When choosing, it is important not only the size of the indoor unit of the air conditioner, but also its power, noiselessness, the presence of additional options.
Air conditioner power selection
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 and consumption power 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 power outlet and how to choose the right air conditioner.
To understand how efficiently the device uses energy, we introduced the concept of energy efficiency coefficient (EER) and it is determined by the ratio of cooling power to consumed. The most productive devices have a ratio greater than 3.2.
The cheapest - less than 2.2. Now the answer to the question of which air conditioner to buy is better becoming more understandable.
Availability of heating function
The ability to use the equipment in 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 mechanism of heating the air is similar to the cooling process, only now the outdoor unit "collects" not cold, but heat from the street.
Inverter models of air conditioners
Inverter models allow more efficient use of 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 equipment with the largest range, providing more accurate parameters of the set temperature.
Based on these parameters, you can calculate the power of the air conditioner.
Air conditioner noise level
Among the indicators of the air conditioner, the noise level plays a crucial role.
This indicator is measured in decibels and should not be more than 35 for the indoor unit and not more than 53 for the external.
The size of the indoor unit of the air conditioner does not affect this indicator.
This indicator may vary depending on the operating mode of the device. Therefore, before choosing the right air conditioner, you should carefully study the instructions, where enough attention is paid to the noise level. The most acceptable indicators for an internal fan operating in three modes are 28 - 30 - 34 decibels.
