Description

A kind of escalator energy-saving ventilation system

Technical field

The present invention relates to a kind of escalator energy-saving ventilation system, belong to the innovation and creation of building energy saving field.

Background technology

Building energy conservation has been the Vital Strategic Problems of country." building energy conservation " is listed in " ten large energy conservation projects " with the reform committee by national development, and the building energy conservation target of China is proposed: by pushing forward Building Energy-saving Work comprehensively, 2010, town building reaches the design standard of energy-conservation 50%, and wherein the standard of energy-conservation 65% is implemented in each megalopolis and part big city; Carry out the reducing energy consumption of the existing inhabitation in city and public building; Big city completes transformation area 25%, and medium-sized city completes 15%, and small city completes 10%.On this basis, realize the reducing energy consumption of most of existing building to the year two thousand twenty, new building eastern region will realize energy-conservation 75%, and middle part and western part also will be striven for realizing energy-conservation 70%.

Escalator is a kind of vertical transportation instrument that public building is often arranged.Because escalator is through being normally placed in the crowded occasion such as market, hospital, and escalator keeps geostationary position at each layer, therefore, the position of escalator is just as a passage, due to the existence of hot pressing, the hot-air of heat supply in winter is risen rapidly by escalator position, causes heat losses serious; Summer air-conditioning cold air also can rise by escalator position after entrainmenting ambient heat, causes cold to scatter and disappear serious.Therefore be necessary to arrange air curtain to reduce scattering and disappearing of this hot/cold amount to escalator position, and adopt around top layer escalator hot/cold air scoops is set, arrange in intensive spout directly over the escalator entrance that the air collected is incorporated into the first floor and even each layer again, spout ejection air forms air curtain.Due to horizontal disturbance, after the Air Entrainment heat that spout is sent, density diminishes, risen by passage between escalator again, form a circulating current, these air-flows make the confession of the vertical space volume at the escalator place cooling that warms up not need extra heating and cooling, so be an energy-conservation ventilating system.

Summary of the invention

Basic ideas of the present invention are: the heat supply in winter phase, hot-air always upwards flows, and after particularly entrainmenting the heat of surrounding, atmospheric density diminishes and has the trend of rising; During summer air-conditioning, after cold air entrainments the heat of surrounding, atmospheric density diminishes and has the trend of rising.And the confession of winter and summer warms up air conditioner load all very greatly, therefore, be necessary these to rise to the air re-using that the temperature of top layer is high, reduce energy consumption.Return air inlet and the horizontal arm of return air are set directly over around the escalator of top layer, return air provides power to deliver in the blowpipe of first floor ajutage or other each layers by air-supply standpipe by blower fan, and penetrated by the spout be arranged in directly over escalator entrance, form air curtain.This air curtain plays the effect of heating escalator position air when heating in the winter time, play the effect of isolation escalator position air-flow during summer air-conditioning, winter, summer all have saving energy consumption, improve the effect of thermal comfort.Transition season does not need to open this ventilating system.

The technical solution used in the present invention is: a kind of escalator energy-saving ventilation system, it is characterized in that this ventilating system is managed anyhow by 70 DEG C of fire resisting dampers, ventilation blower, control valve, return air inlet, return air, standpipe of blowing, 70 DEG C of fire resisting dampers, ajutage, spouts form; Return air anyhow pipe connects the return air inlet being arranged in the top of top layer escalator surrounding, before connection air-supply standpipe, set gradually control valve, ventilation blower, 70 DEG C of fire resisting dampers; Air-supply standpipe arrives and locates right-angled bend directly over first floor escalator entrance is horizontal blast pipe, and ajutage is provided with 70 DEG C of fire resisting dampers, ajutage and compact arranged spout connection.Ajutage only can be arranged in the first floor as arm, also can every layer all arrange, equally all to connect spout.

Advantage of the present invention is: the hot/cold air scattered and disappeared by this vertical channel of escalator can be collected by return air inlet by this ventilating system, then delivers to the first floor and send by spout.Longer air circulation jet forms air curtain, the air in escalator region and the air section of its periphery is kept apart.In the winter time, the hot-air of air curtain has the effect in heating escalator region, does not need extra heating; In summer, the cold air of air curtain can make escalator zone air temperature reduce, and air themperature other regions a little higher than in staircase region are acceptables, and therefore, this air curtain does not need extra cooling process yet.In air current composition, as long as be circulating current by this system, just can meet the design temperature requirement in staircase region, therefore, this system is energy-conservation.In addition, owing to can share with pressure air blowing pipe well, also can arrange separately, standpipe to arrange flexibility large, almost can not take architectural plane area.Transition season does not need to open this system, saves fan energy consumption.System is simple, and workable, energy-saving effect is obvious.

Accompanying drawing explanation

It is escalator energy-saving ventilation system schematic diagrams that this description comprises 3 width accompanying drawing: Fig. 1, and Fig. 2 is escalator top level ventilation plane, and Fig. 3 is escalator first floor ventilation layout.In figure: 1,70 DEG C of fire resisting dampers, 2, ventilation blower, 3, control valve, 4, return air inlet, 5, return air manages anyhow, 6, air-supply standpipe, 7,70 DEG C of fire resisting dampers, 8, ajutage, 9, spout.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described.As shown in the figure, a 1. escalator energy-saving ventilation system, is characterized in that pipe 5, air-supply standpipe 6,70 DEG C of fire resisting dampers 7, ajutage 8, spouts 9 form this ventilating system anyhow by 70 DEG C of fire resisting dampers 1, ventilation blower 2, control valve 3, return air inlet 4, return air; Return air anyhow pipe 5 connects the return air inlet 4 being arranged in the top of top layer escalator surrounding, before connection air-supply standpipe 6, set gradually control valve 3, ventilation blower 2,70 DEG C of fire resisting dampers 1; Air-supply standpipe 6 arrives and locates right-angled bend directly over first floor escalator entrance is horizontal blast pipe 8, and ajutage 8 is provided with 70 DEG C of fire resisting dampers 7, and ajutage 8 is communicated with compact arranged spout 9.Ajutage 8 only can be arranged in the first floor as arm, also can every layer all arrange, equally all to connect spout 9.

Directly over around the escalator that the return air inlet of this ventilating system is arranged in top layer, return air provides power to deliver in the blowpipe of first floor ajutage or other each layers by air-supply standpipe by blower fan, penetrated by the spout be arranged in directly over escalator entrance, form air curtain.Air-supply standpipe can be arranged separately, also can use pressure air blowing standpipe, but the arm place of every layer of turnover standpipe all must arrange 70 DEG C of fire resisting dampers.If the air of this air-supply standpipe conveying only plays the effect of air curtain, therefore can not be incubated.But, if use pressure air blowing standpipe, when needing again summer to use, need to carry out Insulation.This air curtain plays the effect of heating escalator position air when heating in the winter time, play the effect of isolation escalator position air-flow during summer air-conditioning, winter, summer all have saving energy consumption, improve the effect of thermal comfort.Transition season does not need to open this ventilating system.
