PMV output is too low
I run my case to get the thermal comfort results with Fanger, AdaptiveASH55 and AdaptiveCEN15251 model respectively. The zone has air conditioning, operating from 8:00-17:00, with set point 24.5℃. The input for internal heat gains: People can see as below:

which People activity is always 70, WORK_EFF_SCH is 1, WORK_EFF_SCH is 0.5, and AIR_VELO_SCH is 0.2.
But when I get the results of
1.Zone Thermal Comfort Fanger Model PMV
2.Zone Thermal Comfort Fanger Model PPD
3.Zone Thermal Comfort CEN 15251 Adaptive Model Category I Status
4.Zone Thermal Comfort ASHRAE 55 Simple Model Summer Clothes Not Comfortable Time
I found that the during occupied hours the PMV is about -7 and PPD is 100%, which means the it is too cold in Fanger model. However the later two results 3 and 4 are almost 1 and 0 respectively, which means that it is comfortable when the Air conditioning operates.
