As shown in Figure 1, the course of work of pre-dehumidifying vaporizing type air conditioner of the present invention is as follows:
Outdoor new wind is entered by air inlet 1 in the housing 7 of pre-dehumidifying vaporizing type air conditioner, in the first pouring liquid packing layer 102, directly contact with the LiCl aqueous solution that is sprayed 40% concentration of coming by the first pouring liquid shower nozzle 101, moisture in new wind is absorbed by the LiCl aqueous solution, and new wind is dried; Dry air continues to flow to the first packing layer 117, the water of sending here with the first water pump 115 there and spray through the first drenching sprayer 129 directly contacts, water is evaporated, sensible heat transfer feedwater is realized humidifying cooling by dry air, and the cold air after reducing temperature twice is sent to indoor from gas outlet 2.
In said process, the first heat that drenches the 102 moisture absorption process generations of liquid packing layer is delivered to the second packing layer 123 by heat pipe 126, there with indoor return air (or the cold air being entered by cold wind entrance 6 for subsequent use of the low temperature of being sent here by cold wind blower fan 120, be applicable to the situation of outside air temperature lower than indoor air temperature) directly contact with the water being sprayed by the second drenching sprayer 122, evaporation of water adds the double action of low temperature return air cooling, take away the heat that dehumidification process discharges, the new wind that air inlet 1 is flowed into carry out dry in, also reduced the temperature of new wind, realize dehumidifying and cooling.LiCl concentration of aqueous solution after moisture absorption reduces, and becomes weak solution, is transported to ultrafilter 106 by the first liquid pump 103, filtering after the pollutant of bringing in air, then flow into nanofiltration device 107.
Due to the crown_interception of nanofiltration device 107 to LiCl salt, the concentration of the trapped fluid of nanofiltration device 107 is elevated to 40%, after the first magnetic valve 127, is again sprayed by the first pouring liquid shower nozzle 101 as hygroscopic agent, and nanofiltration device 107 see through below the concentration step-down to 15% of liquid, sprayed to the second pouring liquid packing layer 105, (high temperature air is generally hot outdoor air to the high temperature air of sending here with air-heater 113 there, if indoor air temperature is higher than outside air temperature, high temperature air is herein return air in hot room) directly contact, because the steam dividing potential drop of high temperature air is much smaller than the surface vapor pressure power of LiCl thin liquid, moisture in LiCl thin liquid is blown away by high temperature air, the water yield evaporating in LiCl thin liquid equals the water yield that dehumidifying obtains from air in the first pouring liquid packing layer 102, LiCl solution after dehydration retrogradation, deposit to the second liquid bath 110, then carried and get back to the first liquid bath 104 by the second liquid pump 108, the holding back of nanofiltration device 107, second drenched evaporation in liquid packing layer 105 and anhydrates, adds the comprehensive function of the adjusting of magnetic valve 127,109, and what make that the first pouring liquid shower nozzle 101 sprays is that concentration is 40% LiCl dope all the time, has realized the regeneration of dehumidification liquid.
