Chilled water pipes must be insulated to prevent condensation as well as conserve energy. Many junior engineers don’t quite understand how the thickness of chilled water pipe insulation is determined….
Cooling towers are one of the major components of HVAC. They are used to reject heat in chilled water systems. Many people don’t actually realize the principle behind cooling towers….
When it comes to improving chiller efficiency, the term chiller lift keeps repeating. Chiller lift does affect chiller efficiency. So, what exactly is chiller lift? How does it affect chiller…
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 water…
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…
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….
