Abstract
The application of HVAC in the present age has affected our lives in much far-reaching range with an extensive variety of applications. HVAC is slowly becoming the pillar of our lifestyle and performs a crucial role in future sustainable growth. Vapour compression refrigeration system is predominantly used in an HVAC sector, which make use of the high-grade energy and causes depletion of ozone layer and global warming due to environmental unfriendly refrigerant. In this regard, ASHRAE has made available a list of low GWP refrigerant for various applications. This paper reviews thermodynamic, flammability properties of these low GWP refrigerants. The compatibility of the low GWP refrigerant with construction material and lubricant is presented.
