Reduce the fan speed according to the decreasing exhaust temperature. If the temperature is too low, ensure that the decrease in condensate temperature in each section is not too large, generally not lower than 10°C below the saturation temperature at the corresponding pressure. If the temperature is too low, reduce the fan speed to a very low level, and stop the fans in each section in turn for a period of time, each time for about 5 minutes.

If the temperature is too low, reduce the fan speed to a very low level, and stop the fans in each section in turn for a period of time, each time for about 5 minutes. Note that the stopped fan will generally reverse. When starting, start with electric power to reduce the reverse speed before starting.

When reducing the fan speed, generally reduce it uniformly for the entire section.
