Q2. What is chilled water coil?

Ans.

A chilled water coil is a heat exchanger used in HVAC systems to cool air by passing chilled water through a coil.

Chilled water coils are typically made of copper or aluminum tubing with fins to increase surface area for heat transfer.
They are commonly used in air handling units, fan coil units, and chilled beam systems.
Chilled water coils work by transferring heat from the air to the chilled water flowing through the coil.
