摘要：

The rapid growth of various applications of the ejection refrigeration systems could be observed recently. Because of possibility of the application of solar or waste energy to supply the motive energy they can be thought as a real alternative to compression devices in air-Conditioning technologies. Ejection system can effectively compete with absorption system under temperature of the motive heat source lower than 80 C. The paper deals with experimental investigations carried out on a specially constructed prototype/stand for the case of isobutane as a working fluid under motive vapour temperature below 75 C. The effects of operation parameters are analysed in the paper. The performance of the ejector is presented and discussed. Exemplary pressure distributions for on-design and off-design conditions are presented. (C) 2013 Elsevier Ltd and IIR. All rights reserved.
