Introduction
Some diversity standards like DIN 1988-300 define a diversity factor at DHW side, based on the number & type of tapping points, and the total DHW flow. An example is the Based on DIN 1988-300
Option 1 : the user defines the tapping points
diversified flow
If the tapping points are defined, we can calculte the theoretical total DHW flow as a sum of all individual tapping points. We then use the diversity formula to calculate the diversified flow. An example can be found at e Based on DIN 1988-300
The diversified flow is the max sum of flows, taking into account that not all tapping points are used at the same time.
When calculating the diversity flow, we sum up the individual flows without recalculating them (as explained in Step 1 : recalculation of the tapflows). In other words : we calculate the diversity factor for a “standardised“ situation.
Why? because diversity formula’s are inted to express a “probability“, a “statistic chance“ of having parallel tappings. These probabilities are independent of temperature regimes. We call this probability the diversity factor as explained further on.
diversity factor
The diversity factor is defined by the division of the diviersified flow through the theorewtical total flow, and results in a number between 0% and 100%, indicating the maximum “probability“ or “statistic chance“ of having parallel tappings.
Option 2 : the user enters the diversified flow is directly
