Research of Solar Heating System Design Software
Abstract
Solar domestic hot water systems are very popular in China, and millions of square meters of collectors were sold every year. However, most of the collectors were used for making hot water, only a few collectors are used for space heating. By the implement of Chinese national standard “Technical code for solar heating system”[1], more and more solar heating systems will be built. At present, engineers in China are not so familiar with solar heating system, they need some convenient tools for design. According to the standard and research of solar heating systems, we developed a software for solar heating system design. This software will be of great use for extending solar heating utilization in China. Other commercially available software such as Trnsys, Polysun etc. was designed for simulating a given solar systems that the parameters were set up. They don’t have the function of economic analysis and haven ’t considered so much about Chinese national standards. Solar heating design software could be used for designing a new project and have the function of economic analysis, and was designed closely in accordance with Chinese relative national standard.
