Document Type and Number:
Japanese Patent JP2017072284
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the careful confirmation and attention, or the like of a recovery worker in refrigerant recovery using a refrigerant recovery device.SOLUTION: A refrigerant recovery device 60 includes: a refrigerant suction side port 62 connected to a service ports 50, 52 side for refrigerant recovery of an air conditioner 20 being a refrigerator for performing a refrigeration cycle by a cycle of refrigerant compression, condensation and evaporation; a recovery part 66 including a compressor 68 for compressing a refrigerant from the refrigerant suction side port 62 and a condenser 82 for condensing the compressed refrigerant; a refrigerant discharge side port 64 connected to a refrigerant recovery container 100 to discharge the refrigerant condensed by the recovery part 66 as a recovery refrigerant 117; and a refrigerant information output part 98 for using sensors for detecting refrigerant characteristics to output information on the recovery refrigerant. A first pressure sensor 90 for detecting condensation pressure, and a temperature sensor 92 for detecting condensation temperature are used as sensors.SELECTED DRAWING: Figure 1
