Basic Research of Solar Seasonal Thermal Storage Capacity Increase to Existing Heating System

Based on the principle of deepening the use of solar which is renewable energy, we proposed a new system that utilize solar seasonal thermal storage capacity to increase existing district heating, the peak load will be met by solar seasonal thermal storage is the salient feature of this system. This article described related content of the system basic research, including system design and operation control mode, also discussed the physical model of the major part of the composition system, to lay the foundation for in-depth study.
