In the illustrated single zone HVAC system, what prevents the simultaneous flow of steam through the preheat coil and flow of chilled water through the cooling coil? Illustration RA-0009
A
The supply air duct thermostat controlling the steam flow is set equal to the design off-coil temperature associated with the cooling coil.
B
The supply air duct thermostat controlling the steam flow is set several degrees higher than the design off-coil temperature associated with the cooling coil.
C
The supply air duct thermostat controlling the steam flow is set several degrees lower than the design off-coil temperature associated with the cooling coil.
D
Simultaneous steam flow through the preheater and chilled water flow through the cooling coil is permitted for the purposes of space humidity control.
