[0061] 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.

[0062] 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.

[0063] The main solution of this application embodiment is: a control method based on an environmental control system, the method comprising controlling the operation of the environmental control system to ensure that both the convective heat exchange device and the radiative terminal device in the target space are in a heat exchange state; under the condition of satisfying a first preset condition, controlling the operation of the environmental control system to stop the convective heat exchange device from exchanging heat and to maintain the heat exchange state of the radiative terminal device; acquiring a first temperature state parameter of the target space; and controlling the environmental control system to adjust the heat exchange capacity of the radiative terminal device and / or the convective heat exchange device according to the first temperature state parameter; wherein, the first preset condition indicates that the heat exchange capacity of the radiative terminal device is sufficient.

[0064] In this embodiment, for ease of description, the environmental control system will be used as the implementing entity for the following description.

[0065] In related technologies, when an indoor space is equipped with both convection terminals (such as ducted air conditioners or fan coil units) and radiant terminals (such as underfloor heating), the heat transfer characteristics of these two types of terminals differ. Convection terminals have a fast heat exchange efficiency, while radiant terminals have a lag in heat exchange efficiency. Currently, heat exchange is generally carried out first through convection terminals, and then switched to radiant terminals after the indoor temperature reaches a certain level. However, this method can easily cause a large change in indoor temperature after the convection terminals stop exchanging heat, affecting indoor comfort.

[0066] This application provides the above-mentioned solution, which uses a convection heat exchanger to regulate the indoor temperature of the target space. During this process, the power supply of the radiant terminal device with lagging heat transfer characteristics in the target space is uninterrupted. When the heat exchange of the system to the target space is high enough, the convection heat exchanger first stops heat exchange, and then the heat exchange of the convection heat exchanger and / or the radiant terminal device is adjusted according to the temperature state parameters of the target space. This can avoid large changes in indoor temperature after the convection terminal stops heat exchange, thereby reducing indoor temperature fluctuations and improving indoor comfort.

[0067] In this embodiment of the invention, reference is made to Figures 1 to 3The environmental control system includes indoor terminal devices 400, which are installed in an indoor space to regulate the air.

[0105] In the seventh temperature control mode, at least one of the following is activated: the heat pump device 200 is in heating mode (the compressor's exhaust port is connected to the second heat exchanger) and the gas device 300 is activated. The fan in the convection heat exchange device 41 is activated, the sub-regulation module corresponding to the radiant terminal device 42 is activated, and the sub-regulation module corresponding to the convection heat exchange device 41 is activated. Both the convection heat exchange device 41 and the radiant terminal device 42 release heat to their respective spaces.

[0106] In the eighth temperature control mode, at least one of the following is activated: the heat pump device 200 operates in heating mode (the compressor's exhaust port is connected to the second heat exchanger) and the gas device 300.

[0107] In the ninth temperature control mode, at least one of the following is activated: the heat pump device 200 operates in heating mode (the compressor's exhaust port is connected to the second heat exchanger and the compressor's return port is connected to the first heat exchanger) and the gas device 300.

[0108] In defrosting mode, the heat pump equipment 200 operates in defrosting mode (the compressor's exhaust port is connected to the first heat exchanger and the compressor's return port is connected to the second heat exchanger). When the fan in the convection heat exchange device 41 is turned on and the corresponding sub-regulation module is turned on, the convection heat exchange device 41 can release heat to its space. When the fan in the convection heat exchange device 41 is turned off and the corresponding sub-regulation module is turned off, the convection heat exchange device 41 can stop heat exchange. When the sub-regulation module corresponding to the radiant terminal device 42 is turned on, the radiant terminal device 42 releases heat to its space. When the sub-regulation module corresponding to the radiant terminal device 42 is turned off, the radiant terminal device 42 stops heat exchange. The heating capacity of the gas equipment 300 is greater than or equal to the cooling capacity released by the second heat exchanger. When at least one of the convection heat exchanger 41 and the radiant terminal device 42 is in a heat release state, the heating capacity of the gas equipment 300 is greater than the cooling capacity released by the second heat exchanger. When both the convection heat exchanger 41 and the radiant terminal device 42 stop heat exchange, the heating capacity of the gas equipment 300 may be greater than or equal to the cooling capacity released by the second heat exchanger.

[0118] The environmental control system provided in this application, employing the control method of the environmental control system in the following embodiments, can solve the technical problem of how to reduce indoor temperature fluctuations and improve indoor comfort. Compared with the prior art, the beneficial effects of the environmental control system provided in this application are the same as those of the control method of the environmental control system provided in the following embodiments, and other technical features of this environmental control system are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0119] 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.

[0120] Based on this, embodiments of this application provide a control method for an environmental control system, referring to... Figure 5 , Figure 5 This is a flowchart illustrating the first embodiment of the control method for the environmental control system of this application.

[0121] In this embodiment, the control method of the environmental control system includes steps S10 to S40:

[0122] Step S10: Control the operation of the environmental control system to ensure that both the convective heat exchange device and the radiative terminal device in the target space are in a heat exchange state;

[0123] The target space is an indoor space with preset functions enabled. When the environmental control system regulates more than one indoor space, the number of target spaces can be one or more, and the preset functions of each indoor space can be turned on or off according to the user's needs in the corresponding space.

[0124] In this embodiment, when the preset function is enabled, the environmental control system is in a supplementary energy mode (e.g., a supplementary heating mode), and step S10 is executed in the supplementary energy mode. The preset function is enabled or disabled in response to user commands. The supplementary energy mode is configured to cooperate between the convective heat exchange device and the radiant terminal device to meet the temperature comfort requirements of the target space.

[0125] The heat exchange state includes either a heating state or a cooling state. In this embodiment, the heat exchange state is a heating state, where both the heat exchanger and the radiant terminal device in the convective heat exchange device are in a heat release state, releasing heat to the target space.

[0126] In this embodiment, when the radiant terminal device is in heat exchange state, the environmental control system can output a prompt message indicating that the preset function is allowed to operate. Subsequently, upon receiving the start command of the preset function, the preset function is activated, and the environmental control system enters the energy replenishment mode. At this time, the radiant terminal device maintains heat exchange and determines whether the heat exchange of the environmental control system is sufficient. If the heat exchange is insufficient, the environmental control system is controlled to operate so that the convective heat exchange device in the target space is in heat exchange state.

[0127] When the convection heat exchanger is in the refrigerant circulation loop, the compressor is on, the throttling device is in a throttling state, and the fan in the convection heat exchanger is on, so the convection heat exchanger is in a heat exchange state; when the fan in the convection heat exchanger is off, the convection heat exchanger stops heat exchange. When the convection heat exchanger stops heat exchange, the compressor can remain on if other indoor spaces outside the target space have temperature regulation needs.

[0128] When the refrigerant circulation loop is in operation, the heat pump and / or gas equipment are turned on, the fan in the convection heat exchanger is turned on, and the corresponding sub-regulation module of the convection heat exchanger is turned on, then the convection heat exchanger is in heat exchange state; when both the heat pump and gas equipment are turned off and / or the fan in the convection heat exchanger is turned off and / or the corresponding sub-regulation module of the convection heat exchanger is turned off, then the convection heat exchanger stops heat exchange.

[0129] When the radiant terminal device is located in the refrigerant circulation loop, the heat pump equipment and / or gas equipment are turned on, and the corresponding sub-regulation module of the radiant terminal device is turned on, so the radiant terminal device is in heat exchange state; when both the heat pump equipment and gas equipment are turned off and / or the corresponding sub-regulation module of the radiant terminal device is turned off, the convective heat exchange device stops heat exchange.

[0130] Step S20: Under the condition of satisfying the first preset condition, control the operation of the environmental conditioning system to stop the heat exchange of the convective heat exchange device and maintain the heat exchange state of the radiative terminal device. The first preset condition means that the heat exchange of the environmental conditioning system in the target space is greater than the preset heat exchange.

[0131] The preset heat exchange rate is used to distinguish whether the total heat exchange rate of the environmental control system in the target space is at a critical value that poses an excessive risk. Here, the temperature of the target space does not reach the user's desired comfort level when the first preset condition is met. The first preset condition may include the required temperature conditions for the indoor temperature parameters of the target space and / or the required duration for the convection heat exchange device to be in heat exchange mode and / or the required duration for the radiant terminal device to be in heat exchange mode, etc. In this embodiment, the heat exchange mode is the heating mode, and the first preset condition includes at least one of the following:

[0132] Condition 1.1: The current temperature of the target space is greater than or equal to the second preset comfortable temperature, or the temperature of the target space is greater than or equal to the second preset comfortable temperature and continues for a second duration;

[0133] Condition 1.2, the duration during which the radiant terminal device is in heat exchange state is greater than or equal to the third duration;

[0134] Condition 1.3: The current temperature of the target space is greater than or equal to the second upper limit temperature of the target space.

[0135] Regarding condition 1.1, the second preset comfort temperature can be a user-set temperature, a system default temperature, or a temperature obtained by the system based on user characteristic analysis of the target space, etc. The second preset comfort temperature can be determined based on the set temperature corresponding to the target space and / or the second upper limit temperature of the target space. The set temperature is the target value that the target space temperature needs to reach to meet the comfort requirements of the target space. In this embodiment, the minimum temperature between the second temperature threshold and the second upper limit temperature is determined as the second preset comfort temperature; wherein, the second temperature threshold is the sum of the fourth preset temperature difference and the set temperature corresponding to the target space. The fourth preset temperature difference can be less than 0, equal to 0, or greater than 0, with a value range of [-5℃, 10℃]. In this embodiment, when the heat exchange state is in heating mode, the second temperature threshold is less than the set temperature. A target space temperature greater than or equal to the second temperature threshold indicates that the target space temperature is close to or has reached or exceeded the set temperature. The second duration can be a pre-set duration or a duration determined based on the actual operation of the system, for example, it can be determined based on the initial temperature of the target space when the convection heat exchanger starts in heat exchange mode and / or the outdoor ambient temperature of the system environment.

[0136] Regarding condition 1.2, the duration here refers to the total time the radiant terminal device maintains in heat exchange mode, which can be obtained by statistically analyzing the duration of operation of the corresponding sub-regulation modules of the radiant terminal device. The third duration is longer than the second duration. The third duration can be a pre-set fixed duration or a duration determined based on the actual operating conditions of the system. For example, the third duration can be determined based on the initial temperature of the target space when the convective heat exchanger starts heat exchange mode and / or the outdoor ambient temperature of the system environment.

[0137] Regarding condition 1.3, the second upper limit temperature is the maximum temperature that the target space can comfortably tolerate when both the radiant terminal device and the convective heat exchange device are in heating mode.

[0138] If the above conditions are met, it can be considered that if the convection heat exchange device and the radiant terminal device are used simultaneously to heat the target space, the indoor temperature of the target space is at risk of being too high and may easily deviate from the user's comfort level.

[0139] In this embodiment, the heat exchange of the convection heat exchange device can be stopped in at least one of the following ways: the sub-regulation module corresponding to the convection heat exchange device is turned off, the fan in the convection heat exchange device is turned off, the compressor in the gas equipment and / or heat pump equipment is turned off, etc.

[0140] When the radiant terminal unit maintains heat exchange, its power supply gas equipment and / or heat pump equipment remain on, and the corresponding sub-regulation module of the radiant terminal unit remains on. After the convective heat exchanger stops heat exchange, the radiant terminal unit can maintain a constant or increase the heat exchange capacity during the heat exchange process.

[0141] Step S30: Obtain the first temperature state parameter of the target space;

[0142] The first temperature status parameter may include at least one of the following: current indoor temperature, indoor temperature change value, temperature change trend, etc.

[0143] During step S30, the convection heat exchange device in the target space remains in a stopped heat exchange state, and the radiation terminal device remains in a heat exchange state. In this embodiment, step S30 is executed if the duration of the stopped heat exchange by the convection heat exchange device after step S20 is greater than or equal to a set duration.

[0144] Step S40: Control the environmental control system to adjust the heat exchange capacity of the radiant terminal device and / or the convective heat exchange device according to the first temperature state parameter.

[0145] The heat exchange adjustment of the radiant terminal device can be achieved through at least one of the following methods: opening or closing the sub-regulation module corresponding to the radiant terminal device, adjusting the heating operation parameters of the gas equipment (e.g., heating power, air-fuel ratio, number of ignited burners, etc.), adjusting the operating parameters of the heat pump equipment (e.g., compressor operating frequency, throttling device opening, fan speed corresponding to the first heat exchanger, etc.), etc.

[0146] The heat exchange capacity of the convection heat exchanger can be adjusted by at least one of the following methods: opening or closing the sub-regulation module corresponding to the convection heat exchanger, adjusting the heating operation parameters of the gas equipment (e.g., heating power, air-fuel ratio, number of ignited burners, etc. at least one), adjusting the operating parameters of the heat pump equipment (e.g., compressor operating frequency, throttling device opening, fan speed corresponding to the first heat exchanger, fan speed corresponding to the second heat exchanger, etc. at least one), etc.

[0147] The environmental control system is controlled according to a first temperature state parameter to maintain the radiant terminal device in a heat exchange state or to stop the radiant terminal device from heat exchange, and / or, according to the first temperature state parameter, the environmental control system is controlled to stop the convective heat exchange device from heat exchange or to resume the convective heat exchange device from heat exchange. Wherein, when the radiant terminal device is maintaining a heat exchange state, the current heat exchange capacity of the radiant terminal device can also be increased, decreased, or maintained according to the first temperature state parameter.

[0148] This embodiment provides a control method for an environmental control system. In the process of adjusting the indoor temperature of the target space using a convection heat exchanger, the power supply of the radiant terminal device with lagging heat transfer characteristics in the target space is uninterrupted. When the heat exchange of the system to the target space is high enough, the convection heat exchanger first stops heat exchange, and then the heat exchange of the convection heat exchanger and / or the radiant terminal device is adjusted according to the temperature state parameters of the target space. This can avoid large changes in indoor temperature after the convection terminal stops heat exchange, thereby reducing indoor temperature fluctuations and improving indoor comfort.

[0149] In other embodiments, the first preset condition may further include the temperature difference between the current temperature of the target space and the set temperature being less than a first set temperature difference threshold.

[0150] In other embodiments, the second preset comfort temperature may also be the average of the second temperature threshold and the second upper limit temperature.

[0151] In one feasible implementation, step S40 includes: when the first temperature state parameter meets the second preset condition, controlling the operation of the environmental conditioning system to keep the convective heat exchange device stopped heating, and controlling whether the environmental conditioning system stops the heat exchange of the radiant terminal device according to the first indoor temperature of the target space; wherein, the second preset condition indicates that the heat exchange of the radiant terminal device to the target space is sufficient.

[0152] When the second preset condition is met, it can be considered that after the convective heat exchanger stops heat exchange, using only the radiant terminal device to heat the target space can meet the comfort requirements of the target space. When the second preset condition is not met, it can be considered that after the convective heat exchanger stops heat exchange, using only the radiant terminal device to heat the target space carries the risk of insufficient heat exchange to meet the comfort requirements of the target space. The moment when the second preset condition is met can be considered the final shut-off moment of the convective heat exchanger, after which only the radiant terminal device can be used to heat the target space.

[0153] In this embodiment, the heat exchange state is a heating state, and the second preset condition includes at least one of the following:

[0154] Condition 2.1: The temperature difference between the minimum temperature in the target space and the current indoor temperature of the target space within a preset time after the convection heat exchange device stops heat exchange is less than or equal to a first preset temperature difference.

[0155] Condition 2.2, the current indoor temperature of the target space is greater than or equal to the first preset comfort temperature, or the current indoor temperature of the target space is greater than or equal to the first preset comfort temperature and continues for a first duration.

[0156] Regarding condition 2.1, after the convection heat exchanger stops heat exchange, the current temperature of the target space is detected at preset time intervals to obtain the first temperatures of at least two target spaces. Within a preset time period during which the convection heat exchanger stops heat exchange, the minimum value of all the obtained first temperatures is determined as the minimum temperature here. If the temperature difference between the minimum temperature and the current indoor temperature of the target space is less than or equal to the first preset temperature difference, it indicates that the temperature fluctuation of the target space is small, and it can be considered that the heat exchange capacity of the radiant terminal device is sufficient after the convection heat exchanger stops heat exchange, and the radiant terminal device can be used alone to heat the target space. If the temperature difference between the minimum temperature and the current indoor temperature of the target space is greater than the first preset temperature difference, it indicates that the temperature fluctuation of the target space is large, and it can be considered that the heat exchange capacity of the radiant terminal device is insufficient after the convection heat exchanger stops heat exchange, and the convection heat exchanger is needed to assist in heat exchange to meet the comfort requirements of the target space.

[0157] Regarding condition 2.2, the first preset comfort temperature can be a user-set temperature, a system default temperature, or a temperature obtained by the system based on user characteristic analysis of the target space, etc. The first preset comfort temperature is greater than or equal to the second preset comfort temperature mentioned above. The second preset comfort temperature can be determined based on the set temperature corresponding to the target space and / or the first upper limit temperature of the target space. The set temperature is the target value that the temperature of the target space needs to reach to meet the comfort requirements of the target space. The second upper limit temperature is the maximum allowable temperature for comfort in the target space when all radiant terminal devices are in heating mode and the convective heat exchange devices are in a stopped heat exchange mode. The first upper limit temperature is greater than the second upper limit temperature mentioned above. In this embodiment, the minimum temperature between the first temperature threshold and the first upper limit temperature of the target space is determined as the first preset comfort temperature; wherein, the first temperature threshold is the sum of the second preset temperature difference and the set temperature corresponding to the target space. The second preset temperature difference is greater than the fourth preset temperature difference mentioned above. The second preset temperature difference can be less than 0, equal to 0, or greater than 0, and its value range is [-5℃, 10℃]. A target space temperature greater than or equal to the first temperature threshold indicates that the temperature rise or fall of the target space is very small, and a target space temperature less than the first temperature threshold indicates that the temperature fall of the target space is significant. The first duration can be a pre-set duration or a duration determined based on the actual operation of the system. For example, the first duration can be determined based on the temperature of the target space when the convection heat exchanger stops heat exchange and / or the outdoor ambient temperature of the system environment.

[0158] After the convection heat exchanger stops heat exchange, the first temperature state parameter meets the second preset condition, indicating that the indoor temperature fluctuates less during the heat exchange process of the radiant terminal device alone, which can meet the comfort requirements of the target space.

[0159] The decision to stop heat exchange by the radiant terminal device is determined based on whether the first indoor temperature meets the preset comfort conditions of the target space. The preset comfort conditions indicate that the temperature of the target space has reached a comfortable state. In this embodiment, if the first indoor temperature meets the preset comfort conditions, the environmental control system is controlled to stop both the convective heat exchange device and the radiant terminal device from exchanging heat; if the first indoor temperature does not meet the preset comfort conditions, the environmental control system is controlled to stop the convective heat exchange device from exchanging heat while the radiant terminal device continues to exchange heat.

[0160] In this embodiment, the heat exchange state is the heating state, and the preset comfort condition includes a temperature difference between the indoor temperature and the set temperature corresponding to the target space that is greater than or equal to a third preset temperature difference. The second preset temperature difference is greater than the third preset temperature difference, and the third preset temperature difference can be less than 0, equal to 0, or greater than 0, with a value range of [-5℃, 10℃].

[0161] The radiant terminal device can stop heat exchange in at least one of the following ways: the sub-regulation module corresponding to the radiant terminal device is turned off, or the power supply equipment (heat pump equipment / or gas equipment, etc.) of the radiant terminal device is turned off.

[0162] In this embodiment, the radiant terminal device maintains heat exchange continuously until the heat exchange of the radiant terminal device to the target space is sufficient after the heat exchange of the convective heat exchange device stops, as determined by the first temperature state parameter. Only then is it determined whether to stop the radiant terminal device. Based on this, it is beneficial to avoid excessive heat exchange in the system during the heat exchange of the convective heat exchange device and to avoid insufficient heat exchange after the heat exchange of the convective heat exchange device stops, so as to effectively reduce indoor temperature fluctuations and further improve indoor comfort.

[0163] In other embodiments, the heat exchange state is a cooling state, and the second preset condition may also include the current indoor temperature of the target space being less than or equal to a preset comfort temperature and / or the temperature difference between the maximum temperature in the target space and the current indoor temperature of the target space after the convective heat exchange state stops being less than or equal to a preset temperature difference, etc.

[0164] In other embodiments, the heat exchange state is a cooling state, and the preset comfort conditions may also include the temperature difference between the first indoor temperature and the set temperature corresponding to the target space being less than or equal to the preset temperature difference.

[0165] In other embodiments, the first preset comfort temperature may also be the average of a first temperature threshold and a first upper limit temperature.

[0166] In one feasible implementation, step S40 includes: if the first temperature state parameter does not meet the second preset condition, controlling the operation of the environmental conditioning system to maintain heat exchange by the radiant terminal device, and obtaining the second temperature state parameter of the target space; controlling whether the environmental conditioning system starts the convective heat exchange device for heat exchange according to the second temperature state parameter; wherein, the second preset condition indicates that the radiant terminal device has sufficient heat exchange capacity for the target space.

[0167] The definition and setting of the second preset condition are the same as those described above, and will not be repeated here.

[0168] The second temperature status parameter may include at least one of the following: current indoor temperature, indoor temperature change, temperature change trend, duration of indoor temperature at the preset temperature state, etc.

[0169] In this embodiment, the activation of the convection heat exchanger is determined based on whether the second temperature state parameter meets a preset energy replenishment condition. The preset energy replenishment condition indicates insufficient heating capacity of the radiant terminal device. When the second temperature state parameter meets the preset energy replenishment condition, the environmental control system is activated to keep the convection heat exchanger in a heat exchange state. When the second temperature state parameter does not meet the preset energy replenishment condition, the environmental control system is activated to keep the convection heat exchanger in a stopped state. Different preset energy replenishment conditions can be set for different heat exchange states.

[0170] In this embodiment, the heat exchange state includes a heating state, and the preset energy replenishment conditions include at least one of the following:

[0171] Condition 3.1: The temperature difference between the current indoor temperature of the target space and the corresponding set temperature is less than or equal to the fifth preset temperature difference;

[0172] Condition 3.2: The current indoor temperature of the target space is less than or equal to the preset lower limit temperature of the target space.

[0173] Regarding condition 3.1, the second, third, and fourth preset temperature differences mentioned above are all greater than the fifth preset temperature difference. The fifth preset temperature difference can be less than 0, equal to 0, or greater than 0, and its value range is [-5℃, 10℃].

[0174] Regarding condition 3.2, the preset lower limit temperature is the minimum temperature that the target space can comfortably tolerate when the radiant terminal device is in heating mode and the convective heat exchange device is stopped.

[0175] While controlling the operation of the environmental control system to maintain heat exchange in the radiant terminal device, the convective heat exchange device remains stopped from heat exchange. Specifically, if the first temperature state parameter does not meet the second preset condition, the environmental control system can be controlled to maintain heat exchange in the radiant terminal device and stop heat exchange in the convective heat exchange state for a set duration before acquiring the second temperature state parameter.

[0176] If the second temperature state parameter meets the preset energy replenishment conditions, the process can return to step S10.

[0177] In this embodiment, if the first temperature state parameter does not meet the second preset condition, it can be considered that after the convection heat exchanger stops heat exchange, using the radiant terminal device alone to heat the target space may result in insufficient heat exchange and fail to meet the comfort requirements of the target space. At this time, the radiant terminal device maintains forced heat exchange, and further controls whether the convection terminal device restarts heat exchange based on the observed temperature state of the target space, thereby avoiding the large temperature fluctuation of the target space caused by insufficient heat exchange of the radiant terminal device after the convection heat exchanger stops heat exchange, so as to further improve indoor comfort.

[0178] In other embodiments, when the heat exchange state is the heating state, the preset energy replenishment condition may also include that the temperature drop value of the target space from the initial moment when the convective heat exchange device stops heat exchange to the current moment when the first preset condition is met is greater than a preset amplitude.

[0179] In other embodiments, when the heat exchange state is a cooling state, the preset energy replenishment conditions may also include at least one of the following: the temperature difference between the current indoor temperature of the target space and the corresponding set temperature is greater than or equal to the preset temperature difference; the current indoor temperature of the target space is greater than or equal to the preset upper limit temperature of the target space.

[0180] In one feasible implementation, after the step of controlling the operation of the environmental control system to keep the convective heat exchange device stopped from exchanging heat when the second temperature state parameter does not meet the preset energy replenishment condition, the method further includes: controlling whether the environmental control system stops the heat exchange of the radiant terminal device according to the second indoor temperature of the target space.

[0181] The decision to stop heat exchange by the radiant terminal device is determined based on whether the second indoor temperature meets the preset comfort conditions of the target space. The preset comfort conditions indicate that the temperature of the target space has reached a comfortable state. In this embodiment, if the second indoor temperature meets the preset comfort conditions, the environmental control system is controlled to stop both the convective heat exchange device and the radiant terminal device from exchanging heat; if the second indoor temperature does not meet the preset comfort conditions, the environmental control system is controlled to stop the convective heat exchange device from exchanging heat while the radiant terminal device continues to exchange heat.

[0182] In this embodiment, the heat exchange state is the heating state, and the preset comfort condition includes a temperature difference between the indoor temperature and the set temperature corresponding to the target space that is greater than or equal to a third preset temperature difference. The second preset temperature difference is greater than the third preset temperature difference, and the third preset temperature difference can be less than 0, equal to 0, or greater than 0, with a value range of [-5℃, 10℃].

[0183] The radiant terminal device can stop heat exchange in at least one of the following ways: the sub-regulation module corresponding to the radiant terminal device is turned off, or the power supply equipment (heat pump equipment / or gas equipment, etc.) of the radiant terminal device is turned off.

[0184] The radiant terminal device maintains heat exchange status until the preset comfort conditions are met.

[0185] In this embodiment, if the second preset condition is not met during the heat exchange process of the convection heat exchanger, and the preset energy replenishment condition is still not met, it can be assumed that the heat exchange during the heat exchange process of the radiant terminal device alone is sufficient. At this time, it is determined whether to stop the radiant terminal device. Based on this, it is beneficial to avoid excessive heat exchange in the system during the heat exchange process of the convection heat exchanger and to avoid insufficient heat exchange after the heat exchanger stops, so as to effectively reduce indoor temperature fluctuations and further improve indoor comfort.

[0186] In other embodiments, after the step of controlling the operation of the environmental control system to keep the convection heat exchange device stopped from heat exchange when the second temperature state parameter does not meet the preset energy replenishment condition, it can also be determined whether the temperature state parameter of the target space meets the second preset condition. If the second preset condition is met, the environmental control system is controlled to keep the convection heat exchange device stopped from heating, and the environmental control system is controlled to stop the heat exchange of the radiant terminal device according to the indoor temperature of the target space; if the second preset condition is not met, the step of obtaining the second temperature state parameter of the target space is returned to execution.

[0187] To better understand the control scheme of the environmental control system involved in this embodiment, the following will be combined with... Figure 6 The following is an example of an application of the above solution, and the relevant process is as follows:

[0188] Step S10: Control the operation of the environmental control system to ensure that both the convective heat exchange device and the radiative terminal device in the target space are in a heat exchange state;

[0189] Step S20: Under the condition of satisfying the first preset condition, control the operation of the environmental control system to stop the heat exchange of the convection heat exchange device and maintain the heat exchange state of the radiation terminal device;

[0190] Step S30: Obtain the first temperature state parameter of the target space;

[0191] Step S41: Determine whether the first temperature state parameter meets the second preset condition;

[0192] If the first temperature state parameter meets the second preset condition, step S42 is executed; if the second temperature state parameter does not meet the second preset condition, steps S43 and S44 are executed.

[0193] Step S42: Control the operation of the environmental conditioning system to keep the convection heat exchange device from heating, and determine whether the first indoor temperature of the target space meets the preset comfort conditions;

[0194] If the first indoor temperature meets the preset comfort conditions, proceed to step S421; if the first indoor temperature does not meet the preset comfort conditions, return to proceed to step S42.

[0195] Step S421: Control the operation of the environmental control system to stop both the convective heat exchange device and the radiant terminal device from exchanging heat;

[0196] Step S43: Control the operation of the environmental control system to maintain heat exchange by the radiant terminal device and obtain the second temperature state parameter of the target space;

[0197] Step S44: Determine whether the second temperature state parameter meets the preset energy replenishment condition;

[0198] If the second temperature state parameter meets the preset energy replenishment condition, return to step S10; if the second temperature state parameter does not meet the preset energy replenishment condition, execute steps S441 and S442.

[0199] Step S441: Control the operation of the environmental control system to keep the convection heat exchange device from exchanging heat.

[0200] Step S442: Determine whether the second indoor temperature of the target space meets the preset comfort conditions;

[0201] If the first indoor temperature meets the preset comfort conditions, proceed to step S443; if the first indoor temperature does not meet the preset comfort conditions, return to proceed to step S442.

[0202] Step S443: Control the operation of the environmental control system to stop both the convective heat exchange device and the radiative terminal device from exchanging heat.

[0203] In this embodiment, by adopting the above method, it is possible to avoid excessive heat exchange during the heat exchange process of the convection heat exchanger and insufficient heat exchange during the heat exchange process of the radiant terminal device alone after the convection heat exchanger stops heat exchange. This enables the convection heat exchanger and the radiant terminal device to work in coordination, effectively reducing temperature fluctuations in the target space and effectively improving indoor comfort.

[0204] 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 method further includes:

[0205] Control the operation of the environmental control system to keep the radiant terminal device in a heat exchange state;

[0206] When the preset function is enabled and the temperature parameters of the target space meet the preset energy replenishment conditions, the step of controlling the operation of the environmental conditioning system is executed to ensure that both the convective heat exchange device and the radiative terminal device in the target space are in a heat exchange state.

[0207] The preset functions and preset energy replenishment conditions here are consistent with the relevant implementation methods mentioned in the above embodiments, and will not be repeated here.

[0208] In this embodiment, during the heat exchange process of the radiant terminal device alone, when the preset function is activated and the temperature status parameters meet the preset energy replenishment conditions, the heat exchange of the convection heat exchange device is started, so that the convection heat exchange device and the radiant terminal device can exchange heat on the target space at the same time, thereby ensuring that the environmental control system has sufficient heat exchange on the target space and effectively improving indoor comfort.

[0209] In one feasible implementation, after the step of controlling the operation of the environmental conditioning system to put the radiant terminal device in a heat exchange state, the method further includes: when the preset function is in the on state and the temperature state parameters of the target space do not meet the preset energy replenishment conditions, controlling the operation of the environmental conditioning system to stop the convective heat exchange device from heat exchange and the radiant terminal device to maintain the heat exchange state, and judging at preset intervals whether the temperature state parameters of the target space meet the preset energy replenishment conditions, until the preset energy replenishment conditions are met and the convective heat exchange device is started to exchange heat.

[0210] When the heat exchange capacity of the radiant terminal device is sufficient, using the radiant terminal device alone to exchange heat in the target space is beneficial to improving indoor comfort.

[0211] In one feasible implementation, after the step of controlling the operation of the environmental conditioning system to put the radiant terminal device in a heat exchange state, the method further includes: when the preset function is in a closed state, controlling whether the environmental conditioning system stops the heat exchange of the radiant terminal device based on the third indoor temperature of the target space.

[0212] The decision to stop heat exchange in the radiant terminal device based on the third indoor temperature control system can be compared to the decision to stop heat exchange in the radiant terminal device based on the first or second indoor temperature control system, and will not be elaborated upon here.

[0213] In this embodiment, when the preset function is off, the convection heat exchanger is not used for heat exchange. Instead, the target space is conditioned solely by the radiant terminal device, thereby meeting the user's needs for the equipment while ensuring indoor comfort.

[0214] Based on any of the above embodiments, the temperature parameters related to the target space can be obtained directly or by temperature conversion detected at at least one of the following indoor locations: the return air vent of the convection heat exchange device in the target space, the wired controller in the target space, the air outlet of the convection heat exchange device in the target space, the area where the radiant terminal device is located in the target space, etc.
