Abstract

Abstract: Space heating accounts for large percentage of building energy consumption, which may cause air quality deterioration in cold climate area. Solar energy systems and ground-source heat pumps are two promising means of reducing the consumption of fossil energy and the emission of green-house gas. Taking a typical office building at Tianjin as an example, the application of solar heating system assisted by ground-source heat pumps was studied. The entire system was modelled via the TRNSYS simulation environment and the energy performance was evaluated based on the winter time operation schedule. It shows that the overall system COP can reach 8.17 and the heat pump COP is increased.
