Description
Technical field
The utility model relates to a kind of large space indoor secondary gas flow air-supply arrangement.Be used for the air conditioning area that the air-conditioning air-supply is difficult to arrive, improve the air conditioning area thermal environment.
Background technology
The volumed space building Indoor Environmental Design is in the majority as the comfortableness target at present, as exhibition room building, gymnasium, arenas, Zhongting etc., this class volumed space building indoor occupant zone of action is low, summer in winter, full chamber air conditioning energy consumption was big, for this reason, this class volumed space building adopts the layering air conditioning mode usually, and air current compositions such as the cloth bag of employing air supply mode, following air supply mode are also arranged, to be formed with the air-conditioning in the limit for height degree, reduce air conditioning energy consumption.
When the indoor span of volumed space building bigger, and indoor middle part does not allow to arrange airduct or when being difficult to install, by building side body of wall, the general layering air conditioning mode that adopts nozzle outlet air supply, be difficult to arrive the building middle part owing to the lip jet range is limited, especially when the spout setting height(from bottom) was low, contradiction was more outstanding; For the cloth bag air supply duct then also because of not allowing across indoor and lack scope for their abilities; For following air supply mode, because down air-supply is generally all blown to the middle part by the periphery air outlet, but be difficult to because of air supply velocity is lower cold or heat delivery indoor middle part extremely, little because of its wind speed again, air outlet is bulky, is placed in reasons such as indoor middle part floor space is big and is not usually adopted.Above-mentioned these air current compositions are easy to cause indoor temperature and wind speed inhomogeneous for long span building, thereby reduced indoor comfort, this phenomenon is for the zone of indoor middle part personnel than comparatively dense, and the phenomenon that its comfortableness is poor, indoor air quality is low is just even more serious.
The persuader that is similar to secondary gas flow equipment at present is mainly used in underground parking garage, substitutes ventilation shaft, forms to have the draft of certain tissue in the garage, in conjunction with exhaust system, gets rid of garage internal contamination air, reaches the purpose of improving IAQ; But this secondary gas flow equipment can't be applied to volumed space building, improves the air conditioning area comfortableness.
The utility model content
The utility model provides a kind of secondary gas flow device at large-space large-span building, this device can be installed in the indoor nozzle air-supply range region, also can be installed in the place that air-supply is difficult to arrive, its purpose is to overcome existing nozzle air-supply technology can not satisfy the demand of long span building to environment temperature and wind, avoids because the inhomogeneous caused human body sensory discomfort of indoor temperature and wind speed.The utility model need not airduct, and installation can be according to indoor environment needs chosen position; Also can be lifted on the furred ceiling,, then can be installed on the column if column is arranged by swing pipe.The utility model not only makes its indoor each point temperature wind speed of large-space large-span building reach unanimity, but also can be used as the lamp box advertisement, is specially adapted to mega-exhibition, large-scale arena or large conference room; Easy for installation, the air-supply effect is remarkable.
A kind of large space indoor secondary gas flow of the utility model air-supply arrangement is a kind of indoor middle part that is hung on, and delivers to a kind of equipment at indoor formation secondary gas flow of indoor occupant residential area by suction room conditioning, air-conditioning jet distribution.Can increase indoor air flow and flow, improve the zone of action wind speed, thereby improve personnel's comfortableness; Generally be installed on the jet diffusion zone of once blowing, have the cold that relay once blows and the effect of heat, slow down uncomfortable that the air-flow cold wind sense of once blowing is caused simultaneously; By secondary gas flow equipment flat air-supply jet, also can suppress thermal current rise when using winter, improves personnel activity zone temperature, the effect that cuts down the consumption of energy thereby reach.
A kind of large space indoor secondary gas flow air-supply arrangement, it is characterized in that: a sidewall or bottom at casing are provided with air inlet, another sidewall at casing sets out the air port, air inlet is communicated with inlet air plenum, inlet air plenum is communicated with the inlet of blower fan, fan outlet is communicated with diversion chamber, on the inwall below the fan outlet, be connected with deflector one, diversion chamber is divided into upper and lower two is communicated with cavitys: be i.e. upper chamber, lower cavity, be provided with deflector two between lower cavity and the wind outlet section, lower cavity is communicated with wind outlet section, air outlet successively.Be connected with plate on the wall box at air outlet place, deflector three is connected with hinge with the base of plate, is connected by two arc skid shoes between the two sides, is used to control the size and the air-out angle of air outlet.On casing four sides perpendicular to the ground, except that the sidewall that has air inlet, air outlet, all the other sidewalls are provided with fluorescent tube in the interval of leaving, and form advertising lamp box, and upper and lower surface at interval has opening to communicate with atmosphere, are used to get rid of the heat of lamp box generation.
Described equipment air inlet can be arranged on the bottom of the secondary gas flow equipment vertical with plane, air outlet place, makes air outlet and air inlet in vertical state, also can be arranged on the plane of symmetry with plane, air outlet place, makes air outlet and air inlet be parastate.
Described air outlet is set to flattened rectangular, and making the air-out jet is pancake.
Described deflector one, its position should be lower than the fan outlet lower edge.
Blower fan of the present utility model also can adopt dc brushless motor, and controller is connected with dc brushless motor by lead.Controller can design by software, realizes the control requirement of user to fan delivery.
The utility model is applicable to that volumed space building is difficult to install the occasion of ventilation shaft, especially the intensive central core zone of personnel, secondary gas flow equipment of the present utility model has the effect of air conditioning area and non-air conditioning area up and down that cuts off, its indoor each point temperature wind speed of large-space large-span building is reached unanimity, but also can be used as the lamp box advertisement, be specially adapted to mega-exhibition, large-scale arena, arenas or large conference room; Good looking appearance, easy for installation, the air-supply effect is remarkable.
