Online Centrifugal eLearning

HVAC - Equipment and Systems Overview HVAC system components may be grouped into three functional categories: source components, distribution components, and delivery components. Source components provide or remove heat or moisture. Distribution components convey a heating or cooling medium from a source location to portions of a building that require conditioning. Delivery components serve as an interface between the  more...

Centrifugal Pump Fundamentals ...centrifugal pumps is prevalent in many industries. Centrifugal pumps operate on a pump curve whereby the flow rate of the pump increases as the head developed by the pump decreases. Alternately, as the system imposes more back pressure on the pump, the volumetric flow rate of the pump decreases. Thanks to a set of rules called the pump affinity laws, engineers can predict the change in flow  more...
