When the computer program is executed by processor 1001, it performs the functions defined in the control method of the environmental control system of the embodiments disclosed in this application.

[0101] The environmental control system provided in this application, employing the control method of the environmental control system in the following embodiments, can solve the technical problem of how to improve the energy efficiency of the system and save the overall energy cost of the system. Compared with the prior art, the beneficial effects of the environmental control system provided in this application are the same as the beneficial effects of the control method of the environmental control system provided in the following embodiments, and other technical features of this environmental control system are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0102] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control system capable of performing the above functions. The following description uses an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0103] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0104] In this embodiment, the control method of the environmental control system includes steps S10 to S20:

[0105] Step S10: Obtain the ambient temperature of the environment where the environmental conditioning system is located and the system target refrigerant temperature of the environmental conditioning system;

[0106] In this embodiment, when the preset function is enabled, the environmental control system is in a supplementary energy mode (e.g., supplementary heating mode), and step S10 is executed in the supplementary energy mode. The preset function is enabled or disabled in response to user commands. The supplementary energy mode is configured to work in conjunction with the heat pump equipment and the gas equipment to meet the temperature comfort requirements of the target space.

[0107] Ambient temperature may include indoor ambient temperature and / or outdoor ambient temperature. In this embodiment, the ambient temperature is the outdoor ambient temperature.

[0108] The system target refrigerant temperature is the pre-set target temperature that the refrigerant at the target location in the refrigerant circulation loop needs to reach. The system target refrigerant temperature can be a user-set temperature or a temperature obtained by correcting a user-set temperature. The system target refrigerant temperature represents the total heating capacity required by the environmental control system.

[0109] The target refrigerant temperature of the system can be one of the following parameters: the target refrigerant temperature in the heat exchange module (e.g., buffer tank or coupling tank), the target outlet temperature of the heat exchange module (e.g., buffer tank or coupling tank or hydraulic module), the target return temperature of the aforementioned heat exchange module (e.g., buffer tank or coupling tank or hydraulic module), the target outlet temperature of the fluid conditioning module, the target return temperature of the fluid conditioning module, etc.

[0110] Step S20: Based on the ambient temperature and the target refrigerant temperature of the system, control the environmental conditioning system to adjust the heat supply of the heat pump equipment and the gas equipment.

[0111] In one implementation, the heating capacity of the heat pump equipment is adjusted by the environmental conditioning system based on the ambient temperature and the target refrigerant temperature of the system, and the heating capacity of the gas equipment is adjusted by the environmental conditioning system based on the target refrigerant temperature of the system.

[0112] In another implementation, the heating capacity of the gas equipment is adjusted by controlling the environmental conditioning system according to the ambient temperature and the target refrigerant temperature of the system, and the heating capacity of the heat pump equipment is adjusted by controlling the environmental conditioning system according to the target refrigerant temperature of the system.

[0113] In another implementation, a first target parameter (e.g., target refrigerant temperature, heating power, air-fuel ratio, number of burners, target heat supply, or target refrigerant flow rate) representing the first heat supply of the gas equipment is determined based on the ambient temperature and the system target refrigerant temperature. A second target parameter (e.g., target refrigerant temperature, compressor target frequency, fan target speed, throttling device target opening degree, target heat supply, or target refrigerant flow rate) representing the second heat supply of the heat pump equipment is also determined based on the first target parameter. The gas equipment heats the gas equipment based on the first target parameter, and the heat pump equipment heats the gas equipment based on the second target parameter.

[0114] The methods to increase the heat output of a heat pump device may include at least one of the following: increasing the frequency of the compressor, increasing the speed of the fan corresponding to the first heat exchanger and / or the second heat exchanger, increasing the flow rate of the refrigerant that exchanges heat with the heat pump device, turning on the heat pump device, etc.

[0115] Methods to reduce the heat output of a heat pump may include at least one of the following: reducing the compressor frequency, reducing the speed of the fan corresponding to the first heat exchanger and / or the second heat exchanger, reducing the flow rate of the refrigerant that exchanges heat with the heat pump, shutting down the heat pump, etc.

[0116] Increasing the heat supply of gas equipment can be achieved by at least one of the following: increasing the opening of the gas proportional valve, increasing the air circulation volume, increasing the number of burner ignitions, increasing the flow rate of the refrigerant that exchanges heat with the gas equipment, turning on the gas equipment, etc.

[0117] Methods to reduce the heat supply of gas appliances may include at least one of the following: reducing the opening of the gas proportional valve, reducing the air circulation volume, reducing the number of burner ignitions, reducing the flow rate of the refrigerant that exchanges heat with the gas appliances, shutting off the gas appliances, etc.

[0118] After step S20, you can return to execute step S10.

[0119] This embodiment provides a control method for an environmental control system. In this method, the heat output of the heat pump equipment and gas equipment in the environmental control system is no longer selected by the user. Instead, the heat output of the heat pump equipment and gas equipment is controlled by combining the ambient temperature of the environment where the environmental control system is located and the target refrigerant temperature of the system. The ambient temperature can reflect the heating efficiency of each heat source equipment, and the target refrigerant temperature of the system can accurately reflect the current heat demand of the system. Therefore, the heat output of the heat pump equipment and gas equipment can be accurately allocated, thereby improving the energy efficiency of the system and saving the overall energy cost of the system.

[0120] In one feasible implementation, refer to Figure 5 Step S20 includes steps S21 and S22:

[0121] Step S21: Control the environmental conditioning system to adjust the heat supply of the heat pump equipment according to the ambient temperature and the target refrigerant temperature of the system;

[0122] The environmental conditioning system is controlled based on the ambient temperature and the system's target refrigerant temperature to enable or disable the heat pump. Specifically, when the heat pump is in heating mode, a first target refrigerant temperature can be determined based on the ambient temperature and the system's target refrigerant temperature. The environmental conditioning system is then used to adjust the heat pump's output based on this first target refrigerant temperature and the corresponding actual refrigerant temperature. Alternatively, a target frequency for the compressor in the heat pump can be determined based on the ambient temperature and the system's target refrigerant temperature, and the compressor can be controlled to operate at this target frequency. Alternatively, a target amount of refrigerant exchanged with the heat pump in the refrigerant circulation loop can be determined based on the ambient temperature and the system's target refrigerant temperature, and the corresponding fluid pump in the heat pump can be controlled based on this target amount of refrigerant.

[0123] The system target refrigerant temperature is the target value of the refrigerant temperature at the target location in the pre-set refrigerant circulation loop, and the first actual refrigerant temperature is the refrigerant temperature currently detected by the temperature detection module at that target location.

[0124] Step S22: Control the environmental conditioning system to adjust the heat supply of the gas equipment according to the target refrigerant temperature of the system and the first actual refrigerant temperature at the corresponding target position in the refrigerant circulation loop.

[0125] The environmental control system is controlled to increase, decrease, or maintain the heat supply of the gas equipment based on the temperature difference or relationship between the system target refrigerant temperature and the first actual refrigerant temperature; or, the environmental control system is controlled to increase, decrease, or maintain the heat supply of the gas equipment based on the system target refrigerant temperature, the first actual refrigerant temperature, and the first target refrigerant temperature corresponding to the heat pump equipment; or, the environmental control system is controlled to increase, decrease, or maintain the heat supply of the gas equipment based on the system target refrigerant temperature, the first actual refrigerant temperature, and the second actual refrigerant temperature corresponding to the heat pump equipment.

[0126] In this embodiment, the heat pump equipment is first controlled based on the ambient temperature and the system target refrigerant temperature. The remaining heat is then controlled by the gas equipment based on the system target refrigerant temperature to meet the heating needs. This approach helps to fully utilize the heat pump performance while minimizing the use of expensive gas, thereby effectively improving system energy efficiency and saving overall system energy costs.

[0127] In one feasible implementation, the step of controlling the environmental conditioning system to adjust the heat supply of the heat pump device based on the ambient temperature and the system target refrigerant temperature includes: determining a refrigerant temperature threshold based on the ambient temperature and the system target refrigerant temperature, wherein the refrigerant temperature threshold is a critical temperature that distinguishes between high and low heating efficiency of the heat pump device; and controlling the environmental conditioning system to adjust the heat supply of the heat pump device based on the ambient temperature and the characteristic relationship between the system target refrigerant temperature and the refrigerant temperature threshold.

[0128] Different ambient temperatures and different target refrigerant temperatures correspond to different refrigerant temperature thresholds. These thresholds can be positively correlated with both the ambient and target refrigerant temperatures. In one implementation, the refrigerant temperature threshold is calculated by substituting the ambient temperature and the target refrigerant temperature into a preset formula. In another implementation, the refrigerant temperature threshold can be determined based on the temperature range of both the ambient and target refrigerant temperatures.

[0129] When the system target refrigerant temperature is greater than or equal to the refrigerant temperature threshold, or the temperature difference between the system target refrigerant temperature and the refrigerant temperature threshold is greater than or equal to the temperature difference threshold, it indicates that the heat pump equipment has poor heating efficiency; when the system target refrigerant temperature is less than the refrigerant temperature threshold, or the temperature difference between the system target refrigerant temperature and the refrigerant temperature threshold is less than the temperature difference threshold, it indicates that the heat pump equipment has good heating efficiency.

[0130] The characteristic relationship may include the magnitude relationship between the system target refrigerant temperature and the refrigerant temperature threshold, or the temperature difference or ratio between the system target refrigerant temperature and the refrigerant temperature threshold, etc.

[0131] When the characteristic relationship includes magnitude, the heat pump equipment can be adjusted to adjust its heating capacity based on the temperature range of the ambient temperature and the magnitude relationship. Alternatively, the target correspondence between the ambient temperature and the target heating capacity of the heat pump equipment can be obtained based on the magnitude relationship (which may include formulas, mapping tables, etc.). Based on this target correspondence, the target heating capacity corresponding to the current ambient temperature can be determined, and the heating capacity of the heat pump equipment can be adjusted by controlling the environmental control system according to the target heating capacity.

[0132] When the characteristic relationship includes temperature difference or ratio, the target heat supply of the heat pump equipment can be calculated by substituting the ambient temperature and the temperature difference or ratio into the preset relationship formula, and the heat supply of the heat pump equipment can be adjusted by controlling the environmental conditioning system according to the target heat supply; or, the heat supply of the heat pump equipment can be adjusted by controlling the environmental conditioning system according to the temperature range of the ambient temperature and the numerical range of the temperature difference or ratio.

[0133] In this embodiment, the combination of ambient temperature and characteristic relationship can accurately reflect the efficiency of using heat pump equipment alone to adjust the refrigerant temperature in the refrigerant circulation loop to the system target refrigerant temperature. Based on this, the heat supply of the heat pump equipment can be regulated according to the ambient temperature and characteristic relationship, which is conducive to ensuring the energy efficiency of the heat pump while giving full play to the performance of the heat pump, thereby effectively improving the system energy efficiency and saving the overall energy cost of the system.

[0134] In one feasible implementation, the step of controlling the environmental conditioning system to adjust the heat supply of the heat pump device based on the characteristic relationship between the ambient temperature, the system target refrigerant temperature, and the refrigerant temperature threshold includes: controlling the environmental conditioning system to operate so that the heat pump device is in a heating state when the ambient temperature and the characteristic relationship do not meet a first condition; and controlling the environmental conditioning system to operate so that the heat pump device stops heating when the ambient temperature and the characteristic relationship meet the first condition; wherein, the first condition includes the ambient temperature being less than a preset environmental lower limit temperature and the system target refrigerant temperature being greater than or equal to the refrigerant temperature threshold, or the ambient temperature being less than the preset environmental lower limit temperature and the system target refrigerant temperature being greater than or equal to the refrigerant temperature threshold and maintained for a first duration.

[0135] The preset minimum ambient temperature is the lowest ambient temperature allowed by the preset energy efficiency of the heat pump equipment.

[0136] The first duration can be a pre-set fixed duration, or it can be determined based on the actual operating conditions of the environmental control system. For example, the first duration can be determined based on the current heat supply of the gas equipment.

[0137] The operating parameters of a heat pump when it is in heating mode can be preset fixed parameters or parameters determined according to the actual operating conditions of the environmental control system. In other words, the heat pump can have a fixed heat output or a variable heat output.

[0138] In this embodiment, the fulfillment of the first condition indicates that the heat pump equipment is inefficient under the current environment. Therefore, the heat pump equipment stops supplying heat, and all heat is provided by the gas equipment, thereby effectively improving the energy efficiency of the system.

[0139] In one feasible implementation, the step of controlling the environmental conditioning system to adjust the heat supply of the heat pump device based on the ambient temperature and the characteristic relationship between the system target refrigerant temperature and the refrigerant temperature threshold includes: determining a temperature weighting coefficient corresponding to the heat pump device based on the ambient temperature and the characteristic relationship; determining a first target refrigerant temperature of the heat pump device based on the temperature weighting coefficient and the system target refrigerant temperature; and controlling the environmental conditioning system to adjust the heat supply of the heat pump device based on the first target refrigerant temperature; wherein the temperature weighting coefficient is positively correlated with the ambient temperature, and / or the temperature weighting coefficient corresponding to the first characteristic relationship is greater than the temperature weighting coefficient corresponding to the second characteristic relationship, the first characteristic relationship being that the system target refrigerant temperature is less than the refrigerant temperature threshold, and the second characteristic relationship being that the system target refrigerant temperature is greater than or equal to the refrigerant temperature threshold.

[0140] The first heat exchange section in the refrigerant circulation loop is heat-exchange connected to the second heat exchanger in the heat pump equipment. The first target refrigerant temperature can be a target value related to the temperature of the first heat exchange section. The first target refrigerant temperature may include at least one of the following: the target outlet temperature of the first heat exchange section, the target temperature of the refrigerant in the first heat exchange section, the target return temperature of the first heat exchange section, etc.

[0141] Different ambient temperatures and different feature relationships correspond to different temperature weighting coefficients. The relationship between ambient temperature, feature relationship, and temperature weighting coefficient can be preset, including mapping relationships, formulas, algorithm models, etc. Based on this correspondence, the temperature weighting coefficient corresponding to the current ambient temperature and feature relationship can be determined.

[0142] The temperature weighting coefficient is the ratio of the first target refrigerant temperature to the system target refrigerant temperature, representing the proportion of the heat pump equipment's heat supply in the total heat supply of the environmental control system.

[0143] In this embodiment, the first target refrigerant temperature is less than or equal to the system target refrigerant temperature, and the first target refrigerant temperature can be determined based on the ambient temperature, characteristic relationships, and the system target refrigerant temperature.

[0144] In one implementation, when the characteristic relationship is a first characteristic relationship, the temperature weighting coefficient corresponding to the ambient temperature can be determined based on the first correspondence; when the characteristic relationship is a second characteristic relationship, the temperature weighting coefficient corresponding to the ambient temperature can be determined based on the second correspondence. In another implementation, a mapping relationship between different characteristic relationships, temperature ranges, and temperature weighting coefficients of the heat pump equipment can be established in advance. The target temperature range where the ambient temperature is located can be determined, and the target refrigerant temperature mapped by the current target temperature range and the characteristic relationship is used as the temperature weighting coefficient.

[0145] During the operation of the environmental control system based on the first target refrigerant temperature, the second actual refrigerant temperature of the first heat exchange section can be obtained. The target parameters are adjusted based on the second actual refrigerant temperature and the first target refrigerant temperature. The target parameters may include at least one of the following: the compressor operating frequency of the heat pump equipment, the fan corresponding to the heat exchanger in the heat pump equipment, the opening degree of the throttling device, the operating parameters of the fluid pump corresponding to the heat pump equipment, etc.

[0146] In this embodiment, higher ambient temperatures result in higher heating efficiency for the heat pump equipment, and a system target refrigerant temperature lower than the refrigerant temperature threshold also leads to high heating efficiency. A higher temperature weighting coefficient is used to determine the corresponding first target refrigerant temperature for controlling the heat pump equipment's heating supply. This means the heat pump equipment plays a larger role in the system's heating capacity, which helps ensure efficient operation of the heat pump equipment while reducing gas costs for subsequent gas-fired heating equipment. Conversely, lower ambient temperatures result in lower heating efficiency for the heat pump equipment, and a system target refrigerant temperature greater than or equal to the refrigerant temperature threshold also leads to low heating efficiency. A lower temperature weighting coefficient is used to determine the corresponding first target refrigerant temperature for controlling the heat pump equipment's heating supply. This means the heat pump equipment plays a smaller role in the system's heating capacity, which helps improve the energy efficiency of the heat pump equipment's heating process. Based on this, it is beneficial to further improve the system's energy efficiency and effectively reduce the overall energy cost of the system.

[0147] In other embodiments, the characteristic relationship may also include the temperature difference between the system target refrigerant temperature and the refrigerant temperature threshold. A temperature weighting coefficient can be determined based on the temperature difference and the ambient temperature. A relationship between the temperature difference, the ambient temperature, and the temperature weighting coefficient can be established in advance. The current temperature difference and the ambient temperature can then be substituted into the relationship to calculate the temperature weighting coefficient. The temperature weighting coefficient may be negatively correlated with the temperature difference.

[0148] In this embodiment, the step of determining the temperature weighting coefficient corresponding to the heat pump device based on the ambient temperature and the characteristic relationship includes:

[0149] If the ambient temperature and the characteristic relationship satisfy the second condition, the system target refrigerant temperature is determined as the first target refrigerant temperature; if the ambient temperature and the characteristic relationship do not satisfy the second condition, a temperature weighting coefficient corresponding to the heat pump device is determined based on the ambient temperature and the characteristic relationship, and a first target refrigerant temperature smaller than the system target refrigerant temperature is determined based on the temperature weighting coefficient and the system target refrigerant temperature; wherein, the second condition includes the ambient temperature being greater than or equal to the upper limit of the ambient temperature and the system target refrigerant temperature being less than the refrigerant temperature threshold, or the ambient temperature being greater than or equal to the upper limit of the ambient temperature and the system target refrigerant temperature being less than the refrigerant temperature threshold for a second duration.

[0150] The second condition indicates that the heat pump equipment can achieve high-efficiency heating in the current environment.

[0151] The temperature weighting coefficient can be a preset fixed value or a parameter value determined according to the actual operation of the environmental control system. The product of the temperature weighting coefficient and the target refrigerant temperature of the system can be used as the first target refrigerant temperature.

[0152] In this embodiment, when the ambient temperature and the system target refrigerant temperature meet the third condition, the first weighting coefficient is determined as the temperature weighting coefficient. The third condition includes the ambient temperature being greater than or equal to the upper limit of the ambient temperature and the system target refrigerant temperature being greater than or equal to the refrigerant temperature threshold.

[0153] When the ambient temperature and the system target refrigerant temperature meet the fourth condition, the second weighting coefficient is determined as the temperature weighting coefficient. The fourth condition includes that the ambient temperature is less than the upper limit ambient temperature and greater than or equal to the lower limit ambient temperature, and that the system target refrigerant temperature is less than the refrigerant temperature threshold.

[0154] If the ambient temperature and the system target refrigerant temperature meet the fifth condition, the third weighting coefficient is determined as the temperature weighting coefficient. The fifth condition includes that the ambient temperature is less than the upper limit ambient temperature and greater than or equal to the lower limit ambient temperature, and that the system target refrigerant temperature is greater than or equal to the refrigerant temperature threshold.

[0155] If the ambient temperature and the system target refrigerant temperature meet the sixth condition, the fourth weighting coefficient is determined as the temperature weighting coefficient. The sixth condition includes the ambient temperature being less than the ambient lower limit temperature and the system target refrigerant temperature being less than the refrigerant temperature threshold.

[0156] The first weighting coefficient, the second weighting coefficient, the third weighting coefficient, and the fourth weighting coefficient decrease sequentially.

[0157] In this embodiment, the upper limit of the ambient temperature is greater than the lower limit of the ambient temperature. Both the upper limit and the lower limit of the ambient temperature are used as critical values ​​to distinguish the heating efficiency of the heat pump equipment. When the ambient temperature is greater than or equal to the upper limit of the ambient temperature, it indicates that the heating efficiency of the heat pump equipment is high. When the ambient temperature is less than the lower limit of the ambient temperature, it indicates that the heating efficiency of the heat pump equipment is low. When the ambient temperature is greater than or equal to the lower limit of the ambient temperature but less than the upper limit of the ambient temperature, it indicates that the heating efficiency of the heat pump equipment is moderate.

[0158] In this embodiment, the temperature weighting coefficient is determined by adapting to the relationship between ambient temperature and characteristics, which helps to further improve the accuracy of the heating output control of the heat pump equipment, thereby further improving the system energy efficiency while saving the cost of system energy consumption.

[0159] In other embodiments, the temperature range in which the ambient temperature is located can be determined, and the weighting coefficient corresponding to the temperature range can be used as the temperature weighting coefficient; or, the ambient temperature can be substituted into the first formula to calculate the temperature weighting coefficient; or, when the characteristic relationship is the first characteristic relationship, the first coefficient can be used as the temperature weighting coefficient, and when the characteristic relationship is the second characteristic relationship, the second coefficient can be used as the temperature weighting coefficient, and so on.

[0160] In one feasible implementation, the first heat exchange section in the refrigerant circulation loop is connected to the heat pump device for heat exchange. The step of controlling the environmental conditioning system to adjust the heat supply of the heat pump device according to the first target refrigerant temperature includes: determining a first temperature difference value between the second actual refrigerant temperature of the first heat exchange section and the first target refrigerant temperature; when the first temperature difference value is less than or equal to a first preset temperature difference, controlling the environmental conditioning system to increase the heat supply of the heat pump device; when the first temperature difference value is greater than the first preset temperature difference, controlling the environmental conditioning system to decrease or stop the heat supply of the heat pump device.

[0161] The second actual refrigerant temperature may include at least one of the following: the actual return liquid temperature of the first heat exchange section, the actual outlet liquid temperature of the first heat exchange section, and the actual refrigerant temperature inside the first heat exchange section.

[0162] In the process of increasing the heat output of a heat pump, the compressor frequency of the heat pump can be increased and / or the fan speed of the heat pump can be increased and / or the corresponding fluid pump speed can be increased based on the first temperature difference value.

[0163] In the process of reducing the heat output of the heat pump equipment, the compressor of the heat pump equipment is controlled to reduce its frequency and / or the fan of the heat pump equipment is controlled to reduce its speed and / or the fluid pump of the heat pump equipment is controlled to reduce its speed according to the first temperature difference value.

[0164] In this embodiment, the energy efficiency of the heat pump equipment heating process is effectively improved through the above-described method.

[0165] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the step of controlling the environmental conditioning system to adjust the heating supply of the gas equipment according to the system target refrigerant temperature and the first actual refrigerant temperature at the corresponding target position in the refrigerant circulation loop includes:

[0166] The environmental control system adjusts the heat supply of the gas equipment according to the first relationship between the system target refrigerant temperature and the first actual refrigerant temperature, or the environmental control system adjusts the heat supply of the gas equipment according to the first target refrigerant temperature corresponding to the heat pump equipment, the system target refrigerant temperature, and the first actual refrigerant temperature.

[0167] During the process of adjusting the heating capacity of the gas equipment using the environmental control system based on the first relationship, when the temperature difference between the first actual refrigerant temperature and the system target refrigerant temperature is less than or equal to a second preset temperature difference, the environmental control system is controlled to start the gas equipment to provide heating or increase the heating capacity. When the temperature difference between the first actual refrigerant temperature and the system target refrigerant temperature is greater than the second preset temperature difference, the environmental control system is controlled to stop the gas equipment to provide heating or reduce the heating capacity. In this embodiment, the second preset temperature difference may be less than or equal to 0.

[0168] In this embodiment, during the process of adjusting the heating capacity of the gas equipment by controlling the environmental conditioning system based on the first target refrigerant temperature, the system target refrigerant temperature, and the first actual refrigerant temperature, the environmental conditioning system adjusts the heating capacity of the gas equipment according to a second relationship between the first actual refrigerant temperature and the system target refrigerant temperature, and a third relationship between the first target refrigerant temperature and the first actual refrigerant temperature. In this embodiment, when the second and third relationships meet preset conditions, the gas equipment is controlled to start heating or increase the heating capacity; when the second and third relationships do not meet the preset conditions, the gas equipment is controlled to stop heating or reduce the heating capacity. The preset conditions include a temperature difference between the first actual refrigerant temperature and the system target refrigerant temperature that is less than or equal to a third preset temperature difference, and a temperature difference between the first target refrigerant temperature and the first actual refrigerant temperature that is greater than or equal to a fourth preset temperature difference. Here, the third preset temperature difference is greater than or equal to the aforementioned second preset temperature difference.

[0169] When the first actual refrigerant temperature is less than or equal to the system target refrigerant temperature, the gas equipment starts heating when it is off, and increases heating capacity when it is on. When the first actual refrigerant temperature is greater than the system target refrigerant temperature, the gas equipment reduces heating capacity when its heating capacity is greater than the preset heating capacity, and stops heating when its heating capacity is less than or equal to the preset heating capacity.

[0170] During the process of reducing or increasing the heat supply of gas equipment, the operation of the environmental control system can be adjusted according to the preset adjustment parameters, or the operation of the environmental control system can be adjusted according to the adjustment parameters determined by the actual operation of the environmental control system. For example, the operation of the environmental control system can be adjusted to adjust the heat supply of the gas equipment by controlling the operation of the environmental control system based on the temperature difference between the system target refrigerant temperature and the first actual refrigerant temperature and / or the temperature difference between the system target refrigerant temperature and the first target refrigerant temperature and / or the temperature difference between the second actual refrigerant temperature and the first target refrigerant temperature.

[0171] In this embodiment, the above method enables the gas-fired equipment to accurately replenish the remaining heat required after the heat pump equipment has supplied heat, ensuring that the performance of the heat pump equipment is maximized. This allows the actual refrigerant temperature in the refrigerant circulation loop to accurately and quickly reach the system's target refrigerant temperature, improving system energy efficiency and thus enhancing the heating efficiency of the environmental control system, improving system energy efficiency, and saving energy costs. Specifically, the first relationship accurately reflects the heat required to replenish the gas-fired equipment, enabling the system to quickly and accurately reach the target refrigerant temperature. The third relationship accurately reflects the deviation between the actual refrigerant temperature in the refrigerant circulation loop under the current heat pump equipment adjustment and the target temperature achievable under heat pump equipment adjustment. When the actual refrigerant temperature of the system is far below the system's target refrigerant temperature, it indicates that the current output of the heat pump equipment cannot adjust the system's refrigerant temperature to the target temperature, resulting in a significant demand for heat replenishment from the gas-fired equipment. In this case, activating or increasing the heating capacity of the gas-fired equipment helps ensure improved system heating efficiency.

[0172] In other embodiments, during the process of controlling the environmental conditioning system to adjust the heating capacity of the gas equipment based on the first target refrigerant temperature corresponding to the heat pump device, the system target refrigerant temperature, and the first actual refrigerant temperature, the environmental conditioning system can be controlled to adjust the heating capacity of the gas equipment based on the relationship between the second actual refrigerant temperature and the first target refrigerant temperature of the first heat exchange section exchanging heat with the heat pump device, and based on the relationship between the first actual refrigerant temperature and the system target refrigerant temperature. A target temperature difference can be determined based on the relationship between the second actual refrigerant temperature and the first target refrigerant temperature, where the temperature difference between the second actual refrigerant temperature and the first target refrigerant temperature is less than or equal to... When a first preset temperature difference is established, the first temperature difference is determined as the target temperature difference. If the temperature difference between the second actual refrigerant temperature and the first target refrigerant temperature is greater than the first preset temperature difference, a second temperature difference is determined as the target temperature difference. The first temperature difference (e.g., greater than 0) is less than the second temperature difference (e.g., 0). Based on this, when the temperature difference between the system target refrigerant temperature and the first actual refrigerant temperature is greater than or equal to the target temperature difference, the environmental control system is controlled to start the gas equipment to provide heating or increase its heating capacity. When the temperature difference between the system target refrigerant temperature and the first actual refrigerant temperature is less than the target temperature difference, the environmental control system is controlled to stop the gas equipment to provide heating or reduce its heating capacity. Alternatively, the first heat exchange section in the refrigerant circulation loop is connected to the heat pump equipment for heat exchange. The environmental control system is controlled to adjust the heating capacity of the gas equipment based on the relationship between the second actual refrigerant temperature and the first target refrigerant temperature of the first heat exchange section, the relationship between the system target refrigerant temperature and the first actual refrigerant temperature, and the relationship between the first target refrigerant temperature and the first actual refrigerant temperature.

[0173] In other embodiments, during the process of adjusting the heating capacity of the gas equipment by controlling the environmental conditioning system according to the second and third relationships, the operating adjustment parameters of the environmental conditioning system corresponding to the heating capacity of the gas equipment can also be calculated based on the temperature difference between the first actual refrigerant temperature and the system target refrigerant temperature, as well as the temperature difference between the first target refrigerant temperature and the first actual refrigerant temperature, and the operation of the environmental conditioning system can be controlled according to the operating adjustment parameters.

[0174] In one feasible implementation, the first heat exchange section in the refrigerant circulation loop is connected to the heat pump device for heat exchange, and the step of controlling the environmental conditioning system to adjust the heating supply of the gas equipment according to the system target refrigerant temperature and the first actual refrigerant temperature at the corresponding target position in the refrigerant circulation loop includes:

[0175] Under the condition that the first condition is met, or under the condition that the first condition is not met and the seventh condition is met, the environmental control system adjusts the heat supply of the gas equipment according to the first relationship between the system target refrigerant temperature and the first actual refrigerant temperature; and / or

[0176] If the first condition and the seventh condition are not met, the environmental control system adjusts the heat supply of the gas equipment according to the first target refrigerant temperature corresponding to the heat pump equipment, the system target refrigerant temperature, and the first actual refrigerant temperature.

[0177] The first condition includes the ambient temperature being less than a preset lower ambient temperature and the system target refrigerant temperature being greater than or equal to a refrigerant temperature threshold, or the ambient temperature being less than a preset lower ambient temperature and the system target refrigerant temperature being greater than or equal to a refrigerant temperature threshold and maintained for a first duration. The seventh condition includes the temperature difference between the second actual refrigerant temperature of the first heat exchange section and the first target refrigerant temperature being less than or equal to a first preset temperature difference.

[0178] In this embodiment, failure to meet the first condition may include meeting one of the above-mentioned third condition, fourth condition, fifth relationship, and sixth relationship.

[0179] In this embodiment, the second preset temperature difference is greater when the first condition is met than when the first condition is not met and when the seventh condition is met. For example, the second preset temperature difference is 0 when the first condition is met, and the second preset temperature difference is less than 0 when the first condition is not met and when the seventh condition is met. The third preset temperature difference can be 0.

[0180] In this embodiment, when the heat pump equipment has low energy efficiency or when the heat pump equipment has good energy efficiency but the relevant refrigerant temperature is low under the current heating condition, the heat supply of the gas equipment is adjusted according to the first relationship. This helps to ensure that the gas equipment can fully compensate for heat and that the temperature of the refrigerant circulation loop can quickly and accurately reach the system target refrigerant temperature. When the heat pump equipment has high energy efficiency, the heat supply of the gas equipment is adjusted by combining the first target refrigerant temperature, the system target refrigerant temperature, and the first actual refrigerant temperature. This helps to effectively improve both the system heating speed and heating efficiency.

[0181] In other embodiments, if the first condition and the seventh condition are not met, the heating supply of the gas equipment can also be adjusted by controlling the environmental control system according to the first relationship described above.

[0182] In other embodiments, if the first condition is met, or if the first condition is not met and the seventh condition is met, the environmental conditioning system may be controlled to adjust the heat supply of the gas equipment based on the first target refrigerant temperature corresponding to the heat pump equipment, the system target refrigerant temperature, and the first actual refrigerant temperature.
