"Their energy consumption is similar to that of

, that is,

of a typical air conditioner," the specialists highlighted in a recent article titled

of water," they explained to

from

, one of the brands that offer them in Argentina.

"The equipment -they detail- takes the

air from the environment,

it through

with water (natural or cold) and automatically cools the air due to the evaporation of the water."

The temperature of the air drops as it passes through the appliance because the water on the grill, evaporating,

.

And the low energy consumption is due to the fact that, for this to happen, the equipment only uses a fan and a small water pump.

Where does the water that constantly moistens the filter come out?

From a

or reservoir that the user, every certain number of hours, must take care of

.

There are small coolers that hold

On the other hand, unlike an air conditioner, the air conditioner

of the room.

And, although unlikely, the water could eventually spill over.

"

is much more expensive and consumes more electricity, but it achieves a much greater drop in air temperature," they compared from Midea, which also offers air conditioning.

And they added: "Those who choose an evaporative cooler pay

, but they understand that it offers an additional benefit (

), which, without reaching the cooling that an air conditioner produces, is somewhat

. "

How to get the most out of an air conditioner: practical advice

1. Better, in small spaces

.

They achieve a greater reduction in temperature.

2. Open doors and windows

Contrary to a traditional conditioner, the system works best if air circulation is allowed.

We must avoid the accumulation of moisture.

3. Clean the wet rack periodically

.

Also the water tank, to prevent dirt from collecting.

4. Renew with clean water periodically
