Embodiment Construction

[0009] As attached figure 1 As shown, the vehicle air conditioner pressure adjusting device of the present invention is composed of pipeline gas flow direction control, gas recovery and storage, and refrigerant charging parts, and is characterized in that: the pipeline gas flow direction control part includes a low pressure quick connector (1), high pressure quick connector (2), high pressure meter (3), low pressure meter (4), pipeline (5), pipeline (6), high pressure side solenoid valve (7), front recovery solenoid valve (8) And then recover the solenoid valve (9); the high-pressure quick connector (2) is connected to one end of the pipeline (5) through threads and rubber seals, and the middle of the pipeline (5) is connected with the high-pressure meter (3) through pipe threads. The other end of the circuit (5) is connected to the inlet of the high-pressure solenoid valve (7) through a copper sodium and a bell mouth. The low-pressure quick connector (1) is connected to one end...

Abstract

The invention relates to the technical field of air conditioners, and in particular relates to a pressure adjustment device for a vehicle air conditioner. The device consists of a pipeline gas flow direction control part, a gas recovery and storage part and a refrigerant filling part. The pressure adjustment device provided by the invention freely adjusts working pressure of the vehicle air conditioner, and also has simple adjustment steps and high efficiency; when the working pressure of the vehicle air conditioner is low, refrigerant is not recovered completely during adjustment, and then vacuumizing, oiling and refrigerant refilling are performed, so that time and resources are saved; and when the working pressure of the vehicle air conditioner is high, refrigerant is not discharged during adjustment to avoid resources wasting and environmental pollution.

Description

Technical field [0001] The present invention relates to the technical field of vehicle air conditioners, in particular to a vehicle air conditioner pressure adjusting device. Background technique [0002] When the vehicle air-conditioning refrigeration system is operating, the system can be divided into two parts, high pressure and low pressure. The part between the evaporator and the compressor suction port is called the low pressure part; the part between the compressor discharge port and the condenser is called High voltage part. Both high-voltage and low-voltage parts have corresponding standard service interfaces. If the air conditioning system is operating normally, the pressure values ​​of the high and low pressure parts are relatively stable. If the pressure values ​​of the high pressure and low pressure parts are different from the normal values, it means that there is a problem with the system or the R134a refrigerant. In other words, when a vehicle air conditioner f...
