Heating Services Design focuses on the design of heating systems. The book first discusses the fundamentals of fluid flow. Topics include fluid properties, viscous fluids in motion, fluid flow in pipes, and additional losses in pipes. The text explains automatic control and considers feedforward and feedback control, process reaction rate, system time lags, control valves, modes of control, and cascade and multi-controller systems. The book also discusses heating system design; estimation of the heating system load and energy consumption; and steady-state heat losses. The text describes heat emission and emitter selection. Heat emission from pipes, plane surfaces, radiators, and convectors; emitter arrangements; and partial load conditions are underscored. The selection also explains water heating systems. Topics include system layouts; design flow rate and apportioning of the mains emission; sizing the pipework; domestic forms of low pressure of hot water heating systems; pressurized heating systems; and group and district heating. The text is a good source of information for readers interested in the design of heating systems.
