Do primary pumps have more pumping capacity or secondary pumps?
Second can you explain the chilled water piping design in details and different chilled water pumping types?
Different valves are installed at the inlets and outlets of pumps, chillers, FCU, s and AHU, s, So in this regard which standards do we follow?

Hi, thanks for the video. May i know is there any video on common header? because i not understand how the warm water will flow back into the chiller for cooling. Isn't it will become short circuit? thanks

When the pumps are constantly working, how will it know how much load is consumed in ahu or how much chilled water need to bypass through the common header? Plz answer

Is the low loss header installed for the purpose of maintaining the minimum flow rate for the chillers/boilers even though the loading required is not that high?

What happens when the secondary pump fails? Does it shut off water flow to the secondary circuit? Or the main pumps take over?
