An air cooler is often seen as an economical alternative to air conditioning, and that is largely true: its power consumption is significantly lower than that of a portable air conditioner. Below, you can quickly calculate yourself how much an air cooler costs.
Why an air cooler uses little electricity
An air cooler cools the air by evaporating water through a damp filter pad, and uses only a fan motor and a small water pump for this. It does not contain a compressor, like an air conditioner, and that makes a huge difference in power consumption. Most air coolers use between 45 and 75 watts, about the same as a sturdy fan.
Calculate it yourself
You calculate the power consumption with this formula: power in watts divided by 1000, multiplied by the number of operating hours, multiplied by the price per kWh. For a 60-watt air cooler that runs for 8 hours a day, and an electricity price of approximately 0.30 euros per kWh, that comes down to:
0.06 kW x 8 hours x 0.30 euros = approximately 0.14 euros per day, about 1 euro per week.
For comparison: a portable air conditioner with a power of 1,000 to 1,500 watts costs easily 2.50 to 3.50 euros per day with the same operating time, about 15 to 20 times as much.
What affects consumption?
- Settings: an air cooler uses less electricity on the lowest speed than on the highest setting.
- Extra features: built-in LED lighting or an oscillation function adds a little bit of consumption.
- Water pump: this uses hardly any electricity, the majority of the consumption comes from the fan motor.
How much does an air cooler cost per season?
If you only use the air cooler during warm periods, for example 60 days a year and 8 hours a day, you come out to approximately 8.40 euros for a whole summer season with the calculation examples mentioned earlier. That is significantly less than the costs of a portable air conditioner over the same period, which often already come close to 150 to 200 euros.
Important to know
An air cooler is not a full-fledged air conditioner. It cools the air through evaporation and therefore works best in a dry environment; in a humid room you will notice much less cooling. So do not expect an air cooler to cool a room as much as a real (split or portable) air conditioner, but for a few extra degrees of comfort at a low power consumption, it is a good option.
An energy-efficient choice
If you are looking for an air cooler that combines low power consumption with sufficient cooling capacity for an average room, then the Dynter AirFlow SM211 is worth considering. Thanks to the low power, you can easily let it run all day or night without this having much of a noticeable effect on your energy bill.
