制冷是一种将物体的热量转移到冷却和冷冻的过程，以保持环境温度，从而达到保存目的和舒适性。制冷剂是用于空调和制冷系统的材料。本文介绍了第一、第二、第三和第四代制冷剂的发展和历史。此外，重点是第四代制冷剂，即HFO-1234 yf，其具有零臭氧消耗潜势和非常低的全球变暖潜势。介绍了HFO-1234 yf的合成工艺、化学性质、应用及消费标准。
Refrigeration is a process to transfer heat from the objects for cooling and freezing for maintaining the temperature of surroundings for preservation purposes and comfort. Refrigerants are the materials to use in air-conditioning and refrigeration system. This article describes the developments and history of the first-, second-, thirdand fourth-generation refrigerants. Moreover, the focus is on a fourth-generation refrigerant, viz. HFO-1234yf having zero ozone depletion potential and very low global warming potential. Synthesis procedure, chemistry, applications and consumption norms of HFO-1234yf are explained.
