Aquifer thermal energy storage (high-performance heat source well)

Legal regulations, environmental conservation, and technical challenges! By exchanging heat with a sense of the seasons, we can maintain the thermal balance of the ground.

I would like to introduce "Aquifer Thermal Energy Storage (High-Performance Heat Source Well)." As of March 2019, it accounts for approximately 28% of the ground heat utilization systems by the Ministry of the Environment. As a result of the operation on the secondary side, the heat recovery rate for seasonal use is 80%, and the SCOP when directly using cold water stored in winter during the intermediate period was 48.3. Furthermore, by balancing the amounts of cold water and hot water storage as well as the pumped water and circulating water, long-term use is possible in terms of both environmental protection and efficiency. 【Features】 ■ Construction of a pumping and circulating water switching type heat source well that is less prone to clogging ■ Suppression of underground subsidence risk ■ By reusing drainage with a pumping volume of 100m3 per hour, it is possible to secure a high COP for air conditioning in a building with a total floor area of 10,000m2. *For more details, please refer to the PDF document or feel free to contact us.
