When choosing, not only the size of the indoor unit of the air conditioner is important, but also its power, noiselessness, and the availability of additional options.
Selection of the power of the air conditioner
The power of the air conditioner does not need to be calculated, it is indicated on the device itself or in the instructions for it. Cooling capacity and consumption are two different indicators. For example, if a cooling power of 2.4 kW is indicated, this means that the device takes only 0.8 kW from the network - a perfectly acceptable energy consumption. Now it becomes clear why the device is connected to a household electrical outlet and how to choose the right air conditioner.
To understand how the device uses energy efficiently, we introduced the concept of energy efficiency ratio (EER) and it is determined by the ratio of cooling power to consumed. The most productive devices have a coefficient of more than 3.2.
The cheapest are less than 2.2. Now the answer to the question of which air conditioner is better to buy becomes clearer.
Heating function
The ability to use equipment in the "winter-summer" mode will cost an additional 100 conventional units. This is a very convenient feature that should not be neglected, it is clear which air conditioner is better to buy. The air heating mechanism is similar to the cooling process, only now the outdoor unit "collects" not cold, but heat from the street.
Inverter air conditioners
Inverter models allow more efficient use of the compressor power, smoothly regulating it. The noise level of air conditioners of this type is lower, thanks to the inverter system, the device does not turn off completely, it only changes the intensity. That is why the power of such devices is indicated in the range from and to.
It is preferable to choose the technique with the largest range, providing more accurate parameters of the set temperature.
Based on these parameters, the capacity of the air conditioner can be calculated.
Air conditioner noise level
Among the performance indicators of the air conditioner, the noise level plays a major role.
This indicator is measured in decibels and should be no more than 35 for the indoor unit and no more than 53 for the outside.
The size of the indoor unit of the air conditioner does not affect this indicator in any way.
This indicator may vary depending on the mode of operation of the device. Therefore, before choosing the right air conditioner, you should carefully study the instructions, where sufficient attention is paid to the noise level. The most acceptable values for an internal fan operating in three modes are 28 - 30 - 34 decibels.
