Recirculation rate

This sub screen only applies to rooms which are higher than 5 metres (ISSO 57)

Reduction for circulation rate

[Factor] HL
In rooms which are higher than 5 metres, the heating system mainly determines the temperature gradient in the room. The recirculation rate leads to a reduction in this temperature gradient. The corresponding reduction factor can be indicated here; it should be determined based on ISSO 57, Table 2.3 and Figure 2.2.

      Smaller or equal to singular gives a reduction factor of 1.00;

      2-fold gives a reduction factor of 0.75;

      4-fold gives a reduction factor of 0.55;

      6-fold gives a reduction factor of 0.40;

      8-fold gives a reduction factor of 0.30;

      10-fold gives a reduction factor of 0.20;

      User defined: the reduction factor is specified by the user.
