An Investigation of Air Conditioning System Diagnosis
The current practices to check the health of air conditioning (AC) system at workstations is by the feel of air flow by hands and measuring the air vent temperature by the thermometer. This technique is not accurate enough to conclude whether the AC system performance is satisfactory or not. Hence, there is an opportunity to improve the investigative method and establish a standard procedure to minimize the time required for troubleshooting of AC systems.
The objective of the present work is to check the behavior in suction and discharge pressure and cooling performance of AC systems by simulating the faults on the experimental test rig. A systematic benchmarking study is performed to investigate the problem in the AC system. Major seven defects, which are faced by users, are studied in detail and captured in the work reported. The methodology used for the diagnosis of AC system and the experimental results have also been presented in this paper.
