Hydronic balancing is important to the efficiency and effectiveness of chilled water system. However, many engineers find it very difficult to understand. So, I did some intensive studies. Liquid...
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...
