1. Determination of the air volume V

/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

= 43/45°C

this results in an air heating of

∆

= 28/30 K

The individual pressure difference values D

(see page 31) are added:

Filter box FK 7

Air outlet nozzle AD 9

Total difference = 16

Solution from the diagram:

= 3400/2400 m

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

Required: Air volume V

/h)

Heat output Q

(kw)

Air outlet temperature t

(°C)

Heating medium resistance ∆p
