SR-611 Air conditioning system with chamber Educational Equipment Thermal Transfer Experiment Equipment
Description
Comfort is of great importance in the air conditioning of rooms and buildings. The comfort depends on the temperature, the relative humidity and the flow velocity of the air. According to DIN 13779 a so-called “comfort zone” has been defined which specifies the values an air conditioning system should achieve.
SR 611 is a full air conditioning system with comprehensive test options. The effect of the air humidity and temperature on the comfort is examined. The system has a climatic chamber designed for test persons to be inside. This allows the trainee to study the effect of different system operating states on his own well-being. The components used, such as radial fan, electric air heater, steam humidifier and water chiller are all used in commercial air conditioning and ventilation technology. A PLC air conditioning controller monitors and controls all functions. In addition to the automatic operation it also enables the manual operation of the system.
Sensors record air humidity, temperature, power, flow rate, and flow velocity. 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.
