Abstract

In recent years, energy issues related to the use of fossil and renewable energy, as well as their impact on the environment such as climate change, ozone layer depletion and global warming has received significant attention. Maintaining energy availability within the safe limits and reducing the energy usage to combat environmental problems is is important for a sustainable future. The use of environmentally friendly refrigeration technology is one of the ways to solve the energy and environmental issues. In this study, a heat pump system is proposed. This system was modelled using MATLAB 2017a and REFPROP version 10 software. The refrigerant used in this study is an environmentally friendly refrigerant R1224yd. The analyses of exergy, exergoeconomic and the exergoenvironmental impact are conducted in this study. The results showed that the rate of exergy destruction significantly affects the performance of the system, as well as the exergoeconomic and exergoenvironmental value. In this study, the compressor had the highest exergy destruction rate, which about 343.51 W or 39.39% of the total exergy destruction followed by condenser 307.60 W, evaporator 143.37 W, and expansio valve 77.51 W. Therefore, the compressor can be used in the future for improving the system efficiency, as well as for assessing the economic and environmental impact.
