3 - Table of maximum working flow rates
3 - Choose the thermostatic mixing valve that will ensure regulation at this instant flow rate, under the available dynamic pressure
(b. = bar) for its operation (table below).
SIMULTANEITY COEFFICIENT (K) depends on the type of work and the number of taps to be supplied.
We consider 3 types of work:
- stadiums gymnasiums- factories schools swimming pools army barracks
- guest houses campsites hospitals spa installations
- accomodations
