Inside the unit under the evaporator coil. The condensate drain line is attached to it.
fan coil unit
A "coil" is a length of copper or aluminum tubing that has been wrapped or folded into a compact package. A refrigerant gas, such as Freon or ammonia, is pumped through the coil by the compressor. Air is blown past the turns of a coil to absorb or reject heat. There are two coils in an air conditioning unit, or any refrigeration unit, for that matter -- an evaporator coil inside (gets cold) and a condenser coil outside (gets hot).
The coil are responsible for transferring of cool air trough the unit
well if your talking about a dx coil in refrigerators and air conditioners there are special chemical cleaners availabe.
the aircondition fan is located in the outside unit of a central AC unit. It sucks outside cool air thru the fins and tubing that contains heat from air collected from inside the house thru the A-coil that's sitting on top of your heating unit. The inside fan in the heating unit blows air thru the cold air moving thru the fins and tubing in your A-coil and blows that air into your house. If you hold your hand above the outside unit while the fan is running you can feel the hot air that's coming from inside, this is how the heat is removed.
to evaporate the refrigerant
To cooling air passing through in room
Yes it does.
FCU means FAN COIL UNIT and ACCU stands for AIR COOLED CONDENSING UNIT
A window a/c is a self-contained unit. The condensor, evaporator and compressor are all in the unit. A split system is the common central air unit you see on most homes. The evaporator coil is located at the furnace withe the system fan, while the compressor and condensing coil are outside the house. This is a simple explaination, but I .
