Title:

AIR CONDITIONING DEVICE, AIR CONDITIONING METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2018/037545

Kind Code:

A1

Abstract:

An air conditioning device (100) operates in an operating mode selected from a first cooling mode, a second cooling mode, and a dehumidifying mode. The air conditioning device (100) comprises a refrigerant circuit (102) in which a refrigerant circulates through, in order, a compressor (111), an outdoor heat exchanger (113), a first expansion valve (115), a first indoor heat exchanger (121), a second expansion valve (123), and a second indoor heat exchanger (122). In the first cooling mode, the refrigerant evaporation temperature for the first indoor heat exchanger (121) is equal to the refrigerant evaporation temperature of the second indoor heat exchanger (122). In the second cooling mode, the refrigerant evaporation temperature of the first indoor heat exchanger (121) is higher than the refrigerant evaporation temperature of the second indoor heat exchanger (122) and lower than the temperature of the air in an indoor space to be air conditioned. In the dehumidifying mode, the refrigerant evaporation temperature of the first indoor heat exchanger (121) is higher than the temperature of the air in the indoor space.
