GEA MATRIX – and there you have effective control of room-air quality
11. March 2010 GEA at SHK 2010, Essen, Germany: the Trade Fair for Sanitation, Heating, Air Conditioning, and Renewable Energies 10 to 13 March 2010, Hall 3.0, booth 144
The GEA MATRIX 400x control system for ventilation units with outdoor-air connection, as well as the GEA MATRIX 4700 for compact and central air-handling units, will be provided – beginning with Version 2.70 – with standard air-quality control functions. This feature is pre-configured at the manufacturer’s plant and is simply activated when the sensor is connected. The operator panel with display will show the current CO2 value, measured in ppm (parts per million). Such an air-quality sensor (e.g., for measurement of CO2 or gas mixtures) makes it possible to continuously adjust the air flow of the connected ventilation units in accordance with room-air quality. The result is reduced energy consumption with high room-comfort levels at the same time.
With the factory setting, the air flap is opened to 100 % when the CO2 share in the room air increases. Then the fan speed is increased. This procedure can be modified, however: with the aid of GEA MATRIX.PC service software, this setting can be changed to enable the air flow to be increased by raising the motor speed and/or by regulating the air flap.
