Exergy Analysis of a Vapour Compression Heat Pump Using Environmentally Friendly Refrigerants

Abstract

The paper presents the comparative exergetic analysis of heat pumps using refrigerants with different ozone depletion potential and global warming potentials. Globally, the air conditioning of houses is seen as a major energy challenge as the economic development of countries, the majority situated in hot climates, will lead to a growing demand for chilling. Added to this is the increasingly widespread use of heat pumps in areas with a temperate climate to increase energy efficiency. As a result, the environmental impact of refrigerants from ozone depletion potential and global warming potential point of view cannot be overlooked. On the other hand, an environmental benefit of high energy efficiency is the reduction of greenhouse gas emissions from fossil fuel combustion for various purposes. The purpose of this approach is to highlight how the use of different types of refrigerants will impact the exergy efficiency of heat pumps.
