[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0032] As Figure 1-6 shown, Figure 1For the sake of easy illustration, the fresh air side and the return air side are drawn on the same side. In actual use, the return air side and the supply air side are on the same side. An efficient temperature and humidity regulating fresh air unit includes a fresh air passage and a return air passage located inside the casing 13. In the fresh air passage, there are a filter net 1, a fluorine pump system 2, an evaporator 3, a reheating coil 4, a humidifier 5 and a supply fan 8. In the return air passage, there are a filter net 1, a fluorine pump system 2, a condenser 6, a compressor 7, a supply fan 8. The fluorine pump system 2 is located between the filter net 1 and the evaporator 3. The fluorine pump system 2 includes a sprayer 2-3, a heat exchanger 2-1, a copper pipe 2-2 and a pump 2-4. A check valve 11 and a solenoid valve are connected to the reheating coil 4. An expansion valve 12 is also connected to the evaporator 3.

[0033] On both sides of the casing 13 are the air inlets 14 and air outlets 15 of the fresh air passage and the return air passage respectively. The fresh air passage is located above the return air passage. Air enters from the air inlet 14, and then is blown out from the air outlet 15 under the action of the supply fan 8.

[0034] The filter net 1 is perpendicular to the bottoms of the fresh air passage and the return air passage respectively. The supply fans 8 in the fresh air passage and the return air passage are respectively located at the positions of the air supply inlet and the air discharge outlet. The filter net 1 first plays a role in filtering the gas entering the casing 13, preventing impurities and particles in the air from entering the inside of the casing 13 and causing damage to the inside of the casing 13.

[0035] The heat exchanger includes an upper heat exchanger 2-11 and a lower heat exchanger 2-12. A copper pipe 2-2 is provided between the upper heat exchanger 2-11 and the lower heat exchanger 2-12 of the fluorine pump system 2. A pump 2-4 is provided between the outsides of the heat exchangers. The refrigerant in the copper pipe 2-2 is transferred from the lower heat exchanger 2-12 at the bottom to the upper heat exchanger 2-11 at the top of the copper pipe 2-2 by the pump 2-4. The lower heat exchanger 2-12 at the bottom of the copper pipe 2-2 is located on the bottom of the casing 13. A spray head 2-3 is provided on the lower heat exchanger 2-12 located at the bottom of the casing 13. The spray head 2-3 sprays towards the copper pipe 2-2 for cooling. The water sprayed by the spray head 2-3 is provided externally. The spray cools the refrigerant in the copper pipe 2-2, making it become a low-temperature liquid again. The fluorine pump pumps the liquid refrigerant back upwards. Fluorine forms a cycle in the coil, releases heat and liquefies at the bottom and rises to the top. A spray system 2 is provided at the top to cool the fluorine, enabling it to absorb more heat. It vaporizes into a gas and is pumped back to the bottom by the pump 2-4, thus completing a cycle.

[0036] When the fluorine pump system 2 processes fresh air, it can first perform preliminary cooling on the fresh air, thereby reducing the refrigeration capacity of the compressor, lowering energy consumption. Moreover, the fluorine pump system contains spray water. When the water pump is turned on, it cools the refrigerant in the copper pipe 2-2, causing it to liquefy, and then pumps it back up through the pump for recycling. The structure is also designed with a reheating coil 4 and an evaporative condensing system. The evaporative condenser releases heat, and part of the released heat returns to the reheating coil 4 to further heat the supply air, making use of the heat recovery technology, increasing the energy utilization rate. At the same time, the unit is integrated, reducing the outdoor unit part of the air conditioner, greatly reducing its floor area, achieving cost reduction in manufacturing materials, and reducing the occupation of public places.

[0037] The evaporator 3 is connected to the reheating coil 4, the condenser 6, and the compressor 7 through the copper pipe 2-2. A temperature sensor is also connected to the condenser 6 to monitor the condensation temperature. When the condensation temperature exceeds the preset value, the spray pump 16 on the condenser side starts to spray the condenser 6, allowing the high-temperature and high-pressure gas in the condenser 6 to become a low-temperature and high-pressure gas-liquid mixture through exhaust air and spray water, reducing the condensation temperature of the condenser and enabling the system to operate normally. There is a spray pump 16 between the condenser 6 and the compressor 7, and the spray pump 16 is supplied with water externally. The evaporative cooling and heat dissipation system uses the physical phenomenon of water evaporation to absorb heat for refrigeration, with advantages such as energy conservation and environmental protection, and high energy efficiency.

[0038] One end of the expansion valve 12 is connected between the evaporator 3 and the check valve 11, and the other end of the expansion valve 12 is located between the evaporator 3 and the compressor 7. The compressor 7 is connected to the condenser 6, the expansion valve 12, and the evaporator 3. The expansion valve 12 reduces the pressure and throttles the normal-temperature and high-pressure refrigerant liquid into a low-temperature and low-pressure liquid.

[0039] The reheating coil 4 is respectively connected to one end of the check valve 11 and one end of the solenoid valve a9. The other end of the solenoid valve a10 is connected between the condenser 6 and the solenoid valve b10. The other end of the check valve 11 is also connected to the solenoid valve a9. The condenser 6 is connected to the compressor 7. When the reheating coil 4 needs to be opened, the solenoid valve a9 is opened and the solenoid valve b10 is closed. When the reheating coil 4 is not needed, the solenoid valve a9 is closed and the solenoid valve b10 is opened.

[0040] Working principle: Air enters from the air inlet 14 of the casing 13, passes through the filter net 1, and then passes through the fluorine pump system 2. After passing through the fluorine pump system 2, when dealing with fresh air, the fluorine pump system 2 can first conduct preliminary cooling treatment on the fresh air, thereby reducing the refrigerating capacity of the compressor 7 and lowering the energy consumption. Moreover, the fluorine pump system 2 contains spray water. When the water pump is turned on, it cools the refrigerant in the copper pipe 2-2 to make it liquefy, and then pumps it to the upper part through the pump for recycling. The evaporator 3 evaporates and condenses to release heat, and part of the released heat returns to the reheating coil 4 to further heat the air supply. The humidifier 5 cools the reheating coil 4, and then it is sent out from the air outlet 15 through the air supply fan 8;

[0041] In the return air channel, air enters the casing 13 from the return air inlet 14 through the filter net 1, then passes through the fluorine pump system 2 and then passes through the condenser and is discharged from the air outlet of the air outlet.

The object of the present invention has been completely and effectively achieved. The function and structural principle of the present invention have been demonstrated and explained in the embodiments. Without departing from the said principle, the embodiments of the present invention can have any deformation or modification.
