In a cooling cycle that has an expansion valve 6 that performs throttle expansion and an evaporator 7 that cools the air by exchanging heat between air and refrigerant, these are connected by refrigerant conduits 8, 8a, and 8b, and can be freely attached and detached. an inlet refrigerant conduit 21 connected to the refrigerant conduit 8a downstream of the condenser 4 via a connecting portion 24a; and an outlet connected to the refrigerant conduit 8b upstream of the expansion valve 6 via a detachable connecting portion 24b. The side refrigerant conduit 22 is connected to the liquid tank 5a.
and connect the refrigerant conduit 21 to the inlet side refrigerant conduit 21.
A valve 23 is provided to open and close the refrigerant conduit 22, and an adjustment valve 25 is provided in the outlet side refrigerant conduit 22 to open and close the conduit 22 to adjust the flow rate. The recovery tank 20 containing the refrigerant condensed in the condenser 4 is used as the liquid tank 5a.
A refrigerant recovery device characterized by being connected to.
