heal.abstract	This paper discusses the behavior of ammonia (R-717) through an ejector, operating in an air-conditioning system with a low temperature thermal source. For the detailed calculation of the proposed system a method has been developed, which employs analytical functions describing the thermodynamic properties of the ammonia. The proposed cycle has been compared with the Carnot cycle working at the same temperature levels. The influence of three major parameters: generator, condenser and evaporator temperature, on ejector efficiency and coefficient of performance is discussed. Also the maximum value of COP was estimated by correlation of the three temperatures for constant superheated temperature (100 degrees C). The design conditions were generator temperature (76.11-79.57 degrees C), condenser temperature (34-42 degrees C) and evaporator temperature (4-12 degrees C). (C) 1999 Elsevier Science Ltd.
