Hydronics is a means of heating and cooling using a fluid as the heat transfer medium. Hydronic systems include heating water systems, chilled water-cooling systems as well as some process and domestic water distribution systems. Cooling may be provided by an air-cooled chiller or a water-cooled chiller, and heating is often provided using a hot water boiler. There are numerous pump types for hydronic systems that move fluids, and their construction and operation are dictated by the type of fluid they are moving. In this interactive online course, we will focus on rotodynamic pumps, and more specifically centrifugal pumps, since they are the most common in commercial building systems.

The following key questions are answered in this module:
What are some common types of hydronic systems? Hydronic systems include heating water systems, chilled water-cooling systems as well as some process and domestic water distribution systems.
What are hydronics? Hydronics are a means of heating and cooling using a fluid as the heat transfer medium.
What are the primary parts of a centrifugal pump? The primary parts of a centrifugal pump are the impeller, volute, mechanical seal, drive assembly, and coupling.
What is the impeller? The impeller is the rotating component within the pump that transfers the energy from the drive to the water being pumped.
What are couplings? Couplings are mechanical devices used to connect rotating shafts and absorb minor misalignments between them.
