The little refrigerating capacity dehydrating unit of a kind of industrial dedusting air-conditioning unit; Comprise high efficiency filter section, return fan, surface cooling section, pressure fan; Said high efficiency filter section, return fan, surface cooling section and pressure fan are through the pipeline series connection; Said surface cooling section comprises surface cooler and electronic ratio adjusting air-valve, and said surface cooler and electronic ratio are regulated air-valve through the pipeline parallel connection.
In the utility model, the air inlet of said return fan is provided with air returning valve, is provided with the high efficiency filter section between said return fan and the said air returning valve.
In the utility model, be provided with roughing efficiency air filter between said return fan and the said surface cooling section.
In the utility model, between said roughing efficiency air filter and the said return fan mixer selector valve is installed, is provided with exhaust valve between said mixer selector valve and the said return fan, be provided with new air-valve between said mixer selector valve and the said roughing efficiency air filter.
In the utility model, the air outlet of said pressure fan is provided with blow valve and Hygrothermograph.
Adopt such scheme, after the workshop dust-laden return air process high efficiency filter section filtering smoke, its air quality reaches indoor discharge standard; So just can be by the principle of traditional air-conditioning secondary return air, return air after filtering and the new wind mixing that adds from new air-valve, portion of air is cooled to below the dew-point temperature through surface cooler; Separate out steam greater than saturated water capacity; Reduce the absolute moisture content and the temperature of air, another part is regulated air-valve through electronic ratio and directly is bypassed between surface cooler and the pressure fan heating from the cooling air that surface cooler comes out, and utilizes the temperature heating of original air to reduce air after the temperature; Thereby replace original post bake; The phenomenon of avoiding cold and heat to cancel out each other, the relative humidity of reduction air reaches dehumidifying, purpose of energy saving.
The beneficial effect of the utility model is; For the industrial dedusting air-conditioning system that temperature, humidity requirement are arranged; The spoke degree reduces the installed capacity of cooling load greatly; The phenomenon of avoiding post bake to cause cold and heat to cancel out each other, thus reach energy-conservation purpose, reduce the initial cost and the operating cost of system.
