地中熱利用熱回収ヒートポンプシステムおよび地中熱利用熱回収ヒートポンプシステムの運転方法
Document Type and Number:
Japanese Patent JP7081761
Kind Code:
B2
Abstract:
To efficiently operate an underground heat exchanger while securing heat collecting and radiating amount in an underground heat pump.SOLUTION: A piping system 13 includes: a first pipe 21; a plurality of second pipes 22 which supply a heat medium passed through the first pipe 21 to each of a plurality of heat pumps 12; a plurality of third pipes 23 to which the heat medium passed through each of the plurality of heat pumps 12 is supplied; a plurality of fourth pipes 24 and a plurality of fifth pipes 25 to which the heat medium passed through each of the plurality of third pipes 23 is supplied; a sixth pipe 26 which joins the heat medium passed through each of the plurality of fourth pipes 24 and supplies the heat medium to the first pipe 21; a seventh pipe 27 which joins the heat medium passed through each of the plurality of fifth pipes 25 and supplies the heat medium to an underground heat exchanger 11; and an eighth pipe 28 which supplies the heat medium passed through the underground heat exchanger 11 to the first pipe 21. A flow rate adjusting section 17 adjusts a flow rate of the heat medium from the third pipe 23 to the fourth pipe 24 and the fifth pipe 25.SELECTED DRAWING: Figure 2
