One of the options that we have to cool the house in summer are evaporative coolers, some devices that, as we have already seen, try to be a hybrid mix between humidifier and fan achieving small drops in temperature but a higher relative humidity of the air that gives that feeling of freshness.
They are not really a portable air conditioner, although many times they try to sell them as such in store advertising, although in return they are capable of operating with a lower power consumption.
However, with the price of electricity skyrocketing for two years, it will probably cross our minds before we hit the power button on our refrigerators and put them to full operation if it will be very expensive to doespecially if we want to use them for many hours each day.
For this reason, before we get scared with the next electricity bill, we are going to calculate how much it could cost to use this type of device at home, taking into account some previous considerations.
How much does it cost to use our evaporative cooler daily?
In order to calculate the electrical cost of this type of device, we first have to know how much electricity they can consume. It is a data that varies depending on the brands and models but that is usually located in the range of between 50 and 80 watts every hour.
For example, if we review some popular models on the market, we have the Orbegozo AIR46 with a consumption of 55 watts, the Cecotec EnergySilence 2000 with 60 watts, the Taurus Snowfield Babel also with 55 watts, the Purline Ion Rafy 81 that goes up to 65 watts or the Taurus R501 that amounts to about 80 watts.
Taking these examples into account, we will take this value of 80 watts to put ourselves in the worst case of a mid-range model. Also, we will assume that we have it on about 10 hours a day.
With all these considerations, to see the average cost, the first thing we have to do is find out the price for each KWh of electricity that we are going to consume, a figure that varies every hour of the day and that will depend on each electric company, but that we can average with the data of the last weeks and according to what is marked on the website of the Spanish Electrical Network and on the website of the CNMC with a value of about €0.167/kWh (estimated for the first week of summer from June 19 to 25), with taxes already included.
That is, our evaporator will have an electrical cost of 80 watts hour that equals 0.08 kWh that at an average price of €0.167/kWh involves a cost of 0.0134 euros every hour. If we multiply by the 10 hours of daily use we have an expense of 0.134 euros per day.
1 evaporator |
2 evaporators |
3 evaporators |
|
---|---|---|---|
Cost per day (10 hours) |
€0.134 |
€0.268 |
€0.42 |
Cost per month (10 hours per day) |
€4.02 |
€8.04 |
€12.06 |
Cost three months (10 hours a day) |
€12.06 |
€24.12 |
€36.18 |
If we now extrapolate the cost of a whole month by multiplying by 30 days, we get a total figure of 4.02 euros for having one of these devices running every day of the month for 10 hours. If what we want is to see how much it will cost us to use it during the three summer months, we multiply by 3 again and obtain a total amount to pay of €12.06.
Of course, these results are approximate values and will depend a lot on the region in which we live, on the weather, on what do not change the prices of lightetc. In addition, they will depend on the number of refrigerators that we have installed at home, assuming an expense of €24.12 In the case of having two devices or of €36.18 if we have three devices running.
