Experimental Thermal Performance Comparison in the condenser of Heat Pump System using R22 and R134a Refrigerants

Heat pumps are among the most promising technologies to reduce global warming emissions and to more rationally use energy.The full exploitation of the potential of heat pumps is used more rationally for energy conversion with environmental-friendly refrigerants and higher Coefficient of Performance (COP).It requires further technological progress with modification in the condenser.Heat pumps often provide efficient solutions for heating the water.Although there is a gap in improving the efficiency of the heat pump, in many industrial applications much larger energy savings can be achieved by improving the design and by using different refrigerants.This investigation deals with the standardization of Heat pump and performance analysis of refrigerants for the heating of water in the condenser and to study the COP of Refrigerant, heat transfer rate and Log Mean Temperature Difference (LMTD).The study was performed in a heat pump that includes basic refrigeration elements and the counter flow heat exchanging method is used in the condenser to heat the water from the refrigerant.The analysis performed by using R22 and R134a are Refrigerants which are most used.The experimental results indicate that the efficiency of R134a is much better than R22.The performance of the designed heat pump was evaluated and the value of the Coefficient of Performance indicated that significant energy savings could be realized.
