Abstract
A refrigeration cycle apparatus includes a compressor, a four-way valve, an outdoor heat exchanger, an expansion valve, a gas-liquid separator, an indoor heat exchanger, and a refrigerant pipe that connects these components. The gas-liquid separator and a suction side of the compressor are connected by a bypass pipe. The refrigerant pipe includes a riser pipe, a curved pipe, and a down pipe sequentially connected from an upstream side to a downstream side of a flow of refrigerant. The bypass pipe is connected to the riser pipe located upstream of the curved pipe.
Claims5
An air conditioner comprising:
- a compressor, a first heat exchanger, an expansion valve, and a second heat exchanger;
- a refrigerant pipe connected to the compressor, the first heat exchanger, the expansion valve, the second heat exchanger, and the compressor in this order, and configured to allow refrigerant to flow through the refrigerant pipe;
- a gas-liquid separator located at a portion of the refrigerant pipe, the portion connecting the expansion valve to the second heat exchanger, the gas-liquid separator being configured to separate the refrigerant flowing from the expansion valve toward the second heat exchanger into gas refrigerant and liquid refrigerant;
- and
- a bypass pipe connected to the gas-liquid separator and configured to direct the refrigerant separated in the gas-liquid separator to the compressor, wherein
- the compressor comprises
- a compressor body having a body suction inlet through which the refrigerant is suctioned in, and
- a suction muffler having a muffler suction inlet connected to the refrigerant pipe, the suction muffler being connected to the body suction inlet of the compressor body,
- the refrigerant pipe comprises a curved pipe configured to direct the refrigerant to the muffler suction inlet, the refrigerant being directed from a position lower than the muffler suction inlet to a position higher than the muffler suction inlet, and
- the bypass pipe is connected to a position of the refrigerant pipe, the position being located away from the muffler suction inlet by a distance that is at least ten times as long as an inner diameter of the curved pipe.
