Abstract

Mathematical models (MM) for complex research and definition of actions for increase of energy efficiency of the modes of electromechanical system of pump installation of a multystoried house are developed. MM consider changes: a pressure and efficiency of the pump depending on giving and the frequency of rotation; the induction motor’s parameters and losses for various operating modes; optimum(minimum sufficient) value of a pressure of the pump which corresponds to a minimum of losses of energy in hydraulic gates of the consumer. The methodology of definition of coefficient of energy efficiency is developed. The expediency of application of coefficient of energy efficiency when forming laws of regulation of pump installation of a multystoried house is proved. References 11, figures 4, tables 2.

Key words: induction motor, pump installation of the multi-storey building, energy efficiency.
