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.
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.
Display
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.
Air filter
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.
Control
The type of control provided in the device.
Note that
mechanical and
electronic devices can use the same elements — buttons, rotary knobs, sliders, etc. — and as a result almost do not differ from each other in appearance. The difference lies in the fact that the mechanical control directly affects the working part of the device (for example, when the knob is turned, the resistance of the rheostat that regulates the power changes), and the electronic one sends a signal to the control circuit, which accordingly changes the parameters of the device. The advantages of mechanical control are simplicity, reliability and low cost. However, it allows you to adjust only basic functions, and the accuracy of adjustments is low. In turn, with electronic control, various additional features can be provided and individual operation parameters can be very precisely adjusted, but such control is more complicated and expensive. Also, electronic control can be
touch-sensitive, which gives the device elegance and elevates it to a more advanced level.
Cold accumulator
Cold accumulators are used in air the cooling mode. Pre-cooled in the freezer,
the cold accumulators are placed in the water tank of the air cooler unit. The fan of the device draws air from the room and drives it through the filter system, which receives water from the tank. In the process of heat exchange, the temperature of the air decreases. Thus, the work for cooling is implemented for the vast majority of air coolers.
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.
