Air-Cooling Open Cycle with Peripheral Machines

Air-conditioning plants With air as working fluid In open cycle have been wtdely employed and they provtde high performances In terms of compactness and low weight. In the on-aboard systems Interesting developments have been obtained as well as In the land applications same good improvements can be expected. As a matter of fact the absolute lack of pollution problems and the compactne:ss can make this kind of plant suitable ·for all that applications in which reliabtltty, maintenance and easy service are fundamental qualifications. The paper analyses the possibWty to employ the peripheral machines as compressor and turboexpander In order to improve the compactness and to reduce costs. A complete theoretical analysts of the thermodynamtc cycle ls followed by the schell;latlc description of a small aircoollng experimental prototype.
