Pressure gauge

(Exclusively for 2018).

If the air handling unit has filters

installed, they must be equipped

with a visual alarm signal or an alarm

in the control system, if the pressure

drop across the filter exceeds the

maximum allowed pressure drop.

SFPint in W (m

/s)

The SFP Internal calculation is based

on the pressure drop in the following

components:

• Filter pressure drop

• Pressure drop across the heat

recovery system

• Pressure drop across the fans.

For calculation of the SFP Internal, the

air handling unit is compared to a

standard configuration, which is an F7

filter in the supply air and an M5 filter

in the extract air.

By missing or lower filter classes, a

‘penalty’ is added to the filter’s pres-

sure drop. Thus, the actual value is

increased as well as the limit value is

lowered.

Example: If the air handling unit has

an M6 filter in the supply air and an

M5 filter in the extract air, the air

handling unit receives a calculative

‘penalty’, which causes that the pres-

sure drop for the supply air filter is

calculated with 200 Pa.

Thus, the SFP Internal value is incre-

ased, and the limit value is lowered

with 200 points. Therefore, it will be

difficult to comply with the limit value.

This also applies to the extract air

filter. The ‘penalty’ is 160 Pa, if the

filter is missing or the filter class

is lower than M5.

If more efficient filters than F7 and

M5 are selected, the calculation of

SFP Internal is still based on the pres-

sure drop for respectively F7 and M5.

In this way, more efficient filters can

be selected without affecting the SFP

internal.

‘Approved’, ‘Failed’ or ‘Warning’

• If all requirements are fulfilled, the

function is marked as ‘Approved’.

• If one or more requirements are not

fulfilled, the function is marked with

a ‘Warning’ or ‘Failed’

• ‘Warning’ is displayed, if you need

to pay special attention to

something. Usually, to point out that

the fans must be equipped with

variable speed drive (frequency

converter).

• ‘Failed’ usually means that the effi-

ciency in the chosen configuration is

not ok. The air handling unit then

needs to be further optimised.

Total check

‘Approved’ – All Ecodesign require-

ments are fulfilled.

‘Failed’ – One or more requirements

are not fulfilled. The air handling unit

is illegal to install and operate accor-

ding to Ecodesign.
