Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/002153
Kind Code:
A1
Abstract:
In the present invention a refrigerant circuit (11) is equipped with a heat-source-side heat exchanger (22), a supercooling heat exchanger (50), and multiple usage-side heat exchangers (31a-31d). The refrigerant circuit (11) is capable of executing a combined operation in which the heat-source-side heat exchanger (22), functioning as a radiator, usage-side heat exchangers functioning as evaporators, and usage-side heat exchangers functioning as radiators are combined. During the combined operation the supercooling heat exchanger (50) combines and cools the refrigerant flowing from all of the heat exchangers functioning as radiators (22, 31b, 31d), and supplies the cooled refrigerant to all of the heat exchangers functioning as evaporators (31a, 31c). Only the refrigerant cooled by the supercooling heat exchanger (50) flows to the usage-side heat exchangers functioning as evaporators.
