in this research, the performance of heat pump using refrigerant to water is experimentally investigated. The
experiments were performed for the range of 30°C to 35°C atmospheric temperature. The heat pump, using R-134a was
set for the various load, maintained by evaporator water flow rate. The performance of heat pump was carried out by
varying the parameters like condenser water temperature and mass flow rate, evaporator water temperature and mass
flow rate. The heating coefficients of performance were calculated based on experimental values. From the experimental
results found that by change in mass flow rate of evaporator water the temperature at evaporator side is increases and
increment in atmospheric temperature the, C.O.P of the system lies to range1.4 to 1.9. It is seen that C.O.P of heat pump
is mainly depends upon parameters such as mass flow rate and temperature. Temperature of condenser water outlet is
achieved up to 45°C
