摘要
In our study, an operation regulation scheme and a control strategy of Solar Heating System with Seasonal Water Pool Heat Storage (SHS-SWPHS) was presented. Our methodology aimed to match the heating source with the heating load. Compared with the conventional heat system, the water temperature of heat storage will continuously decrease during the heating period. Our study firstly proposed the indirect heating, direct heating and water source heat pump auxiliary heating modes depending on different temperature levels. These modes correspond to the requirement of the low-temperature limit of radiant floor heating. According to the regulation principle of central heating, the regulatory scheme and operation control strategy under different heating operating conditions are investigated in order to accomplish the automatic control of SHS-SWPHS. The regulation analysis and regulation parameters were optimized by applying in our application cases.
