Zusammenfassung: | To provide an underground heat utilization system, a control device, a control method, and a program that can restrain fluctuations in a flow rate of water supplied to a heat exchanger.SOLUTION: An underground heat utilization system 10 comprises: a cushion tank 20 connected to a hot water well WLH and a cold water well WLC; a heat exchanger 30 connected to the cushion tank 20, and exchanging heat with a heat medium of a heat source machine R; a hot water pump 40; a cold water pump 50; a load pipe 60L; a load flowmeter 70L; and a control device 80. The control device 80 comprises a load flow rate acquisition unit for acquiring a load flow rate FL, a first determination unit for determining a first command C1 on the basis of the load flow rate FL, and a first command unit for sending the first command C1 to the hot water pump 40 or the cold water pump 50.SELECTED DRAWING: Figure 1
【課題】熱交換器へ供給される水の流量の変動を抑制できる地中熱利用システム、制御装置、制御方法、及びプログラムを提供する。【解決手段】地中熱利用システム10は、温水井戸WLHと冷水井戸WLCとに接続されているクッションタンク20と、クッションタンク20に接続され、熱源機Rの熱媒体と熱交換を行う熱交換器30と、温水ポンプ40と、冷水ポンプ50と、負荷配管60Lと、負荷流量計70Lと、制御装置80と、を備える。制御装置80は、負荷流量FLを取得する負荷流量取得部と、負荷流量FLに基づいて、第一指令C1を特定する第一特定部と、温水ポンプ40又は冷水ポンプ50に第一指令C1を送る第一指令部と、を備える。【選択図】図1 |
