Abstract
This paper presents the results of an experimental investigation of a steam jet refrigerator suitable for renewable or low-medium grade waste energy applications. An experimental system of an ejector refrigeration system was constructed and fabricated. Different parameters of the ejector refrigeration system were investigated, such as the high-temperature evaporator (HTE) temperature, low temperature evaporator (LTE) temperature, and back pressure. The coefficient of performance (COP) of the ejector refrigeration system was determined. In addition, the effects of the operating temperatures on the COP and critical back pressure were investigated. The results are expected to motivate the use of ejector refrigeration systems for air-conditioning.
