[0040] The main solution of this application embodiment is: controlling the operation of the radiant terminal device in heating mode; acquiring the indoor air temperature and the area temperature of the area where the radiant terminal device is installed; and controlling the operation of the convection heat exchange device based on the indoor air temperature and the area temperature.

[0041] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0042] Because existing heating systems heat up slowly while heat pump systems heat up quickly, and because the two systems operate independently without coordination, indoor overheating or undercooling can easily occur, affecting indoor comfort.

[0043] This application provides a solution in which, after the radiant terminal equipment is turned on for heating, the operation of the convection heat exchange equipment is controlled based on the indoor air temperature and the area temperature of the area where the radiant terminal equipment is installed. The indoor air temperature and the area temperature can accurately reflect the heating status of the radiant terminal equipment. Therefore, this control method can match the heating capacity of the convection heat exchange equipment with the heating status of the radiant terminal equipment. The two systems no longer work independently, but rather coordinate their heating to avoid overheating or overcooling indoors and improve indoor comfort.

[0044] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or environmental control system capable of performing the above functions. The following description uses an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0045] In this embodiment of the invention, an environmental control system is provided. (Refer to...) Figure 1 The environmental control system includes a heat pump system 100 and a heating system 200, with the heat pump system 100 and the heating system 200 connected for heat exchange.

[0046] The heat pump system 100 includes a compressor, a reversing assembly, a first heat exchanger, a throttling device, and a second heat exchanger, which are connected in sequence. The compressor's exhaust port, compressor's return port, the first heat exchanger, and the second heat exchanger are all connected to the reversing assembly. The heat pump system 100 also includes an indoor unit 11, which is connected in parallel with the second heat exchanger.

[0047] In this embodiment, the heat pump system 100 includes at least two indoor units 11, each including an indoor heat exchanger and a corresponding indoor fan. Different indoor units 11 are located in different indoor spaces. Each indoor unit 11 can be associated with at least one indoor terminal device, and the indoor unit 11 and its associated indoor terminal device are located in the same indoor space.

When the reversing assembly is operating in the first operating state, the compressor's exhaust port is connected to the indoor unit 11 and / or the second heat exchanger, and the compressor's return port is connected to the first heat exchanger; when the reversing assembly is operating in the second operating state, the compressor's exhaust port is connected to the first heat exchanger, and the compressor's return port is connected to the indoor unit 11 and / or the second heat exchanger.

[0050] When the reversing assembly is running in the first operating state, the refrigerant discharged by the compressor flows sequentially through the indoor unit 11 and / or the second heat exchanger, the throttling device, and the first heat exchanger before returning to the compressor. The indoor unit 11 and / or the second heat exchanger is in a heat release state, the first heat exchanger is in a heat absorption state, and the heat pump system 100 can be in a heating mode, etc.

[0051] When the reversing assembly is running in the second operating state, the refrigerant discharged by the compressor flows sequentially through the first heat exchanger, the throttling device, the indoor unit 11 and / or the second heat exchanger and then flows back to the compressor. The first heat exchanger is in a heat release state, and the indoor unit 11 and / or the second heat exchanger is in a heat absorption state. The heat pump system 100 can be in a cooling mode or a defrosting mode, etc.

[0052] The heating system 200 includes a gas appliance 21 and indoor terminal equipment. A fluid circulation module may be installed in the heating system 200 to drive the flow of refrigerant in the system.

[0053] 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.

[0054] Indoor terminal devices regulate the indoor environment by utilizing the cooling or heating output of a flowing refrigerant. Indoor terminal devices include convective heat exchange devices (e.g., fan coil units) or radiant terminal devices 24 (e.g., radiators, underfloor heating). The convective heat exchange device includes an indoor unit 11 and a heat exchanger, and 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 with a radiant terminal device 24, or each indoor space with both a convective heat exchange device and a radiant terminal device 24, or each indoor space with only a convective heat exchange device.

[0055] 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.

[0056] The location of the radiant terminal equipment 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.

Specifically, the fluid regulation module 23 can control the inflow or outflow of refrigerant into each radiant terminal device 24. The fluid regulation module 23 includes at least two sub-regulation modules 22, each corresponding to a radiant terminal device 24. Each sub-regulation module 22 can be configured to control the flow rate of refrigerant in its corresponding radiant terminal device 24.

In this embodiment, the fluid regulation module 23 is a manifold, and the sub-regulation module 22 is a distribution valve within the manifold.

[0058] Furthermore, refer to Figure 1 In one implementation, the heating system 200 includes a refrigerant circulation loop and a heat exchange device.

[0062] In the second temperature control mode, the heat pump system 100 operates in cooling mode, the gas equipment 21 is turned off, the refrigerant can absorb the cold energy in the second heat exchanger, and when the refrigerant flows to the radiant terminal equipment 24 and the convective heat exchange equipment, it releases the cold energy into the space where they are located.

[0064] In defrosting mode, the heat pump system 100 operates in defrosting mode, the gas appliance 21 is turned on, and the refrigerant can absorb the cold energy in the second heat exchanger and the heat energy in the gas appliance 21 respectively. The heating capacity of the gas appliance 21 is greater than or equal to the cold energy released by the second heat exchanger. When the refrigerant flows to the indoor terminal equipment, it can exchange heat with the indoor space.

The wired controller 300 may control at least one of the following: the liquid supply temperature of the sub-regulation module 22, gas equipment 21, and fluid regulation module 23, the ambient temperature of the indoor space, etc.

Simultaneously, the control unit's outdoor unit and the indoor units 11 in each room are connected via control and communication lines, and are also connected to the gas equipment 21 and the manifold control box 23 via communication lines.

[0069] Furthermore, refer to Figure 2The environmental control system may also include a control device 1, with the heating system 200 and the heat pump system 100 both connected to the control device 1. The control device 1 includes: at least one processor 1001; and a memory 1002 communicatively connected to the at least one processor 1001, as well as a timer 1003, etc.; wherein the memory 1002 stores instructions executable by the at least one processor 1001, which, when executed by the at least one processor 1001, enable the at least one processor 1001 to perform the control method of the environmental control system in the following embodiments.

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.

[0076] 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.

[0077] In this embodiment, the control method of the environmental control system includes steps S10 to S30:

[0078] Step S10: Control the radiant terminal device to operate in heating mode;

[0079] During the heating mode operation of the radiant terminal equipment, the gas equipment heats the refrigerant flowing through it by burning gas. The heated refrigerant then flows into the radiant terminal equipment in the corresponding indoor space through the fluid regulation module. After the corresponding sub-regulation module in the fluid regulation module is activated, the heated refrigerant releases heat, thus heating the air in the indoor space where the radiant terminal equipment is located. Then, after releasing heat, the cooled refrigerant returns to the gas equipment through a heat exchange device for recirculation and heating. Through continuous recirculation and heating, the indoor space where the radiant terminal equipment is located achieves the heating effect.

[0080] During the heating process of radiant terminal equipment, the heat pump system can be turned on or off. The heat pump system can be turned on in response to user commands, 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.

[0081] Step S20: Obtain the indoor air temperature and the area temperature of the radiant terminal device installation area;

[0082] Indoor air temperature refers to the air temperature in the indoor space where the radiant terminal equipment is located.

[0083] In this embodiment, the temperature collected by the temperature sensor installed in the convection heat exchanger can be used as the indoor air temperature.

[0084] 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 then uses these characteristics to derive the indoor air temperature. For example, it can determine the average temperature based on the data from all sensors and use this average temperature as the indoor air temperature. Because the indoor air temperature is determined by using temperature data from sensors installed in different parts of the indoor space, the error inherent in a single sensor is reduced, improving the accuracy of the indoor air temperature readings. Furthermore, it avoids the impact of temperature non-uniformity at different locations within the indoor space on the accuracy of the indoor air temperature readings, further enhancing the accuracy of the readings.

[0085] Alternatively, users can monitor and control the system remotely via mobile apps, web interfaces, or other smart devices. These systems allow users to view and obtain indoor air temperature data.

[0086] The installation area of ​​the radiant terminal equipment indicates the location of the radiant terminal equipment in the indoor space.

[0087] In this embodiment, the installation area of ​​the radiant 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 radiant terminal device can be obtained from the bottom temperature of the indoor space, or the temperature of the installation area of ​​the radiant terminal device can be obtained from the top temperature of the indoor space, etc.

[0088] Step S30: Control the operation of the convection heat exchange device according to the indoor air temperature and the area temperature.

[0089] In this embodiment, preset values ​​can be set for the indoor air temperature and the zone temperature, respectively. The operation of the convection heat exchanger is controlled based on the indoor air temperature, the zone temperature, and the preset values ​​corresponding to the indoor air temperature and the zone temperature. These preset values ​​enable intelligent and automatic control of the operating status of the convection heat exchanger.

[0090] A mapping relationship between indoor air temperature, zone temperature, and the operating status of convective heat exchangers can be established in advance. Based on this mapping relationship, the operating status of the convective heat exchangers can be determined, and their operation can be controlled accordingly. The mapping relationship allows for the rapid determination of the operating status of convective heat exchangers and the implementation of appropriate controls.

[0091] The rate of change of indoor air temperature can be determined based on the indoor air temperature, and then the operation of the convection heat exchange equipment can be controlled based on the rate of change of indoor air temperature and the zone temperature. By using the rate of change of indoor air temperature, the changes in indoor air temperature can be clearly known, and the operating status of the convection heat exchange equipment can be controlled, which can balance the changes in indoor air temperature and improve indoor comfort.

[0092] In this embodiment, the operating states of the convection heat exchanger include on-heating, off-state, on-heating, and lowered fan. The following situations exist:

[0093] First, control the radiant terminal equipment to operate in heating mode, while shutting down the convection heat exchanger. Then, based on the indoor air temperature and zone temperature, activate the convection heat exchanger. This method is suitable for situations where radiant terminal equipment heats up slowly, while convection heat exchangers heat up quickly. When the heat generated by the radiant terminal equipment is insufficient, the convection heat exchanger can be activated to rapidly raise the indoor temperature, preventing excessively cold indoor spaces and improving comfort.

[0094] Secondly, the radiant terminal equipment is initially controlled to operate in heating mode, while the convection heat exchange equipment is shut down. The convection heat exchange equipment is kept off based on the indoor air temperature and zone temperature. This approach is suitable for scenarios where the heat generated by the radiant terminal equipment meets the demand, allowing for indoor space heating solely through the radiant terminal equipment, thus improving indoor comfort and energy efficiency.

[0095] Third, the system controls the heating mode of the radiant terminal equipment while the convection heat exchange equipment is turned on for heating. The system lowers the fan speed of the convection heat exchange equipment based on the indoor air temperature and zone temperature. This is applicable when both radiant terminal equipment and convection heat exchange equipment are operating for heating. If the convection heat exchange equipment is immediately shut off when the heat demand is met, the indoor temperature will drop rapidly. This addresses the scenario where the convection heat exchange equipment operates for too short a time, resulting in insufficient heating from the radiant terminal equipment and an excessively cold indoor environment. Conversely, it avoids the situation where the convection heat exchange equipment operates for too long, leading to overheating. By lowering the heating fan speed, the system improves indoor comfort.

[0096] Fourth, both radiant terminal devices and convection heat exchangers are controlled to operate in heating mode. The convection heat exchangers are kept running based on indoor air temperature and zone temperature. This is applicable to scenarios where, when both radiant terminal devices and convection heat exchangers are running, shutting down the convection heat exchangers would cause a rapid drop in indoor temperature if the heating demand is not met, indicating insufficient heating from the radiant terminal devices. By keeping the convection heat exchangers running, the comfort of the indoor space is improved.

[0097] In this embodiment, when the convection heat exchanger operates in heating mode, the refrigerant discharged from the compressor flows sequentially through the second heat exchanger, the convection heat exchanger, the throttling device, and the first heat exchanger before returning to the compressor. Both the second and convection heat exchangers 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 loop 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 convection heat exchanger. The convection heat exchanger in the indoor space requiring heating activates its heating function, releasing heat into the space it is in, thereby achieving a heating effect.

[0098] This embodiment provides a control method for an environmental control system. After the radiant terminal equipment is turned on for heating, the operation of the convection heat exchange equipment is controlled based on the indoor air temperature and the area temperature of the area where the radiant terminal equipment is installed. The indoor air temperature and the area temperature can accurately reflect the heating status of the radiant terminal equipment. Therefore, this control method can match the heating capacity of the convection heat exchange equipment with the heating status of the radiant terminal equipment. The two systems no longer work independently, but their heating capacity is coordinated to avoid overheating or overcooling indoors, thereby improving indoor comfort.

[0099] In one feasible implementation, controlling the operation of the convection heat exchanger based on the indoor air temperature and the area temperature includes: when the indoor air temperature is less than or equal to a set temperature and the area temperature is less than or equal to a first preset temperature, controlling the convection heat exchanger to turn on heating.

[0100] In this embodiment, the set temperature can be a pre-set fixed temperature, such as the maximum temperature, or it can be a temperature determined based on the actual operation of the environmental control system. For example, the set temperature can be determined based on the running time of the radiant terminal devices currently operating in heating mode and / or the ratio of the number of radiant terminal devices currently operating in heating mode to the total number of radiant 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 area is large or there are many people, a lower set temperature may be needed to achieve better cooling or heating effects. Alternatively, the set temperature can be determined based on the temperature difference between the indoor air temperature and the current outdoor air temperature. The larger the temperature difference, the better the cooling effect. Excessive temperature difference may cause discomfort; determining the set temperature based on the indoor-outdoor temperature difference can improve indoor comfort. Alternatively, the set temperature can be determined based on energy efficiency and energy saving.

[0101] The first preset temperature can be a fixed temperature set in advance, such as a lower limit value of the regional temperature. In this embodiment, the lower limit value of the regional temperature ranges from [20 to 25]℃. Alternatively, the first preset temperature can also be a temperature determined based on the actual operation of the environmental control system. For example, the first preset temperature can be determined based on the running time of the radiant terminal equipment in the current heating mode and / or the ratio of the number of radiant terminal equipment in the current heating mode to the total number of radiant terminal equipment.

[0102] In this embodiment, when the indoor air temperature is less than or equal to the set temperature and the area temperature is less than or equal to the first preset temperature, it indicates that the heat from the radiant terminal device is insufficient to raise the floor heating layer temperature to the height required to maintain the set temperature, or the refrigerant temperature after heating by the gas equipment is too low to maintain the indoor temperature. In this case, the convection heat exchange device is turned on to heat the room, and the forced convection between the ducted air conditioner and the indoor air is used to quickly raise the indoor air temperature, thereby avoiding the indoor space from becoming too cold and improving indoor comfort.

[0103] In another feasible implementation, controlling the operation of the convection heat exchanger based on the indoor air temperature and the area temperature includes: keeping the convection heat exchanger off when the indoor air temperature is greater than the set temperature.

[0104] In this embodiment, by means of the above method, when the indoor air temperature is greater than the set temperature, it means that the heat from the radiant terminal device can raise the temperature of the underfloor heating layer to a height sufficient to maintain the set temperature, or the temperature of the refrigerant after heating by the gas equipment is sufficient to maintain the indoor temperature. Therefore, only the radiant terminal device needs to be used for heating, without the need to turn on the convection heat exchanger. This avoids the situation of overheating and energy consumption caused by simultaneously turning on the radiant terminal device and the convection heat exchanger. It not only improves indoor comfort but also reduces energy consumption, achieving the effect of energy saving.

[0105] In another feasible implementation, controlling the operation of the convection heat exchanger based on the indoor air temperature and the area temperature includes: keeping the convection heat exchanger off when the area temperature is greater than the first preset temperature.

[0106] In this embodiment, by means of the above method, when the area temperature is greater than the first preset temperature, it means that the heat from the radiant terminal device can raise the temperature of the underfloor heating layer to a height that can be maintained for the set temperature, or the temperature of the refrigerant after heating by the gas equipment is sufficient to maintain the indoor temperature. Therefore, only the radiant terminal device needs to be used for heating, and there is no need to turn on the convection heat exchanger. This can avoid the situation of indoor overheating and energy consumption caused by turning on the radiant terminal device and the convection heat exchanger simultaneously. It can not only improve indoor comfort, but also reduce energy consumption and achieve the effect of energy saving.

[0107] In another feasible implementation, since the convection heat exchanger may start heating at the same time as the auxiliary terminal equipment after the convection heat exchanger starts heating, resulting in indoor overheating, the indoor air temperature and zone temperature are monitored in real time after the convection heat exchanger starts heating, and the operation of the convection heat exchanger is controlled according to the indoor air temperature and zone temperature.

[0108] In this embodiment, controlling the operation of the convection heat exchanger based on the indoor air temperature and the zone temperature includes: when the indoor air temperature is higher than the set temperature for a duration of a first preset duration or the zone temperature is lower than the first preset temperature for a duration of a second preset duration, controlling the convection heat exchanger to shut down or lower its damper. The first and second preset durations can be fixed pre-set durations, or they can be durations determined based on the actual operation of the environmental control system. For example, the first preset duration can be determined based on the rate of change of the indoor air temperature, and the second preset duration can be determined based on the rate of change of the zone temperature. It is understood that the greater the rate of change of the indoor air temperature, the shorter the first preset duration; and the greater the rate of change of the zone temperature, the shorter the second preset duration.

[0109] Furthermore, in one embodiment, after controlling the convection heat exchanger to start heating when the indoor air temperature is less than or equal to the set temperature and the area temperature is less than or equal to the first preset temperature, the method further includes: when the indoor air temperature is greater than the set temperature, controlling the convection heat exchanger to operate according to the area temperature.

[0110] In this embodiment, controlling the operation of the convection heat exchanger includes at least one of the following: controlling the convection heat exchanger to shut down, and lowering the windshield of the convection heat exchanger.

[0111] In this embodiment, the convection heat exchanger is controlled to shut down or lower its damper based on the area temperature and a second preset temperature. Alternatively, the convection heat exchanger is controlled to shut down or lower its damper based on the rate of temperature change of the area temperature.

[0112] In this embodiment, by controlling the convection heat exchanger to start heating in the manner described above, when the indoor air temperature is higher than the set temperature, the convection heat exchanger is controlled to shut down according to the zone temperature to avoid overheating indoors. Alternatively, the convection heat exchanger can be controlled to lower the fan baffle according to the zone temperature to avoid insufficient zone temperature. If the convection heat exchanger is shut down, the indoor air temperature will drop rapidly, causing poor comfort. This improves indoor comfort.

[0113] In one embodiment, when the area temperature is greater than or equal to a second preset temperature, the convection heat exchanger is shut down; when the area temperature is less than the second preset temperature, the damper of the convection heat exchanger is lowered. The second preset temperature is greater than the first preset temperature.

[0114] The second preset temperature is greater than the first preset temperature. The second preset temperature can be a pre-set fixed temperature, such as a regional temperature upper limit value. In this embodiment, the regional temperature upper limit value ranges from [25 to 35]℃. Alternatively, the second preset temperature can also be a temperature determined based on the actual operation of the environmental control system. For example, the second preset temperature can be determined based on the running time of the radiant terminal devices in the current heating mode and / or the ratio of the number of radiant terminal devices in the current heating mode to the total number of radiant terminal devices.

[0115] In this embodiment, using the above method, when the indoor air temperature is greater than the set temperature and the zone temperature is greater than the second preset temperature, it indicates that the zone temperature has reached the upper limit of the zone temperature. At this time, the zone temperature is sufficient, and controlling the convective heat exchanger to shut down can save energy. When the indoor air temperature is greater than the set temperature and the zone temperature is less than the second preset temperature, it indicates that the zone temperature has not reached the upper limit of the zone temperature. If the convective heat exchanger is shut down at this time, the indoor air temperature will drop rapidly because the zone temperature is still insufficient, affecting indoor comfort. Therefore, by lowering the heating damper of the convective heat exchanger, the indoor air temperature is maintained near the preset temperature, improving indoor comfort.

[0116] In one embodiment, when the duration for which the area temperature is greater than or equal to the second preset temperature reaches a preset duration, the convection heat exchanger is controlled to shut down; when the duration for which the area temperature is less than the second preset temperature reaches a preset duration, the windshield of the convection heat exchanger is lowered, so as to avoid the control error of the convection heat exchanger caused by the judgment of the area temperature at a single time and improve the control accuracy of the convection heat exchanger.

[0117] Furthermore, in one embodiment, after the step of controlling the convection heat exchanger to start heating when the indoor air temperature is less than or equal to the set temperature and the area temperature is less than or equal to the first preset temperature, the method further includes: when the indoor air temperature is less than the set temperature, controlling the operation of the convection heat exchanger according to the area temperature, the indoor air temperature, and the minimum comfort temperature.

[0118] The minimum preset temperature is lower than the first preset temperature. The minimum comfortable temperature can be a pre-set fixed temperature. In this embodiment, the minimum comfortable temperature ranges from [18 to 20]℃. Alternatively, the minimum comfortable temperature can also be a temperature determined based on the actual operation of the environmental control system. For example, it can be determined based on the running time of the radiant terminal devices in the current heating mode and / or the ratio of the number of radiant terminal devices in the current heating mode to the total number of radiant terminal devices. Or, it can be determined based on the size of the current indoor space and / or the number of people in the indoor space.

[0119] In this embodiment, by means of the above method, after the convection heat exchanger is turned on for heating, if the indoor air temperature is lower than the set temperature, it indicates that the current indoor air temperature is too low. The operation of the convection heat exchanger can be controlled according to the area temperature, the indoor air temperature and the minimum comfort temperature, so that when the indoor air temperature is too cold, the operation of the convection heat exchanger is controlled to regulate the indoor air temperature and improve indoor comfort.

[0120] In one embodiment, the operation of the convection device is controlled based on a comparison between the indoor air temperature and the minimum comfortable temperature and / or a comparison between the area temperature and a second preset temperature. Controlling the operation of the convection heat exchange device includes at least one of the following: controlling the convection heat exchange device to shut down; or controlling the convection heat exchange device to remain on for heating; or controlling the convection heat exchange device to raise its heating damper.

[0121] In one embodiment, when the indoor air temperature is greater than or equal to the minimum comfortable temperature and the zone temperature is greater than or equal to the second preset temperature, the convection heat exchange device is controlled to shut down.

[0122] In this embodiment, by means of the above method, when the indoor air temperature is greater than or equal to the minimum comfortable temperature and the area temperature is greater than or equal to the second preset temperature, it means that the indoor air temperature has reached the comfortable range and the area temperature has also met the standard. It is possible to gradually increase the indoor air temperature from the minimum comfortable temperature to the set temperature. At this time, the convection heat exchange equipment can be controlled to be turned off to prevent the problem of the indoor air temperature being too hot due to the convection heat exchange equipment being turned on for too short a heating time, thereby improving indoor comfort.

[0123] In one embodiment, when the indoor air temperature is lower than the minimum comfortable temperature or the area temperature is lower than the second preset temperature, the convection heat exchanger is kept on for heating or the windshield of the convection heat exchanger is raised.

[0124] In this embodiment, when the indoor air temperature is lower than the minimum comfortable temperature or the zone temperature is lower than the second preset temperature, it indicates that the indoor air temperature has not reached the comfort zone or the zone temperature has not met the standard, and the indoor air temperature cannot be gradually increased from the minimum comfortable temperature to the set temperature. At this time, if the convection heat exchange equipment is turned off, the indoor air temperature will drop, resulting in the problem of excessively cold indoor air temperature. Therefore, by continuing to keep the convection heat exchange equipment on for heating or raising the fan baffle of the convection heat exchange equipment, the indoor air temperature is increased, thereby improving indoor comfort.

[0125] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, the heating system further includes a temperature sensor disposed on the radiant terminal device, or the heat pump system further includes an infrared sensor disposed on the convective heat exchange device, the temperature sensor or the infrared sensor being used to collect the temperature of the area.

[0126] Temperature sensors can be installed in the installation area of ​​the radiant terminal equipment to collect the regional temperature of the installation area. When temperature sensors are installed in the installation area, the number and location of the sensors can be determined based on the characteristics of the installation area, such as its location, size, and / or shape. Similarly, when multiple temperature sensors are installed, the average temperature of the installation area is determined based on the temperature data collected by each sensor, and this average temperature is used as the regional temperature of the installation area.

[0127] In this embodiment, the regional temperature of the installation area of ​​the radiant terminal equipment can also be obtained through an infrared sensor. This infrared sensor can be installed on a convection heat exchanger, in the installation area, or in other locations within the indoor space. Infrared imaging technology enables the infrared sensor to simultaneously measure the temperature of multiple targets, forming a temperature distribution image. This helps in analyzing the temperature conditions within the indoor space, thereby obtaining the regional temperature of the installation area of ​​the radiant terminal equipment.

[0128] In this embodiment, the area temperature is collected by a temperature sensor located on a radiating terminal device or an infrared sensor located on a convective heat exchange device, in order to meet the requirements for area temperature collection in different scenarios.

[0129] Based on any of the above embodiments, in the third 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. In this regard, the radiant terminal device is located at the bottom of the indoor space, and obtaining the area temperature of the area where the radiant terminal device is installed includes: obtaining the floor temperature of the indoor space, wherein the area temperature includes the floor temperature.

[0130] In this embodiment, radiant terminal devices, such as radiant floor heating, can be laid at the bottom of the indoor space, and the floor temperature of the indoor space can be used as the area temperature.

[0131] In one embodiment, temperature sensors can be installed at different locations on the bottom of the indoor space. The control device acquires temperature data collected by the temperature sensors at different locations on the ground and calculates the average temperature. This average temperature is used as the area temperature to avoid errors in temperature data collected by a single temperature sensor and improve the accuracy of the ground temperature readings. Alternatively, the bottom of the indoor space can be pre-divided into different blocks, and a corresponding temperature sensor can be installed in each block. Taking each block as the center, temperature data collected by the temperature sensors in the current central block and the blocks in the eight adjacent directions of the current central block are acquired. The average value of the temperature data collected by the temperature sensors in these eight directions is calculated and used as the block temperature corresponding to the current central block. Each block can calculate its corresponding block temperature in the above manner. After obtaining the block temperatures of each block, the average value of the block temperatures of each block 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, improve the accuracy of the block temperature corresponding to each block, and thus improve the accuracy of the area temperature.

[0132] In one embodiment, the radiant terminal device can also be installed at the top of the indoor space, and the temperature at the top of the indoor space can be obtained to determine the area temperature of the radiant terminal device installation area.

[0133] In one embodiment, obtaining the regional temperature of the area where the radiant terminal device is installed includes: obtaining the perceived temperature near a human body in the indoor space, wherein the regional temperature includes the perceived temperature.

[0134] The perceived temperature can be obtained through the wired controller of the environmental control system or the temperature sensor on the personal sensor. The personal sensor can use a remote control to measure the ambient temperature around the human body. The remote control will automatically send a signal to the environmental control system at preset intervals to tell the environmental control system what the ambient temperature is around the human body, so as to adjust the operation of the convection heat exchange equipment and thus improve indoor comfort.

[0135] In this embodiment, by acquiring the floor temperature of the indoor space as the area temperature of the radiant terminal device installation area, the above-described method allows for the determination of temperature distribution. With this setup, in heating mode, for convection heat exchangers, since their air outlets are typically located at a higher position in the indoor space, hot air primarily affects the upper levels. This design can, in some cases, lead to temperature stratification within the indoor air, with higher temperatures in the upper levels and lower temperatures near the floor. Consequently, the temperature felt by the human body primarily originates from the upper part of the body. In contrast, radiant terminal devices, by laying pipes at the bottom of the indoor space, conduct heat generated by hot water or electric heating elements to the floor. Compared to the heating method of convection heat exchangers, this method allows for the even distribution of heat throughout the room via floor radiation. This radiant 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 and improves the comfort of occupants.
