Refrigeration apparatus constructing method, and refrigeration apparatus

摘要

A refrigeration apparatus utilizes a separation membrane to separate and eliminate a noncondensable gas from a refrigerant inside a refrigerant circuit. The refrigeration apparatus has a gas separation apparatus. The gas separation apparatus includes a separation membrane apparatus connected to a liquid side refrigerant circuit that connects a heat source side heat exchanger and a utilization side heat exchanger. The separation membrane apparatus has a separation membrane that separates from the refrigerant and discharges out of the liquid side refrigerant circuit the noncondensable gas remaining in a refrigerant connecting pipe.
