空気調和機
Document Type and Number:
Japanese Patent JP6885857
Kind Code:
B2
Abstract:
To unify an amount of refrigerant flowing into an outdoor heat exchanger.SOLUTION: In an air conditioner in which an outdoor unit 1 including a compressor 4, a four-way valve 5 and an outdoor heat exchanger 6, and an indoor unit 2 including an indoor heat exchanger, are connected by a refrigerant pipe 3, the outdoor heat exchanger has a plurality of fins 12 for circulating the air, heat transfer pipes disposed in a plurality of rows in a direction to circulate the air and in a plurality of stages in a vertical direction intersecting with the air circulation direction, and connection pipes for connecting the heat transfer pipes to each other. A T-type branch pipe 16 is disposed on the connection pipe near a refrigerant inflow port to which a refrigerant flows, to divide the flow in the vertical direction in a case when the outdoor heat exchanger is used as an evaporator. A lower connection pipe 206 is disposed to connect a lower connection port of the T-type branch pipe and a connection port A1 of the heat transfer pipe at a position higher than the T-type branch pipe, and an upper connection pipe 207 is disposed to connect an upper connection port of the T-type branch pipe and a connection port A2 of the heat transfer pipe. A pipe diameter B1 of the upper connection pipe is larger than a pipe diameter B2 of the lower connection pipe to unify a refrigerant flow rate.SELECTED DRAWING: Figure 2
