Ｒ１３４ａ是汽车空调zui理想的替代工质，但Ｒ１３４ａ与原汽车空调系统不相容，必须对系统各部件作一些改进。该文论述了Ｒ１３４ａ汽车空调系统各部件的改进措施。

对大气臭氧层有破坏性物质的替代计划,阐述了用R134a制冷剂替代R12制冷剂的可能性。

R12的替代制冷剂 R134a 由于潜热小,不溶于矿物油以及分子体积小等,使得替代过程复杂,耗资巨大,还要相应调节制冷系统改造生产线。全球变暖形势严峻,因此,开发价格低廉、替代工艺简单更环保的制冷剂过渡替代物非常迫切。

R134a is the ideal substitute working fluid for automobile air-conditioning, but R134a is incompatible with the original automobile air-conditioning system, and some improvements must be made to each part of the system. This paper discusses the improvement measures of each component of R134a automobile air conditioning system.

The replacement plan for the ozone-depleting substances in the atmosphere expounds the possibility of substituting R134a refrigerant for R12 refrigerant.

The replacement refrigerant of R12, R134a, due to its small latent heat, insoluble in mineral oil and small molecular size, makes the replacement process complicated and expensive, and the production line of the refrigeration system needs to be adjusted accordingly. The situation of global warming is severe, therefore, it is very urgent to develop transitional substitutes for refrigerants with low price, simple and environmentally friendly replacement processes.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a rapid and high-efficiency gas chromatography qualitative and quantitative analysis method for automotive air-conditioning refrigerant R134a. The HH-R134A chromatographic column was used for detection with thermal conductivity cell detector, and the quantification was performed with area normalization method. The results show that the method is simple to operate, has strong practicability and good repeatability, and can be used for rapid analysis of R134a, a refrigerant in automobile air-conditioning.
