Abstract
The invention discloses a kind of air dehumidification and cooling device with heat reclaiming ability. The invention comprises air dehumidification agent which is made up of dehumidification model and board heat exchanger, indirect evaporating cooler and air-water heat exchanger. The dried air after dehumidified by the dehumidification device, and enters the air-water heat exchanger to be cooled. The water out of the air-water heat exchanger is returned back to the indirect evaporating cooler.
Description
Technical background
The present invention relates to field of air conditioning, relate in particular to the air dewetting cooler.
Background technology
The air dewetting chiller applications is used to remove the steam that air contains in field of air conditioning.Present air dehumidifier has distributary from the contact form of air and solution, and adverse current or following current are also arranged.Typical situation comprises the liquid dehumidifier of U.S. Kathabar company and the dehumidifier of Israel Drykor company, and the former is an adverse current, and the latter is a distributary.From the flow process dehumidifier single-stage is arranged,, the dehumidifier of classification is arranged also, described two kinds of multistage method for dehumidifying liquid as patent documentation CN01141371.9 and CN01138603.7 as top two kinds of listed dehumidifiers.But all these prior aries have only been mentioned water capacity how to handle air, do not relate to the problem of control air themperature.In dehumidification process,,, need further handle the requirement that just can reach air-supply to wind through dehumidifier usually at 40 ℃ even higher because the restriction of cooling condition makes that the air themperature of process dehumidifying is higher.And common way is that a cover air-conditioning system is joined a used for refrigerator in the cold water that produces lower temperature again except dehumidifier now, goes the cooling air-supply with cold water, perhaps sends into indoor by the thermic load in the fan coil process chamber.The shortcoming of this system is that investment is big, operation energy consumption is big.
Summary of the invention
At the problem and shortage that prior art exists, the purpose of this invention is to provide a kind ofly be easy to make, the air dewetting cooling device of with low cost, the simple band of control recuperation of heat.
In order to realize the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of air dewetting cooling device with recuperation of heat comprises the multistage air dehumidifier of forming, indirect evaporation cooler and air-water-to-water heat exchanger by dehumidification module and plate type heat exchanger.Its design feature is, by the dry air of the heat after the dehumidifying of multi-staged air dehumidifier, is cooled through air-water-to-water heat exchanger through the cold water that is lower than indoor return air wet-bulb temperature with the indirect evaporation cooler preparation.The water that comes out from air-water-to-water heat exchanger inserts in the dehumidifying outlet side plate type heat exchanger the multistage dehumidifier by pipeline and returns indirect evaporation cooler behind the cooling and dehumidifying solution.Indoor return air becomes damp and hot air and discharges outdoor through behind the indirect evaporation cooler.
Above-mentioned multistage air dehumidifier is the level Four air dehumidifier.
The present invention adopts indoor return air, through an indirect evaporation cooler, makes the cold water of lower temperature, can cool off the higher air of handling through multistage dehumidifier of temperature with this cold water, can also be used for the cooling and dehumidifying process in multistage dehumidifier.Use this flow process, avoided the use refrigerator, and apparatus for cooling by indirect evaporation is made easily, cost is low, and control is simple, makes the initial cost of system significantly reduce.And use air draft to produce cold water, effectively reclaimed indoor cold through apparatus for cooling by indirect evaporation.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
Specify embodiments of the present invention below in conjunction with accompanying drawing.
The specific embodiment
Referring to Fig. 1, a kind of air dewetting cooling device with recuperation of heat comprises level Four air dehumidifier, indirect evaporation cooler 11 and the air-water-to-water heat exchanger 10 be made up of dehumidification module 4 and plate type heat exchanger 3.Plate type heat exchanger 3 has cooling water inlet 1 and coolant outlet 2.Air 5 contacts with denseer water salting liquid 6 in dehumidification module 4, because the water capacity of air is higher, the steam partial pressure of air is higher than the steam partial pressure of solution, and solution absorbs airborne steam, make the water capacity of air reduce, solution has been inhaled airborne water vapor concentration and has been reduced.This dehumidification process is divided into level Four, and air and solution are counter-flow arrangement, and every water capacity through main air is lowered some outlet of one-level dehumidifier to the last.Therefore because cooling is normally made by cooling tower, the wet-bulb temperature of cooling water temperature and outdoor air is suitable, and the temperature of the processing air that comes out from afterbody generally is not less than 26 ℃, does not reach the requirement of indoor air-supply, needs further cool off.Air 15 after the cold water 12 of the approaching indoor return air dew-point temperature of described indirect evaporation cooler 11 preparations is dehumidified by the level Four air dehumidifier through 10 coolings of air-water-to-water heat exchanger can reach about 23 ℃ through air-supply after the supercooling, satisfies the requirement of air-supply.Owing to the temperature of the water 14 that comes out from air-water-to-water heat exchanger 10 is lower, be usually less than the temperature of cooling water 1, therefore can utilize cold water 14 to go the cooling and dehumidifying process, make the cold of return air be fully utilized like this.The water 14 that comes out from air-water-to-water heat exchanger 10 inserts by pipeline in the plate type heat exchanger 3 of dehumidifying outlet side the level Four air dehumidifier and returns indirect evaporation cooler 11 behind the refrigerated brine solution.Indoor return air 8 becomes damp and hot air 9 and discharges outdoor through indirect evaporation cooler 11.
