Here's an electricity consumption calculator which can help you calculate energy usage in your home. Write CSS OR LESS and hit save. To start we will consider only the effect of a change in the speed of the fan on the flow rate, pressure and power consumption. Enter the exhaust fan wattage, running hours per day and the electricity per unit rate. Power Consumption Calculation Formula. i.e Usha ENERGIA 32 fan consumes 32 Watts for the sweep size of 1200mm. Allowing you to calculate the electrical cost of your home appliances, and helping you save power consumption costs. It means the ceiling fan consumes 52 watts per hour, 1.3 kWh per day, 37.44 kWh per month and 455 kWh per year. Usually, people cut down on their lighting consumption to try and save money, but the thing is, ceiling fans consume much more power than lights if not chosen correctly. The basic unit of measure for electric power is the watt. To calculate the consumption of an electrical appliance in kWh, you have to take into account three factors: the capacity of your electrical appliance, expressed in watt. Refer to ASHRAE 90.1 2007 Usersâ Manual Page G-28 for more explanation of ASHRAE requirements. Table Fan: 10W: 25W: N/A: Desk Fan: Tablet Charger: 10W: 15W: N/A: Tablet Computer: 5W: 10W: N/A : Toaster: 800W: 1800W: 0W : Tower Fan: 60W: 60W: N/A : Treadmill: 280W: 900W: N/A: Tube Light (1500mm) 22W: 22W: N/A: TV (19" colour) 40W: 100W: 1W : Vacuum Cleaner: 450W: 900W: 0W : Wall Fan: 45W: 60W: 0W: Washing Machine: 500W: 500W: 1W: Clothes Washer For an accurate calculation and product recommendation, please input components for an entire system. This should also include the velocity pressure on the inlet side (if known) that is constant and in-line with the fan. Lets calculate the power consumed by a 1.5 ton 5 star rated split a/c operated for 10hrs. Buy copper coil winding instant of aluminium winding. CTRL + SPACE for auto-complete. By that way, we can save 10% of the power. Replace the capacitor once in six months, since a weaker capacitor reduces the speed of the exhaust fan and it causes longer run. Precisely a normal T12 tubelight consumes around 55 watts, whereas a old ceiling fan consumes around 80 to 90 watts. For example, let us consider High-Speed Brijlax PVC Glass Exhaust Fan for Kitchen/Bathroom (Blade Size 150 MM/6 Inches), White (available @ Amazon) and which runs 12 hours per day. (Some multiplication required.) The sir outlet area should be equal to the fan size. Induced Draft (ID) Fan is used to draw the flue gases from the system generated from the combustion of fuel. Calculate Electricity Usage. It is mostly used in the kitchen or bathroom area. But you can get in from amazon page also. While a standard tube light consumes around 55 watts on an average, an old ceiling fan can consume about 80 to 90 watts. Determine the kilowatts an appliance uses per month. Use smaller size mesh, since larger size mesh blocks the outlet air and will oppose the exhaust air. For that, you can install timer and set the ON and off time. P i = dp q (1) where. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 Watts for 3 hours a day @ $0.10 per kWh. Hence the power consumption of exhaust fan per day formula can be written as, E (kWh-Exhaust) = exhaust fan wattage x running hours per day / 1000 For 30 days, To calculate your power consumption, all you need is a simple formula: Calculate the watts each device uses per day; Convert watts to kilowatts. 1 tube light â 40 â¦ Let we calculate the ceiling fan power consumption based on the different manufacturer. The exhaust fan size is available from 5 inches to 12 inches with an average consumption of 70 watts per hour. Energy usage of ceiling fans â¦ Mostly we forget to stop the exhaust fan at the kitchen or bathroom. Write CSS OR LESS and hit save. To convert this to horsepower, you need to divide by 6356. Power Consumption Table. Since the number of watts measured over a period of time (by hours) can accumulate into the tens of thousands, energy consumption is measured in kilowatt-hours â one kilowatt (1kW) is equal to 1,000 watts. (without BEE ratings) Buy plastic blade fan, which consumes lesser power than metal blade fan. Power Supply Calculator. Ceiling Fan Power Consumption is the draw in watts of the ceiling fan on the highest speed excluding the light fixture. hence per day consumption will be, Per day E(kWh-Exhaust) = 70 x 12 / 1000 = 0.84 kWh. For the sake of calculation of energy / power consumption of AC, we will take 3 STAR, 1.5 ton Split AC as reference. You have entered an incorrect email address! Power consumption of 48 inch Crompton fan â 75 watts The power consumption of a fan depends on the sweep (radius) of the blades, the air delivery rate and the revolution per minute of the motor, but to give you a ballpark figure most ceiling fans has rated power anywhere between 60 -100 watts. Even with a reduced motor efficiency of 77.8% and drive efficiency of 86%, with adjust-able speed operation the power required by the fan and the VFD is only 2.8 kW. When calculating power consumption of PC components, most consumers fail to factor in case fan power usage. This will estimate the electricity consumed by each appliance, your overall monthly energy consumption in kilowatt-hours, and the potential savings in energy consumption by â¦ There are 1000 watts in one kilowatt. Enter the total number of operating hours of your ceiling fan, wattage and the per-unit cost. Ceiling Fan Power Consumption: Ceiling fan is available from 32 watts to 120 Watts depending upon the size and number of blades. speed, the fan delivers 50% of its rated airflow but requires only 1/8 full-load power. Energy Use Calculator offers electricity usage calculators for various devices. This tool will help you select a suitable power supply unit for your system. the number of hours that the appliance is in use in one day. Look at the above table, the power consumption of the shorter wings is higher than the longer length. Energy consumption calculation The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt: E(kWh/day) = P(W) × t(h/day) / 1000 (W/kW) The ceiling fan size is available from 400 mm to 1200 mm and the speed from 300 rpm to 2800 rpm. i.e Usha ENERGIA 32 fan consumes 32 Watts for the sweep size of 1200mm.
