自水-空气单元式热泵问世以来，冷凝器水温的控制几乎没有发生任何变化。本文展示了优化冷凝器水温以使全年COP值最大化的重要性，并讨论了通过使用可用硬件实现这一点的方法。尽管任何水冷式制冷系统都可以从冷凝器水温优化中受益，但对于水-空气单元式热泵等全年运行的系统来说，它具有特殊的价值，其中一些机组处于冷却模式，而另一些机组处于加热模式。引用: 研讨会，阿什雷交易，第86卷，第2部分，科罗拉多州丹佛

The control of condenser water temperature has undergone virtually no change since the advent of the water-to-air unitary heat pump. This paper shows the importance of optimizing condenser water temperature to maximize COP values throughout the year and discusses methods for accomplishing this through the use of available hardware. Though any water-cooled refrigeration system can benefit from condenser water temperature optimization, it is of particular value to systems such as the water-to-air unitary heat pump which operate year-round with some units in the cooling mode while others are in the heating mode.
