Abstract

In this study, dynamic control and automation that can be used to save and ensure
the full benefit from the energy used
in central heating
plants application
has been realized. To be able to control in central heating system with the proposed
technique, all the necessary infrastructure were prepared. Then the system controlled with the designed automation
program.  The program has been prepared
for automatic and manual control mode. In automatic mode, the central heating
systems are controlled by the computer system dynamically. The following
information were used for the control as a control input parameters. Heat
exchanger return trip water temperature data, lines' pressure information, circulation
pumps work information, motorized valve information, expansion tank pressure
information, fluid level information, fluid flow of information and knowledge
outside air temperature. PID controllers were used in all
control equipment parts. Curve fitting methods were employed to determine set
values ​​and the waiting time. The realized application has a novelty in
central heating applications if the proposed system is taken as whole with
different aspects. Application of the proposed system provides considerable energy saving, and the results showed that the system increases the efficiency of the heating system. The
widespread usage spread of the system on heating applications
will reduce our dependence on gas imports and will make
a great contribution to economy.
