The condenser 31 is not necessarily limited to an L shape, and the L-shaped condenser 31 is only used for two condensation side air inlets 1201 to meet the requirement of increasing the heat exchange amount.

In particular embodiments, condenser 31 may be a multi-pass heat exchanger. For example, the heat exchanger can be a copper tube fin type heat exchanger, and can also be a micro-channel heat exchanger with flat tubes and collecting tubes. The use of the microchannel heat exchanger is advantageous in reducing the weight of the condenser 31 and reducing the size of the condenser 31.

At this time, since the tail portion 22 is closer to the condensation side air outlet 1203, the hot air flow can also take away a part of noise generated by the compressor 2, so that the noise of the whole machine can be reduced, and on the other hand, the tail portion 22 of the compressor 2 is far away from the vent hole of the condensation side air inlet 1201, so that the part of noise which is transmitted to the outside of the shell 1 through the vent hole of the condensation side air inlet 1201 when the compressor 2 operates can be weakened, and the combined action of the two aspects can obviously reduce the noise of the whole machine.
