Title:
REFRIGERANT CIRCULATION DEVICES, REFRIGERANT CIRCULATION METHOD, REFRIGERANT-FILLING METHODS, AND METHOD FOR OPERATING REFRIGERANT CIRCULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/158822
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide refrigerant circulation devices and a refrigerant circulation method which are capable of inhibiting a refrigerant comprising a hydrofluoroolefin (HFO) or hydrochlorofluoroolefin (HCFO) from decomposing and thereby generating an acid. One of the refrigerant circulation devices is a refrigerant circulation device (1) which includes a compressor (3), a condenser (5), expansion valves (9, 19), and an evaporator (11) that have been connected to each other by main piping (17a to 17e) to configure a refrigerant circulation circuit for circulating a refrigerant therethrough, and into which a refrigerant comprising an HFO or HCFO each having a carbon-carbon double bond in the molecular structure has been packed. The refrigerant circulation device (1) is equipped with a drive (15) for driving the compressor (3) via a speed increaser (13) and with a drive-cooling part (25) for cooling the drive (15) with the refrigerant condensed in the condenser (5), a desiccant which can trap water having been disposed in the evaporator (11) or the drive-cooling part (25).
