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?

TT

Every issue of TT features Brain Bee having one Problem Statement. Students have to ponder upon and come up with a most feasible solution and send it to us. Best solution, judged by a panel, gets an exciting prize!

PROBLEM

STATEMENT

Ever witnessed your umbrella blowing inside out on a windy or thunderous day? Design a mechanism, cost efficient, for

the traditional umbrella, for it to cope with the strong wind when the weather goes nuts. Send us the most feasible solution you can come up with to get featured in next Brain Bee and win an exciting prize!
