More Information
Summary:The invention discloses an air-conditioning refrigeration system refrigerant oil under-pressure filling device which comprises an oiler cylinder body (11), two axial ends of the oiler cylinder body are respectively connected with an oil cylinder low-pressure side connecting pipe (14) and an oil cylinder high-pressure side connecting pipe (20), and the oil cylinder low-pressure side connecting pipe (14) and the oil cylinder high-pressure side connecting pipe (20) are respectively communicated and connected with a stop valve. An oil cylinder sliding block (16) is coaxially installed in the oil feeder cylinder body (11) in a sliding mode, the oil cylinder sliding block (16) divides the interior of the oil feeder cylinder body (11) into two spaces, and an ejector pin exhaust valve (18) is installed on the side portion of the oil feeder cylinder body (11). The problem that when refrigerant oil is supplemented into a refrigerating system of an existing air conditioner device, oil can be added only after Freon in a
