Copper coils

A/C Copper Coil

A coil is made up of copper tubing with aluminum fins. The cold gas travels through the copper coil transmitting its low temperature to the aluminum fins, which are now chilled.

Return air from the house is filtered and blown through the air conditioner coil fins, which are chilled. The filtered return air is chilled by passing over, under, and around the chilled aluminum fins and copper tubing. The chilled fins condense the moisture out of the return air, much the same as a chilled glass of water. The moisture drips off the fins down to a collector or drip pan, where it is drained away as condensate wastewater.
