SOUNDS ATTENUATION SOLUTIONS
ADVANCOAT consultants can work with you to design and install a custom Sound Package to specifically reduce chiller noise in sensitive environments. Design engineers specify factory sound jackets to reduce chiller noise based on the chiller’s “sound power”. This does not take into account the mechanical room construction, chiller positioning, and other factors that make up what the whole environment truly contributes, known as “sound pressure”.
The misunderstanding of sound power and sound pressure results in either too much attenuation or too little attenuation. Most factory options only reduce sound power by 3 decibels (dB); noise sensitive applications usually require more attenuation that that. ADVANCOAT can provide custom attenuation from 3 dB up to 20 dB.
Our engineers will analyze the sound pressure of the mechanical room and model its acoustics in order to provide the appropriate amount of attenuation desired. This saves the building-owner time and revenue compared to the exponential prices of installed attenuation equipment.
Proper insulation of cold surfaces is critical for chillers. Poor insulation results in loss of cooling BTUs.
ECT is the best method for the inspection of non-ferrous tubing. It can detect and size defects affecting tubing such as erosion, baffle cuts, pitting, and cracking. It is a nondestructive test technique based on electrical currents interacting with the material being inspected. Most of today’s high efficiency chiller heat exchangers use internally and externally enhanced tubes and thinner tube-wall thickness. These new designs make it is more important than ever to monitor tube condition for corrosion or mechanical wear. This new generation of internally enhanced tubes wall thickness range from 0.019? to 0.028?, which is about 30% to 50% thinner to what was used in older generations of chillers. Internally, enhanced tubes are harder to clean, making them more prone to under deposit corrosion resulting in quicker failures. Periodic eddy current inspections are an important tool to prevent tube failure and possible irreversible chiller damage.
A leak free joint between the tube and tube-sheet is critical for the proper operation of any chiller. Loss of tube-to-tube-sheet joint integrity will lead to water intrusion of the refrigerant circuit causing severe damage to the internal components of the chiller. Failures are usually caused by corrosion and/or erosion of the tube-sheet material, improper rolling of the tubes during installation, and mechanical stresses during operation.
