Air Cycle Refrigeration Aircraft Ground Environmental Control Systems

The airplane ground environmental control system is the important task of ShenYang Hang Da airplane loading equipment company. It is investigated for the demand of new aeronautic equip.The paper investigates airplane ground environmental control system of air circulating refrigeration , according to airplane technique requirements. A new project of technique system is advanced. Analysis and account and design, are performed. And a sample machine is produced. In the experiment investigation, performance testing is finished. The system is optimized again for improving its rate of energy consuming and effect. The result of investigation indicates that the project is logical, the accounting method is right and credibility, and the testing data is satisfied. Compare with the alike productions in our country, this system keeps ahead on technique and its cost is low. It is credibility, maintain easy, and no surroundings pollution. It is worth extending for products best.With the result of this investigation, the lacking pressure problem and removing water problem of the ground environmental control system have been solved and it has been filled in the gaps in the domestic research in this field.
