Box Fan Power Consumption

Power consumption at different air volumes and pressure increases are indicated below.

Cooling fan cpu. P i ideal power consumption w. Let me simplify things for you. Based on our calculations this means that it costs far less than 001 per hour to run making it extremely economical.

The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan. Dp total pressure increase in the fan pa nm 2. Energy usage of about 40 watts at medium speed is typical.

P i dp q 1. As a general rule ceiling fans use less wattage than box fans. Different electrical appliances have different power ratings which show how much energy they use.

The ideal power consumption for a fan without losses can be expressed as. Ceiling fan power consumption is the draw in watts of the ceiling fan on the highest speed excluding the light fixture. Low medium and high settings i measured for power readings.

Fans range in size from 36 inches to 56 inches using 55 to 100 watts a typical 48 inch ceiling fan will use 75 watts. Q air volume flow delivered by the fan m 3 s. When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts.

A 42 inch ceiling fan on low speed uses only 24 watts of power. When calculating power consumption of pc components most consumers fail to factor in case fan power usage. An ordinary ceiling fan would consume more power as compared to energy efficient ceiling fan.

Ac vs fan electricity comparison data. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 watts for 3 hours a day at 010 per kwh. A 36 inch ceiling fan at high speed is still economical at 55 watts.

Power of an appliance indicates the rate at which the electrical energy is converted into the other forms of energy. Notice how much more electricity the ac unit requires to run when cooling even when on low speed. The power consumption of a ceiling fan depends on the size and type of motor used in ceiling fan.

You can see here the power use i observed for the air conditioner left and the box fan right measured in watts. Building a nas or htpc where every watt counts or in high end rigs with. A 52 inch ceiling fan on high speed supplies a tremendous amount of cooling power but only uses an affordable 90 watts of electricity.

That is a common mistake while case fans typically dont contribute much to the power requirements of pc components it does matter in certain scenarios. From top to bottom.
