Sound Attenuation Package
The console equipment is designed to
achieve the lowest noise levels possible.
Extensive testing has identified the
major sound generating sources within
the console unit package. Every effort
has been made to minimize the sound
generation and transmission from the
compressor, heat exchangers, and fan
sources. Vibration transmission from the
compressor and heat exchangers have
been minimized by the use of isolation.
The use of heavy metal gauges in critical
areas enhance the unit acoustic
performance. A patented two-stage
compressor isolation system has been
specifically designed for the console unit.
Acoustic lining has been used to quiet
compressor noise.
The unit airside acoustic performance
has been engineered to obtain the
quietest acoustic performance through
the fan, and fan housing selection. The
fin tube (air-to-refrigerant) coil and fan
discharge arrangement includes an
additional acoustic lining in the fan
compartment to further reduce the
airside sound levels. (See sound
performance data .)
The sound package for the console unit
includes:
