Research On Optimized Design Of Solar Hot Water Storage Heating System

With the increasing of the scarcity of conventional energy resources and building energy consumption, renewable energy, especially solar energy applications in buildings is particularly important. Most of Chinese heating region is rich in solar resources, which makes solar heating systems very pomising.However, uneven distribution of solar energy resources hinders the development of solar heating systems,.Therefore, in order to take full advantage of solar radiation throughout the year to improve the system efficiency, the development of seasonal thermal storage heating system and the optimization of short-term thermal storage heating system is necessary.Combined with specific cases, we optimize the parameters that have important part in efficiency of the short-term thermal storage heating system to get the optimal design program in Yushu Qinghai.On seasonal heat storage solar heating system, combined with a case study, we make full calculation and analysis from the layout program of the collector, the ratio of the energy collected and stored and the thermal insulation of the pool for thermal storage to obtain the curve of the ratio of the energy collected and stored and the system control program for refernce.This paper also received the following conclusions:in the low latitude heating region, we can select the optimal angle of the collector through the calculation of the software to balance the differenceof the solar radiation in heating season and non-heating season.Considering the system load and hot water heating load,we can give priority to the use of short-term thermal storage heating system; in high latitude heating region, the huge difference in solar radiation in heating season and non-heating season makes the balance seems impossible.So we can give priority to seasonal heat storage system.The specific system solutions can be optimized through the solar heating system design and optimization software.
