Patent ID: 7357002

Claim:
A method for installing a refrigeration device comprising: forming a refrigerant circuit by connecting a heat source unit having a compressor and a heat-source-side heat exchanger to a utilization unit having a utilization-side heat exchanger via a refrigerant connection pipe; and performing a non-condensable gas discharge operation comprising operating said compressor, recirculating refrigerant through said refrigerant circuit, cooling and separating at least a portion of the refrigerant that flows between said heat-source-side heat exchanger and said utilization-side heat exchanger into a liquid refrigerant and a gas refrigerant that includes a non-condensable gas remaining in said refrigerant connection pipe, separating said non-condensable gas using a separation membrane from said gas refrigerant obtained by gas-liquid separation, and discharging said non-condensable gas outside of said refrigerant circuit.
