WL 312.03 Heat Exchanger Element Direct Expansion Coil Show data sheet (pdf file) Print page
Technical Description

The WL 312.03 heat transfer element enables investigations to be performed on a refrigerant evaporator in the WL 312 trainer. For this purpose the component is inserted in the air duct in the base unit using quick-release fasteners. The refrigerant connections on the evaporator are self-sealing so that no refrigerant can escape. The WL 312.12 condensing unit is necessary for the operation of the evaporator. Refrigerant condenser and evaporator together form a complete refrigerant circuit. The temperatures at the evaporator inlet and outlet are measured using thermometers.
