<p>The present invention provides a pressurization method to reduce stack effects, and a system for the same to reduce stack effects on an upper and a lower floor in a building at the same time with the use of an existing air conditioning facility. According to an embodiment of the present invention, the pressurization method to reduce stack effects comprises: (a) a step of turning on a winter stack mode when an outside temperature (To) of a building is lower than a predetermined level, and a stack effect pressure difference (ΔPs) is higher than a reference (α); (b) a step of measuring the pressure difference between a room and a common use space; (c) a step of decreasing a ventilation amount (RA) for a set amount (Qs) within a maximum range of an exhaust amount (EA); (d) a step of decreasing the ventilation amount (RA) to be lower than the set amount (Qs) when the pressure difference (ΔP) is higher than zero (ΔP>0); (e) a step of increasing the ventilation amount (RA) to be higher than the set amount (Qs) when the pressure difference (ΔP) is lower than zero (ΔP<0); and a step of repeating steps (d) and (e) to increase or decrease the ventilation amount (RA) in order to turn off the winter stack mode when the outside temperature (To) is higher than a predetermined level or the pressure difference (ΔP) is lower than a reference (Ps).</p> |
