DESCRIPTION

The RA2 is a fully instrumented bench mounted air conditioning duct for teaching all aspects of air conditioning systems.

The RA2 duct is a bench top unit fabricated from clear acrylic and mounted on a painted mild steel support frame.

An axial fan moves air through the duct. Heating elements are used to heat the air. Humidification is provided by steam from the boiler.

The steam boiler for the humidifier, the compressor and condenser for the refrigeration system and the electronic control box are all mounted beneath the duct.

Temperature and RH sensors record the temperature and relative humidity at every stage of the operation.

The air flow is measured by an electronic sensor. The mains supply voltage is monitored in the equipment to allow calculation of effective heater powers.
