Air conditioning technology is a key topic in building
services engineering. For this reason air conditioning technology plays an
important role during the training of skilled workers and engineers.
The clear trainer represents a complete air conditioning
system with an air duct and a climatic chamber. The main components of the air
conditioning system are the air cooler with condensing unit, fan, steam
humidifier and air heater. Three motorised ventilation flaps control the air
distribution in the air conditioning system. The climatic chamber is equipped
with two different heat sources (wet and dry). Temperature and relative
humidity are measured at relevant points in the air duct and displayed
digitally. For the refrigeration circuit two manometers with integrated
temperature scale and a flow meter provide all relevant measurements.
