Industrial Automation

Client: ICCBS, Karachi University

System: AHUs & Condensing Units

  • Developed programming for S7-1200 PLCs for each Air Handling Unit (AHU) and its corresponding condensing unit to regulate area temperature and relative humidity (RH) by controlling compressors, heaters, and fans. The PLC also monitored system alarms, including refrigerant low pressure, high pressure, electrical thermal overload, AHU fan failure, electrical phase sequence, high area temperature, RH, and loss of room differential pressure. Additionally, a door interlock system for cleanrooms was implemented using the S7-1200 PLC. All HVAC parameters, including alarms, trends, and system graphical user interface (GUI), were displayed on a 10” Weintek HMI as well as on Winlog Pro SCADA software from Sielco Sistemi.

System: Air-cooled Scroll Chiller

  • “Programming of a Fatek PLC and Weintek HMI for the control of an air-cooled scroll chiller with dual compressors. The system incorporates comprehensive safety features, including low and high-pressure trips via pressure transmitters on the suction and discharge lines, water flow loss protection, phase sequence protection, and thermal overload protection for both the condenser and compressors. The control algorithm was designed to manage the operation of both compressors based on the leaving chilled water temperature, while electronic expansion valves were regulated by measuring suction superheat. Additionally, compressor run hours were monitored to prevent overloading. As a result, a fully custom control system was developed for efficient operation and maintenance of the chiller.”
