A cooling system diagram is an illustration of the heating, ventilation and cooling systems within a certain indoor space and outlines the route of air from the intake through the air supply duct. Cooling systems utilize refrigerant coils to cool the air and fans and ducts to move the air, creating thermal comfort and acceptable air quality in a home.
In a cooling system diagram, air is received into the unit through the room's return air duct where it travels through the filter, air handling unit and evaporator coil into the refrigerant coils. The coils feature the fan, condenser coils and compressor, which moves and cools the air. The cooled air is then returned into the room through the air supply duct.
