[0002] The capillary radiation air-conditioning system mainly needs to handle three functions: one is capillary water temperature regulation, the second is fresh air treatment, and the third is centralized intelligent control. The general practice in the industry is to use independent equipment for capillary water temperature regulation, use independent equipment for fresh air treatment, and then use an independent control cabinet for centralized intelligent control. This not only increases the floor space occupied by equipment installation and the amount of construction work, but also increases the difficulty of construction work.

[0027] The present invention has the following advantages:

[0028] Aiming at the drawbacks that it is difficult to ensure the reliability and stability of a highly integrated system, the present invention has taken many technical means and measures to improve the stability and reliability, so as to reduce the system failure rate, reduce the later maintenance cost, and improve the comfort and user experience of the entire capillary radiation system.

[0029] The present invention patent is a device for a highly integrated radiation air-conditioning system. In addition to including a temperature control module and a capillary water supply module, the system of the present invention integrates all other devices required for the radiation air-conditioning system, including a fresh air module, a controller, etc.

[0030] The fresh air treatment equipment incorporates functions such as fresh air filtration, sterilization, heat recovery, dehumidification, humidification, and temperature regulation. Among them, dehumidification adopts pre-cooling dehumidification with a total heat exchanger, secondary dehumidification with a surface cooler, and tertiary dehumidification with a direct expansion evaporator; the capillary water supply module includes functions such as indoor water supply temperature regulation, cold and heat source selection, and constant pressure water make-up; the centralized control function of the radiant air conditioning system can include the control, operation monitoring, fault handling, and remote cloud platform monitoring and maintenance of fresh air equipment, water temperature treatment equipment, indoor temperature and humidity, and air quality monitoring equipment.

[0031] For the total heat exchanger used in pre-cooling dehumidification, taking advantage of the characteristics that during dehumidification operation of the heat recovery and temperature regulation type radiant system, the air temperature on the indoor side is lower, the humidity is smaller, and the enthalpy value is relatively small, while the outdoor fresh air side has a higher temperature, higher humidity, and higher enthalpy value. The outdoor fresh air is first subjected to total heat exchange with the indoor exhaust air, reducing the enthalpy value of the outdoor fresh air and then passing through the surface cooler and evaporator for dehumidification. This reduces the heat load of the subsequent surface cooler and evaporator for dehumidification, achieving the purpose of reducing energy consumption and improving energy consumption efficiency. Since the enthalpy values of the outdoor fresh air and the indoor exhaust air differ significantly, the total heat exchange process can achieve a high efficiency. Therefore, the fresh air dehumidification process can reduce more energy consumption and significantly improve energy consumption efficiency. In the heating season, the enthalpy values of the outdoor fresh air and the indoor exhaust air also differ significantly, and the total heat exchange process still has a high efficiency. Therefore, for the fresh air dehumidification and humidification equipment used in the heat recovery and temperature regulation type radiant system, adding a pre-stage total heat exchanger can effectively reduce the annual operating energy consumption, improve the annual operating energy consumption efficiency, and at the same time is conducive to stabilizing the inlet air conditions of the secondary dehumidification surface cooler and the tertiary dehumidification evaporator, improving the stability and reliability of the system.

[0032] A proportional two-way valve is set on the inlet pipe of the secondary dehumidification surface cooler. By controlling the water flow rate entering the surface cooler through the proportional two-way valve, the moisture content of the supply air can be kept at a relatively stable value under various dehumidification conditions, improving the stability and reliability of the system.

[0033] A finned condenser and an exhaust valve are arranged in parallel on the exhaust side. By adjusting the opening degree of the exhaust valve to increase or decrease the air volume passing through the finned condenser, the heat dissipation of the finned condenser is adjusted, and then the heat dissipation of the reheater is adjusted. The supply air temperature can be kept at a relatively stable value under various dehumidification conditions, improving the stability and reliability of the system.

[0034] The direct expansion evaporator is in the vapor compression cycle system. A four-way valve is added at the exhaust port of the compressor. When in certain specific working conditions, if the evaporator frosting causes a decrease in heat transfer efficiency, by controlling the conversion of the four-way valve to change the flow direction of the high-temperature refrigerant discharged from the compressor, the frost on the evaporator can be quickly removed and the dehumidification efficiency of the evaporator can be restored, improving both the dehumidification efficiency of the system and the stability and reliability of the system.

[0035] A fresh air valve is provided at the fresh air inlet, and a bypass air valve is provided between the return air inlet and the fresh air inlet. By controlling, the fresh air valve can be closed and the bypass air valve can be opened, so that the system can enter the return air recirculation mode when operating under specific conditions, reducing the system energy consumption. This not only improves the annual operating energy consumption efficiency of the system, but also enhances the stability and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

The specific modes are introduced in Embodiments 11-16.

[0095] Example 11

[0096] As Figure 2 shown, this example introduces the ventilation and cooling mode and the refrigeration and dehumidification mode of the system:

[0097] When the controller determines to enter the ventilation and cooling mode and the refrigeration and dehumidification mode, the fresh air valve 1 is opened, the bypass air valve 13 is closed, the supply fan 4 is started, the exhaust fan 9 is started, the ultraviolet light source 14 is started, the cold and heat source heat pump unit is started for refrigeration, the water pump 107 is started, the hot water electric valve 108 is closed, the humidification electric valve 112 is closed, the compressor 201 is started, and the four-way valve 202 is de-energized.

[0098] After the supply fan 4 is started, outdoor fresh air enters the system through the fresh air valve 1, passes through the primary high-efficiency fresh air filter 2 and the total heat exchanger 3 in sequence, and is then sucked in by the supply fan 4. After being pressurized, it is sent out, and then passes through the surface cooler 5, the evaporator 6, the reheater 7, and the humidifier 8 in sequence. Finally, it is sent to the indoor through the internal air duct of the system from the air supply outlet 407, forming a continuous fresh air treatment process. After the exhaust fan 9 is started, the indoor return air enters the system through the return air inlet 406, and after being pressurized by the exhaust fan 9, it enters the total heat exchanger 3 from the primary exhaust air filter 10. After completing the total heat exchange with the fresh air in the total heat exchanger 3, it comes out, and then passes through the fin condenser 11 and is discharged to the outdoor from the exhaust air outlet 405, completing the indoor exhaust air process.

[0099] After the compressor 201 is started, the discharged high-temperature and high-pressure refrigerant gas enters the fin condenser 11 through the four-way valve 202. Under the heat dissipation effect of the exhaust air passing through the fin condenser 11, the refrigerant completes heat release and temperature reduction and then comes out, enters the reheater 7, and exchanges heat with the fresh air passing through the reheater 7. The refrigerant realizes further heat release and temperature reduction, and condenses into a liquid and then comes out. After passing through the first filter 203, it enters the expansion valve 204. After the expansion throttling of the expansion valve 204, it becomes a low-temperature and low-pressure refrigerant gas-liquid mixture, enters the evaporator 6, and evaporates in the evaporator 6 to absorb the heat of the fresh air coming out of the surface cooler 5, and then all becomes low-temperature and low-pressure refrigerant gas. The low-temperature and low-pressure refrigerant gas coming out of the evaporator 6 passes through the four-way valve 202 again, enters the gas-liquid separator 205, and then enters the suction end of the compressor 201 and is compressed and discharged again by the compressor 201, forming a continuous refrigerant vapor compression cycle.

[0100] After the cold and heat source heat pump unit starts refrigeration, it provides 7°C chilled water, which enters the system through the heat pump outlet stop valve. After passing through the plate heat exchanger 109, a part of it enters the mixing tank 104. After completing the mixing heat exchange in the mixing tank 104, it comes out from the fourth opening (right outlet) of the mixing tank 104, and then returns to the cold and heat source heat pump unit through the heat pump return water stop valve. Another part of the chilled water coming out from the plate heat exchanger 109 enters the surface cooler 5 through a tee and the chilled water electric valve 111. After cooling and dehumidifying the fresh air in the surface cooler 5, it comes out and returns to the pipeline between the mixing tank 104 and the heat pump return water stop valve through a tee, and then returns to the cold and heat source heat pump unit together.

[0101] After the water pump 107 starts, it provides 18°C chilled water, which enters the indoor capillary tube ends through the indoor water supply stop valve. After these chilled waters complete the heat exchange at the indoor capillary tube ends, they come out from the indoor capillary tube ends, pass through the indoor water outlet stop valve, and then enter the system. After passing through the second filter 101, they enter the mixing tank 104, complete the mixing heat exchange with the chilled water coming from the cold and heat source heat pump unit in the mixing tank 104, and then return to the inlet of the water pump 107 after being adjusted by the proportional bypass valve 105.

[0102] After the ultraviolet light source 14 starts, the ultraviolet light with a specific wavelength emitted continuously irradiates the surface of the primary high-efficiency fresh air filter 2, eliminating the harmful bacteria and viruses attached to the surface of the primary high-efficiency fresh air filter 2 and purifying the air. At the same time, a photocatalyst component can also be added to release negative oxygen ions and freshen the air.

[0103] The centralized controller of the system adjusts the opening degree of the proportional bypass valve 105 according to the value of the water supply temperature sensor to achieve precise control of the indoor water supply temperature, adjusts the opening degree of the chilled water electric valve 111 according to the value of the moisture content of the supply air to achieve precise control of the supply air humidity, and adjusts the opening degree of the exhaust valve 12 according to the value of the supply air temperature to achieve precise control of the supply air temperature.

[0105] As Figure 3 shown, this embodiment introduces the refrigeration and dehumidification mode of the system:

[0106] When the controller determines to enter the refrigeration and dehumidification mode, the fresh air valve 1 closes, the bypass air valve 13 opens, the supply fan 4 starts, the exhaust fan 9 starts, the ultraviolet light source 14 starts, the cold and heat source heat pump unit starts refrigeration, the water pump 107 starts, the hot water electric valve 108 closes, the humidification electric valve 112 closes, and the compressor 201 starts, and the four-way valve 202 is de-energized.

[0107] After the supply fan 4 starts, the indoor return air enters the system through the return air inlet 406, passes through the bypass air valve 13, the primary high-efficiency fresh air filter 2, and the total heat exchanger 3 in sequence, and then is sucked by the supply fan 4, pressurized and sent out. Then it passes through the surface cooler 5, the evaporator 6, the reheater 7, and the humidifier 8 in sequence, and finally is sent to the indoor through the internal air duct of the system from the air supply outlet 407, forming a continuous process of reprocessing the return air. After the exhaust fan 9 starts, the indoor return air enters from the return air inlet 406 and exits from the exhaust outlet 405, just like in the ventilation cooling and refrigeration dehumidification modes, completing the indoor exhaust process.

[0108] After the compressor 201 starts, the refrigerant circulation is the same as in the ventilation cooling and refrigeration dehumidification modes, forming a continuous vapor compression cycle among the compressor 201, the four-way valve 202, the first filter 203, the expansion valve 204, the gas-liquid separator 205, the fin condenser 11, the reheater 7, and the evaporator 6.

[0109] After the cold and heat source heat pump unit starts refrigerating, the cold water completes a continuous cycle among the cold and heat source heat pump unit, the plate heat exchanger 109, the mixing water tank 104, and the surface cooler 5, just like in the ventilation cooling and refrigeration dehumidification modes.

[0110] After the water pump 107 starts, the cold water completes a continuous cycle among the indoor terminal capillary tubes, the mixing water tank 104, the proportional bypass valve 105, and the water pump 107, just like in the ventilation cooling and refrigeration dehumidification modes.

[0117] After the compressor 201 starts, the refrigerant cycle is the same as that in the ventilation cooling and refrigeration dehumidification modes. A continuous vapor compression cycle is formed among the compressor 201, the four-way valve 202, the first filter 203, the expansion valve 204, the gas-liquid separator 205, the fin condenser 11, the reheater 7, and the evaporator 6. Since the exhaust fan 9 is closed, the fin condenser 11 does not play a role in heat dissipation, and the reheater 7 undertakes all the heat dissipation of the refrigerant. Therefore, the indoor return air temperature after passing through the reheater 7 will increase.

[0118] After the cold and heat source heat pump unit starts refrigeration, the same as in the ventilation cooling and refrigeration dehumidification modes, the chilled water completes a continuous cycle among the cold and heat source heat pump unit, the plate heat exchanger 109, the mixing water tank 104, and the surface cooler 5.

[0119] After the ultraviolet light source 14 starts, the same as in the ventilation cooling and refrigeration dehumidification modes, it purifies and freshens the air in the return air recirculation.

[0120] The centralized controller of the system only adjusts the opening degree of the chilled water electric valve 111 according to the value of the moisture content of the supply air to achieve precise control of the supply air humidity.

[0121] Embodiment 14

[0124] After the ultraviolet light source 14 starts, the same as in the ventilation cooling and refrigeration dehumidification modes, it purifies and freshens the air in the return air recirculation.

[0125] After the supply fan 4 starts, the same as in the ventilation cooling and refrigeration dehumidification modes, the outdoor fresh air enters the system through the fresh air valve 1 and is sent to the room from the supply air outlet, forming a continuous fresh air treatment process. After the exhaust fan 9 starts, the same as in the ventilation cooling and refrigeration dehumidification modes, the indoor return air enters the system through the return air inlet and is discharged to the outside through the exhaust air outlet, completing the indoor exhaust process.

[0126] Embodiment 15

After passing through the plate heat exchanger 109, a part of it enters the mixing tank 104. After completing the mixing heat exchange in the mixing tank 104, it comes out from the right outlet of the mixing tank 104 and returns to the cold and heat source heat pump unit through the heat pump return water stop valve. Another part of the cold water coming out of the plate heat exchanger 109 enters the surface cooler 5 through a tee and a cold water electric valve 111. After heating the fresh air in the surface cooler 5, it comes out and returns to the pipeline between the mixing tank 104 and the heat pump return water stop valve through a tee, and then returns to the cold and heat source heat pump unit together.

[0131] After the hot water electric valve 108 opens, the municipal hot water enters the system through the hot water supply stop valve, enters the plate heat exchanger 109 through the hot water electric valve 108, exchanges heat with the hot water sent by the cold and heat source heat pump unit in the plate heat exchanger 109, and then exits the system from the third opening (left outlet) of the plate heat exchanger 109 and returns to the municipal hot water pipeline through the hot water return stop valve.

[0133] After the humidifying electric valve 112 opens, the water coming from the water softener enters the system through the soft water stop valve, enters the humidifier 8 through the humidifying electric valve 112, humidifies the hot air sent from the surface cooler 5 in the humidifier 8, and the remaining water after humidification is discharged out of the system from the drainage tray of the system through the drain pipe.

[0134] After the ultraviolet light source 14 is started, like the ventilation cooling and refrigeration dehumidification modes, it purifies and freshens the recirculated return air.
