AMMONIA ATMOSPHERIC-HEAT ENGINE AND ITS OPERATING PROCESS

摘要

FIELD: power engineering. SUBSTANCE: engine has heat pump and ammonia turbine whose inlet pipe communicates with condenser and outlet pipe, with hot agent heat exchanger of heat pump; it also has ammonia boiling heat exchanger and electric current generator mounted on common shaft with heat pump and ammonia turbine. Heat pump runs at maximum permissible efficiency and under conditions when air compression efficiency within condenser ηc = 0.85, air expansion efficiency inside air turbine ηp = 0.95, air temperature at air turbine outlet = 335 K, and l = 1.35. EFFECT: improved efficiency of recovering not only low-quality heat of thermal water sources, waste process heat, but also solar heat dissipated throughout atmosphere. 2 cl, 2 dwgu
