Abstract
The invention discloses a seasonally regulating and controlling method for large-space air conditioning equipment capable of changing an air supply direction seasonally. 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.A large amount of volumed space buildings has wherein appearred, as airport building, conference and exhibition center, gymnasium etc.Generally adopt the side air supply mode for the large space air conditioning system, way is spout to be arranged on the peripheral side wall in space,, with the speed of 4～12m/s, the temperature difference of 8～12 ℃ and certain angle jet, make to reflux through the air-flow decay to become popular wet through the occupied zone band.Adopt same blow spray nozzle summer in winter, and winter, the 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, the 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 usually, and this form can be brought the waste heat of upper space into the 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 not only increased the air-conditioning system load, also intercepted light simultaneously and entered in space the energy waste that causes in illumination by transparent ceiling.
For above problem, the mode that adopts from the interior volume air-supply is arranged in the airport building air-conditioning system at present, and (its exploitation unit is called " pass correction card ", have variable air rate, spray the function of blowing), its mentality of designing is that the air-treatment unit is placed on subterranean layer, then the airduct of system, water pipe are passed through the equipment interlayer of subterranean layer, the pass correction card bottom is guided in the air-supply of air unit, then passed floor and blow to indoor by pass correction card.Although this type of design has solved air-supply problem in large space, also optimized the thermograde in large space, have certain energy-saving effect.But such mentality of designing still adopts the mode of the air conditioning area side being sprayed 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, can't realize the theory of layering air-conditioning fully.Simultaneously,, from the angle of the air-supply pipeline of individual air-conditioning system, greatly increased complexity and the resistance of air-line system, the air-supply energy consumption increases.The building box structure is huge in addition, 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 simultaneously air-conditioning system, reduce system energy consumption, and make under meeting air conditioner in bigger space, for warm air-conditioning requirement that space is rationally distributed, to reduce the engineering initial cost be the research contents of this project.
