Ac Fan Only Power Consumption

A typical ac fan motor uses about 500 watts when it s running.

Ac fan only power consumption. Factors affecting the energy consumption of air conditioner. The fan mode for central air conditioning systems is entirely different from the fan mode for window box air conditioning units. There are so many factors which affect power consumption. The power required is 1 2 dav 3 e where d is the air density a is the area of the fan v is the root mean cube average velocity that the fan imparts to the air flowing through this area a and.

The electricity consumption of a. The electricity consumption decreases with use of ceiling fan provided the temperature of the air conditioner is increased in such a way that it provides the right thermal comfort. This page claims the fan motor only consumes 10 of the total power used by the unit but no idea where that figure came from. 1 ideal temperature in an air conditioner higher the temperature that you set lower is the electricity consumption.

We have seen that 25 degree. The fan mode and switches are one such example. Since inverter ac s don t work at full limit once the required temperature is accomplished the blower works at a lower rpm decreasing force consumption. While that s a feature on many air conditioners it s not typically used often.

There are two types of fans ac and dc voltage. Fans can t match the raw cooling power of air conditioning units especially in warm climates but the air circulation provided by ceiling fans or a whole house fan can make a house feel substantially cooler for a fraction of the energy cost of a central ac unit. Posted by cabingirl at 10 08 am on september 28 2008. You re using less power because the compressor is not kicking on which is what uses most of the power.

If ceiling fan is used with air conditioner at the same temperature then the impact is opposite and the air conditioner uses more electricity. Let s also ignore efficiency and power factors because they re immaterial. It may seem logical to think that a fan for an air conditioner is the same as a fan that you use in a room thought this is not the case. Ac fans are more prevalent so let s use that as our example.

This is the basic calculation of ac power consumption. Fan only means the air conditioner is only powering the fan and isn t actually cooling the air.
