ABSTRACT

Most domestic refrigeration used in Nigeria contains significant quantities of ozone layer depleting CFCs such as RI1 and R12. This has led to the increasing evaporation temperature and low refrigeration cycle coefficient of performance. This paper takes a look on how performance of house use refrigerators can be enhanced using new compound of C₂HF₂CL₂ and C₂H₂F₄.
