Abstract

In the first (theoretical) part of the dissertation is solved heating industry in general and the types of heating systems. Examine the pros and cons of various types of wiring the heating systems. Also describe pumps, namely hydrodynamic pumps. In the practical part I deal with the actual accumulation of energy in Tichelmann connection. First I determine the optimum temperature to which should be preheated hot water distribution. I also specify the operation points to the pump, and finally count the actual time after which the relay station is operated to achieve the accumulation of thermal energy to the branch hot pipes preheated to the desired temperature (with regard to the possibilities of the control system and the conditions of the regulation and protection will be used for the calculation always the value 85°C). This is all done for both winter and summer pumps. Finally, I evaluate the feasibility of accumulation and possible adjustment of the heating system. The theoretical results will be compared with the facts in the transfer station SPC 3 with the help of parameters measuring media.
