Title:
AIR CONDITIONING DEVICE
Document Type and Number:
Japanese Patent JP2023072193
Kind Code:
A
Abstract:
To provide an air conditioning device that can appropriately control a state of a refrigerant passing through a heat exchanger, realize efficient heat exchange, and improve an operation performance while downsizing the heat exchanger.SOLUTION: An air conditioning device comprises a gas-liquid separator, a first expansion valve, a second expansion valve, a third expansion valve, a first heat transfer part, and a second heat transfer part. The gas-liquid separator performs gas-liquid separation of a refrigerant. The first expansion valve is provided in a second pipe between the gas-liquid separator and an outdoor heat exchanger. The second expansion valve is provided in the second pipe between the gas-liquid separator and an indoor heat exchanger. The third expansion valve is provided in a first pipe between a four-way valve and a suction port of a compressor. The first heat transfer part is thermally connected to the first pipe between the third expansion valve and the suction port of the compressor, and is thermally connected to the second pipe between the outdoor heat exchanger and the first expansion valve. The second heat transfer part is thermally connected to a third pipe, and is thermally connected to the second pipe between the indoor heat exchanger and the second expansion valve.SELECTED DRAWING: Figure 1
