Port valve and pipeline difference junction chamber exogenous wind cold heat exchanger and indoor air cooling heat exchanger, the outdoor air cooling heat exchanger pass through the member that throttles
Air cooling heat exchanger in part and pipeline junction chamber, it is unidirectional that the pipeline between the restricting element and indoor air cooling heat exchanger is equipped with first
Valve, the first check valve is from restricting element to indoor air cooling heat exchanger unilaterally connected；The outdoor unit further includes super-cooling pipeline, described
Air cooling heat exchanger in one end junction chamber of super-cooling pipeline, the other end are connected to restricting element and first unidirectional by the second check valve
On pipeline between valve, super-cooling pipeline further includes the heat release section for being disposed in the outdoor air cooling heat exchanger bottom, and the second check valve is by mistake
Cold pipeline is to restricting element unilaterally connected.
Further, the air refreshing device include full air cross adverse current plate heat exchanger, exhaust blower and be arranged on into
The air filter of air outlet.
Further, the restricting element is electric expansion valve or bidirectional flow heating power expansion valve.
Further, the outdoor air cooling heat exchanger and indoor air cooling heat exchanger are air fluorine heat exchanger.
Further, the compressor is totally-enclosed compressor.
Compared with prior art, the utility model has the advantage of：With refrigeration, heating and ventilation three kinds of operating modes,
The heat exchange of air inlet/outlet is carried out by full air cross adverse current plate heat exchanger in ventilation mode, it is significantly energy-saving；
During heating mode, super-cooling pipeline is to the outdoor further heat release in air cooling heat exchanger bottom again by entering after restricting element reducing pressure by regulating flow
Outdoor wind cold-hot machine, prevents outdoor unit from freezing, and ensure that its high efficient and reliable is run.
