Description
Technical field
The utility model relates to a kind of airhandling equipment, says further, relates to a kind of cooling and dehumidifying type air-treatment unit.
Background technology
For healthy and safe consideration, the laboratory air draft of petroleum chemical enterprise generally has the minimum rate of ventilation requirement about 6 times/hour, and it is bigger that air quantity is mended in needed thus laboratory.Common laboratory has only the comfortableness requirement to indoor environment, and relative humidity generally is lower than 70% and gets final product, and most of laboratories are only controlled indoor temperature; Usually adopt fan coil to add the lower the temperature air-conditioning scheme of cooling processing of wind is mended in the laboratory, perhaps only adopt the lower the temperature air-conditioning scheme of cooling processing of wind is mended in the laboratory, to satisfy indoor temperature requirement.Yet in the bigger area of outside humidity in summer, indoor relative humidity usually occurs and surpass 70%, operating personnel feel the comparison problem of " sombrely ".Its reason is in the laboratory because the use of a large amount of vent cabinet, hood, cause reducing greatly by the heat that spills in the room in analytical test equipment and the analytical test process, add the laboratory operating personnel seldom, make the room, laboratory except that new wind load, other gets heat seldom.When sending into the laboratory to the new wind of dew-point temperature as the processing of mending wind because air quantity is bigger, indoor heat seldom, the new wind-warm syndrome liter that causes sending in the room is very little, makes indoor relative humidity higher.
For the problems referred to above, need the air-conditioning system that adopts temperature, humidity independently to control.Wherein, methods such as freeze drying, solution dehumidification, solid dehumidifying, dry type dehumidifying and mixing dehumidifying are arranged at present to the control of humidity.Wherein solution dehumidification, solid dehumidifying, dry type dehumidifying and the mixing dehumidifying that contains above-mentioned dehumidification mode, all need regeneration, and equipment more complicated mostly, narrow and small and general occasion all lacks that use can be subjected to certain restriction under the condition of the thermal source of regenerating summer in the machine room space.Method for independent employing frozen cooling dehumidifying can't address the above problem.
By retrieval, have and the similar airhandling equipment independently controlled of temperature, humidity of the utility model, all adopt the water-cooled coil pipe basically, perhaps two low-temperature receivers of Cai Yonging, promptly the water-cooled coil pipe adds direct-expansion coil and cools off and dehumidify.The laboratory of petroleum chemical enterprise is generally all independent to be provided with, and does not in most cases have outer cooling source to be used for cooling in summer; Its construction area neither be very big, adopts handpiece Water Chilling Units or two low-temperature receiver to cause system complex, and investment and operation are also uneconomical.
(CN101354163A, denomination of invention: a kind of new blower fan group) disclose: new blower fan group comprises fan section, flow equalization section, middle effect and inferior efficient section and shows cold, heat and air supply section again Chinese patent.This unit is in the cooling in summer dehumidification process, and the water cooling coil cools, with direct vaporation-type coil pipe dehumidifying.What this new blower fan group adopted is two low-temperature receiver coil pipe, i.e. water-cooled coil pipe and cold-producing medium coil pipes.Must there be extra chilled water system that the chilled water of the usefulness that cools is provided for the water-cooled coil pipe.Little and when not having external chilled water supply when architectural scale, because it is many that the required equipment of chilled water system is set, take up an area of big, system complex, also uneconomical in the operation, generally all adopt direct vaporation-type air-conditioning system.The new blower fan group of this kind just can't be used in this case.
The utility model content
For solving problems of the prior art, the utility model provides a kind of cooling and dehumidifying type air-treatment unit, can be under the condition of not using external source and thermal source, and only the compression refrigeration by self realizes the function that temperature, humidity are controlled simultaneously.
