2.5.2.1. Air quality control
Air quality control is designed according to:
• CO
2
sensor
1
[0...2000 ppm];
• air quality sensor VOCq [0...100 %];
• air pollution sensor VOCp [0...100 %];
• relative humidity sensor [0...100 %];
• temperature sensor [0...50 ºC].
Depending on the type of the selected sensor, the value of the air quality
function to be maintained is set, and the air handling unit intensity will be ad-
justed according to that value. Ventilation intensity will be increased automati-
cally in the case of deviation from the set value and decreased again when it
is approached. For example, if the unit is designed with the CO
2
maintenance
function and is equipped with a CO
2
sensor, after setting value 800 ppm, this set
CO
2
level will be maintained by adjusting ventilation intensity, i.e. ventilation intensity will be increased if
the CO
2
level grows and will be decreased when it returns to the previous condition.
The function of air quality operates only if no other below function is active at the
same time:
• summer night cooling;
• min. temperature control;
• outdoor compensated ventilation.
2.5.2.2. Operation on demand
The air handling unit start-up function is designed to start the unit which
currently o, when one of the selected parameters has exceeded the critical
limit.
The function provided for the start-up of the unit according to:
• room CO
2
sensor;
• room air quality sensor VOCq;
• room air pollution sensor VOCp;
• room relative humidity sensor;
• room temperature sensor.
Operation on demand (start-up / shut-down) is performed by the
same sensor which is used in the control of the “Air quality func-
tion”.
A room sensor with the analogue output (0...10 V DC) should be
designed for this function.
