With decades of experience designing energy-efficient air compressors, we understand the true cost of compressed air. In this article, you’ll learn how to calculate the costs of compressed air – and how to cut them back. How you dry and purify air can also affect the price of an air compressor. How long you run your air compressor and the cost of electricity in your area both can drive up cost. Because the cost of compressed air can be significant, Quincy Compressors offers a free walkthrough to establish a baseline of efficiency, otherwise known as EQ. The EQ rating can help you determine what the cost of operating a compressor will be. One of the first steps for saving costs on compressed air is to find out where you are currently using the air. After Quincy Compressor conducted its unique Efficiency Quotient program for Mega Brands Inc., Mega was able to reduce the cost of its compressed air by more than half.
As we discussed in our Compressed Air Costs: 7 Expenses That Every Manufacturer Should Track blog post, the total cost to own and operate a compressor is generally organized into three groups – the initial capital investment or purchase price, energy usage and maintenance costs. The cost of energy is the single largest expense facing manufacturers who operate air compressors and can account for up to 75% of the compressor life-cycle cost. To calculate the cost to produce compressed air at your plant, use the formula below.
Find out how much your air compressor is costing you with our Air Compressor Energy Consumption Calculator. We created the Air Compressor Energy Consumption Calculator to help you understand what your air compressor is costing you. Use the Air Compressor Energy Consumption Calculator below to understand what the cost of running your unit really is.
Local electricity rates, hose length, machine size, air use requirements of your tools, altitude, temperature, and relative humidity of your work environment all affect energy efficiency – and therefore the cost of your air compressor system. We use a simple formula for calculating compressed air cost. Knowing the cost of your compressed air is the first step to increasing energy efficiency and lowering your bills.
how to calculate air compressor energy consumption Related Question:
How do you calculate air compressor power consumption?
Multiply the wattage by the running time to determine the kilowatt hours used. If a compressor drawing 3,300 watts operates for three hours, it consumes 3,300 watts x 3 hours = 9,900 watt hours. Divide this number by 1,000 to get 9.9 kilowatt hours.
How do you calculate the kW of a compressor?
kW = (A x V x 1.732 x pf)/1,000 Eqn 1 But, you can calculate kW from measured amperage accurately only if you simultaneously measure the voltage and power factor. Or use a kW meter or motor analyzer, which gives a direct kW reading.
How is air compressor efficiency calculated?
A quick estimate of compressor efficiency can be done by taking the ratio of the total loaded hours divided by the total run-time hours. If you find the ratio is very low, say 50%, too many of the compressor hours are spent running unloaded, which is costly and wasteful, and further investigation is warranted.
How do you calculate specific energy consumption?
Generally, SEC is calculated by dividing the amount of energy used with the amount of products.
What is the power consumption for air compressor?
The current draw of air compressors operating with inlet modulation control ranges from about 70% of full-load power to about 105% of rated power. At about 70% of full-load power, no compressed air is generated. At full-load power, about 4.2 scfm per brake horsepower of compressed air is generated.
How do you calculate work done by a compressor?
2.4 Compressor and Pump Models For compressors work is calculated by dividing the enthalpy difference (Δht), from (8), by a mechanical efficiency ( η m c = 97 % ) .
How many kW is a kWh?
1 kWh equals one hour of electricity usage at a rate of 1 kW, and thus the 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is simply kW x time = kWh.
What is energy formula?
The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh. Unit. The SI unit of energy is Joules (J).
How do you calculate energy consumption per kWh?
To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used for. For example, a device rated at 1500 W that’s on for 2.5 hours: 1500 ÷ 1000 = 1.5. That’s 1.5 kW.
What does 2 stage mean on a compressor?
In a single stage compressor, the air is compressed once; in a two stage compressor, the air is compressed twice for double the pressure. By increasing the number of cylinder stages and pressure, these machines work more effectively with a faster recovery time, and can handle more tools at once.
What is compressor efficiency?
The compression efficiency is the ratio of the work required to adiabatically compress a gas to the work actually done within the compressor cylinder as shown by indicator cards (Figures 18-12 and 18-16). The heat generated during compression adds to the work that must be done in the cylinder.
How is electricity unit calculated?
Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
What is the meaning of 1.5 kW?
A kilowatt is a measure of how much power (capacity) a device can provide; kilowatt-hours define the amount of work performed in one hour of time or amount of energy used to do that work. A 1.5 kilowatt (1500 W capacity) kettle will boil the same amount of water faster than a 1 kilowatt (1000 watt capacity) kettle.
