Prolonged use of environment unfriendly refrigerants in high-grade energy systems has
resulted in increased greenhouse gas emissions and ozone layer depletion. This has …

A comprehensive review of two-phase flow characteristics, boiling heat transfer and
condensation outside and inside tubes of propane (R290) is presented in this paper. The …

R290 refrigerant offers good environmental protection and thermodynamic characteristics.
The feasibility of R290 replacing R134a was summarized through theoretical analysis and …

In this study, saturated flow boiling characteristics of R290/R1270 (65%/35% w) mixture and
pure R290 were investigated experimentally in a plate heat exchanger embedded with offset …

In this study, evaporation characteristics of mildly flammable R290+ CF3i mixture (35%+
65% by weight) were conducted experimentally in an offset strip fins (OSSF) embedded …

The flow boiling process of refrigerants indicates significant influence on the refrigeration
system performance. With the development of environmental standards in the last two …

The mechanism explanation for refrigerant and oil mixture heat transfer has puzzled the
researchers for many years. Disagreements on the mechanism of heat transfer in the …

Absorption technology becomes an attractive option for cooling or heating when driven by
solar thermal energy, residual heat from different processes, or geothermal energy. Further …

R32/PVE oil mixture has become a popular working pair of commercial refrigeration/heat
pump systems in recent years. This paper presented experimental study of oil retention and …

The aim of this study is to experimentally investigate the oil influences on transport, heat
