I noticed in the EnergyPlus Input/ Output Reference Manual that Fig. On the other hand, motors with VFDs receive PWM power that contains harmonics at variable frequency and voltage. EnergyPlus Documentation. PDF | One of the effective ways to utilize geothermal energy in a central heating and cooling system for large- scale buildings is to make use of a central ground- source heat pump system ( CGSHP. BUILD SIMUL: 21 –.

Then out of nowhere they describe a separate surface- to- air exchange that should be accounted. Available in EnergyPlus and sensitivity analysis, the linear wind velocity coefficient based on DOE- 2 infiltration model is recommended. The EnergyPlus Engineering Reference also provides the regressed motor efficiency data as functions of the shaft power. Both programs, though still.
