[0044] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0045] 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.

[0046] An embodiment of the present invention provides an air conditioning system.

[0047] In the embodiment of the present invention, referring to Figure 1 and Figure 2 , the air conditioning system includes a control device 1, an environmental conditioning device 10 and a dehumidifier 20. The environmental conditioning device 10 and the dehumidifier 20 are both connected to the control device 1. The environmental conditioning device 10 includes a heat pump system 2 and an indoor terminal device 31, and the indoor terminal device 31 is used to adjust the indoor space by using the energy (cooling capacity or heating capacity) of the heat pump system 2.

[0048] The environmental conditioning device 10 is used to adjust the indoor environmental temperature. The dehumidifier 20 is used to reduce the indoor environmental humidity.

[0049] In this embodiment, the dehumidifier 20 is used to adjust the humidity of more than one indoor space. In other embodiments, the dehumidifier 20 can be used to adjust the humidity of one indoor space.

[0050] In the embodiment of the present invention, referring to Figure 1 , the environmental conditioning device includes a heat pump system 2 and a refrigerant circulation system 3 connected to the heat pump system 2. The heat pump system 2 and the refrigerant circulation system 3 are both connected to the control device 1. The refrigerant circulation system 3 transports the energy output by the heat pump system to the indoor space through the circulation of the refrigerant to adjust the temperature of the indoor space. The heat pump system 2 is used to provide energy (such as cooling capacity or heating capacity) for the heat exchange between the refrigerant circulation system 3 and the indoor space.

[0051] In this embodiment, the secondary refrigerant circulation system 3 is a water system. The heat pump system 2 is used to adjust the water supply temperature of the secondary refrigerant circulation system 3. The secondary refrigerant circulation system 3 can utilize the indoor terminal equipment 31 to adjust the indoor temperature. In the embodiment of the present invention, the water supply temperature of the secondary refrigerant circulation system 3 can be understood as the water outlet temperature of the heat pump system 2. In other embodiments, the secondary refrigerant circulation system 3 can also be a system that uses a secondary refrigerant to transfer energy, such as an ethanol solution, etc.

[0052] In this embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 can also be a water source heat pump system, a ground source heat pump system, a dual-source heat pump system, etc.

[0053] The secondary refrigerant circulation system 3 includes a medium circulation loop and the indoor terminal equipment 31 and a heat exchange module provided in the medium circulation loop. The heat exchange module is heat exchange connected to the heat pump system 2. The medium circulation loop has an inlet and an outlet. The inlet of the medium circulation loop is communicated with the outlet of the heat exchange module, and the outlet of the medium circulation loop is communicated with the inlet of the heat exchange module. The cold or heat of the secondary refrigerant in the medium circulation loop can be released to the indoor space where the indoor terminal equipment 31 is located.

[0054] Among them, there can be one or more indoor terminal equipment 31. More than one indoor terminal equipment 31 can be distributed in different indoor spaces. The heat exchange types of the indoor terminal equipment 31 in different indoor spaces can be the same or different. Based on this, the cold or heat carried by the medium in the medium circulation loop can be used to adjust the environmental temperatures of more than one indoor space.

[0055] In this embodiment, the indoor terminal equipment 31 is a radiant terminal equipment, such as a radiant panel, a capillary tube network, etc. The radiant terminal equipment can be installed on the wall surface (including the wall surface and / or the ground surface, etc.) of the indoor space. In other embodiments, the indoor terminal equipment 31 can also be a convective heat exchange equipment. For example, the indoor terminal equipment 31 can include a fan coil unit, a floor heating coil, an air handling unit or a radiator, etc.

[0056] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop. The refrigerant circulation loop includes a compressor, a first heat exchanger, a throttling device and a second heat exchanger. The second heat exchanger is heat exchange connected to the heat exchange module in the secondary 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.

[0057] The heat pump system 2 can have two operating modes: a refrigeration mode and a heating mode. When the heat pump system 2 operates in the refrigeration mode, the second heat exchanger is in an evaporation state to absorb heat. When the heat pump system 2 operates in the heating mode, the second heat exchanger is in a condensation state to release heat.

[0058] 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 into the air in the indoor space, so as to adjust the environmental temperature of the indoor space. The medium after releasing 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 for heat exchange. In this way, the environmental control device can adjust the temperature of the indoor space.

[0059] When the heat pump system 2 operates in the cooling mode, the second heat exchanger is in the evaporation state. The medium in the heat exchange module absorbs the cold released by the second heat exchanger and its temperature decreases to form a medium carrying cold. The medium carrying cold enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold into the indoor space, and the environmental temperature of the indoor space decreases.

[0060] When the heat pump system 2 operates in the heating mode, the second heat exchanger is in the condensation state. The medium in the heat exchange module absorbs the heat released by the second heat exchanger and its temperature increases to form a medium carrying heat. The medium carrying heat enters the medium circulation loop and flows to the indoor terminal device 31, releasing heat into the indoor space, and the environmental temperature of the indoor space increases.

[0061] In other embodiments, the environmental control device may not be provided with a secondary refrigerant circulation system, and the indoor terminal device may be built into the heat pump system.

[0062] Furthermore, in this embodiment, the secondary refrigerant circulation system 3 further includes a fluid regulation module 32. The fluid regulation module 32 is connected to the control device 1. The fluid regulation module 4 can be used to regulate the collection and distribution of the supply liquid and return liquid, flow rate regulation and control in the secondary refrigerant circulation system 3. Specifically, both the heat exchange module and the indoor terminal device 31 are connected to the fluid regulation module 32. In this embodiment, the number of indoor terminal devices 31 is at least two. At least two indoor terminal devices 31 and the heat exchange module are both connected to the fluid regulation module 32. The fluid regulation module 32 includes at least two fluid valves, and the fluid valves are connected to the indoor terminal devices 31 in one-to-one correspondence. In this embodiment, the fluid regulation module 4 is a manifold. In other embodiments, the fluid regulation module 32 can also be a circulation pump.

[0063] Furthermore, in this embodiment, referring to Figure 2 , the control device 1 can also be connected to the environmental detection module 5. The environmental detection module 5 can include an indoor temperature sensor and / or an outdoor temperature sensor. The indoor temperature sensor can detect the environmental temperature of the indoor space adjusted by the environmental control device; the outdoor temperature sensor can detect the environmental temperature of the outdoor space where the environmental control device is located.

[0064] Further, in this embodiment, referring to Figure 2 , the control device 1 may also be connected to a temperature sensor 6, which is provided on the indoor wall surface where the indoor terminal device is located, for detecting the temperature of the wall surface where the indoor terminal device is installed.

[0065] In the embodiment of the present invention, referring to Figure 2 , the control device 1 includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. Each component in the control device 1 is connected through a communication bus. The memory 1002 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 may also be a storage device independent of the aforementioned processor 1001.

[0066] Those skilled in the art can understand that Figure 2 the device structure shown in

[0067] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine some components, or arrange different components. Figure 2 As shown in Figure 2 , the memory 1002, as a storage medium, may include a control program for the environmental control device. In the device shown in

[0068] the processor 1001 may be used to call the control program for the air conditioning system stored in the memory 1002 and execute the relevant step operations of the control method for the air conditioning system in the following embodiments.

[0068] The embodiment of the present invention also provides a control method for an air conditioning system, which is applied to the air conditioning system.

[0069] Referring to Figure 3 , an embodiment of the control method for the air conditioning system of the present application is proposed. In this embodiment, the air conditioning system includes a dehumidifier and an environmental control device, the environmental control device includes a heat pump system and an indoor terminal device, the indoor terminal device is used to adjust the indoor space by using the energy of the heat pump system, and the control method for the air conditioning system includes:

[0070] Step S10, obtaining a first condensation state parameter of the indoor space where the indoor terminal device is located;

[0071] The first condensation state parameter may include environmental parameters of the indoor space and / or state parameters of the indoor terminal device and / or detection data of the wall surface of the indoor space, etc.

[0072] The first condensation state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy value data, temperature data of the wall where the indoor terminal device is installed, coolant temperature data related to the indoor terminal device, temperature data of the wall where the indoor terminal device is installed, etc.

[0073] Wherein, the number of indoor terminal devices is more than one, and different indoor terminal devices are arranged in different indoor spaces, then more than one set of first condensation state parameters corresponding to different indoor spaces can be obtained.

[0074] Step S20, when the first condensation state parameter meets the first condition for the indoor space to have a condensation risk, control the dehumidifier to operate for dehumidification, and obtain the second condensation state parameter of the indoor space;

[0075] The first condition is specifically the condition that the first condensation state parameter needs to meet when the wall of the indoor space has a condensation risk. The first condition may include the target parameter range that the first condensation state parameter needs to reach or the target relationship with the preset parameter.

[0076] The operating parameters of the dehumidifier for dehumidification operation can be pre-set fixed parameters. In this embodiment, the dehumidifier is controlled to operate for dehumidification with the preset maximum dehumidification capacity. In other embodiments, the target operating parameters of the dehumidifier here can also be determined according to the parameters determined by the actual environmental state of the indoor space, according to the difference between the current humidity and the target humidity of the indoor space, and the temperature difference value between the current temperature and the preset comfortable temperature of the indoor space. The dehumidifier is controlled to operate for dehumidification according to the target operating parameters, which is beneficial to energy saving of the air conditioning system while meeting the dehumidification demand and the indoor comfort demand.

[0077] Wherein, the number of indoor terminal devices is more than one, and different indoor terminal devices are arranged in different indoor spaces. The dehumidifier corresponding to the indoor space that meets the first condition can be controlled to operate for dehumidification, and the dehumidifier corresponding to the indoor space that does not meet the first condition can be controlled to be turned off.

[0078] After the dehumidifier operates for dehumidification for a preset duration, the second condensation state parameter is obtained.

[0079] The second condensation state parameter may include the environmental parameters of the indoor space and / or the state parameters of the indoor terminal device and / or the detection data of the wall of the indoor space, etc.

[0080] The second condensation state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy value data, temperature data of the wall where the indoor terminal device is installed, coolant temperature data related to the indoor terminal device, wall temperature of the indoor space (such as the temperature of the wall where the indoor terminal device is installed), etc.

[0081] When the number of indoor spaces that meet the first condition is more than one, the second condensation state parameter of each indoor space that meets the first condition can be obtained.

[0082] Step S30, when the second condensation state parameter meets the second condition for the increased condensation risk of the indoor space, control the environmental conditioning device to operate in the moisture-proof mode.

[0083] The second condition is specifically the condition that the second condensation state parameter needs to meet when the condensation risk of the wall surface of the indoor space increases. The second condition may include the target parameter range that the second condensation state parameter needs to reach or the target relationship with the preset parameter.

[0084] During the process of the environmental conditioning device operating in the moisture-proof mode, the heat pump system operates in the cooling mode or the heating mode, and the indoor terminal device reduces the condensation risk of the indoor space through the cold or heat provided by the heat pump system.

[0085] The operating parameters during the operation of the environmental conditioning device can be pre-set fixed parameters or parameters determined according to the actual situation. For example, the target operating parameters of the dehumidifier here can be determined according to the difference between the current humidity and the target humidity of the indoor space, and the temperature difference between the current temperature and the preset comfortable temperature of the indoor space, and so on.

[0086] During the process of the environmental conditioning device operating in the moisture-proof mode, the dehumidifier maintains the dehumidification operation.

[0087] In this embodiment, when the number of indoor spaces that meet the first condition is more than one, the environmental conditioning device can be controlled to operate in the moisture-proof mode to prevent the indoor spaces that meet the second condition from condensing, and the environmental conditioning device can be controlled to stop the moisture-proof operation for the indoor spaces that do not meet the second condition.

[0088] A control method for an air conditioning system proposed in an embodiment of the present invention. When it is determined that there is a condensation risk in the indoor space through the first condensation state parameter, the dehumidifier is first used for dehumidification operation. When it is determined through the second condensation state parameter during the dehumidification operation of the dehumidifier that the condensation risk in the indoor space rises, the environmental conditioning device provided with the heat pump system and the indoor terminal device is used to operate in the moisture-proof mode to dehumidify the indoor space. Compared with the method of directly operating the environmental conditioning device in the moisture-proof mode when there is a moisture-proof requirement, the duration of the environmental conditioning device operating in the moisture-proof mode can be effectively shortened to achieve the same moisture-proof effect, thereby ensuring the indoor moisture-proof effect while improving the indoor comfort, and also preventing the indoor terminal device (especially the radiation terminal device) from condensing.

[0089] Further, in this embodiment, when the second condensation state parameter does not meet the second condition, the environmental conditioning device can be controlled to stop operating in the moisture-proof mode. Specifically, the environmental conditioning device can be controlled to stop.

[0090] Further, in this embodiment, the first condition includes that the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is less than a first preset value;

[0091] The second condition includes that the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is less than a second preset value;

[0092] Wherein, the temperature parameter represents the wall temperature of the indoor space, and the second preset value is less than the first preset value.

[0093] In this embodiment, the temperature parameter representing the wall temperature of the indoor space is the temperature of the wall where the indoor terminal device is installed. In other embodiments, the temperature parameter representing the wall temperature of the indoor space may also be the liquid inlet temperature or the surface temperature of the indoor terminal device.

[0094] The dew point temperature can be specifically obtained by detecting the indoor temperature and indoor humidity and then calculating. The surface temperature can be specifically detected by a temperature sensor provided on the surface of the indoor terminal device.

[0095] The first preset value can be less than or equal to 0 or greater than 0 and the difference from 0 is less than a preset threshold.

[0096] In this embodiment, the temperature difference value between the temperature parameter representing the wall temperature of the indoor space and the dew point temperature can accurately reflect the indoor condensation risk. Based on this, setting the first condition and the second condition in the above manner can accurately determine whether there is a condensation risk in the indoor space and whether the condensation risk deteriorates, so as to realize the precise control of the moisture-proof operation of the air conditioning system, further ensure the moisture-proof effect and improve the indoor comfort at the same time.

[0097] In other embodiments, the first condition may also include that the humidity of the indoor space is greater than a preset humidity and the temperature of the indoor space is higher than the preset humidity. The second condition may also include that the decreasing amplitude of the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is greater than a preset amplitude.

[0098] Further, in this embodiment, the control method of the air conditioning system further includes: when the indoor terminal device is in a preset state and the moisture-proof function is turned on, performing the step of obtaining the first condensation state parameter of the indoor space where the indoor terminal device is located.

[0099] The preset state here includes but is not limited to the following: refrigeration mode, air supply mode, shutdown state, standby state, etc. When the indoor terminal device is in the shutdown state or standby state, the heat pump system can be in the heating mode or the refrigeration mode.

[0100] In this embodiment, when the indoor terminal device is in a preset state, it indicates that there is no heating demand in the indoor space. At this time, directly turning on the heat pump system for heating and dehumidification has a relatively high risk of affecting user comfort. Therefore, when there is a risk of condensation at this time, a dehumidifier is preferentially used for dehumidification. When the dehumidification capacity of the dehumidifier is insufficient, the environmental control device is further used for heating and dehumidification, so as to ensure the moisture-proof effect while further reducing the impact on the comfort of indoor users.

[0101] In other embodiments, step S10 may also be executed during the process of the heat pump system operating in the heating mode.

[0102] Further, in this embodiment, when the preset function of the air conditioning system is in the on state, step S10 is executed.

[0103] The preset function here is specifically the moisture-proof function. The preset function can be turned on or off in response to a user instruction.

[0104] When the preset function is turned off, even if the first state parameter meets the condensation condition, the environmental control device can be controlled to prohibit entering the moisture-proof mode.

[0105] Specifically, when the preset function is turned on and the heat pump system is in a state other than the heating mode, step S10 is executed.

[0106] In this embodiment, when the preset function is turned on, the air conditioning system will automatically perform moisture-proof control based on the condensation state parameter, which can ensure that the air conditioning system accurately meets the user's needs while effectively reducing the risk of indoor moisture condensation.

[0107] Further, in this embodiment, the environmental control device further includes a coolant circulation system heat-exchange connected to the heat pump system. When the second condensation state parameter meets the second condition for the increased risk of condensation in the indoor space, the steps of controlling the environmental control device to operate in the moisture-proof mode include:

[0108] When the second condensation state parameter meets the second condition, control the heat pump system to operate in heating, and control the coolant circulation system to transfer the heat of the heat pump system to the indoor terminal device.

[0109] When the coolant circulation system is operating, in one implementation, the fluid adjustment module in the coolant circulation system can be controlled to operate to adjust the amount of coolant flowing into the indoor terminal device from the heat exchange module. In another implementation, the convection adjustment module (such as a fan, etc.) in the indoor terminal device of the coolant circulation system can be controlled to operate to adjust the amount of liquid flowing through the heat exchange of the indoor terminal device.

[0110] The operating parameters during the heating operation of the heat pump system and / or during the operation of the secondary refrigerant circulation system can be preset fixed parameters or can be operating parameters determined according to the actual operating state of the environmental conditioning equipment.

[0111] When the heat pump system is operating in heating mode, the second heat exchanger in the heat pump system is in a condensing state. When the secondary refrigerant circulation system is operating, the medium in the heat exchange module absorbs the heat output by the second heat exchanger and then its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the indoor terminal equipment, and the heat released by the indoor terminal equipment can effectively increase the wall temperature of the indoor space.

[0112] In this embodiment, through the coordinated operation of the heat pump system and the secondary refrigerant circulation system, the heat released by the indoor terminal equipment can effectively increase the wall temperature of the installed indoor space, prevent condensation on the inner space wall surface, and effectively and timely reduce the risk of indoor moisture condensation.

[0113] Furthermore, in this embodiment, the number of the indoor terminal equipment is more than one, and different indoor terminal equipment are arranged in different indoor spaces. When the second condensation state parameter meets the second condition, the steps of controlling the heat pump system to operate in heating mode and controlling the secondary refrigerant circulation system to transport the heat of the heat pump system to the indoor terminal equipment include:

[0114] When the second condensation state parameter meets the second condition, control the heat pump system to operate in heating mode, and control the secondary refrigerant circulation system to transport the heat of the heat pump system to the indoor terminal equipment in the indoor space that meets the second condition and stop transporting the heat of the heat pump system to the indoor terminal equipment in the indoor space that does not meet the second condition.

[0115] When the second condensation state parameter meets the second condition, the indoor space corresponding to the second condensation state parameter meets the second condition.

[0116] In this embodiment, the second condensation state parameter of each indoor space that meets the first condition can be obtained. When there is a second condensation state parameter that meets the second condition, the heat pump system can be turned on to the heating mode. When the indoor terminal device in the indoor space that meets the second condition is a radiant terminal device, the fluid valve corresponding to the indoor terminal device in the indoor space that meets the second condition can be controlled to open. When the indoor terminal device in the indoor space that meets the second condition is a convective heat exchange device, the indoor fan in the convective heat exchange device in the indoor space that meets the second condition can be controlled to turn on. When the indoor terminal device in the indoor space that does not meet the second condition is a radiant terminal device, the fluid valve corresponding to the indoor terminal device in the indoor space that does not meet the second condition can be controlled to close. When the indoor terminal device in the indoor space that does not meet the second condition is a convective heat exchange device, the indoor fan in the convective heat exchange device in the indoor space that does not meet the second condition can be controlled to turn off.

[0117] In this embodiment, through the above method, when the environmental conditioning device adjusts more than one indoor space, it can avoid heating the indoor space with a lower condensation risk, ensure the moisture-proof effect of each indoor space, and effectively improve the comfort of each indoor space while taking it into account.

[0118] Further, based on the above embodiment, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, referring to Figure 4 , step S31 is defined as when the second condensation state parameter meets the second condition, controlling the heat pump system to operate in heating mode, and controlling the secondary refrigerant circulation system to transfer the heat of the heat pump system to the indoor terminal device. After step S31, it further includes:

[0119] Step S40, obtaining the third condensation state parameter of the indoor space;

[0120] The third condensation state parameter may include environmental parameters of the indoor space and / or state parameters of the indoor terminal device and / or detection data of the wall surface of the indoor space, etc.

[0121] The third condensation state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy value data, temperature data of the wall surface where the indoor terminal device is installed, secondary refrigerant temperature data related to the indoor terminal device, wall temperature of the indoor space (for example, the temperature of the wall surface where the indoor terminal device is installed), etc.

[0122] Wherein, when the number of indoor spaces that meet the second condition is more than one, the third condensation state parameter of each indoor space that meets the second condition can be obtained.

[0123] Step S50, when the third condensation state parameter meets the third condition, control the heat pump system to stop heating operation and / or control the secondary refrigerant circulation system to stop delivering the heat of the heat pump system to the indoor terminal equipment; wherein, the third condition indicates that the condensation risk in the indoor space decreases and / or the temperature in the indoor space deviates from comfort.

[0124] Specifically, the third condition is the condition that the third condensation state parameter needs to meet when the condensation risk on the wall surface of the indoor space decreases or the temperature in the indoor space deviates from comfort. The third condition may include the target parameter range that the third condensation state parameter needs to reach or the target relationship with the preset parameter.

[0125] When the third condensation state parameter meets the third condition, in addition to controlling the operation of the environmental conditioning equipment in the above manner, control the dehumidifier to maintain dehumidification operation.

[0126] In this embodiment, when it is determined through the third condensation state parameter that the condensation risk in the indoor space decreases or affects indoor comfort, stop delivering heat to the indoor terminal equipment, avoiding excessive temperature rise in the space where the indoor terminal equipment is located, thereby ensuring the moisture-proof effect while improving the comfort of the indoor space.

[0127] Further, in this embodiment, the number of the indoor terminal equipment is more than one, and different indoor terminal equipment are arranged in different indoor spaces. The step of when the third condensation state parameter meets the third condition, controlling the heat pump system to stop heating operation and / or controlling the secondary refrigerant circulation system to stop delivering the heat of the heat pump system to the indoor terminal equipment includes:

[0128] When some of the third condensation state parameters meet the third condition, control the heat pump system to maintain heating operation, control the secondary refrigerant circulation system to stop delivering the heat of the heat pump system to the indoor terminal equipment in the first indoor space, and control the secondary refrigerant circulation system to maintain delivering the heat of the heat pump system to the indoor terminal equipment in the second indoor space;

[0129] When all of the third condensation state parameters meet the third condition, control the heat pump system to stop heating operation, and control the secondary refrigerant circulation system to stop delivering the heat of the heat pump system to all the indoor terminal equipment in the first indoor space;

[0130] Wherein, the third condensation state parameter corresponding to the first indoor space meets the third condition, and the third condensation state parameter corresponding to the second indoor space does not meet the third condition.

[0131] In this embodiment, the third condensation state parameter of each indoor space that meets the second condition is obtained. When the third condensation state parameter meets the third condition, the corresponding indoor space is the first indoor space; when the third condensation state parameter does not meet the third condition, the corresponding indoor space is the second indoor space.

[0132] When the indoor terminal device in the indoor space that meets the third condition is a radiant terminal device, the fluid valve corresponding to the indoor terminal device in the indoor space that meets the third condition can be controlled to close. When the indoor terminal device in the indoor space that meets the third condition is a convective heat exchange device, the indoor fan in the convective heat exchange device in the indoor space that meets the third condition can be controlled to close; when the indoor terminal device in the indoor space that does not meet the third condition is a radiant terminal device, the fluid valve corresponding to the indoor terminal device in the indoor space that does not meet the third condition can be controlled to remain open. When the indoor terminal device in the indoor space that does not meet the third condition is a convective heat exchange device, the indoor fan in the convective heat exchange device in the indoor space that does not meet the third condition can be controlled to remain open.

[0133] In this embodiment, through the above method, it can be ensured that when the environmental conditioning equipment adjusts more than one indoor space, each indoor space can prevent excessive heating capacity while ensuring the moisture-proof effect, thereby effectively improving the moisture-proof effect and thermal comfort of each indoor space.

[0134] Further, in this embodiment, the third condition includes at least one of the following conditions:

[0135] Condition 3, the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is greater than or equal to a third preset value, and the temperature parameter represents the wall temperature of the indoor space;

[0136] Condition 4, the temperature rise value of the indoor space is greater than the target change value.

[0137] In this embodiment, the temperature parameter representing the wall temperature of the indoor space is the temperature of the wall where the indoor terminal device is installed. In other embodiments, the temperature parameter representing the wall temperature of the indoor space may also be the inlet liquid temperature or surface temperature of the indoor terminal device.

[0138] The dew point temperature can be specifically obtained by detecting the indoor temperature and indoor humidity and then calculating. The surface temperature can be specifically detected by a temperature sensor provided on the surface of the indoor terminal device.

[0139] The third preset value is greater than the above-mentioned second preset value.

[0140] Obtain the first indoor temperature of the indoor space at the current moment and the second indoor temperature of the indoor space when the environmental conditioning equipment starts the moisture-proof mode, and determine the temperature rise value here according to the difference between the first indoor temperature and the second indoor temperature.

[0141] The target change value is specifically a critical value used to distinguish whether the indoor temperature is comfortable after starting the moisture-proof mode. The target change value can be a preset fixed value or a value determined according to the actual operating conditions of the environmental control device. In this embodiment, in order to accurately characterize the indoor thermal comfort, the target change value includes the temperature rise amplitude of the outdoor environment where the environmental control device is located after starting the moisture-proof mode. Specifically, the first outdoor temperature of the current outdoor environment and the second outdoor temperature of the outdoor environment when the heat pump system starts heating operation are obtained, and the target change value here is determined according to the temperature difference value between the first outdoor temperature and the second outdoor temperature.

[0142] In this embodiment, condition 4 may include that the temperature difference value between the first indoor temperature and the second indoor temperature is greater than the temperature difference value between the first outdoor temperature and the second outdoor temperature.

[0143] In this embodiment, when the third condensation state parameter satisfies condition 3 and lasts for a preset duration, or when the third condensation state parameter satisfies condition 4, control the heat pump system to stop heating operation and / or control the coolant circulation system to stop delivering the heat of the heat pump system to the indoor terminal device.

[0144] In this embodiment, through the above method, the indoor moisture-proof effect can be guaranteed while ensuring the indoor temperature comfort.

[0145] In other embodiments, the third condition may also include that the heating duration of the indoor terminal device in the indoor space satisfying the second condition reaches a preset duration. Or, the third condition may also include that the increase amplitude of the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is greater than a preset amplitude.

[0146] Further, based on any of the above embodiments, another embodiment of the control method of the air conditioning system of the present application is proposed. In this embodiment, referring to Figure 5 , after step S50, the following is further included:

[0147] Step S60, obtaining the fourth condensation state parameter of the indoor space;

[0148] The fourth condensation state parameter may include environmental parameters of the indoor space and / or state parameters of the indoor terminal device and / or detection data of the wall surface of the indoor space, etc.

[0149] The fourth condensation state parameter may include at least one of the following: indoor temperature data, indoor humidity data, indoor enthalpy value data, temperature data of the wall surface where the indoor terminal device is installed, coolant temperature data related to the indoor terminal device, wall surface temperature of the indoor space (such as the temperature of the wall surface where the indoor terminal device is installed), etc.

[0150] When the number of indoor spaces satisfying the first condition is more than one, the fourth condensation state parameter of each indoor space satisfying the first condition can be obtained.

[0151] Step S70, when the fourth condensation state parameter satisfies the fourth condition for the condensation risk in the indoor space to decrease, control the dehumidifier to stop operating.

[0152] The fourth condition is specifically the condition that the fourth condensation state parameter needs to satisfy when the condensation risk on the wall surface of the indoor space is further reduced. The fourth condition indicates that there is no condensation risk in the corresponding indoor space. The fourth condition may include the target parameter range that the fourth condensation state parameter needs to reach or the target relationship with the preset parameter.

[0153] Among them, when the fourth condensation state parameter does not satisfy the fourth condition, control the dehumidifier to maintain the dehumidification operation.

[0154] In this embodiment, through the above method, it is beneficial to ensure the indoor moisture-proof effect on the basis of the indoor temperature meeting the user's comfort.

[0155] Further, in this embodiment, the number of the indoor terminal devices is more than one, different indoor terminal devices are arranged in different indoor spaces, the dehumidifier is used to adjust the humidity of at least two indoor spaces, and the step of controlling the dehumidifier to stop operating when the fourth condensation state parameter satisfies the fourth condition for the condensation risk in the indoor space to decrease includes: when the fourth condensation state parameters of all the indoor spaces satisfy the fourth condition, control the dehumidifier to stop.

[0156] Among them, when the fourth condensation state parameters of some indoor spaces do not satisfy the fourth condition, the dehumidifier can be controlled to maintain the dehumidification operation.

[0157] In this embodiment, through the above method, it is beneficial to ensure the moisture-proof effect of each indoor space on the basis of the indoor temperature of each indoor space meeting the user's comfort.

[0158] Further, in this embodiment, the fourth condition includes that the temperature difference value between the temperature parameter and the dew point temperature of the indoor space is greater than or equal to the fourth preset value, and the temperature parameter represents the wall temperature of the indoor space.

[0159] In this embodiment, the temperature parameter representing the wall temperature of the indoor space is the temperature of the wall where the indoor terminal device is installed. In other embodiments, the temperature parameter representing the wall temperature of the indoor space may also be the inlet liquid temperature or the surface temperature of the indoor terminal device.

[0160] The dew point temperature can be specifically calculated by detecting the indoor temperature and indoor humidity.

[0161] The surface temperature can be specifically detected by a temperature sensor provided on the surface of the indoor terminal device.

[0162] The fourth preset value is greater than the third preset value. In this embodiment, the fourth preset value is greater than 0.

[0163] In this embodiment, the temperature difference value between the surface temperature and the dew point temperature can accurately reflect the indoor condensation risk. When this temperature difference value is large enough, it can be considered that there is no condensation risk in the corresponding indoor space, so as to ensure the moisture-proof effect of the indoor space while the dehumidifier can be timely turned off to save energy consumption.

[0164] In other embodiments, the fourth condition may also include that the operation duration of the dehumidifier is greater than or equal to the target duration, and the target duration can be determined according to the total duration of the moisture-proof mode of the environmental conditioning device and the humidity difference between the initial humidity and the target humidity of the indoor space when the dehumidifier is turned on.
