  • 13

If you cannot or do not want to invest in buying an air conditioner to use, there are alternatives to avoid being hot this summer: you can opt for a portable air conditioner for a minimal installation that you can do yourself or directly bet on buying an evaporative air conditioner, which does not require installation. If you are not very clear about what it is, keep reading because in this evaporative cooler buying guide We tell you how they work, how to make the right choice, and we also offer you a series of interesting models.

How does an evaporative cooler work?

An evaporative air conditioner or evaporative cooler lowers (and already dampens) the air temperature of the room in which it is located. As it does? Taking the air around it and using a cooling fluid for heat exchange: cold water or ice.

A) Yes, the exhaust air is cooler and also more humid, which is why it is especially interesting for dry environments. If you live in a humid area, its effectiveness is less.

This diagram of the De’longhi EV250 evaporative air conditioner (which we will see below, in our featured models) sums it up well:

An important difference between evaporative coolers and portable air conditioners is that the latter do not have air outlet connections to the outside. Everything is inside the device, which is very useful if you do not want to complicate yourself with installationsfor example if you are renting or living in a shared apartment.

As a consequence, with an evaporative air conditioner there is no renewal of interior – exterior air, which is why the room should be properly ventilated to promote air intake.

This way of air conditioning a room is simple, effective and ecological through the evaporation of water, a way in which refrigerants are not used (which contribute to the greenhouse effect) and its energy consumption is also relatively low.

Their maintenance is also lowessentially boiling down to keeping the tank full of water and cleaning/replacing the filters when recommended by the manufacturer.

How to choose an evaporative cooler

  • Deposit size and duration. For cooling they therefore need water, which you will have to place in a tank. Manufacturers offer the volume in liters. First of all, the bigger the better. But more than this data, what is interesting is its application: how long will it work for?

  • Airflow / area. Another piece of information that we are interested in knowing (and that does not always appear in the specifications) is the volume of air that they move per hour. As in the previous case, the more, the better. However, it is easier to know its practical application, or what is the same, for which areas it is recommended.

  • modes. Apart from the different speeds, it may be interesting to bet on models with breeze, night or eco functions. While the former emulates the feel of air current, the latter minimizes noise and the echo is designed to use less power.

  • In general, these are simple solutions and this is transferred to handling: the usual thing is that they have a panel to regulate the modes, but they have remote control it is comfortable and practical.

  • Extras: in general these devices can also function as a fan (forgetting about the water then) and as a humidifier, but there are some that also purify the air with filters and/or ionizers.

  • Design: If they have a large tank and are powerful, it is likely that they will also be bulky and that is something that is not always interesting. In any case, there are some with a handle and wheels so that you can move them and with a certain resistance to water so that you can also place them outdoors, such as the terrace or the porch.
