[0078] The indoor terminal devices 31 can be one or more, and the more than one indoor terminal devices 31 can be distributed in different indoor spaces. The heat exchange types of the indoor terminal devices 31 in different indoor spaces can be the same or different. Based on this, the cooling or heating carried by the medium in the medium circulation loop can be used to regulate the environmental temperature of more than one indoor space.

[0096] It should be understood that parts of the present application can be realized by hardware, software, firmware or a combination thereof. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0097] The above is merely specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.

[0098] Based on this, the embodiments of the present application provide a control method of an environment adjusting device, referring to Figure 3 In the first embodiment of the present application, the control method of the environment adjusting device comprises steps S10-S40:

[0099] Step S10, obtaining a state parameter, the state parameter indicating the heat preservation ability of the envelope structure in the indoor space adjusted by the environment adjusting device;

[0100] The state parameter can include the operating parameter related to the heat preservation ability of the environment adjusting device itself and / or the state parameter related to the heat preservation ability of the envelope structure and / or the environmental state parameter of the indoor space, etc.

[0101] In the embodiment, the state parameter includes at least one of the following: a temperature state parameter (e.g., at least one of a temperature variation amplitude, a temperature variation rate, an average temperature, a maximum temperature, a minimum temperature, etc.) of the indoor space, a temperature state parameter (e.g., at least one of a temperature variation amplitude, a temperature variation rate, an average temperature, a maximum temperature, a minimum temperature, etc.) of the secondary refrigerant of the secondary refrigerant circulation system, a state parameter (e.g., an open / close state or an opening degree, etc.) of a passage opening on the envelope structure of the indoor space that is in communication with the outdoor, a temperature difference state parameter between the indoor and the outdoor, etc.

[0102] In step S20, a target secondary refrigerant temperature of the secondary refrigerant circulation system is determined according to the state parameter.

[0103] In the embodiment, the target secondary refrigerant temperature is a target value of the temperature of the secondary refrigerant flowing out of the heat exchange module after heat exchange. In other embodiments, the target secondary refrigerant temperature can also be a target value of the return liquid temperature of the heat exchange module, a target value of the inlet liquid temperature of the indoor terminal device, a target value of the outlet liquid temperature of the indoor terminal device, etc.

[0104] Different state parameters correspond to different target secondary refrigerant temperatures.

[0105] In one implementation, a correspondence between different state parameters and target secondary refrigerant temperatures is established in advance, which can include a calculation formula, a mapping relationship, etc. The target secondary refrigerant temperature corresponding to the current state parameter can be determined based on the correspondence. For example, the current state parameter is substituted into a preset formula to calculate the target secondary refrigerant temperature. For another example, different parameter intervals correspond to different target secondary refrigerant temperatures. The parameter interval in which the state parameter is located is determined, and the secondary refrigerant temperature corresponding to the parameter interval is taken as the target secondary refrigerant temperature.

[0106] In another implementation, a correspondence between different state parameters and temperature adjustment parameters is established in advance, which can include a calculation formula, a mapping relationship, etc. The temperature adjustment parameter corresponding to the current state parameter can be determined based on the correspondence, and the target value of the initial secondary refrigerant temperature or the target value of the current secondary refrigerant temperature is adjusted according to the temperature adjustment parameter to obtain the target secondary refrigerant temperature.

[0107] In step S30, the environmental regulation device is controlled to operate according to the target secondary refrigerant temperature.

[0108] The control objects can include, but are not limited to, compressor frequency, fan speed, operating parameters of a fluid regulating module, opening degree of an electronic expansion valve, etc. The control objects in the heat pump system and / or the coolant circulation system are controlled to reach the target coolant temperature of the coolant flowing out of the heat exchange module or flowing into the terminal device. For example, when the heat pump system operates in a heating mode, the compressor frequency is increased when the current coolant temperature is less than the target coolant temperature, and the compressor frequency is decreased when the current coolant temperature is greater than the target coolant temperature, etc.

[0109] The embodiment provides a control method of an environmental regulation device. The method determines a target coolant temperature of a coolant circulation system according to a state parameter representing an insulation capacity of a maintenance structure of an indoor space, and controls the environmental regulation device to operate according to the target coolant temperature. In the process, the target coolant temperature of the coolant circulation system is no longer fixedly set according to a user setting temperature, but can be configured according to the insulation capacity of the indoor space, so as to ensure that the operation of the environmental regulation device can be matched with an actual working condition, effectively improve the matching degree of the room temperature and the temperature range required by the user, and improve the comfort of the user in the indoor space.

[0110] In an available implementation, the step S10 can include: acquiring an indoor temperature state parameter of the indoor space regulated by the environmental regulation device in a target time period and a coolant temperature state parameter of the coolant circulation system in the target time period; and the state parameter includes the indoor temperature state parameter and the coolant temperature state parameter.

[0111] The target time period can be a fixed time length set in advance, or a time length determined according to an actual operation state of the environmental regulation device. An initial time point of the target time period can be a time point at which the environmental regulation device enters a preset state mentioned later, or a time point at which the target coolant temperature is determined last time, etc.

[0112] The indoor temperature state parameter represents a parameter of an overall temperature state of the indoor environment in the target time period. The indoor temperature state parameter can include at least one of the following: average indoor temperature, maximum indoor temperature, minimum indoor temperature, indoor temperature variation amplitude, indoor temperature variation rate, etc.

[0113] The coolant temperature state parameter represents a parameter of an overall temperature state of the coolant in the coolant circulation system in the target time period. The coolant temperature state parameter can include at least one of the following: average coolant temperature, maximum coolant temperature, minimum coolant temperature, coolant temperature variation amplitude, coolant temperature variation rate, etc.

[0114] In an implementation, the target chilled refrigerant temperature can be determined according to the first parameter interval in which the indoor temperature state parameter is located and / or the second parameter interval in which the chilled refrigerant temperature state parameter is located. In another implementation, the target chilled refrigerant temperature can be determined according to the relationship value between the indoor temperature state parameter and the chilled refrigerant temperature state parameter.

[0115] In the embodiment, the indoor temperature state parameter and the chilled refrigerant temperature state parameter in a period of time can accurately reflect the heat preservation condition of the indoor space, and thus determining the target chilled refrigerant temperature through the indoor temperature state parameter and the chilled refrigerant temperature state parameter is conducive to ensuring that the operation of the environmental regulation device matches the actual heat preservation capability of the indoor space, so as to further improve the matching degree of the room temperature and the temperature interval required by the user and improve the comfort of the user in the indoor space.

[0116] Based on any of the above embodiments, in the second embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be described in detail hereinafter. On this basis, in the embodiment, when the environmental regulation device is in the heating mode, the indoor temperature state parameter includes an indoor cooling rate, and the chilled refrigerant temperature state parameter includes a chilled refrigerant characteristic temperature. The indoor cooling rate is determined according to the ratio of the temperature difference between the initial indoor temperature and the current indoor temperature to the target time period. The initial indoor temperature is specifically the temperature detected at the starting moment of the target time period. In the embodiment, the chilled refrigerant characteristic temperature is the average value of at least two chilled refrigerant temperatures detected in the target time period. In other embodiments, the chilled refrigerant characteristic temperature can also be the maximum value or the minimum value of at least two chilled refrigerant temperatures detected in the target time period, and the like.

[0117] Referring to Figure 4 , the step S20 includes steps S21 to S23:

[0118] In step S21, when the indoor cooling rate is greater than a preset rate and the chilled refrigerant characteristic temperature is greater than a preset temperature, a first temperature is determined as the target chilled refrigerant temperature.

[0119] In step S22, when the indoor cooling rate is less than or equal to the preset rate and the chilled refrigerant characteristic temperature is greater than the preset temperature, or when the indoor cooling rate is greater than the preset rate and the chilled refrigerant characteristic temperature is less than or equal to the preset temperature, a second temperature is determined as the target chilled refrigerant temperature.

[0120] In step S23, when the indoor cooling rate is less than or equal to the preset rate and the chilled refrigerant characteristic temperature is less than or equal to the preset temperature, a third temperature is determined as the target chilled refrigerant temperature.

[0121] Wherein, the first temperature is greater than the second temperature, and the second temperature is greater than the third temperature.

[0122] The sequence of the steps S21 to S23 is not limited.

[0123] The preset rate and the preset temperature can be fixed parameters set in advance, or parameters determined according to the actual running state of the environment adjusting device. For example, the preset rate and the preset temperature can be determined according to the temperature difference between indoor and outdoor, the temperature difference between indoor temperature and set temperature, etc.

[0124] The first temperature, the second temperature and the third temperature can be preset temperatures, or temperatures determined according to the actual running state of the environment adjusting device. For example, the first temperature, the second temperature or the third temperature can be determined according to the deviation of indoor cooling rate from the preset rate, and / or the deviation of the characteristic temperature of the cooling agent from the preset temperature, and / or the distance between the indoor terminal device and the passage of the indoor space, etc.

[0125] For example, when the indoor cooling rate is greater than 1.5℃ / min and the characteristic temperature of the cooling agent is greater than 35℃, the target temperature of the cooling agent is 55℃; when the indoor cooling rate is greater than 1.5℃ / min and the characteristic temperature of the cooling agent is less than or equal to 35℃, or the indoor cooling rate is less than or equal to 1.5℃ / min and the characteristic temperature of the cooling agent is greater than 35℃, the target temperature of the cooling agent is 40℃; when the indoor cooling rate is less than or equal to 1.5℃ / min and the characteristic temperature of the cooling agent is less than or equal to 35℃, the target temperature of the cooling agent is 30℃.

[0126] In the embodiment, when the heating capacity of the environment adjusting device is large and the cooling rate is fast during the heating process, it indicates that the heat preservation capacity of the envelope structure is poor and the heat leakage of the indoor space is serious, at this time, the target temperature of the cooling agent is set to a higher first temperature, so as to ensure that the environment adjusting device has sufficient heating capacity, avoid the indoor temperature being too low, and improve the indoor comfort; when the heating capacity of the environment adjusting device is small and the cooling rate is small during the heating process, it indicates that the heat preservation capacity of the envelope structure is good and the heat leakage of the indoor space is small, at this time, the target temperature of the cooling agent is set to a lower third temperature, so as to maintain the temperature of the indoor space in the temperature range required by the user, and the environment is not overheated while saving the energy consumption of the environment adjusting device; when the heating capacity of the environment adjusting device is large but the cooling rate is low, or the heating capacity of the environment adjusting device is small but the cooling rate is high, it indicates that the heat preservation capacity of the envelope structure is general, at this time, the target temperature of the cooling agent is set to a moderate second temperature, which is conducive to achieving the balance between energy saving and user demand satisfaction.

[0127] Further, in the embodiment, the refrigerant circulation system comprises at least two indoor terminal devices, and the step of obtaining the indoor cooling rate and the refrigerant characteristic temperature in the target time period comprises: obtaining at least two sub-indoor cooling rates corresponding to the at least two indoor terminal devices in the target time period; and determining the indoor cooling rate according to the at least two sub-indoor cooling rates.

[0128] A temperature difference value of each indoor terminal device is determined, and a sub-indoor cooling rate of each space is determined according to a ratio of each temperature difference value to a length of the target time period.

[0129] In the embodiment, a maximum value of the at least two sub-indoor cooling rates is determined as the indoor cooling rate.

[0130] In the embodiment, by the above manner, the matching degree of the temperature of each indoor space of the environment adjusting device and the user demand temperature interval is improved. The maximum cooling rate in all indoor spaces is used to determine the target refrigerant temperature, which helps to ensure that the environment adjusting device can provide sufficient heat to ensure that the temperature of each indoor space is not too low, thereby effectively ensuring the comfort of each indoor space.

[0131] In other embodiments, a mean value of the at least two sub-indoor cooling rates can also be determined as the indoor cooling rate.

[0132] Based on any of the above embodiments, in a third embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be described in detail. On this basis, in the embodiment, referring to Figure 5 , the step of controlling the operation of the environment adjusting device according to the target refrigerant temperature further comprises steps S40 to S60:

[0133] Step S40, detecting an environment temperature of an environment where the environment adjusting device is located;

[0134] The environment temperature comprises an indoor environment temperature and / or an outdoor environment temperature.

[0135] Step S50, adjusting the target refrigerant temperature according to the environment temperature;

[0136] Different environment temperatures correspond to different temperature adjustment parameters, the temperature adjustment parameter can be determined according to the environment temperature, and the target refrigerant temperature is adjusted according to the temperature adjustment parameter.

[0137] In an implementation, the ambient temperature comprises an indoor ambient temperature, when the indoor ambient temperature is less than a lower limit temperature of a preset temperature range, the target chilled carrier temperature is increased; when the indoor ambient temperature is within the preset temperature range, the target chilled carrier temperature is maintained; when the indoor ambient temperature is greater than an upper limit temperature of the preset temperature range, the target chilled carrier temperature is decreased. The preset temperature range can be determined according to a set temperature set by a user, and the temperature within the preset temperature range when the environmental regulation device is in a preset state is less than or equal to the set temperature, so that energy saving and comfort can be considered. Based on this, the indoor ambient temperature can be maintained within the preset temperature range.

[0138] In another implementation, the ambient temperature comprises an outdoor ambient temperature, a temperature difference value between the outdoor ambient temperature and an initial temperature of an outdoor environment is determined, when the temperature difference value is less than a lower limit value of a preset temperature difference range, the target chilled carrier temperature is increased; when the temperature difference value is greater than an upper limit value of the preset temperature difference range, the target chilled carrier temperature is decreased; when the temperature difference value is within the preset temperature difference range, the target chilled carrier temperature is maintained. Based on this, the target chilled carrier temperature can be adapted to the change of the outdoor ambient temperature, so that the heat supply of the environmental regulation device can not be too much or too little, and effective consideration of energy saving and comfort can be achieved.

[0139] In the embodiment, the temperature adjustment parameter when the target chilled carrier temperature is increased or decreased can be a fixed parameter set in advance, or can be a parameter determined according to the actual operation of the environmental regulation device, for example, the temperature adjustment parameter can be determined according to the temperature difference value between the indoor ambient temperature and the upper limit temperature or the lower limit temperature, the temperature adjustment parameter can be determined according to the temperature difference value between the outdoor ambient temperature and the initial temperature of the outdoor environment, and the like.

[0140] In step S60, the environmental regulation device is controlled to operate according to the adjusted target chilled carrier temperature.

[0141] In the embodiment, when the environmental regulation device is in the preset state, steps S40 to S60 can be performed at intervals of a set time length until there is a user in the indoor space after step S30.

[0142] In the embodiment, the operation of the environmental regulation device is ensured to be accurately matched with the heat preservation capacity of the envelope structure and the change of the environmental state by the above-mentioned manner, so that the matching degree of the room temperature and the temperature range of the user demand is further improved, and the comfort of the user in the indoor space is improved.

[0143] Based on any of the above-mentioned embodiments, in a fourth embodiment of the present application, the same or similar contents as the above-mentioned embodiments can be referred to the above-mentioned description, and will not be described in detail. On this basis, in the embodiment, referring to Figure 6After step S30, the method further comprises: returning to the step of acquiring the state parameter after an interval of a preset time period.

[0144] The preset time period can be a preset fixed time period, or a time period determined according to the actual operation of the environment adjusting device, for example, the preset time period can be determined according to the outdoor environment temperature and / or the interval between the current time and the time when the user returns to the indoor space.

[0145] In this embodiment, the heat supply of the environment adjusting device can be dynamically adjusted according to the actual heat leakage state of the envelope structure, so as to ensure that the temperature of the indoor space can be maintained within the temperature range required by the user, thereby further improving the comfort of the user in the indoor space.

[0146] Based on any of the above embodiments, in a fifth embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above description, and will not be described hereinafter. On this basis, in this embodiment, when the environment adjusting device is in a preset state, the step of acquiring the state parameter is performed; wherein, the preset state includes running a heat exchange mode and the indoor space does not exist a user; or, the preset state includes running a heat exchange mode and the environment adjusting device is turned on an away function.

[0147] The heat exchange mode includes a cooling mode or a heating mode. In this embodiment, the heat exchange mode is a heating mode, and the indoor terminal device is in a heating state in the heat exchange mode.

[0148] The environment adjusting device can be considered as not existing a user when at least one of the following conditions is met: receiving a user inputted leaving instruction, the current time of the air conditioner reaches the user set leaving time, there is no feature information corresponding to a human body in the environment detection parameter of the indoor space, etc.

[0149] In this embodiment, by the above method, the heat supply of the environment adjusting device when the user is not in the indoor space can be maintained not too much or too little, so as to save energy and ensure that the temperature can be quickly raised to the user's comfortable state when the user returns to the indoor space.

[0150] Further, in this embodiment, before the step of acquiring the state parameter in the target time period, the method further comprises: when the environment adjusting device enters the preset state, controlling the environment adjusting device to run at a low load.

[0151] The heat supply when the environment adjusting device runs at a low load is less than the heat supply when the environment adjusting device is in a heat exchange mode and the indoor space exists a user.

[0152] The environment adjusting device can run at a low load according to a preset fixed load parameter, or run at a low load according to a load parameter determined according to the actual operation state of the environment adjusting device.

[0153] In the embodiment, the above-mentioned manner is favorable for saving energy consumption.

[0154] Further, in the embodiment, before the step of controlling the environmental regulation device to operate at low load, the method further comprises: detecting an initial chilled agent temperature of the indoor terminal device and an initial environmental temperature of the indoor space corresponding to the initial chilled agent temperature when the environmental regulation device enters the preset state; determining an initial target value of the chilled agent temperature in the chilled agent circulation system according to the initial chilled agent temperature and a minimum chilled agent temperature, and determining a target environmental temperature of the indoor space according to the initial environmental temperature and a minimum environmental temperature; and controlling the environmental regulation device to operate at low load according to the initial target value and the target environmental temperature.

[0155] The minimum chilled agent temperature is specifically a minimum value of a target chilled agent temperature set by a user. The minimum environmental temperature is a minimum value of a target environmental temperature set by the user.

[0156] In the embodiment, the initial chilled agent temperature is reduced according to the first adjustment value to obtain a reference chilled agent temperature, and the minimum value between the reference chilled agent temperature and the set minimum chilled agent temperature is determined as the initial target value. In the embodiment, the first adjustment value is a fixed value set in advance. In other embodiments, the first adjustment value can also be a value determined according to the actual operation of the environmental regulation device.

[0157] In the embodiment, the initial environmental temperature is reduced according to the second adjustment value to obtain a reference environmental temperature, and the maximum value between the reference environmental temperature and the set minimum environmental temperature is determined as the target environmental temperature. In the embodiment, the second adjustment value is a fixed value set in advance. In other embodiments, the second adjustment value can also be a value determined according to the actual operation of the environmental regulation device.

[0158] In the embodiment, the above-mentioned manner is favorable for guaranteeing the energy-saving effect of the device in the preset state and for quickly increasing the environmental temperature to a user's comfortable state when the user returns to the indoor space. The determination of the reference chilled agent temperature and the initial target value being the minimum value between the reference chilled agent temperature and the set minimum chilled agent temperature are favorable for guaranteeing the energy-saving effect of the device. The determination of the reference environmental temperature and the target environmental temperature being the maximum value between the reference environmental temperature and the set minimum environmental temperature are favorable for energy saving and for avoiding over-regulation and improving the efficiency of increasing the indoor temperature to a user's comfortable temperature when the user returns to the indoor space.

[0159] In other embodiments, the average of the initial refrigerant temperature and the minimum refrigerant temperature can be determined as the initial target value, or the minimum refrigerant temperature can be determined as the initial target value; the average of the initial ambient temperature and the minimum ambient temperature can be determined as the target ambient temperature, or the minimum ambient temperature can be determined as the target ambient temperature.
