AIR HEATING AND COOLING DEVICE

摘要

FIELD: heat-power engineering. SUBSTANCE: device has drive and compressor with expander made from diaphragm bellows with folding corrugations. Compressor bellows are located in common hot cavity of housing. Bellows of compressor and expander are located coaxially. EFFECT: enhanced efficiency; reduction of spurious spaces and hydrodynamic losses due to facilitated heat exchange between working medium and air without use of external heat exchangers and devices for pumping air through them. 2 cl, 1 dwgc
