3 FAQs about [China s high-efficiency solar energy engineering thermal equipment]
Can solar energy stabilize space heating?
The simulation results show that the system can stabilize space heating. By storing solar energy into the soil in the transitional season, the imbalance efficiency can be kept at 1% to decrease the phenomenon of cold accumulation in the soil and ensure the COP stability of the heat pump unit.
Why is heat storage important in solar systems?
Heat storage is important in solar systems to compensate for time differences between the availability of the heat source and the availability of the heating demand. A stratified fluid storage tank was considered in the current study.
Can solar thermal energy storage reduce GHE length?
The study demonstrated that the hybrid GSHP system incorporating solar thermal collectors was feasible for the space conditioning for heating-dominated houses. Rad et al. reported that solar thermal energy storage in the ground could significantly reduce the necessary GHE length [ 16 ].
