Airconditioning has become a prominent picture in premium segment buses over a decade of time. It has undergone many changes as and when the demand for passenger comfort in public transport industry has raised. Airconditioning is a critical topic influencing the passenger comfort in most of the mass transit vehicles. Transit buses operate in diversified weather conditions especially in country like India across the year, which impose challenge to a single airconditioning system fitted onto bus to provide right airconditioning so the passenger comfort will not be compromised. Airconditioning system has positively increased the comfort level of passengers irrespective of hauling distance or its application for city or intercity transits. Selecting a right airconditioning system for bus application plays a major role in addressing the passenger comfort topic in a broader perspective. This paper discuss on those important area’s which directly impacts the passenger comfort in transit application. This paper discuss in detail onto different stages in airconditioning system selection process, development methods and verification process to evaluate the system against stated requirement while keeping passenger comfort as key objective. It also discusses the critical parameters contributing to the efficiency of the system, heat load calculation & human comfort. The complete study was made on Volvo 8400 vehicle which was then tested for airconditioning pull down test under standard test procedure in static operation condition.
