[0029] Example

[0030] See also Figure 1-4The present invention provides a technical solution: an air-cooled cold water precision air-conditioning system, comprising a frame 1, a compressor 2 is installed inside the frame 1, an air-cooled condenser 4 is installed inside the frame 1 on one side of the compressor 2, a condensing fan 5 is installed inside the frame 1 on one side of the air-cooled condenser 4, an air outlet net 6 is arranged at one end of the frame 1 on the outside of the condensing fan 5, a throttling electronic expansion valve 7 is installed inside the frame 1 on one side of the compressor 2, and a water-cooled evaporator 8 is installed inside the frame 1 above the throttling electronic expansion valve 7. Under the refrigeration working environment temperature, the high-temperature and high-pressure refrigerant gas discharged from the outlet of the compressor 2 flows through a number of copper tubes and then enters the air-cooled condenser 4 for condensation and heat release. At the same time, the condensing fan 5 forces the refrigerant in the air-cooled condenser 4 to exchange heat with the air through convection. The liquid refrigerant after condensation and heat release is throttled, depressurized and cooled through the throttling electronic expansion valve 7. The low-temperature and low-pressure liquid refrigerant after throttling evaporates in the water-cooled evaporator 8 by absorbing the heat of water in the plate heat exchanger, thereby realizing refrigeration. The low-temperature and low-pressure refrigerant gas flowing out of the water-cooled evaporator 8 is sucked in and compressed by the compressor 2, and the refrigerant compressed by the compressor 2 is discharged through the exhaust port of the compressor 2, thus completing a refrigeration cycle;

[0031] An electric control board 10 is installed on the top of the water-cooled evaporator 8 inside the frame 1, an expansion tank 11 is installed on the right side of the water-cooled evaporator 8 inside the frame 1, a water outlet 12 and a water inlet 13 are installed above the other end of the frame 1, and an electric heating pipe 14 is installed on the other end of the frame 1. The electric heating pipe 14 is turned on in winter or when the temperature is low to adjust the water temperature and ensure that the circulating water pump 18 delivers a constant water temperature to the liquid cooling plate 23 for the new energy storage battery. A filter 15 is installed on one side of the electric heating pipe 14 inside the frame 1. The other end of the frame 1 is provided with an air inlet net 16 below the water outlet 12 and the water inlet 13, and the other end of the frame 1 is provided with a liquid injection port 17 below the air inlet net 16. A circulating water pump 18 is installed on the inner bottom side of the frame 1. The normal temperature air around the air-cooled cold water precision air conditioner first cools the electric control board 10 after passing through the air inlet net 16, and then cools the air-cooled condenser 4 after cooling the air-cooled electric control board 10 of the air-cooled cold water precision air conditioner. After cooling the air-cooled condenser 4, the high-temperature hot air is forced to flow through the condensing fan 5 and discharged through the air outlet net 6 of the air-cooled cold water precision air conditioner. The main purpose of the air circulation is to cool the air-conditioning electric control board 10 and cool the air-cooled condenser 4, so that the high-temperature and high-pressure gas refrigerant in the air-cooled condenser 4 is condensed into medium-temperature and high-pressure refrigerant in disguised form; the water outlet 12 and the water inlet 13 are connected to a heat dissipation component through a pipeline, and a fixed component is installed on the heat dissipation component.

A water inlet pipe 25 is arranged on one side of the pipe, and a water outlet pipe 26 is arranged on the other side of the pipe. The liquid cooling plate 23 is attached to the outer side of the energy storage battery body 20. Cold water is passed through a circulating water pump. After being discharged from the drain port 18, the water enters the water-cooled evaporator 8 through several stainless steel water pipes to exchange heat with the refrigerant. The water temperature of the water-cooled evaporator 8 is further reduced. The low-temperature cold water passes through the electric heating tube 14 and is discharged through the water outlet 12. The low-temperature cold water from the water outlet 12 enters the flow channel of several liquid cooling plates 23 through the water inlet pipe 25, and is used to cool several energy storage battery bodies 20. The cold water flowing out of several liquid cooling plates 23 is discharged through the water outlet pipe 26. The cold water passes through the water inlet 13 and the filter 15 and then enters the water inlet of the circulating water pump 18. Another part of the water is stored in the expansion tank 11 to stabilize the water cooling pressure. After being discharged from the drain port of the circulating water pump 18, the cold water enters the water-cooled evaporator 8 to exchange heat with the refrigerant, realizing a water circulation cycle, that is, cold water. The injection port 17 is used to add water to the water system.

[0034] Working principle or structural principle, under the refrigeration working environment temperature, the high-temperature and high-pressure refrigerant gas discharged from the outlet of the compressor 2 flows through several copper tubes and enters the air-cooled condenser 4 to condense and release heat. At the same time, the condensing fan 5 forces the refrigerant in the air-cooled condenser 4 to exchange heat with the air through convection. The liquid refrigerant after condensation and heat release passes through the throttling electronic expansion valve 7 to reduce pressure and temperature. The throttled low-temperature and low-pressure liquid refrigerant in the water-cooled evaporator 8 absorbs the heat of the water in the plate heat exchanger and evaporates to achieve refrigeration. The low-temperature and low-pressure refrigerant gas flowing out of the water-cooled evaporator 8 is sucked in and compressed by the compressor 2, and the refrigerant compressed by the compressor 2 is discharged through the exhaust port of the compressor 2 to achieve a refrigeration cycle.

[0035] At the refrigeration working environment temperature, the cold water is discharged from the water outlet of the circulating water pump 18 and then enters the water-cooled evaporator 8 through several stainless steel water pipes to exchange heat with the refrigerant. The water temperature of the water-cooled evaporator 8 is further reduced, and the low-temperature cold water is discharged from the water outlet 12 after passing through the electric heating tube 14. The low-temperature cold water from the water outlet 12 enters the flow channel of several liquid cooling plates 23 through the water inlet pipe 25, and is used to cool several energy storage battery bodies 20. The cold water flowing out of several liquid cooling plates 23 is discharged through the water outlet pipe 26. The cold water passes through the water inlet 13 and the filter 15 and then enters the water inlet of the circulating water pump 18. Another part of the water is stored in the expansion tank 11 to stabilize the water cooling pressure. The cold water is discharged from the water outlet of the circulating water pump 18 and then enters the water-cooled evaporator 8 to exchange heat with the refrigerant, realizing a water circulation cycle, that is, cold water. The injection port 17 is used to add water to the water system.

[0036] The normal temperature wind around the air-cooled cold water precision air conditioner first cools the electric control board 10 after passing through the air inlet network 16, and then cools the air-cooled condenser 4 after cooling the air-cooled air-cooled cold water precision air conditioner electric control board 10. After cooling the air-cooled condenser 4, the high temperature hot air is discharged through the air-cooled cold water precision air conditioner outlet network 6 by forced convection of the condensing fan 5. The main purpose of the air circulation is to cool the air-conditioning electric control board 10 and cool the air-cooled condenser 4, so that the high temperature and high pressure gas refrigerant in the air-cooled condenser 4 is condensed into medium temperature and high pressure refrigerant in disguised form. According to the refrigeration principle and refrigerant characteristics, the disadvantage of unstable temperature of cooling the energy storage battery body 20 of the existing air-cooled cold water precision air conditioning system with the same configuration is overcome, so that the energy storage battery body 20 can operate stably and reliably.

[0037] In addition, the water or cold water in the water path is: 50% ethylene glycol aqueous solution; the circulating water pump 18 pumps the water in the water path to the water-cooled evaporator 8 for cooling, and the cooled water is transported by the circulating water pump 18 to the liquid cooling plate 23 to cool the energy storage battery body 20. The electric heating tube 14 is turned on in winter or when the temperature is low to adjust the water temperature and ensure that the water temperature transported by the circulating water pump 18 to the liquid cooling plate 23 for the new energy storage battery is constant.
