My room has HVAC system (Room A) and I have added stack ventilation (monitor at top of the room) to my room (Room B) I would like to know by adding this passive stack ventilation: 1- If Air temperature in room A is 25 °C, it would be decreased by for example 23 °C? 2- If Air speed in room A is 0.8m/s, it would be increased by for example 1m/s?
Or No, because HVAC is controlling the amount of Air speed and temperature of the room. In fact, HVAC keeps thermal comfort in room A and B fixed and passive stack ventilation only contributes to save energy which consumed by HVAC.
Would you please let me know am I right or not?
