Air Conditioner systems becomes more widely into life
With the high-end the office and working environment of continuous
improvement, Duct Air Conditioner systems are also becoming more widely deeply into
daily life. How to make air-conditioning system chosen to play the best results,
in addition to the design reasonable, air conditioning and ventilation works is
also an important factor. Air conditioning and ventilation duct work, as an
important link in the quality of its construction will have a direct impact on
the quality of system installation and operating results. Among the many air
conditioning and ventilation works, due to the wind pipe fabrication and
installation of quality problems caused by insufficient air supply, air leakage
in excess of regulatory requirements, resulting in energy waste, less heat and
air conditioning ventilation engineering operation instability phenomena have
affected the normal operation of air-conditioning.
(1) phenomenon: the plate surface smooth, uniform thickness, with a
clear indentation, cracks, blisters, scarring, and corrosion and other
conditions; duct plane goes down, convex side outwards, with a clear distortion.
2) harm: the system is running, the wind pipe leakage, resulting in Duct Air Conditioner load losses, and affect the life of the wind pipe; air tube surface
vibrate, producing noise.
(3) Analysis: production of duct before, there are no
materials used for quality inspection; do not measure the thickness of steel
plate.
(4) prevention and control measures: First check the material quality of
the materials factory certificate and proof, and then check the material
appearance; measuring the thickness of steel plate.
3.2 Duct distort
and bend angle is not accurate
(1) phenomenon: the two relatively flat
rectangular duct is not parallel, not parallel to the surface at both ends;
CORNER is not flat; diagonal not equal; Seams lax.
(2) harm: make duct
connection Shouli Bu uniform, after installation of the duct is not straight,
flange gasket is not tight, the system leakage, resulting in loss of
air-conditioning load and shorten the service life; impact of the wind pipe,
tuyere the exact installation location.
(3) Analysis: Cutting board not accurate
setting-out; Duct Air Conditioner 22 in parallel, the relative surface of sheet length and
width are not equal; air duct seams, the width of the corners of the office not
equal; seams, seam area set up right, hand-biting Kuchinui force sample sizes;
did not take appropriate measures for reinforcement.
(4) prevention and control
measures: proceed to the next feed, it should be strictly on the sheet metal
angle side of each piece of sheet metal the length, width, and testing the
diagonal, so that their bias control within the allowable range; the next
material sheet after the and should be duct relative surface two sheets coincide
up to test the accuracy of size; sheet metal seams, size must be properly set
aside in order to ensure seams, the width of the same; seams, seam located in
four corners area, manual locking together When sewing with a wooden hammer
first seams at both ends of center of matter, and then evenly along the length
of playing real; implementation of the national standard, "Ventilation and
air-conditioning works and the acceptance of norms" of the relevant
provisions.
