Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/069666
Kind Code:
A1
Abstract:
This air conditioning device (100) is provided with: a compressor (21); an outdoor heat exchanger (23); an evaporator (25) for evaporating a refrigerant by allowing the refrigerant to absorb the heat of air conducted to the interior of a vehicle; a heater (42) by which the air, which is conducted to the interior of the vehicle, is heated using the heat of a refrigerant compressed by the compressor; a liquid receiver (24) which is disposed downstream of the outdoor heat exchanger (23), separates a refrigerant conducted from the outdoor heat exchanger (23), into a liquid-phase refrigerant and a gas-phase refrigerant, and holds the liquid-phase refrigerant; and a throttle mechanism (27) which is provided between the heater (42) and the outdoor heat exchanger (23) and by which a refrigerant is expanded by pressure reduction. In an operating state in which the flow of a refrigerant is throttled by the throttle mechanism (27) and heat is radiated by the heater (42), switching is performed between a first operating mode in which the liquid-phase refrigerant is held in the liquid receiver (24) and the gas-phase refrigerant is conducted to the compressor (21), and a second operation mode in which the liquid-phase refrigerant held in the liquid receiver (24) is conducted to the evaporator (25).
