Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0089] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0090] In this embodiment, the control method of the environmental control system includes steps S10 to S30:

[0091] Step S10: Control both the first terminal device and the second terminal device to run in heating mode and obtain indoor temperature status parameters;

[0092] During the heating mode operation of the first terminal device, the gas equipment heats the flowing refrigerant by burning gas. The heated refrigerant flows into the first terminal device in the corresponding indoor space after the corresponding sub-regulation module in the fluid regulation module is opened. After the heated refrigerant is conducted to the first terminal device in the indoor space, it releases heat to heat the air in the indoor space where the first terminal device is located. Then, after the heated refrigerant releases heat, it returns to the gas equipment through a heat exchange device for circulation heating. Through continuous circulation heating, the indoor space where the first terminal device is located achieves the heating effect.

[0093] When the second terminal device operates in heating mode, the refrigerant discharged from the compressor flows sequentially through the second heat exchanger, the second terminal device, the throttling device, and the first heat exchanger before returning to the compressor. Both the second heat exchanger and the second terminal device are in a heat-releasing state, while the first heat exchanger is in a heat-absorbing state. During this process, the refrigerant in the refrigerant circulation system circulates. As the refrigerant flows through the heat exchange module, it absorbs the heat released by the second heat exchanger and then flows to the second terminal device. When the second terminal device in the indoor space with heating needs turns on, it releases heat into the space it is in, thereby achieving a heating effect.

[0094] In this embodiment, under heating mode, the second terminal device and the first terminal device have different characteristics in their impact on the temperature of the indoor space, which are mainly reflected in the uniformity of space temperature and the heating effect.

[0095] For secondary terminal units, because their air outlets are typically located higher in the room, hot air primarily affects the upper levels. This design can, in some cases, lead to indoor temperature stratification, where the upper levels are warmer than the areas closer to the floor. This stratification can reduce indoor comfort, as the body primarily feels the heat from its lower body. However, the heating performance of secondary terminal units is generally quite stable and can meet the needs of most households. Especially when outdoor temperatures are not too low, the heating effect of secondary terminal units can be quite ideal.

[0096] In contrast, the heating method of primary terminal devices is more uniform. These devices work by laying pipes under the floor, conducting heat generated by hot water or electric heating elements to the ground, and then distributing the heat evenly throughout the room via radiant floor heating. This method results in a more uniform indoor temperature distribution, preventing noticeable temperature stratification. Furthermore, the heating effect of primary terminal devices is more comfortable because the heat is transferred from bottom to top, aligning with human physiological needs.

[0097] In practical use, since the first terminal device heats up more slowly than the second terminal device, both can be turned on simultaneously for heating to achieve rapid indoor temperature increases. This means both the first and second terminal devices can be controlled to operate in heating mode simultaneously, ensuring the indoor temperature meets comfort requirements. From the perspective of temperature uniformity and heating effect, the first terminal device has a greater advantage than the second. Therefore, when both devices are operating simultaneously, priority should be given to controlling the second terminal device when the temperature requirement is met. For example, the second terminal device can be turned off or its fan speed lowered, while the first terminal device remains operational to maintain a uniform indoor temperature. The first terminal device can make the indoor temperature distribution more even, improving the comfort of occupants.

[0098] In this embodiment, the heat pump system can be turned on or off during the heating process of the first terminal device. The heat pump system can be turned on in response to a user command, or when the operating status of the heat pump system and / or environmental parameters and / or the refrigerant in the refrigerant circulation loop meet the heat replenishment conditions, etc.

[0099] In this embodiment, the heating mode can be controlled to be operated by both the second terminal device and the first terminal device based on the comparison result between the area temperature and the comfort temperature threshold of the area where the first terminal device is installed and / or the comparison result between the indoor temperature and the comfort temperature threshold of the area where the second terminal device is located.

[0100] In this embodiment, indoor temperature state parameters are used to describe various parameters of indoor temperature and to characterize the characteristics and state of indoor temperature, including but not limited to: minimum indoor temperature, maximum indoor temperature, average indoor temperature, indoor temperature distribution, indoor temperature change rate, indoor temperature stability, etc.

[0101] In this embodiment, indoor temperature status parameters can be obtained through a temperature sensor, or by connecting to an indoor temperature sensor or a smart thermostat. Users can view real-time indoor temperature status parameters through a smartphone application or other interface. By obtaining indoor temperature status parameters, users can better understand the indoor environment and take appropriate measures to adjust the temperature, thereby improving comfort and energy efficiency.

[0102] Step S20: Control the heat supply of the first terminal device according to the indoor temperature status parameters and the set temperature of the first terminal device, and control the heat supply of the second terminal device according to the indoor temperature status parameters and the set temperature of the second terminal device.

[0103] The set temperature of the first terminal device is specifically the target temperature that the area where the first terminal device is installed needs to achieve. The set temperature of the first terminal device can be a preset fixed temperature, such as a maximum temperature. In this embodiment, the maximum temperature ranges from [25~35]℃. Alternatively, the set temperature of the first terminal device can also be a temperature determined based on the actual operating conditions of the environmental control system. For example, the set temperature of the first terminal device can be determined based on the running time of the first terminal device in the current heating mode and / or the ratio of the number of first terminal devices in the current heating mode to the total number of first terminal devices.

[0104] The set temperature of the second-terminal device is specifically the target value of the indoor temperature detected in the area where the second-terminal device is located. The set temperature of the second-terminal device can be a pre-set fixed temperature, such as the maximum temperature, or it can be determined based on the actual operation of the environmental control system. For example, it can be determined based on the running time of the second-terminal device in the current heating mode and / or the ratio of the number of second-terminal devices in the current heating mode to the total number of terminal devices. Alternatively, the set temperature can be determined based on the size of the indoor space and / or the number of people. If the room is large or there are many people, a lower set temperature may be needed to achieve better cooling or heating effects. Or, the set temperature can be determined based on the temperature difference between the indoor temperature and the current outdoor temperature; the larger the temperature difference, the better the cooling effect. Excessive temperature differences may cause discomfort; determining the set temperature based on the indoor-outdoor temperature difference can improve indoor comfort. Finally, the set temperature of the second-terminal device can be determined based on energy efficiency and energy saving.

[0105] In this embodiment, the heat supply of the first terminal device can be controlled based on the comparison result between the indoor temperature status parameter and the set temperature of the first terminal device, and the heat supply of the second terminal device can be controlled based on the comparison result between the indoor temperature status parameter and the set temperature of the second terminal device.

[0106] This embodiment provides a control method for an environmental control system. By setting the set temperature of a first terminal device and the set temperature of a second terminal device, the first terminal device is controlled using the set temperature of the first terminal device and the indoor temperature status parameters, and the second terminal device is controlled using the set temperature of the second terminal device and the indoor temperature status parameters. By controlling the first terminal device and the second terminal device respectively using the set temperature of the first terminal device and the set temperature of the second terminal device, the heating output of the first terminal device and the second terminal device are not mutually restrictive, thereby improving the overall heating effect of the environmental control system.

[0107] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment can be referred to the above description and will not be repeated hereafter. Based on this, the indoor temperature status parameter includes the area temperature of the first terminal device installation area and the indoor temperature detected in the area where the second terminal device is located. Step S20 includes steps S21~S22:

[0108] Step S21: Control the heat supply of the first terminal device according to the temperature of the area and the set temperature of the first terminal device;

[0109] The regional temperature of the first-terminal equipment installation area includes, but is not limited to: the maximum temperature of the installation area, the minimum temperature of the installation area, the average temperature of the installation area, the rate of change of the regional temperature of the installation area, the temperature distribution of the installation area, and the temperature stability of the installation area. Among these, the rate of change of regional temperature refers to the amount of temperature change in the installation area per unit time; temperature distribution refers to the temperature distribution at different locations within the installation area; and temperature stability refers to the degree of temperature fluctuation in the installation area, reflecting the stability of the regional temperature. These temperature parameters can be measured and monitored using sensors, temperature measuring instruments, and other equipment to enable real-time monitoring and analysis of the temperature status of the first-terminal equipment installation area.

[0110] The installation area of ​​the aforementioned first terminal device includes the bottom of the indoor space, the top of the indoor space, or other locations within the indoor space.

[0111] In this embodiment, the heat supply of the first terminal device can be controlled based on the comparison result between the regional temperature and the set temperature of the first terminal device.

[0112] Step S22: Control the heat supply of the second terminal device according to the indoor temperature and the set temperature of the second terminal device.

[0113] The indoor temperature detected in the area where the second terminal device is located includes, but is not limited to: the maximum temperature, minimum temperature, average temperature, temperature change rate, temperature distribution, temperature stability, etc., detected in the area where the second terminal device is located.

[0114] The indoor temperature can be obtained from the temperature sensor installed on the second terminal device. Alternatively, the indoor temperature can be obtained from the sum of the area temperature of the area where the first terminal device is installed and the sensor-compensated temperature. The sensor-compensated temperature has a range of -20 to 20°C, preferably -3°C. This allows the indoor temperature to be obtained from the area temperature and the sensor-compensated temperature. Only one temperature sensor is needed to obtain both the area temperature and the indoor temperature, reducing the cost of using temperature sensors.

[0115] Alternatively, the indoor temperature can be determined by acquiring temperature data from sensors installed at different locations within the indoor space (such as walls, ceilings, or floors). This temperature data is then transmitted to a control device. The control device determines the temperature data characteristics based on the data from each sensor and uses these characteristics to derive the indoor temperature. For example, it might determine the average temperature based on the data from all sensors and use this average temperature as the indoor temperature. Because the indoor temperature is determined using temperature data from sensors placed in different indoor spaces, the error inherent in individual sensors is reduced, improving the accuracy of the indoor temperature readings. Furthermore, it avoids the impact of temperature unevenness at different locations within the indoor space on the accuracy of the indoor temperature readings. Alternatively, remote monitoring and control can be achieved through mobile applications, web interfaces, or other smart devices. In these systems, users can view the indoor temperature to obtain its accuracy.

[0116] In this embodiment, the heat supply of the second terminal device can be controlled based on the comparison between the indoor temperature and the set temperature of the second terminal device.

[0117] In this embodiment, the heating output of the first terminal device is controlled according to the area temperature and the set temperature of the first terminal device, and the heating output of the second terminal device is controlled according to the indoor temperature and the set temperature of the second terminal device. This allows the heating output of the first terminal device and the heating output of the second terminal device to be controlled independently without mutual restriction, thereby improving the heating effect of the environmental control system and enhancing indoor comfort.

[0118] Based on the second embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the second embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, step S21 includes steps S211 and / or S212:

[0119] In one possible implementation, step S21 includes step S211:

[0120] Step S211: When the temperature of the area and the set temperature of the first terminal device meet the first condition, control the heating system to reduce the heat supply of the first terminal device;

[0121] The first condition includes a regional temperature greater than or equal to the set temperature of the first terminal device, or a regional temperature greater than or equal to the set temperature of the first terminal device and a duration greater than a first preset duration.

[0122] The first preset duration can be a factory-set value, which represents the duration after the first terminal device reaches the set value or comfortable temperature. The value range of the first preset duration is 0~120min, preferably 30min.

[0123] In this embodiment, by means of the above method, when the area temperature is greater than or equal to the set temperature of the first terminal device, the heating system is controlled to reduce the heat supply of the first terminal device to lower the indoor temperature and avoid overheating. When the area temperature is greater than or equal to the set temperature of the first terminal device and the duration is longer than a first preset duration, the heating system is controlled to reduce the heat supply of the first terminal device to lower the indoor temperature, avoid overheating, and improve indoor comfort.

[0124] Furthermore, in one embodiment, controlling the heating system to reduce the heat output of the first terminal device includes controlling the fluid regulation module to shut down.

[0125] The fluid regulation module is configured to connect to at least two of the first terminal devices to regulate the refrigerant flow rate of each first terminal device. The fluid regulation module includes multiple sub-regulation modules, namely water distribution valves, which regulate the refrigerant flow rate into the first terminal devices by adjusting the opening degree of the water distribution valves. When the refrigerant flow rate decreases, the heating supply decreases; when the refrigerant flow rate increases, the heating supply increases. The module can control the partial closure of the water distribution valves to reduce the heating supply of the first terminal devices, or control the closure of all water distribution valves to reduce the heating supply of the first terminal devices.

[0126] In this embodiment, the number of sub-regulating modules to be shut down or the opening degree of the sub-regulating modules can be determined based on the temperature difference between the current area temperature and the set temperature of the first terminal device. Alternatively, the number of sub-regulating modules to be shut down or the opening degree of the sub-regulating modules can be determined based on the current area temperature, the set temperature of the first terminal device, and / or the indoor temperature detected in the area where the second terminal device is located. This allows for reasonable control of the fluid regulating modules based on the indoor temperature conditions, thereby improving the stability of the indoor temperature.

[0127] In this embodiment, by means of the above method, when the temperature of the area and the set temperature of the first terminal device meet the first condition, the control fluid regulation module is turned off to reduce the heat supply of the first terminal device, avoid indoor overheating, and improve indoor comfort.

[0128] Furthermore, in one embodiment, after controlling the heating system to reduce the heat output of the first terminal device, the method further includes step S100:

[0129] Step S100: Control the operation of the fluid regulation module according to the temperature of the area.

[0130] In this embodiment, controlling the operation of the fluid regulation module includes at least one of the following: controlling the fluid regulation module to turn on, and maintaining the fluid regulation module on.

[0131] In this embodiment, the operating status of the fluid regulation module can be controlled based on the comparison between the regional temperature of the first terminal device installation area and a preset value, thereby realizing intelligent regulation and control of the indoor temperature.

[0132] In one embodiment, when the area temperature meets the second condition, the heating supply of the second terminal device is controlled according to the indoor temperature status parameter and the set temperature of the second terminal device; and / or, when the area temperature does not meet the second condition, the control fluid regulation module is turned on to control the first terminal device to increase the heating supply.

[0133] The second condition includes the area temperature being greater than the first preset value, or the temperature difference between the set temperature of the first terminal device and the area temperature being less than the second preset value.

[0134] The first preset value can be a fixed value or it can be determined according to the operating status of the environmental control system. The first preset value can also be determined based on the set temperature of the first terminal device and the temperature drop hysteresis of the first terminal device. For example, the first preset value can be obtained based on the temperature difference between the set temperature of the first terminal device and the temperature drop hysteresis of the first terminal device, wherein the temperature drop hysteresis of the first terminal device ranges from 0 to 20°C, preferably 0°C.

[0135] The second preset value can be a fixed value. The second preset value represents the temperature drop hysteresis of the first terminal device, and its value range is 0~20℃, preferably 0℃.

[0136] The fluid regulation module is configured to connect to at least two of the first terminal devices to regulate the refrigerant flow rate of each first terminal device. The fluid regulation module includes multiple sub-regulation modules, namely water distribution valves, which regulate the refrigerant flow rate into the first terminal devices by adjusting the opening degree of the water distribution valves. When the refrigerant flow rate decreases, the heating supply decreases; when the refrigerant flow rate increases, the heating supply increases. It is possible to control the opening of some water distribution valves to increase the heating supply of the first terminal devices, or to control the opening of all water distribution valves to increase the heating supply of the first terminal devices.

[0137] In this embodiment, the number of sub-regulation modules to be activated or the opening degree of the sub-regulation modules can be determined based on the temperature difference between the current area temperature and the set temperature of the first terminal device. Alternatively, the number of sub-regulation modules to be activated or the opening degree of the sub-regulation modules can be determined based on the current area temperature, the set temperature of the first terminal device, and / or the indoor temperature detected in the area where the second terminal device is located. This allows for reasonable control of the fluid regulation modules based on the indoor temperature conditions, thereby improving the stability of the indoor temperature.

[0138] In this embodiment, by means of the above method, when the area temperature is greater than or equal to the first preset value, or the temperature difference between the set temperature of the first terminal device and the area temperature is less than the second preset value, it indicates that the current indoor temperature meets the temperature requirements. At this time, the heating supply of the second terminal device can be controlled according to the indoor temperature status parameters and the set temperature of the second terminal device; and / or, when the area temperature is less than or equal to the second preset value, or the temperature difference between the set temperature of the first terminal device and the area temperature is greater than or equal to the second preset value, it indicates that the current indoor temperature does not meet the temperature requirements, and the fluid regulation module needs to be turned on to control the first terminal device to increase the heating supply.

[0139] In one possible implementation, step S21 includes step S212:

[0140] Step S212: When the temperature of the area and the set temperature of the first terminal device do not meet the first condition, control the heating system to maintain or increase the heat supply of the first terminal device.

[0141] In this embodiment, by means of the above method, when the area temperature is lower than the set temperature of the first terminal device, the heating system is controlled to maintain or increase the heat supply of the first terminal device to increase the indoor temperature and prevent the indoor temperature from becoming too cold. When the area temperature is greater than or equal to the set temperature of the first terminal device and the duration is less than a first preset duration, the heating system is controlled to maintain or increase the heat supply of the first terminal device to increase the indoor temperature, prevent the indoor temperature from becoming too cold, and improve indoor comfort.

[0142] Furthermore, in one embodiment, controlling the heating system to maintain or increase the heat supply of the first terminal device includes keeping the fluid regulation module on.

[0143] The fluid regulation module is configured to connect to at least two of the first terminal devices to regulate the refrigerant flow rate of each first terminal device. The fluid regulation module includes multiple sub-regulation modules, namely water distribution valves, which regulate the refrigerant flow rate into the first terminal devices by adjusting the opening degree of the water distribution valves. When the refrigerant flow rate decreases, the heating supply decreases; when the refrigerant flow rate increases, the heating supply increases. The module can control the opening of some water distribution valves to increase the heating supply of the first terminal devices, or control the opening of all water distribution valves to decrease the heating supply of the first terminal devices.

[0144] In this embodiment, the number of sub-regulation modules to be activated or the opening degree of the sub-regulation modules can be determined based on the temperature difference between the current area temperature and the set temperature of the first terminal device. Alternatively, the number of sub-regulation modules to be activated or the opening degree of the sub-regulation modules can be determined based on the current area temperature, the set temperature of the first terminal device, and / or the indoor temperature detected in the area where the second terminal device is located. This allows for reasonable control of the fluid regulation modules based on the indoor temperature conditions, thereby improving the stability of the indoor temperature.

[0145] In this embodiment, by means of the above method, when the temperature of the area and the set temperature of the first terminal device do not meet the first condition, the fluid regulation module is controlled to remain on to increase the heat supply of the first terminal device, thereby avoiding excessive cold indoors and improving indoor comfort.

[0146] Based on the second embodiment of this application, in the fourth embodiment of this application, the content that is the same as or similar to that in the second embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, step S22 includes steps S221 and / or S222:

[0147] In one possible implementation, step S22 includes step S221:

[0148] Step S221: When the indoor temperature meets the third condition, control the heat pump system to reduce the heat supply of the second terminal device.

[0149] The third condition includes one of the following: the indoor temperature is greater than or equal to a third preset value; the indoor temperature is greater than or equal to the third preset value and the duration is greater than a second preset duration; the temperature difference between the indoor temperature and the set temperature of the second terminal device is greater than or equal to a fourth preset value; and the temperature difference between the indoor temperature and the set temperature of the second terminal device is greater than or equal to the fourth preset value and the duration is greater than the second preset duration.

[0150] The third preset value can be determined based on the indoor temperature detected in the area where the second terminal device is located. For example, the third preset value is the maximum indoor temperature detected in the area where the second terminal device is located. The range of the third preset value is 20~40℃, preferably 33℃.

[0151] The second preset duration can be a factory-set value, which represents the duration after the indoor temperature detected in the area where the second terminal device is located reaches the maximum temperature. The value range of the second preset duration is 0~120min, preferably 30min.

[0152] The fourth preset value is the temperature rise difference of the indoor unit return air temperature of the second terminal device, and its value range is 0~20℃, preferably 1.0℃.

[0153] In this embodiment, controlling the heat pump system to reduce the heat supply of the second terminal device includes controlling the second terminal device to shut down, or controlling the second terminal device to lower its heating fan speed. Specifically, the second terminal device includes an indoor unit; controlling the indoor unit to shut down, or controlling the indoor unit to reduce its operating power in heating mode, can achieve the purpose of reducing the heat supply of the second terminal device.

[0154] In this embodiment, by means of the above method, when the indoor temperature meets the third condition, the heat pump system is controlled to reduce the heat supply of the second terminal device in order to avoid indoor overheating.

[0155] Furthermore, in one embodiment, after the step of controlling the heat pump system to reduce the heat supply of the second terminal device when the indoor temperature meets the third condition, the method further includes step S200:

[0156] Step S200: Control the heat supply of the second terminal device according to the area temperature and the indoor temperature.

[0157] In this embodiment, the heating output of the second terminal device can be controlled based on the comparison between the area temperature and the set temperature of the first terminal device, and the comparison between the indoor temperature and the set temperature of the second terminal device. This achieves intelligent control of the second terminal device to meet indoor temperature requirements.

[0158] Furthermore, in one embodiment, step S200 includes: when the area temperature does not meet the fourth condition and the indoor temperature meets the fifth condition, controlling the second terminal device to increase the heat supply.

[0159] In one feasible implementation, the fourth condition includes: the temperature difference between the set temperature of the first terminal device and the area temperature is less than a seventh preset value, or the area temperature is greater than or equal to an eighth preset value. The fourth condition further includes: the temperature difference between the set temperature of the first terminal device and the area temperature is less than the seventh preset value and lasts for a duration greater than a third preset duration, or the area temperature is greater than or equal to the eighth preset value and lasts for a duration greater than a third preset duration.

[0160] The seventh preset value is the hysteresis of the temperature drop of the first terminal equipment. The value of the hysteresis of the temperature drop of the first terminal equipment is in the range of 0~20℃, preferably 0.5℃.

[0161] The eighth preset value can be determined based on the set temperature of the first terminal device and the temperature drop hysteresis of the first terminal device. For example, the eighth preset value can be obtained based on the temperature difference between the set temperature of the first terminal device and the temperature drop hysteresis of the first terminal device.

[0162] The third preset duration is the indoor shutdown time of the second terminal device, with a value range of 0~120min, preferably 30min.

[0163] In another feasible implementation, the fifth condition includes: the indoor temperature is less than a ninth preset value, or the indoor temperature is less than a ninth preset value and the temperature difference between the indoor temperature and the set temperature of the second terminal device is less than a tenth preset value.

[0164] The ninth preset value is determined based on the maximum indoor temperature and the temperature drop difference of the indoor unit return air temperature of the second terminal device. For example, it is determined based on the temperature difference between the maximum indoor temperature and the temperature drop difference of the indoor unit return air temperature of the second terminal device. The maximum indoor temperature ranges from 20 to 40°C, preferably 33°C, and the temperature drop difference of the indoor unit return air temperature of the second terminal device ranges from 0 to 20°C, preferably 5°C.

[0165] The tenth preset value can be a fixed value or it can be set according to the operation of the environmental control system. For example, the tenth preset value can be a compensation value for indoor temperature.

[0166] In this embodiment, by means of the above method, when the area temperature does not meet the fourth condition and the indoor temperature meets the fifth condition, the second terminal device is controlled to increase the heat supply in order to improve the indoor temperature.

[0167] In another feasible implementation, step S22 includes step S222:

[0168] Step S222: When the indoor temperature does not meet the third condition, the heat supply of the second terminal device is controlled according to the changing trend of the indoor temperature and the temperature difference between the indoor temperature and the set temperature of the second terminal device.

[0169] The trend of indoor temperature change refers to the variation of indoor temperature over a period of time. It can be determined by recording the indoor temperature at each moment within a given period and subtracting the indoor temperatures from adjacent moments. Indoor temperature trends can be either upward or downward.

[0170] In this embodiment, it is necessary to obtain the indoor temperature change trend. This can be achieved by obtaining the indoor temperature at the current moment and the indoor temperature at the previous moment. The indoor temperature change trend is determined by comparing the temperature difference between the current and previous moments with a preset value. For example, the preset value can be set to 0. If the temperature difference between the current and previous moments is greater than or equal to 0, the indoor temperature change trend is determined to be upward; otherwise, if the temperature difference is less than 0, the indoor temperature change trend is determined to be downward. Determining the indoor temperature change trend facilitates the subsequent control of the second-terminal device.

[0171] In this embodiment, controlling the heat supply of the second terminal device includes at least one of the following: controlling the second terminal device to remain on, controlling the second terminal device to be off, etc.

[0172] In this embodiment, the trend of indoor temperature change can be determined first, and the temperature difference between the indoor temperature and the set temperature of the second terminal device can be obtained under the trend of change. The heat supply of the second terminal device can be controlled according to the temperature difference.

[0173] In this embodiment, by using the above method, a larger temperature difference between the indoor temperature and the set temperature of the second terminal device indicates a greater difference between the two temperatures. In this case, the heating output of the second terminal device needs to be increased to raise the indoor temperature. Conversely, a smaller temperature difference between the indoor temperature and the set temperature of the second terminal device indicates a smaller difference between the two temperatures. In this case, the heating output of the second terminal device can be reduced to avoid overheating. Therefore, the second terminal device can be reasonably controlled under different indoor temperature trends, improving indoor comfort.

[0174] Furthermore, in one embodiment, controlling the heating supply of the second terminal device based on the changing trend of the indoor temperature and the temperature difference between the indoor temperature and the set temperature of the second terminal device includes at least one of the following methods:

[0175] In one feasible implementation, when the indoor temperature is trending upward and the temperature difference is less than a fifth preset value, the second terminal device is controlled to remain on.

[0176] The fifth preset value is the hysteresis of the first terminal device's comfort temperature during supplemental heating, with a range of 0~20℃, preferably 1.0℃. The fifth preset value can also be the hysteresis or compensation value of the indoor unit of the second terminal device when it is turned on or off, with a range of 0~20℃, preferably 3℃. The value of the fifth preset value can be determined according to the actual situation.

[0177] In this embodiment, even if the indoor temperature is rising, if the temperature difference between the current temperature and the set temperature is still less than the fifth preset value, the room may still feel cool or comfortable. To maintain a comfortable indoor environment and prevent temperature changes from unnecessarily affecting people's feelings, the second-terminal device can be kept on. Furthermore, if the temperature difference is small, it indicates that the indoor temperature is close to the desired target temperature. In this case, the indoor unit may only need to operate at a lower power to maintain temperature stability, rather than operating at full power. In this situation, keeping the second-terminal device on can save energy and operating costs. Moreover, even if the indoor temperature is rising, if the indoor unit stops operating, the indoor temperature may continue to rise and exceed the set temperature. By keeping the second-terminal device on and operating it at a lower power, excessively high indoor temperatures can be prevented, thus avoiding adverse effects on people's comfort and health. In some cases, to ensure system stability and long-term operation, the second-terminal device may need to remain partially operational, even if the indoor temperature is trending upwards. This helps reduce the frequency of system start-ups and shutdowns, thereby extending the lifespan of the second-terminal device. Therefore, even though the indoor temperature is rising, keeping the second-terminal device on may help maintain a comfortable indoor environment, save energy, and ensure stable system operation when the difference between the indoor temperature and the set temperature is small.

[0178] In another feasible implementation, when the indoor temperature is trending upward and the temperature difference is greater than or equal to the fifth preset value, the second terminal device is controlled to shut down.

[0179] In this embodiment, when the difference between the indoor temperature and the set temperature is greater than a preset value, the indoor environment may already be relatively warm. Turning off the second-terminal device can prevent overheating of the indoor environment, saving energy and reducing energy costs. If the second-terminal device continues to operate, the indoor temperature may continue to rise, exceeding the comfort range and causing overheating. By turning off the second-terminal device in a timely manner, the indoor temperature can be prevented from rising further, maintaining a comfortable indoor environment. When the difference between the indoor temperature and the set temperature is large, continuous operation of the second-terminal device may lead to over-adjustment, i.e., the indoor temperature exceeds the set temperature and continues to rise. By turning off the second-terminal device, over-adjustment can be avoided and the temperature can be maintained within a suitable range. In addition, prolonged continuous operation of the second-terminal device may increase wear and tear on the device and shorten its lifespan. Regularly turning off the second-terminal device can reduce the device's usage time, extend its lifespan, and reduce maintenance costs. Therefore, when the indoor temperature is on an upward trend and the difference between it and the set temperature is greater than a preset value, turning off the second-terminal device can save energy, prevent overheating, avoid over-adjustment, and extend the device's lifespan, thereby maintaining a comfortable and cost-effective indoor environment.

[0180] In another feasible implementation, when the indoor temperature is trending downward and the temperature difference is less than or equal to a sixth preset value, the second terminal device is controlled to remain on.

[0181] The sixth preset value is the temperature drop hysteresis of the first terminal device, with a range of 0~20℃, preferably 0℃. The sixth preset value can also be the temperature hysteresis or compensation value of the indoor unit of the second terminal device when it is turned on or off, with a range of -10~10℃, preferably -3℃.

[0182] In this embodiment, even if the indoor temperature is decreasing, if the difference between the indoor temperature and the set temperature remains small, it indicates that the indoor temperature is close to the desired target temperature. In this case, continuously running the indoor unit ensures that the indoor temperature remains within a comfortable range, preventing excessively low temperatures from affecting people's comfort. Furthermore, continuous operation of the indoor unit helps stabilize the indoor temperature and prevents excessive temperature fluctuations. Even if the indoor temperature is decreasing, continuous heating can slow the rate of temperature drop, making the indoor temperature more stable. Additionally, even if the difference between the indoor temperature and the set temperature is small, people may still feel cold when the temperature begins to drop. Continuously running the indoor unit prevents the indoor temperature from dropping to a level that causes discomfort. Moreover, some heating systems may be designed to remain operational when the temperature is close to the set temperature to avoid frequent start-ups and shutdowns, improving system efficiency and stability. In this case, even if the temperature begins to drop, the indoor unit may continue to operate to maintain the system's optimal state. Therefore, even if the indoor temperature is trending downwards, keeping the indoor unit running when the difference between the temperature and the set temperature is small ensures comfort, stability, and may align with the system's optimized design considerations.

[0183] In another feasible implementation, when the indoor temperature is trending downward and the temperature difference is greater than the sixth preset value, the second terminal device is controlled to shut down.

[0184] In this embodiment, when the difference between the indoor temperature and the set temperature is large, continuous operation of the indoor unit may lead to overheating, thereby consuming unnecessary energy. By turning off the indoor unit, energy consumption can be reduced and energy costs lowered. Furthermore, if the indoor unit continues to run, the indoor temperature may continue to drop below the comfortable range. By turning off the indoor unit in a timely manner, excessively low indoor temperatures can be prevented, ensuring people's comfort and health. Additionally, when the difference between the indoor temperature and the set temperature is large, continuous operation of the indoor unit may lead to over-adjustment, i.e., the indoor temperature falls below the set temperature and continues to drop. By turning off the indoor unit, over-adjustment can be avoided, maintaining the indoor temperature within a suitable range. Moreover, prolonged continuous operation of the indoor unit may increase equipment wear and shorten its lifespan. Regularly turning off the indoor unit can reduce equipment usage time, extend its lifespan, and reduce maintenance costs. Therefore, when the indoor temperature is trending downwards and the difference between the indoor temperature and the set temperature is greater than a preset value, turning off the indoor unit can save energy, prevent overheating, avoid over-adjustment, and extend equipment lifespan, thereby maintaining a comfortable and cost-effective indoor environment.

[0185] In another feasible implementation, step S22 includes: when the indoor temperature meets the third condition, controlling the heat pump system to reduce the heat supply of the second terminal device; when the indoor temperature does not meet the third condition, controlling the heat supply of the second terminal device according to the changing trend of the indoor temperature and the temperature difference between the indoor temperature and the set temperature of the second terminal device. This achieves intelligent adjustment of the heat pump system.

[0186] Based on any of the above embodiments of this application, in the fifth embodiment of this application, the content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, the control method of the environmental control system further includes step 300:

[0187] Step S300: When the area temperature is less than the first comfort temperature threshold and the indoor temperature is less than the second comfort temperature threshold, execute the step of controlling both the first terminal device and the second terminal device to run in heating mode.

[0188] The first comfort temperature threshold is the comfort temperature threshold of the first terminal device during heat replenishment, and its value ranges from 15 to 30°C, preferably 24°C.

[0189] The second comfort temperature threshold is the comfort temperature threshold of the second terminal device during heat replenishment, and its value ranges from 15 to 35°C, preferably 28°C.

[0190] In this embodiment, by means of the above method, when the temperature of the area where the first terminal device is installed is less than the first comfort temperature threshold and the indoor temperature of the area where the second terminal device is located is less than the second comfort temperature threshold, it indicates that the current indoor temperature has not met the comfort requirements. The second terminal device and the first terminal device can be controlled to operate in heating mode to increase the indoor temperature so that the indoor temperature meets the comfort requirements and improve the comfort of the indoor temperature.

[0191] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the control method of the environmental control system of this application.

[0194] The aforementioned computer-readable storage medium may be included in the environmental control system; or it may exist independently and not be assembled into the environmental control system.

[0195] The aforementioned computer-readable storage medium carries one or more programs that, when executed by the environmental control system, cause the environmental control system to: control both the first terminal device and the second terminal device to operate in heating mode, and acquire indoor temperature status parameters; control the heat supply of the first terminal device according to the indoor temperature status parameters and the set temperature of the first terminal device, and control the heat supply of the second terminal device according to the indoor temperature status parameters and the set temperature of the second terminal device.
