Research on Solar Heating Technology for Rural Single-Family Homes in Severe Cold and Cold Zones of China
Abstract
China's solar energy resource is very abundant because of its vast area.The fact that the amount of solar energy growths with increasing latitude is just perfect suit for the heating demand of China. Currently, the technology of solar heating mainly focus on three issues: firstly, solar heat supplementary questions, secondly, safety issues of solar products, thirdly, solar system optimization problems. Take into consideration of general solar heating systems used in China, and follow the principle of priority use of the environmental heat resource, a solar thermal storage heating system and a solar air source heat pump combined heating system were established respectively under the TRNSYS platform. In the viewpoint of room temperature guarantee, the heat pump system performed better than the energy storage system. But the former expended much more electricity than the later. Finally, taking the comprehensive performance coefficient (SCOP) into consideration, the thermal storage system suits better for practical use in rural zones of China.
