modelVDI6007
Equivalent air temperature as defined in VDI 6007 Part 1
Extends from BaseClasses.PartialVDI6007 (Partial model for equivalent air temperature as defined in VDI 6007 Part 1).
Information
VDI6007 is a strict implementation of the calculations defined
in VDI 6007 Part 1. The sum of all weightfactors should be one.
