The experimental setup represents a real air conditioning and ventilation system. The system capacity is sufficient to climatise a laboratory room.
The air conditioning and ventilation system includes a filter element, a fan with controlled speed, a direct evaporator as air cooler, an electric air heater and humidification by steam humidifier. The following functions are possible: heating / cooling and humdifiying / dehumidifying. For this purpose the active components can be run either manually individually or via a central PLC air conditioning controller in automatic operation. The air conditioning controller controls the temperature and air humidity independent of each other. Via time programs, operation is possible dependent on the time of the day or the day of the week, as in reality. Pressure losses can be measured at each section of the duct.
All common components, such as filter, air heater / air cooler, outlets, smoke detector, multi-leaf dampers, inspection and fire protection flaps are available and can be explained. A standard connection piece in the air duct enables the connection to an external air duct system to climatise an existing room.
The air conditioning and ventilation system consists of three independent system components: main unit, steam humidifier and condensing unit. The connection is performed via hoses. Due to the waste heat the condensing unit should not be placed inside the room to be climatised.
