According to Internal Energy Agency (2012), the world energy demand will increase by 35 percent from 2010 to 2035, by taking care of three E'S (EARTH, ENVOIRNMENT and ECO FRIENDLY). This increase is associated with world population and pollution, economic and global growth especially in developing countries. The consumption of HVAC amounting up to 40% of the total electricity consumption. That is why it is very important to develop highly efficient HVAC products. Combination of Energy, Efficient and Eco Friendly HVAC product is key focus for HVAC industry, many highly energy efficient as well as ecofriendly products are developed, and still huge advancement are required. There are several ways to improve the performance of HVAC products either household or industrial, sometimes advancements and improvements requires high capital cost in order to maintain sustainability. One of the finest, simple and economic way to maintain all these aspects is the use of Ejector as an expansion device by replacing expansion or throttling valves. Complete cycle named as EJECTOR EXPANSION REFRIGERATION SYSTEM WITH LIQUID VAPOUR HEAT EXCHANGER inside the mixing chamber of Ejector (EERS), by using one Eco Friendly refrigerant Propylene (R1270). This paper provides the description of the geometric parameters of ejector cycle using R-1270 as a refrigerant.
