Comparison Ravanson kr-2011 vs Adler AD 7922

The amount of air that the air cooler can pass through itself in an hour.

This parameter depends on the power and the overall level of the device, but there is no strict dependence here: models with the same effective power may differ in air circulation speed. In such cases, it is worth proceeding from the fact that a higher speed contributes to more uniform mixing of air and reduces the time required to create a given microclimate; on the other hand, higher-performance devices use more power, are larger and/or cost more.

The volume of the water tank installed in the air cooler. A large capacity allows you to work longer without adding water, but it affects the dimensions and weight of the device. It should be borne in mind that the cooler the water, the greater the cooling effect and frequent water changes are even beneficial. Also, do not forget that pathogenic bacteria can grow in water if there is water left in the tank and the device is not used for a long time.

The rate at which the air conditioner consumes water. Knowing this speed and the volume of the water tank, you can determine the operating time on a single refill. Also, this parameter can be used to evaluate the performance and speed of the device: the higher the water consumption, the more it evaporates into the air per unit of time. Accordingly, a more high consumption device allows you to achieve the desired humidity quickly.

These are hours of operation per tank filling. It depends on the volume of the tank and the consumption of water. It allows you to understand how long the device can work independently without human intervention.

This mode of operation periodically changes the speed of the fan, sometimes turning it off altogether, creating gusts of wind. Different manufacturers call this mode differently: nature mode, comfort mode, breeze mode, natural, and the like, but they all serve the same purpose.

A device for saturating the air with negatively charged ions. It is believed that the presence of such ions in the air has a beneficial effect on health and well-being, and also creates a feeling of freshness. In addition, ionization helps to reduce the amount of flying dust — it settles faster on various surfaces.

A remote control is included with the device. The convenience of this function is obvious — it eliminates the need to approach the device every time to turn it on, turn it off, etc. Note that remote control, unlike control via a smartphone, is usually only available within line of sight.

The display makes the control of the device more visual. The display can show information about the current operating mode, the set timer, the status of the filter or water tank, etc. Information about the status of humidity and temperature can also be displayed. Displays, as a rule, are equipped with expensive models with electronic control.

The filter cleans the air passing through the air cooler, which not only improves the conditions in the room but also increases the service life of the device. Most models with this function are equipped with mechanical air filters to remove dust, soot and coarse particles. However, there are also coal elements that can absorb odours.
