Summary

Improving the energy consumption efficiency in air conditioning (AC) systems has been increasingly necessary due to the sustainability vision of Kuwait 2035. The refrigerant vapor injection (VI) technique has been proven to significantly enhance heating cycles as well as cooling systems. The VI technique lowered compressor discharge temperature, improved cooling capacity, and therefore enhanced system’s coefficient of performance (COP). In this study, numerous data have been sampled from the literature and analyzed to correlate the VI technique’s cooling COP with operating conditions at hot climate. The data were sampled from previous experimental works at high ambient temperatures ranging from 20°C to 52°C. Three empirical formulas, each with unique correlations and temperature parameters, were developed to predict the COP of the VI cooling cycles with only a maximum mean absolute error of 3.81%. The results showed that the VI technique enhanced the cooling COP up to 34% during July (hottest month in Kuwait) when compared with the conventional cooling cycle. More experimental studies were recommended to thoroughly evaluate the cooling impact of the VI system when operating in the Gulf Cooperation Council (GCC) countries.
