In many daily situations the condition of the ambient air does not meet requirements for e.g. a tropical greenhouse, the manufacture of sensitive components or even comfortable offices. The flow velocity, temperature and humidity of the air can be modified by air conditioning systems in accordance with the requirements for the desired room climate.
The trainer ET 600 examines the operation and effect of the individual components of an air conditioning system. ET 600 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 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. The GUNT software provides exact data on the condition of the refrigerant, which is used to calculate the refrigerant mass flow rate accurately. The calculation therefore gives a much more accurate result than measurement using conventional methods.
