[0002] In addition to traditional air conditioners, environmental conditioning equipment equipped with a heat pump system and a refrigerant circulation system (such as a water circulation system, etc.) is currently used to provide the required cooling or heat for indoor environmental conditioning. The refrigerant circulation system can transfer energy to the indoor environment through the circulating refrigerant for heat exchange to adjust the environmental parameters of the indoor environment.

[0060] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0061] An embodiment of the present invention provides an environment adjustment device, specifically for adjusting the temperature of an indoor environment.

[0062] In the embodiment of the present invention, referring to Figure 1 and Figure 2 The environmental conditioning device includes a heat pump system 2, a refrigerant circulation system 3 connected to the heat pump system 2 for heat exchange, and a control device 1. The heat pump system 2 and the refrigerant circulation system 3 are both connected to the control device 1. The refrigerant circulation system is used to adjust the environmental parameters of the indoor space (such as ambient temperature and / or ambient humidity) using the energy output by the heat pump system. The heat pump system 2 is used to provide energy (such as cooling or heating) for heat exchange between the refrigerant circulation system 3 and the indoor space.

[0063] In this embodiment, the brine circulation system 3 is a water system. The heat pump system 2 is used to regulate the water supply temperature of the brine circulation system 3, which is used to regulate the indoor temperature. In this embodiment of the present invention, the water supply temperature of the brine circulation system 3 can be understood as the water outlet temperature of the heat pump system 2. In other embodiments, the brine circulation system 3 can also be a system that uses other brine to transmit energy, such as an ethanol solution.

[0064] 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.

[0065] In this embodiment, heat pump system 2 includes a refrigerant circulation loop and a heat exchange module. The refrigerant circulation loop includes a compressor 21, a first heat exchanger, a throttling device, and a second heat exchanger. The second heat exchanger is connected to the heat exchange module for heat exchange. Heat pump system 2 can operate in two modes: cooling mode and heating mode. When heat pump system 2 operates in cooling mode, the second heat exchanger is in an evaporating state, absorbing heat. When heat pump system 2 operates in heating mode, the second heat exchanger is in a condensing state, releasing heat.

[0066] The refrigerant circulation system 3 includes a refrigerant circulation loop and a terminal heat exchange device arranged in the refrigerant circulation loop. The terminal heat exchange device is arranged in the indoor space. The terminal heat exchange device may include a fan coil, a floor heating coil, a radiation plate, an air disc or a heat sink, etc. The cold or heat of the refrigerant (such as water, ethylene glycol, etc.) in the refrigerant circulation loop can be released to the indoor space where it is located at the terminal heat exchange device. Among them, there may be one or more terminal heat exchange devices, and more than one terminal heat exchange device may be distributed in different indoor spaces. The heat exchange type of the terminal heat exchange devices in different indoor spaces may be the same or different. Based on this, the cold or heat carried by the refrigerant (such as water, ethylene glycol, etc.) in the refrigerant circulation loop can be used to adjust the ambient temperature of more than one indoor space.

[0067] Specifically, the brine circulation system includes a circulating pump 31 disposed within the brine circulation loop. This circulating pump 31 is used to circulate the brine and regulate the indoor temperature using the energy output by the heat pump system. In this embodiment, the circulating pump 31 is a water pump. In other embodiments, the circulating pump 31 may alternatively be another fluid pump.

[0068] During the operation of heat pump system 2, the refrigerant in the heat exchange module of heat pump system 2 absorbs the cold or heat released by the second heat exchanger to form a refrigerant carrying cold or heat. The refrigerant carrying cold or heat flowing out of the heat exchange module can enter the refrigerant circulation loop and flow to the terminal heat exchange device to release the cold or heat to the air in the indoor space, thereby regulating the ambient temperature of the indoor space. After releasing the cold or heat, the refrigerant can re-enter the heat exchange module to exchange heat with the second heat exchanger. After the heat exchange, the refrigerant can re-enter the refrigerant circulation loop for heat exchange, and so on, thereby achieving the purpose of the environmental conditioning device regulating the temperature of the indoor space.

[0069] When the heat pump system 2 is in cooling operation, the second heat exchanger is in an evaporating state. The refrigerant in the heat exchange module absorbs the cold output by the second heat exchanger and its temperature drops to form a refrigerant carrying cold. The refrigerant carrying cold enters the refrigerant circulation loop and flows to the terminal heat exchange equipment, releasing cold to the indoor space, and the ambient temperature of the indoor space is reduced.

[0070] When the heat pump system 2 is in heating operation, the second heat exchanger is in a condensing state. The refrigerant in the heat exchange module absorbs the heat output by the second heat exchanger and its temperature rises to form a refrigerant carrying heat. The refrigerant carrying heat enters the refrigerant circulation loop and flows to the terminal heat exchange equipment, releasing heat to the indoor space, and the ambient temperature of the indoor space rises.

[0071] Furthermore, in this embodiment, the environmental conditioning device further includes a temperature detection module 4, and the control device 1 is connected to the temperature detection module 4. A portion of the pipe in the refrigerant circulation loop that is connected to the heat exchange module for heat exchange is defined as a heat exchange section. The temperature detection module 4 includes a first temperature sensor provided at the inlet of the heat exchange section and a second temperature sensor provided at the outlet of the heat exchange section. The first temperature sensor is used to detect the inlet temperature of the heat exchange section, and the second temperature sensor is used to detect the outlet temperature of the heat exchange section.

[0072] In the embodiment of the present invention, referring to Figure 2The control device 1 of the environmental conditioning device includes a processor 1001 (e.g., a CPU), a memory 1002, a timer 1003, and the like. The various components of the control device 1 are connected via a communication bus. The memory 1002 can be a high-speed RAM memory or a non-volatile memory such as a disk drive. Alternatively, the memory 1002 can be a storage device independent of the processor 1001.

[0073] 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 fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0074] like Figure 2 As shown, the memory 1002 as a storage medium may include a control program of the environment adjustment device. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the environmental conditioning device stored in the memory 1002 and execute the relevant steps of the control method of the environmental conditioning device in the following embodiments.

[0075] 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.

[0076] Reference Figure 3 , an embodiment of a control method for an environmental conditioning device of the present application is proposed. In this embodiment, the control method for the environmental conditioning device includes:

[0077] Step S10, obtaining the energy demand value of the heat pump system and / or the operating frequency of the compressor in the heat pump system;

[0078] The energy demand value is a parameter representing the current capacity requirement of a standard heat pump system. Specifically, it can be determined based on the operating parameters of the refrigerant circulation system, or a combination of the operating parameters of the refrigerant circulation system and the heat pump system, or a combination of the operating parameters of the refrigerant circulation system and the heat pump system, as well as the environmental parameters of the environment in which the heat pump system is located.

[0079] In this embodiment, the operating frequency is the frequency at which the compressor is currently operating. In other embodiments, the operating frequency may also be a frequency limit value for limiting the operation of the compressor.

[0080] Step S20, determining target operating parameters of the circulation pump according to the energy demand value and / or operating frequency;

[0081] In this embodiment, the target operating parameter is a target speed. In other embodiments, the target operating parameter may also include operating current, operating power, opening and closing duration, and / or opening degree. The target operating parameter may specifically be an optimal parameter value that effectively achieves a balance between heat exchange efficiency and energy saving efficiency of the environmental conditioning device under the current operating conditions.

[0082] Different energy demand values ​​correspond to different target operating parameters. In this embodiment, the energy demand value is positively correlated with the refrigerant flow rate corresponding to the target operating parameter. Specifically, a first corresponding relationship between the energy demand value and the target operating parameter can be established in advance. The first corresponding relationship can include a calculation formula, a mapping relationship, an operation rule, etc. The target operating parameter corresponding to the current energy demand value can be determined based on the first corresponding relationship. For example, the energy demand value can be substituted into the first formula to calculate the target operating parameter, and the numerical range of the energy demand value can also be determined. The target operating parameter is determined based on the determined numerical range.

[0083] Different operating frequencies correspond to different target operating parameters. In this embodiment, the operating frequency is positively correlated with the refrigerant flow rate corresponding to the target operating parameter. Specifically, a second corresponding relationship between the operating frequency and the target operating parameter can be established in advance. The second corresponding relationship can include calculation formulas, mapping relationships, operation rules, etc. The target operating parameter corresponding to the current operating frequency can be determined based on the second corresponding relationship. For example, the operating frequency can be substituted into the second formula to calculate the target operating parameter, and the numerical range of the operating frequency can also be determined. The target operating parameter is determined based on the determined numerical range.

[0084] Different energy demand values ​​and operating frequencies correspond to different target operating parameters. In this embodiment, both the operating frequency and the energy demand value are positively correlated with the refrigerant flow rate corresponding to the target operating parameters. Specifically, a third correspondence between the operating frequency, the energy demand value and the target operating parameter can be established in advance, and the third correspondence can include calculation formulas, mapping relationships, operation rules and other forms. Based on the third correspondence, the target operating parameters corresponding to the current operating frequency and energy demand value can be determined. For example, the operating frequency and the energy demand value can be substituted into the third formula to calculate the target operating parameters; the first numerical interval in which the operating frequency is located can also be determined, the second numerical interval in which the energy demand value is located can be determined, and the target operating parameters can be determined based on the determined first numerical interval and the second numerical interval; the first operating parameter corresponding to the energy demand value can also be determined based on the above-mentioned first correspondence, the second operating parameter corresponding to the operating frequency can be determined based on the above-mentioned second correspondence, and the target operating parameters can be determined based on the first operating parameters and the second operating parameters.

[0085] Step S30: Control the operation of the circulation pump according to the target operating parameters.

[0086] When the target operating parameter includes a target speed, the circulating pump is controlled to operate at the target speed.

[0087] When the target operating parameters include the target operating power, the circulating pump is controlled to operate at the target operating power.

[0088] When the target operating parameters include the target operating current, the circulating pump is controlled to operate at the target operating current.

[0089] A control method for environmental conditioning equipment proposed in an embodiment of the present invention is based on the environmental conditioning equipment including a heat pump system and a refrigerant circulation system, wherein the refrigerant circulation system includes a refrigerant circulation loop connected to the heat pump system for heat exchange and a circulation pump arranged in the refrigerant circulation loop. The method regulates the operation of the circulation pump according to the energy demand value of the heat pump system and / or the operating frequency of the compressor in the heat pump system. The operation of the circulation pump is no longer independent of the heat pump system, which is conducive to ensuring the accurate matching of the capacity requirements and operating status of the refrigerant circulation and the heat pump system, improving the coordination of the operation of the refrigerant circulation system and the heat pump system, and effectively avoiding excessive or too small operating parameters of the circulation pump, thereby improving the degree of balance between the heat exchange effect and the energy-saving effect of the environmental conditioning equipment.

[0090] Furthermore, 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 target operating parameters include the target speed, referring to Figure 4 , step S20 includes:

[0091] Step S21 : determining the target speed according to the energy requirement value, wherein the target speed is positively correlated with the energy requirement value.

[0092] Different energy demand values ​​correspond to different target speeds. The larger the energy demand value, the larger the target speed. Conversely, the smaller the energy demand value, the smaller the target speed.

[0093] Specifically, a correspondence between the energy demand value and the target speed can be pre-established, such as through a calculation formula, mapping relationship, or algorithmic model. If the correspondence is a preset formula, the target speed can be calculated by substituting the energy demand value into the preset formula. The quantitative relationship represented by the preset formula can have a linear or nonlinear relationship between the energy demand value and the target speed. Alternatively, if the correspondence is a mapping table, the mapping table can be queried using the energy demand value, and the speed found in the mapping table can be used as the target speed.

[0094] Furthermore, in this embodiment, a first target interval within which the energy demand value lies can be determined, with different first target intervals corresponding to different target speeds. Specifically, at least two energy demand intervals can be pre-divided, and the at least two energy demand intervals can be continuous or discontinuous. The number of the at least two energy demand intervals can be 2, 3, 4, 5, or more, and can be set based on actual conditions. Different speed values ​​are set for different energy demand intervals. Based on this, the energy demand interval within which the energy demand value lies can be determined within the at least two energy demand intervals, and the speed value associated with the determined energy demand interval is used as the target speed.

[0095] In this embodiment, when the energy requirement value is in the first energy requirement interval, the first speed is determined to be the target speed; when the energy requirement value is in the second energy requirement interval, the second speed is determined to be the target speed; when the energy requirement value is in the third energy requirement interval, the third speed is determined to be the target speed; wherein, the value within the first energy requirement interval is greater than the value within the second energy requirement interval, the value within the second energy requirement interval is greater than the value within the third energy requirement interval, the first speed is greater than the second speed, and the second speed is greater than the third speed.

[0096] The first speed, second speed and third speed here can be pre-set fixed values, or can be determined according to the operating frequency of the compressor, or can be determined according to the change value of the coil temperature of the second heat exchanger and the change value of the coil temperature of the first heat exchanger, or can be determined in combination with the operating frequency of the compressor and the indoor ambient temperature adjusted by the environmental conditioning equipment.

[0097] In this embodiment, the target speed of the circulation pump is determined according to the energy demand value, thereby ensuring that the flow rate and flow velocity of the refrigerant for heat exchange with the heat pump system can be accurately matched with the actual capacity requirements of the heat pump system. This is beneficial to avoid the heat pump system energy demand being too high and energy consumption due to the speed of the circulation pump. It can also avoid the heat pump system energy demand being too high and the speed of the circulation pump being too low, resulting in insufficient energy in the refrigerant and poor heat exchange effect between the equipment and the indoor environment, thereby further improving the balance between the heat exchange effect and the energy-saving effect of the environmental conditioning equipment.

[0098] Furthermore, in this embodiment, the heat exchange modes of the environmental conditioning devices are different. Therefore, the corresponding relationships between the energy demand value and the target rotation speed are different depending on the heat exchange modes of the environmental conditioning devices.

[0099] The heat exchange mode here is specifically divided according to the heat exchange demand (cooling demand or heating demand) of the indoor environment regulated by the environmental conditioning equipment, including heating mode or cooling mode.

[0100] A target correspondence relationship between the energy demand value and the target speed is obtained according to the heat exchange mode, and the target speed corresponding to the current energy demand value is determined based on the target correspondence relationship. In different target correspondence relationships, the same energy demand value corresponds to different target speeds.

[0101] Specifically, when the heat exchange mode is cooling mode, the target speed corresponding to the energy demand value can be determined based on the first target correspondence relationship. When the heat exchange mode is heating mode, the target speed corresponding to the energy demand value can be determined based on the second target correspondence relationship.

[0102] The energy demand intervals corresponding to the cooling mode are divided differently from those corresponding to the heating mode. The first, second, and third speeds corresponding to the cooling mode are different from those corresponding to the heating mode.

[0103] For example, when the environmental conditioning equipment is turned on and is in cooling mode, according to the interval of the energy demand value Qwn determined above, if the energy demand value Qwn is in the first energy demand interval (Qwn≥Qwncs1), the target speed of the circulation pump is determined to be the first preset speed Pumpc_Spd1; if the energy demand value Qwn is in the second energy demand interval (Qwncs2≤Qwn<Qwncs1), the target speed of the circulation pump is determined to be the second preset speed Pumpc_Spd2; if the energy demand value Qwn is in the third energy demand interval (Qwn<Qwncs2), the speed of the circulation pump is determined to be the third preset speed Pumpc_Spd3.

[0104] For another example, when the environmental conditioning equipment is turned on and is in heating mode, according to the interval of the energy demand value Qwn determined above, if the energy demand value Qwn is in the first energy demand interval (Qwn≥Qwnhs1), the target speed of the circulation pump is determined to be the first preset speed Pumph_Spd1; if the energy demand value Qwn is in the second energy demand interval (Qwnhs2≤Qwn<Qwnhs1), the target speed of the circulation pump is determined to be the second preset value Pumph_Spd2; if the energy demand value Qwn is in the third energy demand interval (Qwn<Qwnhs2), the target speed of the circulation pump is determined to be the third preset speed Pumph_Spd3.

[0105] In this embodiment, different corresponding relationships are set between energy requirements and target speeds for different heat exchange modes, thereby ensuring that both the heat exchange effect and energy saving effect of the environmental conditioning equipment can be improved under different heat exchange modes.

[0106] Furthermore, 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 target operating parameters include the target speed, referring to Figure 5 , the step S20 includes:

[0107] Step S22: determining the target speed according to the operating frequency, wherein the target speed is positively correlated with the operating frequency.

[0108] Different operating frequencies correspond to different target speeds. The greater the operating frequency, the greater the target speed. Conversely, the smaller the operating frequency, the smaller the target speed.

[0109] Specifically, a correspondence between the operating frequency and the target speed can be pre-established, such as through a calculation formula, mapping relationship, or algorithmic model. If the correspondence is a preset formula, the target speed can be calculated by substituting the operating frequency into the preset formula. The quantitative relationship represented by the preset formula can be linear or nonlinear. Alternatively, if the correspondence is a mapping table, the mapping table can be queried using the operating frequency, and the speed found in the mapping table can be used as the target speed.

[0110] Furthermore, in this embodiment, a second target interval in which the operating frequency is located can be determined, and different second target intervals correspond to different target speeds. Specifically, at least two frequency intervals can be pre-divided, and the at least two frequency intervals can be continuous intervals or discontinuous intervals. The number of the at least two frequency intervals can be 2, 3, 4, 5 or more, and can be set according to actual conditions. Different frequency intervals correspond to different speed values. Based on this, the frequency interval in which the operating frequency is located can be determined in the at least two frequency intervals, and the speed value associated with the determined frequency interval is used as the target speed.

[0111] In this embodiment, when the operating frequency is in the first frequency range, the fourth speed is determined as the target speed; when the operating frequency is in the second frequency range, the fifth speed is determined as the target speed; when the operating frequency is in the third frequency range, the sixth speed is determined as the target speed; wherein, the value within the first frequency range is greater than the value within the second frequency range, the value within the second frequency range is greater than the value within the third frequency range, the fourth speed is greater than the fifth speed, and the fifth speed is greater than the sixth speed.

[0112] The fourth speed, fifth speed and sixth speed here can be pre-set fixed values, or can be determined according to the operating frequency of the compressor, or can be determined according to the change value of the coil temperature of the second heat exchanger and the change value of the coil temperature of the first heat exchanger, or can be determined in combination with the operating frequency of the compressor and the indoor ambient temperature adjusted by the environmental conditioning equipment.

[0113] In this embodiment, the target speed of the circulation pump is determined according to the operating frequency, thereby ensuring that the flow rate and flow velocity of the refrigerant for heat exchange with the heat pump system can be accurately matched with the actual capacity requirements of the heat pump system, which is beneficial to avoid the heat pump system energy demand being too high when the circulation pump speed is too high and energy is consumed, and it can also avoid the heat pump system energy demand being too high when the circulation pump speed is too low, resulting in insufficient energy in the refrigerant and poor heat exchange effect between the equipment and the indoor environment, thereby further improving the balance between the heat exchange effect and the energy-saving effect of the environmental conditioning equipment.

[0114] Furthermore, in this embodiment, the heat exchange modes of the environmental conditioning devices are different. If the heat exchange modes of the environmental conditioning devices are different, there will be different corresponding relationships between the operating frequency and the target speed.

[0115] The heat exchange mode here is specifically divided according to the heat exchange demand (cooling demand or heating demand) of the indoor environment regulated by the environmental conditioning equipment, including heating mode or cooling mode.

[0116] A target correspondence relationship between the operating frequency and the target speed is obtained according to the heat exchange mode, and the target speed corresponding to the current operating frequency is determined based on the target correspondence relationship. Different target correspondence relationships may result in different target speeds corresponding to the same operating frequency.

[0117] Specifically, when the heat exchange mode is cooling mode, the target speed corresponding to the operating frequency can be determined based on the third target correspondence relationship. When the heat exchange mode is heating mode, the target speed corresponding to the operating frequency can be determined based on the fourth target correspondence relationship.

[0118] The frequency intervals corresponding to the cooling mode are divided differently from those corresponding to the heating mode. The fourth, fifth, and sixth speeds corresponding to the cooling mode are different from those corresponding to the heating mode.

[0119] For example, when the environmental conditioning equipment is turned on and in cooling mode, the compressor operating frequency Fr is obtained. If Fr is in the first frequency range (Fr≥Frcs1), the target speed of the circulating pump is the first preset speed Pumpc_Spd4; if Fr is in the second frequency range (Frcs2≤Fr<Frcs1), the target speed of the circulating pump is the second preset speed Pumpc_Spd5; if Fr is in the third preset range (Fr<Frcs2), the target speed of the circulating pump is the third preset speed Pumpc_Spd6.

[0120] For another example, when the environmental conditioning equipment is turned on and in heating mode, the compressor operating frequency Fr is obtained. If Fr is in the first frequency range (Fr≥Frhs1), the target speed of the circulating pump is the first preset speed Pumph_Spd4; if Fr is in the second frequency range (Frhs2≤Fr<Frhs1), the target speed of the circulating pump is the second preset speed Pumph_Spd5; if Fr is in the third frequency range (Fr<Frhs2), the target speed of the circulating pump is the third preset speed Pumph_Spd6.

[0121] In this embodiment, different corresponding relationships are set between the operating frequencies and target speeds for different heat exchange modes, which helps to ensure that the heat exchange effect and energy saving effect of the environmental conditioning equipment can be improved under different heat exchange modes.

[0122] Furthermore, 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, referring to Figure 6 , step S20 includes:

[0123] Step S201, determining a first operating parameter of the circulating pump according to the energy demand value, and determining a second operating parameter of the circulating pump according to the operating frequency;

[0124] Among them, the specific process of determining the first operating parameter of the circulating pump according to the energy demand value can be referred to the above step S21 and its detailed embodiment, which will not be repeated here; the specific process of determining the second operating parameter of the circulating pump according to the operating frequency can be referred to the above step S22 and its detailed embodiment, which will not be repeated here.

[0125] Step S202: determining the target operating parameter according to the first operating parameter and the second operating parameter.

[0126] Specifically, the parameter that satisfies the target condition between the first operating parameter and the second operating parameter can be used as the target operating parameter. In addition, the target operating parameter can be calculated by combining the first operating parameter and the second operating parameter.

[0127] For example, the maximum value of the first operating parameter and the second operating parameter can be determined as the target operating parameter, the minimum value of the first operating parameter and the second operating parameter can be determined as the target operating parameter, and the average of the first operating parameter and the second operating parameter can be determined as the target operating parameter. Alternatively, different operating parameters can correspond to different weight values, and the target operating parameter can be calculated based on the first operating parameter and the corresponding first weight value, the second operating parameter and the corresponding second weight value, wherein the first weight value and the second weight value can be pre-set fixed values, the first weight value and the second weight value can also be determined according to the type of the terminal heat exchange device, the first weight value and the second weight value can also be determined according to the temperature difference between the inlet temperature and the outlet temperature of the heat exchange part in the refrigerant circulation system and / or the temperature difference between the outlet temperature and the target temperature, etc.

[0128] In this embodiment, the target operating parameters of the circulation pump are determined by combining the first operating parameter determined by the energy demand value and the second operating parameter determined by the operating frequency. This is conducive to achieving that the operation of the circulation pump can simultaneously match the capacity demand and output capacity of the heat pump system, and further improving the degree of balance between the heat exchange effect and the energy-saving effect of the environmental conditioning equipment.

[0129] Furthermore, 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 heat exchange part in the coolant circulation loop is connected to the heat pump system for heat exchange, referring to Figure 7 , step S202 includes:

[0130] Step S2021, determining the temperature difference between the outlet temperature of the heat exchange unit and the target coolant temperature;

[0131] The target brine temperature is specifically a target temperature value that the brine temperature at the outlet of the heat exchange unit needs to reach in advance.

[0132] In this embodiment, the temperature difference is the result of subtracting the target brine temperature from the liquid outlet temperature. In other embodiments, the temperature difference may be the result of subtracting the liquid outlet temperature from the target brine temperature, or the temperature difference may be the absolute value of the difference between the liquid outlet temperature and the target brine temperature.

[0133] Step S2022: determining the target operating parameter according to the temperature difference, the first operating parameter, and the second operating parameter.

[0134] In this embodiment, the target correspondence is determined based on the temperature difference value. The target correspondence is the correspondence between the first operating parameter, the second operating parameter and the target operating parameter. Different temperature difference values ​​correspond to different target correspondences. The target operating parameters corresponding to the first operating parameter and the second operating parameter are determined according to the target correspondence.

[0135] In other embodiments, a calculation formula between the temperature difference value, the first operating parameter, the second operating parameter and the target operating parameter can be pre-set, and the target operating parameter can be calculated by substituting the temperature difference value, the first operating parameter and the second operating parameter into the calculation formula.

[0136] In this embodiment, the temperature difference value can accurately reflect the heat exchange effect after the heat exchange between the refrigerant system and the heat pump system. Based on this, the target operating parameters are determined in combination with the temperature difference value, the first operating parameter and the second operating parameter, thereby further improving the accuracy of the determined target operating parameters of the circulating pump, ensuring that the coordination of the operation of the refrigerant circulation system and the heat pump system is improved under the operation control of the circulating pump, thereby further improving the degree of balance between the heat exchange effect and the energy-saving effect of the environmental conditioning equipment.

[0137] Further, in this embodiment, step S202 includes: when the first operating parameter is consistent with the second operating parameter, determining the first operating parameter or the second operating parameter as the target operating parameter; when the first operating parameter is inconsistent with the second operating parameter, executing the step of determining the target operating parameter based on the temperature difference value, the first operating parameter and the second operating parameter.

[0138] Specifically, if the first operating parameter is equal to the second operating parameter, the first operating parameter and the second operating parameter may be considered consistent; otherwise, the two operating parameters may be considered inconsistent. Alternatively, if the deviation between the first operating parameter and the second operating parameter is less than a preset value, the first operating parameter and the second operating parameter may be considered consistent; otherwise, the two operating parameters may be considered inconsistent.

[0139] When the first and second operating parameters are consistent, controlling the circulation pump operation using either the first or second operating parameters can match the heat pump system's energy demand with its output capacity, effectively improving the balance between heat exchange and energy conservation. When the first and second operating parameters are inconsistent, this indicates a significant discrepancy between the system's energy demand and output capacity, placing significant demands on the circulation pump's control. In this case, further incorporating the temperature difference to determine the target operating parameters can improve their accuracy, further ensuring a more effective balance between heat exchange and energy conservation.

[0140] Further, in this embodiment, step S2022 includes: when the temperature difference value is within a preset temperature difference range, determining the average of the first operating parameter and the second operating parameter as the target operating parameter; when the temperature difference value is outside the preset temperature difference range, determining one of the first operating parameter and the second operating parameter as the target operating parameter based on the relationship between the temperature difference value and the preset temperature difference range.

[0141] The preset temperature difference range is specifically the target range that the temperature difference between the outlet liquid temperature and the target refrigerant temperature needs to reach when the heat exchange effect of the environmental conditioning equipment matches the energy-saving effect.

[0142] The relationship between the temperature difference value and the preset temperature difference interval here may include the size relationship between the temperature difference value and the preset temperature difference interval or the quantitative relationship (such as ratio or difference, etc.) between the temperature difference value and the critical value (maximum value and / or minimum value) of the preset temperature difference interval.

[0143] If the relationship between the temperature difference value and the preset temperature difference range is different, the parameters selected as the target operating parameters from the first operating parameter and the second operating parameter are different.

[0144] In one implementation of this embodiment, when the environmental conditioning device is in cooling mode, and when the temperature difference value is greater than the maximum value within the preset temperature difference range, the maximum parameter between the first operating parameter and the second operating parameter is determined to be the target operating parameter; when the environmental conditioning device is in cooling mode, and when the temperature difference value is less than the minimum value within the preset temperature difference range, the minimum parameter between the first operating parameter and the second operating parameter is determined to be the target operating parameter.

[0145] In another implementation of this embodiment, when the environmental conditioning device is in heating mode, and when the temperature difference value is greater than the maximum value within the preset temperature difference range, the minimum parameter between the first operating parameter and the second operating parameter is determined to be the target operating parameter; when the environmental conditioning device is in heating mode, and when the temperature difference value is less than the minimum value within the preset temperature difference range, the maximum parameter between the first operating parameter and the second operating parameter is determined to be the target operating parameter.

[0146] In this embodiment, when the temperature difference value is within the preset temperature difference range, it can be considered that the capacity demand and output capacity of the heat pump system are equivalent to the regulation demand of the circulation pump. In this case, the average of the first operating parameter and the second operating parameter is used as the target operating parameter, which is conducive to the simultaneous matching of the brine circulation with the energy demand and the output capacity, thereby further improving the effective balance between the heat exchange effect and the energy saving effect of the environmental conditioning equipment. When the temperature difference value is outside the preset temperature difference range, it can be considered that there is a high risk of deviation between the current circulation pump operation and either the output capacity or the capacity demand. The relationship between the temperature difference value and the preset temperature difference range can accurately reflect the risk of deviation. Therefore, based on this relationship, one of the first operating parameter and the second operating parameter is selected as the target operating parameter, which is conducive to the simultaneous matching of the brine circulation with the energy demand and the output capacity, thereby further improving the effective balance between the heat exchange effect and the energy saving effect of the environmental conditioning equipment.

[0147] If the temperature difference during cooling is too large or the temperature difference during heating is too small, it can be considered that the brine circulation system has a high energy demand on the heat pump system. In this case, the larger of the first and second operating parameters is used as the target operating parameter. This helps ensure that the heat exchange efficiency between the brine circulation system and the heat pump system can meet the energy demand of the heat pump system, thereby effectively ensuring the heat exchange effect of the equipment. If the temperature difference during cooling is too small or the temperature difference during heating is too large, it can be considered that the energy demand of the brine circulation system is low and the output capacity is large. In this case, the smaller of the first and second operating parameters is used as the target operating parameter. This helps reduce the efficiency between the brine circulation system and the heat pump system, so that the brine temperature is maintained near the target brine temperature, while effectively reducing the energy consumption of the circulation pump. Based on this, it is beneficial to further improve the balance between the heat exchange effect and energy saving effect of the environmental conditioning equipment.

[0148] Further, based on any of the above embodiments, the control method of the environmental conditioning device of the present application proposes another embodiment. In this embodiment, the heat exchange part in the coolant circulation loop is connected to the heat pump system for heat exchange, referring to Figure 8 , the step of obtaining the energy demand value of the heat pump system includes:

[0149] Step S11, obtaining the liquid inlet temperature of the heat exchange part and the liquid outlet temperature of the heat exchange part;

[0150] The liquid inlet temperature and liquid outlet temperature here can be detected by the above-mentioned temperature detection module.

[0151] Step S12: determining the energy requirement value according to the liquid inlet temperature, the liquid outlet temperature, the target brine temperature of the brine circulation system, and the rated capacity of the heat pump system.

[0152] Different heat exchange modes correspond to different rated capacities. In cooling mode, the rated capacity is the rated cooling capacity of the heat pump system, and in heating mode, the rated capacity is the rated heating capacity of the heat pump system.

[0153] Specifically, a correspondence between the inlet temperature, outlet temperature, target coolant temperature, and rated capacity and the energy demand value can be pre-established, and the current energy demand value can be determined based on this correspondence. In other embodiments, this correspondence can be obtained based on the current ambient temperature of the heat pump system, with different ambient temperatures corresponding to different correspondences.

[0154] In this embodiment, a first temperature difference between the liquid inlet temperature and the liquid outlet temperature is determined, and a second temperature difference between the liquid outlet temperature and the target coolant temperature is determined; and the energy requirement is determined based on the first temperature difference, the second temperature difference and the rated capacity.

[0155] In this embodiment, the first temperature difference in cooling mode is calculated by subtracting the liquid outlet temperature from the liquid inlet temperature. In heating mode, the first temperature difference is calculated by subtracting the liquid outlet temperature from the liquid inlet temperature.

[0156] The second temperature difference is a calculation result obtained by subtracting the target coolant temperature from the liquid outlet temperature.

[0157] Different first temperature difference values, different second temperature difference values, and different rated capacities correspond to different energy demand values. The corresponding relationships between the first energy demand coefficient, the second energy demand coefficient, the rated capacity, and the energy demand value vary under different heat exchange modes. Specifically, the first energy demand coefficient can be determined based on the first temperature difference value, the second energy demand coefficient can be determined based on the second temperature difference value, and the rated capacity can be corrected using the first and second energy demand coefficients to obtain the energy demand value.

[0158] In this embodiment, the above method can accurately determine the current capacity requirement of the current refrigerant circulation system for the heat pump system, improve the accuracy of the heat pump system capacity requirement representation, and further improve the accuracy of the circulation pump control.

[0159] In addition, an embodiment of the present invention further proposes a storage medium on which a control program for an environmental conditioning device is stored.
