Energy audit of pumps in industrial and municipal systems and labeling of the operational efficiency: systematic approach
(part 1)

Summary

On the basis of a systematic approach, uniform criteria have been developed for estimating the energy efficiency of pumps in real industrial (municipal) systems from the standpoint of environmentally friendly operation in a low-carbon economy. At the same time, the integrated approach of pump manufacturers in tests and designers of real systems with pumps in the process of research and optimization calculations was taken into account. An example is given of estimating the eco-friendly energy efficient operation of a variable-load pump in a municipal system with a time dependent static head component. An example of a typical report of an energy survey is presented based on: the estimation developed for pumps by energy labelling classes for operating conditions in the system, with arbitrary load profiles; a computable structure of the pump design cycle modes with determining the ratio of energy-efficient and energy-consuming operation modes, excess demand energy and taking into account the negative impact on the environment in the form of greenhouse gas emissions in CO2-equivalent. An approach to improving the incentive mechanism for pump operators for the implementation of energy service contracts to reduce the energy intensity of industrial and communal technological processes is considered.
