Description

Technical Field

[0001] The present invention relates to the technical field of radiation air conditioning equipment and application methods, in particular to a multifunctional radiation air conditioner and an application method. Background Art

[0002] ‌Radiant air conditioning (TABS) is a technology that uses the radiation principle for cooling and heating. It forms a cold or hot radiant surface by lowering or raising the temperature of the inner surface of the enclosure structure, and relies on the radiant heat exchange between these radiant surfaces and the human body, furniture and other surfaces of the enclosure structure to adjust the indoor temperature. ‌Radiant air conditioning systems can heat or cool indoor air by setting hot and cold pipes in the enclosure structure, or by adding radiant panels on the ceiling or the outer surface of the wall, and laying floor heating sheets under the ground to increase or decrease the indoor temperature (for the convenience of description, the following content radiant panels and floor heating sheets are collectively referred to as transducers). The main advantages of radiant air conditioning include energy saving and comfort. Due to its reliance on radiant heat exchange, radiant air conditioning can provide sufficient heat at a lower temperature, thereby reducing energy consumption. In addition, radiant air conditioning transfers heat through building surfaces such as walls, floors or ceilings, avoiding cold wind blowing directly on the human body, and providing a more uniform and comfortable indoor environment.

[0003] The general structure of the existing radiant air conditioner includes an outdoor system and an indoor unit, a control system based on PLC, etc. The outdoor system and multiple indoor units (including a surface cooler and a fan, etc., when the fan is working, the wind force generated acts on the surface cooler, and the cold water or hot water in the surface cooler provides cooling or heat for the room), a transducer (installed on the indoor wall or ceiling), etc. are connected in parallel through pipes. When working, the outdoor system uniformly provides cooling or heating liquid for multiple indoor units and transducers. Although the above working mode meets the use needs to a certain extent, it still has the following technical disadvantages due to structural limitations. First: Since the outdoor system is connected in parallel with multiple indoor units and transducers in the room through pipes, the number of pipes required is large, and the installation and debugging are relatively troublesome, which is not conducive to improving work efficiency and increases cost investment. Second: When working, the cold or hot medium output by the outdoor system is pressurized by the booster pump and pumped out to the indoor units or transducers in each room. Due to the different number of rooms in each area, the length of the pipes used is different. If the pipe is relatively long, the room at the end of the pipe may not be effectively supplied with cold or hot medium (the pressure at the end of the pipe is lower), which will have an adverse effect on its cooling or heating. On the contrary, if the pipe is relatively short, it may cause excessive pressure in the pipe, resulting in unnecessary waste of electricity. Third: In order to achieve a good temperature control mode, the existing radiant air conditioner is equipped with humidity and temperature sensors (including ambient temperature sensors and pipe temperature sensors) at the outdoor system, and then the control system controls the temperature of the hot and cold water (that is, the refrigerant or heat medium) output by the radiant air conditioner according to the detected temperature or humidity data. The above control mode is based on the ambient temperature, humidity and pipe temperature data at the outdoor system. This will bring a problem that the relevant data at the outdoor system is actually different from the temperature and humidity of each room, and the temperature and humidity of different rooms also deviate. The unified mode cannot effectively meet the temperature and humidity adjustments of each room (for example, the indoor temperature is lower than the outdoor temperature, and the humidity is lower than the outdoor humidity. The indoor temperature and humidity cannot be consistent according to the outdoor temperature and humidity), and cannot bring a better user experience. Fourthly, the internal cooler (snake coil, fin-shaped heat-conducting and cooling fins are installed on the outside of the coil, and there is a gap between two adjacent heat-conducting and cooling fins to ensure air circulation) and the fan are distributed front and back, and the sterilizing ultraviolet sterilization lamp is installed at the air inlet of the cooler. In actual operation, the fan generates a lot of noise, and the light generated by the ultraviolet sterilization lamp is relatively easy to radiate to the outside (it can only sterilize and disinfect one side of the cooler), which more or less has an adverse effect on the health of the user. Taking the above factors into consideration, it is particularly necessary to provide a radiation air conditioner and application method that integrates multiple functions, is easy to install, automatically debugs, and can bring better user experience. Summary of the invention

[0004] In order to overcome the drawbacks of the existing radiation air conditioner as described in the background technology due to structural limitations, the present invention provides a multifunctional radiation air conditioner and an application method that integrates multiple devices of the indoor unit together and has a compact structure. The indoor unit and the outdoor unit system installed in each room are connected in parallel through pipes, and the indoor unit and the transducer in each room are connected in series. During installation, the staff only needs to connect the corresponding two interfaces of the outdoor unit system with the two interfaces of the indoor unit to achieve rapid installation, thereby improving the installation speed and efficiency. Each indoor unit is provided with a booster pump, and the sensors matched with the control system of each indoor unit can collect the temperature, humidity and pipeline temperature of each room in real time. The temperature and humidity data of each room can be accurately adjusted through a three-way proportional valve, a booster pump, a fan, etc., thereby providing users with a more comfortable experience and achieving energy-saving effects. The fan and ultraviolet sterilization lamp of the indoor unit are installed on the inner side of the V-shaped structure surface cooler, thereby reducing the noise of the fan, and simultaneously sterilizing and disinfecting the inner ends of the two parts of the surface cooler, generating negative oxygen ions, and reducing the adverse effects of ultraviolet leakage on the health of users.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A multifunctional radiation air conditioner, comprising a radiation air conditioner body and an electric proportional valve having an external unit system, a control system, a temperature sensor, a humidity sensor, a booster water pump, an internal unit, an ultraviolet germicidal lamp, wherein the temperature sensor, the humidity sensor, the control system, the booster water pump, the electric proportional three-way valve, and the ultraviolet germicidal lamp are provided in multiple sets, and each set of the internal unit is equipped with a control system, a humidity sensor, a booster water pump or a pressure difference, an electric proportional three-way valve, an ultraviolet germicidal lamp, and a temperature sensor provided by the system; the surface cooler of the internal unit is an enclosed structure or a single surface cooler, the surface cooler is fixedly mounted on the inner side end or the air outlet end of the shell, the fan and the ultraviolet germicidal lamp of the internal unit are respectively fixedly mounted in the shell at the inner side end of the surface cooler, and the temperature sensor, the humidity sensor, and the control system are fixedly mounted in the shell , a probe of one set of temperature sensors is fixedly installed at the outer end of the liquid outlet pipe of the surface cooler; the liquid inlet pipe of the surface cooler is fixedly connected to the liquid outlet pipe of the booster water pump, the liquid inlet pipe of the booster water pump is fixedly connected to the liquid outlet pipe of the external unit system, the liquid outlet pipe of the surface cooler is fixedly connected to the liquid inlet end of the electric proportional valve, the first liquid outlet end of the electric proportional valve is fixedly connected to the liquid inlet pipe of the indoor transducer plate, the liquid outlet pipe of the transducer plate and the second liquid outlet end of the electric proportional valve are fixedly connected in parallel and connected to the return liquid pipe of the external unit system; the signal output ends of the humidity sensor and the two sets of temperature sensors are electrically connected to the multi-channel signal input ends of the control system respectively, and the power output end of the control system is electrically connected to the power input ends of the fan, the booster water pump, the ultraviolet sterilization lamp and the signal input end of the electric proportional valve respectively.

[0006] Furthermore, the first liquid outlet end of the electric proportional valve can be independently fixedly connected to the liquid inlet end of the radiation plate or floor heating plate, and the liquid outlet pipe of the radiation plate or floor heating plate and the second liquid outlet end of the electric proportional valve are fixedly connected in parallel to the return pipe of the external unit system.

[0007] Furthermore, the control system is not limited to PLC, but can also adopt a single chip microcomputer module or a small computer system.

[0008] Furthermore, the fan and the booster water pump are respectively a variable frequency fan and a variable frequency booster water pump, and the appearance of the surface cooler is not limited to one, and can be any one of the structures surrounding the fan.

[0009] Furthermore, the ultraviolet germicidal lamp can also be any lamp with a germicidal function.

[0010] A method for applying a multifunctional radiation air conditioner comprises the following steps: S1: after the staff installs multiple sets of outdoor systems and indoor units in place, the liquid inlet pipes of the booster water pumps of the multiple sets of indoor units are connected to the liquid outlet pipes or buffer water tanks of the outdoor systems, and the second liquid outlet end of the electric proportional valve is connected to the liquid return pipe of the outdoor system; S2: when the booster water pump is working, the cold water or hot water input from the outdoor system is pressurized and pumped into the surface cooler and the transducer plate; S3: two sets of temperature sensors and humidity sensors respectively collect the indoor temperature, the tube side temperature of the liquid outlet end of the booster water pump after passing through the surface cooler, and the indoor humidity data in real time, and then output signals that change dynamically with temperature and humidity to the control system, and the control system generates signals according to the temperature and humidity. The size of the input signal controls the operating frequency of the booster pump and the fan, as well as the valve core opening of the electric proportional valve. In heating mode, when the indoor temperature is low and the humidity is high, the operating frequency of the booster pump and the fan increases, providing more heat medium for the cooler and the transducer, and the fan blades blow out a larger amount of hot air. When it is detected that the temperature of the pipe surface (the output end of the cooler) is higher than the dew point temperature, the three-way proportional valve switches to the indoor radiation plate or radiation block, and forms a series mode with the cooler (to prevent misoperation in summer). When the indoor temperature is high and the humidity is low, the operating frequency of the booster pump and the fan decreases, providing less heat medium for the cooler and the transducer, and the fan blades blow out a smaller amount of hot air at a lower operating speed. In cooling mode, when the indoor temperature and humidity are high, the working frequency of the booster pump and the fan increases, providing more refrigerant for the cooler and the transducer. The fan blades blow out a larger amount of cold air, and the three-way proportional valve switches the cooler outlet to directly send it back to the outdoor unit system, shielding the radiation plate to prevent condensation, and lowering the indoor temperature. When it is detected that the temperature of the pipe surface (the output end of the cooler) is higher than the dew point temperature, the three-way proportional valve switches the indoor radiation plate or radiation block to form a series mode with the cooler. The temperature is lower than the set temperature and the humidity is low. At the dew point, the operating frequency of the booster pump and the fan becomes smaller, providing less refrigerant for the cooler and the transducer, and the amount of cold air blown out by the fan blades is smaller; S4: When the indoor unit is working, the external air enters the rear end of the cooler through the rear end of the shell under the action of the negative pressure generated by the fan, and the flowing air passes through the multiple fins of the cooler at the rear end, releases heat or cold through the front end of the cooler, and then outputs hot air or cold air to the indoor environment through the air vents at the front end of the shell. At the same time, the ultraviolet germicidal lamp is used to disinfect the air entering the room.

[0011] Furthermore, in the step S1, the energy conversion plate and the indoor unit no longer need to be separately connected in parallel with the liquid outlet pipe of the outdoor unit system via pipelines, thereby saving the number of pipelines, reducing the installation workload, and improving safety and efficiency.

[0012] Furthermore, in step S2, it can prevent the pipeline connecting the outdoor system and the indoor system from being too long, causing the indoor room at the end of the pipeline to be unable to effectively obtain the cold or heat medium supply, which has an adverse effect on its cooling or heating, and the pipeline is relatively short, causing excessive pressure in the pipeline, resulting in unnecessary waste of electricity. The pipeline pressure and flow debugging can be reduced, and the system pressure can be set to the lowest pressure.

[0013] Furthermore, in step S3, it is possible to prevent the indoor temperature and humidity from being controlled based on the temperature and humidity data sensor signal of the external system. There are deviations in each indoor area, and there are deviations in the temperature and humidity of different rooms. The unified mode cannot effectively meet the temperature and humidity regulation of each room, and cannot bring a better user experience to the user.

[0014] Furthermore, in step S4, the fan is installed on the inner side of the V-shaped surface cooler, and the surface cooler acts as an enclosure for the fan to reduce external noise. The light of the ultraviolet sterilization lamp is blocked by the V-shaped surface cooler, reducing the adverse effects of light leakage on the health of the user. At the same time, isothermal dehumidification can be performed, and the incoming air can be pre-cooled and sterilized by heat treatment, and then sterilized by cold and heat treatment.

[0015] Compared with the prior art, the invention has the following beneficial effects: the invention integrates multiple devices of the indoor unit together, and has a compact structure. The indoor unit and the outdoor unit system installed in each room are connected in parallel through pipes, and the indoor unit and the transducer in each room are connected in series through pipes. During installation, the staff only needs to connect the corresponding two interfaces of the outdoor unit system with the two interfaces of the indoor unit to achieve rapid installation, thereby improving the installation speed and efficiency and saving the installation cost. Each indoor unit is provided with a booster pump, and the sensors of the control system of each indoor unit can collect the temperature, humidity and pipe temperature of each room in real time. Through the flow regulation of a three-way proportional valve and a booster pump and the output power regulation of the fan, the precise temperature and humidity control of each room can be achieved relatively, and the outlet temperature is controlled at the temperature that best matches the room, thereby providing users in different rooms with a more comfortable experience and achieving energy-saving effects. The fan and ultraviolet sterilization lamp of the indoor unit are installed on the inner side of the V-shaped structure surface cooler, thereby reducing the noise of the fan, and simultaneously sterilizing and disinfecting the inner sides of the two parts of the surface cooler, and reducing the adverse effects of ultraviolet leakage on the health of users. In summary, the invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 , 2As shown in , 3, the present invention is based on the radiation air conditioner body, and uses the radiation principle to provide cooling or heating (the hot water or cold water output by the outdoor system 4 enters into the multiple indoor surface coolers 101 and the transducer 2 through the liquid outlet pipe, and the hot water after heat dissipation or the cold water after refrigeration output by the surface cooler 101 and the transducer 2 flows back into the outdoor system through the return pipe of the outdoor system 4 for recycling), and forms a cold or hot radiation surface by lowering or raising the temperature of the inner surface of the enclosure structure, and relies on the radiation heat exchange between these radiation surfaces and the human body, furniture and other surfaces of the enclosure structure to adjust the indoor temperature. The radiation air conditioner body is provided with cold and hot pipes in the enclosure structure to heat the indoor The indoor air is heated or cooled, or radiation panels are added to the ceiling or the outer surface of the wall, and floor heating sheets are laid under the ground to increase or decrease the indoor temperature. The radiation and surface cooler heat transfer ratios are automatically adjusted to adapt to the space, and the radiation heat exchange is automatically adjusted to the maximum value. The radiation air conditioner body can provide sufficient heat at a lower temperature, thereby reducing energy consumption. In addition, the radiation air conditioner transfers heat through building surfaces such as walls, floors or ceilings, avoiding cold wind blowing directly on the human body, and can provide a more uniform and comfortable indoor environment (the above is an existing mature technology and this application will not repeat it).

[0023] Figure 1 , 2 As shown in Figure 3, in the present invention, the specific application of the radiation air conditioning body includes the following process. Step (1) After the staff installs the outdoor system 4 and the indoor unit 1 in place, the inlet pipes of the booster water pumps M of the multiple indoor units 1 are connected to the outlet pipes 41 of the outdoor system through a pipeline, the first outlet end of the electric proportional valve M1 and the inlet pipe of the indoor transducer 2 (floor heating plate or radiation plate) are fixedly connected through a pipeline, the outlet pipe of the transducer 2 and the first end of a three-way pipe 3 are connected through a pipeline, and the second and third ends of the three-way pipe 3 are respectively connected to the second outlet end of the electric proportional valve M1 and the return pipe 42 of the outdoor system through a pipeline, so that the multiple indoor units are connected in parallel and connected in parallel with the outdoor system through pipelines; through the above, the transducer 2 and the indoor unit 1 do not need to be separately connected in parallel with the outlet pipe 41 of the outdoor system 4 through pipelines, which saves the number of pipelines, reduces the installation workload, and improves safety and efficiency. In step (2), when the booster pump M1 is working, the cold water or hot water input from the outdoor system is pumped into the surface cooler 101 and the energy conversion plate 2 under pressure. After heat dissipation or refrigeration, the heat medium or refrigerant flows back into the outdoor system for recycling and reuse. In this step, since the water pressure is increased by the booster pump, it can prevent the pipeline connecting the outdoor system 4 and the indoor unit 1 from being too long, causing the indoor room at the end of the pipeline to be unable to effectively obtain the cold or hot medium supply, which has an adverse effect on its cooling or heating, and the pipeline is relatively short, causing excessive pressure in the pipeline, resulting in unnecessary waste of electric energy.

[0024] Figure 1 , 23, in step (3), after the AC power enters the power input terminal of the power module A5, the control system A1, and the electric proportional valve M1, the above-mentioned mechanisms are powered on and work (the control system A1 controls the ultraviolet sterilization lamp and is powered on and works at the same time), the power module A5 outputs a DC 24V power supply to the power input terminal of the humidity sensor A3 and the two sets of temperature sensors A21 and A22. The humidity sensor A3 and the two sets of temperature sensors A21 and A22 respectively detect the humidity data, indoor temperature data and the outlet pipe temperature data of the booster water pump M in real time, and output them to the control system A 1's three-way signal input terminals 13, 11, and 12 (the greater the humidity or temperature data, the higher the signal voltage or current entering the control system A1, and vice versa); two sets of temperature sensors and humidity sensors respectively collect the indoor temperature, the outside temperature of the booster water pump outlet, and the indoor temperature data in real time, and then output the current signal that changes dynamically with the temperature and humidity to the PLC (control system A1) signal input terminal. The control system A1 controls the operating frequency of the booster pump M and the fan F, as well as the valve core opening of the electric proportional valve M1 according to the size of the input signal. In the heating mode of the outdoor unit system, when the indoor temperature is low and the humidity is high, the control system A1 controls the booster pump (the operating frequency becomes higher, the output power becomes larger, and the amount of liquid medium pumped into the surface cooler becomes larger) and the fan (the operating frequency becomes higher, the output power becomes larger, the amount of air sucked in by negative pressure becomes larger, and the higher the heat blown out by the air), the operating frequency becomes higher, and more heat medium is provided to the surface cooler and the transducer. The amount of hot air blown out by the fan blades is larger, the indoor temperature rises, and the humidity decreases (in this mode, the control system outputs a higher control current signal to control the electric proportional valve M1, the valve core of the first liquid outlet end of the electric proportional valve M1 is opened to a large extent, and the liquid medium flow entering the transducer is relatively large, and the liquid medium flow through the second liquid outlet is relatively large. When the indoor temperature is high and the humidity is low, the control system A1 controls the working frequency of the booster pump (the working frequency becomes lower, the output power becomes smaller, and the amount of liquid medium pumped into the surface cooler becomes smaller) and the fan (the working frequency becomes lower, the output power becomes smaller, the amount of air drawn in by negative pressure becomes smaller, and the heat blown out by the air is reduced). Less heat medium is provided to the surface cooler and the energy conversion plate, and the amount of hot air blown out by the fan blades is smaller, the indoor temperature is reduced, and the humidity remains unchanged (in this mode, the control system outputs a lower control current signal to control the fan speed until it stops, the water pump speed becomes lower, and the liquid medium entering the system is reduced, and the temperature and humidity of the space are constant).In the cooling mode of the outdoor system, when the indoor temperature and humidity are high, the control system A1 controls the booster pump (the operating frequency becomes higher, the output power becomes larger, and the amount of liquid medium pumped into the surface cooler becomes larger) and the fan (the operating frequency becomes higher, the output power becomes larger, the amount of air sucked in by the negative pressure becomes larger, and the higher the cooling capacity of the air blown out), the operating frequency becomes higher, and more refrigerant is provided to the surface cooler, and the amount of cold air blown out by the fan blades is larger. When the indoor temperature drops and the temperature of the A22 pipe is higher than the dew point temperature (in this mode, the control system outputs a higher control current signal to control the opening degree of the valve core of the first liquid outlet end of the electric proportional valve M1, the liquid medium flow entering the transducer is relatively large, and the amount of liquid medium directly output to the return pipe of the outdoor system through the second liquid outlet end becomes larger. Small); when the indoor temperature is low and the humidity is low, the control system A1 controls the booster pump (the operating frequency becomes lower, the output power becomes smaller, and the amount of liquid medium pumped into the surface cooler becomes smaller) and the fan (the operating frequency becomes lower, the output power becomes smaller, the amount of air sucked in by the negative pressure becomes smaller, the less cold air blown out, the lower the cold air blown out) to reduce the operating frequency, provide less refrigerant for the surface cooler and the transducer, and the amount of cold air blown out by the fan blades is smaller, the indoor temperature rises, and the humidity becomes higher (in this mode, the control system outputs a lower control current signal to control the first liquid outlet end valve core of the electric proportional valve M1 to open a small degree, the liquid medium flow entering the transducer is relatively small, and the amount of liquid medium directly output to the return pipe of the external system through the second liquid outlet becomes larger). In this step, it can prevent the control of indoor temperature and humidity based on the temperature and humidity sensor data signal of the external system, and there are deviations in each indoor area, and there are also deviations in the temperature and humidity of different rooms. The unified mode cannot effectively meet the temperature and humidity adjustments of each room, and cannot bring a better user experience to the user.

[0025] Figure 1 , 2 As shown in FIG. 3 , in step (4), when the indoor unit 1 is working, the external air enters the rear end of the cooler through the ventilation grooves 103 on both sides of the rear end of the shell under the negative pressure generated by the fan F, and the flowing air passes through the plurality of fins at the rear end of the cooler 101 and the front end of the cooler 101 to dissipate heat or cold, and then outputs hot air or cold air to the indoor environment through the filter 104 at the front end of the shell. At the same time, a plurality of ultraviolet germicidal lamps H disinfect the air entering the room. In this step, since the fan is installed on the inner side of the V-shaped cooler 101, the cooler 101 encloses the fan M to reduce external noise, and the light of the ultraviolet germicidal lamp H is blocked by the V-shaped cooler to reduce the adverse effects of light leakage on the user's health.

[0026] Figure 1 , 2As shown in Figure 3, through all the above technical solutions, the present invention integrates multiple indoor equipment together with a compact structure. The indoor and outdoor systems installed in each room are connected in parallel through pipes, and the indoor unit and the transducer in each room are connected in series through pipes. During installation, the staff only needs to connect the corresponding two interfaces of the outdoor system with the two interfaces of the indoor unit, which can achieve quick installation, improve installation speed and efficiency, and save installation costs. Each indoor unit is equipped with a booster pump. The sensors equipped with the control system of each indoor unit can collect the temperature, humidity and pipeline temperature of each room in real time. The indoor temperature and humidity data and the flow rate of the booster pump are accurately adjusted through a one-position two-way proportional valve, which can relatively achieve accurate temperature and humidity control, thereby providing users in different rooms with a more comfortable experience and achieving energy-saving effects. The fan and ultraviolet sterilization lamp of the indoor unit are installed on the inner side of the V-shaped structure surface cooler, which reduces the noise of the fan, and simultaneously sterilizes and disinfects the inner ends of the two parts of the surface cooler, and reduces the adverse effects of ultraviolet leakage on the health of users. Figure 3 Among them, voltage module A5 is a finished product of AC 220V to DC 24V switching power supply module; PLCA1 model is LK2N-32MR; temperature sensors A21 and A22 are finished products of thermocouple temperature transmitter model SGN-HR, which have two power input terminals and one signal output terminal (output 4-20mA current signal); humidity sensor A3 is a finished product of humidity transmitter model KS-SHTE, which has two power input terminals and one signal output terminal (output 4-20mA current signal); booster pump M It is a variable frequency booster water pump of model SHIMGE / 220V (power 120W); the electric proportional valve M1 is a one-inlet and two-outlet electric proportional valve with a power of 5W. It has two power input terminals and one signal input terminal. When different current signals are input into the control signal input terminal, the valve core opens and closes to different degrees. When the flow rate of one liquid outlet terminal is large, the flow rate of the other liquid outlet terminal is small.

The appearance of the surface cooler is not limited to one and can be any one of the structures surrounding the fan.

5. The multifunctional radiant air conditioner according to claim 1, characterized in that: Ultraviolet germicidal lamps can also use any lamp with germicidal function.

6. The application method of a multifunctional radiant air conditioner according to any one of claims 1 to 5, characterized in that: The method comprises the following steps: S1: after the staff installs multiple sets of external machine systems and internal machines in place, the liquid inlet pipes of the booster water pumps of the multiple sets of internal machines are connected to the liquid outlet pipes of the external machine systems or the buffer water tank, and the second liquid outlet end of the electric proportional valve is connected to the liquid return pipe of the external machine system; S2: When the booster pump is working, the cold water or hot water input from the outdoor system is pumped into the cooler and the transducer. S3: Two sets of temperature sensors and humidity sensors respectively collect the indoor temperature, the tube side temperature after the outlet of the booster pump passes through the cooler, and the indoor humidity data in real time, and then output signals that change dynamically with temperature and humidity to the control system. The control system controls the working frequency of the booster pump and the fan, as well as the valve core opening of the electric proportional valve according to the size of the input signal. In the heating mode, when the indoor temperature is low and the humidity is high, the working frequency of the booster pump and the fan increases, providing more heat medium for the cooler and the transducer, and the fan blades blow out more hot air. When it is detected that the temperature of the tube surface (the output end of the cooler) is higher than the dew point temperature, the three-way proportional valve switches to the indoor radiation plate or radiation block, and forms a series mode with the cooler (to prevent misoperation in summer). When the indoor temperature is high and the humidity is low, the working frequency of the booster pump and the fan decreases, providing less heat medium for the cooler and the transducer, and the fan blades blow out less hot air at a lower operating speed. In cooling mode, when the indoor temperature and humidity are high, the working frequency of the booster pump and the fan increases, providing more refrigerant for the cooler and the transducer. The fan blades blow out a larger amount of cold air, and the three-way proportional valve switches the cooler outlet to directly send it back to the outdoor unit system, shielding the radiation plate to prevent condensation, and lowering the indoor temperature. When it is detected that the temperature of the pipe surface (the output end of the cooler) is higher than the dew point temperature, the three-way proportional valve switches the indoor radiation plate or radiation block to form a series mode with the cooler. The temperature is lower than the set temperature and the humidity is low. At the dew point, the operating frequency of the booster pump and the fan becomes smaller, providing less refrigerant for the cooler and the transducer, and the amount of cold air blown out by the fan blades is smaller; S4: When the indoor unit is working, the external air enters the rear end of the cooler through the rear end of the shell under the action of the negative pressure generated by the fan, and the flowing air passes through the multiple fins of the cooler at the rear end, releases heat or cold through the front end of the cooler, and then outputs hot air or cold air to the indoor environment through the air vents at the front end of the shell. At the same time, the ultraviolet germicidal lamp is used to disinfect the air entering the room.

7. The application method of a multifunctional radiant air conditioner according to claim 6, characterized in that: In step S1, the energy conversion plate and the indoor unit no longer need to be separately connected in parallel with the liquid outlet pipe of the outdoor unit system through pipelines, which saves the number of pipelines, reduces the installation workload, and improves safety and efficiency.

8. The application method of the multifunctional radiant air conditioner according to claim 6, characterized in that: In step S2, it can prevent the pipeline connecting the outdoor system and the indoor system from being too long, causing the indoor room at the end of the pipeline to be unable to effectively obtain the cold or hot medium supply, which has an adverse effect on its cooling or heating. It can also prevent the pipeline from being too short, causing the pressure in the pipeline to be too high, resulting in unnecessary waste of electricity. The pipeline pressure and flow debugging can be reduced, and the system pressure can be set to the lowest pressure.

9. The application method of a multifunctional radiant air conditioner according to claim 6, characterized in that: In step S3, it can prevent the indoor temperature and humidity from being controlled based on the temperature and humidity data sensor signal of the outdoor system. There are deviations in each indoor area, and there are deviations in the temperature and humidity of different rooms. The unified mode cannot effectively meet the temperature and humidity regulation of each room, and cannot bring a better user experience to the user.

10. The application method of the multifunctional radiation air conditioner according to claim 6, characterized in that: In step S4, the fan is installed on the inner side of the V-shaped surface cooler. The surface cooler acts as an enclosure for the fan to reduce external noise. The light of the ultraviolet sterilization lamp is blocked by the V-shaped surface cooler, reducing the adverse effects of light leakage on the user's health. At the same time, isothermal dehumidification can be performed, and the incoming air can be pre-cooled and sterilized by heat treatment, and then sterilized by cold and heat treatment.
