Study of Applications of Solar Heating Systems with Seasonal Storage in China
MetadataShow full item record
In most northern parts of China, it is cold in winter and needs space heating in winter. This paper studies applications of solar heating systems with seasonal storage in China. A typical residential district was selected, and a solar heating system with seasonal storage was designed and simulated based on various conditions. The results indicate that 1) for many places of China, solar systems with seasonal storage can save conventional energy and can be competitive with gas-fired boiler heating; 2) when the ratio of volume of seasonal storage tank to collector areas is 3~5, the system performance is optimal for many places in China; 3) the obtained solar heat is mainly dependent on the solar irradiance, length of heating period and ambient temperature. Solar heating with seasonal storage in chilly places may also get good performance.
