Simulation and analysis of water-loop heat pump’s application to large-scale commercial podiums

Dividing interior zone and perimeter zone in a large-scale commercial podium in Shijiazhuang city, simulating and analysing the heating and cooling loads of each of the zones in winter respectively, demonstrates the feasibility of water-loop heat pump’s application to such buildings of this region, and proposes the concept of energy-saving period, which provides a reference for the analysis of energy saving of water-loop heat pump and more accurate calculation of the energy saving amount.
