Abstract

In order to evaluate the performance of a solar-groundwater heat pump (SGHP) unit associated with radiant floor heating, a experimental installation was designed and established, the performance was measured and compared with the conventional central heating system(CCHS). The results shown that the new system has an energy-saving rate of 30.55% compared with the CCHS. The floor heating systems can save energy 18.96% compared with the traditional radiator. In the present experiment, the solar energy contribution rate was about 24%. Taking the basic energy (primary energy) consumption as a benchmark, the SGHP can reduce energy consumption by 30.55% compared with the traditional regional boiler room heating system. As the solar fraction increases from 0% to 100%, the COP of heat pump units and overall system are increased 6.44% and 19.34%, respectively
