Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/172135
Kind Code:
A1
Abstract:
This air conditioning device (100) is provided with: a heater (22) that uses heat from a refrigerant compressed in a compressor (21) to heat air guided into a vehicle cabin; a liquid receiver (24) that is arranged downstream of an exterior heat exchanger (23) and that separates the refrigerant guided from the exterior heat exchanger (23) into a gas-phase refrigerant and a liquid-phase refrigerant and stores the liquid-phase refrigerant; and a throttle mechanism (27) that is provided between the heater (22) and the exterior heat exchanger (23) and causes the refrigerant to be depressurized and expanded. When there is a dehumidifying request, a dehumidifying and heating mode, in which the refrigerant is evaporated by an evaporator (25) and heat radiation is performed with the heater (22) while the flow of the refrigerant is throttled by the throttle mechanism (27), is temporarily switched to a cooling mode in which the refrigerant is evaporated by the evaporator (25) and storage of the liquid-phase refrigerant in the liquid receiver (24) is accelerated while the flow of the refrigerant is not throttled by the throttle mechanism (27).
