Analysis on energy-saving effect and environmental benefit of a novel hybrid-power gas engine heat pump

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.

Boiled Water

Under the situation of energy crisis, air source heat pumps are paid more attention recently. In terms of energy saving, the feasibility and performance of boiled water machine with air source heat pump are studied by experiment in this paper. The results are as follows: the best outlet temperature of heat pump is 55°C in winter, and that is 65°C in other seasons correspondingly. Electromagnetic heater is used as the accessorial heating method, which can heat water to 95°C so as to be fit to drinking. Moreover, the energy saving effect of the unit is remarkable. At the end of the paper, the preliminary conception of structure and automatic control is proposed.
