3: What defines the constant primary and variable secondary circulation system?
The secondary pump only uses the required energy to meet the system demand.
3: What defines the constant primary and variable secondary circulation system?
The secondary pump kicks in if the primary pump breaks down

4: Why is low Delta T a serious problem for a typical pumping scheme?
It reduces the installed chiller capacity at the plant
4: Why is low Delta T a serious problem for a typical pumping scheme?
It causes the system to break down, because of a safety measure
