Abstract：
Taking the freezing phenomenon of the air conditioning water coil in a northern nuclear power station as an example, according to the different principles of running water freezing and still water freezing，analyses and studies the freezing reasons of the air conditioning water coil. Proposes the measures to prevent the freezing of air conditioning cooling water coil and hot water coil, presents the advantages of the integrated upwind bypass heating coil in the aspect of antifreezing, and provides the methods for antifreezing design of HVAC equipment for nuclear power stations.
Keywords:air conditioning water coil, freezing, integrated upwind bypass heating coil, antifreezing nuclear power station
