混合工质制冷是七十年代在美国发展起来的一种新的制冷技术。它采用新的热力循环,兼有蒸汽压缩制冷和空气制冷的主要优点。空气—水做工质的制冷机在美国已发展到接近商用阶段。本文简单介绍混合工质制冷技术的发展概况和基本热力学原理及基本流程;较为详细地论述流程参数的计算方法和主要附件—压缩—膨胀器的参数计算方法。
Mixed refrigerant refrigeration is a new refrigeration technology developed in the United States in the seventies. It incorporates a new thermodynamic cycle, combining the main advantages of vapor-compression refrigeration and air-cooling. Air-water refrigerant has been developed in the United States close to the commercial stage. This article briefly introduces the development of mixed refrigerant refrigeration technology and the basic principles of thermodynamics and basic processes; more detailed discussion of the process parameters of the calculation method and the main annex - Compressor - expander parameter calculation method.
