Download or read book Variable Speed Pumping in Heating and Cooling Circuits written by C. J. Parsloe and published by . This book was released on 1999-05-31 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume sets out a methodology for the design of heating and cooling systems with variable speed pumping, systems where pump speed is varied in response to changing heating or cooling demand. The outputs from terminals are normally varied by the throttling action of two-port control valves. Pump speed is then controlled to match the water flow requirements of the terminals as closely as possible. The book offers a step-by-step design procedure, explains the theory underlying the design procedure and describes the alternative solutions which might be considered.
