Recommended room area
The area of the room for which the device is designed. This paragraph indicates the maximum area that this model can effectively serve: the use in smaller rooms is quite acceptable, but the device simply does not have enough performance for a larger space. We also note that the area is indicated based on a ceiling height of 2.5-3 m — the standard value for residential premises; with a higher ceiling height, the effective area decreases, and it can be recalculated using special formulas.
When choosing by area, it is worth taking a certain margin, but it should not be too large — otherwise, the device will turn out to be unnecessarily powerful, bulky and expensive.
Air circulation
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.
Water tank volume
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.
Humidification water consumption
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.
Wind simulation
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.
Auto-rotate blinds
Automatic blind position adjustment is used in air conditioners to ensure uniform distribution of outgoing air flows. As a result, fresh and clean air penetrates into all corners of the serviced premises.
Power consumption
The maximum power consumed by the device during operation. The lower it is the more economical the device. It should be noted that operation in the heating mode is highlighted as a separate item, but here it is indicated in the normal mode.
Noise level
The maximum noise level generated by the air cooler during operation. Most of these devices are used in residential areas, so this parameter should be treated carefully. According to sanitary standards, constant noise in such rooms should not exceed 40 dB (quiet conversation) during the day and 30 dB (wall clock ticking) at night. More detailed comparison tables and recommendations can be found in special sources. It is also worth mentioning that the noise level is indicated for the maximum operating speed, so the noise level will be significantly lower in reduced mode.
