Computerized Air Conditioner Trainer

Computerized Air Conditioner Trainer .
The Air conditioner trainer examines the operation and effect of the individual components of an air conditioning system. Includes all the components also used in building services engineering. Particular importance was placed on the use of original components.

For air conditioning, air cooler (direct evaporator with condensing unit), steam humidifier, fan, air preheaters and reheaters are arranged in an open-air duct. Each of these components can be switched on or off individually. The effect of each individual component on the conditioning of the air is as interesting as the effect of any combination of components.

Sensors record the air temperature and air humidity before and after each stage as well as the pressures and temperatures of the refrigerant. The flow rate of the refrigerant is determined by means of the pressure measurement. The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.
