近年来，喷射制冷系统的各种应用迅速增长。由于利用太阳能或废热来提供动力能源的可能性，它们可以被认为是空调技术中压缩装置的真实的替代品。在动力热源温度低于80 °C时，喷射式系统可以有效地与吸收式系统竞争。本文介绍了在一个专门建造的原型/台架上进行的实验研究，该原型/台架用于在低于75 °C的动力蒸汽温度下以异丁烷为工质的情况。本文分析了操作参数的影响。的喷射器的性能进行了介绍和讨论。给出了设计工况和非设计工况的典型压力分布。
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.
