Fig. 7.54 Outdoor weather conditions with temperature profiles of thermal
zone “1SS2”
Figure 7.55 shows the ventilation rate and supply air temperature of the
1SS2 zone. The ventilation rate is about 0.2 air changes per hour (ACH),
but between 6 P.M. and 6 A.M., the ventilation is turned off. A CO 2 sensor
can override the ventilation flow rate. The measured average supply air
temperature is about 18.9 °C.
