Abstract: Air conditioning cabin of a transport truck is a new concept in India and has not been addressed. But in summer, the temperature in some parts of India is very high and results in unbearable cabin temperatures. In such conditions, an air cooled cabin for transport truck is a necessity. It is observed that much work has not been done in the field of cabin cooling of transport truck. The available options in heat generated cooling have been critically reviewed. The vapour absorption refrigeration cycle is found to be suitable for automobile air cooling especially for transport trucks. The heat potential in the exhaust has been analyzed and found to be sufficient enough for powering the proposed air conditioning system. The significance of the work is that it will provide space cooling for the truck driver and thereby enhances his performance and efficiency without affecting performance of the engine essentially the fuel economy. Further the vapor absorption cycle use non CFC refrigerant and thereby have little effect on environment. The present work is focused towards the design and development of an air cooling system for the cabin of truck using waste heat from exhaust. This document gives information about how much important is waste heat and using this we can develop a refrigerant system without taking input from battery, also design is developed based on vapour absorption refrigeration system which demands for future. In this article, we design different parts of the system and there basics behind this. Also, we study thermodynamic analysis of ammonia vapour absorption refrigeration system. From this we can concluded that the power required is less as compare with vapour compression refrigeration system and also study advantages over this.

Keywords: Vapour absorption refrigeration system, COP, Thermal conductivity, Generator, Ammonia, Absorber.
