Abstract:
Based on the principles of mass balance and energy balance, discusses the selection and regulation of the pumps for single heat source distributed hot water heating systems under the design condition, equal flow-rate ratio condition and unequal flow-rate ratio condition respectively, puts forward the method of selecting the pumps according to pump’s impedance, and gives the nomographic chart for pump selection and the formula for pump regulation.
