Title:
FREEZING APPARATUS INSTALLATION METHOD AND FREEZING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2005/038360
Kind Code:
A1
Abstract:
A freezing apparatus having a structure enabling separation and removal of an incondensable gas in a refrigerant circuit by using a separation film, the gas being the gas having been left in refrigerant connection piping in a field installation and being in the refrigerant circuit in a state mixed with a refrigerant. In the apparatus, separation efficiency at the separation film of the incondensable gas is enhanced. An air conditioner (1) has a refrigerant circuit (10) constituted by connecting a heat source unit (2) and a utilization unit (5) through refrigerant connecting piping (6, 7), a cooler (32), a sub-receiver (33), and a separation film device (34). The cooler (32) operates a compressor (21) to circulate a refrigerant in the refrigerant circuit (10), cooling at least a part of the refrigerant flowing in the liquid side refrigerant circuit (11). The sub-receiver (33) separates the refrigerant cooled by the cooler (32) into both a gas refrigerant containing an incondensable gas and a liquid refrigerant. The separation film device (34) has a separation film (34b) for separating the incondensable gas from the separated gas refrigerant, and the separated incondensable gas is discharged to the outside of the refrigerant circuit (10).
