Description
Technical field
The invention belongs to air handling system design and manufacturing technology field, be related to one kind can be provided for architecture indoor it is low
The air processor of wet environment.
Background technology
In current air conditioning device design and manufacturing field, it is civilian to mainly focus on public building and home dwelling etc.
The construction of the Indoor Thermal Environment of building, and the related air-conditioning products for industrial building are not also very abundant.And right work
Industry building is again often more harsher than civil buildings for the demand for control of hygrothermal environment, this makes air-treatment common at present
Equipment is difficult to meet its specific demand.
In industrial building, many craftsmanship productions, processing occasion have stringent want to indoor temperature and humidity, cleanliness factor etc.
It asks, Indoor Thermal Environment regulation and control are to ensure the important link of industrial technology production requirement.Due to industrial products numerous types, institute
It is required that indoor production environmental difference it is very big.For example, the indoor temperature and humidity of electric wire manufacturing shop require to be 27 DEG C of temperature and
Relative humidity and water capacity are but down to 5~20% and 1.1~4.4gkg；Pharmaceutical field capsule storage environmental demand be 24 DEG C,
Relative humidity and water capacity are 35~40% and 6.5~7.4gkg；Storing grain in food production and dry temperature
Down to 16 DEG C, relative humidity and water capacity require to be 40% and 4.5g/kg demand；The temperature of printing bookbinding process in production in light industry
Up to 32 DEG C of degree, but relative air humidity will but be controlled in 30% or so (water capacity 8.9g/kg).So generally speaking,
Required most of industrial production occasions are all the lower environment of humidity, indoor water capacity control usually all 10g/kg with
Under, and water capacity demand is also very universal in 5g/kg low moisture environments below.
The demand of industrial low moisture environments and strict requirements are proposed for air handling equipment to the control of indoor temperature.
The conventional means of humid control has three kinds of dehumidification by condensation, solution dehumidification and rotary wheel dehumidifying in industrial building at present.Wherein, use is cold
When the air-conditioning equipment of solidifying dehumidification mode provides low moisture environments for industrial building, the sink temperature used in air-conditioning equipment must be non-
It is often low, the dew-point temperature of air under low water capacity environment is can be only achieved hereinafter, to achieve the purpose that air dewetting.So cold at this time
The energy consumption of the relevant devices such as water dispenser group can be very big, to bring high operating cost.In addition, the Air Temperature after dehumidification by condensation
Degree is same very low, therefore also needs additional hot cell again, and to promote wind pushing temperature, to meet industrial demand, this is again
The energy consumption for resulting in air-conditioning system further increases.
For the excessive problem of dehumidification by condensation mode energy consumption, the solution dehumidification technology of on-mechanical dehumidification mode is used in recent years
It is widely used.In liquid desiccant air conditioning unit, air is in direct contact with dehumidification solution, the moisture in air
Solution can be dehumidified directly to absorb, and dilute after dehumidification solution can using the low level heat energies such as industrial waste heat and solar energy come
It is regenerated.The great advantage of this kind of air-conditioning system is that energy-saving effect is notable, and cryogenic temperature need not be very low, it is only necessary to be met aobvious
The processing requirement of thermic load, in addition solution dehumidification process be accompanied by the release of heat, therefore after air is dehumidified cooling
Temperature will not be especially low.Although liquid desiccant air conditioning unit is advantageous in energy-saving square mask, and it is low so to apply it to industry
Some problems can be encountered when the control of wet environment.For example, when the processing of air humidity load is excessive, air-supply water capacity demand is too low,
The solution dehumidifying air-conditioning system of single-stage is difficult to meet the requirements, it is necessary to which, using multistage form, this results in equipment occupation space mistake
Greatly, the excessively high problem of cost, and at this time used in dehumidification solution very high, the conventional dehumidification solution type of concentration requirement
It is difficult to reach requirement, unit corrosion caused by excessively high solution concentration is also difficult to solve with regeneration energy consumption problem.So individually
Solution dehumidification system be not be very suitable for depth dehumidifying occasion.
Rotary wheel dehumidifying is a kind of common technology suitable for depth dehumidification process, the use of Revolving wheel dehumidification apparatus is that industry is raw
It is a kind of feasible technological means that production, which provides low moisture environments,.And the release of heat is so usually associated with during rotary wheel dehumidifying, it is empty
Gas can bring larger Wen Sheng, excessively high wind pushing temperature that can not meet the needs of Environment Inside the Building temperature while being dehumidified.
It is to limit the most important factor of Revolving wheel dehumidification apparatus isolated operation that air parameter, which adjusts inflexible defect,.
It is suitable for most of industrial building low humidities in view of the above-mentioned problems, how to be built on the basis of existing technological means
The air-conditioning system of environment and temperature requirement, while meeting environmental protection and energy-efficient demand, it is that current air-conditioning equipment manufactures and designs field
One problem of required solution.
