ZM6157 Air Conditioning System Model Refrigeration Training Equipment Didactic Equipment
* Climatic chamber with latent and sensitive heat source as cooling load1
* Recirculating and outer air operation1
* Optional data acquisition software (.01)1
* Connection options for the use of different automation solutions
2. Technical Description
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.It is operated manually. A key feature of the air conditioning system is that it is fully ready for various automation solutions. The user can thus focus on this important topic during a lesson.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
