[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0050] An embodiment of the present invention provides an environment conditioning device, which is specifically used to condition the air in an indoor environment.

[0051] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The environment conditioning device comprises a control device 1 and at least two indoor terminal devices 31. Different indoor terminal devices are arranged in different indoor spaces, and each indoor space is provided with at least one preset sensor 5 for detecting the dew point temperature. At least two preset sensors 5 are connected to the control device 1.

[0052] The heat exchange types of the indoor terminal devices 31 in different indoor spaces may be the same or different.

[0053] In this embodiment, the indoor terminal device 31 is a radiation terminal device, such as a radiation panel, a capillary network, etc. The radiation terminal device can be installed on the wall surface of the indoor space (including the wall surface and / or the ground, etc.). In other embodiments, the indoor terminal device 31 can also be a convection heat exchange device. For example, the indoor terminal device 31 may include a fan coil, a floor heating coil, a fan disc or a heat sink, etc.

[0054] The preset sensor 5 may include a dew point temperature sensor or a temperature and humidity sensor. The dew point temperature sensor can directly detect the dew point temperature of the space in which it is located. The temperature and humidity sensor can detect the temperature and humidity of the space in which it is located, so that the control device 1 can calculate the dew point temperature according to the detected temperature and humidity. In this embodiment, the temperature and humidity sensor is a sensor that integrates temperature detection and humidity detection functions. In other embodiments, the temperature and humidity sensor may also include a temperature sensor and a humidity sensor.

[0055] The preset sensors 5 provided in different indoor spaces may be the same or different. Specifically, at least two preset sensors 5 provided in at least two indoor spaces may both be dew point sensors, or at least two preset sensors 5 provided in at least two indoor spaces may both be temperature and humidity sensors, or at least two preset sensors 5 provided in at least two indoor spaces may be partly temperature and humidity sensors and partly dew point sensors.

[0056] At least two preset sensors 5 may be provided in each indoor space, and the preset sensors 5 in the same indoor space may all be dew point sensors, or the preset sensors 5 in the same indoor space may all be temperature and humidity sensors, or some of the preset sensors 5 in the same indoor space may be dew point sensors and the other part may be temperature and humidity sensors. The preset sensors 5 in the same indoor space may be provided in different positions.

[0057] The preset sensor 5 may be built into the environment conditioning device, or may be a detection module provided independently of the environment conditioning device.

[0058] Further, in this embodiment, referring to Figure 1 and Figure 2 The environment conditioning device includes a heat pump system 2 and a refrigerant circulation system 3 connected to the heat pump system 2, and both the heat pump system 2 and the refrigerant circulation system 3 are connected to the control device 1. The refrigerant circulation system 3 transmits the energy output by the heat pump system to the indoor space through the refrigerant circulation flow to adjust the temperature of the indoor space. The heat pump system 2 is used to provide energy (such as cold or heat) for the heat exchange between the refrigerant circulation system 3 and the indoor space.

[0059] In this embodiment, the brine circulation system 3 is a water system, the heat pump system 2 is used to adjust the water supply temperature of the brine circulation system 3, and the brine circulation system 3 can adjust the indoor temperature using the indoor terminal device 31. In the embodiment of the present invention, the water supply temperature of the brine circulation system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the brine circulation system 3 can also be a system that uses a brine to transmit energy, such as an ethanol solution.

[0060] 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.

[0061] The refrigerant circulation system 3 includes a medium circulation loop and an indoor terminal device 31 and a heat exchange module arranged in the medium circulation loop. The heat exchange module is connected to the heat pump system 2 for heat exchange. The medium circulation loop has an inlet and an outlet. The inlet of the medium circulation loop is connected to the outlet of the heat exchange module, and the outlet of the medium circulation loop is connected to the inlet of the heat exchange module. The cold or heat of the refrigerant in the medium circulation loop can be released to the indoor space where it is located at the indoor terminal device 31. Based on this, the cold or heat carried by the medium in the medium circulation loop can be used to adjust the ambient temperature of more than one indoor space.

[0062] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop, which includes a compressor, a first heat exchanger, a throttling device and a second heat exchanger, and the second heat exchanger is heat-exchange connected with the heat exchange module in the refrigerant circulation system 3. The second heat exchanger and the heat exchange module can be a shell and tube heat exchanger or a plate heat exchanger.

[0063] The heat pump system 2 can have two operating modes: cooling mode and heating mode. When the heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state to absorb heat. When the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state to release heat.

[0064] During the operation of the heat pump system 2, the water in the heat exchange module can absorb the cold or heat released by the second heat exchanger to form cold water or hot water. The medium carrying cold or heat flowing out of the heat exchange module can enter the medium circulation loop and flow to the indoor terminal device 31 to release the cold or heat to the air in the indoor space to adjust the ambient temperature of the indoor space. The medium after releasing the cold or heat can re-enter the heat exchange module to exchange heat with the second heat exchanger, and the medium after heat exchange can re-enter the medium circulation loop to exchange heat, and so on, so as to realize the adjustment of the indoor space temperature by the environmental conditioning device.

[0065] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The medium in the heat exchange module absorbs the cold output by the second heat exchanger and its temperature decreases to form a medium that carries cold. The medium that carries cold enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold to the indoor space, and the ambient temperature of the indoor space decreases.

[0066] When the heat pump system 2 is in heating operation, the second heat exchanger is in a condensing state. The medium in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the indoor terminal device 31, releasing heat to the indoor space, and the ambient temperature of the indoor space rises.

[0067] Furthermore, the refrigerant circulation system 3 also includes a fluid regulating module 32, which is connected to the control device 1. The fluid regulating module 4 can be used to adjust the distribution, flow regulation and control of the supply and return liquid in the refrigerant circulation system 3. Specifically, the heat exchange module and the indoor terminal device 31 are both connected to the fluid regulating module 32. In this embodiment, the number of indoor terminal devices 31 is at least two, and at least two indoor terminal devices 31 and the heat exchange module are connected to the fluid regulating module 32. The fluid regulating module 32 includes at least two fluid valves, and the fluid valves are connected to the indoor terminal devices 31 in a one-to-one correspondence. In this embodiment, the fluid regulating module 4 is a manifold. In other embodiments, the fluid regulating module 32 may also be a circulating pump.

[0068] Furthermore, the environmental conditioning device also includes a temperature sensor 6 connected to the control device 1 , and the temperature sensor 6 is arranged on the surface of the indoor terminal device 31 or the refrigerant pipeline or the installation wall to detect temperature parameters related to the indoor terminal device 31 .

[0069] In the embodiment of the present invention, refer to Figure 2 The control device 1 of the environment conditioning device includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The various components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0070] 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 less components than shown in the figure, or combine certain components, or arrange the components differently.

[0071] 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 step operations of the control method of the environmental conditioning device in the following embodiments.

[0072] An embodiment of the present invention also provides a method for controlling an environment conditioning device.

[0073] Reference Figure 3 , an embodiment of a control method of an environmental conditioning device of the present application is proposed. In this embodiment, the control method of the environmental conditioning device includes:

[0074] Step S10, during the process that the environment conditioning device is in the refrigeration mode, when a target sensor in the target indoor space fails, obtain the detection data of the preset sensors other than the target sensor, where the target sensor is a preset sensor pre-configured for detecting the dew point temperature;

[0075] During the process that the environment conditioning device is in the refrigeration mode, the indoor terminal device releases cold to the corresponding indoor environment. In this embodiment, the environment conditioning device includes the above-mentioned heat pump system and the coolant circulation system. During the process that the environment conditioning device is in the refrigeration mode, the heat pump system operates for refrigeration and the coolant circulation system conveys the cold released by the heat pump system to the indoor terminal device in the target indoor space.

[0076] The target indoor space is one of the above-mentioned at least two indoor spaces. The target indoor space can be a space among the at least two indoor spaces that meets the set conditions (such as the indoor temperature is greater than the preset value or the temperature difference value between the indoor temperature and the target temperature is greater than the preset value, etc.), or can be a space designated by the user, or can be any space.

[0077] The existence of a failure here includes communication failure, abnormal detected data, hardware failure, etc. Whether the target sensor has a failure can be determined according to the communication situation of the target sensor and / or the detected data situation of the target sensor and / or the information input by the user.

[0078] Each indoor space can correspond to a target sensor. In this embodiment, the target sensor is a dew point sensor. In other embodiments, the target sensor can also be a temperature and humidity sensor, etc.

[0079] The target sensor can be a fixed preset sensor, or can be a preset sensor obtained by screening all the preset sensors in the indoor space according to a preset rule. For example, within the preset duration when the environment conditioning device starts the refrigeration mode, obtain the communication speed of each preset sensor in the indoor space, the detected value of each preset sensor, and the actual duration required for the exhaust temperature of the compressor in the environment conditioning device to reach the preset temperature. Here, the actual duration can represent the environmental temperature state where the environment conditioning device is located. Determine the reference value detected by the preset sensor according to the actual duration, determine the evaluation value of each preset sensor according to the communication speed of all the preset sensors and the deviation value between the detected data of each preset sensor and the reference value, and determine the preset sensor with the highest evaluation value as the target sensor.

[0080] Here, the preset sensors other than the target sensor may be located in the same indoor space as the target sensor, or in a different indoor space from the target sensor. The preset sensors other than the target sensor may be sensors of the same type as the target sensor, or sensors of a different type from the target sensor. The preset sensors other than the target sensor may be defined as other sensors, and the number of other sensors may be one or more than one.

[0081] The detection data here is the raw data directly output by the preset sensor and not analyzed. The detection data of each other sensor is obtained or one of all other sensors that meets the preset conditions (such as the closest to the target sensor or the closest to the target sensor) is obtained.

[0082] The detection data may include a dew point temperature value or temperature and humidity data related to the dew point temperature.

[0083] Step S20, determining the dew point temperature of the target indoor space according to the detection data;

[0084] When there is one preset sensor other than the target sensor and it is a dew point sensor, the temperature value detected by the dew point sensor can be determined as the dew point temperature here.

[0085] When there is only one preset sensor other than the target sensor and it is a temperature and humidity sensor, the dew point temperature here can be determined according to the temperature and humidity data detected by the temperature and humidity sensor.

[0086] When there are more than one preset sensors other than the target sensor and all of them are dew point sensors, the dew point temperature here can be determined according to more than one temperature values ​​detected by the more than one dew point sensors.

[0087] When there are more than one preset sensors other than the target sensor and all of them are temperature and humidity sensors, the dew point temperature here can be determined according to more than one temperature and humidity data detected by the more than one temperature and humidity sensors.

[0088] When there are more than one preset sensors other than the target sensor and some are dew point sensors and others are temperature and humidity sensors, the dew point temperature here can be determined by determining at least one temperature and humidity data detected by the corresponding temperature and humidity sensors and at least one temperature value detected by the corresponding dew point sensor.

[0089] In this embodiment, the correspondence between the detection data and the dew point temperature can be preset, and the correspondence can include a calculation formula, a mapping table, a deep learning model, etc. Based on the correspondence, the dew point temperature corresponding to the current detection data can be determined.

[0090] When the number of target indoor spaces is more than one, the corresponding dew point temperature may be determined according to the detection data corresponding to each target indoor space.

[0091] Step S30, controlling the anti-condensation operation of the environmental conditioning device according to the dew point temperature.

[0092] Specifically, the anti-condensation operation of the environmental conditioning equipment may be controlled according to the dew point temperature and the temperature parameters related to the indoor terminal equipment in the target indoor space.

[0093] The temperature parameters here include at least one of the following parameters: surface temperature, liquid inlet temperature, liquid outlet temperature, surface temperature change value, liquid inlet and outlet temperature difference, wall temperature, coolant temperature, etc.

[0094] The anti-condensation operation of the environmental conditioning equipment is controlled according to the size relationship or quantitative relationship between the dew point temperature and the temperature parameter.

[0095] Anti-condensation operation specifically refers to one or more components in the environmental conditioning equipment operating at operating parameters that reduce the risk of condensation in the indoor space of the environmental conditioning. The components in the environmental conditioning equipment that operate in anti-condensation mode include but are not limited to at least one of the following: a compressor, an indoor fan, a fluid conditioning module, a throttling device, and the like.

[0096] When the number of target indoor spaces is more than one, the operation of the environment regulating device can be controlled according to the temperature parameters of the indoor terminal device in each target indoor space and the corresponding dew point temperature.

[0097] A control method for an environmental conditioning device is proposed in an embodiment of the present invention. In the method, the environmental conditioning device includes at least two indoor terminal devices arranged in different indoor spaces. Preset sensors for detecting dew point temperatures are arranged in different indoor spaces. During the cooling operation of the environmental conditioning device, when a target sensor pre-set in the target indoor space for detecting dew point temperature fails, the cooling of the indoor terminal device is no longer stopped directly. Instead, the dew point temperature of the target indoor space is determined using detection data from other preset sensors. Based on the determined dew point temperature, the anti-condensation operation of the environmental conditioning device is controlled to ensure that the environmental conditioning device can maintain cooling the room when the target sensor fails, thereby reducing the risk of condensation in the indoor space while improving the cooling comfort of indoor users.

[0098] Furthermore, in the present embodiment, the step of obtaining detection data of the preset sensor other than the target sensor includes: obtaining first data detected by the preset sensor other than the target sensor in the target indoor space, and / or obtaining second data detected by the preset sensor in indoor spaces other than the target indoor space in at least two of the indoor spaces.

[0099] Define the preset sensors other than the target sensor in the target indoor space as the first preset sensors. The first sensors can be dew point sensors or temperature and humidity sensors. The number of the first preset sensors can be one or more than one, and the first data detected by all the first preset sensors in the target indoor space or the first preset sensors meeting the preset conditions can be obtained. Specifically, the first data detected by the temperature and humidity sensors other than the target sensor in the target indoor space and / or the first data detected by the dew point sensors can be obtained.

[0100] Define the preset sensors other than the target sensor in the target indoor space as the second preset sensors. The second sensors can be dew point sensors or temperature and humidity sensors. The number of the second preset sensors can be one or more than one, and the second data detected by all the second preset sensors outside the target indoor space or the second preset sensors meeting the preset conditions can be obtained. Specifically, the second data detected by the temperature and humidity sensors in the indoor space outside the target indoor space and / or the second data detected by the dew point sensors can be obtained.

[0101] In this embodiment, when the target sensor fails, the dew point temperature can be detected by other preset sensors in the same space and / or preset sensors in other spaces, so as to effectively characterize the dew point temperature of the target indoor space, ensure that the cold input to the target indoor space does not stop, and ensure the anti-condensation of the environmental control equipment based on the obtained dew point temperature while ensuring the refrigeration stability of the target indoor space.

[0102] Further, based on the above embodiment, another embodiment of the control method of the environmental control equipment of the present application is proposed. In this embodiment, the preset sensors include dew point sensors or temperature and humidity sensors, and at least two of the preset sensors are arranged in each indoor space. Referring to Figure 4 , the step of obtaining the first data detected by the preset sensors other than the target sensor in the target indoor space includes:

[0103] Step S11, when there is an unfailed dew point sensor other than the target sensor in the target indoor space, obtain the temperature value detected by the unfailed dew point sensor in the target indoor space to obtain the first data;

[0104] Here, there can be one or more than one unfailed dew point sensor in the target indoor space. When there are more than one unfailed dew point sensors, the temperature values detected by each unfailed dew point sensor can be obtained to obtain more than one temperature value.

[0105] Step S12: when all dew point sensors other than the target sensor in the target indoor space fail or there is no dew point sensor other than the target sensor in the target indoor space, obtain temperature and humidity data detected by a normal temperature and humidity sensor in the target indoor space to obtain the first data.

[0106] Here, there may be one or more than one temperature and humidity sensors that are not faulty in the target indoor space. When there are more than one temperature and humidity sensors that are not faulty, the temperature and humidity data detected by each temperature and humidity sensor that is not faulty may be obtained to obtain more than one temperature and humidity data.

[0107] In this embodiment, when the target sensor fails, the dew point temperature determined by the temperature value detected by the normal dew point sensor in the same space is preferentially used for anti-condensation control; when there is no normal dew point sensor, the dew point temperature determined by the temperature and humidity data detected by the temperature and humidity sensor is used for anti-condensation control. Since the dew point sensor can directly detect the dew point temperature without data analysis, while the temperature and humidity sensor requires data analysis to detect the dew point temperature, this is beneficial to improving the timeliness of the anti-condensation operation of the environmental conditioning equipment when the target sensor fails, thereby improving the indoor cooling comfort while reducing the condensation risk of the indoor space.

[0108] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. Figure 5 The step of acquiring first data detected by the preset sensor other than the target sensor in the target indoor space, and / or acquiring second data detected by the preset sensor in the indoor space other than the target indoor space comprises:

[0109] Step S101, when at least one preset sensor other than the target sensor in the target indoor space is not faulty, executing the step of acquiring first data detected by the preset sensor other than the target sensor in the target indoor space;

[0110] Step S102, when all preset sensors other than the target sensor in the target indoor space fail, executing the step of acquiring second data detected by the preset sensors in the indoor space other than the target indoor space.

[0111] For example, all preset sensors in the target indoor space include a first dew point sensor and a first temperature and humidity sensor, and the first indoor space outside the target indoor space includes a second dew point sensor and a second temperature and humidity sensor, wherein the first dew point sensor is the target sensor. When both the first dew point sensor and the first temperature and humidity sensor fail, the second data detected by the second dew point sensor and / or the second temperature and humidity sensor is obtained to determine the dew point temperature of the target indoor space; when the first dew point sensor fails and the first temperature and humidity sensor is not failed, the first data detected by the first temperature and humidity sensor is obtained to determine the dew point temperature of the target indoor space.

[0112] In this embodiment, data detected by a non-faulty preset sensor in the target indoor space is preferentially used to determine the dew point temperature of the target indoor space. When all preset sensors in the target indoor space fail, detection data from other indoor spaces are used to determine the dew point temperature. This is beneficial to improving the accuracy of the determined dew point temperature in representing the actual dew point conditions of the target indoor space, thereby ensuring indoor cooling comfort while further reducing the condensation risk of environmental conditioning equipment.

[0113] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. Figure 6 , the preset sensor includes a dew point sensor or a temperature and humidity sensor, and the step of determining the dew point temperature of the target indoor space according to the detection data includes:

[0114] Step S21 , determining the dew point temperature according to temperature and humidity data detected by a temperature and humidity sensor other than the target sensor that is not faulty and / or a temperature value detected by a dew point sensor other than the target sensor that is not faulty.

[0115] When the detection data includes temperature and humidity data, a reference value of the corresponding dew point temperature can be determined according to the temperature and humidity data, and the dew point temperature can be determined according to the reference value. Wherein, when the detection data includes one temperature and humidity data, the reference value is determined to be the dew point temperature. When the detection data includes more than one temperature and humidity data detected by more than one temperature and humidity sensor, a reference value of the dew point temperature corresponding to each temperature and humidity data is determined; and the dew point temperature is determined according to more than one reference value. In this embodiment, the maximum value among all reference values ​​is determined to be the dew point temperature.

[0116] When the detection data includes the temperature value detected by the dew point sensor but does not include the temperature and humidity data detected by the temperature and humidity sensor, the detection data includes a temperature value detected by a dew point sensor, and the temperature value is determined to be the dew point temperature; the detection data includes more than one temperature value detected by more than one dew point sensor, and the dew point temperature is determined according to the more than one temperature value. In this embodiment, the maximum value of more than one temperature value is determined to be the dew point temperature.

[0117] When the detection data includes the temperature value detected by the dew point sensor and the temperature and humidity data detected by the temperature and humidity sensor, a reference value of the dew point temperature corresponding to the temperature and humidity data can be determined, and the dew point temperature can be determined based on the reference value and the temperature difference value detected by the dew point sensor.

[0118] In this embodiment, the above-mentioned method can be used to achieve that when a target sensor fails, the data detected by other non-faulty dew point sensors and / or temperature and humidity sensors can accurately represent the dew point temperature of the target indoor space, thereby reducing the risk of condensation in the indoor space while further improving the cooling stability of the target indoor space, thereby effectively improving the cooling comfort.

[0119] In other embodiments, the average of all reference values ​​may be determined as the dew point temperature. Alternatively, the average of all temperature values ​​may be determined as the dew point temperature.

[0120] Among them, when the detection data includes second data (the second data may include temperature value and / or temperature and humidity data, etc.), the relationship value between the total cooling time of the indoor space where the preset sensor corresponding to the second data is located and the total cooling time of the target indoor space is obtained, and the reference temperature of the dew point temperature is determined according to the second data. After correcting the reference temperature according to the relationship value, the dew point temperature of the target indoor space is obtained.

[0121] Further, based on any of the above embodiments, in this embodiment, the environmental conditioning device includes a heat pump system and a refrigerant circulation system connected to the heat pump system for heat exchange, the refrigerant circulation system includes the at least two indoor terminal devices, and the control method of the environmental conditioning device also includes: when the environmental conditioning device is in a cooling mode, when all of the preset sensors are faulty, controlling the heat pump system to shut down and / or controlling the refrigerant circulation system to stop delivering cold air to the at least two indoor terminal devices; when the environmental conditioning device is in a cooling mode, when there is no fault in the preset sensors other than the target sensor and the target sensor is faulty, executing the step of obtaining the detection data of the preset sensors other than the target sensor.

[0122] The process of the refrigerant circulation system stopping delivering cold air to at least two indoor terminal devices specifically includes: controlling at least two fluid valves corresponding to the at least two indoor terminal devices to be closed, and / or controlling the circulation pump in the refrigerant circulation system to be closed.

[0123] In this embodiment, through the above method, when the dew point temperature of the target indoor space cannot be determined through the data detected by the preset sensor, the heat pump system is shut down and / or the refrigerant circulation system is stopped from delivering cold air in time, thereby ensuring that the environmental conditioning equipment will not be damaged due to condensation, so as to further effectively protect the environmental conditioning equipment.

[0124] Further, based on any of the above embodiments, in this embodiment, the environmental conditioning equipment includes a heat pump system and a refrigerant circulation system connected to the heat pump system for heat exchange, the refrigerant circulation system includes the at least two indoor terminal devices, the temperature parameter includes the inlet liquid temperature of the indoor terminal device, and the step of controlling the anti-condensation operation of the environmental conditioning equipment according to the dew point temperature includes: determining the temperature difference between the inlet liquid temperature and the dew point temperature; controlling the anti-condensation operation of the heat pump system and / or the refrigerant circulation system according to the temperature difference.

[0125] Specifically, the operation of the compressor and / or throttling device in the heat pump system can be controlled according to the temperature difference, and / or the operation of the fluid regulating module in the refrigerant circulation system and / or the indoor fan in the indoor terminal equipment can be controlled according to the temperature difference.

[0126] In this embodiment, the temperature difference value can accurately characterize the condensation risk of the target indoor space, and thus the heat pump system and / or the refrigerant circulation system are controlled to prevent condensation based on the temperature difference value, thereby further effectively reducing the condensation risk of the indoor space.

[0127] Furthermore, the step of controlling the anti-condensation operation of the heat pump system and / or the refrigerant circulation system according to the temperature difference includes: when the temperature difference is less than a first preset value and greater than or equal to a second preset value, increasing the target refrigerant temperature of the refrigerant circulation system, and controlling the operation of the heat pump system according to the increased target refrigerant temperature; when the temperature difference is less than a second preset value, controlling the refrigerant circulation system to stop delivering cold air to the indoor terminal equipment in the target indoor space; wherein the second preset value is less than the first preset value.

[0128] The temperature difference value is negatively correlated with the condensation risk represented. The smaller the temperature difference value, the greater the condensation risk, and the larger the temperature difference value, the smaller the condensation risk.

[0129] The temperature adjustment value for increasing the target refrigerant temperature here can be a pre-set fixed value or a value determined according to the actual operation of the system. For example, the temperature adjustment value here can be determined based on the type of preset sensor currently used to determine the dew point temperature (dew point sensor or temperature and humidity sensor), the space where the preset sensor currently used to determine the dew point temperature is located (in the target indoor space or in the indoor space outside the target indoor space), and the environmental conditions of other spaces where the preset sensor currently used to determine the dew point temperature is located (for example, whether the indoor terminal device turns on cooling, etc.).

[0130] The first preset value is a critical value for distinguishing whether there is a condensation risk, and the second preset value is a critical value for distinguishing whether the condensation risk is high or low.

[0131] When the temperature difference is less than the first preset value and greater than or equal to the second preset value, the indoor space has a condensation risk. At this time, the target refrigerant temperature is increased to reduce the condensation risk, which is conducive to ensuring the continuity of the input cooling capacity of the indoor space, thereby reducing the condensation risk and further improving the cooling comfort. When the temperature difference is less than the second preset value, the condensation risk of the indoor space is very high. At this time, even if the cold capacity is stopped from being delivered to the indoor terminal equipment of the target indoor space, the indoor terminal equipment is further protected from damage due to condensation.

[0132] Further, based on any of the above embodiments, the control method of the environmental conditioning device also includes: when the data detected by the preset sensor is not received or the received data detected by the preset sensor exceeds a preset value range, determining that the preset sensor is faulty.

[0133] The preset numerical range may be a pre-set fixed range, or a range determined according to the actual operating conditions of the environmental adjustment device. For example, the preset numerical range here may be determined according to the cooling time of the indoor terminal device.

[0134] It should be noted that any of the preset sensors mentioned above (including the target sensor and preset sensors other than the target sensor) can perform fault identification in the manner mentioned here.

[0135] In this embodiment, it can be achieved that when a preset sensor fails due to abnormal communication or data detection, it can be quickly and accurately identified.

[0136] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program of an environmental conditioning device is stored. When the control program of the environmental conditioning device is executed by a processor, the relevant steps of any embodiment of the control method of the environmental conditioning device as described above are implemented.
