WALL TYPE REGISTERS

WALL TYPE REGISTERS & GRILLES

APPLICATION

Shahrokhi wall type registers & grilles are

designed to suit H.V.A.C. applications where

a high side wall or exposed duct is required.These registers used for adjusting air flow

patterns of airconditioned spaces and yet

with an architectural appearance.Shahrokhi wall type registers & grilles with

one or two way adjustable blades used for

supply, return or exhaust air.

DESCRIPTION

Multi parallel and adjustable blades with

aerofoil section of blades which construct in

one or two row(stage) allow a smooth and

uniform pressure drop applications.Adjustable horizontal or vertical blades can

be supplied to control the air flow pattern in

either the horizontal or vertical planes.

BLADES

Blades may be fixed at any position as

optional during construction which named

fixed type. Either the blades may be moved

at any position which adjust manualy and

named moved type.

FRAME

Four types of frames are available up on

request (figure 2).Select the type of frame is relative to

installation of grilles location.

Three types of blades used (figure 1).Nylon busing or line spring are used to

seperate the blades from the frame to

eliminate rattling and to provide positive

tension when adjusting them.

The (figure 4) shows the air flow pattern for

different blades setting. It is noted that the

throw and drop will decrease as the angle of

the deflection increased.The blades will affect the spread as fallows: a) For 0 deg deflection (straight) angle, the

total spread of the air stream is one-third of

the throw.b) For 22.5 deg deflection angle, the total

spread of the air stream is about 45 percent

of the throw.c) For 45 deg deflection angle, the total

spread of the air stream is two-third of the

throw.

- 0 , 22.5 , 45 are spreading angles (deflection settings).

- Throw is given in feet for 50 F.P.M. terminal velocity.

- All NC levels given are based on10db room absorption.

- All NC, static pressure and AK values given are for single deflection registers with fully open damper and at zero degree deflection.

EGG WALL REGISTERS & GRILLES

APPLICATION

DESCRIPTION

BIADES & FRAME

Shahrokhi egg wall registers & grilles are

designed to suit H.V.A.C. applications where

a high side wall or exposed duct is required.

they are mainly applicable when high air

volume at low pressure is desired.Their attractive appearance make them

suitable for other architectural and

decoration applications.

Multi parallel blades of these grilles adjust

in vertical and horizontal to control the air

flow. These grilles are an aluminium core

which constructed in three types of fixed

egg crate grid opening.

It is possible to fixed at 0, 30 and 45 angles

between vertical and horizontal blades as

shown as (figures 6-7-8).The openings are 0.5" x 0.5" at 0 & 45

angles and 1.8" x 0.5" at 30 angles.

SQUARE GRILLE DAMPERS

APPLICATION

Shahrokhi square grille dampers used for

adjust the air flow rate or close the grilles if

neccessery.The blades of these grille dampers are

construct in two type of parallel or opposite.The levers which used for adjust the parallel

blades are constructable in three types of

receprocating , switch and key.It is possible to contact these levers to an

electrical key or a remote control system

where high side walls or exposed ducts are

not available such as amphitheater, cinema,

etc.Either can be adjust the space optional

temperature by an electrical thermostat

which illustrate in control line.

TERINOLOGY

Aspect Ratio:

The ratio of width to height of the grille core.

Drop:

The vertical distance in feet between the

lower edge of a grille and the lower edge of

the air stream at the end of its throw.Drop is

affected by the lenght of throw the velocity

and the temperature differential between the

supply and room air.

The compressive pressure in inches of H O

that exists in the grille collar area at a given

air volume with or without specific

designated accessories.

2

sStatic Pressure (P ):

The pressure in inches of H O equated to a

velocity that exists for a given air volume in

the grille collar area.

V

2

Velocity Pressure (P ):


The maximum total width in feet of the air

pattern at the point of terminal velocity.

Air Spread :

The distance in feet from a grille or

designated location to a point where the

motion of the air stream is reduced to a

given terminal velocity (V )T

Throw (T) :

The measured velocity at a stated point with

a specified meter. The rated outlet velocity is

typically an average of several prescribed

velocity measurements.CFM = A x V (see outlet Area)

K

k k

Outlet Velocity (V ):

The velocity in FMP of the air stream at the

end of the throw (T) from the grille or a

designated point.

TTerminal Velocity (V ):

A grille sound rating in pressure level at a

given condition of operation , based on

established criteria and specific room

acoustic absorption value. Catalogs NC

ratings are based on sound power level (LW)

minus and 18db room attenuation all actave

bands.
