In main frame；
(3) air enters moisture separator and separates air and moisture, and moisture is discharged, and air is filtered into the oil removing of AA levels
Device carries out filtration oil removing；Then air is divided into two-way, all the way into cooling driers, all the way into dryer；
(4) air carries out heat exchange cooling, air in freezing heat exchanger through freezing heat exchanger in cooling driers with refrigerant
Go out to converge with the air that cooling is dried through dryer after cooling driers and flow to AR level dust filter units, the sky after dust-filtering
Gas enters AAR levels dust accurate filter secondary filter and discharges.
Preferably, it is integrated in step (1) when air reaches certain pressure in integrated-type screw host in technical scheme
The pressure valve of type screw host gas outlet is opened, and air flows to moisture separator by air pipe, the pressure sensing on air pipe
Device detects air pressure value.
Preferably, in technical scheme, Jing freezing pipelines flow into refrigerant after the refrigerant heat exchange in step (4) in freezing heat exchanger
Cooler, opens blower fan and is cooled down, and the refrigerant after cooling compresses Jing after the filtration of refrigerant filter into cold medium compressor, then
It is back in freezing heat exchanger.
Compared with prior art, the present invention has the advantages that：
Oil in air inlet is cooled down by oil cooling unit structure and is recycled, separate the moisture in air inlet by cooling driers, together
When cool down air inlet, it is adaptable to aviation field, reduce the corrosion of oil, moisture to machine, extend service life.
