[0002] Some environmental conditioning equipment will have a heat pump system and a refrigerant circulation system. During the operation of the heat pump system, the refrigerant circulation system can deliver the cooling or heat of the heat pump system to the indoor terminal equipment to regulate the indoor air. When the environmental conditioning equipment needs to regulate multiple indoor spaces, a fluid regulating module such as a manifold is generally set up. Different terminal equipment can be bound and connected with different fluid valves, and the binding relationship will be stored in the equipment. The refrigerant flow control of each terminal equipment is performed based on the binding relationship.

[0046] 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.

[0047] An embodiment of the present invention provides an environment conditioning device, which is specifically used to condition the air in an indoor environment.

[0048] In the embodiment of the present invention, refer to Figure 1 and Figure 2 The environment conditioning device includes a heat pump system 2, a refrigerant circulation system 3 connected to the heat pump system 2, and a control device 1, wherein the heat pump system 2 and the refrigerant circulation system 3 are both connected to the control device 1. The refrigerant circulation system 3 transmits the energy output by the heat pump system to the indoor space through the 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 or heating) for the heat exchange between the refrigerant circulation system 3 and the indoor space.

[0049] In this embodiment, the brine circulation system 3 is a water system, the heat pump system 2 is used to adjust the water supply temperature of the brine circulation system 3, and the brine circulation system 3 can adjust the indoor temperature using the indoor terminal device 31. In the embodiment of the present invention, the water supply temperature of the brine circulation system 3 can be understood as the outlet water temperature of the heat pump system 2. In other embodiments, the brine circulation system 3 can also be a system that uses a brine to transmit energy, such as an ethanol solution.

[0050] In this embodiment, the heat pump system 2 is an air source heat pump system 2. In other embodiments, the heat pump system 2 may also be a water source heat pump system, a ground source heat pump system, or a dual source heat pump system.

[0051] The refrigerant circulation system 3 includes a medium circulation loop and an indoor terminal device 31 and a heat exchange module arranged in the medium circulation loop. The heat exchange module is connected to the heat pump system 2 for heat exchange. The medium circulation loop has an inlet and an outlet. The inlet of the medium circulation loop is connected to the outlet of the heat exchange module, and the outlet of the medium circulation loop is connected to the inlet of the heat exchange module. The cold or heat of the refrigerant in the medium circulation loop can be released to the indoor space where it is located at the indoor terminal device 31.

[0052] There may be one or more indoor terminal devices 31, and more than one indoor terminal devices 31 may be distributed in different indoor spaces. The heat exchange types of the indoor terminal devices 31 in different indoor spaces may 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 ambient temperature of more than one indoor space.

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

[0054] In this embodiment, the heat pump system 2 includes a refrigerant circulation loop, which includes a compressor, a first heat exchanger, a throttling device and a second heat exchanger, and the second heat exchanger is heat-exchange connected with the heat exchange module in the refrigerant circulation system 3. The second heat exchanger and the heat exchange module can be a shell and tube heat exchanger or a plate heat exchanger.

[0055] The heat pump system 2 can have two operating modes: cooling mode and heating mode. When the heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state to absorb heat. When the heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state to release heat.

[0056] During the operation of the heat pump system 2, the water in the heat exchange module can absorb the cold or heat released by the second heat exchanger to form cold water or hot water. The medium carrying cold or heat flowing out of the heat exchange module can enter the medium circulation loop and flow to the indoor terminal device 31 to release the cold or heat to the air in the indoor space to adjust the ambient temperature of the indoor space. The medium after releasing the cold or heat can re-enter the heat exchange module to exchange heat with the second heat exchanger, and the medium after heat exchange can re-enter the medium circulation loop to exchange heat, and so on, so as to realize the adjustment of the indoor space temperature by the environmental conditioning device.

[0057] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The medium in the heat exchange module absorbs the cold output by the second heat exchanger and its temperature decreases to form a medium that carries cold. The medium that carries cold enters the medium circulation loop and flows to the indoor terminal device 31, releasing cold to the indoor space, and the ambient temperature of the indoor space decreases.

[0058] When the heat pump system 2 is in heating operation, the second heat exchanger is in a condensing state. The medium in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a heat-carrying medium. The heat-carrying medium enters the medium circulation loop and flows to the indoor terminal device 31, releasing heat to the indoor space, and the ambient temperature of the indoor space rises.

[0059] Furthermore, the refrigerant circulation system 3 also includes a fluid regulating module 32, which is connected to the control device 1. The fluid regulating module 4 can be used to adjust the distribution, flow regulation and control of the supply and return liquid in the refrigerant circulation system 3. Specifically, the heat exchange module and the indoor terminal device 31 are both connected to the fluid regulating module 32. In this embodiment, the number of indoor terminal devices 31 is at least two, and at least two indoor terminal devices 31 and the heat exchange module are connected to the fluid regulating module 32. The fluid regulating module 32 includes at least two fluid valves 321, and the fluid valves 321 are connected to the indoor terminal devices 31 in a one-to-one correspondence. The fluid valves are used to control the flow rate of the refrigerant of the corresponding indoor terminal device. In this embodiment, the fluid regulating module 4 is a manifold. In other embodiments, the fluid regulating module 32 may also be a circulating pump.

[0060] Further, in this embodiment, referring to Figure 2 The control device 1 can also be connected to the environment detection module 5, which may include an indoor temperature sensor and / or an outdoor temperature sensor. The indoor temperature sensor can detect the ambient temperature of the indoor space regulated by the environment conditioning device; the outdoor temperature sensor can detect the ambient temperature of the outdoor space where the environment conditioning device is located.

[0061] Further, in this embodiment, referring to Figure 2 The control device 1 may also be connected to a temperature sensor 6, which is disposed on the surface of the indoor terminal device to detect the surface temperature of the indoor terminal device.

[0062] In the embodiment of the present invention, refer to Figure 2 The control device 1 of the environment conditioning device includes: a processor 1001 (such as a CPU), a memory 1002, a timer 1003, etc. The various components in the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0063] Those skilled in the art will understand that Figure 2 The device structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0064] like Figure 2 As shown, the memory 1002 as a storage medium may include a control program of the environment adjustment device. Figure 2In the device shown, the processor 1001 can be used to call the control program of the environmental conditioning device stored in the memory 1002 and execute the relevant step operations of the control method of the environmental conditioning device in the following embodiments.

[0065] An embodiment of the present invention further provides a control method for an environmental conditioning device, which is applied to the above-mentioned environmental conditioning device.

[0066] Reference Figure 3 , an embodiment of a control method of an environmental conditioning device of the present application is proposed. In this embodiment, the control method of the environmental conditioning device includes:

[0067] Step S10, controlling the heat pump system to operate in a heat exchange mode and controlling the target fluid valve among the at least two fluid valves to switch the switch state, and obtaining the state parameters related to the operation of the indoor terminal device associated with the target fluid valve in the corresponding preset binding relationship;

[0068] The heat exchange mode includes a cooling mode or a heating mode. The heating mode corresponds to a target state of the indoor terminal device being a heating state, and the cooling mode corresponds to a target state of the indoor terminal device being a cooling state.

[0069] The target fluid valve may be a fluid valve for which the preset binding relationship corresponding to any one of the at least two fluid valves is unknown to be correct.

[0070] Different fluid valves may correspond to different preset binding relationships, and the preset binding relationship includes an association relationship between the fluid valve and an associated indoor terminal device.

[0071] The switching state of the target fluid valve includes: when the target fluid valve is in a closed state, the target fluid valve is controlled to perform an opening action; when the target fluid valve is in an open state, the target fluid valve is controlled to perform a closing action.

[0072] The state parameters may characterize the heat exchange state of the indoor terminal device. Here, the state parameters may include the temperature monitoring parameters of the indoor terminal device itself (such as surface temperature value, surface temperature change value, refrigerant temperature value, refrigerant temperature change value, etc.) and / or the environmental parameters of the environment (such as ambient temperature value, ambient temperature change value, etc.).

[0073] In this embodiment, the switch state of the target fluid valve after switching the switch state is different from the switch state of the other fluid valves other than the target fluid valve among the at least two fluid valves. Specifically, the target fluid valve is in the open state after performing the opening action, and the other fluid valves are in the closed state. Alternatively, the target fluid valve is in the closed state after performing the closing action, and the other fluid valves are in the open state.

[0074] In this embodiment, when the target fluid valve switches the switch state and obtains the state parameter, the switch states of other fluid valves other than the target fluid valve remain unchanged.

[0075] Step S20: determining whether the preset binding relationship is correct according to the state parameter.

[0076] Specifically, a target parameter range that the state parameter needs to reach when the preset binding relationship is correct can be preset. When the state parameter is within the target parameter range, it can be determined that the preset binding relationship is correct; when the state parameter is outside the target parameter range, it can be determined that the preset binding relationship is correct.

[0077] A control method for an environmental conditioning device is proposed in an embodiment of the present invention. The method controls the switching state of a target fluid valve during the operation of a heat exchange mode of a heat pump system and obtains state parameters related to the operation of an indoor terminal device associated with the target fluid valve in a preset binding relationship. Whether the preset binding relationship is correct is determined according to the state parameters of the operation of the indoor terminal device. Based on this, the verification of the preset binding relationship no longer needs to be performed manually, but the verification of whether the preset binding relationship is accurate can be completed based on the detection of state parameters and data analysis by a machine, thereby reducing the inefficiency and misjudgment problems caused by manual verification, and effectively improving the verification efficiency and verification accuracy of the binding relationship between the fluid valve and the indoor terminal device.

[0078] Further, based on the above embodiment, another embodiment of the control method of the environmental conditioning device of the present application is proposed. In this embodiment, the state parameter includes a first temperature change value of the indoor terminal device and / or a second temperature change value of the indoor environment where the indoor terminal device is located, and the step of determining whether the preset binding relationship is correct according to the state parameter includes: determining whether the preset binding relationship is correct according to the first temperature change value and / or the second temperature change value.

[0079] In this embodiment, the first temperature change value and the second temperature change value are both determined according to the temperature detected within a preset time period after the target fluid valve switches the switch state.

[0080] The first temperature of the indoor terminal device at the start time of the fluid valve switching switch state is obtained, and the second temperature of the indoor terminal device at the end time after the fluid valve switching switch state is obtained, wherein the interval between the start time and the end time is set to a time length, and the first temperature change value here is determined according to the first temperature and the second temperature. When the heat pump system operates in cooling mode, the difference between the first temperature and the second temperature can be determined as the first temperature change value; when the heat pump system operates in heating mode, the difference between the second temperature and the first temperature can be determined as the first temperature change value.

[0081] The first ambient temperature of the environment where the indoor terminal device is located at the start time of the fluid valve switching switch state is obtained, and the second ambient temperature of the environment where the indoor terminal device is located at the end time of the fluid valve switching switch state is obtained, wherein the interval between the start time and the end time is set to a time length, and the second temperature change value here is determined according to the first ambient temperature and the second ambient temperature. When the heat pump system operates in cooling mode, the difference between the first ambient temperature and the second ambient temperature can be determined as the second temperature change value; when the heat pump system operates in heating mode, the difference between the second ambient temperature and the first ambient temperature can be determined as the second temperature change value.

[0082] In other embodiments, the first temperature change value and the second temperature change value may also be determined based on the temperatures detected before and after the target fluid valve switches the switch state. For example, the first temperature change value is determined based on the third temperature and the fourth temperature of the indoor terminal device detected before and after the target fluid valve switches the switch state; the second temperature change value is determined based on the third ambient temperature and the fourth ambient temperature of the environment where the indoor terminal device is located detected before and after the target fluid valve switches the switch state.

[0083] Different first temperature change values ​​and / or different second temperature change values ​​correspond to different determination results of whether the preset binding relationships are correct. The correspondence between the first temperature change value, the second temperature change value and the determination result can be preset, and the correspondence can include a calculation relationship or a mapping table. Based on the correspondence, the preset binding relationship corresponding to the first temperature change value and / or different second temperature change values ​​can be determined. Among them, the correspondence here can be determined according to the heat exchange mode currently running in the heat pump system and the switching action performed by the target fluid valve.

[0084] In one implementation, whether the preset binding relationship is correct may be determined based on whether the first temperature change value reaches a first preset parameter range.

[0085] In another implementation, whether the preset binding relationship is correct may be determined based on whether the second temperature change value reaches a second preset parameter range.

[0086] In another implementation, whether the preset binding relationship is correct is determined based on whether the first temperature change value reaches the first preset parameter interval and whether the second temperature change value reaches the second preset parameter interval. Alternatively, whether the preset binding relationship is correct is determined based on the quantitative relationship or size relationship between the first temperature change value and the second temperature change value.

[0087] In this embodiment, when the preset binding relationship is correct, the switching action of the target fluid valve will cause the temperature of the indoor terminal device itself and / or the ambient temperature of the environment in which the indoor terminal device is located to change significantly. Therefore, the first temperature change value and / or the second temperature change value can be used to accurately distinguish whether the preset binding relationship corresponding to the target fluid valve is correct, thereby improving the verification efficiency while improving the accuracy of the verification results.

[0088] Further, in this embodiment, the step of determining whether the preset binding relationship is correct based on the first temperature change value includes: when the first temperature change value is greater than the first preset temperature change value, determining that the preset binding relationship is correct; when the first temperature change value is less than or equal to the first preset temperature change value, determining that the preset binding relationship is incorrect.

[0089] The first preset temperature change value may be a preset fixed value, or a value determined according to the actual operation of the environmental conditioning device. For example, the first preset temperature change value may be determined according to the outdoor ambient temperature and the number of fluid valves currently opened.

[0090] When the heat pump system operates in cooling mode, the target fluid valve performs an opening action in the closed state. When the preset binding relationship is correct, the refrigerant carrying the coldness of the heat pump system can flow into the associated indoor terminal equipment, causing the temperature of the indoor terminal equipment to drop significantly. At this time, the first temperature change value is greater than the first preset temperature change value; when the preset binding relationship is incorrect, the amount of refrigerant flowing into the indoor terminal equipment will not change due to the change in the switching state of the target fluid valve, and the temperature of the indoor terminal equipment remains almost unchanged. At this time, the first temperature change value is less than or equal to the first preset temperature change value.

[0091] When the heat pump system operates in cooling mode, the target fluid valve performs a closing action in the open state. When the preset binding relationship is correct, the refrigerant carrying the coldness of the heat pump system stops flowing into the associated indoor terminal equipment, causing the temperature of the indoor terminal equipment to rise significantly. At this time, the first temperature change value is greater than the first preset temperature change value; when the preset binding relationship is wrong, the amount of refrigerant flowing into the indoor terminal equipment will not change due to the change in the switching state of the target fluid valve, and the temperature of the indoor terminal equipment remains almost unchanged. At this time, the first temperature change value is less than or equal to the first preset temperature change value.

[0092] When the heat pump system operates in the heating mode, the target fluid valve performs an opening action in the closed state. When the preset binding relationship is correct, the coolant carrying the heat of the heat pump system can flow into the associated indoor terminal device, causing the temperature of the indoor terminal device to rise significantly. At this time, the first temperature change value is greater than the first preset temperature change value. When the preset binding relationship is incorrect, the amount of coolant flowing into the indoor terminal device will not change due to the change in the on-off state of the target fluid valve, and the temperature of the indoor terminal device remains almost unchanged. At this time, the first temperature change value is less than or equal to the first preset temperature change value.

[0093] When the heat pump system operates in the heating mode, the target fluid valve performs a closing action in the open state. When the preset binding relationship is correct, the coolant carrying the heat of the heat pump system stops flowing into the associated indoor terminal device, causing the temperature of the indoor terminal device to drop significantly. At this time, the first temperature change value is greater than the first preset temperature change value. When the preset binding relationship is incorrect, the amount of coolant flowing into the indoor terminal device will not change due to the change in the on-off state of the target fluid valve, and the temperature of the indoor terminal device remains almost unchanged. At this time, the first temperature change value is less than or equal to the first preset temperature change value.

[0094] In this embodiment, the accuracy of the preset binding relationship is effectively improved by accurately determining whether the preset binding relationship is correct through the relationship between the temperature change of the indoor terminal device when the on-off state of the target fluid valve is switched and the first preset temperature change value.

[0095] Further, in this embodiment, the step of determining whether the preset binding relationship is correct according to the second temperature change value includes: when the second temperature change value is greater than the second preset temperature change value, it is determined that the preset binding relationship is correct; when the second temperature change value is less than or equal to the second preset temperature change value, it is determined that the preset binding relationship is incorrect.

[0096] The second preset temperature change value can be a fixed value set in advance or a value determined according to the actual operating conditions of the environmental control device. For example, the second preset temperature change value here can be determined according to the outdoor environmental temperature and the number of currently opened fluid valves.

[0097] When the heat pump system operates in the cooling mode, the target fluid valve performs an opening action in the closed state. When the preset binding relationship is correct, the coolant carrying the cold of the heat pump system can flow into the associated indoor terminal device, and the indoor terminal device can release cold to the indoor space where it is located, causing the temperature of the indoor space to drop significantly. At this time, the second temperature change value is greater than the second preset temperature change value. When the preset binding relationship is incorrect, the amount of coolant flowing into the indoor terminal device will not change due to the change in the on-off state of the target fluid valve, and the temperature of the indoor space where it is located remains almost unchanged. At this time, the second temperature change value is less than or equal to the second preset temperature change value.

[0098] When the heat pump system operates in cooling mode, the target fluid valve performs a closing action in the open state. When the preset binding relationship is correct, the refrigerant carrying the cold of the heat pump system stops flowing into the associated indoor terminal device, and the indoor terminal device can stop releasing cold to the indoor space where it is located, causing the temperature of the indoor space to rise significantly. At this time, the second temperature change value is greater than the second preset temperature change value; when the preset binding relationship is wrong, the amount of refrigerant flowing into the indoor terminal device will not change due to the change in the switching state of the target fluid valve, and the temperature of the indoor space where it is located remains almost unchanged. At this time, the second temperature change value is less than or equal to the second preset temperature change value.

[0099] When the heat pump system operates in heating mode, the target fluid valve performs an opening action in the closed state. When the preset binding relationship is correct, the refrigerant carrying the heat of the heat pump system can flow into the associated indoor terminal device, and the indoor terminal device can release heat to the indoor space where it is located, causing the temperature of the indoor space to rise significantly. At this time, the second temperature change value is greater than the second preset temperature change value; when the preset binding relationship is wrong, the amount of refrigerant flowing into the indoor terminal device will not change due to the change in the switching state of the target fluid valve, then the temperature of the indoor space where it is located remains almost unchanged, and the second temperature change value is less than or equal to the second preset temperature change value.

[0100] When the heat pump system operates in heating mode, the target fluid valve performs a closing action in the open state. When the preset binding relationship is correct, the refrigerant carrying the heat of the heat pump system stops flowing into the associated indoor terminal device, and the indoor terminal device can stop releasing heat to the indoor space where it is located, causing the temperature of the indoor space to drop significantly. At this time, the second temperature change value is greater than the second preset temperature change value; when the preset binding relationship is wrong, the amount of refrigerant flowing into the indoor terminal device will not change due to the change in the switching state of the target fluid valve, then the temperature of the indoor space where it is located remains almost unchanged, and the second temperature change value is less than or equal to the second preset temperature change value.

[0101] In this embodiment, whether the preset binding relationship is correct is accurately determined by comparing the temperature change of the indoor space where the indoor terminal device is located when the target fluid valve switch state is switched with the second preset temperature change value, thereby effectively improving the accuracy of the verification efficiency of the preset binding relationship.

[0102] Further, in the present embodiment, the step of determining whether the preset binding relationship is correct according to the first temperature change value and / or the second temperature change value includes: when the first temperature change value is greater than the first preset temperature change value, determining that the preset binding relationship is correct; when the first temperature change value is less than or equal to the first preset temperature change value, determining whether the preset binding relationship is correct according to the second temperature change value.

[0103] In this embodiment, the first temperature change value is less than or equal to the first preset temperature change value, indicating that the preset binding relationship has an error risk. At this time, whether the preset binding relationship is correct is further determined based on the second temperature change value. This can avoid incorrect verification results caused by temperature sensor failure on the indoor terminal device or unclear temperature change when the temperature is close to the ambient temperature, thereby further improving the accuracy of the preset binding relationship verification.

[0104] Further, in the present embodiment, the step of determining whether the preset binding relationship is correct according to the first temperature change value and / or the second temperature change value includes: when a temperature sensor is not installed on the indoor terminal device, determining whether the preset binding relationship is correct according to the second temperature change value; when a temperature sensor is installed on the indoor terminal device, determining whether the preset binding relationship is correct according to the first temperature change value, or determining whether the preset binding relationship is correct according to the first temperature change value and the second temperature change value.

[0105] In this embodiment, when a temperature sensor is installed on the indoor terminal device, when the first temperature change value is greater than the first preset temperature change value, the preset binding relationship is determined to be correct; when the first temperature change value is less than or equal to the first preset temperature change value, and the second temperature change value is greater than the second preset temperature change value, the preset binding relationship is determined to be correct; when the first temperature change value is less than or equal to the first preset temperature change value, and the second temperature change value is less than or equal to the second preset temperature change value, the preset binding relationship is determined to be incorrect.

[0106] 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, different fluid valves correspond to different preset binding relationships, referring to Figure 4 , after the step of determining whether the preset binding relationship is correct according to the state parameter, the method further includes:

[0107] Step S30, when the preset binding relationship is correct, determining the fluid valve that meets the preset conditions among the at least two fluid valves as a new target fluid valve;

[0108] After step S30, return to the step of controlling the heat pump system to operate in the heat exchange mode and controlling the switch state of the target fluid valve among the at least two fluid valves, and obtaining the state parameters related to the operation of the indoor terminal device associated with the target fluid valve in the corresponding preset binding relationship, until there is no fluid valve that meets the preset conditions; wherein the preset conditions include whether the corresponding preset binding relationship is unknown and whether it is correct.

[0109] Based on this, it is possible to effectively verify whether the preset binding relationships corresponding to all fluid valves in the environmental conditioning device are accurate, thereby effectively improving the efficiency and accuracy of verifying all preset binding relationships in the environmental conditioning device.

[0110] In other embodiments, when it is determined that the preset binding relationship is wrong, the fluid valve that meets the preset conditions among the at least two fluid valves is determined to be the new target fluid valve, and the steps of controlling the heat pump system to operate in the heat exchange mode and controlling the switch state of the target fluid valve among the at least two fluid valves are returned to execute, and obtaining the state parameters related to the operation of the indoor terminal device associated with the target fluid valve in the corresponding preset binding relationship are obtained until there is no fluid valve that meets the preset conditions.

[0111] Furthermore, in this embodiment, the switching switch state includes switching from a closed state to an open state, and before the step of determining that the fluid valve among the at least two fluid valves that meets the preset conditions is the new target fluid valve, it also includes: when the preset binding relationship is correct, controlling the current target fluid valve to perform a closing action.

[0112] In this embodiment, when it is unknown whether the preset binding relationships corresponding to all fluid valves are correct, all fluid valves can be in a closed state, and each fluid valve is taken as a target fluid valve in turn, and one of the fluid valves is opened to perform a corresponding state parameter detection. After the verification result of the corresponding preset binding relationship is obtained to be correct, the currently opened fluid valve is closed and then the next fluid valve is opened to verify its preset binding relationship.

[0113] In this embodiment, when verifying the preset binding relationship of all fluid valves, mutual influence can be effectively avoided to effectively improve the accuracy of the verification result.

[0114] Furthermore, in this embodiment, after the step of determining whether the preset binding relationship is correct according to the state parameters, it also includes: when the preset binding relationships corresponding to all fluid valves are correct, when the preset binding relationships corresponding to all fluid valves are correct, controlling the operation of the environmental conditioning device according to the target heat exchange demand of the indoor space and the preset binding relationship.

[0115] The target heat exchange demand includes the target heat exchange mode and the corresponding set temperature. The target heat exchange mode here may be the same as or different from the heat exchange mode in which the heat pump system operates during the preset binding relationship verification process. The target heat exchange mode is determined based on the actual heat exchange demand of the user, and specifically, it can be determined based on user instructions. The set temperature is specifically the target temperature that the indoor space environment needs to achieve under the target heat exchange mode.

[0116] Different indoor spaces can correspond to different target heat exchange requirements.

[0117] For example, when the target heat exchange mode of the target indoor space is the cooling mode, the heat pump system can be controlled to operate in the cooling mode and the control valve bound to the indoor terminal device in the target indoor space can be opened according to the preset binding relationship. When the target indoor space does not need to turn on the cooling mode or heating mode, the heat pump system can be controlled to operate in the cooling mode and the control valve bound to the indoor terminal device in the target indoor space can be closed according to the preset binding relationship.

[0118] In this embodiment, when all preset binding relationships are correct, the operation of the environmental conditioning equipment is controlled according to the preset binding relationships and the target heat exchange requirements of the indoor space, thereby ensuring that the heat exchange requirements of each indoor space can be accurately met, thereby effectively improving the comfort of users in each indoor space.

[0119] Further, based on any of the above embodiments, another embodiment of the control method of the environmental conditioning device of the present application is proposed. Figure 5 , after the step of determining whether the preset binding relationship is correct according to the state parameter, the method further includes:

[0120] Step S40, when the preset binding relationship is wrong, output corresponding prompt information;

[0121] The prompt information may include at least one of the following forms: text, sound, light, image, etc.

[0122] The prompt information may include identification information of the target fluid valve and characterization information of an error in the preset binding relationship.

[0123] In this embodiment, the environment adjustment device may further include an interaction module, and prompt information is displayed on an interaction interface of the interaction module.

[0124] Step S50, when correction information corresponding to the preset binding relationship is received, correcting the preset binding relationship according to the correction information;

[0125] After step S50, return to the step of controlling the heat pump system to operate in the heat exchange mode and controlling the switch state of the target fluid valve among the at least two fluid valves, and obtaining the state parameters related to the operation of the indoor terminal device associated with the target fluid valve in the corresponding preset binding relationship.

[0126] The correction information may specifically include the indoor terminal device associated with the corrected target fluid valve. The correction information is specifically input by the user after receiving the prompt information.

[0127] The preset binding relationship corrected here includes the preset binding relationship associated with the current target fluid valve.

[0128] In this embodiment, after a preset binding relationship error is discovered, a prompt message is promptly output to promptly correct the preset binding relationship, rather than correcting it after all preset binding relationships have been verified. This is beneficial for ensuring the timeliness of the correction while improving the subsequent verification efficiency of other preset binding relationships.

[0129] In other embodiments, after obtaining verification results of whether all preset binding relationships are correct, prompt information may be output according to all verification results.

[0130] Further, based on any of the above embodiments, in this embodiment, the step of controlling the heat pump system to operate in a heat exchange mode includes: obtaining the ambient temperature of the environment where the environment conditioning device is located; when the ambient temperature is greater than or equal to a preset ambient temperature, controlling the heat pump system to operate in a cooling mode; when the ambient temperature is less than the preset ambient temperature, controlling the heat pump system to operate in a heating mode. Based on this, it is beneficial to improve the comfort of indoor users during the preset binding relationship verification process.

[0131] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program of an environmental conditioning device is stored. When the control program of the environmental conditioning device is executed by a processor, the relevant steps of any embodiment of the control method of the environmental conditioning device as described above are implemented.
