The Noise Of The Air Conditioner.

When choosing and installing air-conditioning should pay attention to noise level, if you are going to install in the bedroom or near the window nervous neighbors, it is necessary to take into account the noise level emitted by the outdoor unit. It is measured in decibels(dB), the sound level to 25 dB is almost inaudible, the level of a whisper is about 25 to 30 dB, the volume of normal conversation and office space – 35-45dB, all the above – loud conversation or busy street. For modern Split systems typical noise level outdoor unit in the range 40-45 dB for indoor unit – 25-35dB. You notice that the volume of the indoor unit does not exceed the volume of the office space, so pay attention to this indicator is when the Installation of conditioners is performed, for example, in the bedroom or a private office.

It would Seem that the choice is obvious, the lower the noise the better and comfort will be guaranteed. But this is not true and it may be that the air with noise level of 25dB will be louder than the other with the figure of 32дБ. And here there is no deception, as modern air conditioning equipment can operate in different modes, and each has its own level. You need to be ready for the split systems can produce other sounds-the gurgling, hissing, crackling, clicks. The gurgling and hissing of the freon may be heard while enabling or disabling of the compressor. Crackling may occur when compression or expansion of the housing parts when the temperature changes. To recognize the internal unit, which emits a crackling, can be cheap plastic that is easy to distinguish from the expensive plastic any other elite models. Clicks can occur when you enable or disable the compressor.

It is Known that the air conditioner need to operate only with the Windows closed, so the noise level of the outdoor unit almost inaudible, but it can be audible to neighbors who do not have air conditioning and all the Windows are open. Of course, the indicator of the serviceable volume of the outdoor unit does not exceed the level allowed for residential areas, but it can irritate the neighbors, so I need to think of the place of installation.
