Document Type and Number:
WIPO Patent Application WO/2006/087902
Kind Code:
A1
Abstract:
A use side circuit (12) and a heat source side circuit (11) are connected by connection piping (45) to form a refrigerant circuit (10), and then, in a connection piping cleaning process, a compressor (21) is operated to circulate a refrigerant in the refrigerant circuit (10). When the refrigerant is circulated in the refrigerant circuit (10), oxide formed on the inner surface of the connection piping (45) at the time of brazing in a connection piping construction process is separated. Then, the separated oxide is washed away by the refrigerant and collected on the upstream side of the compressor (21) in the heat source side circuit (11).
