Injection shutter IJ

The injection shutter is a useful ex­tension for the REMKO PWW unit
and is designed for direct moun­ting on the units.

The supply air is optimally blown in
via the injection shutter. The posi­tion of the air directing fins influ­ences the air velocity and air outlet
temperature of the total air flow.
This technology provides for a hig­her blowing range and more rapid
heating of the rooms.
Intake of the already heated room
air prevents the occurrence of
varying air temperatures. The heat
is distributed evenly throughout
the room.

Installation

Unclip the existing fins and fix the
injection shutter with four screws.
The position of the fins can also be
electrically regulated via an optio­nal control.

Servomotor KSH
(open/closed)

The servomotor is mounted direct­ly on the flap shaft. It is provided
with a universal terminal block and
is fixed with the supplied locking
element.

The drive is overload-proof and
requires no limit switch.
For manual actuation, the gear can

Wiring diagram five-stage control unit 3 EG/5 EG

Five-stage control units,
400V/50Hz, three-phase with
indicator light.
Motor protection takes place
by the connection of thermal
contacts.

In the event of a fault, (operati­on of the thermal contacts), the
internal contactor drops out and
disconnects the motor from the
power supply.

After the motor has cooled down
and the fault cleared, the mode se­lector switch must first be switched
to the “0“ position and then back
to the required operating position
(speed position).

The control units have a connec­tion for external control devices,
e.g. room thermostat, anti-frost
thermostat, servomotor, recirculat­ing pump, indicator light, solenoid
valve, mixer, etc. (observe contact
rating).

Calculation example and explanation

The heat outputs shown in the ratingtables are subject to variation as a result of:

Reduced air volumes with additionally mounted accessories such as
(mixed-air box, filter box, air outlet nozzle, etc.). Observe pressure difference values!

Determination of heat output and air volume when using accessories:

Actual: Unit type PWW 80-3

with filter box FK
with ceiling air outlet nozzle AD
Heating medium PWW 90/70
Air inlet temperature t

= 15°C

1. Determination of the air volume VL (m3/h)

The following data is provided
in the ratings tables (page 30).

Air capacity V = 5400/4300 m
Heat output Q = 50.1/42.7 kW
Air outlet temp. t

this results in an air heating of

∆t = 28/30 K

In the ratio VL to air
volume V (ratings table value), the
heat output factor can be determi­ned from the “heat output factor
correction” f

diagram.

Q

The heat output from the ratings
table multiplied by the factor f

Solution:
Heat output QL = 37.6/28.6 kW

For the calculation example, this results in:

From the ratio V

to air volume V

L

(ratings table value), the air hea­ting factor can be determined.
The air heating from the ratings
table (t

- tL1) multiplied by the

L2

air heating factor fL results in the
effective air heating.

4. Heating medium resistance

Higher speed:

Air volume ratio 0.63 (see above)

Air outlet temperature tL2 = 34 + 15 = 49°C

Lower speed:

Air volume ratio 0.56 (see above)

L

= 30°C x 1.25 = 37.5°C [37°C]
