Abstract

Winter heating methods in rural regions of Northern Jiangsu, China are relatively outdated, and measures are needed to take promptly. This research used DeST to get the heat load of a 190 m² building, and dynamic meteorological and building structural parameters were taken into the calculation. This research designed a physical model of Solar Assisted Ground Source Heat Pump (SAGSHP) and used an instantaneous energy system simulation software (TRNSYS), to simulate the dynamic performance of the system. It was found that solar heating was unstable, and solar heating system only started when the intensity of solar radiation reached a certain value. Solar system was mainly affected by the intensity of solar radiation. The addition of the solar system allowed the SAGSHP system to maintain a high energy efficiency, and the number of days with an energy efficiency of more than four was close to 61%.
