220V AC Cooling Fan speed control

Time:2014-10-23 Click:443Times

     "220V AC Cooling Fan", with the operation conditions of heat and changed to slow speed operation, the fan will have less noise and consumes less energy.
     In most of the design requirements, the operating hours of the fan speed is lower than the air temperature is generally the maximum design temperature value. Under normal circumstances, low speed cooling fan can be enough to complete its work. However, when selecting and installing should also be considered:
     First, the choice of "220V AC Cooling Fan" must be able to provide enough exhaust volume (speed), under the high temperature of the cooling device inside the hot air; When the temperature is relatively low and less when it is done thermals Instead work.
     Secondly, the choice of the location of the sensor installation should pay attention to the sensor in the proper position, try to make the sensor can be clamped directly to the surface to be cooled. In operation, a temperature-controlled fan will operate at a faster rate if the temperature of the the rmistor at a higher feeling; while at lower temperatures, will be running at a lower speed; these upper and lower middle, the fan speed will almost never due to temperature change.
     When "220V AC Cooling Fan" slow temperature change, change the fan speed is slower, the speed of the fan will not suddenly change and noise. The reaction time depends mainly on the length of its heat-sensitive sensor sensitivity.
