15. Design and Analysis on a Kind of Compound Renewable Energy System for Heating

This paper aims to optimizing the conjunctive use of sewage source heat pump technology and solar hot water heating technology and improving the drawbacks when they are, respectively, applied. By adopting key technologies such as cooperation technology of sewage source heat pump technology and solar hot water heating technology, efficient phase change technology, scientific operation strategies, continuous automatic control of each equipment and others, the system realizes the efficient operation of sewage source heat pump units and solar hot water heating system, storage and delay of energy, full utilization of peak and valley time price policy which enables the system to gain the best heating effect and efficient operation of each equipment. We conduct a test and statistical analysis on the indoor comfort parameter, electricity, and water consumption of major equipments and the performance change of equipments at operation time for the system, and continuously optimize design conception for providing significant reference and guidance to the future field of renewable energy, finally completing the transition from nonrenewable energy to renewable energy.
