Experimental identification of structure and parameters of automatic regulators of heating systems

Today the main task of energy saving programs in the country is to provide the efficiency of all processes connected with the production, transmission and consumption of energy. In the utilities sector heat consumption exceeds the consumption of electric energy almost in 10 times in relation to the needs of heating and hot water. In addition the thermal load schedule during the heating season varies greatly (by 5-6 times) not only the time of day, but also on the climatic conditions. Therefore energy efficiency in heating systems by providing them quality control process is an urgent task. The article describes the experience of identifying the regulators flow temperature in heating and hot water. The algorithms and the results of the identification of the three most commonly regulators: ECL Comfort (produced by Danfoss), Vitotronic (produced by Viessmann), 90S (produced by ESBE) used in heating systems and domestic hot water are presented.
