Quiet Air Conditioner Operation

The compressor and evaporator components are housed in separate units in CITY MULTI and Mr. Slim systems-a design feature that provides the quietest possible operation for both indoor and outdoor environments.

Mr. Slim and CITY MULTI indoor and outdoor units are ideal for applications where quiet is a necessity-libraries, places of worship, lecture halls, classrooms, bedrooms, living rooms, home theaters, and more. Sound pressure levels on Mr. Slim indoor evaporator units range from 19 dB(A) at low speed to 49 dB(A) at high speed; sound pressure levels on CITY MULTI indoor evaporator units range from 22 dB(A) at low speed to 47 dB(A) at high speed. Compare those decibel levels to standard indoor sound levels, which are generally between 45 and 55 dB(A). Mr. Slim and CITY MULTI indoor units emit similar sound levels you'd expect from a whisper, the inside of a library, or the rustling of leaves in secluded woods. And the great variety of indoor unit styles gives you greater flexibility in deciding on the style, from wall mounted to ceiling concealed, to further minimize any unwanted sound.

Mr. Slim and CITY MULTI outdoor compressor units are also quiet-operating from 50 dB(A) (small capacity Mr. Slim compressor units) to about 65 dB(A) (for the larger CITY MULTI modular units). Special care has been taken in the design of the outdoor units to compartmentalize the compressor so that sound is reduced at the source. Specially designed blades and multi-speed motors also reduce system operation sound. The low sound levels allow these outdoor compressor units to be installed near windows, on balconies or near rooftop amenities, giving you back usable space and minimizing disruption to your environment.
