9.2 Introduction to the fan speed controller

210V

60V

27 35 39 42

The low ambient temperature cooling system realizes starting normally at the

temperature -15 by the method of: The sensor collects the coil temperature to change
the voltage of the outdoor fan motor, thus to change the fan speed. As a result, the system
pressure is restricted.

1.When the coil temperature exceeds 42 ,the voltage would be the highest value

210V and the fan motor runs in the normal way. As the outdoor temperature descends, the
condensator temperature descends too, and the pressure of the compressor discharge
lowers. The voltage of the fan motor falls along with the coil temperature. According to the
above chart (the coil temperature descends, the fan speed descends too), when the
temperature falls to 39 , the fan motor runs in the lowest voltage 60V, and if the
temperature falls continuously to 27 , the outdoor fan motor stops.

2.When the fan motor stops, the pressure of the compressor discharge rises

gradually, and also the condensator temperature. If the temperature rises to 35 , the
outdoor fan motor starts and runs in the lowest voltage 60V. If the condensator
temperature can not stop rising, when it is 39 , the fan speed will rise according to the
line in the above chart until the temperature be 42 , and then the fan motor will run in the
normal way.
