FIELD: mechanical engineering.
SUBSTANCE: invention is related to pneumatic motors powered by compressed air/gas. The system of a combined air motor of a closed circuit with the supply of heat from natural sources includes air motor 1 combined with the first and second compressors 18 and 19, including a cylinder-piston group, a cylinder head with a system of intake and exhaust manifolds 2 and 3 with a valve mechanism, a piston block of compressors 18 and 19, driven by the nodes of air motor 1, including the inlet nodes and outlet nodes 4, 6 and 5, 7 of the working medium. Node 5 of compressor 18 along the first circuit 9 of the pipeline passes through heat exchanger 20, where the working medium is heated to the ambient temperature and heat exchanger 10, heated by third circuit 12 of natural heat source 13 and, further, is connected to collector 2 for transferring the working medium heated to the set temperature environment. Collector 3 is connected to inlet 6 of compressor 19 along second circuit 11 of the pipeline. From outlet node 7 of compressor 19, the pipeline passes through heat exchanger 8, where the working medium is cooled, through the throttle and evaporator 23 to inlet node 4 of compressor 18. Alignment of these flows of circuit 11 is carried out through heat exchanger 21 associated with them and pressure equalization unit 22.
EFFECT: invention is aimed at improving the efficiency of the pneumatic motor, increasing its efficiency and torque using renewable natural energy sources.
