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.

Flow Networks system reproduces the problem that usually appears in pressure and flow calculation in pipes that generally have different diameters, lengths and are interconnected; these systems of pipes (in series, parallel or meshed) can complicate the pressure and flow calculation. The flow measurements can be done using the volumetric reservoir of the hydraulic bench (required and not included in this item) and it allows also the study of the relationship between pressure drop and fluid velocity. The module is made of some transparent tubes with different diameters, and it includes a number of valves placed in specific points of the network. The quick couplings used in this system enable fast and easy exchange of pipes creating therefore several network configurations. These pipes interconnections are known as flow networks. For example, a water-supply network of a town or the fire-protection system in a building can be considered as flow networks. With this module, students can perform experiments that can simulate the behavior of the flow network in different conditions.
