Abstract

Due to the concerns of global warming, many countries are strictly tightening regulations about greenhouse materials. In case of refrigeration systems, there are many ongoing researches on low global warming potential (GWP) refrigerants. GWP refers to a measure of how much the given substance can give effect on the global warming. Relative GWP scale of certain substance is measured comparing to the GWP of Carbon Dioxide, 1. In this review, condensation heat transfer and pressure drop of various low GWP refrigerants like R-1234ze, R-1234yf, R-1233zd and so on are investigated. Theses refrigerants all have GWP measure of under 100. Due to the differences on condensation heat transfer and pressure drop for refrigerants in various heat exchangers, investigation is also carried out for other types of heat exchangers like plate type, shell and tube type etc. Based on the investigations, experimental correlations of condensation heat transfer and pressure drop are compared.
