Description

Technical Field

[0001] This application relates to the field of environmental control system technology, and in particular to control methods, systems and storage media for environmental control systems. Background Technology

[0002] Some environmental control systems combine heat pump systems with heating systems, using the heat pump system to provide heat or cooling to the terminal units of the heating system. Typically, a temperature sensor located on the room thermostat or the indoor unit's return air vent is used to detect the indoor temperature and control both the heat pump and heating systems. Because heating systems heat up slowly while heat pump systems heat up quickly, using a single temperature sensor to control the same room can lead to mutual interference, thus affecting the heating output. The above description is only for illustrative purposes and does not constitute an admission that the above content is prior art. Summary of the Invention

Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0037] Figure 3This is a flowchart illustrating an embodiment of the control method for the environmental control system of this application.

[0038] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0040] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The main solution of this application embodiment is: to obtain the regional temperature of the installation area of ​​the first terminal device and the indoor temperature detected in the area where the second terminal device is located; when the regional temperature does not meet the first condition of sufficient heat, to control the operation of the heating system so that the heat supply of the first terminal device is greater than the preset heat; when the indoor temperature does not meet the second condition of sufficient heat, to control the operation of the heat pump system so that the heat supply of the second terminal device is greater than the preset heat.

[0042] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0043] Because existing heating systems heat up slowly while heat pump systems heat up quickly, using a single temperature sensor to monitor the indoor temperature in the same room for joint control of the heat pump and heating systems will cause them to restrict each other, thus affecting the heating output.

[0044] This application provides a solution that, by setting a first condition and a second condition, controls the operation of the heating system to ensure that the heat output of the first terminal device is greater than the preset heat output when the area temperature does not meet the first condition, and controls the operation of the heat pump system to ensure that the heat output of the second terminal device is greater than the preset heat output when the indoor temperature does not meet the second condition. By setting the first condition and the second condition respectively for judgment and controlling the first terminal device and the second terminal device respectively, 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.

[0045] 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.

[0054] The heating system 200 is filled with a refrigerant that can flow within it. In this embodiment, the refrigerant is water. In other embodiments, the refrigerant may also be an aqueous solution of sodium chloride or calcium chloride salt, or an aqueous solution of an organic compound such as ethylene glycol or glycerol, etc.

Indoor terminal devices include second terminal devices (including indoor units, which in turn include indoor fans) or first terminal devices 24 (e.g., radiators, underfloor heating, etc.). The second terminal device includes an indoor unit 11 and a heat exchanger, wherein the indoor unit includes an indoor fan. The number of indoor terminal devices can be one or more, and more than one indoor terminal device can be installed in different indoor spaces.

For example, the environmental control system is configured to regulate at least two indoor spaces, each indoor space equipped with a first terminal device 24, or each indoor space equipped with both a second terminal device and a first terminal device 24, or each indoor space equipped with a second terminal device.

[0056] The gas appliance 21 can heat the refrigerant flowing through it by burning gas. The gas appliance 21 can be a gas water heater or a gas wall-hung boiler, etc.

[0057] The location of the first terminal device can be set according to the actual situation, for example, at the bottom of the indoor space or in other locations within the indoor space.

The fluid regulation module 23 includes at least two sub-regulation modules 22, each corresponding to a first terminal device 24. Each sub-regulation module 22 can be configured to control the flow rate of refrigerant in its corresponding first terminal device 24. When a sub-regulation module 22 is open, refrigerant is allowed to flow into the corresponding first terminal device 24; when a sub-regulation module 22 is closed, refrigerant flow into the corresponding first terminal device 24 is stopped. In this embodiment, the fluid regulation module 23 is a manifold, and the sub-regulation module 22 is a distribution valve within the manifold.

[0059] Furthermore, refer to Figure 1In one implementation, the heating system 200 includes a refrigerant circulation loop and a heat exchange device. The gas appliance 21, the heat exchange device, the fluid regulation module 23, and the first terminal device 24 are located in the refrigerant circulation loop.

The heating capacity of the gas appliance 21 is greater than or equal to the cold energy released by the second heat exchanger.

[0077] 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.

[0078] In this embodiment, the control method of the environmental control system includes steps S10 to S20:

[0079] Step S10: Obtain the regional temperature of the first terminal device installation area and the indoor temperature detected in the area where the second terminal device is located;

[0080] In this embodiment, the installation area of ​​the first terminal device refers to the installation location of the first terminal device in the indoor space.

[0081] 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.

[0082] The installation area of ​​the first terminal device can be set at the bottom of the indoor space, the top of the indoor space, or other locations in the indoor space. The temperature of the installation area of ​​the first terminal device can be obtained from the bottom of the indoor space, or the temperature of the installation area of ​​the first terminal device can be obtained from the top of the indoor space, etc.

[0083] In one embodiment, the first terminal device is located at the bottom of the indoor space, and obtaining the area temperature of the area where the first terminal device is installed includes obtaining the floor temperature of the indoor space, wherein the area temperature includes the floor temperature.

[0084] Temperature sensors can be installed at different locations on the floor of the indoor space. The control device acquires temperature data from these sensors at different locations and calculates the average temperature. This average temperature is used as the area temperature to avoid errors from single-sensor data and improve the accuracy of the floor temperature readings. Alternatively, the floor of the indoor space can be pre-divided into different blocks. A corresponding temperature sensor can be installed in each block. Taking each block as the center, temperature data from the sensors in the current central block and the blocks in the eight adjacent directions are acquired. The average of these eight directions' temperature data is calculated and used as the block temperature for the current central block. Each block can calculate its own block temperature using the same method. After obtaining the block temperatures for each block, the average of these block temperatures is calculated to obtain the floor temperature of the indoor space, i.e., the area temperature. This method can correct the temperature in each block, improving the accuracy of the block temperature readings for each block, and thus improving the accuracy of the area temperature readings.

[0085] In one embodiment, the first terminal device may also be installed at the top of the indoor space, and the temperature at the top of the indoor space can be obtained to obtain the area temperature of the area where the first terminal device is installed.

[0086] By using the floor temperature of the indoor space as the area temperature of the first-terminal device's installation zone, in heating mode, the second-terminal device, whose air outlet is typically located at a higher position in the indoor space, experiences hot air primarily affecting the upper part of the space. This design can sometimes lead to temperature stratification, with the upper part of the space being warmer and the area near the floor being cooler. Consequently, the temperature felt by the human body primarily comes from the upper part of the body. In contrast, the first-terminal device, by laying pipes at the bottom of the indoor space, conducts heat generated by hot water or electric heating elements to the floor. Compared to the second-terminal device's heating method, it can evenly distribute heat throughout the room through floor radiation. This first-terminal device heating method not only results in a more uniform indoor air temperature distribution but also, because heat is transferred from bottom to top, it aligns with human physiological needs, improving the comfort of occupants.

[0087] In this embodiment, indoor temperature refers to the air temperature of the indoor space where the first terminal device is located.

[0088] 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.

[0089] 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 ranges from -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.

[0090] 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 a single sensor 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.

[0091] Step S20: When the temperature of the area does not meet the first condition of sufficient heat, control the heating system to operate so that the heat supply of the first terminal device is greater than the preset heat. When the indoor temperature does not meet the second condition of sufficient heat, control the heat pump system to operate so that the heat supply of the second terminal device is greater than the preset heat.

[0092] The preset heat capacity can be fixed, for example, set to 70%-80% of the maximum heat capacity. Alternatively, the preset heat capacity can be determined based on the actual operating conditions of the environmental control system, for example, based on the temperature difference between the zone temperature and the set temperature of the first terminal device and / or the temperature difference between the indoor temperature and the set temperature of the second terminal device, or based on the total number of the first and second terminal devices, etc. The preset heat capacity should be a relatively large value.

[0093] In this embodiment, when the area temperature does not meet the first condition of sufficient heat, indicating insufficient area temperature, the heating system is controlled to operate so that the heat output of the first terminal device is greater than the preset heat output, thus enabling the first terminal device to output a larger amount of heat. When the indoor temperature does not meet the second condition of sufficient heat, indicating insufficient indoor temperature, the heat pump system is controlled to operate so that the heat output of the second terminal device is greater than the preset heat output, thus enabling the second terminal device to output a larger amount of heat.

[0094] By controlling the heat output of the first terminal device to be greater than the preset heat output and the heat output of the second terminal device to be greater than the preset heat output, the indoor temperature is increased, thereby meeting the temperature requirements and improving indoor comfort.

[0095] In this embodiment, corresponding preset values ​​can be set for the area temperature and the indoor temperature respectively. The comparison result between the area temperature and the corresponding preset value is used to determine whether the area temperature meets the first condition of sufficient heat. The comparison result between the indoor temperature and the corresponding preset value is used to determine whether the indoor temperature meets the second condition of sufficient heat.

[0096] This embodiment provides a control method for an environmental conditioning system. By setting a first condition and a second condition, when the area temperature does not meet the first condition, the heating system is controlled to operate so that the heat output of the first terminal device is greater than the preset heat output. When the indoor temperature does not meet the second condition, the heat pump system is controlled to operate so that the heat output of the second terminal device is greater than the preset heat output. By setting the first condition and the second condition respectively for judgment and controlling the first terminal device and the second terminal device respectively, 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 conditioning system.

[0097] 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, in step S20, controlling the operation of the heating system to make the heat supply of the first terminal device greater than the preset heat supply includes: controlling the gas equipment to operate in heating mode according to the target refrigerant temperature, wherein the target refrigerant temperature is greater than the preset temperature.

[0098] The aforementioned refrigerant temperature includes at least one of the following: the supply temperature of the fluid regulating module, the return temperature of the fluid regulating module, the inlet temperature of the indoor terminal device, and the outlet temperature of the indoor terminal device. The fluid regulating module is configured to be connected to at least two of the indoor terminal devices to regulate the refrigerant flow rate of each indoor terminal device.

[0099] The supply temperature of the fluid regulating module is specifically the total supply temperature of the refrigerant flowing from the fluid regulating module to at least two indoor terminal devices, and the return temperature of the fluid regulating module is the total return temperature of the refrigerant flowing from at least two indoor terminal devices back to the fluid regulating module. In this embodiment, the fluid regulating module is a manifold.

[0100] In this embodiment, the refrigerant temperature is the supply temperature of the fluid conditioning module.

[0101] The target refrigerant temperature is the desired temperature that the refrigerant in the refrigerant circulation system must reach during the operation of the gas-fired equipment. The target refrigerant temperature is lower than the aforementioned target outlet temperature. The target refrigerant temperature can vary depending on the detection location. The target refrigerant temperature can be a pre-set fixed temperature or a temperature determined based on the actual operating conditions of the environmental control system.

[0102] The heating capacity of the gas equipment is controlled by the magnitude or quantitative relationship (such as difference or ratio) between the refrigerant temperature and the target refrigerant temperature.

[0103] In this embodiment, the gas-fired equipment is controlled to increase the heating amount in order to increase the target refrigerant temperature.

[0104] Controlling the gas-fired equipment to increase its heating capacity may include at least one of the following: controlling the gas-fired equipment to increase the opening of the gas proportional valve to increase the amount of gas in the combustion chamber; controlling the gas-fired equipment to increase the number of ignited burners; and controlling the gas-fired equipment to increase the amount of air in the combustion chamber. The operating parameter adjustment values ​​during the process of increasing the heating capacity of the gas-fired equipment can be pre-set fixed parameters, or values ​​determined based on the actual operating conditions of the environmental control system. For example, the operating parameter adjustment values ​​can be determined based on the temperature difference between the refrigerant temperature and the target refrigerant temperature, / or the temperature change value of the first heat exchanger within a preset time period, and / or the frost thickness of the first heat exchanger when the defrosting mode is activated, etc.

[0105] In this embodiment, the preset temperature can be fixed or determined according to the operation of the environmental control system. The target refrigerant temperature is greater than the preset temperature. By controlling the heating operation of the gas equipment, the target refrigerant temperature is made to be greater than the preset temperature, so that the target refrigerant temperature reaches a larger output value and the indoor temperature is increased.

[0106] Furthermore, in one embodiment, the target refrigerant temperature includes the maximum refrigerant temperature, that is, controlling the gas equipment to operate in heating mode so that the refrigerant temperature reaches the maximum refrigerant temperature, thereby enabling the indoor temperature to increase rapidly.

[0107] Controlling the heating operation of the gas equipment to achieve the maximum refrigerant temperature may include at least one of the following: adjusting the opening of the gas proportional valve of the gas equipment to the maximum value to achieve the maximum refrigerant temperature; controlling the number of burners ignited in the gas equipment to the maximum to achieve the maximum refrigerant temperature; and controlling the amount of air in the combustion chamber of the gas equipment to the maximum allowable amount of air to achieve the maximum refrigerant temperature.

[0108] In this embodiment, the refrigerant temperature is increased to the maximum refrigerant temperature by controlling the heating operation of the gas equipment, thereby improving the rate of indoor temperature rise.

[0109] Furthermore, in one embodiment, after obtaining the regional temperature of the first terminal device installation area and the indoor temperature detected in the area where the second terminal device is located, the method further includes:

[0110] Step S100: When the temperature of the area meets the first condition, control the fluid regulation module to shut down;

[0111] Step S200: When the temperature of the area does not meet the first condition, control the fluid regulation module to turn on and execute the step of controlling the operation of the heating system to make the heat supply of the first terminal device greater than the preset heat supply.

[0112] The first condition includes: the temperature of the area is greater than or equal to a ninth preset value, or the temperature of the area is greater than or equal to a ninth preset value and the duration reaches a first preset duration, or the temperature of the area is greater than or equal to a tenth preset value, or the temperature of the area is greater than or equal to a tenth preset value and the duration reaches the first preset duration.

[0113] When the above preset conditions are met, the heat storage of the indoor space envelope is sufficient, and the heating demand can be met by the radiant terminal equipment alone. Therefore, the supplementary heating function is deactivated, and the original control is restored. Otherwise, if a fluid regulation module is not activated, it will be forced to activate. If the refrigerant temperature has not reached its maximum value, the refrigerant temperature of the fluid regulation module will be forced to its maximum value, operating at maximum output to improve heat exchange of the gas equipment and accelerate underfloor heating. When the gas equipment is connected to different terminals, different maximum refrigerant values ​​are corresponding to them; for example, 60℃ corresponds to underfloor heating, and 80℃ corresponds to radiators.

[0114] In this embodiment, the fluid regulation module is shut down when the area temperature is greater than or equal to a ninth preset value; or, when the area temperature is greater than or equal to the ninth preset value and the duration reaches a first preset duration; or, when the area temperature is greater than or equal to a tenth preset value; or, when the area temperature is greater than or equal to the tenth preset value and the duration reaches a first preset duration. It is understood that when the fluid regulation module is shut down, the refrigerant flow rate decreases, resulting in a decrease in heating capacity and consequently a decrease in indoor temperature. Conversely, when the fluid regulation module is turned on, the refrigerant flow rate increases, resulting in an increase in heating capacity and consequently a increase in indoor temperature.

[0115] Furthermore, in one embodiment, after the step of controlling the fluid regulation module to shut down when the area temperature meets the first condition, the method further includes: controlling whether the fluid regulation module is turned on based on the area temperature and / or the temperature difference between the set value of the environmental regulation system and the area temperature.

[0116] In one feasible implementation, when the regional temperature is less than a first preset value, the fluid regulation module can be turned on and the heating system can be controlled to operate so that the heat supply of the first terminal device is greater than the preset heat supply.

[0117] The first preset value can be a fixed value, which can be determined based on the temperature drop hysteresis between the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. For example, the first preset value can be obtained based on the difference between the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. The temperature drop hysteresis of the first terminal device is in the range of 0 to 20°C, preferably 0°C.

[0118] In this embodiment, when the area temperature is lower than the first preset value, it indicates that the indoor temperature is low. At this time, the control fluid regulation module is turned on, which can increase the refrigerant flow and increase the heating. By controlling the heating of the first terminal device to be greater than the preset heating, the first terminal device outputs a larger heating capacity. By controlling the operation of the control fluid regulation module and the heating system, the indoor temperature can be increased rapidly, thus improving the heating effect.

[0119] In another feasible implementation, when the temperature difference between the set temperature of the environmental control system and the area temperature is greater than a second preset value, the fluid control module can be turned on and the heating system can be controlled to operate so that the heat supply of the first terminal device is greater than the preset heat supply.

[0120] The second preset value here can be 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.

[0121] The set temperature of the environmental control system here can be a value set by the user, or it can be determined based on the operating conditions of the environmental control system.

[0122] In this embodiment, when the temperature difference between the set temperature of the environmental control system and the area temperature is greater than the second preset value, it indicates that the area temperature and the set temperature of the environmental control system are significantly different, meaning that the room may be too cold. In this case, the fluid regulation module is activated to increase the refrigerant flow rate and thus increase the heating capacity. At the same time, the heating system is activated to ensure that the heating capacity of the first terminal device is greater than the preset heating capacity, thereby enabling the first terminal device to output a larger heating capacity. By controlling the activation of the fluid regulation module and the combined operation of the heating system, the indoor temperature can be rapidly increased, thus improving the heating effect.

[0123] Based on the first embodiment of this application, in the third 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, in step S20, the second terminal device includes an indoor unit, the indoor unit includes an indoor fan, and controlling the operation of the heat pump system to make the heat supply of the second terminal device greater than the preset heat supply includes: controlling the indoor fan to operate at a target speed for heating, the target speed being greater than the preset speed.

[0124] When the area temperature does not meet the second condition of sufficient heat, it indicates that the area temperature is insufficient for heat supply. In this case, it is necessary to control the operation of the heat pump system to enable the second-terminal device to output a larger amount of heat. In this embodiment, the heating capacity of the second-terminal device is increased by controlling the speed of the indoor fan. Since the target speed is greater than the preset speed, the indoor fan can rotate at a higher target speed, which can quickly increase the heating capacity of the second-terminal device and raise the indoor temperature.

[0125] When the indoor fan operates at its target speed for heating, it increases the air circulation speed, thereby improving the heat exchange efficiency between the indoor air and the indoor unit's heat exchanger (evaporator). As the indoor fan speed increases, the airflow velocity increases, leading to a larger contact area between the air and the heat exchanger surface, thus improving heat exchange efficiency. More air passing through the heat exchanger can carry away heat more quickly, causing the indoor air temperature to rise rapidly. Furthermore, increasing the fan speed accelerates the air circulation within the room, allowing the indoor air to be heated and recirculated into the room more quickly. This reduces the time heat remains indoors, improving overall heating efficiency. Therefore, increasing the indoor fan speed can more effectively utilize the indoor unit's heating capacity, improving heating efficiency in air conditioning heating mode and enabling a rapid increase in indoor temperature.

[0126] Furthermore, in one embodiment, the target rotational speed includes the maximum rotational speed. That is, the heat pump system is controlled to operate at its maximum rotational speed so that the indoor fan speed reaches its maximum speed, thereby ensuring that the heat supply exceeds the preset heat supply and thus allowing the indoor temperature to increase rapidly.

[0127] Controlling the heat pump system to operate at its maximum speed includes at least one of the following: controlling the operating current, operating voltage, and / or operating power of the indoor fan to reach the maximum allowable value, so that the indoor fan speed reaches the maximum speed, thereby increasing the heat supply to the indoor space.

[0128] In this embodiment, by controlling the indoor fan speed to reach the maximum speed, the heat supply to the indoor space is increased, thereby improving the rate of temperature rise in the indoor space.

[0129] Furthermore, in one embodiment, after the steps of obtaining the regional temperature of the first terminal device installation area and the indoor temperature detected in the area where the second terminal device is located, the method further includes: controlling the indoor unit to shut down when the indoor temperature meets the second condition.

[0130] The second condition includes the indoor temperature being greater than or equal to the eleventh preset value and lasting for a duration of the second preset duration, or the indoor temperature being greater than or equal to the twelfth preset value and lasting for a duration of the second preset duration, or the temperature difference between the indoor temperature and the set temperature of the environmental control system being greater than or equal to the thirteenth preset value and lasting for a duration of the second preset duration.

[0131] In this embodiment, the indoor unit is shut down when the indoor temperature is greater than or equal to the eleventh preset value and the duration reaches the second preset duration. Alternatively, the indoor unit is shut down when the indoor temperature is greater than or equal to the twelfth preset value and the duration reaches the second preset duration. Or, the indoor unit is shut down when the temperature difference between the indoor temperature and the set temperature of the environmental control system is greater than or equal to the thirteenth preset value and the duration reaches the second preset duration. By shutting down the indoor unit, the heat supply to the indoor space is reduced, thereby lowering the indoor temperature.

[0132] In one embodiment, when the indoor temperature meets the second condition, the indoor fan speed can be reduced to lower the indoor temperature, thereby avoiding the problem of insufficient indoor temperature supply when the indoor fan is turned off and improving the stability of the indoor temperature.

[0133] Furthermore, in one embodiment, after controlling the indoor unit to shut down when the indoor temperature meets the second condition, the method further includes: controlling the operation of the indoor unit based on the zone temperature and the indoor temperature.

[0134] In this embodiment, the operating state of the indoor unit is determined based on the comparison between the zone temperature and the corresponding preset value, as well as the comparison between the indoor temperature and the corresponding preset value, thereby controlling the operation of the indoor unit. Alternatively, the zone temperature change rate can be determined based on the zone temperature, and the indoor temperature change rate can be determined based on the indoor temperature. The operating state of the indoor unit can then be controlled based on both the zone temperature change rate and the indoor temperature change rate, thus achieving operation control of the indoor unit.

[0135] In one feasible implementation, when the zone temperature does not meet the third condition but the indoor temperature meets the fourth condition, the indoor unit can be controlled to operate so that the heating output is greater than the preset heating output.

[0136] In one feasible implementation, the third condition includes: the temperature difference between the set temperature of the environmental control system and the area temperature is less than a third preset value, or the area temperature is greater than or equal to a fourth preset value, or the temperature difference between the comfort temperature threshold of the first terminal device and the area temperature is less than the third preset value, or the area temperature is greater than or equal to a fifth preset value.

[0137] The third preset value can be determined based on the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. For example, it can be determined based on the temperature difference between the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. The temperature drop hysteresis of the first terminal device is in the range of 0 to 20°C, preferably 0.5°C.

[0138] The fourth preset value can be the hysteresis of the temperature drop of the first terminal device, and the value range is as shown above.

[0139] The fifth preset value can be determined based on the comfort temperature threshold of the first terminal device and the temperature drop hysteresis of the first terminal device. For example, the fifth preset value can be obtained based on the temperature difference between the comfort temperature threshold of the first terminal device and the temperature drop hysteresis of the first terminal device. The comfort temperature threshold of the first terminal device is in the range of 15 to 30°C, preferably 24°C.

[0140] In one feasible implementation, the third condition further includes: the temperature difference between the set temperature of the environmental control system and the area temperature is less than a third preset value and lasts for a preset duration; or, the area temperature is greater than or equal to a fourth preset value and lasts for a preset duration; or, the temperature difference between the comfort temperature threshold of the first terminal device and the area temperature is less than the third preset value and lasts for a preset duration; or, the area temperature is greater than or equal to a fifth preset value and lasts for a preset duration. The preset duration is the indoor shutdown time, ranging from 0 to 120 minutes, preferably 30 minutes.

[0141] In another feasible implementation, the fourth condition includes: the indoor temperature is less than a sixth preset value, or the temperature difference between the maximum indoor temperature and the indoor temperature is greater than or equal to a seventh preset value, or the temperature difference between the indoor temperature and the set temperature of the environmental control system is less than an eighth preset value, or the temperature difference between the maximum indoor temperature and the indoor temperature is greater than or equal to the seventh preset value and the temperature difference between the indoor temperature and the set temperature of the environmental control system is less than the eighth preset value.

[0142] The sixth preset value is determined based on the difference between the maximum indoor temperature and the drop in the indoor unit return air temperature. For example, the sixth preset value is obtained based on the difference between the maximum indoor temperature and the drop in the indoor unit return air temperature. The maximum indoor temperature ranges from 20 to 40°C, preferably 33°C, and the drop in the indoor unit return air temperature ranges from 0 to 20°C, preferably 5°C.

[0143] The seventh preset value is the hysteresis difference of the indoor unit return air temperature drop, and its value range is shown above.

[0144] The eighth preset value is the indoor temperature compensation value.

[0145] In this embodiment, by setting different judgment conditions, the heat pump system can be effectively controlled based on the area temperature and the indoor temperature.

[0146] Based on any of the above embodiments of this application, in the fourth 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.

[0147] In one feasible implementation, the first condition includes: the temperature of the area is greater than or equal to a ninth preset value, or the temperature of the area is greater than or equal to a ninth preset value and the duration reaches a first preset duration, or the temperature of the area is greater than or equal to a tenth preset value, or the temperature of the area is greater than or equal to a tenth preset value and the duration reaches the first preset duration.

[0148] The aforementioned ninth preset value can be a fixed value, or it can be determined based on the comfort temperature threshold and the comfort temperature hysteresis of the first terminal device during supplemental heating. For example, the third preset value can be obtained by summing the comfort temperature threshold and the comfort temperature hysteresis of the first terminal device during supplemental heating. The comfort temperature threshold of the first terminal device during supplemental heating ranges from 15 to 30°C, preferably 24°C, and the comfort temperature hysteresis of the first terminal device during supplemental heating ranges from 0 to 20°C, preferably 1.0°C.

[0149] The aforementioned tenth preset value is determined based on the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. For example, the tenth preset value is obtained by summing the set temperature of the environmental control system and the temperature drop hysteresis of the first terminal device. The temperature drop hysteresis of the first terminal device ranges from 0 to 20°C, preferably 0°C.

[0150] The first preset duration can be a factory-set value, which represents the duration after the first terminal device reaches the set value or a comfortable temperature. The value of the first preset duration ranges from 0 to 120 minutes, with 30 minutes being preferred.

[0151] In this embodiment, through the above-described method, when the area temperature of the first terminal device is less than a ninth preset value, it indicates insufficient heat, and the heating system is controlled to operate so that the heat supply of the first terminal device exceeds the preset heat. Alternatively, when the area temperature of the first terminal device is greater than or equal to the ninth preset value and the duration is less than or equal to the first preset duration, it indicates insufficient heat, and the heating system is controlled to operate so that the heat supply of the first terminal device exceeds the preset heat. Alternatively, when the area temperature of the first terminal device is less than a tenth preset value, it indicates insufficient heat, and the heating system is controlled to operate so that the heat supply of the first terminal device exceeds the preset heat. Alternatively, when the area temperature of the first terminal device is greater than or equal to the tenth preset value and the duration is less than or equal to the first preset duration, it indicates insufficient heat, and the heating system is controlled to operate so that the heat supply of the first terminal device exceeds the preset heat, thus achieving intelligent control of the heat supply of the first terminal device.

[0152] In another feasible implementation, the second condition includes: the indoor temperature is greater than or equal to the eleventh preset value and the duration reaches the second preset duration; or, the indoor temperature is greater than or equal to the twelfth preset value and the duration reaches the second preset duration; or, the temperature difference between the indoor temperature and the set temperature of the environmental control system is greater than or equal to the thirteenth preset value and the duration reaches the second preset duration.

[0153] The eleventh preset value can be determined based on the indoor temperature detected in the area where the second terminal device is located. For example, the eleventh preset value is the maximum indoor temperature detected in the area where the second terminal device is located. The range of the eleventh preset value is 20 to 40°C, preferably 33°C.

[0154] The twelfth preset value is determined based on the set temperature of the environmental control system and the hysteresis of the indoor unit's return air temperature. For example, the twelfth preset value is obtained by summing the set temperature of the environmental control system and the hysteresis of the indoor unit's return air temperature. The range of the hysteresis of the indoor unit's return air temperature is 0 to 20°C, preferably 1.0°C.

[0155] The thirteenth preset value can be the difference between the rise and fall of the indoor unit's return air temperature.

[0156] 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 to 120 minutes, preferably 30 minutes.

[0157] In this embodiment, through the above-described method, when the indoor temperature is less than the eleventh preset value, it indicates insufficient indoor heat, and the heat pump system is controlled to operate so that the heat supply of the second terminal device exceeds the preset heat. Alternatively, when the indoor temperature is greater than or equal to the eleventh preset value and the duration does not reach the second preset duration, it indicates insufficient heat, and the heat pump system is controlled to operate so that the heat supply of the second terminal device exceeds the preset heat. Alternatively, when the indoor temperature is less than the twelfth preset value, it indicates insufficient indoor heat, and the heat pump system is controlled to operate so that the heat supply of the second terminal device exceeds the preset heat. Alternatively, when the indoor temperature is greater than or equal to the twelfth preset value and the duration does not reach the second preset duration, it indicates insufficient indoor heat, and the heat pump system is controlled to operate so that the heat supply of the second terminal device exceeds the preset heat. Alternatively, when the temperature difference between the indoor temperature and the set temperature of the environmental control system is less than the thirteenth preset value, the heat pump system is controlled to operate so that the heat supply of the second terminal device exceeds the preset heat, thus achieving intelligent control of the heat supply of the second terminal device.

[0158] 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. In addition, after step S10, step 300 is further included:

[0159] 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, the following steps are executed: when the area temperature does not meet the first condition of sufficient heat, control the heating system to operate so that the heat supply of the first terminal device is greater than the preset heat; when the indoor temperature does not meet the second condition of sufficient heat, control the heat pump system to operate so that the heat supply of the second terminal device is greater than the preset heat.

[0160] 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.

[0161] The second comfort temperature threshold is the comfort temperature threshold of the second terminal device during supplemental heating, and its value ranges from 15 to 35°C, preferably 28°C.

[0162] 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. When the area temperature does not meet the first condition of sufficient heat, the heating system is controlled to operate so that the heat supply of the first terminal device is greater than the preset heat. When the indoor temperature does not meet the second condition of sufficient heat, the heat pump system is controlled to operate so that the heat supply of the second terminal device is greater than the preset heat to increase the indoor temperature, so that the indoor temperature meets the comfort requirements and improves the comfort of the indoor temperature.

[0163] In other embodiments, when the temperature of the area where the first terminal device is installed is less than a first comfort temperature threshold and the indoor temperature of the area where the second terminal device is located is less than a second comfort temperature threshold, it indicates that the current indoor temperature does not meet the comfort requirements. The second terminal device and the first terminal device can be controlled to operate in heating mode first. Then, the temperature of the area where the first terminal device is installed and the detected indoor temperature in the area where the second terminal device is located are obtained. When the area temperature does not meet the first condition of sufficient heat, the heating system is controlled to operate so that the heat output of the first terminal device is greater than a preset heat output. When the indoor temperature does not meet the second condition of sufficient heat, the heat pump system is controlled to operate so that the heat output of the second terminal device is greater than the preset heat output.

[0164] In the heating mode of the first terminal device, the gas equipment heats the refrigerant flowing through it 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 transferred 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.

[0165] During the heating mode operation of the second terminal device, 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, absorbing heat released by the second heat exchanger as it flows through the heat exchange module before flowing to the second terminal device. When the second terminal device in the indoor space requiring heating is activated, it releases heat into the space it is in, thus achieving the heating effect.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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. Any simple modifications based on this technical concept are within the protection scope of this application.

[0175] 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.

[0176] 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: acquire the regional temperature of the area where the first terminal device is installed and the indoor temperature detected in the area where the second terminal device is located; when the regional temperature does not meet the first condition of sufficient heat, control the heating system to operate so that the heat supply of the first terminal device is greater than a preset heat supply; and when the indoor temperature does not meet the second condition of sufficient heat, control the heat pump system to operate so that the heat supply of the second terminal device is greater than the preset heat supply.

[0177] Computer program code for performing the operations of this application can be written in one or more programming languages ​​or a combination thereof, including object-oriented programming languages ​​such as Java, Smalltalk, and C++, and conventional procedural programming languages ​​such as the "C" language or similar programming languages. The program code can be executed entirely on the user's computer, partially on the user's computer, as a standalone software package, partially on the user's computer and partially on a remote computer, or entirely on a remote computer or server. In cases involving remote computers, the remote computer can be connected to the user's computer via any type of network—including a Local Area Network (LAN) or a Wide Area Network (WAN)—or can be connected to an external computer (e.g., via the Internet using an Internet service provider).

[0178] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of this application. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in the block diagrams and / or flowcharts, and combinations of blocks in the block diagrams and / or flowcharts, can be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0179] The modules described in the embodiments of this application can be implemented in software or hardware. The names of the modules do not necessarily limit the functionality of the unit itself.

[0180] The readable storage medium provided in this application is a computer-readable storage medium that stores computer-readable program instructions (i.e., a computer program) for executing the control method of the above-described environmental conditioning system. This solves the technical problem of mutual constraint between the control processes of the heat pump system and the heating system, resulting in poor heating performance. Compared with the prior art, the beneficial effects of the computer-readable storage medium provided in this application are the same as those of the control method of the environmental conditioning system provided in the above embodiments, and will not be repeated here.
