With the mercury rising, the craving to turn on the air conditioner is at its peak. Paying its bills might seem a minor exchange for the relief it offers. It is always wiser to use intelligent means in order to curb growing expenses. One such wise step would be to calculate how much air conditioning costs. Here is how you can do that
- Understanding Kilowatt-Hours
Kilowatt-Hour is the standard unit to measure electricity in Australia. It reflects the units of electricity your appliance uses per hour. It is mentioned either on the air conditioner’s label or in the manual.
Sometimes, an appliance might have a low purchasing price, but its running cost might make your budget haywire. Therefore, analyse it before purchasing your appliance.
- Note the Energy Tariff Rate
The next step is to figure out the energy tariff rate. It is the cost of every unit of electricity consumed. Your electricity bill will tell you
Multiplying the energy tariff rate with the Kilowatt-hour vector will give you the amount you pay per hour to use your air conditioner.
For example, if your air conditioner consumes 2.4kWh and your energy tariff rate is 33 cents, then you pay 2.4 x 33 = 79.2 cents per hour.
- Observe your usage
The last step is to observe the number of hours you use your air conditioner daily. Multiply the hourly cost to the total number of hours. That will give you your average cost with the utmost precision.
Therefore, if you are using your air conditioner for 10hours every day, the total cost sums up to 79.2 x 10 = 792 cents per day. That is $7.92 a day.
Here is a simple table that you could use not only for keeping a check on your air conditioning but also other appliances.
|APPLIANCE||ELECTRICITY(kWh)||ENERGY TARIFF RATE||USAGE PER DAY(hrs)||COST PER DAY|
Let us have a brief overview to evaluate which air conditioner suits your needs. The estimates are based on the assumptions that the energy tariff rate is 36.5 ¢ per kWh and the average cost of air conditioning is 125 watts per square meter.
- Window AC
This works best for rooms up to 36 sq. meters. The average hourly cost is 12–21¢ for a 12m2room and 42–61¢ for a 36m2room.
- Portable AC
For rooms sized up to 20 sq. meters, this is the ideal appliance. For evaporative systems, the price ranges from 3–4¢ energy, whereas for refrigerated systems it is from 40–51¢.
- Split AC
It works best for rooms up to 75 sq. meters. The average hourly cost is 59–85¢.
- Ductless AC
For your entire house, the evaporative system would cost 27–55¢ per hour. This is ideal for South Australia’s dry climate. The refrigerated system would cost $2.07–$2.59.
This summer ensure that you purchase only energy efficient appliances as they benefit you in the long run. Purchase your air conditioner that is the best for your home and enjoy the cool couch in the hot summers!
