摘要
本文介绍了一种利用螺杆压缩机二次吸气制取两种蒸发温度冷量的系统,该系统与传统系统比较一般可增加30%~70%的冷量,且制冷系数COP提高25%~45%。文章通过理论分析,公式计算,数据验证,以及典型举例,认为该系统是一种有推广意义的节资、节能系统,对有关工程设计和理论研究人员有一定参考价值。
The article introduces a refrigeration system, which can su-pply two evaporating temperature by making use of the screw compressortwice suction characteristic, it can normal increase capacity by (30~70)%and efficiency by (25~45)% as compared with traditional system. This article considers that it is a cost saving and energy saving systemwith the spreading significance by means of the theoretical analysis, thedetum test and verification, and the typical example. the article has certainreference for the relative people of project design and theoretical research.
