The sequence of PPD index of this experiment was presented in Fig. 5. The X axis is time in sec., the left Y axis is the value of PPD index, and the right Y axis d. In the duration of 0 to 2 minutes, the heat radiator turned on, and the PPD index changed from 5% to 95% rapidly. In the duration of 2 to 4 minutes, the value of PPD index was between 30% and 95% when d=100 cm. Consequently, it went to the next 2 minutes. the value of PPD index reduced between 10% and 20% when d=150 cm. In the duration of 6 to 8 minutes, the value of PPD index reduced between 5% and 10% when d=200 cm. Finally, in the duration of 8 to 10 minutes, the value of PPD index was around 5% when d=250 cm. |
