Abstract

In this 21st century, scientific enterprise has a driving force known as safety value and care value for environment; researchers are striving to fulfill these values. Policies like the Montreal Protocol and the EU Directives incentivize this research. The feasibility of R1234yf is introduced in car air conditioner application. This is an experimental study on car air conditioning system with drop in substitute R1234yf for R134a. For the experimental study, a test rig was developed, in which actual car conditions were simulated. Performance parameters like work input to the compressor, coefficient of performance, refrigerating capacity and overall heat transfer coefficient were taken into consideration.


Description

The world is now serious about climate change and has taken serious steps to protect the environment. Mobile air conditioning has a great share in Hydrofluorocarbons (HFC) market sales and obviously in pollution due to greenhouse gases. The impact of refrigeration and air-conditioning installations on climate change has been principally through energy consumption and the past emissions of chlorofluorocarbons (CFCs). Natural refrigerants having potential for substitute to synthetic refrigerants have been presented here. Substituting CFCs with low leakage HFC systems that have improved efficiency will mean a net reduction in the effect on the global climate; still, they contribute to global warming, which is a serious concern.
