A seasonal direction change air supply way is adopted, the purposes of up-supply down-return in summer and down-supply up-return in winter are realized, and the indoor temperature field distribution is optimized through combination of air flow convection at different temperatures. According to the invention, one or more air conditioning equipment capable of changing the air supply direction seasonally is adopted to replace a whole ventilation and air conditioning system, so that the system is simplified, the energy consumption of an air supply system is reduced, the material consumption and initial investment of the system are saved, meanwhile, a plenty of space such as an air-conditioner room, an air conduit interlayer and the like for mounting the air supply system is saved, and the use ratio of building space is increased.
Description
Technical field
The present invention relates to the regulate and control method in season of the seasonal commutation of a kind of large space air supply air-conditioner device.
Background technology
Along with the quickening of China's city process, building industry has obtained unprecedented development, and building multi-form, Various Functions is built in a large number.Wherein there is a large amount of volumed space buildings, as airport building, conference and exhibition center, gymnasium etc.Generally adopt side air supply mode for large space air conditioning system, way is the peripheral side wall that spout is arranged on to space, with the speed of 4～12m/s, the temperature difference of 8～12 ℃ and certain angle jet, making to reflux through air-flow decay becomes popular wet through occupied zone band.Adopt same blow spray nozzle summer in winter, winter, indoor temperature field distribution was inhomogeneous because thermal current rises, and stream of people behaviour area temperature is on the low side, causes air-conditioning effect poor; As configuring automatic control system, initial cost cost is high, and adjustable range is little.
But for the larger space of span, both sides are inadequate to spray spout range, and way is that spout is arranged in roof grid frame conventionally, and this form can be brought the waste heat of upper space into occupied zone face, increases the load of air-conditioning system, is unfavorable for energy-conservation.
Take the terminal on modern airport as example, most of public domain is open large space, can not meet the air-conditioning demand of such building by above two kinds of air-conditioning ways.These two kinds of ways often can not adapt to the demand of the high spatial layout of modern and open, and spout is installed on roof grid frame has not only increased air-conditioning system load, have also intercepted light simultaneously and have been entered and in space, caused the energy waste in illumination by transparent ceiling.
For above problem, (its exploitation unit is called " pass correction card " in airport building air-conditioning system, at present the mode adopting from interior volume air-supply, there is variable air rate, spray the function of blowing), its mentality of designing is that air-treatment unit is placed on to subterranean layer, then the airduct of system, water pipe are passed through to the equipment interlayer of subterranean layer, the air-supply of air unit is guided to pass correction card bottom, then blow to indoor by pass correction card through floor.Although this type of design has solved air-supply problem in large space, has also optimized the thermograde in large space, has certain energy-saving effect.But such mentality of designing still adopts the mode of air conditioning area side being sprayed to air-supply, just utilizes pass correction card that large space is divided into less air conditioning area, and winter and summer utilizes the angle of spout to regulate air supply direction, cannot realize the theory of layering air-conditioning completely.Meanwhile, from the angle of the air-supply pipeline of individual air-conditioning system, greatly increased complexity and the resistance of air-line system, air-supply energy consumption increases.In addition building box structure is huge, and not only cost is high, the utilization of also having wasted space simultaneously.
How effectively to solve the large space problem of blowing at a distance, realize the layering Air-conditioner design of large space, simplify air-conditioning system simultaneously, reduce system energy consumption, and under meeting air conditioner in bigger space, for warm air-conditioning requirement, make that space is rationally distributed, to reduce engineering initial cost be the research contents of this project.
