The mechanical functionality of all components is retained in full. Each of the cutaway models is securely mounted on a base plate to which handles are attached for carrying purposes. The range consists of a series of different cutaway models of drive system components. All components are industrially relevant and have been prepared such that individual active elements are clearly visible to the user. All mechanisms are hand-driven.

Inlet air is cooled and preheated by a heater and latent heat by a humidifier before entering the climatic chamber for demonstration of climate control. The air in the climatic chamber is further heated by a heater and a humidifier before leaving. Recirculation Air Conditioning Unit With Climatic Chamber is a recirculating air conditioning unit with transparent windows and a climatic chamber. A fan after the preheater circulates the air. Part of the air leaving the climatic chamber is vented and the remaining is recirculated with make up fresh air entering the inlet duct. Measuring instruments are provided for air flow rate, and temperature and humidity at various stages. Additional instruments are provided for measurement of refrigerant flow rate, temperature and pressure as well as power for the compressor and heat sources. The amount of air recirculation is controlled by ventilation flaps. Steam generator, compressor and condenser are underneath the duct.
Experiments:
Demonstration of preheating, cooling and dehumidification, humidification, reheating, and mixing processes on psychrometric chart.
Demonstration of refrigeration cycle on Pressure-Enthalpy diagram of the refrigerant.
Determination of recirculating and mixing process of moist air.
Familiarization with recirculating air conditioning system and components.

A three-dimensional stand which consists of three Plexiglas planes has a receptacle for the precision-manufactured models. The associated view can be inserted on each plane of the stand, enabling a direct comparison between the workpiece and the drawing. One shape is made from Plexiglas in order to develop an understanding of invisible edges. The other shapes are made from aluminium. All parts are clearly laid out in a case. The model shapes are precision-manufactured, so measuring exercises can also be carried out. The three-dimensional display is an educational concept for beginners in technical drawing. The student must cut out and fold a template drawing to construct a model. The model set includes ten shapes, involving differing degrees of difficulty. Comprehensive and well structured instructional material makes the training system immediately usable in lessons. For optimal learning, it is recommended that students work independently from each other on these exercises. Two students can easily work with one model set.

The unit consists of the three heat exchangers, and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. The Multi Heat Exchanger apparatus is used for studying of three types of heat exchangers namely-concentric tube, shell and tube, and plate-under parallel or counter flow conditions. The unit requires outside water supply. Changing from one type of heat exchanger to another is by rearranging flexible hoses and changing from parallel to counter flow is by switching two cold water hoses.
Experiments:
Demonstration of heat transfer under parallel or counter flow.
Effects of flow rate and temperature difference.
Demonstration of batch type heat transfer for jacketed vessel.
Comparison of heat transfer coefficients for concentric tube, shell and tube, and plate heat exchanger.
Determination heat transfer coefficient.
Connection toa 12 V transformer enables the volume control by the operating mag- net to bevisually demonstrated.
Further functions:
Emergency-stop valve,
pressure valves,
feed pump,
control travel sensor,
position sensor and pump pistons.
