Fig. 1, the present invention primary structure schematic diagram.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Referring to Fig. 1, the small-sized household formula solution humidifying Fresh air handling units of external low-temperature receiver of the invention, the unit mainly contains auxiliary Help low-temperature receiver, solution module, refrigeration system.The auxiliary cold source needs external high temperature cold water;It is molten that the solution module includes regeneration Liquid module, dehumidification solution module, matched solution pump and pipeline;The refrigeration system includes compressor, evaporator, condensation Device, expansion valve and matched pipeline.The characteristics of device is maximum is to take full advantage of condensation heat to carry out solution regeneration, is both solved Determine condenser heat dissipation problem, the problem that weak solution regenerates after solution dehumidification is solved again, the cold in return air is make use of, without External auxiliary radiating device, reduces device structure size and manufacturing cost.
Described unit, the solution module is main by actified solution module, dehumidification solution module and matched molten Liquid pump and pipeline composition;Its operation principle is:1. fresh air first passes through the high temperature desuperheating coil pretreatment of external low-temperature receiver, disposes absolutely Most of sensible heat load;Enter back into evaporator and carry out frozen cooling dehumidifying, the humidity load and fraction for disposing the overwhelming majority are aobvious Thermic load;Solution dehumidification module is entered back into, fresh air is dehumidified by further constant enthalpy, reach suitable ventilation state point.2. it is indoor to return First condensed device is heated wind, and heated high temperature air draft enters back into solution regeneration module, improves the regeneration efficiency of solution, Moisture in regeneration module takes outdoor out of, completes the regeneration of solution.The surface cooler and evaporator of precooling, which are anticipated, easily to be gone The humidity load removed, solution is responsible for a part of humidity load of the last more difficult dehumidifying of processing, and set structure chi is substantially reduced on the whole It is very little so that unit can be highly suitable to be applied for small-sized storied office building, hotel apartment, villa and ordinary residence etc. small with indoor hoisting Space buildings project.
As shown in figure 1, the unit, the schematic diagram that it runs is as shown in Figure 1:Its critical piece includes solution module, system The surface cooler of cooling system and external auxiliary cold source.The solution module include actified solution module 9, dehumidification solution module 8 and Matched solution pump 5 and pipeline;The refrigeration system includes compressor 2, condenser 3, evaporator 4, expansion valve 6 and therewith Supporting pipeline;The surface cooler of the external low-temperature receiver is to need the surface cooler 7 and matched pipeline of external auxiliary cold source.
Outdoor fresh air is by surface cooler 7, by the pre-dehumidified that cools in advance, temperature reduction, and humidity is reduced, by evaporating surface cooler 4, By further by straight swollen cooling and dehumidifying, afterwards by dehumidification solution module 8, constant enthalpy dehumidifying reaches and meets indoor air-supply requirement State point.
Indoor return air passes through condensation surface cooler 3, absorption condensation heat, temperature rise, by actified solution module 9, to solution Concentrating regenerative is carried out, discharge is outdoor.
The solution module is main by dehumidification solution module 8, actified solution module 9 and matched solution pump 5 and pipe Road is constituted;The fresh air of outdoor introduction first passes around the processing of the surface cooler 7 pre- cool-down dehumidification, then enters one by the evaporator 4 Dehumidifying and cooling is walked, the dehumidification solution module 8 is eventually passed, is dehumidified by constant enthalpy, the state point for meeting indoor air-supply requirement is reached. Indoor return air first passes around the condenser 3, the condensation heat that absorptive condenser 3 is discharged, as high temperature return air, then by described Actified solution module 9, the weak solution after being dehumidified to dehumidification solution module 8 carries out concentrating regenerative.
The refrigeration system is mainly made up of compressor 2, evaporator 4, expansion valve 6 and matched pipeline;Pass through pressure The cold-producing medium stream of the later HTHP of contracting machine 2 enters expansion valve 6, then to condenser 3 after being radiated by condenser 3 Evaporator 4 is flow to, the refrigerant of low-temp low-pressure expands sweat cooling in evaporator 4, and the refrigerant after heat absorption finally flows into pressure Contracting machine, is circulated according to this.The entrance phase that the outlet of refrigerant circulating passage in the evaporator 4 passes through pipeline 22 and compressor 2 Even, the outlet of compressor 2 is connected by pipeline 23 with the entrance of the refrigerant circulating passage of the condenser 3, the condenser 3 The outlet of refrigerant circulating passage be connected by pipeline 24 with the entrance of the expansion valve 6, the outlet of expansion valve 6 passes through pipeline 21 are connected with the entrance of the refrigerant circulating passage of the evaporator 4.
The auxiliary cold source is mainly made up of surface cooler coil pipe 7 and matched pipeline.High temperature cold water accesses the table In cooler coil pipe 7, cool-down dehumidification is carried out to air.
The actified solution module and dehumidification solution module utilize the water vapor partial pressure differential in the air on salting liquid surface Hot and humid area is carried out, the dehumidification treatments to air are realized using the moisture-absorption characteristics of various concentrations solution;The actified solution module Consistent with dehumidification solution modular structure, internal filler is formed by non-woven fabrics and ABS material high temperature hot pressing, using corrugated shape It is superimposed, it is ensured that solution is not taken out of by wind;Housing uses ABS material, mould integrated molding;The salting liquid of inner loop Using lithium bromide, calcium chloride or lithium chloride.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and Modification, these improvement and modification also should be regarded as protection scope of the present invention.
