MODES OF HEAT TRANSFER CONDUCTION CONVECTION RADIATION

Heat exchangers are a device that exchange the heat between two fluids of different
temperatures that are separated by a solid wall. The temperature gradient, or the differences in
temperature facilitate this transfer of heat. Transfer of heat happens by three principle means:
radiation, conduction[r]

VENTILATION
The world is ventilated by natural movement of air.
Inequalities of heat distribution drive the climatic air

are generally powerful enough to dilute the pollutants
which we generate. However, pollution due to
