Reverse return piping setup is not uncommon in both the chilled water system and hot water system. It promised to provide a balanced hydronic system. But, I'm curious to see if it is true. So, I did...
A sufficient net positive suction head is one of the requirements of centrifugal pumps. Without it, centrifugal pumps will not move water and cavitation may occur thereby damaging the pumps. So, I...
Secondary pumps are very common in the chilled water system. Chillers require primary pumps to move water through their evaporators but why do most chilled water systems have secondary pumps? I'm...
Chillers are one of the most important components in HVAC. They are the heart of the HVAC chilled water system. There are many types of chillers in HVAC and thus, what are the most common types of...
A chilled water fan coil unit is one of the two kinds of fan coil units. It comes in different forms and types. So, many junior engineers are trying to understand chilled water fan coil units. Hence,...
