Abstract

The invention discloses a recycling machine, and provides a full-automatic four-port recycling machine and a using method thereof. The machine is easy to operate, liquid impact can be avoided during liquid recycling, and a recycling mode and a self-cleaning mode can be automatically switched in the whole process. The technical problems that crash, motor burnout, overload protector burnout and the like are easily caused, time and labor consumption is high during operation, safety accidents are easily caused and the like because liquid impact is easily caused and the whole process is manually operated in the prior art are solved. The machine comprises a shell, and a control valve, a compressor, a condenser and a fan which are arranged in the shell, wherein recycling machine gas and liquid input ports and recycling machine gas and liquid output ports which are connected with a refrigeration system are formed on the control valve; a gas-liquid sensor is arranged at the recycling machine liquid input port; a plurality of electromagnetic valves capable of controlling the on-off of input and output pipelines of the compressor are arranged on the pipelines; and the electromagnetic valves and the gas-liquid sensor are electrically connected to a control circuit and control the on-off of the corresponding pipelines through the control circuit.

Description

technical field [0001] The invention relates to a refrigerant recovery machine, in particular to a full-automatic four-port recovery machine which can avoid liquid shock during liquid recovery and can automatically switch between recovery and self-cleaning modes throughout the process. Background technique [0002] With the strengthening of people's awareness of environmental protection and the continuous rise of refrigerant prices, refrigerant recovery machines have become increasingly popular and used, but the existing refrigerant recovery machines generally have the following problems: 1. When there is a lot of liquid refrigerant at the input port of the recovery machine, It is easy to appear the phenomenon that the connecting copper pipe shakes severely, that is, the phenomenon of liquid shock, and the phenomenon of liquid shock can easily cause crashes, motor burnout, overload protector burnout, etc., and when a large amount of liquid refrigerant enters the compressor, i...
