Problems solved by technology

[0005] However, in the air conditioner described in Patent Document 1, the outdoor heat exchanger that functions as a condenser during cooling operation has a slow flow rate under cooling conditions with a low evaporation temperature. When the refrigerant pipe flows out, the distribution of refrigerant is prone to deviation
Furthermore, when the distribution of the refrigerant is uneven in the outdoor heat exchanger, there is a problem that the performance as a condenser cannot be fully exhibited.

Embodiment approach 1

[0019] figure 1 It is a refrigerant circuit diagram of the refrigeration device according to Embodiment 1 of the present invention.

[0020] like figure 1 As shown, the refrigerating apparatus according to Embodiment 1 includes an outdoor unit 100 and an indoor unit 200, and the outdoor unit 100 and the indoor unit 200 are connected by piping. In addition, the refrigeration device includes a refrigerant circuit through which a refrigerant circulates, and the refrigerant circuit is formed by sequentially connecting a compressor 1 , a condenser 3 , an expansion device 6 , and an evaporator 7 through piping.

[0021] The outdoor unit 100 includes a compressor 1 and a condenser 3 . The compressor 1 is constituted by, for example, a capacity-controllable inverter compressor or the like, sucks in a low-temperature and low-pressure gas refrigerant, compresses the gas refrigerant, turns it into a high-temperature and high-pressure gas refrigerant, and discharges it.

[0050] Hereinafter, Embodiment 2 of the present invention will be described, but the description of parts overlapping with Embodiment 1 will be omitted, and the same parts as Embodiment 1 or corresponding parts will be given the same reference numerals.

[0051] Figure 5 It is a refrigerant circuit diagram of the refrigeration apparatus according to Embodiment 2 of the present invention.

[0052] like Figure 5 As shown, the condenser 30 according to Embodiment 2 includes a first bypass pipe 331 branched from the first inflow portion 311 and connected to the second inflow portion 321 . In addition, the condenser 30 includes a second bypass pipe 332 branched from the second inflow portion 321 and connected to the second outflow portion 322 . In addition, the condenser 30 includes a flow path switching device including, for example, a first valve 51 , a second valve 52 , a third valve 53 , a fourth valve 54 , and a fifth valve 55 that are electromagnetic on-off valves.

Abstract

The condenser includes: a first condenser for exchanging heat with the refrigerant compressed by the compressor; and a second condenser for exchanging heat with the refrigerant after heat exchange in the first condenser. The refrigerant performs heat exchange, and the first condenser has: a first inflow part, which allows the refrigerant compressed by the compressor to flow in; The refrigerant after heat exchange in the first condenser flows out.

Description

technical field [0001] The present invention relates to a condenser used in a refrigerant circuit, and a refrigeration device including the condenser. Background technique [0002] Conventionally, there is an air conditioner using a parallel-flow condenser as an outdoor heat exchanger. The parallel-flow condenser includes a plurality of refrigerant tubes, two headers connected to the ends of the refrigerant tubes, and A plurality of fins between adjacent refrigerant tubes (for example, refer to Patent Document 1). [0003] In the outdoor heat exchanger described in Patent Document 1, a connection pipe is attached to one header, and the fluid flowing out from the first end of the connection pipe flows into the refrigerant after hitting the inner surface of the header. inside of the tube. Therefore, in this outdoor heat exchanger, the fluid flowing out from the first end of the connecting pipe does not flow into only a part of the refrigerant pipes in a concentrated manner, ...
