The noise of the air conditioner can be as quiet as a breeze, or it can lead people to headaches and scandals with their neighbors. How to find the quietest air conditioner? What noise level in the apartment do they give out and can sellers be trusted?
How is noise measured?
The unit is decibel. Although the countdown is from "0", but 25 decibels is a noise almost not perceptible to the human ear. This indicator is very important when choosing the quietest air conditioner for a bedroom or a children's room.
Quiet air conditioners for such a room should give from 26 to 36 decibels (indoor unit) and from 28 to 54 decibels (outdoor unit). In the office, you can install a less quiet air conditioner at 35 - 45 decibels.
Many buyers, choosing air conditioners for the bedroom, are chasing the lowest indicator of hum. However, sometimes an apparatus with the promised 32 decibels is quieter than the one with 26 decibels in the instructions. The quietest mobile air conditioners can not be attributed. They give out at least 45 decibels.
Where does the noise come from?
The solution is that any quietest air conditioner has more than one operating mode and there is a different buzz with each of them. The hum from the fan produces a moving air stream passing through the fan, dampers and radiator. So, by minimizing the fan speed, you can achieve the most silent operation. However, even the quietest air conditioner does not work continuously in only one mode. For example, when it gets hot outside, equipment at minimum speed will not cope with cooling. The latest models of quiet air conditioners automatically switch the fan speed if necessary. This is necessary to prevent breakdowns and create optimal conditions for consumers. The more intensive the air conditioner, the more noise it produces. Therefore, one should not rely only on the minimum figure indicated by the manufacturer.
This may be a commercial move and not reflect the real noise level in the apartment after installation.
So, if at different speeds the noise level is 28 - 32 - 35 decibels, the consultant in the store will most likely mention only the first digit of 28 decibels.
Inexpensive models of little-known manufacturers do not belong to the category of the quietest air conditioners for the bedroom. They can sin by gurgling refrigerant or by clicking when switching the relay.
In order not to hear such sounds, do not skimp on the purchase of equipment.
Which air conditioners are the quietest?
To the question: “which air conditioners for the bedroom are the quietest” it is difficult to find the answer, because the equipment is constantly being improved, including in the direction of reducing the noise level.
Among the quietest air conditioners, there are no mobile models. These are just inverter split systems:
- Mitsubishi Electric MSZ - A series of very quiet air conditioners, the minimum noise level is only 21 decibels;
- Daikin FTXS - inverter models with an original design and a noise level of 22 decibels;
- Panasonic CS-E - Inverter systems with a noise level of 26 decibels and a special set of unique filters.
