摘要

碳氢制冷剂作为天然制冷剂的一种，因其热物理性质与环保性能（ODP为0，GWP极低）俱佳而受到国内外学者的广泛关注。本文从碳氢制冷剂的循环热力学性能出发，对碳氢制冷剂应用于小型商用冷柜的理论和实验进展进行论述，并介绍了压缩机、润滑油以及其他相关方面的研究进展。研究表明，相比于小型商用冷柜中使用的传统制冷剂，碳氢制冷剂的单位制冷量和性能系数较高，排气温度较低，实际运行时冷却速度和噪声水平都有较大改善。然而，碳氢类物质具有可燃性。虽然小型商用冷柜中碳氢制冷剂充注量较小，但要使得碳氢制冷剂在小型商用冷柜中大规模应用，需要做相应的泄漏燃爆实验。

Abstract

Hydrocarbons as one of the natural refrigerants have drawn much attention for their excellent thermophysical properties and environmental performance(ODP=0

GWP is extremely low). This paper compares the operational performances of HCs with several conventional refrigerants

discusses the research progress of the application of HCs on small commercial freezers from the point of theory and tests

and expounds the progress on compressor

lubricating oil and other relevant aspects. Compared to the traditional refrigerant used in small commercial freezers

hydrocarbons have much higher unit mass refrigerating capacity and COP

lower exhaust temperature. Moreover

in actual operation

their cooling rate is faster and noise level is lower. However

hydrocarbons are flammable. Although the refrigerant charge of small commercial freezers is small

relevant fire or explosion experiments should be done when hydrocarbons leak from a small commercial freezer.
