Experimental Study of Failures of Air Conditioners System Tram in Desert Areas by Applying Preventive Maintenance (Using Reliability Lows)

Abstract

Preventive maintenance is considered the health record of industrial machines and transport vehicles in the world of industry because of its contribution to always protecting these machines and vehicles. Therefore, a tight preventive maintenance plan must always be developed to ensure reliability stability. This article aims to solve the problem of complete failure of the air conditioning (AC) system in trams in the desert region of Algeria, in the context of high temperatures, which resulted in the loss of many passengers and a significant drop in company income. Reliability laws will be applied to the way being obstructed as a result of an error applied in the welding process, which led to the ACHAPS shutdown of the air conditioning system, since the average reliability percentage was 59.01% before fixing the problem and became 81.73% after fixing the problem.
