Performance and Analysis on Winter Air Conditioning Testing with Limited Pressure

Mechanical Engineering

This project is related to the future phase-out of hydro chloro fluoro carbons (HCFCs) used in air conditioning system. Most commonly used refrigerant is R22. In field of refrigeration everyone trying to find alternative refrigerants for R-22. Because hydro chlorofluorocarbons (HCFCs) including R-22 is promised to be banned as per the Montreal protocol. Several refrigerants like R290, R407C, R410A, R134a are emerged as substitutes to replace R-22, the most widely used Fluoro carbon refrigerant in the world. It is become necessary to replace the R-22 by other refrigerants which are environmental friendly. In this project R-290 (hydrocarbon) is selected as alternative for R- 22. Because it has zero Ozone Depletion Potential and almost zero Global Warming Potential. The product is typically at least 97.5% pure with minimal level of critical impurities including moisture and unsaturated hydrocarbons. This make it ideal for use in all type of refrigeration systems.
