Energy saving in electric drives and control of these processes in the sphere of housing and communal services

This article is devoted to increasing the energy efficiency of electric drives of installations of enterprises of housing and communal services, by justifying the use of systems of asynchronous and synchronous drives with frequency converters. It is shown that when throttling, the energy of the flow of a substance held back by a latch or valve does not perform any useful work. The method of solution based on the use of a frequency converter as part of a pump unit is considered, which allows setting the necessary pressure or flow rate, which ensures energy saving and reduction of losses of the transported substance. The results of power consumption, showing the efficiency of the application of frequency-controlled electric drives, are received.
