Car can be equipped with Vapour Absorption Refrigerant System. Its basic objective is to cool
the space inside the car by utilizing waste heat from silencer.
In a Vapour Absorption Refrigerant System,
a physicochemical process replaces the
mechanical process of the Vapour
Compression Refrigerant System by
using energy in the form of heat rather
than mechanical work. The heat required for running the Vapour Absorption Refrigerant
System can be obtained from that which is
wasted into the atmosphere from silencer of vehicle. Hence to utilize the exhaust gases and waste heat from a silencer the vapour absorption refrigerant system can be put into practice which increases the overall efficiency of a car.
There is a high amount of heat continuously generated in the silencer. Therefore silencer works as a heat exchanger for vehicle in vapour absorption system. This heat exchanger provided
between the absorber and analyzer is used to convert strong solution (water + ammonia) in analyzer to vapour form and is then passed to the condenser. Cycle then continues.
Applications
1. The constant availability of ice and cold drinks.
2. To store and preserve perishable food.
What can be different ways in which
heat lost through silencers of vehicles can be utilized?
