air conditioner part,ventilation muffler

Specifications

Introduction:

the T701 impedance combined muffler expression silencer is makes the resistive sound absorption by the superfine mineral wool, has the good noise elimination effect to the intermediate frequency, the resistant noise elimination is constitutes by in guest section sudden change and to between outer tube's expansion chamber function, to low frequency and partial intermediate frequency noise by effective noise elimination function.

Technical performance

 1, The quantity of noise elimination--when fixed amount of wind, the low frequency noise elimination quantity is 10-15dB (A), the intermediate frequency noise elimination quantity is 15-25dB (A), the high frequency noise elimination quantity is 25-30dB) (A).

2, Resistance loss - - when fixed amount of wind, mean resistance coefficient ε=0.4. Under different wind speed resistance loss according to ε×V2/2g×(mmH2O) computation.

Installation matters needing attention

1. Through the mufflers wind speed should be control, generally the wind speed take 6~8m/s as suitable, if must enhance the wind speed, then may choose 8~12m/s.

2. The muffler may the immediate packing in the air blower air outlet, but installs should be in the system as far as possible approaches using room position, when project for constant temperature system, then the mufflers outer covering should make temperature preservation processing similarly with the air ventilator pipe.

3.Application temperatures in 100 below, and to metal surface non-corrosiveness function situation.
