[0039] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0041] 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.

[0042] Common heating systems typically adjust the temperature by activating the indoor unit based on user settings. However, this approach presents several problems: rapid temperature adjustment by the indoor unit leads to frequent on / off cycles, reduced airflow comfort, and temperature stratification causing higher return air temperatures. This results in poor system condensation heat exchange, and consequently, prolonged high-pressure operation of the multi-split refrigeration system, leading to unreliable heat pump system performance and energy inefficiencies.

[0043] Therefore, based on the shortcomings of the above heating control schemes, the control of the environmental conditioning system proposed in this application is proposed. The main solution of the embodiment of this application is: when the indoor unit is in poor operating condition, it is switched to radiant terminal heating by judging from the temperature information, thereby improving the heating efficiency of each heat exchange device in the indoor space and the operating reliability of the heat pump system.

[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 a device capable of performing the above functions, such as a control device for an environmental control system. The following description uses a control device for an environmental control system as an example to illustrate this embodiment and the subsequent embodiments.

[0045] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0046] Reference Figure 1 This application provides a control method for an environmental control system, which includes a heat pump system and a heating system. The heat pump system includes an indoor unit, and the heating system includes radiant terminal equipment. The indoor unit and the radiant terminal equipment are both located in the same indoor space. The control method for the environmental control system includes:

[0047] Step S10: When both the indoor unit and the radiant terminal device are in heating mode, acquire the temperature information of the indoor space;

[0048] In this embodiment, refer to Figure 2 , Figure 2 This is a connection diagram of the environmental control system of this application. The environmental control system includes a heat pump system and a heating system. The heat pump system includes an indoor unit (multi-split indoor unit 410 in the figure), and the heating system includes radiant terminal equipment. Both the indoor unit and the radiant terminal equipment are located in the indoor space.

[0049] In this embodiment, the heat pump system includes at least one multi-split indoor unit 410, which includes an indoor heat exchanger and a corresponding indoor fan. Different multi-split indoor units 410 can be installed in different indoor spaces. Each multi-split indoor unit 410 can be associated with at least one underfloor heating system 300 (i.e., a radiant terminal device). The multi-split indoor unit 410 and its associated underfloor heating system 300 are located in the same indoor space. It is worth noting that each multi-split indoor unit 410 has its own corresponding wired controller 420.

[0050] The heat pump system may include a refrigerant circulation loop, with the multi-split indoor unit 410 located within it. The refrigerant circulation loop is filled with refrigerant (e.g., Freon). The heating system may also include a secondary refrigerant circulation loop, with radiant terminal equipment located within it. The secondary refrigerant circulation loop is filled with secondary refrigerant, which can flow within it. In this embodiment, the secondary refrigerant is water. In other embodiments, the secondary refrigerant may be an aqueous solution of sodium chloride or calcium chloride, or an aqueous solution of organic compounds such as ethylene glycol or glycerol, etc. The refrigerant circulation direction in the refrigerant circulation loop is as follows: During non-defrosting operation, multi-split outdoor unit → multi-split indoor unit → multi-split outdoor unit; during defrosting, the initial defrosting cycle is: compressor → multi-split outdoor unit → throttling mechanism → multi-split indoor unit → compressor. The refrigerant circulation loop is as follows: gas equipment → manifold → terminal / underfloor heating → manifold → gas equipment; or, gas equipment → coupling tank → manifold → terminal / underfloor heating → manifold → coupling tank → gas equipment.

[0051] In this embodiment, the environmental control system further includes a hydraulic unit, which is used to allow the refrigerant to be heated after flowing through the hydraulic unit when the system is in an exothermic state, and to allow the refrigerant to be cooled after flowing through the hydraulic unit when the system is in an endothermic state.

[0052] The function of indoor terminal equipment is to regulate the indoor environment by utilizing the cooling or heating output of the flowing refrigerant. Indoor terminal equipment includes convective heat exchange devices (such as fan coil units) or radiant terminal devices (such as radiators, underfloor heating, etc.). Convective heat exchange devices include a heat exchanger and a corresponding 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. The types of indoor terminal devices in different indoor spaces can be the same or different. When there is more than one indoor terminal device, each indoor space can be equipped with one or more types of indoor terminal devices. Alternatively, when there is more than one indoor terminal device, the more than one indoor terminal device can be connected in parallel. For example, the environmental control system is configured to regulate at least two indoor spaces, each equipped with a radiant terminal device, or each indoor space equipped with both a convective heat exchange device and a radiant terminal device, or each indoor space equipped with only a convective heat exchange device. It is worth noting that the environmental control system also includes a diversity controller 510, a water manifold 520, and a coupler 530, which are used to control the flow of refrigerant in the refrigerant circulation loop.

[0053] The environmental control system may also include a gas appliance 200, which heats the flowing refrigerant by burning gas. The gas appliance 200 may be a gas water heater or other gas-fired equipment.

[0054] In one embodiment, when the indoor unit is in heating mode, the indoor space temperature information is acquired, and the indoor unit is then controlled to stop heating based on this temperature information. The indoor unit being in heating mode means that the indoor unit is operating in heating mode, without limiting the operation of other devices; that is, other devices, such as underfloor heating, can be in heating or off state. It is worth noting that the indoor unit being in heating mode can be controlled using different control methods, such as controlling the indoor unit to heat at different power levels and fan speeds. Temperature information refers to various temperatures within the indoor space, including at least ambient temperature and return air temperature. Ambient temperature represents the temperature of the surrounding environment. Due to temperature stratification in the environment where the heat pump system is located, ambient temperature better reflects the overall temperature of the environment. It can be obtained from multiple temperature sensors installed in the environment, such as determining the average value of temperature data collected from sensors at different locations. Therefore, the indoor unit can be controlled to stop heating based at least on the ambient temperature and return air temperature, thus ensuring that the refrigeration system pressure inside the indoor unit does not become excessive due to temperature stratification, thereby improving the operational reliability of the heat pump system. This also avoids the problem of high heating costs caused by the indoor unit repeatedly turning on and off due to temperature variations.

[0055] Step S20: When the temperature information meets the preset conditions, control the indoor unit to stop heating and control the heating system to keep the radiant terminal equipment in heating state. The preset conditions indicate that the indoor unit is not operating properly.

[0056] In this embodiment, after confirming that the temperature information is met, the indoor unit is controlled to stop heating based on the temperature information, and the heating system is controlled to keep the radiant terminal devices in a heating state. The preset condition indicates poor operating conditions of the indoor unit, which involves determining the relationship between the return air temperature and ambient temperature in the temperature information and the set judgment values, and then determining whether the indoor unit's heating needs to be shut down based on this relationship. Controlling the heating system to keep the radiant terminal devices in a heating state can be achieved by directly turning on the radiant terminal devices, reducing the heating capacity, increasing the heating capacity, or maintaining the heating capacity. The control methods can include controlling the output power and refrigerant flow rate of the radiant terminal devices, or controlling the output power and heating temperature of the heating system. Therefore, controlling the indoor unit's heating module and the heating system based on the return air temperature and ambient temperature to control the radiant terminal devices ensures the stability of the indoor unit's operation. Furthermore, combining the operation of the heating system with the control of the radiant terminal devices ensures the energy-saving effect of the indoor unit's operation.

[0057] In one embodiment, the method of controlling the indoor unit to stop heating based on temperature information can be as follows: if the return air temperature in the temperature information is less than B1 and the ambient temperature in the temperature information is less than C (set room temperature), then the indoor unit is controlled to stop heating, and the heating system is controlled to reduce heat exchange to allow the radiant terminal equipment to supply energy; if the return air temperature in the temperature information is less than B2 and the ambient temperature in the temperature information is less than C (set room temperature), then the indoor unit is controlled to stop heating, and the heating system is controlled to increase heat exchange to allow the radiant terminal equipment to supply energy. The heating system may include gas equipment. Increasing heat exchange in the gas equipment involves increasing the gas equipment output, such as opening the gas proportional valve, increasing the number of burner ignitions, or increasing air circulation. Decreasing heat exchange in the gas equipment involves reducing the gas equipment output, such as reducing the gas proportional valve, reducing the number of burner ignitions, or reducing air circulation. In this case, the outdoor unit can also be controlled to reduce or increase heat exchange, ultimately resulting in a change in the heating effect of the radiant terminal equipment. Other control methods are also possible and are not limited here.

[0058] In this embodiment, a control method for an environmental conditioning system is provided. The environmental conditioning system includes a heat pump system and a heating system. The heat pump system includes an indoor unit, and the heating system includes radiant terminal devices. The indoor unit and the radiant terminal devices are both located in the same indoor space. In this scheme, the temperature information of the indoor space when the indoor unit is in heating mode can accurately reflect the operating condition of the indoor unit. Therefore, when the temperature information determines that the indoor unit is not operating well, the system switches to radiant terminal heating, thereby improving the heating efficiency of each heat exchange device in the indoor space and the operational reliability of the heat pump system.

[0059] Further, based on the first embodiment of this application, a second embodiment of the control method for the environmental conditioning system of this application is proposed. In this embodiment, in step S20 above, the indoor unit includes an indoor heat exchanger and an indoor fan. Under the drive of the indoor fan, indoor air can exchange heat with the indoor heat exchanger. The temperature information includes the return air temperature of the indoor unit, which is used to characterize the air temperature at the return air inlet of the indoor unit in the indoor space. The temperature information also includes the ambient temperature, which is used to characterize the air temperature at the radiant terminal in the indoor space. Before the step of controlling the indoor unit to stop heating and controlling the heating system to operate so that the radiant terminal equipment is in a heating state, the method includes:

[0060] Step S21: If the ambient temperature is less than or equal to the first preset ambient temperature and the return air temperature is greater than or equal to the first preset return air temperature, determine that the preset conditions are met; and / or,

[0061] Step S22: When the ambient temperature is less than or equal to the first preset ambient temperature and the return air temperature is less than the first preset return air temperature, determine whether the preset conditions are met based on the return air temperature, ambient temperature and the status of the equipment in the indoor space. The equipment status includes whether there are any devices other than the indoor unit in heating mode.

[0062] In this embodiment, before the indoor unit stops heating, control can be performed based on the return air temperature of the indoor unit and the ambient temperature outside the indoor unit in the temperature information. The indoor unit can be installed at a height greater than or equal to a first preset height in the indoor space. The indoor unit includes an indoor heat exchanger and an indoor fan. Driven by the indoor fan, indoor air can exchange heat with the indoor heat exchanger. The temperature information includes the return air temperature of the indoor unit, which characterizes the air temperature at the return air vent of the indoor unit in the indoor space. The radiant terminal device can be installed at a height less than or equal to a second preset height in the indoor space, which is less than the first preset height. The temperature information also includes the ambient temperature, which characterizes the air temperature in the indoor space within a range less than or equal to the second preset height. This ensures the accuracy of the collected temperature. It is worth noting that the radiant terminal device and the indoor unit can also have other installation positions, which are not limited here. In this case, the indoor unit uses forced convection heat exchange, with heat exchange achieved by airflow from the fan duct. The radiant terminal device has a certain heat storage capacity or is made of metal, and its heat exchange is much slower than that of the air conditioner's indoor unit. Therefore, when the ambient temperature is less than or equal to the first preset ambient temperature and the return air temperature is greater than or equal to the first preset return air temperature, the preset conditions are met. In this case, to ensure the indoor unit's temperature stability, the indoor unit needs to be shut down, while simultaneously maintaining the heating system so that the radiant terminal devices are in heating mode. The radiant terminal devices being in heating mode can be in a state of increased heating, decreased heating, or constant heating. Conversely, when the ambient temperature is less than or equal to the first preset ambient temperature and the return air temperature is less than the first preset return air temperature, it is determined that to ensure the stability of the indoor unit's operation, further monitoring of the indoor unit's operation is necessary. Based on the return air temperature, ambient temperature, and the status of the equipment in the indoor space, it is determined whether the preset conditions are met. The equipment status includes whether any equipment other than the indoor unit is in heating mode, or whether any terminal devices other than the indoor unit are in heating mode (i.e., equipment other than the indoor unit includes both the equipment and the terminal devices), rather than blindly and continuously turning on the indoor unit for heating, thus ensuring the accuracy of control. Among them, "device status" refers to the status of the indoor unit, such as the operating temperature and the number of units turned on. "First preset ambient temperature" refers to the ambient temperature set by the user or a system-defined ambient temperature. The ambient temperature is based on the temperature value collected by sensors set in the indoor environment. "Return air temperature" refers to the return air temperature of the indoor unit. "First preset return air temperature" is a user-defined trigger temperature threshold, such as "first preset return air temperature T1yb∈[26,36]℃", which can be set to 32℃ by default. It is worth noting that when the ambient temperature is higher than the first preset ambient temperature, it is determined that there is no energy demand, meaning that the indoor unit does not need to be turned on. Therefore, the indoor unit can be directly turned off or its heating output can be reduced, thereby reducing the energy consumption of the indoor unit and continuing to perform operations based on temperature information.If the indoor unit is in a closed state, the system will directly determine whether there is a need to turn on the indoor unit and continue executing the control process of this embodiment when the ambient temperature is less than or equal to the first preset ambient temperature. Otherwise, the system will continuously determine whether to turn on the indoor unit. It is worth noting that the conditions for turning on the indoor unit can also be set to other conditions, such as return air temperature, outdoor temperature, and refrigerant temperature, and then the control method of this application will be executed after the indoor unit is controlled to operate in heating mode.

[0063] In one embodiment, reference is made to Figure 3 , Figure 3This is a flowchart illustrating the control method of the environmental control system in this application. The multi-split air conditioner and gas equipment are connected in a system configuration with communication capabilities: the room-mounted controller is bound to the manifold valve (manifold), and communicates normally with the outdoor unit (multi-split outdoor unit) and the gas equipment (i.e., the wall-mounted boiler in the diagram; hereinafter, the description will focus on the gas equipment). Under normal communication, relevant functions are displayed and the system is in standby mode, such as rapid heating, low-temperature supplemental heating, intelligent supplemental heating, and defrosting supplemental heating. Conversely, if normal communication fails, the linked functions are displayed or grayed out. After the linked functions are activated, the indoor unit and its corresponding room (which can be a room or other environment) underfloor heating are activated according to user settings or functional conditions. When the indoor unit is in heating mode, the system first determines whether the room where the indoor unit is located has energy demand (whether the temperature has been reached, i.e., whether the temperature has been reached by comparing the first preset ambient temperature with the ambient temperature). If the temperature is reached, the indoor unit is controlled to shut off heating. Based on other conditions, such as ambient temperature, return air temperature, outdoor temperature, and refrigerant temperature, the system continues to execute the control process of this embodiment when it is determined that the indoor unit is in heating mode. Conversely, if the temperature has not been reached (when the first preset ambient temperature is greater than or equal to the ambient temperature), the system also needs to determine the relationship between the indoor unit return air temperature T1 and the first preset return air temperature T1yb, and then execute subsequent control based on this relationship. If T1 < T1yb, it is determined that the user's heating demand has not been met, and the indoor unit can continue to provide heating. A further assessment will be made when the floor heating in the room corresponding to the indoor unit is turned on or the second heat source (gas equipment or outdoor unit refrigerant heating) of the outdoor unit supplies heat to the room. In other words, the floor heating in the room can be turned on or the second heat source of the outdoor unit can be increased or decreased, and subsequent control measures can be implemented. However, if T1 ≥ T1yb, the indoor unit is operating poorly and needs to stop heating. This will determine that the indoor unit is forced to stop (to reach the required temperature), shut down, or operate with ventilation. The floor heating in the room corresponding to the indoor unit will be turned on, and the gas equipment (second heat source) will be turned on to restore normal heating capacity. This means the indoor unit will be turned off or ventilation will be activated. At this time, the gas equipment will be turned on or its heating capacity will be increased or decreased. Furthermore, the heating control of the indoor unit can be based on the return air temperature and ambient temperature, as well as the operation of the heating system and the heating of the radiant terminals. This avoids the indoor unit from operating poorly due to continuous operation, thus improving the stability of the indoor unit. At the same time, combined with the operation of the heating system and the heating control of the radiant terminals, the energy consumption caused by repeated on / off switching of the indoor unit can be avoided.

[0064] Furthermore, the steps for determining whether the preset conditions are met based on the return air temperature, ambient temperature, and the status of equipment in the indoor space include:

[0065] Step S221: When there is a device other than the indoor unit in heating mode, the return air temperature is greater than or equal to the second preset return air temperature, and the ambient temperature meets the first temperature condition, it is determined that the preset condition is met, wherein the second preset return air temperature is less than the first preset return air temperature.

[0066] The first temperature condition includes an ambient temperature less than or equal to a second preset ambient temperature, or an ambient temperature less than or equal to a second preset ambient temperature and a duration greater than or equal to a first preset duration, wherein the second preset ambient temperature is greater than or equal to the first preset ambient temperature.

[0067] In this embodiment, when determining whether the preset conditions are met based on the return air temperature, ambient temperature, and the status of the equipment in the indoor space, if it is determined that there are devices other than the indoor unit in heating mode, and the return air temperature is less than the second preset return air temperature while the ambient temperature meets the first temperature condition, then it is determined that the indoor unit is at risk of malfunction, and therefore it is determined that the indoor unit needs to be shut down. The second preset return air temperature is greater than or equal to the first preset return air temperature, and the first temperature condition includes either an ambient temperature less than or equal to the second preset ambient temperature, or an ambient temperature less than or equal to the second preset ambient temperature for a duration greater than or equal to the first preset duration. In other words, the first temperature condition requires only one of two conditions to be met: either the ambient temperature is less than or equal to the second preset ambient temperature, or the ambient temperature is less than or equal to the second preset ambient temperature for a duration greater than or equal to the first preset duration. In short, it means that the ambient temperature is either less than or equal to the second preset ambient temperature, or the ambient temperature is greater than the second preset ambient temperature, but the ambient temperature is less than or equal to the second preset ambient temperature for a duration greater than or equal to the first preset duration. If the return air temperature is lower than the second preset return air temperature, or the ambient temperature does not meet the first temperature condition, the indoor unit can be directly shut down without forcibly controlling the radiant terminal equipment and heating system. Then, when the indoor unit is on, the scheme of this embodiment can continue to be executed; alternatively, the scheme of this embodiment can be executed directly. It is worth noting that when no equipment other than the indoor unit is in heating mode, the equipment other than the indoor unit can be automatically turned on to be in heating mode, or the subsequent judgment process can be directly executed. Alternatively, the indoor unit can be directly controlled to remain on until the return air temperature is greater than or equal to the first preset return air temperature.The second preset return air temperature refers to a user-defined temperature value, such as T1ya ∈ [26, 36]℃, which can be set to 32℃ by default. The second preset ambient temperature refers to a user-defined room temperature value, such as T1_Ry ∈ [18, 26]℃, which can be set to 20℃ by default. The first preset duration is the total duration during which the ambient temperature is less than or equal to the second preset ambient temperature, with the first preset duration t1 ∈ [0, 60] min, which can be set to 5 min by default. This allows for the determination of the indoor unit's shutdown status based on the ambient temperature and return air temperature, and by adding a ring... Judging the ambient temperature can determine the heat dissipation performance of the indoor unit. If the indoor unit's heat dissipation is poor (or due to improper installation, short circuit of supply and return air, or clogged filter, etc.) based on the ambient temperature (if the ambient temperature is less than or equal to the second preset ambient temperature, or the duration of the ambient temperature being less than or equal to the second preset ambient temperature is greater than or equal to the first preset duration), it is difficult to raise the room temperature even after long-term operation. Running this indoor unit for a long time will not achieve the desired effect. The indoor unit's heating function in this room should be turned off and switched to underfloor heating (radiator) of the gas equipment to solve the problems of energy saving and discomfort caused by running this indoor unit for a long time.

[0068] In one embodiment, in addition to the above judgment method, a judgment is also made based on the temperature difference between the ambient temperature and the return air temperature, and then based on the relationship between the temperature difference and the temperature difference threshold. The temperature difference is the difference between the ambient temperature and the return air temperature, and the temperature difference threshold is a user-defined temperature value, Δ∈[4~20]℃, which can be set to 10℃ by default. If the difference is 10℃, it is determined that the temperature difference threshold is exceeded. If the temperature difference is greater than the temperature difference threshold, the preset condition is determined to be met; conversely, if the temperature difference is less than or equal to the temperature difference threshold, the preset condition is determined not to be met. This achieves the determination of the indoor unit's heat dissipation function, solving the problems of energy inefficiency and discomfort caused by long-term operation of the indoor unit. The above judgment process can be directly performed, thus directly determining the indoor unit's heat dissipation function, improving the reliability of high-temperature heating in multi-split systems while also improving the reliability of heating when the indoor unit's operating rate is low.

[0069] In one embodiment, reference is made to Figure 3 When other equipment besides the indoor unit is in heating mode, i.e., when the underfloor heating in the room corresponding to the indoor unit is turned on or the second heat source of the outdoor unit (gas equipment or refrigerant heating of multi-split outdoor units) is supplying heat to the room, by determining that the return air temperature of the indoor unit T1≥T1ya and the ambient temperature T1_Rn≤T1_Ry, and the duration reaches t1, it will be determined that the heat dissipation of the indoor unit is not good. Then it is determined that the indoor unit is forced to shut down (reach the temperature), or shut down or run with ventilation. The underfloor heating in the room corresponding to the indoor unit is turned on, the gas equipment (second heat source) is turned on, and its heating capacity needs to be restored to normal, thereby ensuring the stability of the indoor unit's operation.

[0070] Furthermore, based on the first and / or second embodiments of this application described above, a third embodiment of the control method for the environmental control system of this application is proposed. In this embodiment, before step S20, where the temperature information includes the return air temperature, the indoor unit is controlled to stop heating, and the heating system is controlled to operate so that the radiant terminal equipment is in a heating state, the method further includes:

[0071] Step S23: If the return air temperature is greater than or equal to the third preset return air temperature and the duration is greater than or equal to the second preset duration, it is determined that the preset conditions are met.

[0072] In this embodiment, before controlling the indoor unit to stop heating, control can also be based on the return air temperature. This involves collecting the relationship between the current return air temperature of the indoor unit and a third preset return air temperature, and then determining whether to control the indoor unit to stop heating based on this relationship. The heating system is then controlled to keep the radiant terminal equipment in a heating state. The third preset return air temperature is a user-defined temperature threshold, such as [26,36]℃, which can default to 32℃. A second preset duration is also set, t2∈[0,10]min, which can default to 1min. Therefore, judging the heat dissipation function of the indoor unit solely based on the return air temperature can ensure the stability of the indoor unit's operation.

[0073] In one embodiment, reference is made to Figure 3 When the indoor unit's ambient temperature T1 ≥ T1yb and the total duration reaches the second preset duration t2, the indoor unit is determined to be forced to shut down (reach the required temperature), or to operate with ventilation. The floor heating in the corresponding room is turned on, the gas equipment (second heat source) is turned on, and its heating capacity needs to be restored to normal. Otherwise, the indoor unit is controlled to turn on and the control process of this application continues to be executed.

[0074] Furthermore, based on the first, second, and / or third embodiments of this application described above, a fourth embodiment of the control method for the environmental conditioning system of this application is proposed. In this embodiment, the heating system includes a gas appliance and a refrigerant circulation loop, and the radiant terminal is located in the refrigerant circulation loop. After the step of controlling the operation of the heating system to put the radiant terminal device in a heating state, the method includes:

[0075] Step a: Obtain the return air temperature of the indoor unit and the indoor temperature of the indoor space, and determine the target refrigerant temperature of the refrigerant circulation loop based on the return air temperature and the indoor temperature.

[0076] Step b: Control the operation of the gas equipment according to the target refrigerant temperature.

[0077] In this embodiment, the heating system includes gas equipment and a refrigerant circulation loop. Radiant terminals are located in the refrigerant circulation loop. After controlling the heating system to put the radiant terminal equipment into a heating state, the return air temperature of the indoor unit and the indoor temperature of the room can be obtained. Then, a target refrigerant temperature for the refrigerant circulation loop can be determined based on the return air temperature and the indoor temperature, so as to control the operation of the gas equipment based on the target refrigerant temperature. Here, the return air temperature refers to the return air temperature of the indoor unit, and the indoor temperature refers to the temperature of the room where the indoor unit is located. Therefore, the average temperature of the return air temperature and the indoor temperature can be directly used as the target refrigerant temperature. Alternatively, a target refrigerant temperature higher than the average temperature of the return air temperature and the indoor temperature can be used to control the operation of the gas equipment. Other determination methods are also possible, which will not be described in detail here. It can also control the operation of the outdoor unit, thereby altering the heat exchange based on the gas equipment and / or the outdoor unit, and thus changing the heating effect of the radiant terminals. Control modes include controlling the gas equipment to shut down, turning it on, controlling the gas equipment to perform temperature increase control (e.g., opening the gas proportional valve, increasing the number of burner ignitions, increasing air circulation), controlling the gas equipment to perform temperature decrease control (e.g., closing the gas proportional valve, reducing the number of burner ignitions), and controlling the output power of the outdoor unit. This allows for combined heating by the indoor unit and the radiant terminals, ensuring heating comfort.

[0078] In one embodiment, based on the structure of the environmental control system, when the indoor unit or gas equipment is running in conjunction, a high return air temperature (T1) when the indoor unit's heating is on indicates that the room temperature is rising too quickly in a localized area. This means that the operating environment of the environmental control system is not ideal, making it prone to high pressure exceeding the range or prolonged operation in an unfavorable condition, resulting in energy-inefficient indoor unit operation. In this case, it is necessary to shut down the indoor unit or cool the air supply to address the reliability risks of excessive pressure or unfavorable environment in the indoor unit's heating module. This can be achieved by setting a return air temperature (T1) to allow the temperature to recover, and then resuming normal operation once the return air temperature has decreased to a suitable range. If the indoor unit's heating is on for an extended period and the return air temperature (T1_Rn) is consistently high while the ambient temperature (T1_Rn) is low, it indicates poor heat dissipation of the indoor unit (or improper installation, short circuit between supply and return air, or clogged filters, etc.). Even with prolonged operation, the room temperature will be difficult to rise, and running the indoor unit continuously will not achieve the desired effect. In this case, the indoor unit's heating should be shut down and switched to underfloor heating (radiators) from the gas equipment to resolve the energy-inefficient and uncomfortable issues associated with prolonged operation of the indoor unit. It is worth noting that if the indoor heating system is on for a long time and the return air temperature T1 is high while the ambient temperature T1_Rn is low, the judgment can also be made directly based on the return air temperature and the ambient temperature, and will not be limited here.

[0079] In one embodiment, after the step of controlling the indoor unit to stop heating when the temperature information meets the preset conditions and controlling the heating system to operate so that the radiant terminal equipment is in a heating state, the following steps are included:

[0080] Step b: Obtain the return air temperature of the indoor unit;

[0081] Step c: When the return air temperature is lower than the fourth preset return air temperature, control the indoor unit to operate in heating mode.

[0082] In this embodiment, after controlling the indoor unit to stop heating and controlling the heating system to ensure the radiant terminal equipment is in a heating state, in addition to controlling the heating system to ensure the radiant terminal equipment is in a heating state, it also determines how to trigger the indoor unit to start heating. By acquiring the return air temperature of the indoor unit at this time, and then controlling the indoor unit to start heating when the return air temperature is less than the fourth preset return air temperature, the indoor unit will not cause heat dissipation or other operational stability issues, thus ensuring the operational stability of the indoor unit. Here, the fourth preset return air temperature refers to the temperature value set by the user, the fourth preset return air temperature T1yc∈[24,32]℃, which can be 28℃ by default. Therefore, when the return air temperature is greater than or equal to the fourth preset return air temperature, it is determined that the indoor unit needs to be cooled to the required temperature to avoid affecting heat dissipation, and the step of acquiring the return air temperature of the indoor unit will be executed. Conversely, when the return air temperature is less than the preset recovery temperature threshold, it is determined that the indoor unit has been cooled to the required temperature, and the indoor unit will be turned on to start heating. This can reduce the control and heating pressure on the indoor unit, avoid prolonged high-pressure control or repeated on / off cycles, and thus greatly reduce the energy consumption of the indoor unit.

[0083] In one embodiment, reference is made to Figure 3 When T1 ≥ T1yb, it is determined that using the indoor unit for heating would cause a heat dissipation problem, requiring the indoor unit to be stopped. This necessitates either forced shutdown (to reach the required temperature), shutdown, or operation with only ventilation. The corresponding room's underfloor heating and gas-fired heating (second heat source) will then be activated, and their heating capacity needs to return to normal. At this point, the return air temperature T1 under this condition is acquired and compared with the fourth preset return air temperature T1yc. Only when T1 < T1yc will the process of acquiring the return air temperature T1 under this condition be initiated, controlling the indoor unit to start heating, and executing the subsequent control steps. It is worth noting that this allows for an increase in the range of the fourth preset return air temperature to avoid the noise risk associated with frequent on / off cycles of the indoor unit.

[0084] Furthermore, based on the first, second, third, and / or fourth embodiments of this application described above, a fifth embodiment of the control method for the environmental control system of this application is proposed. In this embodiment, the control method for the environmental control system further includes:

[0085] Step d: When the indoor unit is in a stopped heating state and the radiant terminal device is in a heating state, obtain the ambient temperature of the indoor space;

[0086] Step e: When the ambient temperature is less than or equal to the second preset ambient temperature, control the indoor heating system to operate.

[0087] In this embodiment, when the indoor unit is in a stopped heating state and the radiant terminal device is in a heating state, the ambient temperature of the indoor space is acquired. If the ambient temperature is less than or equal to a second preset ambient temperature, the indoor unit is controlled to operate in heating mode. It's worth noting that the above control process can also be executed when the radiant terminal device is not in a heating state; alternatively, the radiant terminal device can be put into heating mode before subsequent control is executed. If the ambient temperature is greater than the second preset ambient temperature, it is determined that the working environment corresponding to the entire system has reached the required temperature, and the step of acquiring the ambient temperature of the indoor space continues. Conversely, if the ambient temperature is less than or equal to the second preset ambient temperature, it is determined that the working environment corresponding to the entire system has not reached the required temperature. Since the indoor unit is off, the indoor unit is controlled to turn on for heating. It's worth noting that the second preset ambient temperature can be equal to or less than the first preset ambient temperature, thus using different thresholds to determine whether the indoor unit is on or off. Therefore, the control of the indoor unit to turn on for heating can be determined based on the ambient temperature and the second preset ambient temperature to achieve joint control and ensure heating comfort.

[0088] In one embodiment, reference is made to Figure 3 When the underfloor heating in the room corresponding to the indoor unit is on, but the indoor unit's heating is not, the system determines whether there is energy demand in the room (whether the temperature has been reached, i.e., the relationship between the ambient temperature and the second preset ambient temperature). If there is no energy demand, the system obtains the ambient temperature of the indoor space; if there is energy demand, the indoor unit's heating is activated. While the indoor unit is heating, the control process of this application continues to execute to achieve joint control, ensuring both heating comfort and cost-effectiveness.

[0089] 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.
