Abstract: According to the features of energy utilization in campus buildings, a hybrid system based on heat sink form with solar energy and ground source heat pump is introduced in this paper. By theoretical calculation and experimental validation for heat transfer effect of the heat sink and economic analysis of fuel cost, it was confirmed that the system could efficiently match solar energy with ground heat. Renewable energy storage was realized and operation cost was saved.

Abstract: According to the phenomenon of insufficient utilization of the geothermal water in the heat supply system of a campus in Tianjin, an optimization retrofit scheme with cascade utilization of the geothermal water is introduced in this paper. The energy efficiency of the heat supply system was improved after the retrofit: 30% of the electricity consumption was saved and an extra building area of 120,000 m2 could also be served by the same heat supply system.
