Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
Embodiment one:
As shown in Figure 1, the Fresh air handling units of the present embodiment comprises a Fresh air handing passage and a return air treatment channel, and wherein, Fresh air handing channel arrangement is in the lower floor of return air treatment channel.
Fresh air handing passage comprise three grades of settings (for three grades, be not limited to three grades) solution moisture removing device D; Return air treatment channel comprise three grades of settings (for three grades, be not limited to three grades) direct evaporative cooler E, two-stage (for two-stage, being not limited to two-stage) solution regenerator R is set in the front of direct evaporative cooler E.Between each solution moisture removing device D and direct evaporative cooler E, one solution-water-to-water heat exchanger 1 is all set, a heat-exchange end of solution-water-to-water heat exchanger 1 connects to form solution circulation loop with the solution moisture removing device D being positioned at its side by a solution circulation pump 2, meanwhile, another heat-exchange end of solution-water-to-water heat exchanger 1 connects to form water-flow circuit with the direct evaporative cooler E being positioned at its opposite side by a water pump 3.Each solution regenerator R all connects to form solution circulation loop by a solution circulation pump 2 and one solution-water-to-water heat exchanger 4.Each solution moisture removing device D and each solution regenerator R is connected in series composition solution circulation loop, and in the solution circulation loop between solution moisture removing device D and solution regenerator R, arrange a solution-solution heat exchanger 5.
In the present embodiment, in summer, the heat-exchange end of solution-water-to-water heat exchanger 1 can be connected with cold water pipeline, to increase the dehumidifying effect of solution moisture removing device D; And time in the winter time, then the heat-exchange end of solution-water-to-water heat exchanger 1 can be connected with hot water line, thus solution moisture removing device D is made to possess humidification capability.No matter the heat-exchange end of solution-water-to-water heat exchanger 4 is summer or winter then, be connected with hot water line all the time.
In the present embodiment, solution moisture removing device D and solution regenerator R all adopts heat insulation-type.
The operation principle of the Fresh air handling units of the present embodiment is as follows:
As shown in Figure 1, new wind (pending air) flows through three grades of solution moisture removing device D successively, in solution moisture removing device D with from its top spray solution carry out distributary caloic exchange process, complete with the caloic exchange process of solution moisture removing device D at different levels after, new rheumatism degree meets processing demands, becomes the place that air-supply is sent to demand.
Utilize solution circulation pump 2, be sent in corresponding solution-water-to-water heat exchanger 1 by the solution major part flowed out bottom solution moisture removing device D, utilize cold/hot water to lower the temperature to solution/heat, strengthen the dehumidifying/humidifying ability of solution.The solution flowed through after solution-water-to-water heat exchanger 1 is sent to solution moisture removing device D top spray again, carries out caloic exchange with new wind.The solution that fraction flows out bottom solution moisture removing device D flow to the next solution moisture removing device D of series connection with it, and the fraction solution flowed out from the solution moisture removing device D of forefront is then finally sent to solution regenerator R.
Meanwhile, return air (indoor exhaust wind) flows through three grades of direct evaporative cooler E successively, and carries out distributary caloic exchange process with the cooling water under from its top spray, realizes the energy regenerating to return air.Afterwards, indoor exhaust wind continues two-stage solution regenerator R, and carries out distributary caloic exchange process with the solution under from its top spray, utilizes indoor exhaust wind to realize the regeneration to solution as regeneration air.Indoor exhaust wind becomes air draft and is discharged after being flowed out by solution regenerator R.In indoor exhaust wind evaporative cooling unit, the cooling water from three grades of direct evaporative cooler E top sprays, after completing caloic exchange process with return air, by flowing out bottom direct evaporative cooler E, and flows in corresponding solution-water-to-water heat exchanger 1.Heat up after cooling water and solution heat exchange, and flow out from solution-water-to-water heat exchanger 1, be sent to corresponding direct evaporative cooler E top spray by water pump 3 cooling water, complete the cyclic process of cooling water.
For the solution flowed out bottom solution regenerator R, major part is sent in corresponding solution-water-to-water heat exchanger 4, the heat-exchange end of solution-water-to-water heat exchanger 4 connects hot-water line line of reasoning, hot water etc. is utilized to heat solution, so that the caloic increased between solution and regeneration air exchanges driving force, improves regeneration effect.Be sent to solution regenerator R top spray again by the solution after heating, carry out caloic exchange with indoor exhaust wind.The solution that fraction flows out bottom solution regenerator R flow to series connection with it connect next solution regenerator R, and after mixing with the part solution flowed out from solution regenerator R together be sent to solution moisture removing device D.For the solution circulated between the solution regenerator R and solution moisture removing device D of solution dehumidification-regeneration cycle unit, utilize solution-solution heat exchanger 5 to carry out recuperation of heat, reduce the heat of this Fresh air handing flow process, refrigeration requirement, improve process efficiency.
Be presented above device operation principle when summer new wind being dehumidified, time in the winter time, utilize the direct evaporative cooler E between indoor exhaust wind and water, the energy regenerating to indoor exhaust wind can be realized; By changing the modes such as hot water line, solution-water-to-water heat exchanger 2 can be changed into solution-hot water heat exchanger, the solution after solution moisture removing device D can utilize heating comes new wind warming and humidifying, and whole treating apparatus can realize the humidification processing capacity of new wind.
