EVAPORATOR COOLER

RANGE OF EXPERIMENTS :

1. To determine Heat transfer rate of heating & cooling.
2. To calculate Effectiveness of Evaporative cooler.
3. The experiments can be conducted at various values of input &

calculation can be made accordingly.

EXPERIMENTAL SETUP :

1. Duct :            500 x 500 x 800 mm Duct in which evaporative coil is fitted.
2. Evaporative Coil :           Hot water is passed through evaporative

Coil made of copper.

3. Air Fan with Motor :           This suction type air fan is fitted on the top

of the duct.

4. Hot water cir. pump :           1/2 HP. 230 V AC hot water circulating

pump is used to circulate hot water into the evaporative coil.

5. Cold water Cir. pump :           1/2 HP. 230 V AC cold water circulating

Pump is used to circulate cold water which spray on the evaporative coil.
