Description
Technical field
The present invention relates to a kind of damping air-conditioner sets, in particular to a kind of solution tune of dehumidifying or damping is carried out using solution
The structure of wet Fresh air handling units, the invention belongs to field of heating ventilation air conditioning.
Background technique
In Heating,Ventilating and Air Conditioning industry and engineering in use, currently used dehumanization method and its system can substantially be divided into cooling
Dehumidifying, chemical de-moisture, representing is respectively freeze drying, solution dehumidification.The two is a kind of most widely used mode, solution
The main technical solution of dehumidification mode be using with hygroscopic nature salting liquid as working media, directly contacted with fresh air into
Row heat and mass realizes the dehumidification treatments process to fresh air.Since it is lower with energy consumption, dehumidifying effect relatively freezes solution dehumidification
It dehumidifies the advantages that strong, earn widespread respect in recent years and is widely applied.Existing freeze drying and solution dehumidification are also deposited
In various deficiencies, the disadvantage of freeze drying is that the air dew point after dehumidifying is higher；And the major defect of solution dehumidification is to need
It is larger to regenerate heat source, unit volume；Freeze drying and solution dehumidification are combined, are especially one in terms of Fresh air handing
The selection of the two advantage is taken into account, i.e., pre-dehumidified is carried out to fresh air using freeze drying, recycles liquid dehumidifying to the new of pre-dehumidified
Wind is further dehumidified.
Although having there are some examples for being combined the two at present, the advantages of both how making full use of, gram
Its disadvantage respectively is taken, is still worth being explored；This includes how to increase dehumidifying while reducing temperature required for solution regenerates
Ability does not influence the regeneration effect of solution, how to pass through while how reducing the condensation temperature of refrigeration system using condensed water
The adjusting of solution concentration effectively to control humidity etc..
When summer, outdoor temperature is generally greater than room temperature, and when winter, outdoor temperature is generally below room temperature, for section
Can be environmentally friendly, it needs to carry out energy regenerating to air draft；
Patent ZL200610012259.3 discloses a kind of heat pump driven multi-stage solution dehumidifying and regeneration Fresh air handling units, should
Solution dehumidifying fresh air handling group uses the cooling capacity of solution-type total heat recovery device recycling indoor exhaust wind, due to solution-type total heat recovery device
Limited for the cooling effect of fresh air, i.e., heat recovery efficiency is lower, needs using multi-stage solution formula total heat recovery device.
Patent 201010175863.4 discloses a kind of utilization transpiration-cooled solution dehumidifying fresh air handling group of indoor exhaust wind, should
Solution dehumidifying fresh air handling group evaporates the cooling cooling capacity generated using indoor exhaust wind and fresh air is pre-chilled, similarly, since evaporation is cold
But efficiency is lower, to realize the purpose to pre-cooling of fresh air, needs to be arranged multi-stage solution dehumidifying, evaporation cooling.
As shown in Figure 1, being exactly the solution dehumidifier using above-mentioned technology, it is seen then that unit size is big, and structure is complicated, cannot
Realize fragmented transport, on-site assembly, it is the operation of unit, difficult to install.
