Test results
Q: In the imaginary scenario, which system is the most expensive?
A: The variable flow system with a constant speed pump
Q: In the imaginary scenario, which system is the most expensive?
A: The variable flow system with a variable speed pump where the pump is operated in proportional differential pressure mode
