Roof-Mounted Air Conditioner KK2000 E Design, Task, and Function of the Components (figure 2.4) Condenser The condenser (3) consists of a continuous helical tube and blades that are connected together to a large heat exchange surface. It cools down the hot coolant gas until it liquefies and is undercooled, and it transfers the condensation heat over the blades to the outside air that flows through them. - Page 13 Roof-Mounted Air Conditioner KK2000 E Axial blower The axial blower (4) consists of a direct current motor and fan wheel. Once the air conditioner is switched on, it will constantly be run with board voltage and supply the condenser with the required external air.
