Title:
AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/097439
Kind Code:
A1
Abstract:
In a simultaneous cooling/heating mode an air-conditioning device (100) controls both the frequency of a first compressor (10b) and the flow volume of a second heat medium flowing in a second inter-heat-medium heat exchanger (13b) such that the evaporation temperature of a first cooling medium flowing in a cooling medium flow path of a first inter-heat-medium heat exchanger (15a) that cools a first heat medium, and the condensation temperature of a first cooling medium flowing in a cooling medium flow path of a first inter-heat-medium heat exchanger (15b) that heats the first heat medium, approach a target value, and such that the temperature of the first heat medium cooled by the first inter-heat-medium heat exchange (15a) that cools the first heat medium, and the temperature of the first heat medium heated by the first inter-heat-medium heat exchanger (15b) that heats the first heat medium, approach a target value.
