Description
Technical field
The invention belongs to air-conditioning unit field, be specifically related to a kind ofly based on absorption refrigeration, can realize and absorb the independent humiture-controlled air conditioner group that the solidifying heat extraction of hot and cold is recycled.
Background technology
Absorption Refrigerator can make full use of industrial exhaust heat, and its water is as cold-producing medium, there will not be destruction and greenhouse effects to ozone layer.But due to the technical characterstic of Absorption Refrigerator " with heat raw food ", its coefficient of refrigerating performance is far below voltage compression type refrigerating, under identical cooling load, the heat extraction of Absorption Refrigerator is much larger than the condensation heat release of electric compression refrigerating machine, discharge in vain a large amount of heat energy by cooling tower every year, consumed a large amount of cooling water resources.
Humiture autonomous control system, by means of solution dehumidification, the temperature of chilled water can significantly rise to 18～21 DEG C by 7 DEG C of original left and right, has greatly promoted the refrigeration performance of refrigeration unit.But the solution regenerator in system need to consume heat energy, this heat energy provides very important to whole system energy consumption by which kind of mode, current existing solution is all to adopt solar energy as thermal source, and solar energy is the unsettled energy, need auxiliary thermal source, its energy consumption is likely offset the energy consumption that solution dehumidification mode is saved.
Summary of the invention
The object of the present invention is to provide a kind of independent humiture-controlled air conditioner group based on absorption refrigeration, this unit can effectively utilize the heat extraction of Absorption Refrigerator absorber and condenser, and the weak solution after solution dehumidification is concentrated to regeneration.Provide in absorption refrigeration on the basis of the cooling air-supply of chilled water, can effectively realize the humiture of indoor air-supply and independently control, more traditional freeze drying simultaneously can increase substantially the refrigeration performance of Absorption Refrigerator and the air quality of air-supply.
The object of the invention is to realize by the following technical solutions:
On the basis of original absorption refrigeration unit, increase air-supply humiture and independently control cell, in cell, be provided with successively elementary surface cooler, internally cooled dehumidifier and secondary table cooler, respectively air-supply is carried out to warm and humid independent control.Weak solution after solution dehumidification effectively utilizes absorber and condenser heat extraction to concentrate regeneration.
As one embodiment of the present invention, Absorption Refrigerator chilled water that evaporimeter supplies for described surface cooler, cools to indoor air-supply, independently controls with the temperature that realizes air-supply.
As one embodiment of the present invention, internally cooled dehumidifier of the present invention, directly sprays in out the dehumidification solution after concentrated regeneration on the chilled water coil pipe of secondary table cooler, and indoor air-supply is carried out to dehumidification treatments, independently controls with the humidity that realizes air-supply.
As one embodiment of the present invention, the weak solution of dehumidifying after dust suction by filter filtration, purification after, the coil pipe of flowing through in absorber heats, then directly spray on the heat exchange coil of high pressure refrigerant vapour, then under the airflow function of dehumidifying blower fan, exchange the concentrated regeneration that realizes dehumidification solution by caloic.It directly utilizes the heat extraction of Absorption Refrigerator to carry out the concentrated regeneration of dehumidification solution, and the regeneration of waste liquor thermal source that does not need volume to add, and has also saved the cooling water temperature device such as cooling tower of traditional absorption refrigeration unit.
Compared with conventional absorption refrigeration unit, the present invention has the following advantages: can effectively utilize the heat extraction of absorption refrigeration unit, realize the concentrated regeneration of dehumidification solution, save the cooling water temperature devices such as cooling tower, save a large amount of cooling water resources; Adopt solution dehumidification, can increase substantially the coefficient of refrigerating performance of absorption refrigeration unit, be of value to and improve wind pushing air quality; The humiture that can realize based on absorption refrigeration is independently controlled, and whole air-conditioning unit structure is simple, and operation is controlled convenient.

Detailed description of the invention
Below in conjunction with specific embodiment, the specific embodiment of the present invention is described.
As shown in Figure of description, weak solution after dehumidifying is first through the first solution strainer 18a, then with after dehumidifying concentrated solution heat exchange directly enter the absorber 2 of Absorption Refrigerator, and absorb the absorption heat release of low pressure refrigerant vapour, then enter solution regenerator 4, absorb high pressure cryogen condensation heat, under the effect of dehumidifying air-introduced machine 16 air-flows, complete concentrated regenerative process.The concentrated solution of regeneration, after the second solution strainer 18b filters, is stored in concentrated solution case 19, and concentrated solution case plays storage concentrated solution, the effect of coupling Absorption Refrigerator and the hot humidity load of air-treatment cell.
First indoor air-supply passes through elementary surface cooler 11 through row primary temperature reducing, then in internally cooled dehumidifier 14, dedusting dehumidifies under the spray of dehumidification solution, chilled water in internally cooled dehumidifier 14 absorbs air-supply dehumidifying heat release, to reduce concentrated solution surface vapor partial pressure power, increase air-supply effect on moisture extraction, the air-supply after dehumidifying continues to cool by humidity such as secondary table cooler 11b carry out.In air-supply dehumidification process, the mixed liquor that dehumidification solution is weak solution and concentrated solution is sprayed in institute, sprays dehumidification solution amount to increase, and strengthens whole air-supply effect on moisture extraction.
The chilled water of 3 confessions of Absorption Refrigerator evaporimeter supplies water and passes through successively secondary table cooler 11b, internally cooled dehumidifier 14, elementary surface cooler 11a.In air-treatment cell, whole air-supply processing procedure, air-supply all the time with chilled water countercurrent flow, strengthened the effect that cools of air-supply.
