To control the temperature of a heat medium supplied to a cold water load system while suppressing cost.SOLUTION: A refrigerator system 1 includes: a refrigerator 10; a buffer section (expansion tank 14) which has a first area A1 for storing a heat medium supplied from the refrigerator 10 to a cold water load system 12 and a second area A2 for storing a heat medium fed from the cold water load system 12 to the refrigerator 10; a cold water primary pump 18; a refrigerator inlet temperature sensor 26 which detects a refrigerator inlet temperature; a refrigerator outlet temperature sensor 28 which detects a refrigerator outlet temperature; a load inlet temperature sensor 30 which detects a load inlet temperature; a load outlet temperature sensor 32 which detects a load outlet temperature; and a control section 34 which controls flow rate of the heat medium passing the cold water primary pump so that a first temperature difference between the refrigerator inlet temperature and the refrigerator outlet temperature is equal to or less than a second temperature difference between the load inlet temperature and the load outlet temperature.SELECTED DRAWING: Figure 1 【課題】コストを抑えつつ冷水負荷設備に供給される熱媒体の温度を制御する。【解決手段】冷凍機システム１は、冷凍機１０と、冷凍機１０から冷水負荷設備１２に供給される熱媒体を貯留する第１エリアＡ１および冷水負荷設備１２から冷凍機１０に送られる熱媒体を貯留する第２エリアＡ２を有するバッファ部（膨張タンク１４）と、冷水１次ポンプ１８と、冷凍機入口温度を検出する冷凍機入口温度センサ２６と、冷凍機出口温度を検出する冷凍機出口温度センサ２８と、負荷入口温度を検出する負荷入口温度センサ３０と、負荷出口温度を検出する負荷出口温度センサ３２と、冷凍機入口温度と冷凍機出口温度との第１温度差が、負荷入口温度と負荷出口温度との第２温度差以下となるように冷水１次ポンプを通る熱媒体の流量を制御する制御部３４と、を備える。【選択図】図１
