Chiller efficiency is one of the most discussed topics among HVAC engineers. However, chiller efficiency is represented in many different units of measurement and certain units may not be stated on...

Cooling towers are one of the major components of the chilled water system. Many people encounter the blowdown valve of cooling towers but they're not entirely sure why it is needed. So, I did some...

Pump head is an essential parameter for chilled water pumps as well as condenser water pumps. It determines if the pumps are able to deliver the required water flow rate. So, how do you calculate the...

Chiller surge is a problematic behaviour in buildings that are equipped with a chilled water system. Operators and engineers are having a hard time figuring out why chiller surge is happening. So, I...

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...

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. So, how cooling...
