Blower Intervention

Blower Intervention







The graph below illustrates the solar influence on the blower fan with a constant Y factor and the solar influence changing from 0 to 100%.

Blower power curves

The middle curve illustrates a blower curve without any solar influence. At a constant Y factor of 20%, the solar influence on the IHKA control module will cause the blower curve to shift as the radiation increases from 0 to 100%.

With a solar influence of 0%, curve "B" is used, providing 25% power to the blower.

As the solar influence increases, the curve shifts upward until the solar influence reaches 100%. At this point, curve "A" is used providing 36% power to the blower.

During heating, the blower power decreases as solar influence increases.

While cooling, the blower power will increase as solar influence increases.
