Presentation of control algorithm for cooling system in business building

Abstract

This paper presents an algorithm for controlling and monitoring a cooling system in a business building by using the human-machine interface (HMI). The computer program for automatic control was implemented by using the ©SIEMENS TIA portal computer program. Based on the previously created hydraulic schema of the system, a ladder diagram was created, which was stored in the PLC with the aim of further automatic system control. In addition, a SCADA system was implemented to monitor all the processes of the cooling system under consideration. The control system is designed as a remote-control system with the possibility of adjusting and monitoring the system from a remote location via a computer or mobile device.
