Detailed Description

Calculates the thermal comfort quantities predicted mean vote (PMV), predicted percentage of dissatisfaction (PPD) and the draught rate (DR) based on DIN ISO EN 7730:2005.

The draught rate is defined for velocities between 0 m/s and 0.5 m/s. Values larger than 0.5 m/s will be set to 0.5 m/s. Furthermore, the draught rate is defined between 20 degC and 26 degC. A temperature limitation is not implemented. The draught rate is mainly used for HVAC analysis in rooms.
