Question

In a window air conditioner, ............ type of evaporator is used.

• A. Plate surface evaporator
• B. Bare-tube evaporator
• C. Finned evaporator
• D. Both (A) and (B)

Hint:

Fins = more surface area = better cooling in a window AC!

Answer 1

The Correct Option is C

A window air conditioner uses an evaporator to absorb heat from the room air and cool it down.
A finned evaporator is used to increase the surface area for heat exchange.
Fins attached to the tubing help transfer more heat efficiently from the warm air to the cold refrigerant inside the tubes.
This improves the cooling capacity and makes the unit compact and effective.
Plate surface and bare-tube evaporators are used in other systems like cold storage but are not typical for window AC units.
Therefore, the finned evaporator is the correct answer for a window air conditioner.
