Performance Evaluation of an Adsorption Heat Pump System Using MSC-30/R1234yf Pair with the Impact of Thermal Masses

In this study, we evaluated the performance of low Global Warming Potential (GWP) refrigerant R1234yf on activated carbon (MSC-30) for adsorption heating applications. The isotherms MSC-30/R1234yf were measured using a constant-volume–variable-pressure (CVVP) method from very relative pressure to practical operating ranges. data fitted with several isotherm models non-linear curve fitting. An improved equilibrium model was employed investigate influence dead thermal masses, i.e., heat exchanger assembly and non-adsorbing part adsorbent. isosteric where adsorbed phase volume accounted for. pump compared MSC-30/R134a pair literature. analysis covered desorption temperature ranging 60 °C 90 °C, evaporation at 5 condensation set 30 °C. It observed that MSC-30 relatively lower than those R134a by approximately 12%. coefficient (COP) selected found vary 0.03 0.35 depending source temperature. We demonstrated due latent heat, exhibits slightly cycle pair. However, widespread adaptation environmentally friendly in automobile systems may call implementation such as direct hybridization single refrigerant. presented work will be essential
