The trainer comprises an insulated duct through which air is drawn with the help of a fan. The air flow generated is homogeneous due to a specially shaped inlet area. Different heat exchange elements can be inserted into the duct: smooth tubes (WL 312.01), finned tubes (WL 312.02), direct expansion coils (WL 312.03). Velocity distributions and pressure loss are measured with a heat exchanger tube. pitot and an inclined tube manometer. Temperature and humidity sensors included. The following accessories are recommended for the supply of the heat exchanger: hot water bank (WL 312.10), cold water bank (WL 312.11), condensing unit (WL 312.12).
