The same control also activates a pump on the domestic water side that circulates water through the heat exchanger, where it is heated by the heat transfer fluid. 相同的控制也會啟動在室內水側的泵，使水穿過熱交換器，在熱交換器中，水被載熱流體加熱。
The transfer volumes from water to n-propanol-water mixtures and hydration numbers have been discussed in terms of the structural hydration interaction model. 結果表明，絲氨酸兩性離子部分和親水側鏈與正丙醇羥基間的相互作用對其遷移體積有正貢獻，且佔主導地位。
