Description

Technical Field

[0002] With the improvement of living standards, people have higher and higher requirements for indoor temperature, humidity and air quality, which requires the combination of multiple terminal forms to provide a comfortable environment indoors. At present, the room is heated by inputting heat medium into the floor heating system, and the cooling is cooled by inputting refrigerant into the cooling radiation panel, and a fan coil is configured. By inputting heat medium or refrigerant into the coil, the fan drives the airflow to pass through, and the heated or cooled airflow is delivered to the room to quickly adjust the room temperature. At the same time, a fresh air system is also configured, which uses the fresh air system to transport fresh air to the room to adjust the indoor air quality, and uses the humidification and dehumidification devices in the fresh air system to adjust the fresh air humidity, thereby adjusting the indoor humidity. Therefore, there are four terminal forms in a room: cooling radiation panel, floor heating system, fan coil and fresh air unit.

[0065] Figure 1 Schematic diagram of a temperature and humidity multi-terminal control system according to an embodiment of the present invention. Figure 1 As shown, the temperature and humidity multi-terminal control system includes a manifold 1, a fresh air unit 2, multiple terminal adjustment groups 3 and an integrated control single chip computer 4.

[0066] The manifold 1 includes a manifold 11 and a manifold 12. The manifold 11 is provided with a water supply port and a plurality of water supply ports. The manifold 12 is provided with a plurality of water collection ports and a water return port. The water supply port is connected to a water supply pipe 13, and the water return port is connected to a water return pipe 14. A humidifying device and a dehumidifying device are provided in the fresh air unit 2. The air supply port of the fresh air unit 2 is connected to an air supply main pipe 5. The air supply main pipe 5 is connected to a plurality of air supply branch pipes 6. An air supply valve 7 is installed on each air supply branch pipe 6. Each terminal adjustment group 3 includes a thermostat 31, a heat exchange radiation plate 32, a floor heating pipe 33 and a fan coil 34. Each thermostat 31 is provided with a temperature and humidity sensor. The inlet of a heat exchange radiation plate 32 and the inlet of a floor heating pipe 33 are respectively connected to a water distribution port through a water distribution pipe 15, and the outlet of each heat exchange radiation plate 32 and the outlet of the floor heating pipe 33 are respectively connected to a water collection port through a water collection pipe. A water distribution valve 16 is installed at each water distribution port, and multiple terminal adjustment groups 3 are correspondingly arranged with multiple air supply branch pipes 6; the input end of the integrated control single-chip microcomputer 4 is communicatively connected to the output end of the temperature controller 31, and the output end of the integrated control single-chip microcomputer 4 is communicatively connected to the control end of the fresh air unit 2, the control end of each air supply valve 7, the control end of each fan coil 34 and the control end of each water distribution valve 16.

[0067] When in use, connect an air supply branch pipe 6 to a room, install a terminal adjustment group 3 in a room, connect the heat exchange radiation plate 32 and the floor heating pipe 33 to the water distributor 11 through the water distributor pipe 15, and connect them to the water collector 12 through the water collector pipe. When the user needs to adjust the indoor temperature and humidity, the cooling mode or heating mode is selected through the integrated control single chip microcomputer 4, and the thermostat 31 is turned on. The integrated control single chip microcomputer 4 reads that the thermostat 31 is started, that is, the fresh air unit 2 is controlled to start, and at the same time, the air supply valve 7 in each air supply branch pipe 6 is controlled to open to a certain opening, so that the fresh air unit 2 delivers fresh air to the room. The set temperature and set humidity of the thermostat 31 are manually input. The temperature and humidity sensor in the thermostat 31 monitors the actual temperature and actual humidity in the room in real time, and transmits the set temperature, set humidity, actual temperature and actual humidity to the integrated control single chip microcomputer 4. The integrated control single chip computer 4 compares the actual humidity with the set humidity. If the actual humidity is lower than the set humidity, it indicates that the room needs humidification. At this time, the integrated control single chip computer 4 controls the start-up of the humidification device in the fresh air unit 2 to realize the humidification function; if the actual humidity is higher than the set humidity, it indicates that the room needs dehumidification. At this time, the integrated control single chip computer 4 controls the start-up of the dehumidification device in the fresh air unit 2 to realize the dehumidification function.

[0068] In cooling mode, if the actual indoor temperature is lower than the set temperature, the integrated control single chip microcomputer 4 controls the water diversion valve 16 on the manifold 1 corresponding to the heat exchange radiation plate 32 and the floor heating pipe 33 in the room to be closed, and the refrigerant will not be input into the heat exchange radiation plate 32 and the floor heating pipe 33, and the heat exchange radiation plate 32 and the floor heating pipe 33 are in a non-working state. At the same time, the fan coil 34 is controlled to be in a shut-down state; if the actual temperature is higher than the set temperature, the integrated control single chip microcomputer 4 can control the water diversion valve 16 corresponding to the heat exchange radiation plate 32 to open to introduce the refrigerant, control the water diversion valve 16 corresponding to the floor heating pipe 33 to open to introduce the refrigerant, or control the fan coil 34 to start, so as to cool down the room. According to the specific temperature range in which the actual temperature is higher than the set temperature, the integrated control single chip microcomputer 4 can control one of the three terminals to work alone, or two terminals to work in combination, or three terminals to work simultaneously. The larger the temperature range in which the actual temperature is higher than the set temperature, the more terminal devices are controlled to be started.

[0069] In the heating mode, if the actual indoor temperature is greater than the set temperature, the integrated control single chip microcomputer 4 controls the water diversion valve 16 on the manifold 1 corresponding to the heat exchange radiation plate 32 and the floor heating pipe 33 in the room to be closed, so that the heat medium will not be input into the heat exchange radiation plate 32 and the floor heating pipe 33, and the heat exchange radiation plate 32 and the floor heating pipe 33 are in a non-working state. At the same time, the fan coil 34 is controlled to be in a shut-down state; if the actual temperature is lower than the set temperature, the integrated control single chip microcomputer 4 can control the water diversion valve 16 corresponding to the heat exchange radiation plate 32 to open to introduce the heat medium, control the water diversion valve 16 corresponding to the floor heating pipe 33 to open to introduce the heat medium, or control the fan coil 34 to start, so as to increase the indoor temperature. According to the specific temperature range that the actual temperature is lower than the set temperature, the integrated control single chip microcomputer 4 can control one of the three terminals to work alone, or two terminals to work in combination, or three terminals to work simultaneously. The larger the temperature range that the actual temperature is lower than the set temperature, the more terminal devices are controlled to be started.

[0070] By adopting the temperature and humidity multiple terminal form control system of the present invention, the user only needs to set the temperature and humidity on the thermostat 31, and with the help of a set of integrated control single-chip microcomputer 4, the four terminal devices of heat exchange radiation plate 32, floor heating pipe 33, fan coil 34 and fresh air unit 2 can be centrally controlled to operate jointly, and finally the temperature and humidity set by the user are achieved, which simplifies the adjustment process and can bring better and more convenient operation experience to the user.

[0071] like Figure 1As shown, in this embodiment, there are three rooms, each of which is equipped with one or two terminal adjustment groups 3, that is, each is equipped with a thermostat 31, a heat exchange radiation plate 32, a floor heating pipe 33 and a fan coil 34. The air supply port of the fresh air unit 2 is connected to the air supply main 5, and the air supply main 5 is connected to multiple air supply branches 6. The air supply branch 6 is connected to the room, and an air supply valve 7 is arranged in the air supply branch 6. The inlet of the heat exchange radiation plate 32 and the floor heating pipe 33 is connected to the water distribution port of the water distributor 11 through the water distribution pipe 15, and the outlet of the heat exchange radiation plate 32 and the floor heating pipe 33 is connected to the water collection port of the water collector 12 through the water collection pipe. In order to prevent too many pipes and cause confusion in the figure, Figure 1 Only the water distribution pipe 15 is shown, and the connection between the water collecting pipe and the heat exchange radiation plate 32, the floor heating pipe 33 and the water collector 12 is not shown. The integrated control microcontroller 4 can be connected to each terminal by wire or by wireless. The heat exchange radiation plate 32, the floor heating pipe 33, the fan coil 34 and the fresh air unit 2 are all mature existing technologies, and their specific structures and working principles are not repeated here.

[0072] Optionally, the temperature and humidity multi-terminal form control system also includes a valve control microcontroller 8, the input end of the valve control microcontroller 8 is communicatively connected to the output end of the integrated control microcontroller 4, and the output end of the valve control microcontroller 8 is communicatively connected to the control end of each water diversion valve 16.

[0073] The valve control microcontroller 8 is added so that the valve control microcontroller 8 can independently control the opening and closing of the water diversion valves 16 corresponding to the floor heating pipes 33 and the heat exchange radiation plates 32 according to the output command signal of the integrated control microcontroller 4, which is convenient for classification management. The valve control microcontroller 8 is connected to each water diversion valve 16, which also avoids all communication lines being connected to the integrated control microcontroller 4, resulting in too many lines at the integrated control microcontroller 4. The thermostat 31 transmits the data of the set temperature and the actual temperature to the integrated control microcontroller 4. After the integrated control microcontroller 4 performs logical operations inside, it determines whether the heat exchange radiation plates 32 and the floor heating pipes 33 are started and operated, and transmits the command signal of whether to start to the valve control microcontroller 8. The valve control microcontroller 8 controls whether the water diversion valves 16 corresponding to the heat exchange radiation plates 32 and the floor heating pipes 33 are opened according to the command signal.

[0074] Optionally, the temperature and humidity multiple terminal form control system further includes a first temperature sensor 9 and a second temperature sensor 10. The first temperature sensor 9 is installed on the water supply pipe 13 to detect the water supply temperature; the second temperature sensor 10 is installed on the return water pipe 14 to detect the return water temperature; the output ends of the first temperature sensor 9 and the second temperature sensor 10 are respectively connected to the input end of the valve control microcontroller 8 for communication.

[0075] When the heat exchange radiation plate 32 is in working state, its radiation surface temperature is lower than the air dew point temperature, condensation water will be generated on the surface of the heat exchange radiation plate 32, causing damage to the decorative wall or ceiling. In order to avoid this situation, it is necessary to monitor the radiation surface temperature. When the radiation surface temperature is lower than the indoor dew point temperature, the water diversion valve 16 on the manifold 1 corresponding to the heat exchange radiation plate 32 should be closed to put the heat exchange radiation plate 32 in a non-working state. However, the fan coil 34 is not affected by the indoor dew point temperature and can therefore operate normally.

[0076] The first temperature sensor 9 detects the water supply temperature ntc1 in real time, and the second temperature sensor 10 detects the return water temperature ntc2 in real time, and transmits the water supply temperature ntc1 and the return water temperature ntc2 to the valve control microcontroller 8. The valve control microcontroller 8 can calculate the radiation surface temperature Tb of the heat exchange radiation plate 32, Tb = (ntc1 + ntc2) / 2 + a, where a is the additional value for calculating the radiation surface temperature, the default is 2.5°C, and this value can be set according to the material of the heat exchange radiation plate 32.

[0077] The integrated control microcontroller 4 obtains the actual indoor temperature Tn and actual humidity detected by the thermostat 31 And calculate the dew point temperature Td, Td = ((0.66077-X)*237.3) / (X-8.16077), where, The dew point temperature is transmitted to the valve control microcontroller 8. The humidity data detected by the thermostat 31 are all relative humidity.

[0078] In the valve control microcontroller 8, the dew point temperature Td is compared with the radiation surface temperature Tb. If Tb≤Td, it indicates that the heat exchange radiation plate 32 may condense. At this time, the valve control microcontroller 8 controls the water diversion valve 16 of the manifold 1 corresponding to the heat exchange radiation plate 32 to be closed, and no refrigerant is input into the heat exchange radiation plate 32; if Tb>Td+0.5, it indicates that the heat exchange radiation plate 32 will not condense. At this time, the valve control microcontroller 8 controls whether the water diversion valve 16 of the manifold 1 corresponding to the heat exchange radiation plate 32 is opened according to the comparison result of the actual temperature and the set temperature.

[0079] Figure 2 for Figure 1 The schematic diagram of the valve control microcontroller of the temperature and humidity multi-terminal form control system shown; Figure 3 for Figure 2 The figure shows the connection relationship between the valve control microcontroller and the manifold. Figure 2 and Figure 3As shown, optionally, the valve control microcontroller 8 includes a first shell 84, a first circuit board (not shown), a first power terminal 81, a first communication terminal 82, a first temperature terminal 85, a second temperature terminal 86 and a plurality of valve terminals 83, the first circuit board is fixed in the first shell 84, the first power terminal 81, the first communication terminal 82, the first temperature terminal 85, the second temperature terminal 86 and the plurality of valve terminals 83 respectively pass through the first shell 84 and are connected to the first circuit board; the first power terminal 81 is used to connect the first power source; the first communication terminal 82 is connected to the output end of the integrated control microcontroller 4; the first temperature terminal 85 is connected to the output end of the first temperature sensor 9; the second temperature terminal 86 is connected to the output end of the second temperature sensor 10; a valve terminal 83 is connected to the control end of a water diversion valve 16.

[0080] like Figure 2 As shown, the lower left corner of the valve control microcontroller 8 is the first power terminal 81, which is used to connect the power supply, and the upper left corner is the first communication terminal 82, the first temperature terminal 85 and the second temperature terminal 86. The integrated control microcontroller 4 transmits the command signal and related data to the valve control microcontroller 8 through the first communication terminal 82, the first temperature sensor 9 transmits the water supply temperature to the valve control microcontroller 8 through the first temperature terminal 85, and the second temperature sensor 10 transmits the return water temperature to the valve control microcontroller 8 through the second temperature terminal 86. The others are valve terminals 83, and the number of valve terminals 83 is greater than the number of water diverter valves 16. When a valve terminal 83 is connected to the circuit where the corresponding water diverter valve 16 is located, the water diverter valve 16 is opened, and when the circuit is disconnected, the water diverter valve 16 is closed.

[0081] Optionally, each of the terminal adjustment groups 3 also includes an air disc control microcontroller 35, the input end of the air disc control microcontroller 35 is communicatively connected to the output end of the integrated control microcontroller 4, and the output end of the air disc control microcontroller 35 is communicatively connected to the control end of the fan coil 34 and the control end of the air supply valve 7.

[0082] The fan coil control single chip microcomputer 35 is added so that the fan coil control single chip microcomputer 35 can independently control the start and stop of the fan coil 34 and the opening and closing of the air supply valve 7 according to the output instruction of the integrated control single chip microcomputer 4, which is convenient for classification management. The fan coil control single chip microcomputer 35 is connected to the fan coil 34, which also avoids all communication lines being connected to the integrated control single chip microcomputer 4, resulting in too many lines at the integrated control single chip microcomputer 4. The thermostat 31 transmits the data of the set temperature and the actual temperature to the integrated control single chip microcomputer 4. After the integrated control single chip microcomputer 4 performs logical operations inside, it determines whether the fan coil 34 is started and running, whether the air supply valve 7 is opened, and transmits the command signal of whether to start to the fan coil control single chip microcomputer 35.

[0084] When the air valve opening terminal 355 is connected to the circuit of the start terminal for controlling the opening of the air supply valve 7 in the corresponding air supply branch pipe 6, the air supply valve 7 is opened, and the fresh air unit 2 delivers fresh air into the room through the air supply branch pipe 6; when the air valve closing terminal 356 is connected to the circuit of the stop terminal for controlling the closing of the corresponding air supply valve 7, the air supply valve 7 is closed, and the fresh air unit 2 cannot deliver fresh air into the room. When the integrated control single chip computer 4 obtains that the thermostat 31 is in the starting state, it determines that the fresh air unit 2 needs to be started, and outputs a start signal to the air disk control single chip computer 35, and the air disk control single chip computer 35 controls the fresh air unit 2 to start, and at the same time controls the circuit of the air valve opening terminal 355 to be turned on.

[0085] Valves are installed on the water inlet pipes of different types of fan coil units 34. The fan coil units 34 are all provided with opening terminals and closing terminals. When the circuit where the opening terminal is located is connected, the valve on the water inlet pipe is opened, the water inlet pipe is connected, and the refrigerant or heat medium can be transported to the coil. When the circuit where the closing terminal is located is connected, the valve is closed, the water inlet pipe is disconnected, and the refrigerant or heat medium cannot be transported to the coil. The three-speed fan coil unit is provided with low-end terminals, mid-range terminals and high-end terminals, which can control the wind speed of low, medium and high gears. When the circuit where the low-end terminal is located is connected, the three-speed fan coil unit runs at a low wind speed. When the circuit where the mid-range terminal is located is connected, the three-speed fan coil unit runs at a medium wind speed. When the circuit where the high-end terminal is located is connected, the three-speed fan coil unit runs at a high wind speed. The DC brushless fan coil unit 34 is provided with an operating terminal. After the circuit where the operating terminal is located is connected, the motor speed can be controlled according to the voltage change, thereby controlling the wind speed.

[0086] If the fan coil type is a three-speed fan coil, the water valve opening terminal 353 is connected to the opening terminal of the three-speed fan coil through a line, the water valve closing terminal 354 is connected to the closing terminal of the three-speed fan coil through a line, and the low-speed terminal 357, the medium-speed terminal 358 and the high-speed terminal 359 are respectively connected to the low-speed terminal, the medium-speed terminal and the high-speed terminal of the three-speed fan coil through lines. When the user manually selects the running gear in advance, the command signal output by the integrated control single-chip computer 4 indicates that the fan coil 34 starts, the fan disk control single-chip computer 35 controls the circuit where the water valve opening terminal 353 is located to be turned on, and controls the circuit where the corresponding low-speed terminal 357, the medium-speed terminal 358 or the high-speed terminal 359 is located to be turned on.

[0087] If the fan coil type is a DC brushless fan coil, the water valve opening terminal 353 is connected to the opening terminal of the DC brushless fan coil through a line, the water valve closing terminal 354 is connected to the closing terminal of the DC brushless fan coil through a line, and the DC brushless fan coil control terminal 3510 is connected to the running terminal of the DC brushless fan coil. When the command signal output by the integrated control single chip computer 4 indicates that the fan coil 34 is started, the fan coil control single chip computer 35 controls the circuit where the water valve opening terminal 353 is located to be turned on.

[0088] Optionally, each terminal adjustment group 3 further includes an air quality sensor (not shown), and the output end of the air quality sensor is communicatively connected to the input end of the integrated control single chip computer 4. When the fresh air unit 2 is started, the air supply valve 7 is opened at a small degree. When the indoor air quality is poor, fresh air needs to be quickly delivered to the room, so the opening of the air supply valve 7 is appropriately increased.

[0089] The air quality sensor monitors the indoor air quality data in real time and transmits the air quality data to the integrated control microcontroller 4. The integrated control microcontroller 4 has a preset air quality. When the monitored air quality data is greater than the set air quality, it indicates that the indoor air is poor. At this time, the integrated control microcontroller 4 controls the opening of the air supply valve 7 to increase. When the air disk control microcontroller 35 is provided, the integrated control microcontroller 4 can transmit the command signal for controlling the opening of the air supply valve 7 to increase the opening of the air disk control microcontroller 35, and the air disk control microcontroller 35 directly controls the increase of the opening of the air supply valve 7. The air quality sensor can monitor the indoor PM2.5 concentration data, or the TVOC (total volatile organic compound) concentration data, etc.

[0090] The present invention also provides a temperature and humidity multiple terminal form control method, based on the temperature and humidity multiple terminal form control system described in any of the above embodiments, comprising the following steps:

[0091] S1: Install a terminal adjustment group 3 in a room;

[0092] S2: Inputting the set temperature and set humidity into the thermostat 31;

[0093] S3: Using the temperature and humidity sensor in the thermostat 31 to obtain the actual temperature and humidity in the room;

[0094] S4: The integrated control single chip computer 4 controls the water diversion valve 16 on the manifold 1 corresponding to the heat exchange radiation plate 32 and the floor heating pipe 33 in the terminal adjustment group 3 to open or close according to the comparison result between the actual temperature and the set temperature, and controls the start or stop of the fan coil 34 at the same time;

[0095] S5: The integrated control single chip computer 4 controls the fresh air unit 2 to be in a humidification state, a dehumidification state or a ventilation state according to the comparison result between the actual humidity and the set humidity.

[0096] Since the control instructions of the terminal device are sent after the centralized control microcontroller obtains the data of the thermostat 31 and makes a logical judgment, there must be a relationship configuration between the terminal device and the thermostat 31. After the relationship configuration is completed, the centralized control microcontroller performs a logical strategy operation based on the actual temperature and the set temperature data, and determines which terminal form or forms to start based on the operation results. The basis of the relationship configuration is the thermostat 31. After multiple terminal adjustment groups 3 are installed in different rooms, the relationship configuration is performed. The following takes the temperature and humidity multiple terminal form control system equipped with a fan disk control microcontroller 35 and a valve control microcontroller 8 as an example for configuration description.

[0097] like Figure 1As shown, there are three rooms, namely Room 1, Room 2 and Room 3 from left to right, wherein the terminal adjustment group 3 in Room 1 includes two groups of heat exchange radiation panels 32, two groups of floor heating pipes 33 and two fan coil units 34, and the terminal adjustment groups 3 in Room 2 and Room 3 include one group of heat exchange radiation panels 32, one group of floor heating pipes 33 and one fan coil unit 34 respectively, and a thermostat 31 is arranged in each room.

[0098] The relationship configuration process is as follows:

[0099] Step 1: Define the device number. The device number is implemented in the program and is numbered according to the communication address. For example, if the communication address of the thermostat is 1, you can define communication address 1 as number 1. The communication address of the valve control microcontroller is 31, so you can define communication address 31 as number 1. If there are two valve control microcontrollers and the other communication address is 32, you can define communication address 32 as number 2. The communication addresses of the fan disk control microcontroller are 21, 22, and 23 respectively. Then you can define communication addresses 21, 22, and 23 as fan disk control microcontroller numbers 1, 2, and 3 respectively. Figure 1 In the figure, from left to right, the thermostats correspond to number 1, number 2, number 3, and the fan disk control microcontrollers correspond to number 1, number 2, number 3, and number 4. The valve control microcontroller corresponds to number 1, and the fresh air unit corresponds to number 1.

[0100] Step 2: Configure the relationship between the room name and the thermostat number. According to the room where the thermostat is installed, configure the corresponding relationship between the room and the thermostat number, such as Figure 1 As shown, the thermostat corresponding to room one is numbered 1, the thermostat corresponding to room two is numbered 2, and the thermostat corresponding to room three is numbered 3.

[0101] Step 3: Set the temperature adjustment method. The temperature adjustment method can be divided into A-floor heating pipes, B-heat exchange radiation panels, C-fan coils, or a combination of any two terminals such as AB-floor heating pipes + heat exchange radiation panels, AC-floor heating pipes + fan coils, BC-heat exchange radiation panels + fan coils, or ABC-floor heating pipes + heat exchange radiation panels + fan coils, all three terminals are enabled.

[0102] Step 4: Configure the number of the valve control microcontroller corresponding to the thermostat. When there are multiple valve control microcontrollers, it is necessary to determine the number of the valve control microcontroller corresponding to the water distribution valve of the manifold corresponding to the room where the thermostat is located.

[0103] Step 5: Configure the corresponding relationship between each thermostat and the water distribution valves on the manifold corresponding to the heating pipes and heat exchange radiation panels. That is, determine which water distribution valves on the manifold correspond to the thermostat in each room.

[0104] Step 6: Define the properties of each valve terminal on the valve control microcontroller, that is, each valve terminal (water diversion valve) corresponds to which heat exchange radiation panel or which floor heating pipe.

[0105] Step 7: Configure the temperature controller and fan disk control microcontroller number, such as Figure 1 As shown, fan disk control microcontrollers No. 1 and No. 2 are in room one, corresponding to thermostat No. 1, fan disk control microcontroller No. 3 is in room two, corresponding to thermostat No. 2, and fan disk control microcontroller No. 4 is in room three, corresponding to thermostat No. 3.

[0106] Step 8: Configure the thermostat and the fresh air unit number. When multiple fresh air units are used, the fresh air units must be numbered, such as Figure 1 As shown, one fresh air unit supplies fresh air to three rooms, so thermostats No. 1, No. 2 and No. 3 all correspond to fresh air unit No. 1.

[0107] Step 9. Configure the primary and secondary relationships of the terminal devices according to the mode. The primary and secondary relationships can define different terminal devices at will. For example, in cooling mode, the heat exchange radiation panel is the primary cooling, the floor heating pipe is the secondary cooling 1, and the fan coil is the secondary cooling 2. Configure the primary and secondary relationships according to the room requirements.

[0108] Step 10, set the judgment temperature for starting the auxiliary terminal. For example, the actual temperature is Tn, the set temperature is Tsd, in the cooling mode, when Tsd≤Tn<Tsd+△t1, only the main cooling terminal heat exchange radiation plate is started; when Tsd+△t1≤Tn<Tsd+△t1+△t2, in addition to the main cooling terminal heat exchange radiation plate, the auxiliary 1 cooling terminal floor heating pipe is started at the same time; when Tn≥Tsd+△t1+△t2, the main cooling terminal heat exchange radiation plate, the auxiliary 1 cooling terminal floor heating pipe, and the auxiliary 2 cooling terminal fan coil are all started.

[0109] The above configuration relationship can be summarized as Table 1.

[0125] Among them, the specific values ​​of △t1, △t2, △t3 and △t4 can be adjusted appropriately. In addition, only one terminal device for auxiliary cooling or heating can be set. For example, when heating, the floor heating pipe 33 is set as the main heating terminal, the heat exchange radiation plate 32 is set as the auxiliary heating terminal, and the fan coil 34 does not participate in heating.

[0126] Optionally, in step S5, it specifically includes:
