Title:
REFRIGERANT RECOVERY METHOD, REFRIGERATION AIR CONDITIONING DEVICE, AND REFRIGERANT RECOVERY SYSTEM
Document Type and Number:
Japanese Patent JP2016001097
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerant recovery method capable of more efficiently performing refrigerant recovery than conventional ones.SOLUTION: A refrigerant recovery method where gas refrigerant in a refrigerant circuit of a multi-air conditioner 10 for a building is suctioned and compressed, and compressed refrigerant is condensed and recovered, includes a step of dividing the refrigerant circuit into a plurality of areas, communicating a refrigerant recovery part 21 to one of the plurality of areas and suctioning gas refrigerant. The refrigerant recovery method repeats a step of switching the area to which the refrigerant recovery part 21 is communicated and suctioning gas refrigerant from a different area from the area to which the refrigerant recovery part 21 is communicated.
