The invention provides an ultra-high-rise building shuttle elevator shaft cold air supplement and exhaust system, and also provides an air volume calculation method of the system. According to the system, the problems that an elevator door is difficult to close and the wind speed is large are solved. According to the ultra-high-rise building shuttle elevator shaft cold air supplement and exhaust system, one end of an air supplementing air inlet pipeline is connected with the outdoor, the other end of the air supplementing air inlet pipeline is connected with the inlet of an air supplementing fan, the outlet of the air supplementing fan is connected with one end of an air supplementing air outlet pipeline, and the other end of the air supplementing air outlet pipeline communicates with thebottom position of a well channel corresponding to a shuttle elevator; and an exhaust module comprises an exhaust fan, an exhaust air inlet pipeline and an exhaust air outlet pipeline, wherein the exhaust air inlet pipeline communicates with the top of a shaftway corresponding to the shuttle elevator, the other end of the exhaust air inlet pipeline is connected with the inlet of the exhaust fan, the outlet of the exhaust fan is connected with one end of the exhaust air outlet pipeline, and the other end of the exhaust air outlet pipeline is connected with the outdoor.
Description
technical field [0001] The invention relates to the technical field of supplementary exhaust air for elevator shafts, in particular to a cold air supplementary exhaust system for shuttle elevator shafts in super high-rise buildings. The invention also provides an air volume calculation method for the supplementary exhaust system. Background technique [0002] When the chimney effect is strong in winter, it is difficult to close all kinds of doors of high-rise buildings. Among them, the elevator is the most important vertical means of transportation in high-rise buildings, and it is also the channel most prone to safety accidents affected by the chimney effect. When a fire breaks out, on the floors below the neutral plane, due to the effect of thermal pressure, a large amount of outdoor air enters the elevator shaft through doors, windows and orifices, which accelerates the speed of the fire and smoke spreading upward along the shaft, greatly increasing the fire hazard. and c...
