The specific embodiment
Fig. 1 illustrates schematic diagram, and it illustrates the structure that is used for the dehumidifying of air stream according to of the present invention on the one hand, and also illustrates the method that is used for the dehumidifying of air stream according to of the present invention on the other hand.Device comprises the air duct with inlet 1 and outlet 2, supplies with air to be dehumidified by described inlet, by the air of described outlet discharge through dehumidifying.Circulation of air is crossed arrow 3 and is illustrated.Air duct is divided into two districts 4 and 5, perhaps as shown, is divided into four districts 4,5,6A and 6B, and wherein these districts directly adjoin each other, and perhaps separate slightly mutually.First district 4 is used to cool off the air stream of supply, and wherein the air stream in the end in first district 4 is cooled to dew-point temperature or a little more than the temperature of dew-point temperature.Dew-point temperature is humid air residing temperature when steam-laden, condensation water outlet under the situation that continues to descend in temperature.Therefore, dew-point temperature is that humid air is 100% o'clock residing temperature at relative air humidity phi.Therefore in first district 4, air mainly is cooled, and does not have the condensation water outlet.Possible is go out some water in the condensation of the end in first district 4, and this not to hinder one's work.This for example is following situation, when temperature is lower than dew-point temperature, because temperature must be conditioned, so nature can take place.Second district 5 is used to make air stream cooling and dehumidifying, that is to say, isolates moisture from air stream, and with the form condensation of water.Water enters rhone.Therefore, the temperature in second district 5 must all be lower than the dew-point temperature of the part of air stream throughout.The 3rd district 6A and the 4th district 6B are optionally, and are used for will being heated to the temperature of hope through the cold air stream of dehumidifying with effective and efficient manner.Whether need this two districts, relevant with the working method of air-conditioner.
In addition, device is equipped with at least one sensor, so that make described device running according to the method according to this invention of explanation below.At least one sensor is used to measure the temperature and/or the relative humidity of air stream.
The method that is used for the dehumidifying of air stream according to the present invention correspondingly comprises step:
A) make air stream flow through first district 4, in described first district, air stream be cooled to make its temperature reach to be equivalent in the end in this district 4 dew-point temperature or a little more than the value of dew-point temperature;
B) make air stream flow through second district 5, in described second district, air stream is cooled to dew-point temperature, makes the condensation water outlet; And
C) alternatively, make air stream flow through the 3rd district 6A, in described the 3rd district, air stream is cooled to dew-point temperature, makes the condensation water outlet, and makes air stream and then flow through the 4th district 6B, in described the 4th district, air stream is by the heat heating in the 3rd district 6A inner accumulated.At this, note following aspect:
The dew-point temperature of-air is relevant with different factors, and is especially relevant with the pressure of the water content of the temperature of air, air and air.The relative air humidity phi that represents with % is illustrated in the ratio of airborne present water vapour content and the water vapour content of maximum possible under identical temperature;
-dew-point temperature in district 5 and 6A descends along described these districts, because condensation water outlet in these districts this means that the water content of air stream reduces continuously, and also minimizing continuously of therefore relative air humidity phi;
Dew-point temperature on the optional position of-air stream in district 5 and 6A for example can followingly be determined, promptly by temperature and relative humidity phi by means of sensor measurement air stream, and measures relevant dew-point temperature then.Dew-point temperature T P1For example can measure by calculating by means of following formula:
T p 1 = 241.2 * ln ( phi 100 ) + 4222.03716 * T 25 241.2 + T 17.5043 - ln ( phi 100 ) - 17.5043 * T 241.2 + T - - - ( 1 )
Wherein temperature T and T P1Unit be degree centigrade that and relative air humidity phi represents with percentage.But, dew-point temperature T P1Also can measure by means of mollier diagram.
Mollier diagram also be applicable to the dehumidification process of expression air stream how to derive thus district 4 and 5 or 4,5 and 6A in regulate temperature.Fig. 2 illustrates mollier diagram.This figure contains gang's curve, and described curve illustrates dew-point temperature T P1The function as the water content X of air and temperature T represent the curve of the different value of relative air humidity phi.Example by means of temperature of selecting at random by Fig. 3 with air stream and relative air humidity elaborates dehumidification process below, and described Fig. 3 illustrates the part of amplification of the mollier diagram of Fig. 2.The process that is used for the dehumidifying of air stream illustrates by four interconnective arrows.One of district 4,5,6A and the 6B of each of four arrows and the device that is used for air stream dehumidifying is associated.When air flow to into first district 4, promptly at inlet 1, air stream had temperature T=30 ℃ and relative air humidity phi=50% in this example.When district 6B discharges, promptly in the outlet 2 of the device that is being used for the dehumidifying of air stream, air stream should have in this example T=22 ℃ with relative air humidity phi=30%.In first district 4, air stream just is cooled, and does not have the condensation water outlet.Therefore, vertical extension of first arrow and sensing are down.Air stream must be cooled to temperature T in first district 4 1, described temperature roughly is equivalent to the dew-point temperature T of air stream P1, T in example P1=18.5 ℃.If in first district 4, forbid the condensation water outlet, so temperature T 1Must be higher than dew-point temperature T P1But, if in first district 4, especially in the zone of the end in first district 4, can the condensation water outlet, the temperature T that flows of the air in the zone of the end in first district 4 so 1Also can reach and be lower than dew-point temperature T P1Value.In second district 5, air stream is dehumidified continuously.Because in this air flow losses moisture, so dew-point temperature reduce continuously along second district 5, as in mollier diagram, finding out significantly.In the 3rd district 6A, air stream is dehumidified equally continuously, so dew-point temperature reduces equally continuously along the 3rd district 6A.In described example, the air stream in the end of the 3rd district 6A must reach temperature T 2=3.5 ℃.In the 4th district 6B, air stream for example is heated to the temperature of 22 ℃ hope, so air stream also reaches the relative air humidity phi=30% of hope there.
Two districts 6A and 6B are the mutual coupling connection mutually, makes gather and heat to be transported drainage area 6B in district 6A, so that air stream is heated to the temperature of hope.Require to adjust or regulate according to this in the dew-point temperature when second district 5 carries out the transition to the 3rd district 6A.
A primary aspect of the invention relates to the cooling and the dehumidifying of air stream, wherein cool off in first district 4 and carry out, also not condensation water outlet from air stream in described first district, wherein the relative air humidity when discharging from first district 4 is almost 100% in the ideal case, and wherein just dehumidifies in second district 5 subsequently.This distributes the material and the surface texture of the wall portion in qualification first district 4 that allows the optimization air duct, to be used to optimize the heat transmission of not being with condensation, and the material and the surface texture that should distribute the wall portion in qualification second district 5 that allows the optimization air duct, have the heat transmission that condensation formation or water droplet form to be used to optimize, and be used for discharging apace the water of condensation.Best is, forms individual layer water in the wall portion in second district 5, because so extremely thin layer one side causes the quick discharge of water, and to provide on the other hand be low thermal resistance.The possible embodiment of the wall portion in second district 5 is, wall portion is with having material coating hydrophobic along the part of gravity direction variation from the top down and hydrophilic interaction, wherein hydrophobic part accounts for major part in upper area, and hydrophilic segment accounts for major part in lower area.
When air stream left second district 5, air stream was cold and relatively dry.Now, air stream for example can directly be supplied with the space of pending air conditioning, perhaps mixes with fresh air and supplies with the space, perhaps mixes also with the waste gas of discharging from the space and supplies with the space once more, perhaps is heated and as treated air-supply supply space.Another aspect of the present invention relates to a kind of device, in described device, air duct is divided at least four districts 4,5,6A and 6B, wherein the temperature in the 3rd district 6A may be adjusted to, make the air stream in the 3rd district 6A discharge the moisture of water outlet form, and wherein will flow at the air that the used heat of the 3rd district 6A inner accumulated is supplied with in the 4th district 6B.This advantageously carries out by means of at least one Peltier's element, and described Peltier's element is used for making its cold side on the one hand that the wall portion of the 3rd district 6A is cooled to the temperature of needs, and its warm side wall portion of heating the 4th district 6B on the other hand.
