Experimental Studies of Energy Systems of Automatic Control Heat Supply of Residential Buildings and Methods of Increasing Their Efficiency

Abstract

Results of trial operation of system of heat supply of the residential building with the optimized processes of regulation of temperature of the heat carrier are given in article. The actual indicators of volumes of the consumed gas for several months 2015 and values of temperature of external air are analyzed. It is shown that "factory" settings of controllers don't ensure effective functioning, especially at temperatures of external air close to 0 °С. The data, which showed that the optimization of processes in heating systems developed techniques for increasing their efficiency by 10–15 %. On the basis of pilot studies in a suburban boiler room with considerable losses in a heating main, the method of increase in their energy efficiency by increase in giving of the heat carrier is offered. The method is realized by means of the converter of frequency installed for control of the network pump. The experiments have confirmed efficiency of the offer.
