Loop structure recycles refrigerant.
Further, control valve is provided on the pipeline, the liquid of control pipeline is easy for using the advantageous effect of this step
Body circulates, and in reflux, closes, such liquid storage cylinder is with regard to that can form low pressure.
Further, the high-pressure air source is condenser exhaust gas high-pressure side air source.
The beneficial effects of the utility model：
The utility model is a kind of falling film evaporator, and turbulent flow is formed using spiral helicine heat exchanger tube, and heat exchange effect is improved with this
Rate；Return duct is additionally provided in the utility model, after can liquid being collected recycling, continues to form heat exchange with heat exchanger tube, with
This improves heat exchange efficiency；The utility model can using condenser exhaust gas high-pressure side air source as high-pressure air source, so as to form high pressure,
Refrigerant is pressed into inlet tube, the refrigerant that the utility model can will be unable to evaporating completely, circulated sprinkling evaporates, makes to change again
Heat pipe makes full use of.
