Title: Method of operation of heat engine and heat engine proper
Inventor: SAVELEV ANATOLIJ A
IPC: F25B30/00
Filed: 1993-11-26
Granted: 1997-04-10
Abstract: FIELD: refrigerating engineering; manufacture of engines. SUBSTANCE: method of operation of heat engine consists in compression of working medium in compression chamber, forcing the working medium out compression chamber into expansion chamber, expansion of working medium in expansion chamber and forcing it out of expansion chamber to compression chamber. Forcing the working medium out of one chamber to the other is effected through at least one of heat exchangers having different temperature potentials; expansion process is conducted with expansion chamber disconnected from low-temperature potential heat exchanger. In course of operation of heat engine, degree of expansion is changed depending on change of relationship of temperature in heat exchangers and conditions of expansion and compression due to supply of additional working medium from low-temperature potential heat exchanger to expansion chamber. EFFECT: enhanced efficiency. 5 cl, 5 dwg
