In this case, tightly fitting dampers are required to prevent reverse thermosiphoning at night, which could freeze water in the heat exchanger coil.

在这种情况下，需要紧密配合的阀来阻止夜间反向虹吸，以防止水在热交换器盘管中被冷冻。

Then, the dynamic heat exchange of a coil heat exchanger was simulated and some conclusions were drawn in terms of its regular laws of heat exchange.

以此为基础，对风机盘管换热器的换热进行了动态仿真模拟，得到了风机盘管换热器换热量随各进口参数扰动而发生变化的一般性规律。
