Description
本發明,是關於除濕機。 The present invention relates to a dehumidifier.
在除濕機中,有一種吸入空氣(處理空氣),並使之通過除濕機內的除濕轉輪(rotor)進行除濕然後予以排氣之種類者。吸濕後的除濕轉輪,是藉由使其水分釋放於以加熱器加熱後的高溫再生空氣中,而可以連續性地對處理空氣進行除濕。因此,在此種除濕機內,係設有使:作為除濕對象的處理空氣、以及用以將除濕轉輪再生(乾燥)之再生空氣,此2種空氣流動的路徑。 In the dehumidifier, there is a type in which air (treatment air) is taken in and dehumidified by a dehumidifier in the dehumidifier and then exhausted. The moisture-removing dehumidification wheel is capable of continuously dehumidifying the process air by releasing moisture into the high-temperature regeneration air heated by the heater. Therefore, in such a dehumidifier, there are provided a path in which the two types of air flow are the process air for dehumidification and the regeneration air for regenerating (drying) the dehumidification wheel.
在專利文獻1所揭示的除濕機中,是在處理空氣與再生空氣之間進行熱交換。再生空氣,是被加熱器加熱後,將除濕轉輪的水分予以回收而成為高溫高濕。該高溫高濕的再生空氣,在第1熱交換器中,與通過除濕轉輪之前的處理空氣進行熱交換受到冷卻而冷凝。冷凝後之再生空氣的水分成為冷凝水而被回收。被回收水分後之低溫的再生空氣,在第2熱交換器中與通過除濕轉輪之後的 高溫處理空氣進行熱交換而被加熱,然後再藉由加熱器加熱之後,再次回到除濕轉輪。 In the dehumidifier disclosed in Patent Document 1, heat exchange is performed between the process air and the regeneration air. The regenerative air is heated by the heater, and the moisture of the dehumidification runner is recovered to become high temperature and high humidity. The high-temperature, high-humidity regeneration air is cooled and condensed by heat exchange with the process air before passing through the dehumidification rotor in the first heat exchanger. The moisture of the condensed regeneration air is recovered as condensed water. The low-temperature regeneration air after the water is recovered, in the second heat exchanger and after passing through the dehumidification runner The high temperature process air is heated by heat exchange and then heated by the heater to return to the dehumidification wheel.
如此地,在專利文獻1的除濕機中,是在兩個熱交換器中進行再生空氣的冷卻及加熱。冷卻側的第1熱交換器,是作為冷凝器的功能,從再生空氣冷凝出冷凝水來將水分回收。在加熱側的第2熱交換器,是在加熱器加熱之前,藉由預先加熱再生空氣來節省加熱器的電力。 As described above, in the dehumidifier of Patent Document 1, cooling and heating of the regeneration air are performed in the two heat exchangers. The first heat exchanger on the cooling side functions as a condenser, and condenses water from the regeneration air to recover the water. In the second heat exchanger on the heating side, the electric power of the heater is saved by heating the regeneration air in advance before the heater is heated.
但是,在專利文獻1的除濕機中,對於使用兩個熱交換器如何來使再生空氣冷凝的效率提昇,以提高處理空氣的除濕效率此點並無特別的考量。 However, in the dehumidifier of Patent Document 1, there is no particular consideration as to how the efficiency of condensing the reconditioning air is improved by using two heat exchangers to improve the dehumidification efficiency of the process air.
[專利文獻1]日本特許第3857809號公報 [Patent Document 1] Japanese Patent No. 3857809
本發明之課題,是在於藉由提升再生空氣的冷凝效率,來提高除濕機之處理空氣的除濕效率。 An object of the present invention is to improve the dehumidification efficiency of the process air of the dehumidifier by increasing the condensation efficiency of the regeneration air.
本發明的第1態樣,是提供一種除濕機,其具備:處理空氣路徑,係具有吸氣口和排氣口、及第1風 扇,係從上述吸氣口吸取上述處理空氣路徑內的處理空氣並從上述排氣口進行排氣、及除濕轉輪,係從上述處理空氣進行吸濕、及再生空氣路徑,係通過上述除濕轉輪的一部分,並由閉路徑所成、及第2風扇,係使上述再生空氣路徑內的再生空氣循環、及加熱器,係在上述再生空氣路徑內相對於上述再生空氣的循環方向是配置在就要到達上述除濕轉輪的跟前,用以加熱上述再生空氣、及第1熱交換器,是藉由通過上述處理空氣路徑內的上述除濕轉輪之前的上述處理空氣,與通過上述再生空氣路徑內的上述加熱器之前的上述再生空氣進行熱交換,來將上述再生空氣冷卻、以及第2熱交換器,是藉由通過上述處理空氣路徑內的上述除濕轉輪之後的上述處理空氣,與通過上述再生空氣路徑內的上述除濕轉輪之後且通過上述第1熱交換器之前的上述再生空氣進行熱交換,來將上述再生空氣冷卻。 According to a first aspect of the present invention, there is provided a dehumidifier comprising: a process air path having an intake port and an exhaust port, and a first wind The fan sucks the processing air in the processing air path from the air inlet, exhausts the air from the exhaust port, and dehumidifies the wheel, and absorbs moisture from the processing air and regenerates the air path through the dehumidification A part of the runner is formed by a closed path, and the second fan is configured to circulate the regeneration air in the regeneration air path and the heater in the circulation direction of the regeneration air in the regeneration air path. The heating air and the first heat exchanger are heated to pass through the process air before the dehumidification rotor in the air path and to pass the regeneration air before reaching the dehumidification wheel. The regeneration air before the heater in the path exchanges heat to cool the regeneration air, and the second heat exchanger is processed by the processing air after passing through the dehumidification rotor in the processing air path. Passing through the above-described dehumidification rotor in the regeneration air path and after the regeneration air before passing through the first heat exchanger Heat exchange to cool the above regeneration air.
依據該除濕機,於第1熱交換器及第2熱交換器之雙方,由於皆是將再生空氣冷卻,故冷凝水的回收量增大,而可以提昇再生空氣的冷凝效率。因此,可以從除濕轉輪回收較多的水分,而可以提昇處除濕轉輪的再生效率(乾燥效率)。由於如此,可以從通過除濕轉輪的處理空氣吸取更多的濕氣,而可以提昇處理空氣的除濕效率。在此,所謂處理空氣是作為除濕之對象的室內空氣,所謂再生空氣是在除濕機內循環用以使除濕轉輪再生的空氣。 According to the dehumidifier, since both the first heat exchanger and the second heat exchanger cool the regeneration air, the amount of condensed water recovered is increased, and the condensation efficiency of the regeneration air can be improved. Therefore, more moisture can be recovered from the dehumidification runner, and the regeneration efficiency (drying efficiency) of the dehumidification runner can be improved. As a result, more moisture can be drawn from the process air passing through the dehumidification wheel, and the dehumidification efficiency of the process air can be improved. Here, the process air is indoor air to be dehumidified, and the so-called regeneration air is air that circulates in the dehumidifier to regenerate the dehumidification wheel.
上述除濕機,其中上述處理空氣及上述再生空氣,相對於上述除濕轉輪的厚度方向,是從同方向進入上述除濕轉輪為佳。 In the above dehumidifier, it is preferable that the processing air and the regeneration air enter the dehumidification rotor from the same direction with respect to the thickness direction of the dehumidification rotor.
依據此除濕機,由於處理空氣與再生空氣從除濕轉輪的同一面進入,所以可以效率良好地進行除濕轉輪的吸濕及再生(乾燥),而可以提昇除濕效率。於除濕轉輪中,在處理空氣進入的面(進入面)與脫離的面(脫離面),其水分的含有量是不同的。具體上,進入面相對於脫離面其水分含有量較多。這是因為處理空氣在從進入面朝向脫離面地通過除濕轉輪時,會被慢慢地吸濕之故。因此,藉由設成使再生空氣從水分含有量較多的進入面進入之構成,可以回收更多除濕轉輪的水分,而可以提昇除濕轉輪的再生效率。 According to this dehumidifier, since the process air and the regeneration air enter from the same side of the dehumidification rotor, the moisture absorption and regeneration (drying) of the dehumidification wheel can be efficiently performed, and the dehumidification efficiency can be improved. In the dehumidification rotor, the moisture content of the surface (entry surface) and the detachment surface (release surface) where the treatment air enters is different. Specifically, the entry surface has a large amount of water content with respect to the release surface. This is because the process air is slowly absorbed when passing through the dehumidification rotor from the entry surface toward the release surface. Therefore, by setting the reconditioning air to enter from the inlet surface having a large water content, it is possible to recover more moisture of the dehumidification rotor, and the regeneration efficiency of the dehumidification rotor can be improved.
上述第1熱交換器及上述第2熱交換器,皆是使上述再生空氣冷凝的冷凝器為佳。 It is preferable that the first heat exchanger and the second heat exchanger are condensers that condense the regeneration air.
依據此除濕機,由於在第2熱交換器中預先進行再生空氣的冷凝,所以可以在第1熱交換器的冷卻過程全程中進行冷凝。因此,可以更加提昇再生空氣的冷凝效率,而可以提昇處理空氣的除濕效率。 According to this dehumidifier, since the condensation of the regeneration air is performed in advance in the second heat exchanger, condensation can be performed throughout the cooling process of the first heat exchanger. Therefore, the condensation efficiency of the regeneration air can be further improved, and the dehumidification efficiency of the treatment air can be improved.
根據本發明,在第1熱交換器及第2熱交換器之雙方,由於皆是將再生空氣冷卻,故使再生空氣的冷凝效率提昇而可以提昇處理空氣的除濕效率。 According to the present invention, since both the first heat exchanger and the second heat exchanger cool the regeneration air, the condensation efficiency of the regeneration air is improved, and the dehumidification efficiency of the treatment air can be improved.

以下,參照添附的圖面來說明本發明的實施形態。 Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.
第1圖,是本發明之實施形態的除濕機2的系統圖。參照第1圖,說明除濕機2的構成。 Fig. 1 is a system diagram of a dehumidifier 2 according to an embodiment of the present invention. The configuration of the dehumidifier 2 will be described with reference to Fig. 1 .
除濕機2,是對其外部(例如除濕對象之室內)的空氣(處理空氣)進行吸氣,並除濕而排氣。除濕機2,係具有處理空氣路徑4及再生空氣路徑6。於處理空氣路徑4的內部,流動有作為除濕對象的處理空氣。於再生空氣路徑6的內部,流動有再生空氣。 The dehumidifier 2 draws air (process air) to the outside (for example, a room to be dehumidified), and dehumidifies to exhaust. The dehumidifier 2 has a process air path 4 and a regeneration air path 6. Inside the process air path 4, process air as a dehumidification object flows. Inside the regeneration air path 6, regenerative air flows.
處理空氣路徑4,是從除濕機2的吸氣口8連接至排氣口10。於處理空氣路徑4中,配置有:主熱交換器(第1熱交換器)12、除濕轉輪14、副熱交換器(第2熱交換器)16、以及主風扇(第1風扇)18。又,處理空氣路徑4,是由第1處理空氣路徑4a、第2處理空 氣路徑4b、第3處理空氣路徑4c、及第4處理空氣路徑4d所成。第1處理空氣路徑4a,是從吸氣口8連接至主熱交換器12。第2處理空氣路徑4b,是從主熱交換器12連接至除濕轉輪14。第3處理空氣路徑4c,是從除濕轉輪14連接至副熱交換器16。第4處理空氣路徑4d,是從副熱交換器16連接至排氣口10,並在路徑上配置有主風扇18。因此,從吸氣口8朝向排氣口10,若以沿著處理空氣流動方向依順序而言,為配置有:主熱交換器12、除濕轉輪14、副熱交換器16、以及主風扇18。處理空氣,是藉由主風扇18從吸氣口8所吸氣,依順序通過主熱交換器12、除濕轉輪14、以及副熱交換器16,然後由排氣口10被排氣。不過,關於主風扇18的配置,並沒有特別地限定要在第4處理空氣路徑4d上,只要可以使處理空氣從吸氣口8往排氣口10流動,配置在處理空氣路徑4上的任一位置皆可。 The treatment air path 4 is connected from the intake port 8 of the dehumidifier 2 to the exhaust port 10. In the processing air path 4, a main heat exchanger (first heat exchanger) 12, a dehumidification rotor 14, a sub heat exchanger (second heat exchanger) 16, and a main fan (first fan) 18 are disposed. . Further, the processing air path 4 is made up of the first processing air path 4a and the second processing space. The gas path 4b, the third process air path 4c, and the fourth process air path 4d are formed. The first process air path 4a is connected from the intake port 8 to the main heat exchanger 12. The second process air path 4b is connected from the main heat exchanger 12 to the dehumidification wheel 14. The third process air path 4c is connected from the dehumidification rotor 14 to the sub heat exchanger 16. The fourth process air path 4d is connected from the sub heat exchanger 16 to the exhaust port 10, and the main fan 18 is disposed on the path. Therefore, from the intake port 8 toward the exhaust port 10, the main heat exchanger 12, the dehumidification rotor 14, the sub heat exchanger 16, and the main fan are disposed in order along the flow direction of the process air. 18. The process air is sucked from the intake port 8 by the main fan 18, passes through the main heat exchanger 12, the dehumidification rotor 14, and the sub heat exchanger 16 in order, and is then exhausted by the exhaust port 10. However, the arrangement of the main fan 18 is not particularly limited to be disposed on the fourth process air path 4d, as long as the process air can flow from the intake port 8 to the exhaust port 10, and is disposed on the process air path 4 A location is fine.
除濕轉輪14,是含有沸石(zeolite)等之吸濕材料,用以從通過此轉輪的處理空氣吸收水分(吸濕)。除濕轉輪14,由於其可及於整體並均等地吸濕,故將其形狀設成圓盤狀,以軸樞於中央而能夠旋轉。例如設置馬達般的驅動手段,藉此來旋轉驅動除濕轉輪14。 The dehumidification rotor 14 is a moisture absorbing material containing zeolite or the like for absorbing moisture (hygroscopic) from the process air passing through the rotor. Since the dehumidification rotor 14 can absorb moisture as a whole and uniformly, it has a disk shape and is pivotable at the center. For example, a motor-like driving means is provided, whereby the dehumidification rotor 14 is rotationally driven.
再生空氣路徑6,為閉路徑,於再生空氣路徑6上設置有再生風扇(第2風扇)20。藉由該再生風扇20,再生空氣,是在再生空氣路徑6的內部進行循環。於再生空氣路徑6中,配置有:再生風扇20、加熱器22、 除濕轉輪14、副熱交換器16、以及主熱交換器12。又,再生空氣路徑6,是由:第1再生空氣路徑6a、第2再生空氣路徑6b、第3再生空氣路徑6c、以及第4再生空氣路徑6d所成。第1再生空氣路徑6a,是從主熱交換器12連接至加熱器22,並在路徑上配置有再生風扇20。第2再生空氣路徑6b,是從加熱器22連接至除濕轉輪14。第3再生空氣路徑6c,是從除濕轉輪14連接至副熱交換器16。第4再生空氣路徑6d,是從副熱交換器16連接至主熱交換器12。因此,於再生空氣的循環方向上,依順序配置有:再生風扇20、加熱器22、除濕轉輪14、副熱交換器16、以及主熱交換器12。再生空氣,是以依順序通過加熱器22、除濕轉輪14、副熱交換器16、以及主熱交換器12,然後再次返回加熱器22的方式進行循環。不過,關於再生風扇20的配置,並沒有特別地限定,只要配置在再生空氣路徑6上的任一位置皆可。 The regeneration air path 6 is a closed path, and a regeneration fan (second fan) 20 is provided on the regeneration air path 6. The regeneration fan 20 regenerates the air and circulates inside the regeneration air path 6. In the regeneration air path 6, a regeneration fan 20, a heater 22, and The dehumidification rotor 14, the sub heat exchanger 16, and the main heat exchanger 12. Further, the regeneration air path 6 is formed by the first regeneration air path 6a, the second regeneration air path 6b, the third regeneration air path 6c, and the fourth regeneration air path 6d. The first regeneration air path 6a is connected from the main heat exchanger 12 to the heater 22, and the regeneration fan 20 is disposed on the path. The second regeneration air path 6b is connected from the heater 22 to the dehumidification rotor 14. The third regeneration air path 6c is connected from the dehumidification rotor 14 to the sub heat exchanger 16. The fourth regeneration air path 6d is connected from the sub heat exchanger 16 to the main heat exchanger 12. Therefore, in the circulation direction of the regeneration air, the regeneration fan 20, the heater 22, the dehumidification rotor 14, the sub heat exchanger 16, and the main heat exchanger 12 are disposed in this order. The regeneration air is circulated by sequentially passing the heater 22, the dehumidification rotor 14, the sub-heat exchanger 16, and the main heat exchanger 12, and then returning to the heater 22 again. However, the arrangement of the regenerative fan 20 is not particularly limited as long as it is disposed at any position on the regeneration air path 6.
加熱器22,例如為電氣加熱器,用以對進入除濕轉輪14的再生空氣加熱至預定的溫度。加熱器22是被配置在即將到達除濕轉輪14的跟前。 The heater 22, for example, an electric heater, is used to heat the regeneration air entering the dehumidification rotor 14 to a predetermined temperature. The heater 22 is disposed immediately before the dehumidification rotor 14 is reached.
主熱交換器12,是在:通過第1處理空氣路徑4a的除濕轉輪14之前的處理空氣,與通過第4再生空氣路徑6d的加熱器22之前的再生空氣之間,進行熱交換。第1處理空氣路徑4a內的處理空氣,由於是從吸氣口8進行吸氣後,通過除濕轉輪14之前的空氣,所以其溫度在系統整體當中較低。因此,在主熱交換器12中, 處理空氣是被加熱,再生空氣是被冷卻。 The main heat exchanger 12 exchanges heat between the process air before passing through the dehumidification rotor 14 of the first process air path 4a and the regeneration air before passing through the heater 22 of the fourth regeneration air path 6d. The process air in the first process air path 4a passes through the air before the dehumidification wheel 14 after inhaling from the intake port 8, so the temperature thereof is low in the entire system. Therefore, in the main heat exchanger 12, The process air is heated and the regeneration air is cooled.
副熱交換器16,是在:通過第3處理空氣路徑4c的除濕轉輪14之後的處理空氣,與通過第3再生空氣路徑6c的除濕轉輪14之後且通過主熱交換器12之前的再生空氣之間,進行熱交換。第3再生空氣路徑6c內的再生空氣,是以加熱器22加熱之後,通過第2再生空氣路徑6b及除濕轉輪14之後的再生空氣。由於由加熱器22所產生的熱量較大,所以第3再生空氣路徑6c內的再生空氣,其溫度是比第3處理空氣路徑4c內的處理空氣還高。因此,在副熱交換器16中,亦是處理空氣是被加熱,再生空氣是被冷卻。 The sub heat exchanger 16 is the process air after passing through the dehumidification rotor 14 of the third process air path 4c, and after the dehumidification wheel 14 passing through the third regeneration air path 6c and before and after passing through the main heat exchanger 12. Heat exchange between the air. The regeneration air in the third regeneration air passage 6c is the regeneration air that has passed through the second regeneration air passage 6b and the dehumidification rotor 14 after being heated by the heater 22. Since the amount of heat generated by the heater 22 is large, the temperature of the regeneration air in the third regeneration air path 6c is higher than the process air in the third process air path 4c. Therefore, in the sub heat exchanger 16, also the process air is heated and the regeneration air is cooled.
其次,參照第1圖說明除濕機2的作用。 Next, the action of the dehumidifier 2 will be described with reference to Fig. 1.
處理空氣,是從吸氣口8吸入空氣後,就經由第1處理空氣路徑4a而在主熱交換器12被加熱。被加熱後的處理空氣係經由第2處理空氣路徑4b而往除濕轉輪14流動。在除濕轉輪14中,處理空氣被除濕去除水分。被除濕後的處理空氣,經由第3處理空氣路徑4c而往副熱交換器16流動。在副熱交換器16中,處理空氣也是被加熱。被加熱後的處理空氣,經由第4處理空氣路徑4d然後通過主風扇18而從排氣口10被排氣。 The process air is heated in the main heat exchanger 12 via the first process air path 4a after the air is taken in from the intake port 8. The heated process air flows through the second process air path 4b to the dehumidification rotor 14. In the dehumidification rotor 14, the process air is dehumidified to remove moisture. The treated air after dehumidification flows to the sub heat exchanger 16 via the third process air path 4c. In the sub heat exchanger 16, the process air is also heated. The heated process air is exhausted from the exhaust port 10 via the fourth process air path 4d and then through the main fan 18.
再生空氣,是在再生空氣路徑6內進行循環。再生空氣,是通過再生風扇20而在加熱器22中被加熱,然後經由第2再生空氣路徑6b而往除濕轉輪14流動。在除濕轉輪14中,高溫的再生空氣從除濕轉輪14吸 收水分進行吸濕而將除濕轉輪14再生。在除濕轉輪14吸濕後的再生空氣是經由第3再生空氣路徑6c而往副熱交換器16流動。在副熱交換器16中,再生空氣被冷卻。被冷卻後之再生空氣的一部分因而冷凝。冷凝出之再生空氣的水分成為冷凝水而被回收。被冷卻後的再生空氣,經由第4再生空氣路徑6d而往主熱交換器12流動。在主熱交換器12中,再生空氣也是被冷卻。與副熱交換器16同樣地,被冷卻後之再生空氣的一部分冷凝,冷凝出之再生空氣的水分成為冷凝水而被回收。被冷卻後的再生空氣,經由第1再生空氣路徑6a後通過再生風扇20而往加熱器22流動。然後反覆此等作用。 The regeneration air is circulated in the regeneration air path 6. The regeneration air is heated by the heater 22 by the regeneration fan 20, and then flows to the dehumidification rotor 14 via the second regeneration air path 6b. In the dehumidification rotor 14, high-temperature regeneration air is sucked from the dehumidification wheel 14 The moisture removal is performed to absorb moisture to regenerate the dehumidification rotor 14. The regeneration air that has been absorbed by the dehumidification rotor 14 flows through the third regeneration air passage 6c to the sub heat exchanger 16. In the sub heat exchanger 16, the regeneration air is cooled. A portion of the regenerated air that has been cooled is thus condensed. The moisture of the condensed regeneration air is recovered as condensed water. The cooled regeneration air flows to the main heat exchanger 12 via the fourth regeneration air passage 6d. In the main heat exchanger 12, the regeneration air is also cooled. Similarly to the sub-heat exchanger 16, a part of the cooled regeneration air is condensed, and the condensed regeneration air is condensed and recovered. The regenerated air that has been cooled flows through the first regeneration air passage 6a and then passes through the regeneration fan 20 to the heater 22. Then repeat these effects.
如此地,於第1熱交換器及第2熱交換器之雙方中,係使再生空氣冷卻並冷凝。特別是,於副熱交換器16中,是在流入主熱交換器12之前藉由使再生空氣的一部分預先冷凝(預冷凝),而使得在主熱交換器12的冷卻全程成為冷凝現象。如此地在本實施形態的除濕機2中,是將主熱交換器12的冷凝效率最大化。因此,冷凝水的回收量增大,而可以提昇再生空氣的冷凝效率,藉此可以從除濕轉輪回收較多的水分,而可以提昇除濕轉輪的再生效率。因此,可以從通過除濕轉輪的處理空氣中吸取更多的濕氣,而可以提昇處理空氣的除濕效率。 As described above, in both of the first heat exchanger and the second heat exchanger, the regeneration air is cooled and condensed. In particular, in the sub-heat exchanger 16, by partially condensing (pre-condensing) a part of the regeneration air before flowing into the main heat exchanger 12, the entire cooling process of the main heat exchanger 12 becomes a condensation phenomenon. As described above, in the dehumidifier 2 of the present embodiment, the condensation efficiency of the main heat exchanger 12 is maximized. Therefore, the recovery amount of the condensed water is increased, and the condensation efficiency of the regeneration air can be increased, whereby more moisture can be recovered from the dehumidification runner, and the regeneration efficiency of the dehumidification runner can be improved. Therefore, it is possible to extract more moisture from the process air passing through the dehumidification rotor, and it is possible to improve the dehumidification efficiency of the process air.
為了使除濕效率更進一步地提昇,處理空氣及再生空氣,是成為從同方向進入除濕轉輪14其厚度方向之構成。於除濕轉輪14中,在處理空氣進入的面(進 入面)與脫離的面(脫離面),其水分的含有量是不同的。具體上,除濕轉輪14,其水分含有量為進入面較多於脫離面。這是因為處理空氣在從進入面朝向脫離面地通過除濕轉輪14時,會被慢慢地吸濕之故。因此,藉由設成使再生空氣從水分含有量較多的進入面進入之構成,可以回收更多除濕轉輪14的水分,而可以提昇除濕轉輪14的再生效率。 In order to further improve the dehumidification efficiency, the process air and the regeneration air are configured to enter the thickness direction of the dehumidification rotor 14 from the same direction. In the dehumidification wheel 14, in the face where the air is processed (into The amount of moisture contained in the surface and the detached surface (the detachment surface) is different. Specifically, the dehumidification rotor 14 has a moisture content of more than the exit surface. This is because the process air is slowly absorbed when passing through the dehumidification rotor 14 from the entry surface toward the release surface. Therefore, by setting the reconditioning air to enter from the inlet surface having a large water content, the moisture of the dehumidification rotor 14 can be recovered, and the regeneration efficiency of the dehumidification rotor 14 can be improved.
以下說明專利文獻1所揭示之以往之除濕機3的系統。 A system of the conventional dehumidifier 3 disclosed in Patent Document 1 will be described below.
第2圖為以往之除濕機3的系統圖。為了與本實施形態比較,以下參照第2圖來說明以往之除濕機3的構成。對於與第1圖所示之構成相同的部分,標示以相同的符號並會有省略說明之情形。 Fig. 2 is a system diagram of a conventional dehumidifier 3. In order to compare with this embodiment, the configuration of the conventional dehumidifier 3 will be described below with reference to Fig. 2 . The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
處理空氣路徑4的構成,是與本實施形態的除濕機2相同。 The configuration of the processing air path 4 is the same as that of the dehumidifier 2 of the present embodiment.
再生空氣路徑6,是除了流動於內部之再生空氣的循環方向,以及加熱器22和再生風扇20的位置之外,其他皆與本實施形態的除濕機2相同。具體上,在再生空氣的循環方向上,依順序配置有:加熱器22、除濕轉輪14、主熱交換器12、副熱交換器16、以及再生風扇20。再生空氣,是以依順序通過加熱器22、除濕轉輪14、主熱交換器12、以及副熱交換器16,然後再次返回加熱器22之方式進行循環。 The regeneration air path 6 is the same as the dehumidifier 2 of the present embodiment except for the circulation direction of the regeneration air flowing inside, and the positions of the heater 22 and the regeneration fan 20. Specifically, in the circulation direction of the regeneration air, the heater 22, the dehumidification rotor 14, the main heat exchanger 12, the sub heat exchanger 16, and the regeneration fan 20 are disposed in this order. The regeneration air is circulated by sequentially passing the heater 22, the dehumidification rotor 14, the main heat exchanger 12, and the sub heat exchanger 16, and then returning to the heater 22 again.
主熱交換器12,是在:通過處理空氣路徑4 的除濕轉輪14之前的處理空氣,與通過再生空氣路徑6的除濕轉輪14之後的再生空氣之間,進行熱交換。該處理空氣,由於是從吸氣口8進行吸氣後,通過除濕轉輪14之前的空氣,所以其溫度在系統整體當中較低。因此,在主熱交換器12中,處理空氣是被加熱,再生空氣是被冷卻。 The main heat exchanger 12 is at: through the process air path 4 Heat exchange is performed between the process air before the dehumidification rotor 14 and the regeneration air after passing through the dehumidification rotor 14 of the regeneration air path 6. Since the treated air passes through the air before the humidifying rotor 14 after being sucked from the intake port 8, the temperature thereof is low in the entire system. Therefore, in the main heat exchanger 12, the process air is heated and the regeneration air is cooled.
副熱交換器16,是在:通過處理空氣路徑4的除濕轉輪14之後的處理空氣,與通過再生空氣路徑6的加熱器22之前的再生空氣之間,進行熱交換。該再生空氣,是透過主熱交換器12而在系統之中與低溫的處理空氣熱交換之後的再生空氣。相對於此,處理空氣,是通過主熱交換器12及除濕轉輪14而被加熱。因此,通過處理空氣路徑4的除濕轉輪14之後的處理空氣,其溫度是高於通過再生空氣路徑6的加熱器22之前的再生空氣。因此,在副熱交換器16中,處理空氣是被冷卻,再生空氣是被加熱。 The sub-heat exchanger 16 performs heat exchange between the process air after passing through the dehumidification rotor 14 of the process air path 4 and the regeneration air before passing through the heater 22 of the regeneration air path 6. The regeneration air is regenerative air that has passed through the main heat exchanger 12 and is exchanged with the low-temperature process air in the system. On the other hand, the process air is heated by the main heat exchanger 12 and the dehumidification rotor 14. Therefore, by processing the process air after the dehumidification rotor 14 of the air path 4, the temperature is higher than the regeneration air before the heater 22 passing through the regeneration air path 6. Therefore, in the sub heat exchanger 16, the process air is cooled and the regeneration air is heated.
其次,參照第2圖來說明以往之除濕機3的作用。 Next, the action of the conventional dehumidifier 3 will be described with reference to Fig. 2 .
處理空氣,是從吸氣口8吸入空氣後,在主熱交換器12被加熱。被加熱後的處理空氣往除濕轉輪14流動。在除濕轉輪14中,處理空氣被除濕去除水分。被除濕後的處理空氣,往副熱交換器16流動。在副熱交換器16中,處理空氣是被冷卻。被冷卻後的處理空氣,通過主風扇18而從排氣口10被排氣。 The process air is heated in the main heat exchanger 12 after the air is taken in from the intake port 8. The heated process air flows to the dehumidification rotor 14. In the dehumidification rotor 14, the process air is dehumidified to remove moisture. The treated air after dehumidification flows to the sub heat exchanger 16. In the sub heat exchanger 16, the process air is cooled. The cooled process air is exhausted from the exhaust port 10 by the main fan 18.
再生空氣,是在再生空氣路徑6內進行循環。再生空氣,是在加熱器22被加熱,然後往除濕轉輪14流動。在除濕轉輪14中,高溫的再生空氣從除濕轉輪14吸收水分進行吸濕而將除濕轉輪14再生。在除濕轉輪14吸濕後的再生空氣是往主熱交換器12流動。在主熱交換器12中,再生空氣被冷卻。被冷卻後之再生空氣的一部分因而冷凝。冷凝出之再生空氣的水分成為冷凝水而被回收。被冷卻後的再生空氣,往副熱交換器16流動。在副熱交換器16中,再生空氣被加熱。被加熱後的再生空氣,通過再生風扇20而往加熱器22流動。然後反覆此等作用。 The regeneration air is circulated in the regeneration air path 6. The regeneration air is heated in the heater 22 and then flows to the dehumidification rotor 14. In the dehumidification rotor 14, the high-temperature regeneration air absorbs moisture from the dehumidification rotor 14 to absorb moisture to regenerate the dehumidification rotor 14. The regeneration air after the dehumidification rotor 14 absorbs moisture flows toward the main heat exchanger 12. In the main heat exchanger 12, the regeneration air is cooled. A portion of the regenerated air that has been cooled is thus condensed. The moisture of the condensed regeneration air is recovered as condensed water. The cooled regeneration air flows to the sub heat exchanger 16. In the sub heat exchanger 16, the regeneration air is heated. The heated regeneration air flows through the regeneration fan 20 to the heater 22. Then repeat these effects.
處理空氣及再生空氣,相對於除濕轉輪14是成為從不同方向進入其厚度方向的構成。因此,除濕轉輪14的再生效率是比從同方向進入之情形還低。 The treatment air and the regeneration air are configured to enter the thickness direction from different directions with respect to the dehumidification rotor 14. Therefore, the regeneration efficiency of the dehumidification rotor 14 is lower than the case of entering from the same direction.
對於本實施形態之除濕機2與以往之除濕機3的不同,參照第3圖進行說明。 The difference between the dehumidifier 2 of the present embodiment and the conventional dehumidifier 3 will be described with reference to FIG.
第3圖,是表示本實施形態之除濕機2與以往之除濕機3的再生空氣的濕空氣線圖。對於本實施形態的除濕機2是以實線表示,對於以往的除濕機3是以虛線表示。圖面中的縱軸是顯示絕對濕度(水分量),橫軸是顯示溫度。 Fig. 3 is a wet air diagram showing the regeneration air of the dehumidifier 2 of the present embodiment and the conventional dehumidifier 3. The dehumidifier 2 of the present embodiment is indicated by a solid line, and the conventional dehumidifier 3 is indicated by a broken line. The vertical axis in the drawing shows the absolute humidity (water content) and the horizontal axis shows the display temperature.
若一併參照第1圖時,是以在第1圖中之系統圖的點,與其對應在第3圖之濕空氣線圖中的點的記號來顯示。本實施形態之除濕機2的再生空氣,是藉由加熱 器22所加熱,其溫度在循環路徑中成為最大(點X1)。通過除濕轉輪14而對除濕轉輪14中的水分進行吸濕,其絕對濕度成為最大(點X2)。在副熱交換器16被冷卻,越過露點(點X2’)使其一部分冷凝(點X3)。在此的點X2’及點X3,是位在表示飽和濕度的曲線上,在該曲線上,相對濕度為100%。因此,在該曲線上只要溫度降低時就會發生冷凝。然後,在主熱交換器12更進一步冷卻及冷凝,其絕對濕度成為最低(點X4)。然後藉由加熱器22加熱,再次使其溫度成為最大(點X1)。 When referring to Fig. 1 together, it is displayed at the point of the system diagram in Fig. 1 and the symbol corresponding to the point in the wet air line diagram of Fig. 3. The regeneration air of the dehumidifier 2 of the present embodiment is heated by the heater 22, and its temperature becomes maximum in the circulation path (point X 1 ). The moisture in the dehumidification rotor 14 is absorbed by the dehumidification rotor 14, and its absolute humidity becomes maximum (point X 2 ). The sub-heat exchanger 16 is cooled and partially condensed (point X 3 ) beyond the dew point (point X 2 '). The point X 2 ' and the point X 3 here are on a curve indicating saturation humidity, on which the relative humidity is 100%. Therefore, condensation occurs on the curve as long as the temperature is lowered. Then, the main heat exchanger 12 is further cooled and condensed, and its absolute humidity is the lowest (point X 4 ). Then, by heating by the heater 22, the temperature is again maximized (point X 1 ).
如此地,於主熱交換器12及副熱交換器16之雙方中,由於是將再生空氣冷凝。因此,冷凝水的回收量增大,而可以提昇再生空氣的冷凝效率,因此,可以從除濕轉輪14回收較多的水分,而可以提昇處除濕轉輪14的再生效率。 As described above, both of the main heat exchanger 12 and the sub heat exchanger 16 condense the regeneration air. Therefore, the amount of recovery of the condensed water is increased, and the condensation efficiency of the regeneration air can be increased. Therefore, more moisture can be recovered from the dehumidification rotor 14, and the regeneration efficiency of the dehumidification rotor 14 can be improved.
在副熱交換器16中,即使沒有到達冷凝,而只有使溫度降低亦可(點X2-點X3’)。此情形時,在主熱交換器12中,使溫度降低至露點之後(點X3’-點X2’),再生空氣被冷凝(點X2’-點X4)。又,在從副熱交換器16至主熱交換器12為止的第4再生空氣路徑6d中進行散熱,而使再生空氣的溫度降低至露點亦可(點X3’-點X2’)。此情形時,在主熱交換器12中,在冷卻的全過程中使再生空氣被冷凝(點X2’-點X4)。又,在副熱交換器16中使再生空氣的溫度降低至露點亦可(點X2-點X2’)。此情形時,同樣地副熱交換器16雖沒有發生冷 凝,但在主熱交換器12中,在冷卻的全過程中使再生空氣被冷凝(點X2’-點X4)。以如此方式實施,來使主熱交換器12的冷凝效率提昇亦可。 In the sub-heat exchanger 16, even if the condensation is not reached, only the temperature is lowered (point X 2 - point X 3 '). In this case, in the main heat exchanger 12, after the temperature is lowered to the dew point (point X 3 '-point X 2 '), the regeneration air is condensed (point X 2 '-point X 4 ). Further, heat is dissipated in the fourth reconditioning air passage 6d from the sub heat exchanger 16 to the main heat exchanger 12, and the temperature of the reconditioning air may be lowered to the dew point (point X 3 '-point X 2 '). In this case, in the main heat exchanger 12, the regeneration air is condensed in the entire process of cooling (point X 2 '-point X 4 ). Further, in the sub-heat exchanger 16, the temperature of the regeneration air may be lowered to the dew point (point X 2 - point X 2 '). In this case, similarly, the sub-heat exchanger 16 does not condense, but in the main heat exchanger 12, the reconditioning air is condensed during the entire cooling process (point X 2 '-point X 4 ). It is carried out in such a manner that the condensation efficiency of the main heat exchanger 12 can be improved.
若合併參照第2圖時,是以在第2圖之系統圖中的點,與其對應在第3圖之濕空氣線圖中的點的記號來顯示。以往之除濕機3的再生空氣,是藉由加熱器22所加熱,其溫度在循環路徑中成為最大(點Y1)。通過除濕轉輪14而對除濕轉輪14中的水分進行吸濕,其絕對濕度成為最大(點Y2)。在主熱交換器12越過露點(點Y2’)被冷卻及冷凝,其絕對濕度成為最低(點Y3)。在此的點Y2’及點Y3,是位在表示飽和濕度的曲線上。由於表示飽和濕度的曲線是由再生空氣的物性值所決定,故本實施形態與以往例之飽和濕度曲線為共通。其後,在副熱交換器16被加熱而使溫度上昇(點Y4)。然後藉由加熱器22加熱,再次使溫度成為最大(點Y1)。 When the reference is made to Fig. 2, it is indicated by the point in the system diagram of Fig. 2, and the point corresponding to the point in the wet air line diagram of Fig. 3. In the conventional dehumidifier 3, the regeneration air is heated by the heater 22, and its temperature becomes maximum in the circulation path (point Y 1 ). The moisture in the dehumidification rotor 14 is absorbed by the dehumidification rotor 14, and its absolute humidity becomes maximum (point Y 2 ). When the main heat exchanger 12 passes through the dew point (point Y 2 '), it is cooled and condensed, and its absolute humidity is the lowest (point Y 3 ). The point Y 2 ' and the point Y 3 here are on the curve indicating the saturation humidity. Since the curve indicating the saturation humidity is determined by the physical property value of the regeneration air, the present embodiment is common to the saturation humidity curve of the conventional example. Thereafter, the sub-heat exchanger 16 is heated to raise the temperature (point Y 4 ). Then, by heating by the heater 22, the temperature is again maximized (point Y 1 ).
對本實施形態與以往例之不同進行說明,在本實施形態的除濕機2中,相對於再生空氣在副熱交換器16中是被冷卻,而在以往的除濕機3是被加熱。在在本實施形態的除濕機2中,在由主熱交換器12進行冷凝之前,是以將再生空氣的一部分開始冷凝之方式來進行預先冷凝(點X2’-點X3)。藉由如此地實施,流入主熱交換器12的再生空氣,由於是已經位在飽和濕度曲線上(點X3),溫度一下降的同時就產生冷凝(點X3-點X4)。不過,在以往的除濕機3,通過除濕轉輪14進行吸濕的再 生空氣並沒有被預先冷凝便往主熱交換器12流入。因此,在要開始冷凝之前必須要有一定溫度量的冷卻(點Y2-點Y2’)。因此,以往的除濕機3相較於本實施形態的除濕機2,冷凝量降低(HX>HY)。又,如先前所記載,即使在副熱交換器16中沒有產生冷凝之情形時(點X2-點X3’或是點X2-點X2’),相較於以往,仍可提升冷凝效率。故相較於以往的除濕機3達到主熱交換器12形成冷凝的溫度降低量(點Y2-點Y2’),由於本實施形態的除濕機2要達到形成冷凝的溫度降低量(點X3’-點X2’或是零)較少,所以可有效率地進行冷凝。 The difference between the present embodiment and the conventional example will be described. In the dehumidifier 2 of the present embodiment, the sub-heat exchanger 16 is cooled with respect to the regeneration air, and the conventional dehumidifier 3 is heated. In the dehumidifier 2 of the present embodiment, before the condensation by the main heat exchanger 12, the condensation is performed in advance (point X 2 '-point X 3 ) so that a part of the regeneration air starts to condense. By doing so, the regeneration air flowing into the main heat exchanger 12 is already on the saturation humidity curve (point X 3 ), and condensation occurs at the same time as the temperature is lowered (point X 3 - point X 4 ). However, in the conventional dehumidifier 3, the regeneration air that has been absorbed by the dehumidification rotor 14 is not condensed beforehand and flows into the main heat exchanger 12. Therefore, there must be a certain amount of cooling (point Y 2 - point Y 2 ') before starting condensation. Therefore, the conventional dehumidifier 3 has a smaller amount of condensation (H X >H Y ) than the dehumidifier 2 of the present embodiment. Further, as described above, even when condensation does not occur in the sub-heat exchanger 16 (point X 2 - point X 3 ' or point X 2 - point X 2 '), it is improved compared to the past. Condensation efficiency. Therefore, compared with the conventional dehumidifier 3, the temperature reduction amount (point Y 2 - point Y 2 ') at which the main heat exchanger 12 is condensed is formed, and the dehumidifier 2 of the present embodiment is required to reach a temperature decrease amount of condensation (point X 3 '-point X 2 ' or zero) is less, so condensation can be performed efficiently.
再者,如第1圖及第2圖所示,相對於除濕轉輪14,本實施形態與以往技術在處理空氣與再生空氣的進入方向不同。如先前所記載,為了使再生空氣從除濕轉輪14吸收更多水分進行吸濕,相對於除濕轉輪14是以從同方向進入較為有利。對於此點若以第3圖來看,比較從點X1到點X2之直線的傾斜與從點Y1到點Y2之直線的傾斜,是從點X1到點X2之直線的傾斜較大。可以得知由於藉由再生空氣通過除濕轉輪14會形成一定程度的溫度下降,傾斜較大之情形者是對更多的水分進行吸濕者。 Further, as shown in FIGS. 1 and 2, the present embodiment differs from the prior art in the entry direction of the process air and the regeneration air with respect to the dehumidification rotor 14. As described above, in order to absorb moisture from the dehumidification rotor 14 to absorb moisture, it is advantageous to enter the same direction with respect to the dehumidification rotor 14. For this point, as seen in Fig. 3, the inclination of the straight line from the point X 1 to the point X 2 and the inclination of the straight line from the point Y 1 to the point Y 2 are straight lines from the point X 1 to the point X 2 . Tilt is large. It can be seen that since a certain degree of temperature drop is formed by the regeneration air passing through the dehumidification rotor 14, the situation in which the inclination is large is to absorb more moisture.
又,本發明的除濕機,例如除了使室內乾燥為目的之以室內空氣作為除濕對象之外,亦包含以衣類乾燥為目的之以衣類的水分作為除濕對象者、或者用以達成此等雙方之目的者。 Further, the dehumidifier of the present invention includes, for example, indoor air as a dehumidification target for drying indoors, and moisture for clothing for drying purposes, or for achieving both of them. Target person.
