AI Technical Summary
In air conditioners, existing technologies are prone to contamination or loss when extracting and refilling refrigerant and refrigeration oil, resulting in high costs and manpower consumption, and affecting after-sales maintenance time.
An oil supply structure was designed, comprising a hydraulic reciprocating device consisting of a storage tank, a drive structure, a compressor, and a solenoid valve. The device achieves rapid recovery and separation of refrigerant and refrigeration oil through the thrust of the hydraulic device and the compressor. The solenoid valve controls the on/off of the pipeline, enabling the secondary use of the refrigeration oil.
It enables rapid recovery and separate storage of refrigeration oil and refrigerant, reducing costs, minimizing manpower consumption, improving recovery efficiency, and without affecting the lifespan of the product's built-in compressor.
