Description

除濕裝置 Dehumidifier

本發明係有關於一種除濕裝置。 The present invention relates to a dehumidification apparatus.

以往,在將乾燥劑與熱泵組合的除濕裝置,提議具有如下之構件者,2條風路,係相對濕度相異的空氣流動,並彼此被劃分;及乾燥劑材料,係轉動自如地配置成跨在該2條風路,並載持進行水分之吸附、脫附的吸附劑(例如,參照專利文獻1)。 Conventionally, in a dehumidifying device that combines a desiccant and a heat pump, it is proposed to have the following components, two air passages, which are different in relative humidity, and are divided into each other; and the desiccant material is rotatably arranged The adsorbent which adsorbs and desorbs moisture is carried in the two air passages (for example, refer patent document 1).

在專利文獻1所記載之技術係藉由使構成圓板狀之乾燥劑材料轉動,因應於風路的相對濕度,產生吸附空氣中之水分的吸附反應及將所吸附之水分脫附於空氣的脫附反應。 The technique described in Patent Document 1 generates an adsorption reaction for adsorbing moisture in the air and desorbs the adsorbed moisture to the air by rotating the desiccant material constituting the disk shape in response to the relative humidity of the air passage. Desorption reaction.

又,在專利文獻1所記載之技術係為了利用從熱泵所產生之凝結熱的一部分,而將風路二分割,使通過乾燥劑材料之空氣的相對濕度降低,以促進脫附反應,而剩下的凝結熱係直接向除濕對象空間排出。 Further, in the technique described in Patent Document 1, in order to utilize a part of the heat of condensation generated from the heat pump, the air passage is divided into two, and the relative humidity of the air passing through the desiccant material is lowered to promote the desorption reaction. The lower condensation heat is directly discharged to the dehumidification object space.

【先行專利文獻】 [Prior patent documents] 【專利文獻】 [Patent Literature]

[專利文獻1]日本專利4649967號(例如申請專利範圍第1項) [Patent Document 1] Japanese Patent No. 4,649,967 (for example, Patent Application No. 1)

專利文獻1所記載之技術係藉由使乾燥劑材料轉動,而產生吸附反應及脫附反應。因此,在作為乾燥劑材料的轉動機構,例如需要馬達等,而具有製造費用增加、或耗電力增大、或機器構成變得複雜的課題。 The technique described in Patent Document 1 generates an adsorption reaction and a desorption reaction by rotating a desiccant material. Therefore, in the rotating mechanism as the desiccant material, for example, a motor or the like is required, and there is a problem that the manufacturing cost increases, the power consumption increases, or the machine configuration becomes complicated.

在專利文獻1所記載之技術係設置彼此被劃分的2條風路。在風路間空氣洩漏時,因所洩漏的空氣而在阻礙吸附反應或脫附反應的方向作用。因此,配置成跨在2條風路之乾燥劑材料係被設置成與跨在風路的部分接觸。 In the technique described in Patent Document 1, two air passages that are divided from each other are provided. When the air leaks between the wind passages, it acts in a direction that hinders the adsorption reaction or the desorption reaction due to the leaked air. Therefore, the desiccant material configured to straddle the two air paths is placed in contact with the portion that straddles the air path.

即,因為在專利文獻1所記載之技術係為了避免風路間之空氣的洩漏,而乾燥劑材料與劃分風路的部分滑動,所以因滑動而馬達扭力需要變大、而具有耗電力變大的課題。 In other words, in the technique described in Patent Document 1, in order to prevent leakage of air between the air passages, the desiccant material and the portion dividing the air passage are slid, so that the motor torque needs to be increased due to the sliding, and the power consumption is increased. Question.

因為在專利文獻1所記載之技術係乾燥劑材料與劃分風路的部分滑動,所以構件彼此相摩擦而受損,因風路間之空氣的洩漏,而具有吸附及脫附之效率降低的課題,而且需要用以修補該損傷的維修,而具有耗費上漲的課題。 In the technique described in Patent Document 1, the desiccant material and the portion dividing the air passage are slid, so that the members are rubbed against each other and damaged, and the efficiency of adsorption and desorption is lowered due to leakage of air between the air passages. And it is necessary to repair the repair of the damage, and it has a problem of rising costs.

因為在專利文獻1所記載之技術係將凝結熱的一部分用作乾燥劑之脫附反應的熱源,所以需要2條風路,而具有機器構成變得複雜的課題,而且因為壓力損失增加,風扇之動力增加,而具有耗電力增加的課題。 In the technique described in Patent Document 1, a part of the heat of condensation is used as a heat source for the desorption reaction of the desiccant. Therefore, two air passages are required, which has a problem that the machine configuration is complicated, and the fan is increased in pressure loss. The power is increased, and there is a problem of increasing power consumption.

在專利文獻1所記載之技術係在外氣溫度低時驅動附設於室外熱交換器的加熱器,抑制室外熱交換器的著霜。可是,在露點溫度成為冰點以下的情況,因為難抑制在熱交換器所產生之著霜,所以需要除霜運轉,而具有每小時之除濕量 大為降低的課題。 The technique described in Patent Document 1 drives a heater attached to an outdoor heat exchanger when the outside air temperature is low, and suppresses frosting of the outdoor heat exchanger. However, when the dew point temperature is below the freezing point, it is difficult to suppress the frost generated in the heat exchanger, so the defrosting operation is required, and the dehumidification amount per hour is required. A problem that is greatly reduced.

本發明係為了解決如上述所示之課題中的至少一個而開發的,其目的在於提供一種除濕裝置,該除濕裝置係用以實現抑制費用上升、抑制耗電力、抑制機器構成之複雜化、及抑制吸附、脫附之效率的降低。 The present invention has been made in order to solve at least one of the problems described above, and an object of the invention is to provide a dehumidifying apparatus for suppressing an increase in cost, suppressing power consumption, and suppressing complication of a device configuration, and Reduce the efficiency of adsorption and desorption.

The air that has passed through the first heat exchanger 11a is cooled to a dew point temperature or lower, and is dehumidified air (1-2), and then sent to the moisture adsorbing means 16.

因為冷卻除濕後之空氣的相對濕度係高達約70~90%RH,所以水分吸附手段16的吸附劑易吸附水分。冷卻後的空氣被水分吸附手段16之吸附劑吸附水分而除濕後,變成高溫低濕, 並流入第2熱交換器11b(1-3)。 Since the relative humidity of the air after cooling and dehumidification is as high as about 70 to 90% RH, the adsorbent of the moisture adsorbing means 16 easily adsorbs moisture. The cooled air is adsorbed by the adsorbent of the moisture adsorbing means 16 and dehumidified, and becomes high temperature and low humidity. The second heat exchanger 11b (1-3) flows into the second heat exchanger 11b.

因為第2熱交換器11b係作為凝結器發揮功能,所以被加熱,而使通過空氣的溫度上升(1-4)。 Since the second heat exchanger 11b functions as a condenser, it is heated to raise the temperature of the passing air (1-4).

通過第2熱交換器11b後的空氣係流入第3熱交換器11c。因為第3熱交換器11c係作為凝結器發揮功能,所以使通過空氣的溫度上升(1-5),並自排出口被排出至除濕對象空間。 The air that has passed through the second heat exchanger 11b flows into the third heat exchanger 11c. Since the third heat exchanger 11c functions as a condenser, the temperature of the passing air is raised (1-5), and is discharged to the dehumidification target space from the discharge port.

(第2運轉模式之濕空氣線圖) (wet air line diagram in the second operation mode)

在第2運轉模式,自吸入口被取入風路內的空氣(2-1)係被送入第1熱交換器11a。 In the second operation mode, the air (2-1) taken into the air passage from the suction port is sent to the first heat exchanger 11a.

在此,被取入風路內的空氣係藉作用為凝結器之第1熱交換器11a所加熱,而通過空氣的溫度上升(2-2)後,被送入水分吸附手段16。 Here, the air taken into the air passage is heated by the first heat exchanger 11a serving as a condenser, and the temperature of the passing air rises (2-2), and then sent to the moisture adsorbing means 16.

因為加熱後之空氣的相對濕度係比流入空氣更低,所以水分吸附手段16的吸附劑易脫附水分。加熱後的空氣被水分吸附手段16之吸附劑脫附水分而加濕後,變成低溫高濕,並流入第2熱交換器11b(2-3)。 Since the relative humidity of the heated air is lower than that of the inflowing air, the adsorbent of the moisture adsorbing means 16 tends to desorb moisture. The heated air is desorbed by the adsorbent of the moisture adsorbing means 16 and humidified, and then becomes low temperature and high humidity, and flows into the second heat exchanger 11b (2-3).

因為第2熱交換器11b係作為蒸發器發揮功能,所以冷卻通過空氣,而在冷卻後之通過空氣的溫度被冷卻至露點溫度以下的情況,成為水分被除濕的除濕空氣(2-4)。 Since the second heat exchanger 11b functions as an evaporator, the air is cooled and passed through the air, and the temperature of the passing air after cooling is cooled to a temperature equal to or lower than the dew point temperature, thereby dehumidifying the air (2-4).

通過第2熱交換器11b後的空氣係流入第3熱交換器11c。因為第3熱交換器11c係作為凝結器發揮功能,所以使通過空氣的溫度上升(2-5),並自排出口被排出至除濕對象空間。 The air that has passed through the second heat exchanger 11b flows into the third heat exchanger 11c. Since the third heat exchanger 11c functions as a condenser, the temperature of the passing air is raised (2-5), and is discharged from the discharge port to the dehumidification target space.

[變形例] [Modification]

此外,如以下之說明所示,第1熱交換器11a及第3熱交換器11c係藉由調整導熱面積之比,可抑制除濕效率降低。 Further, as described below, the first heat exchanger 11a and the third heat exchanger 11c can suppress the decrease in the dehumidification efficiency by adjusting the ratio of the heat transfer area.

例如,在設想除濕對象空間是夏季之室內的情況(溫度27℃、濕度約60%)。在執行第2運轉模式時,若第1熱交換器11a的加熱量大,則水分吸附手段16之放濕量成為第2熱交換器11b之除濕容量以上,而除濕效率降低。 For example, it is assumed that the dehumidification target space is in the summer room (temperature: 27 ° C, humidity: about 60%). When the heating amount of the first heat exchanger 11a is large, the amount of moisture released by the moisture adsorbing means 16 becomes equal to or higher than the dehumidifying capacity of the second heat exchanger 11b, and the dehumidifying efficiency is lowered.

因此,藉由使第3熱交換器11c之導熱面積比第1熱交換器11a的大,抑制第1熱交換器11a的凝結熱量,而抑制流入空氣的過加熱,可抑制除濕效率降低。 Therefore, by making the heat transfer area of the third heat exchanger 11c larger than that of the first heat exchanger 11a, the heat of condensation of the first heat exchanger 11a is suppressed, and overheating of the inflowing air is suppressed, and the deterioration of the dehumidification efficiency can be suppressed.

又,在除濕對象空間之空氣的相對濕度比上述之說明更高的情況(溫度27℃、濕度約80%),可如以下所示調整導熱面積之比。 Further, in the case where the relative humidity of the air in the dehumidification target space is higher than the above description (temperature: 27 ° C, humidity: about 80%), the ratio of the heat transfer area can be adjusted as shown below.

在執行第2運轉模式時,若未使流入水分吸附手段16之空氣的相對濕度降低,則脫附反應所造成之放濕量變少。依此方式,在水分吸附手段16放濕量變少,意指無法使流入下游側的第2熱交換器11b之空氣的濕度提高對應的量。即,在第2熱交換器11b之除濕量減少了無法使流入第2熱交換器11b之空氣的濕度提高的量,而除濕效率降低。 When the second operation mode is executed, if the relative humidity of the air flowing into the moisture adsorption means 16 is not lowered, the amount of moisture released by the desorption reaction is reduced. In this way, the amount of moisture released by the moisture adsorbing means 16 is small, which means that the humidity of the air flowing into the second heat exchanger 11b on the downstream side cannot be increased by a corresponding amount. In other words, the amount of dehumidification in the second heat exchanger 11b is reduced by an amount that prevents the humidity of the air flowing into the second heat exchanger 11b from increasing, and the dehumidification efficiency is lowered.

因此,藉由使第1熱交換器11a之導熱面積比第3熱交換器11c的大,可使流入第1熱交換器11a之空氣的加熱量增加。藉此,因為相對濕度降低後之乾燥空氣流入水分吸附手段16,所以脫附量增加,而相對濕度變高、焓亦高的空氣流入第2熱交換器11b,而可抑制除濕效率降低。 Therefore, by making the heat transfer area of the first heat exchanger 11a larger than that of the third heat exchanger 11c, the amount of heating of the air flowing into the first heat exchanger 11a can be increased. By this means, since the dry air having a reduced relative humidity flows into the moisture adsorbing means 16, the amount of desorption increases, and the air having a high relative humidity and high helium flows into the second heat exchanger 11b, thereby suppressing a decrease in the dehumidifying efficiency.

[本第1實施形態之除濕裝置300所具有的效果] [Effects of the dehumidifying apparatus 300 of the first embodiment]

因為本第1實施形態之除濕裝置300係在水分吸附手段16未設置如乾燥劑轉子等之馬達者,所以製造費用增加、或耗電力增加、或機器構成變得複雜等不存在。 The dehumidifier 300 of the first embodiment is not provided with a motor such as a desiccant rotor in the moisture adsorbing means 16, so that the manufacturing cost is increased, the power consumption is increased, or the machine configuration is complicated.

因為本第1實施形態之除濕裝置300係不是配置成乾燥劑轉子跨在所劃分之2條風路者,所以不會阻礙風路間之空氣的洩漏所造成之吸附反應或脫附反應。又,可防止劃分風路之部分與乾燥劑轉子之滑動所造成的耗電力增大及因滑動而受損之構件的維修所造成的耗費增大。 Since the dehumidifying apparatus 300 according to the first embodiment is not disposed so that the desiccant rotor straddles the two divided air passages, the adsorption reaction or the desorption reaction caused by the leakage of air between the air passages is not hindered. Further, it is possible to prevent an increase in power consumption caused by the sliding of the portion of the air passage and the drying of the desiccant rotor, and an increase in the cost of maintenance of the member damaged by the sliding.

因為本第1實施形態之除濕裝置300係將凝結熱的一部分用作乾燥劑之脫附反應的熱源,所以在不需要劃分之2條風路上,機器構成變得比較簡單。又,可防止因2條風路而壓力損失增大而提高送風手段12之轉速所伴隨之耗電力的增大。 Since the dehumidifier 300 of the first embodiment uses a part of the heat of condensation as a heat source for the desorption reaction of the desiccant, the machine configuration is relatively simple on the two air passages that do not need to be divided. Further, it is possible to prevent an increase in power consumption accompanying an increase in the pressure loss of the air blowing means 12 due to an increase in pressure loss due to the two air passages.

本第1實施形態之除濕裝置300係在熱交換器11發生著霜的情況,可切換四通閥15而實施除霜運轉,但是在該除霜運轉時亦可對除濕對象空間提供除濕空氣,而可抑制每小時之除濕量降低。 In the dehumidifier 300 of the first embodiment, when the heat exchanger 11 is frosted, the four-way valve 15 can be switched to perform the defrosting operation. However, during the defrosting operation, dehumidified air can be supplied to the dehumidification target space. It can suppress the decrease in the amount of dehumidification per hour.

在以往之使水分吸附手段轉動的方式,在低溫(例如溫度10℃、濕度60%)下運轉時,以加熱器等對水分吸附手段之脫附前的空氣加熱,使溫度高的空氣流入蒸發器,藉此,使蒸發溫度上升,抑制著霜,但是在更低溫(例如溫度5℃、濕度60%)等,加熱器等之加熱手段的輸入變成過大或發生著霜。在發生著霜的情況,需要每隔固定時間使冷凍循環停止,或藉 加熱器輸入進行除霜運轉,而除濕量降低。 In the conventional method of rotating the moisture adsorbing means, when operating at a low temperature (for example, a temperature of 10 ° C and a humidity of 60%), the air before the desorption of the moisture adsorbing means by a heater or the like is heated to cause the air having a high temperature to flow into the evaporation. In this way, the evaporating temperature is raised to suppress the frost, but at a lower temperature (for example, a temperature of 5 ° C and a humidity of 60%), the input of the heating means such as a heater becomes excessive or frosting occurs. In the case of frost, it is necessary to stop the freezing cycle at regular intervals, or to borrow The heater input performs a defrosting operation, and the amount of dehumidification is lowered.

可是,本第1實施形態之除濕裝置300係使第1熱交換器11a作為蒸發器發揮功能,即使發生著霜,亦藉由切換四通閥15,可一面使第1熱交換器11a作為凝結器發揮功能,進行除霜,一面使第2熱交換器11b作為蒸發器發揮功能,進行除濕。又,使第2熱交換器11b作為蒸發器發揮功能,即使發生著霜,亦藉由切換四通閥15,可一面使第2熱交換器11b作為凝結器發揮功能,進行除霜,一面使第1熱交換器11a作為蒸發器發揮功能,並以水分吸附手段16進行除濕。 In the dehumidifier 300 of the first embodiment, the first heat exchanger 11a functions as an evaporator, and even if frost occurs, the first heat exchanger 11a can be condensed by switching the four-way valve 15. When the defrosting function is performed, the second heat exchanger 11b functions as an evaporator to perform dehumidification. In addition, the second heat exchanger 11b functions as an evaporator, and even if frost is generated, the second heat exchanger 11b can be operated as a condenser and the defrosting can be performed while switching the four-way valve 15. The first heat exchanger 11a functions as an evaporator and is dehumidified by the moisture adsorbing means 16.

依此方式,本第1實施形態之除濕裝置300係在露點溫度為冰點以下的情況,亦藉由切換四通閥15,實施除霜運轉,可一面對除濕對象空間提供除濕空氣一面進行除霜,而可抑制每小時之除濕量降低。 In this way, the dehumidifying apparatus 300 of the first embodiment is configured such that when the dew point temperature is equal to or lower than the freezing point, the defrosting operation is performed by switching the four-way valve 15, and the dehumidifying air can be supplied to the dehumidifying object space. Cream, which can reduce the amount of dehumidification per hour.

因為本第1實施形態之除濕裝置300係在第1運轉模式時可將水分吸附手段16之全部的面用於吸附,所以可使除濕量比使用乾燥劑轉子等之以往的除濕裝置大。即,在使用與乾燥劑轉子同體積之水分吸附手段16的情況,可產生比以往之方式更低濕的空氣,而可使衣服乾燥速度變快。 Since the dehumidifying apparatus 300 according to the first embodiment can use the entire surface of the moisture adsorbing means 16 for adsorption in the first operational mode, the dehumidification amount can be made larger than that of the conventional dehumidifying apparatus using a desiccant rotor or the like. That is, in the case where the moisture adsorbing means 16 having the same volume as the desiccant rotor is used, it is possible to generate air which is lower in humidity than in the conventional method, and the drying speed of the clothes can be made faster.

本第1實施形態之除濕裝置300係可執行第1運轉模式及第2運轉模式。 The dehumidification apparatus 300 according to the first embodiment can execute the first operation mode and the second operation mode.

因此,在執行第2運轉模式時,因水分吸附手段16之脫附反應而空氣溫度降低,進而,通過作為蒸發器發揮功能之第2熱交換器11b而被冷卻的空氣流入配置於第2熱交換器11b之下游側並作為凝結器發揮功能的第3熱交換器11c。 Therefore, when the second operation mode is executed, the air temperature is lowered by the desorption reaction of the moisture adsorption means 16, and the air cooled by the second heat exchanger 11b functioning as an evaporator flows into the second heat. The third heat exchanger 11c functions as a condenser on the downstream side of the exchanger 11b.

藉此,第3熱交換器11c之凝結溫度降低,而冷凍循環變成高效率,可使除濕裝置300之除濕容量增加。 Thereby, the condensation temperature of the third heat exchanger 11c is lowered, and the refrigeration cycle becomes high efficiency, and the dehumidification capacity of the dehumidification apparatus 300 can be increased.

又,在執行第2運轉模式時,第1熱交換器11a作為凝結器發揮功能,將流入水分吸附手段16之空氣加熱,而使相對濕度降低。藉此,可使藉水分吸附手段16之脫附反應的放濕量增加,並對作為蒸發器發揮功能的第2熱交換器11b,供給相對濕度高且焓比吸入空氣更高之狀態的空氣,可使除濕量增加。 Further, when the second operation mode is executed, the first heat exchanger 11a functions as a condenser, and heats the air flowing into the moisture adsorption means 16 to lower the relative humidity. In this way, the amount of moisture released by the desorption reaction of the moisture adsorption means 16 can be increased, and the second heat exchanger 11b functioning as an evaporator can supply air having a relatively high relative humidity and a state in which helium is higher than the intake air. Can increase the amount of dehumidification.

Further, in the heat radiating unit 200, the temperature and humidity sensor 1e, the wind speed sensor 2 separately provided to the wind speed sensor 2 of the dehumidifying unit 100, and the upstream side of the air flow direction in which the third heat exchanger 11c is detected are provided.

第6圖係表示第2實施形態的除濕裝置300之在各模式之溫濕度轉移的濕空氣線圖。此外,第6圖(a)係在第1運轉模式的濕空氣線圖,第6圖(b)係在第2運轉模式的濕空氣線圖。 Fig. 6 is a wet air diagram showing the temperature and humidity shift of each mode of the dehumidifying apparatus 300 of the second embodiment. In addition, Fig. 6(a) is a wet air diagram in the first operation mode, and Fig. 6(b) is a wet air diagram in the second operation mode.

又,第6圖(a)中之(1-1a)~(1-4a)、(1-1b)及(1-2b)係表示在第1運轉模式之通過第1熱交換器11a之前的空氣(1-1a)、通過第1熱交換器11a後的空氣(1-2a)、通過水分吸附手段16後的空氣(1-3a)、通過第2熱交換器11b後的空氣(1-4a)、通過第3熱交換器11c之前的空氣(1-1b)及通過第3熱交換器11c後的空氣(1-2b)。 Further, (1-1a) to (1-4a), (1-1b), and (1-2b) in Fig. 6(a) indicate before the first heat exchanger 11a passes through the first operation mode.

又,第6圖(b)中之(2-1a)~(2-4a)、(2-1b)及(2-2b)係表示在第2運轉模式之通過第1熱交換器11a之前的空氣(2-1a)、通過第1熱交換器11a後的空氣(2-2a)、通過水分吸附手段16後的空氣(2-3a)、通過第2熱交換器11b後的空氣(2-4a)、通過第3熱交換器11c之前的空氣(2-1b)及通過第3熱交換器11c後的空氣(2-2b)。 Further, (2-1a) to (2-4a), (2-1b), and (2-2b) in Fig. 6(b) show before the first heat exchanger 11a passes through the second operation mode.

(第1運轉模式之濕空氣線圖:除濕單元100) (wet air line diagram in the first operation mode: dehumidifying unit 100)

在第1運轉模式時的除濕單元100,自吸入口被取入第1風路50的空氣(1-1a)係被送入第1熱交換器11a。 In the dehumidifying unit 100 in the first operation mode, the air (1-1a) taken into the first air passage 50 from the suction port is sent to the first heat exchanger 11a.

在此,被取入第1風路50的空氣係藉作用為蒸發器之第1熱交換器11a所冷卻。在通過空氣被冷卻至露點溫度以下的情況,成為水分被除濕的除濕空氣(1-2a)後,被送入水分吸附手段16。 Here, the air taken into the first air passage 50 is cooled by the first heat exchanger 11a functioning as an evaporator. When the air is cooled to a temperature equal to or lower than the dew point temperature, the dehumidified air (1-2a) in which the moisture is dehumidified is sent to the moisture adsorbing means 16.

因為冷卻除濕後之空氣的相對濕度係高達約70~90%RH,所以水分吸附手段16的吸附劑易吸附水分。冷卻後的空氣被水分吸附手段16之吸附劑吸附水分而除濕後,變成高溫低濕,並流入第2熱交換器11b(1-3a)。 Since the relative humidity of the air after cooling and dehumidification is as high as about 70 to 90% RH, the adsorbent of the moisture adsorbing means 16 easily adsorbs moisture. The air after cooling is dehumidified by the adsorbent of the moisture adsorbing means 16 and dehumidified, and then becomes high temperature and low humidity, and flows into the second heat exchanger 11b (1-3a).

因為第2熱交換器11b係作為凝結器發揮功能,所以通過第2熱交換器11b之空氣被加熱,而溫度上升(1-4a)。 Since the second heat exchanger 11b functions as a condenser, the air passing through the second heat exchanger 11b is heated, and the temperature rises (1-4a).

通過第2熱交換器11b後的空氣係自空氣排出口被排出至空調對象空間。 The air that has passed through the second heat exchanger 11b is discharged from the air discharge port to the air-conditioned space.

(第1運轉模式之濕空氣線圖:散熱單元200) (wet air line diagram in the first operation mode: heat dissipation unit 200)

在第1運轉模式時的散熱單元200,自吸入口被取入第2風路51的空氣(1-1b)係被送入第3熱交換器11c。 In the heat dissipation unit 200 in the first operation mode, the air (1-1b) taken into the second air passage 51 from the suction port is sent to the third heat exchanger 11c.

在此,因為第3熱交換器11c係作為凝結器發揮功能,所以通過第3熱交換器11c後之空氣的溫度上升(1-2b)。 Here, since the third heat exchanger 11c functions as a condenser, the temperature of the air passing through the third heat exchanger 11c rises (1-2b).

通過第3熱交換器11c後的空氣係自散熱單元200的空氣排出口被排出。 The air that has passed through the third heat exchanger 11c is discharged from the air discharge port of the heat radiating unit 200.

(第2運轉模式之濕空氣線圖:除濕單元100) (wet air line diagram in the second operation mode: dehumidifying unit 100)

在第2運轉模式時的除濕單元100,自吸入口被取入第2風路51的空氣(2-1a)係被送入第1熱交換器11a。 In the dehumidifying unit 100 in the second operation mode, the air (2-1a) taken into the second air passage 51 from the suction port is sent to the first heat exchanger 11a.

在此,被取入第2風路51的空氣係藉作用為凝結器之第1熱交換器11a所加熱,而通過之空氣的溫度上升(2-2a)後,被 送入水分吸附手段16。 Here, the air taken in the second air passage 51 is heated by the first heat exchanger 11a serving as a condenser, and the temperature of the air passing therethrough is increased (2-2a). The moisture adsorption means 16 is sent.

因為加熱後之空氣的相對濕度係變成比流入空氣低,所以藉水分吸附手段16的吸附劑易脫附水分。加熱後之空氣被水分吸附手段16的吸附劑脫附水分並加濕,變成低溫高濕,並流入第2熱交換器11b(2-3a)。 Since the relative humidity of the heated air becomes lower than that of the inflowing air, the adsorbent by the moisture adsorbing means 16 tends to desorb moisture. The heated air is desorbed by the adsorbent of the moisture adsorbing means 16 and humidified to become low temperature and high humidity, and flows into the second heat exchanger 11b (2-3a).

因為第2熱交換器11b係作為蒸發器發揮功能冷卻通過空氣,所以通過第2熱交換器11b之冷卻後的空氣係被冷卻至露點溫度以下,而成為除濕空氣(2-4a)。 Since the second heat exchanger 11b functions as an evaporator to cool the passing air, the air cooled by the second heat exchanger 11b is cooled to a temperature equal to or lower than the dew point temperature to become dehumidified air (2-4a).

通過第2熱交換器11b後的空氣係自空氣排出口被排出至空調對象空間。 The air that has passed through the second heat exchanger 11b is discharged from the air discharge port to the air-conditioned space.

(第2運轉模式之濕空氣線圖:散熱單元200) (wet air line diagram in the second operation mode: heat dissipation unit 200)

在第2運轉模式時的散熱單元200,自吸入口被取入第2風路51的空氣(2-1b)係被送入第3熱交換器11c。 In the heat dissipation unit 200 in the second operation mode, the air (2-1b) taken into the second air passage 51 from the suction port is sent to the third heat exchanger 11c.

因為第3熱交換器11c係作為凝結器發揮功能,所以通過第3熱交換器11c後之空氣的溫度上升(2-2b)。 Since the third heat exchanger 11c functions as a condenser, the temperature of the air passing through the third heat exchanger 11c rises (2-2b).

通過第3熱交換器11c後的空氣係自散熱單元200的空氣排出口被排出。 The air that has passed through the third heat exchanger 11c is discharged from the air discharge port of the heat radiating unit 200.

[本第2實施形態之除濕裝置300所具有的效果] [Effects of the dehumidifier 300 of the second embodiment]

在以往之需要冷卻與除濕的空間(例如穀倉等),設置再熱除濕機及冷氣裝置,一面抑制除濕對象空間之溫升一面除濕,但是節能性減少了設置再熱除濕機及冷氣裝置之2台裝置的量。 In the space where cooling and dehumidification are required in the past (for example, a barn, etc.), a reheat dehumidifier and a cooling device are provided, and the dehumidification of the dehumidification space is suppressed while the dehumidification is performed, but the energy saving property is reduced by the reheat dehumidifier and the air conditioner. The amount of the device.

可是,因為本第2實施形態之除濕裝置300係將凝結熱排出至除濕對象外,所以可抑制除濕對象空間之溫升,或可冷卻,而可抑制節能性降低。 However, since the dehumidifying apparatus 300 of the second embodiment discharges the heat of condensation to the object to be dehumidified, it is possible to suppress the temperature rise of the space to be dehumidified or to cool, and it is possible to suppress a decrease in energy saving performance.

本第2實施形態之除濕裝置300係藉由控制第2送風手段12b的轉速,來調整在散熱單元200流動的風速,因為可控制除濕單元100的除濕量,所以可易於達成因應於目的的除濕量。 The dehumidifier 300 of the second embodiment adjusts the wind speed flowing through the heat radiating unit 200 by controlling the number of revolutions of the second air blowing means 12b. Since the dehumidifying amount of the dehumidifying unit 100 can be controlled, it is easy to achieve dehumidification according to the purpose. the amount.

此外,本第2實施形態之除濕裝置300亦可應用在第1實施形態所說明的變形例。 Further, the dehumidifying apparatus 300 according to the second embodiment can be applied to the modification described in the first embodiment.

在本第3實施形態,主要說明與第1、第2實施形態的相異點,關於共同部分省略說明。 In the third embodiment, differences from the first and second embodiments will be mainly described, and the description of the common portions will be omitted.

第3實施形態之除濕裝置300係在第1、第2實施形態的第3熱交換器11c與四通閥15之間新設置第2節流手段14a。 In the dehumidifier 300 of the third embodiment, the second throttle means 14a is newly provided between the third heat exchanger 11c and the four-way valve 15 of the first and second embodiments.

此外,在本第3實施形態,將在第1、第2實施形態的第2熱交換器11b與第1熱交換器11a之間的節流手段14稱為第1節流手段14b。 In the third embodiment, the throttle means 14 between the second heat exchanger 11b and the first heat exchanger 11a of the first and second embodiments is referred to as a first throttle means 14b.

從壓縮機13所排出的冷媒係向第3熱交換器11c流動。在此時,第3熱交換器11c係作用為凝結器,冷媒係在與空氣進行熱交換時一部分凝結成液體。在通過第3熱交換器11c後,冷媒係在第2節流手段14a降壓後,通過四通閥15,向第2熱交換器11b流動。第2熱交換器11b係作用為凝結器,冷媒係在與空氣進行熱交換時凝結成液體後,向第1節流手段14b流動。冷媒係在第1節流手段14b被降壓後,流至第1熱交換器11a。第1熱交換器11a係作為蒸發器發揮功能,冷媒係在與空氣進行熱交換而蒸發後,通過四通閥15,再被壓縮機13吸入。 The refrigerant discharged from the compressor 13 flows into the third heat exchanger 11c. At this time, the third heat exchanger 11c functions as a condenser, and the refrigerant partially condenses into a liquid when it exchanges heat with air. After passing through the third heat exchanger 11c, the refrigerant is depressurized by the second throttle means 14a, and then flows through the four-way valve 15 to the second heat exchanger 11b. The second heat exchanger 11b functions as a condenser, and the refrigerant condenses into a liquid when it exchanges heat with air, and then flows to the first throttle means 14b. The refrigerant is depressurized by the first throttle means 14b, and then flows to the first heat exchanger 11a. The first heat exchanger 11a functions as an evaporator, and the refrigerant evaporates by exchanging heat with air, passes through the four-way valve 15, and is sucked by the compressor 13.

(第2運轉模式之冷媒的流動) (Flow of refrigerant in the second operation mode)

參照第7圖及第8圖,說明在第2運轉模式之冷媒的流動。 The flow of the refrigerant in the second operation mode will be described with reference to Figs. 7 and 8.

從壓縮機13所排出的冷媒係向第3熱交換器11c流動。在此時,第3熱交換器11c係作用為凝結器,冷媒係在與空氣進行熱交換時一部分凝結成液體。在通過第3熱交換器11c後,冷媒係在第2節流手段14a被降壓後,通過四通閥15,向第1熱交換器11a流動。第1熱交換器11a係作用為凝結器,冷媒係在與空氣進行熱交換時凝結成液體後,向第1節流手段14b流動。冷媒係在第1節流手段14b被降壓後,流至第2熱交換器11b。第2熱交換器11b係作為蒸發器發揮功能,冷媒係在與空氣進行熱交換而蒸發後,通過四通閥15,再被壓縮機13吸入。 The refrigerant discharged from the compressor 13 flows into the third heat exchanger 11c. At this time, the third heat exchanger 11c functions as a condenser, and the refrigerant partially condenses into a liquid when it exchanges heat with air. After passing through the third heat exchanger 11c, the refrigerant is depressurized by the second throttle means 14a, and then flows through the four-way valve 15 to the first heat exchanger 11a. The first heat exchanger 11a functions as a condenser, and the refrigerant condenses into a liquid when it exchanges heat with air, and then flows to the first throttle means 14b. The refrigerant is depressurized by the first throttle means 14b, and then flows to the second heat exchanger 11b. The second heat exchanger 11b functions as an evaporator, and the refrigerant is evaporated by heat exchange with air, and then passed through the four-way valve 15 and sucked by the compressor 13.

[本第3實施形態之除濕裝置300所具有的效果] [Effects of the dehumidifying apparatus 300 of the third embodiment]

本第3實施形態之除濕裝置300係除了第1實施形態之除濕裝置300所具有的效果以外,還具有如下之效果。 In addition to the effects of the dehumidifying apparatus 300 of the first embodiment, the dehumidifying apparatus 300 of the third embodiment has the following effects.

藉由調整第2節流手段14a的孔口,可控制第3熱交換器11c的凝結熱量,不必變更熱交換器11的導熱面積,就可實現配合流入空氣之溫度及濕度的運轉狀態。 By adjusting the orifice of the second throttle means 14a, the heat of condensation of the third heat exchanger 11c can be controlled, and the operating state of the temperature and humidity of the inflowing air can be realized without changing the heat transfer area of the heat exchanger 11.

例如,在濕度比第1值低的低濕空氣(例如溫度26℃、濕度40%),藉由使第2節流手段14a的孔口變小,在第2運轉模式時使第3熱交換器11c的凝結壓力上升,而使凝結熱量增加,第1熱交換器11a之凝結熱量降低,藉此,可避免對流入水分吸附手段16之空氣過度加熱。 For example, in the low-humidity air (for example, the temperature of 26 ° C and the humidity of 40%) whose humidity is lower than the first value, the third heat exchange is performed in the second operation mode by reducing the orifice of the second throttle means 14a. The condensation pressure of the device 11c rises, and the heat of condensation increases, and the heat of condensation of the first heat exchanger 11a is lowered, whereby excessive heating of the air flowing into the moisture adsorbing means 16 can be avoided.

反之,在濕度比第2值高的高濕空氣(例如溫度26℃、濕度80%),藉由使第2節流手段14a的孔口變大,在第2運轉模式時使第3熱交換器11c的凝結壓力降低,而使凝結熱量減少,第1熱交換器11a之凝結熱量增加,藉此,可使流入水分吸附手段16之空氣的相對濕度降低,使放濕量增加。 On the other hand, in the high-humidity air (for example, the temperature of 26 ° C and the humidity of 80%) whose humidity is higher than the second value, the third heat exchange is performed in the second operation mode by increasing the orifice of the second throttle means 14a. The condensation pressure of the device 11c is lowered, and the amount of heat of condensation is reduced, and the amount of heat of condensation in the first heat exchanger 11a is increased, whereby the relative humidity of the air flowing into the moisture adsorbing means 16 can be lowered to increase the amount of moisture released.

此外,在上述,說明是(1)第2值比第1值大、(2)第1值是比40大且比80小的值、(3)第2值是比80小且比40大的值之情況的例子,但是未限定如此,亦可因應於除濕對象空間之溫度等來變更。 In addition, in the above description, (1) the second value is larger than the first value, (2) the first value is larger than 40 and smaller than 80, and (3) the second value is smaller than 80 and larger than 40. An example of the case of the value is not limited thereto, and may be changed depending on the temperature of the dehumidification target space or the like.

In the fourth embodiment, differences from the first to third embodiments will be mainly described, and the description of the common portions will be omitted.

在本第4實施形態,第1熱交換器11a與第2熱 交換器11b並聯。又,與第1~第3實施形態相異,拆下四通閥15。又,第3熱交換器11c的下游側係與第1熱交換器11a及第2熱交換器11b的上游側連接。進而,替代第1~第2實施形態的節流手段14及第3實施形態的第2節流手段14a與第1節流手段14b,設置第3節流手段14c與第4節流手段14d。 In the fourth embodiment, the first heat exchanger 11a and the second heat The exchangers 11b are connected in parallel. Further, unlike the first to third embodiments, the four-way valve 15 is removed. Further, the downstream side of the third heat exchanger 11c is connected to the upstream side of the first heat exchanger 11a and the second heat exchanger 11b. Further, the third throttle means 14c and the fourth throttle means 14d are provided instead of the throttle means 14 of the first to second embodiments and the second throttle means 14a and the first throttle means 14b of the third embodiment.

Further, in the second operation mode, the third throttle means 14c is fully closed.

[說明濕空氣線圖] [Description of wet air line diagram]

第10圖係表示第4實施形態的除濕裝置300之在各模式之溫濕度轉移的濕空氣線圖。此外,第10圖(a)係在第1運轉模式的濕空氣線圖,第10圖(b)係在第2運轉模式的濕空氣線圖。 Fig. 10 is a wet air diagram showing the temperature and humidity shift of each mode of the dehumidifying apparatus 300 of the fourth embodiment. Further, Fig. 10(a) is a wet air diagram in the first operation mode, and Fig. 10(b) is a wet air diagram in the second operation mode.

又,第10圖(a)中之(1-1c)~(1-5c)係表示在第1運轉模式之通過第1熱交換器11a之前的空氣(1-1c)、通過第1熱交換器11a後的空氣(1-2c)、通過水分吸附手段16後的空氣(1-3c)、通過第2熱交換器11b後的空氣(1-4c)、通過第3熱交換器11c後的空氣(1-5c)。 Further, (1-1c) to (1-5c) in Fig. 10(a) show the air (1-1c) before passing through the first heat exchanger 11a in the first operation mode, and the first heat exchange is performed. Air (1-2c) after the device 11a, air (1-3c) after passing through the moisture adsorbing means 16, air (1-4c) after passing through the second heat exchanger 11b, and after passing through the third heat exchanger 11c Air (1-5c).

又,第10圖(b)中之(2-1c)~(2-5c)係表示在第2運轉模式之通過第1熱交換器11a之前的空氣(2-1c)、通過第1熱交 換器11a後的空氣(2-2c)、通過水分吸附手段16後的空氣(2-3c)、通過第2熱交換器11b後的空氣(2-4c)、通過第3熱交換器11c後之空氣(2-5c)的狀態。 Further, (2-1c) to (2-5c) in Fig. 10(b) show the air (2-1c) before passing through the first heat exchanger 11a in the second operation mode, and the first heat is passed. Air (2-2c) after the inverter 11a, air (2-3c) after passing through the moisture adsorbing means 16, air (2-4c) after passing through the second heat exchanger 11b, and after passing through the third heat exchanger 11c The state of the air (2-5c).

參照第10圖,說明在第1運轉模式及第2運轉模式之空氣的狀態。 The state of the air in the first operation mode and the second operation mode will be described with reference to Fig. 10 .

此外,在第10圖(a),表示水分吸附手段16之水分保持量變少,而對高濕之空氣(例如相對濕度70%以上)進行吸附反應之情況的例子。又,在第10圖(b),表示水分吸附手段16之水分保持量變多,而對低濕之空氣(例如相對濕度60%以下)進行脫附反應之情況的例子。 In addition, (a) of FIG. 10 shows an example in which the moisture retention amount of the moisture adsorbing means 16 is small, and the high-humidity air (for example, a relative humidity of 70% or more) is subjected to an adsorption reaction. In addition, in the figure (b) of FIG. 10, an example in which the moisture retention amount of the moisture adsorbing means 16 is increased and the dehumidification reaction is performed on low-humidity air (for example, a relative humidity of 60% or less) is shown.

(第1運轉模式之濕空氣線圖) (wet air line diagram in the first operation mode)

在第1運轉模式,自吸入口被取入風路內的空氣(1-1c)係被送入第1熱交換器11a。 In the first operation mode, the air (1-1c) taken into the air passage from the suction port is sent to the first heat exchanger 11a.

在此,被取入風路內的空氣係藉作用為蒸發器之第1熱交換器11a所冷卻,在通過空氣被冷卻至露點溫度以下的情況,成為水分被除濕的除濕空氣(1-2c)後,被送入水分吸附手段16。 Here, the air taken into the air passage is cooled by the first heat exchanger 11a serving as the evaporator, and when it is cooled to a temperature equal to or lower than the dew point by the air, the dehumidified air is dehumidified (1-2c). After that, it is sent to the moisture adsorption means 16.

因為冷卻除濕後之空氣的相對濕度係高達約70~90%RH,所以水分吸附手段16的吸附劑易吸附水分。冷卻後的空氣被水分吸附手段16之吸附劑吸附水分而除濕後,變成高溫低濕,並流入第2熱交換器11b(1-3c)。 Since the relative humidity of the air after cooling and dehumidification is as high as about 70 to 90% RH, the adsorbent of the moisture adsorbing means 16 easily adsorbs moisture. The air after cooling is desorbed by the adsorbent of the moisture adsorbing means 16 and dehumidified, and then becomes high temperature and low humidity, and flows into the second heat exchanger 11b (1-3c).

第2熱交換器11b係因為第4節流手段14d全閉,所以不會作為熱交換器發揮功能,而不發生溫濕度變化(1-4c)。通過第2熱交換器11b後的空氣係流入第3熱交換器11c(1-4c)。 Since the fourth heat exchanger 11b is fully closed, the fourth throttle means 14b does not function as a heat exchanger, and does not cause temperature and humidity changes (1-4c). The air that has passed through the second heat exchanger 11b flows into the third heat exchanger 11c (1-4c).

因為第3熱交換器11c係作為凝結器發揮功能,所以使通過空氣的溫度上升,並自空氣的排出口被排出至除濕對象空間(1-5c)。 Since the third heat exchanger 11c functions as a condenser, the temperature of the passing air rises and is discharged from the air discharge port to the dehumidification target space (1-5c).

(第2運轉模式之濕空氣線圖) (wet air line diagram in the second operation mode)

在第2運轉模式時,自吸入口被取入風路內的空氣(2-1c)係被送入第1熱交換器11a。 In the second operation mode, the air (2-1c) taken into the air passage from the suction port is sent to the first heat exchanger 11a.

在此,第1熱交換器11a係因為第3節流手段14c是全閉,所以不會作為熱交換器發揮功能,而不發生溫濕度變化(2-2c),並被送入水分吸附手段16。 In the first heat exchanger 11a, since the third throttle means 14c is fully closed, it does not function as a heat exchanger, and does not change in temperature and humidity (2-2c), and is sent to the moisture adsorption means. 16.

因應於流入空氣的相對濕度,水分吸附手段16的吸附劑易脫附水分。流入空氣被水分吸附手段16的吸附劑脫附水分並加濕,變成低溫高濕,並流入第2熱交換器11b(2-3c)。 The adsorbent of the moisture adsorbing means 16 easily desorbs moisture in response to the relative humidity of the inflowing air. The inflowing air is desorbed by the adsorbent of the moisture adsorbing means 16 and humidified to become low temperature and high humidity, and flows into the second heat exchanger 11b (2-3c).

因為第2熱交換器11b係作為蒸發器發揮功能,所以冷卻通過空氣,而在冷卻後之通過空氣的溫度被冷卻至露點溫度以下的情況,成為水分被除濕的除濕空氣(2-4c)。 Since the second heat exchanger 11b functions as an evaporator, the air is cooled and passed through the air, and the temperature of the passing air after cooling is cooled to a temperature equal to or lower than the dew point temperature, and the dehumidified air (2-4c) is dehumidified.

因為第3熱交換器11c係作為凝結器發揮功能,所以使通過空氣的溫度上升,並自空氣的排出口被排出至除濕對象空間(2-5c)。 Since the third heat exchanger 11c functions as a condenser, the temperature of the passing air rises and is discharged from the air discharge port to the dehumidification target space (2-5c).

[本第4實施形態之除濕裝置300所具有的效果] [Effects of the dehumidifying apparatus 300 of the fourth embodiment]

本第4實施形態之除濕裝置300係除了第1實施形態之除濕裝置300所具有的效果以外,還具有如下之效果。 In addition to the effects of the dehumidifying apparatus 300 of the first embodiment, the dehumidifying apparatus 300 of the fourth embodiment has the following effects.

本第4實施形態之除濕裝置300係對低濕的空氣(例如溫度26℃、濕度30%),可抑制在第2運轉模式時流入水分吸附手段16之空氣的過加熱。 The dehumidifying apparatus 300 according to the fourth embodiment is capable of suppressing overheating of the air flowing into the moisture adsorbing means 16 in the second operational mode in the case of low-humidity air (for example, a temperature of 26 ° C and a humidity of 30%).

又,可減少在第1運轉模式與第2運轉模式之間之模式切換時的切換損失(從凝結器切換成蒸發器時之熱交換器的熱容量等),使除濕量增加。 Further, it is possible to reduce the switching loss (the heat capacity of the heat exchanger when switching from the condenser to the evaporator) between the first operation mode and the second operation mode, and to increase the amount of dehumidification.

此外,本第4實施形態之除濕裝置300亦可應用在第1實施形態所說明之變形例。 Further, the dehumidifying apparatus 300 of the fourth embodiment can be applied to the modification described in the first embodiment.
