Ecological and energy efficiency analysis of ejector and vapor compression air conditioners

A methodology of eco-energy analysis of power-intensive equipment, based on the calculation of the life cycle greenhouse gas emissions, is presented. According to the presented methodology, a comparative eco-energy analysis of vapor compression and ejector air conditioners operating with R245fa and natural refrigerant R600a at different working conditions in China and Ukraine has been undertaken. As a result, new eco-energy indicators, which allow for the determination of the prospects of alternative air conditioning system implementation, have been developed. It is shown that ejector air conditioners have eco-energy prospects for implementation if they are driven by waste heat from several industries.
