Detailed description of the invention
Below, with reference to accompanying drawing, the utility model is more fully illustrated, shown in the drawings of exemplary embodiment of the present utility model.But the utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the utility model comprehensively with complete, and scope of the present utility model is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
As shown in Figure 2, the Central air-conditioning unit in the present embodiment is connected to form successively by new wind section 9, initial effect filtering section 2, one-level surface cooling section 10, air return section 11, one-level medium efficiency filtration section 12, secondary surface cooling section 13, bringing-up section 4, fan section 5, humidification flow equalization section 6, secondary medium efficiency filtration section 14 and wind outlet section 8.
By the new wind 15 of prior art is directly mixed with return air 16 in embodiment, become and first dehumidification treatments is carried out to new wind 15, mix with return air 16 again after filtration, decrease the load of surface cooling section, serve the effect reducing Central air-conditioning unit energy consumption.During concrete enforcement, one-level medium efficiency filtration section 12 or secondary surface cooling section 13 can be omitted.Increasing one-level medium efficiency filtration section 12 is preferred version, can improve filter effect, keeps the air entering clean room cleaner.Increasing secondary surface cooling section 13 is also preferred version, and concrete effect is in combination product structure explanation below.
During work, new wind 15 enters Central air-conditioning unit inside by the fresh air pipeline (not shown) be connected with the air inlet of new wind section 9; After initial effect filtering section 2 filters, dehumidified by the one-level surface cooler of one-level surface cooling section 10.
The return air 16 of clean room enters Central air-conditioning unit inside by the return air duct (not shown) be connected with the air inlet of air return section 11; And mix with the new wind 15 after dehumidification treatments.
Mixing air is filtered by one-level medium efficiency filtration section 12, and high temperature season is lowered the temperature through secondary surface cooling section 13; Low temperature season then this section need not work.In the season that temperature is lower, can to freeze intensity according to load adjustment.
Mixing air enters bringing-up section 4, and low temperature season heats mixing air; This section of high temperature season does not work.The season that temperature is higher, can according to load adjustment heater power.
Mixing air enters fan section 5, is pressurizeed by blower fan, and entering humidification flow equalization section 6 increases humidity; After secondary medium efficiency filtration section 14 is filtered, outlet air is met the requirements prescribed.Finally, air is discharged from wind outlet section 8, enters clean room.During concrete enforcement, according to the mounting condition of air-conditioner set, wind outlet section 8 can be omitted.Air is discharged after secondary medium efficiency filtration section 14 is filtered.
By cold for the table of original design dehumidifying section 3 is split as one-level surface cooling section 10 and secondary surface cooling section 13, bear whole dehumidification function by the one-level surface cooler in one-level surface cooling section 10, the rearmounted surface cooler in secondary surface cooling section 13 is only for regulating mixed wind pushing temperature.By arranging two surface cooling sections respectively, two groups of surface coolers are made to bear the cooling function different with dehumidifying two kinds respectively.High humidity only needs to show cold dehumidifying to new wind 15 season; High temperature season only needs to lower the temperature to mist; Low temperature season only needs to heat mist.Namely, when humidity load or thermic load meet the requirement of ventilation state point, corresponding surface cooler of can stopping using, reaches energy-conservation object.
Central air-conditioning unit in the present embodiment is because solving cold and hot situation of cancelling out each other, and the heat exchange area of secondary table cooler greatly reduces; And then making by the air quantity of surface cooler few, windage is little, and operation energy consumption reduces.
Above-mentioned example, just for illustration of the utility model, in addition, also has multiple different embodiment, and these embodiments to be all those skilled in the art can expect after comprehension the utility model thought, therefore, will not enumerate at this.
