Energy Analysis of Heat Pump with Subcooler

Original language description

The paper presents a model based analysis for ground source heat pump with use of a subcooler to increase efficiency of domestic hot water preparation. A new mathematical model for ground source heat pumps with subcooler has been built for the design ofsuch a heat pump and for the heat pump system simulations in TRNSYS environment. It has been shown that heat pumps with subcooler could theoretically increase the heating capacity by 10 to 25 % without the additional electric consumption. The simulationanalysis has been made to compare the reference heat pump with standard design and an identical heat pump but with a subcooler as additional heat exchanger in DHW system. The real annual energy savings of the DHW system with a heat pump with subcooler are 7.5%, the seasonal performance factor increases by 8.3 %.
