Monitoring and Control of a Cooling System in a Commercial Store
نویسندگان
چکیده
This paper presents a case-study for the optimization, the monitoring and the automatic control of a refrigeration system in a commercial store. The existing controllers were replaced by Omron temperature controllers, connected to an industrial network and linked to a central computer for data monitoring and temperature control using a LabView software. In case of an alarm occurrence, this system includes a routine that automatically sends a GSM message to alert the person responsible for the store. This functionality is not yet available in commercial systems. Index Terms — Automation, Monitoring System, Process Control, Programmable Logic Controllers.
