In this study, performance characteristics of a water source heat pumps system using R452B as a alternative refrigerant are experimentally investigated. The performance of the heat pump adopting R452B was also compared with the system applying R410A. Heating capacities and COP of the R452B system are analyzed for system performance variables such as refrigerant charge, load temperature conditions. Results show that optimum amount of refrigerant charge at maximum point of COP curve. The heating capacity of R452B heat pump system showed a slightly lower values within 1% comparing with R410A system. The R452B system’s coefficient of performance was enhanced by 5% at heating mode.
