Abstract

The invention provides a portable refrigerant recycling machine and a refrigerant recycling system. The portable refrigerant recycling machine comprises a compressor, a throttling device, a condenserand a recycling barrel. An outlet of the compressor is connected with an inlet of the condenser, an outlet of the condenser is connected with an expansion valve of the throttling device, an outlet ofthe expansion valve is connected with the refrigerant recycling barrel, and the refrigerant recycling barrel is connected with an air return valve and connected with an air inlet of the compressor again. The air inlet of the compressor is provided with two air return ports, one end is connected with a to-be-recycled refrigerant connector, and the other end is connected with an outlet of the air return valve of the recycling barrel. By means of the portable refrigerant recycling machine, the recycling efficiency of a refrigerant can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a portable refrigerant recovery machine and a refrigerant recovery system. Background technique [0002] In order to protect the ozone layer and improve the living environment of human beings, government agencies around the world have issued policies that must not discharge ozone-depleting substances (mainly CFCs and HCFCs) into the atmosphere in refrigeration and air-conditioning devices. The recycling and reuse of refrigerants has become an inevitable choice for development. For this reason, a refrigerant recovery machine for recycling and reusing refrigerants has been specially developed in the society. [0003] However, the container used by existing refrigerant recovery machines for storing and recovering refrigerant is a closed recovery barrel. For example, when Freon is recovered, the gas-liquid mixture of Freon will expand and absorb heat in the recovery barrel to b...
