Air conditioning systems are the final resort during the hot summer days. They reduce the humidity and make the indoors comfortable for you. A standard AC unit circulates cool air around the room through the vents with the support of a condenser unit kept on the outdoors. The power usage of the unit depends a lot on the temperature level of the region. If the AC is running for about 9 hours in a day, then ideally, it’s using 3000-5000 watts of power for the operation.
This is also important for business projects too. Once you are up with your business, it’s important that you are aware of the business cost including the resource cost.
Efficiency Tip: Look for an energy-star certified qualified model when shopping for a new HVAC unit. If you replace your old unit with an energy-star certified system, you will find a considerate reduction in the electricity bills. Currently, it gives you around 30-40% reduction in the electricity bills, compared to the older models.
How to calculate the power consumption of a standard HVAC?
The calculation is simple once you have all the required information related to power usage and time period. Once you got all the details, the calculations will get easier. Firstly, let’s get a brief intro on the units used for the calculation-
- BTU (British Thermal Unit), is the amount of the heat required to increase the temperature of one pound of water by one Fahrenheit. It indicates the cooling power of the air conditioner, and it’s approximately a third of the watts-hour. 1000 BTU is around 293 kWh (kilowatts per hour). This kWh is usually considered for the billing units for home.
- Total hours used- The total number of hours for which you are using the AC unit.
- Watts per hour- The total watts power usage by the HVAC in one hour.
- Cost of kWh- This may vary depending on the region and the efficiency of the machine.
The formula for calculating energy consumption is given below:
(Total Hours * Watts usage in one hour)/1000 = kWh
Multiply the kWh to the electricity cost of one kWh as per the area:
(kWh * cost per kWh) = Energy Consumption Cost.
And, that’s your answer.
If you are looking for ways to save your expenses, then check out tips like taking a cold shower or using small hand fans wherever possible. Another thing to note, for those who are already living in a hot-humid climate must prefer the energy-efficient system. This gets the cooling and saves your money in the long run!
