VAVTurndownDuringReheat

Brief Description

When a vav box is in reheat mode, the ratio of v_dot_vav to v_dot_vav_max should be higher than when it isn’t in reheat mode

Index Description

  • Section 6.5.2.1 ASHRAE 90.1-2016

Datapoints Description

  • flag_coil_reheat: VAV box reheat coil operation status

  • flow_volumetric_air_vav: VAV airflow rate

  • flow_volumetric_air_max: VAV maximum airflow rate

Assertions Description

  • if (flag_coil_reheat == False).all():

  • Untested

  • else:

  • ratio_vav = flow_volumetric_air_vav/flow_volumetric_air_max

  • mean_reheat_ratio = df.loc[self.df[flag_coil_reheat], ratio_vav].mean()

  • mean_no_reheat_ratio = df.loc[~self.df[flag_coil_reheat], ratio_vav].mean()

  • if mean_reheat_ratio < mean_no_reheat_ratio:

  • pass

  • fail
