What are primary-secondary pumping systems?

Many of our hydronic systems used decoupled pumping systems loops to maintain constant primary (plant-side) flows and variable (load-side) flows. How do they work?

Nice Video, watching this 2022 for my project.

Great video !

Hi ...what the mixing equitation formula to take out the water temperature after primery and secondary water mixed...

[@mattyj4564]

Great information, what app do you use to draw out those piping configs... I cannot find anything for the Ipad... I also want to compare a piping problem with my knowledge... thank you.... you cause I don’t know your name

we'll revisit primary-secondary configurations when we looking at system diagrams, if you want more info on the operation of these systems here is some great chilled water plant design guidance: energydesignresources.com/media/2305/EDR_DesignGuidelines_CoolToolsChilledWater.pdf
