Description
Technical field：
The technical field of the invention is field of heating ventilation air conditioning.
Background technology：
In cold and severe cold area, winter elevator hoistways stack effect is a universal phenomenon, and substantial amounts of cold wind is from the first floor
Entrance, low area's floor crack between a door and its frame and window seam it is isotonic enter interior, cause following influence：
1) cause entrance hall cold wind intrusion volume larger, influence room temperature, thermograde is larger, increase energy consumption；
2) external door entrance critical air velocity is too high, and influence pedestrian comes in and goes out.
3) first floor negative pressure is excessive, influences external door normal switching-off.
4) negative pressure is excessive at lower-level elevator door, and influence elevator door is normally opened and closed, and human assistance is needed when serious.
5) malleation is excessive at high area's elevator door, and influence elevator is normally opened and closed, and human assistance is needed when serious.
6) elevator crack between a door and its frame can produce whistle cry.
At present, for stack effect solution and there is problem：
1) entrance external door uses revolving door, and winter, by conventional vertical hinged door locking, reduces cold wind intrusion.There is problem：Crack between a door and its frame is cold
Wind penetrates into still larger, locking vertical hinged door influence fire-fighting evacuation and goods transportation.
2) glass barrier is added in elevator hall porch, slows down cold wind and enter hoistway.Problem：Influence is current, space-consuming.
3) air conditioner fresh air is increased, is the supercharging of entrance hall.Problem：Increase energy consumption, limited, had not by air-conditioning system condition
It can realize.
4) using the fire-fighting booster fan set at the top of elevator hoistways, winter opens temporarily.Problem：Air-supply is without place
Reason, influence is comfortable, and firefighting fan noise is larger, and away from bottom farther out, large quantity of air can be gushed out top supplying air mouthful from upper elevator mouthful.
Elevator hoistways stack effect is a difficult problem of current high level building, for this condition, proposes the present invention.
Hot pressing neutral plane mathematical modeling is theory as known in the art, for example, exist《Skyscraper hot pressing neutral plane position
Determination》Liu Heqing, China Safety Science journal in August, 2001 volume 11 the 4th is interim to specify that this concept.
The content of the invention
The technical problem of solution：
By the present invention, solve in cold and severe cold area, high-rise building elevator shaft winter stack effect problem.
Technical scheme：
A kind of method for eliminating high rise elevator hoistway stack effect is provided, comprised the following steps：
Step 1: obtaining the mathematical modeling of the hot pressing neutral plane of elevator hoistways stack effect；
Step 2: in elevator hoistways 6, along the bearing of trend of elevator hoistways, being set on a wall of elevator hoistways
Slim airduct 4 is put, blower fan 1 is set at the hot pressing neutral plane of elevator hoistways；
Step 3: setting the initial work parameter of blower fan according to the mathematical modeling of hot pressing neutral plane 3；
Air port 5 is opened up at each floor Step 4: corresponding on airduct, air port area and the pressure difference for opening up tuyere position
The absolute value of value is directly proportional；
Step 5: being set at elevator hoistways bottom inside and outside pressure sensor 2, the elevator hoistways for detecting bottom position
Pressure difference, and sensor is connected with controller of fan, controller of fan adjusts the running parameter of blower fan according to the pressure difference of detection.
Further, hand-operated valve regulating valve is set at each air port, for being adjusted manually to air port area.
Further, described blower fan is ultrathin box-shaped pipeline frequency conversion blower fan.
Further, described running parameter includes air quantity and blast.
Further, controller of fan is brought into automatic building control system.
Beneficial effect：
By this technology, effectively solve in cold and severe cold area, the stack effect of high-rise building elevator shaft in the winter time,
The cold wind intrusion of entrance hall is reduced, so as to reduce energy consumption, is conducive to energy-conservation；Thermograde is reduced, indoor comfort is improved；Improve
The keying of elevator door, eliminates elevator crack between a door and its frame whistle cry.The technology implements succinct, and used unit is received by matured product, small investment
Effect is notable.
