Title:
REFRIGERANT CIRCUIT AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/002086
Kind Code:
A1
Abstract:
In the present invention, the following are provided: a plurality of gas-liquid separation devices (1) for separating a gas-liquid two phase refrigerant (51) into refrigerant vapor (52) and refrigerant liquid (53); a flow-path switching valve (11) that is connected to the upstream side of the gas-liquid separation devices (1) and that opens and closes so as to switch the flow path of the gas-liquid two phase refrigerant (51); an evaporation heat exchanger (3) into which flows the refrigerant liquid (53) separated out at the gas-liquid separation devices (1) or the gas-liquid two phase refrigerant (51); a header (2) provided on the upstream side of the evaporation heat exchanger (3) and perpendicular or inclined with respect to the evaporation heat exchanger (3); a compressor (7) provided on the downstream side of the evaporation heat exchanger (3); and a plurality of by-pass channels (6) that are connected to each of the gas-liquid separation devices (1) and through which the refrigerant vapor (52) passes. Refrigerant vapor (52) which has passed through the plurality of by-pass channels (6) and refrigerant vapor (52) which has passed through the evaporation heat exchanger (3) converge at a first convergence point (α) between the evaporation heat exchanger (3) and the compressor (7).
