Recycling and filling machine for automobile air conditioner refrigerant and application thereof

Abstract

The invention discloses a recycling and filling machine for an automobile air conditioner refrigerant and application of the recycling and filling machine. The machine comprises a high-low pressure connector, a high-low pressure valve group, a confluence valve block, an expansion valve, a heat exchange oil separator, a drying filter, a compression mechanism and a working tank. The recycling and filling machine is connected with an automobile air conditioner through the high-low pressure connector. The high-low pressure connector, the high-low pressure valve group, the confluence valve block, the expansion valve and the heat exchange oil separator are connected in sequence, the heat exchange oil separator is further connected with the drying filter and the compression mechanism in sequence,and the compression mechanism is connected with the heat exchange oil separator and the working tank. According to the recycling and filling machine for the automobile air conditioner refrigerant andapplication of the recycling and filling machine, the structure is simple, recycling, purifying and filling of the refrigerant are integrated, resources are not wasted, no potential threat is causedto global climate warming, device stability is good, the failure rate is low, and the application range is wide.
