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.
