is less than or equal to the original refrigerant temperature setting.

[0117] In this embodiment, the current set indoor temperature is reduced to the previous set indoor temperature, that is, reduced from TS+△T1 to TS, and the current set refrigerant temperature is reduced to less than the previous set refrigerant temperature, that is, reduced from TWS+△T2 to TWS-△T3.

[0118] The operation of the heat pump system and / or the refrigerant circulation system is controlled according to the reduced set indoor temperature and / or the reduced set refrigerant temperature. The control method is the same as described in the above embodiment and will not be repeated here.

[0119] In this embodiment, when the outdoor temperature and its changing trend meet the above conditions, it can be considered that this period is close to the system's highest energy efficiency during the peak power period, and thus can be regarded as the peak power heat storage period (e.g., Figure 5 The system can store heat for a period of time before stopping or reducing the amount of heat stored, thereby ensuring comfort while reducing the energy consumption and cost required for continuous heat storage. The system can find the lowest temperature that meets indoor comfort through dynamic adjustment, further reducing energy consumption and cost.

[0120] In other embodiments, after increasing the set temperature, the environmental control system can be maintained at the increased set temperature until the environmental control system reaches the outdoor temperature or the outdoor temperature change trend no longer meets the above execution conditions, etc.

[0121] In other embodiments, when the second preset condition is met during peak power hours or at the current moment during peak power hours, if the outdoor temperature is greater than the second preset temperature and the outdoor temperature trend is upward, the first amplitude of the set temperature is increased and the environmental control system is maintained at the increased set temperature until the outdoor temperature trend becomes downward; if the outdoor temperature is greater than the first preset temperature and the outdoor temperature trend is downward, the set temperature is increased by a second amplitude and the environmental control system is maintained at the increased set temperature, where the second amplitude is less than the first amplitude; if the outdoor temperature is less than the first preset temperature, the environmental control system is maintained at the set temperature.

[0122] In one implementation, after the step of controlling the operation of the environmental control system based on the reduced set indoor temperature and / or the reduced set refrigerant temperature, the method further includes: If the indoor temperature of the indoor space where the indoor terminal device is located is less than or equal to the reduced set indoor temperature, return to the steps of increasing the set indoor temperature and / or increasing the set refrigerant temperature.

[0123] In this embodiment, adjusting the set temperature of the environmental control system based on the temperature fluctuations of the indoor space helps ensure that the system can meet the indoor heat exchange needs with the lowest possible heat output, thereby ensuring indoor comfort while further saving the system's energy consumption and costs.
