[0057] It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0058] An embodiment of the present invention provides an environmental conditioning device, specifically for conditioning the air in an indoor environment.

[0059] In an embodiment of the present invention, referring to Figure 1 and Figure 2 , the environmental conditioning device includes a control device 1 and a secondary refrigerant circulation system 3. The secondary refrigerant circulation system 3 includes at least two indoor terminal devices 31. Different indoor terminal devices are arranged in different indoor spaces. The secondary refrigerant circulation system 3 is connected to the control device 1.

[0060] The secondary refrigerant circulation system 3 circulates the secondary refrigerant to deliver the energy output by the heat pump system into the indoor space to adjust the temperature of the indoor space.

[0061] 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, and the secondary refrigerant circulation system 3 can use the indoor terminal device 31 to adjust the indoor temperature. In an embodiment of the present invention, the water supply temperature of the secondary refrigerant circulation system 3 can be understood as the outlet water 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.

[0062] The heat exchange types of the indoor terminal devices 31 in different indoor spaces can be the same or different.

[0063] In this embodiment, the indoor terminal device 31 is a radiant terminal device, such as a radiant panel, a capillary tube network, etc. The radiant terminal device can be installed on the wall surface of the indoor space (including the wall surface and / or the ground surface, etc.). In other embodiments, the indoor terminal device 31 can also be a convective heat exchange device. For example, the indoor terminal device 31 can include a fan coil unit, a floor heating coil, an air handling unit, or a radiator, etc.

[0064] Furthermore, 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, flow rate regulation, and control of the supply liquid and return liquid 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 a 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.

[0065] Further, in this embodiment, referring to Figure 1 and Figure 2 , the environmental conditioning device includes a heat pump system 2, a secondary refrigerant circulation system 3 is heat exchange connected to the heat pump system 2, and both the heat pump system 2 and the secondary refrigerant circulation system 3 are connected to the control device 1. The heat pump system 2 is used to provide energy (such as cooling capacity or heating capacity) for the heat exchange between the secondary refrigerant circulation system 3 and the indoor space.

[0066] 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.

[0067] The secondary refrigerant circulation system 3 includes a medium circulation loop and indoor terminal devices 31 and heat exchange modules provided in the medium circulation loop. The heat exchange modules are 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 cooling capacity or heating capacity of the secondary refrigerant in the medium circulation loop can be released to the indoor space where the indoor terminal device 31 is located. Based on this, the cooling capacity or heating capacity carried by the medium in the medium circulation loop can be used to adjust the environmental temperature of more than one indoor space.

[0068] 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 double-pipe heat exchanger or a plate heat exchanger.

[0069] 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.

[0070] During the operation of the heat pump system 2, the water in the heat exchange module can absorb the cooling capacity or heating capacity released by the second heat exchanger to form cold water or hot water. The medium flowing out of the heat exchange module carrying the cooling capacity or heating capacity can enter the medium circulation loop and flow to the indoor terminal device 31 to release the cooling capacity or heating capacity into the air in the indoor space to adjust the environmental temperature of the indoor space. The medium after releasing the cooling capacity or heating capacity 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 cycle is repeated, so as to realize the adjustment of the indoor space temperature by the environmental conditioning device.

[0071] 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 energy output by the second heat exchanger and its temperature drops, forming a medium carrying cold energy. The medium carrying cold energy enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold energy into the indoor space, and the environmental temperature of the indoor space decreases.

[0072] 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 energy output by the second heat exchanger and its temperature rises, forming a medium carrying heat energy. The medium carrying heat energy enters the medium circulation loop and flows to the indoor terminal device 31, releasing heat energy into the indoor space, and the environmental temperature of the indoor space increases.

[0073] In other embodiments, in addition to the heat pump system 2, the secondary refrigerant circulation system 3 can also be heat exchange-connected with other energy-releasing devices, such as electric heating devices, energy storage devices, etc.

[0074] 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 indoor sensors and / or outdoor sensors. The indoor sensors can detect the environmental parameters (temperature, humidity, enthalpy value, etc.) of the indoor space regulated by the environmental conditioning equipment; the outdoor temperature sensors can detect the environmental parameters (temperature, humidity, enthalpy value, etc.) of the outdoor space where it is located.

[0075] Furthermore, in this embodiment, referring to Figure 2 , the control device 1 can also be connected to the temperature detection module 6. The temperature detection module 6 is provided on the wall where the indoor terminal device 31 is installed and / or on the secondary refrigerant flow path (the outlet flowing into the heat exchange module or the liquid inlet of the indoor terminal device 31) connected to the indoor terminal device 31, so as to detect the temperature of the wall where the indoor terminal device 31 is installed and / or the secondary refrigerant temperature.

[0076] In the embodiment of the present invention, referring to Figure 2 , the control device 1 of the environmental conditioning equipment 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 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0077] Those skilled in the art can understand that Figure 2 the device structure shown in

[0078] As Figure 2 shown, the memory 1002, as a storage medium, may include a control program for the environmental control device. In the Figure 2 device shown, the processor 1001 may be used to call the control program for the environmental control device stored in the memory 1002 and perform the relevant step operations of the control method for the environmental control device in the following embodiments.

[0079] An embodiment of the present invention also provides a control method for an environmental control device, which is applied to the above environmental control device.

[0080] Referring to Figure 3 , an embodiment of the control method for the environmental control device of the present application is proposed. In this embodiment, the environmental control device includes a refrigerant circulation system, and the refrigerant circulation system includes indoor terminal equipment. The control method for the environmental control device includes:

[0081] Step S10, obtaining user demand parameters and status parameters of the indoor terminal equipment;

[0082] The user demand parameters are parameters representing the user's demand for setting the target refrigerant temperature. The user demand parameters may include at least one of the following: whether there is a demand for automatically setting the refrigerant temperature, the target temperature of the refrigerant set by the user himself, the target environmental temperature of the space where the indoor terminal equipment is located set by the user himself, and so on. The user demand parameters may be determined according to the parameters input by the user or by monitoring the user status in the indoor space.

[0083] The status parameters are parameters representing the actual operating conditions of the indoor terminal equipment in the indoor space. The status parameters may include the status parameters of the indoor terminal equipment itself (parameters representing the inherent attributes of the equipment and / or parameters obtained by detecting the equipment status, etc.) and / or the environmental status parameters of the space where the indoor terminal equipment is located. The status parameters may be detected by sensors provided on the surface of the indoor terminal equipment or in the refrigerant flow path and / or by an environmental detection module provided in the space where the indoor terminal equipment is located.

[0084] Step S20, determining the target refrigerant temperature of the refrigerant circulation system according to the user demand parameters and the status parameters;

[0085] The target refrigerant temperature is the target temperature that the refrigerant in the refrigerant circulation system needs to reach. The target refrigerant temperature may include the target inlet temperature of the indoor terminal equipment or the target outlet temperature of the heat exchange module.

[0086] Different user demand parameters and different state parameters correspond to different target secondary refrigerant temperatures. The correspondence relationship between the user demand parameters, state parameters and the target secondary refrigerant temperature can be preset. The correspondence relationship can include forms such as calculation relationships, mapping relationships, machine learning models, etc. Based on this correspondence relationship, the target secondary refrigerant temperature corresponding to the current user demand parameters and state parameters can be determined.

[0087] Specifically, the user demand parameters and state parameters can be substituted into a preset formula to calculate the target secondary refrigerant temperature. Or, determine the first parameter interval where the user demand parameters are located and the second parameter interval where the state parameters are located, and determine the target secondary refrigerant temperature here according to the first parameter interval and the second parameter interval.

[0088] Step S30, control the operation of the environmental conditioning device according to the target secondary refrigerant temperature.

[0089] Obtain the current liquid inlet temperature of the indoor terminal device, and control the operation of the environmental conditioning device according to the temperature difference value between the liquid inlet temperature and the target secondary refrigerant temperature. Specifically, at least one of the following components can be controlled according to the temperature difference value: the compressor in the heat pump system, the fluid valve corresponding to the indoor terminal device, the indoor fan in the indoor terminal device, the throttling device in the heat pump system, the circulation pump in the secondary refrigerant circulation system, and so on.

[0090] For example, when the heat pump system operates in the refrigeration mode, when the liquid inlet temperature of the indoor terminal device is less than or equal to the target secondary refrigerant temperature, control the fluid valve corresponding to the indoor terminal device to close; when the liquid inlet temperature of the indoor terminal device is greater than the target secondary refrigerant temperature, control the fluid valve corresponding to the indoor terminal device to open.

[0091] A control method for an environmental conditioning device proposed in an embodiment of the present invention. In this method, the target secondary refrigerant temperature is no longer a preset fixed temperature, but the target secondary refrigerant temperature of the secondary refrigerant circulation system is determined by combining user demand parameters and the state parameters of the space where the indoor terminal device is located. The state parameters can accurately reflect its operating conditions. Based on this, when controlling the environmental conditioning device according to the determined target secondary refrigerant temperature, on the basis of meeting the user's needs, the device can be accurately matched with the actual operating conditions, ensuring that the output capacity of the device when adjusting the indoor temperature will not be too large or too small, realizing refined and stable control of the indoor temperature, thereby saving equipment energy consumption and improving the comfort of indoor users.

[0092] Further, based on the above embodiment, another embodiment of the control method for the environmental conditioning device of the present application is proposed. In this embodiment, referring to Figure 4 , the step S20 includes:

[0093] Step S21, obtain a first reference temperature of the target secondary refrigerant temperature according to the user demand parameters;

[0094] In one implementation, different user demand parameters can be correspondingly associated with different preset temperatures, and the preset temperature associated with the current user demand parameter is determined as the first reference temperature.

[0095] In another implementation, different user demand parameters can correspond to different preset parameter types for determining the first reference temperature. The preset parameter type corresponding to the current user demand parameter is determined as the target type, and the first reference temperature is determined according to the target parameter corresponding to the target type.

[0096] In yet another implementation, the first reference temperature can be calculated by substituting the user demand parameter into a preset formula.

[0097] Step S22: Determine the target coolant temperature according to the state parameter and the first reference temperature.

[0098] In one implementation, a temperature correction value can be determined according to the state parameter, and the first reference temperature is corrected according to the temperature correction value to obtain the target coolant temperature.

[0099] In another implementation, a target correspondence relationship between the first reference temperature and the target coolant temperature can be determined according to the state parameter. Different state parameters correspond to different target correspondence relationships, and the target coolant temperature corresponding to the current first reference temperature can be determined based on the target correspondence relationship.

[0100] In yet another implementation, a third reference temperature can be determined according to the state parameter, and the target coolant temperature is determined according to the first reference temperature and the third reference temperature.

[0101] In this embodiment, through the above method, on the basis of ensuring user requirements, the target coolant temperature can be determined according to the actual operating conditions of the indoor terminal equipment characterized by the state parameter, thereby saving equipment energy consumption and improving indoor user comfort.

[0102] Further, in this embodiment, the step of obtaining the first reference temperature of the target coolant temperature according to the user demand parameter includes: when the user demand parameter includes the user-set coolant temperature, determining the first reference temperature according to the target temperature of the coolant set by the user; when the user demand parameter includes automatically setting the coolant temperature, determining the first reference temperature according to the environmental parameter of the environment where the environmental conditioning device is located and / or the installation information of the buffer container in the environmental conditioning device.

[0103] When the target temperature of the coolant set by the user is received, it is determined that the user demand parameter includes the user-set coolant temperature; when the target temperature of the coolant set by the user is not received, it is determined that the user demand parameter includes automatically setting the coolant temperature.

[0104] Among them, the target temperature of the secondary refrigerant set by the user can be determined as the first reference temperature, or the target temperature can be corrected according to the temperature correction value to obtain the first reference temperature. The temperature correction value here can be a preset fixed value or a value determined according to the actual operating conditions of the environmental control equipment. For example, the temperature correction value is determined according to the current operating mode of the environmental control equipment, the temperature difference between the indoor environmental temperature and the target environmental temperature, and the number of indoor terminal devices with energy demand at present, etc.

[0105] The environmental parameters include at least one of the following: environmental temperature, environmental humidity, environmental enthalpy value, etc.

[0106] The equipment status parameters include at least one of the following: installation information of the buffer container in the secondary refrigerant circulation system, operating power of the circulation pump in the secondary refrigerant circulation system, number of fluid valves opened in the secondary refrigerant circulation system, temperature status parameters of the compressor in the heat pump system, pressure status parameters of the heat pump system, etc.

[0107] Different environmental parameters and / or different equipment status parameters correspond to different first reference temperatures. The first reference temperature can be calculated by substituting the environmental parameters and / or equipment status parameters into a preset formula. It is also possible to determine the first interval where the environmental parameters are located and / or the second interval where the equipment status parameters are located, and determine the first reference temperature according to the first interval and the second interval.

[0108] In this embodiment, the environmental parameters include outdoor environmental parameters and / or indoor environmental parameters, and the equipment status parameters include the installation information of the buffer container in the secondary refrigerant circulation system. The buffer container is specifically a container that increases the capacity of the secondary refrigerant, stores cold or heat in the secondary refrigerant circulation system. For example, the buffer container is a buffer water tank. The installation information can include at least one of the following: whether the buffer container is installed in the secondary refrigerant circulation system, the capacity of the buffer container installed in the secondary refrigerant circulation system, the length of the secondary refrigerant flow path between the buffer container installed in the secondary refrigerant circulation system and the indoor terminal device, etc. Based on this, when the user demand parameter includes automatically setting the secondary refrigerant temperature, the first reference temperature can be determined in at least one of the following ways: determining the first reference temperature according to the outdoor environmental parameters; determining the first reference temperature according to the indoor environmental parameters; determining the first reference temperature according to the installation information.

[0109] In this embodiment, through the above method, when the user has clear requirements, the first reference temperature can be set according to the target temperature set by the user, which is beneficial to accurately meet the user's needs; when the user does not have clear requirements, the first reference temperature is determined according to the environmental parameters and / or equipment status parameters, which is beneficial to ensuring user comfort while improving system energy efficiency.

[0110] Further, in this embodiment, the step of determining the first reference temperature according to the environmental parameters of the environment where the environmental adjustment device is located and / or the device state parameters of the environmental adjustment device includes: when the operation duration of the environmental adjustment device in the current mode is less than or equal to a preset duration, determining the first reference temperature according to the outdoor environmental parameters; when the operation duration of the environmental adjustment device in the current mode is greater than the preset duration, determining the first reference temperature according to the indoor environmental parameters, the outdoor environmental parameters, and the installation information.

[0111] The operation duration is specifically the total duration from the moment when the environmental adjustment device starts the current mode to the current moment.

[0112] The preset duration can be a preset fixed duration or a value determined according to the actual operation situation of the environmental adjustment device. For example, the preset duration here can be determined according to the operation mode of the environmental adjustment device and the indoor-outdoor temperature difference value when the environmental adjustment device enters the current mode.

[0113] In the process of determining the first reference temperature according to the outdoor environmental parameters: the outdoor environmental parameters can be substituted into a formula to calculate the first reference temperature; the first reference temperature can also be obtained by looking up a table based on the outdoor environmental parameters; determine the parameter interval where the outdoor environmental parameters are located, and use the temperature associated with the parameter interval as the first reference temperature, and so on.

[0114] In the process of determining the first reference temperature according to the indoor environmental parameters, the outdoor environmental parameters, and the installation information: the target relationship between the indoor environmental parameters, the outdoor environmental parameters, and the first reference temperature can be determined according to the installation information. Different installation information can correspond to different target relationships. Determine the current installation information and the corresponding target relationship, and determine the first reference temperature corresponding to the current indoor environmental parameters and outdoor environmental parameters according to the determined target relationship; it is also possible to determine the characteristic parameter value corresponding to the installation information, and substitute the characteristic parameter value, the indoor environmental parameters, and the outdoor environmental parameters into a formula to calculate and obtain the first reference temperature, and so on.

[0115] In this embodiment, in the initial stage of the environmental adjustment device running in the current mode, determining the first reference temperature according to the outdoor environmental parameters is beneficial to quickly meeting the indoor comfort requirements and ensuring the operation stability and reliability of the system; in the later stage of the environmental adjustment device running in the current mode, determining the first reference temperature by combining the indoor environmental parameters, the outdoor environmental parameters, and the installation information is beneficial to ensuring the accurate matching of the output capacity of the device and the indoor comfort requirements, realizing the refined control of the indoor environment, thereby further improving the device energy efficiency while improving the indoor user comfort.

[0116] Further, in this embodiment, the indoor environmental parameters include the current parameter value of the indoor temperature difference and the parameter change value of the indoor temperature difference. The indoor temperature difference is the temperature difference value between the indoor environmental temperature and the set temperature. The outdoor environmental parameters include the outdoor environmental temperature. The step of determining the first reference temperature according to the indoor environmental parameters, the outdoor environmental parameters, and the installation information includes: determining the reference coolant temperature corresponding to the outdoor environmental temperature, and determining a first temperature correction value according to the current parameter value and the parameter change value; when the installation information includes that the buffer container is not installed, correcting the reference coolant temperature according to the current parameter value and the parameter change value to obtain the first reference temperature; when the installation information includes that the buffer container is installed, determining the first reference temperature according to the set coolant temperature of the buffer container, the current parameter value, the parameter change value, and the reference coolant temperature.

[0117] Specifically, the current parameter value can be obtained by acquiring the current indoor temperature of the indoor space where the indoor terminal device is located, taking the first difference between the current indoor temperature and the set temperature as the current parameter value, acquiring the initial indoor temperature of the indoor space where the indoor terminal device is located when the environmental conditioning device starts the current mode, determining the second difference between the initial indoor temperature and the set temperature, and determining the difference between the first difference and the second difference as the parameter change value.

[0118] The set coolant temperature is specifically the target temperature of the coolant preset in the buffer container.

[0119] In the process of determining the reference coolant temperature corresponding to the outdoor environmental temperature: the outdoor environmental temperature can be substituted into the formula to calculate the reference coolant temperature; or the reference coolant temperature here can be obtained by looking up the table according to the outdoor environmental temperature; determine the temperature range where the outdoor environmental temperature is located, and take the temperature associated with the temperature range as the reference coolant temperature, and so on. In this embodiment, when the operation duration of the environmental conditioning device in the current mode is less than or equal to the preset duration, the first reference temperature is equal to the reference coolant temperature here.

[0120] When the installation information includes that the buffer container is not installed, determine a first temperature correction value according to the current parameter value and the parameter change value, and correct the reference coolant temperature according to the first temperature correction value to obtain the first reference temperature here. The process of determining the first temperature correction value may include: substituting the current parameter value and the parameter change value into the formula to calculate the first temperature correction value; or obtaining the first temperature correction value here by looking up the table according to the current parameter value and the parameter change value; or determining the parameter ranges where the current parameter value and the parameter change value are located respectively, and determining the first temperature correction value according to the determined parameter ranges, and so on.

[0121] When the installation information includes that the buffer container has been installed, in one implementation, the second temperature correction value can be determined according to the set coolant temperature, the current parameter value, and the parameter change value, and the reference coolant temperature is corrected according to the second temperature correction value to obtain the first reference temperature here. In another implementation, the set coolant temperature, the current parameter value, and the parameter change value are directly substituted into a preset formula to calculate the first reference temperature.

[0122] In this embodiment, the installation information can accurately reflect whether there is energy stored in the system. Based on this, the current parameter value and the parameter change value can accurately reflect the actual load condition of the indoor space, and the set coolant temperature can accurately reflect the amount of energy stored in the buffer container. Based on this, when the buffer container is not installed in the system, the reference coolant temperature is adjusted according to the current parameter value and the parameter change value to obtain the first reference temperature, which is beneficial to accurately matching the energy output by the system with the actual load demand of the indoor space, realizing accurate control of the indoor temperature, and further improving the indoor comfort; when the buffer container is installed in the system, the first reference temperature is obtained by combining the current parameter value, the parameter change value, the set coolant temperature of the buffer container, and the reference coolant temperature, ensuring the effective utilization of the energy stored in the buffer container, so as to ensure that the output capacity of the equipment can be accurately matched with the actual load demand of the indoor space, realizing accurate control of the indoor temperature, and further improving the indoor comfort.

[0123] Further, in this embodiment, the step of determining the first reference temperature according to the set coolant temperature of the buffer container, the current parameter value, the parameter change value, and the reference coolant temperature includes: determining a first temperature according to the current parameter value, the parameter change value, and the reference coolant temperature, and determining a second temperature according to the set coolant temperature and the reference coolant temperature; determining the first reference temperature according to the second temperature and the first temperature.

[0124] Determine a first temperature correction value according to the current parameter value and the parameter change value, and correct the reference coolant temperature according to the first temperature correction value to obtain the first temperature here. Determine a second temperature correction value according to the set coolant temperature, and correct the reference coolant temperature according to the second temperature correction value to obtain the second temperature.

[0125] Wherein, the number of the indoor terminal devices is more than one, and different indoor terminal devices are arranged in different indoor spaces. In the process of determining the first temperature, the reference coolant temperature is corrected respectively according to the current parameter value and the parameter change value of each indoor space to obtain more than one first temperature.

[0126] When the environmental conditioning device operates in the cooling mode, the reference coolant temperature is decreased according to the current parameter value and the parameter change value to obtain a first temperature, and the reference coolant temperature is decreased according to the set coolant temperature to obtain a second temperature. The second temperature correction value is greater than or equal to 0.

[0127] When the environmental conditioning device operates in the heating mode, the reference coolant temperature is increased according to the current parameter value and the parameter change value to obtain a first temperature, and the reference coolant temperature is increased according to the set coolant temperature to obtain a second temperature.

[0128] In one implementation, one of the first temperature and the second temperature is determined as a first reference temperature according to the magnitude relationship between the first temperature and the second temperature. If the number of indoor terminal devices is one, the minimum value of the first temperature and the second temperature can be determined as the first reference temperature. When the number of indoor terminal devices is more than one, the reference coolant temperature is respectively corrected according to the current parameter value and the parameter change value of each indoor space to obtain more than one first temperature, where one indoor space corresponds to one first temperature. In this embodiment, when the environmental conditioning device operates in the cooling mode, the minimum value of the second temperature and more than one first temperature is determined as the first reference temperature. Among them, in the cooling mode, the indoor terminal device is in a heat absorption state. In other embodiments, the average value of more than one first temperature can also be determined, and the average value and the minimum value of the second temperature are used as the first reference temperature. When the environmental conditioning device operates in the heating mode, the maximum value of the second temperature and more than one first temperature can also be determined as the first reference temperature.

[0129] In another implementation, the first reference temperature is calculated by combining the first temperature and the second temperature. For example, the average value of the first temperature and the second temperature is used as the first reference temperature; the environmental temperature of the environment where the buffer container is located can also be obtained, the first weight value corresponding to the first temperature and the second weight value corresponding to the second temperature are determined according to the environmental temperature, and the first reference temperature is calculated by performing weighted average calculation on the first temperature and the second temperature according to the first weight value and the second weight value.

[0130] In this embodiment, through the above method, it is beneficial to improve the accuracy of the above first reference temperature, so as to improve the comfort of indoor users while improving the system energy efficiency. Among them, when the environmental conditioning device adjusts more than one indoor space, combining the first temperature corresponding to more than one indoor space and the second temperature corresponding to the buffer container to determine the first reference temperature is beneficial to improving the cooling comfort of each indoor space. Among them, when the environmental conditioning device operates in the cooling mode, taking the minimum value of the first temperature and the second temperature as the first reference temperature is beneficial to further ensuring that the environmental conditioning device outputs sufficient cooling capacity to meet the cooling comfort of the indoor environment.

[0131] 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. In this embodiment, the state parameters include the terminal type and the condensation state parameter of the space where the indoor terminal device is located. Referring to Figure 5 , the step of determining the target coolant temperature according to the state parameters and the first reference temperature includes:

[0132] Step S221, when the environmental conditioning device operates in the cooling mode and the terminal type is other than the radiant terminal device, determine the first reference temperature as the target coolant temperature;

[0133] Step S222, when the environmental conditioning device operates in the cooling mode and the terminal type is the radiant terminal device, or when the environmental conditioning device operates in the cooling mode, the terminal type is the radiant terminal device, and the condensation state parameter meets the preset condensation condition, determine the second reference temperature of the corresponding coolant according to the condensation state parameter, and determine the target coolant temperature according to the first reference temperature and the second reference temperature.

[0134] Other types other than the radiant terminal device may include convective heat transfer terminals and the like.

[0135] The condensation state parameter specifically represents the state parameter of the wall condensation risk of the space where the indoor terminal device is located. The condensation state parameter may include at least one of the following parameters: the temperature data (surface temperature or coolant temperature) of the indoor terminal device, the enthalpy value data of the indoor space, the humidity data of the indoor space, the temperature data of the indoor space, and the wall temperature data of the indoor space.

[0136] The condition of the condensation risk is specifically the condition that the condensation state parameter needs to meet when there is a condensation risk in the indoor terminal device or the indoor space and the condensation risk is large. In this embodiment, the condensation state parameter includes the temperature of the indoor terminal device and the dew point temperature of the indoor space adjusted by the indoor terminal device, and the preset condensation condition includes that the temperature difference value between the temperature of the indoor terminal device and the dew point temperature is less than or equal to the preset value.

[0137] The second reference temperature is specifically the target temperature of the coolant to prevent condensation in the indoor space. Different condensation state parameters correspond to different second reference temperatures. Specifically, the second reference temperature can be calculated by substituting the condensation state parameter into the formula; the second reference temperature can also be obtained by looking up the table according to the condensation state parameter; it can also be determined the interval where the condensation state parameter is located, and the second reference temperature is determined according to the interval, and so on.

[0138] Among them, the number of the indoor terminal devices is more than one, and different indoor terminal devices are arranged in different indoor spaces. The third temperature of the corresponding refrigerant is determined according to the dew condensation state parameter of each indoor space; the second reference temperature is determined according to more than one of the third temperatures. The third temperature is specifically the target temperature of the refrigerant to prevent dew condensation in the corresponding indoor space. In this embodiment, the second reference temperature is determined according to the maximum value among more than one of the third temperatures. The maximum value among all the third temperatures is determined as the second reference temperature. In other embodiments, the average value of all the third temperatures may also be determined as the second reference temperature.

[0139] In the process of determining the target refrigerant temperature, in one implementation manner, one of the first reference temperature and the second reference temperature is determined as the target refrigerant temperature according to the magnitude relationship between the first reference temperature and the second reference temperature. In another implementation manner, the target refrigerant temperature is calculated by combining the first reference temperature and the second reference temperature. For example, the average value of the first reference temperature and the second reference temperature is used as the target refrigerant temperature; another example is that the ambient temperature of the outdoor environment where the environmental conditioning device is located can be obtained, the first weight value corresponding to the first reference temperature and the second weight value corresponding to the second reference temperature are determined according to the ambient temperature, and the target refrigerant temperature is calculated by performing weighted average calculation on the first reference temperature and the second reference temperature according to the first weight value and the second weight value.

[0140] In this embodiment, through the above method, it is possible to effectively avoid the phenomenon of dew condensation on the wall surface due to too low wall surface temperature when the terminal type is a radiant terminal, and when the terminal type is other types than the radiant terminal, sufficient cooling capacity is output to meet the comfort requirements when there is no dew condensation risk in the room. Based on this, the accuracy of the equipment temperature control is further improved, thereby improving the indoor cooling comfort and ensuring the dew condensation prevention effect of the indoor space. Among them, during the refrigeration process, when the radiant terminal or the space where it is located meets the dew condensation condition, the refrigerant temperature is corrected according to the dew condensation state parameter, which is beneficial to further improving the accuracy of the temperature control.

[0141] Further, after the step of obtaining the user demand parameter and the state parameter of the indoor terminal device, it further includes:

[0142] When the environmental conditioning device operates in the refrigeration mode, and the terminal type is a radiant terminal device and the dew condensation state parameter does not meet the preset dew condensation condition, the operation of the environmental conditioning device is maintained by controlling the target value of the current refrigerant in the refrigerant circulation system.

[0143] Here, the target value of the current secondary refrigerant can be regarded as the target secondary refrigerant temperature that the secondary refrigerant needs to reach during the current operation of the environmental conditioning equipment. In the above embodiments, when the operation duration of the environmental conditioning equipment in the current mode is less than or equal to the preset duration, the first reference temperature is the target secondary refrigerant temperature. Based on this, when the operation duration of the environmental equipment in the current mode is greater than the preset duration, the target value of the current secondary refrigerant can be the above-mentioned first reference temperature.

[0144] In this embodiment, the condensation state parameter includes the temperature of the indoor terminal equipment and the dew point temperature of the indoor space adjusted by the indoor terminal equipment. When the environmental conditioning equipment operates in the cooling mode, and the terminal type is a radiant terminal equipment and the temperature difference value between the temperature of the indoor terminal equipment and the dew point temperature is greater than the above preset value, the target value of the current secondary refrigerant temperature of the secondary refrigerant circulation system remains unchanged, and the target value of the current secondary refrigerant temperature will not be corrected by the above condensation state parameter.

[0145] In this embodiment, through the above method, while reducing the condensation risk of the radiant terminal or the space where it is located, the fluctuation of the target value of the equipment secondary refrigerant temperature can be avoided, so as to improve the operation stability of the equipment.

[0146] Further, in this embodiment, the condensation state parameter includes the first temperature difference value between the temperature of the wall surface where the indoor terminal equipment is installed and the secondary refrigerant temperature of the indoor terminal equipment, and / or the second temperature difference value between the dew point temperature of the space where the indoor terminal equipment is located and the secondary refrigerant temperature of the indoor terminal equipment. The step of determining the second reference temperature of the corresponding secondary refrigerant according to the condensation state parameter includes: determining the second reference temperature according to the first temperature difference value and / or the second temperature difference value.

[0147] In one implementation manner, a first sub-temperature corresponding to the first temperature difference value is determined, and a second sub-temperature corresponding to the second temperature difference value is determined. The second reference temperature includes the first sub-temperature and the second sub-temperature.

[0148] In another implementation manner, a temperature correction value can be determined according to the first temperature difference value and the second temperature difference value, and the second reference temperature can be obtained after correcting the preset secondary refrigerant temperature (such as the above-mentioned reference secondary refrigerant temperature) according to the temperature correction value.

[0149] In yet another implementation manner, the second reference temperature can be obtained by substituting the first temperature difference value into a formula or looking up a table.

[0150] In still another implementation manner, the second reference temperature can be obtained by substituting the second temperature difference value into a formula or looking up a table.

[0151] In this embodiment, the second reference temperature is determined by the first temperature difference value and / or the second temperature difference value. The first temperature difference value and / or the second temperature difference value can accurately reflect the condensation risk of the indoor space. Therefore, when the determined second reference temperature is applied to the determination of the target coolant temperature, it is beneficial to further reduce the condensation risk of the indoor space wall surface.

[0152] Furthermore, in this embodiment, when the second reference temperature includes a first sub-temperature and a second sub-temperature, the target coolant temperature can be determined according to the maximum value among the first reference temperature, the first sub-temperature, and the second sub-temperature. Specifically, the maximum value among the first reference temperature, the first sub-temperature, and the second sub-temperature is the target coolant temperature. Alternatively, the target coolant temperature is obtained by correcting the maximum value according to a correction value. Based on this, it is beneficial to further ensure that the temperature of the wall surface where the indoor terminal equipment is located will not be too low, and further reduce the condensation risk of the indoor space.

[0153] To better understand the determination method of the target coolant temperature mentioned in the above embodiment, a specific example is described below:

[0154] When running refrigeration, the automatic water temperature or the manual water temperature (user demand parameter) can be selected according to the demand.

[0155] When the automatic water temperature is selected, first detect the outdoor ambient temperature (outdoor ambient parameter), such as 35°C. According to the automatic water temperature of 14°C corresponding to the temperature range of 32°C to 38°C where the ambient temperature T4 is located, determine the initial target water temperature of the room TWsO = 14°C (the target coolant temperature when the operation duration of the current mode is less than or equal to the preset duration and the reference coolant temperature when the operation duration of the current mode is greater than the preset duration). After running for a period of 10 minutes, according to the difference of 5°C between the current actual room temperature of 30°C and the room temperature set value of 25°C (the current parameter value of the indoor temperature difference) and the change value of 1°C detected before and after (the parameter change value of the indoor temperature difference), determine that the water temperature correction value is -2°C. The water temperature correction value corrects the reference coolant temperature to obtain the target water temperature of the room as 12°C (the first temperature when the operation duration of the current mode is greater than the preset duration). When there are multiple terminals or multiple rooms, calculate the automatic water temperature of the room temperature respectively, so as to obtain the target water temperatures of multiple rooms (more than one first temperature), such as 12°C, 13°C, 12°C, 13.5°C. The room target water temperature TWsO = Min(12, 13, 12, 13.5) = 12°C.

[0156] When the circulation system is provided with a buffer water tank, the target water temperature of the buffer water tank TWsK (the second temperature) = TWsO (the reference coolant temperature) - dTk = 14 - 5 = 9°C. dTk is the target water temperature correction parameter for the set water temperature of the buffer water tank (the set coolant temperature of the buffer container), and the range is 0 to 10°C, preferably 5°C.

[0157] The first reference temperature is Min(TWsO, TWsK).

[0158] When the terminal type is a radiation terminal, it is determined whether the radiation terminal or the indoor space where it is located meets the condition for entering the anti-condensation function. When the condensation risk is high and the anti-condensation function needs to be entered (that is, when the condensation state parameter meets the condensation condition in the above embodiment), the dew point temperature or the radiation surface temperature is required for anti-condensation correction. When there are multiple terminals or multiple rooms, the dew point temperature anti-condensation correction temperature TWsDew (the first sub-temperature) = Ma = (12, 13, 13.5, 12, 14, 12.5) = 14°C, and the surface temperature anti-condensation correction temperature (the second sub-temperature) TWsD = Ma = (13, 12.5, 12, 13, 14.5, 14) = 14.5°C. The required final target water temperature TWs (target coolant temperature) = Ma = (Min(12, 9), 14, 14.5) = 14.5°C.

[0159] When the terminal type is a non-radiation terminal such as a fan coil unit, the final target water temperature TWs (target coolant temperature) = Min(12, 9) = 9°C.

[0160] When manual water temperature is selected, the user manually sets the target water temperature TWsM (the target temperature of the coolant set by the user, that is, the first reference temperature), such as setting 11°C. When the terminal is a radiation terminal, it is determined whether the radiation terminal or the indoor space where it is located meets the condition for entering the anti-condensation function. When the condensation risk is high and the anti-condensation function needs to be entered (that is, when the condensation state parameter meets the condensation condition in the above embodiment), at this time, the dew point temperature or the radiation surface temperature is required for anti-condensation correction. When there are multiple terminals or multiple rooms, the dew point temperature anti-condensation correction temperature TWsDew = Ma = (12, 13, 13.5, 12, 14, 12.5) = 14°C, and the surface temperature anti-condensation correction temperature TWsD = Ma = (13, 12.5, 12, 13, 14.5, 14) = 14.5°C. The required final target water temperature TWs = Ma = (11, 14, 14.5) = 14.5°C. When the terminal is a non-radiation terminal such as a fan coil unit, the final target water temperature TWs = 11°C.
