Problems solved by technology

In the existing air conditioning system, the outlet of the condenser 05 is connected to the inlet pipe 03 of the electronic expansion valve. When charging refrigerant, it is necessary to weld a three-way device 02 on the inlet pipe 03 first, and weld two pieces on the three-way device 02. The connecting pipe 04 is used to connect the condenser 05 and charge the refrigerant respectively. Due to the increase of the three-way device, the cost of the accessories of the system increases, the welding process increases, and the welding failure rate increases.

Abstract

The invention discloses an electronic expansion valve for an air-conditioning system and its air-conditioning system, which belongs to the technical field of refrigeration and solves the technical problems of the existing air-conditioning and refrigeration systems such as high production cost and complicated process. The electronic expansion valve of the present invention includes a valve body with an inner cavity , the valve body is connected with an inlet pipe and an outlet pipe, and the valve body is also connected with a refrigerant charging pipe communicating with the inner cavity. Embodiments of the present invention use expansion valves, usually electronic expansion valves used in air conditioning systems such as air conditioners and refrigerators.

Description

[0001] 【Technical field】 [0002] The invention relates to an electronic expansion valve for an air-conditioning system and an air-conditioning system thereof, belonging to the technical field of refrigeration. [0003] 【Background technique】 [0004] Such as figure 1 , 2 As shown, the air conditioning system in the prior art generally includes a compressor 07, a condenser 05, an evaporator 06, and an expansion valve, wherein the function of the condenser 05 is to condense and liquefy the high-temperature and high-pressure gaseous refrigerant discharged from the compressor to form a high-pressure Liquid, the expansion valve throttles and reduces the pressure of the high-pressure liquid refrigerant condensed by the condenser 05 to become a low-temperature and low-pressure vapor-liquid mixture, which enters the evaporator to vaporize and absorb heat. In the existing air conditioning system, the outlet of the condenser 05 is connected to the inlet pipe 03 of the electronic expan...
