Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/023894
Kind Code:
A1
Abstract:
Disclosed is an air-conditioning device (1) having a bypass refrigerant pipe (26) that branches off a portion of a refrigerant condensed by an external heat exchanger (23) during a refrigeration operation to return the portion to the intake side of a compressor (21), and a super-cooling heat exchanger (25) that cools the refrigerant condensed by the external heat exchanger (23) by means of the refrigerant flowing through this bypass refrigerant pipe (26). The device is capable of performing super-cooling degree control, which controls a device which configures the heat-source unit, such that the super-cooling degree of the refrigerant at the outlet of the external heat exchanger (23) is close to a target super-cooling degree.
