寒地向け地中熱利用システムの熱性能評価

抄録

Actual equipment incorporating newly developed design technology and elements was installed in the housing in Yamagata prefecture and operation started. SCOP averaged 3.5, 26% in terms of energy consumption efficiency. There is only economic consumption efficiency of 1.00 due to the difference in energy unit price, and there is almost no difference in running cost when considering it on a unit price basis. If it is the current energy unit price structure, unless the heat source side SCOP is 3.5 or more, there will be no operational cost difference. Discussion from an economic point of view is important not only from the viewpoint of energy, but also from the viewpoint of future.
