Abstract This paper analyzes the energy saving effect and optimal operation of the integrated park type energy system. The park type integrated energy system includes photovoltaic power generation system, ground source heat pump system, solar air conditioning system, regenerative electric boiler system and solar hot water system and so on. The energy saving benefit calculation model of each subsystem is established, and according to the operation history data of each subsystem, the calculation results of each subsystem are analyzed. It shows that: The energy saving income of photovoltaic power generation system is 734,200 yuan/year. The main revenue comes from the second and third quarters, during which it should pay attention to the maintenance of photovoltaic modules to ensure the maximum energy saving benefit. The energy saving income of ground source heat pump system in summer is 155,900 yuan/year, and the energy saving effect is not significant. It can cooperate with traditional units for cooling in summer. The heating in winter in the park is provided by ground source heat pump system, regenerative electric boiler system and solar energy air conditioning system. Its energy saving benefit is 3.995 million yuan/year which is the main source of energy saving income in the park, with remarkable energy saving effect.

According to China's current energy present situation, the use of renewable energy, saving energy and reducing consumption has become the energy industry development should follow the basic principles. Electric boiler-ground source heat pump system as one kind of building energy saving technology, mainly in soil source heat pump renewable energy utilization. In this paper the boilers and soil source heat pump matching design and operation model research, from energy efficiency, economic and technical analysis, environmental benefit analysis into consideration, and concludes that the electric boiler-ground source heat pump system has the obvious energy saving and environmental benefits.

Based on the heating season testing of ground-source heat pump system (GSHP) in Wuhan, the article discussed the energy efficiency ratio of ground-source heat pump system under the heating conditions. By comparison with conventional chillers & coal-fired boiler system, the system energy savings, environmental benefits and incremental payback period are analysized. There comes to the conclusion that the energy saving rate of the heating season is about 19.74% higher than that of the cooling season, reducing 18.35 kg carbon dioxide emissions, 0.15kg of sulfur dioxide and 0.0743 kg of dust per unit construction area each year. Also this article concludes the annual energy saving rate of ground-source heat pump system equals to that of water-source heat pump, with the payback period 22% longer and the cost-effective ratio 32% higher.
