Refrigerant Replacement and Atmosphere

Refrigerants such as ammonia is used for low-temperature systems. They include the power and cooling, ice rinks, and so on. Propane is used for special applications. Now, chlorinated hydrocarbons) were found to be harmful to earthР‚'s ozone layer, R-11 (CCl3F), R-12 (ccl2f2), and other similar compounds, which were in common use along with less harmful R-22 (CHClF2) had a lot of attention in the press. Recent international protocols (standards) set deadlines for the removal of harmful refrigerants from commercial use.

The change was, and is currently developed. The difficulty lies in the technical and part of the economy. First, find a liquid that has optimal performance and safe is a challenge. Secondly, to stimulate production for the manufacture and distribution of liquid at an affordable price and in sufficient quantities, is another. R-123 (CHCl2CF3) was designed as almost equivalent replacement for R-11, R-134a (CH2FCF3) replacement of R-12. R-123-still falls under criticism for what some of chlorine in it.

R-134a can be bought on the delivery of the auto-shops for automobile air conditioners. The majority of new cars should have R-134a in their air-conditioning systems.

R-22 is also widely used in residential and commercial air conditioning scroll compressor systems. He will also be terminated someday (probably in the period 20202030). However, finding a suitable, widespread replacement did not come so quickly, as first thought.
