In addition, the external air is heated by a regenerative heater, and the moisture absorbed by the dehumidifying rotor is removed through the regeneration zone of the dehumidifying rotor, thereby preventing frosting of the evaporator and achieving dehumidifying performance.
Description
本發明係有關於一種例如用於冷藏倉庫或者冷凍倉庫等的除濕裝置。 The present invention relates to a dehumidifier for use in, for example, a refrigerated warehouse or a freezer warehouse.
冷藏倉庫、冷凍倉庫或者冰箱、冰櫃一般情況下利用使用了氟氯昂的冷凍迴圈，用於冷藏倉庫的冷凍迴圈中，最近利用的是一部分使用了氨氣的冷凍迴圈。 Refrigerated warehouses, freezers, or refrigerators and freezers generally use frozen loops that use chlorofluorocarbons. They are used in the frozen loops of refrigerated warehouses. Recently, some of the freeze loops using ammonia have been used.
當冷藏倉庫內的溫度比外部氣體的露點低時，運行中的蒸發器(evaporator)上結霜。如果結霜，則熱交換效率降低，嚴重的情況下，有時蒸發器的熱交換器會完全被霜堵塞，導致空氣不能流通。 When the temperature in the refrigerated warehouse is lower than the dew point of the outside air, frost is formed on the evaporator in operation. If it is frosted, the heat exchange efficiency is reduced. In severe cases, the heat exchanger of the evaporator may be completely blocked by the frost, and air may not flow.
因此，按特定的週期停止冷凍機的運行，使暖風向蒸發器上流通，來使霜融化。 Therefore, the operation of the freezer is stopped at a specific cycle, and warm air is circulated to the evaporator to melt the frost.
這樣，由於在霜的解凍中冷凍機停止運行，因此，保管冷凍食品等冷凍機停止運行時保存物品的品質降低的物品的冷藏倉庫的情況下存在問題。 In this way, since the freezer is stopped during the defrosting of the frost, there is a problem in the case of a refrigerated warehouse that stores items with reduced quality when the freezer such as frozen food is stopped.
因此，存在如下冷凍機，即，在一台冷凍機上設置兩台蒸發器，使兩台蒸發器交替運行，從而交替將霜融化。這類冷凍機雖然能夠在不停止冷凍機的情況下消除霜，但是，由於設置兩台蒸發器，因此存在增加成本並且需要設置兩台蒸 發器的空間的問題。 Therefore, there is a refrigerator in which two evaporators are provided on one refrigerator, and the two evaporators are alternately operated, thereby melting frost alternately. Although this type of freezer can eliminate frost without stopping the freezer, because two evaporators are installed, there is an increase in cost and two steam generators are required. Hair space issue.
所謂蒸發器上結霜是指，冷凍機上有潛熱負荷，會浪費能源。即，為了產生霜，在蒸發器上產生水的冷凝熱和凍結熱。在日本的氣象條件下，通常該潛熱負荷在冷凍機的消耗能源中占接近一半。而且，由於霜的熱傳導率低，因此存在蒸發器的熱交換率不良的問題。 The so-called frost on the evaporator refers to the latent heat load on the freezer, which will waste energy. That is, in order to generate frost, heat of condensation and freezing of water is generated on the evaporator. Under Japanese meteorological conditions, the latent heat load usually accounts for nearly half of the energy consumed by the refrigerator. Furthermore, since the thermal conductivity of frost is low, there is a problem that the heat exchange rate of the evaporator is poor.
作為防止空氣中的水分在該蒸發器中結霜的技術，發明了如專利文獻1中公開的技術那樣的除濕裝置，該除濕裝置利用除濕轉子(desiccant rotor)吸附空氣中的水分，並將冷凍機的廢熱作為水分脫附的熱源，從而減少能源消耗。 As a technology for preventing the moisture in the air from frosting in the evaporator, a dehumidification device such as the technology disclosed in Patent Document 1 is invented. The dehumidification device uses a desiccant rotor to adsorb moisture in the air and freezes the moisture. The machine's waste heat acts as a heat source for moisture desorption, thereby reducing energy consumption.
另外，專利文獻2公開的是與專利文獻1同樣地防止空氣中的水分在蒸發器中結霜的技術，其提供如下除濕裝置，即，使用吸附水分的轉子，調整吸附水分的轉子的吸附劑的細孔徑，從而不使細孔內的水分凍結。 In addition, Patent Document 2 discloses a technology that prevents moisture in the air from being frosted in the evaporator in the same manner as in Patent Document 1. It provides a dehumidifier that uses a rotor that adsorbs moisture and adjusts the adsorbent of the rotor that adsorbs moisture. The pore diameter of the pores is not frozen.
專利文獻1：日本特開2001-179036號公報； 專利文獻2：WO2008-084573號公報。 Patent Document 1: Japanese Patent Laid-Open No. 2001-179036; Patent document 2: WO2008-084573.
專利文獻1中公開的是能夠利用除濕轉子吸附進入蒸發器前的空氣中的水分來抑制蒸發器上結霜的技術，但是對除濕轉子的凍結沒有提及，也沒有公開有關送風機的耐低溫性的技術。 Patent Document 1 discloses a technology capable of suppressing frost on the evaporator by using a dehumidifying rotor to adsorb moisture in the air before entering the evaporator, but does not mention freezing of the dehumidifying rotor and does not disclose the low temperature resistance of the blower. Technology.
專利文獻2中沒有公開使用未調整水分吸附轉子 的吸附劑細孔徑的除濕轉子的技術。另外，也沒有公開關於送風機的耐低溫性的技術。 Patent Document 2 does not disclose the use of an unadjusted moisture adsorption rotor The technology of dehumidifier rotor with fine pores of adsorbent. In addition, there is no technology disclosed about the low temperature resistance of the blower.
即，兩個專利文獻都沒有公開不管使用什麼樣的除濕轉子都不會使轉子本身凍結地能夠用於冷藏倉庫或者冷凍倉庫且能源消耗低的除濕裝置。 That is, neither of the two patent documents discloses a dehumidifier having a low energy consumption that can be used in a refrigerated warehouse or a refrigerated warehouse without freezing the rotor itself, regardless of the type of dehumidifying rotor used.
本發明用於解決如上所述的問題，其最重要的特徵在於：將除濕轉子的淨化空氣全部返回到除濕機處理入口，以使從冷藏倉庫或者冷凍倉庫流出的空氣能夠全部迴圈。 The present invention is used to solve the problems described above, and its most important feature is that all the purified air of the dehumidification rotor is returned to the dehumidifier processing inlet so that all the air flowing from the refrigerated warehouse or the frozen warehouse can be looped.
由於本發明的除濕裝置具有如上結構，因此能夠提供如下除濕裝置，即，由於使冷藏倉庫內的空氣通過除濕轉子的處理(吸附)區後全部返回到冷藏倉庫，從而不僅達到節省能源，還能夠防止蒸發器的結霜。 Since the dehumidifying device of the present invention has the above structure, it is possible to provide a dehumidifying device that allows air in the refrigerated warehouse to pass through the processing (adsorption) area of the dehumidifying rotor and returns to the refrigerated warehouse, thereby saving energy and enabling Prevent frost on the evaporator.
另外，由於使通過了除濕轉子的淨化區(purge zone)的空氣返回到處理送風機的前面，因此，使來自倉庫行業法施工條例所規定的冷藏室的保管溫度區間“C1級”(攝氏零下10度以下且攝氏零下20度以上)以下的冷藏倉庫的被處理空氣溫度上升，使得不會變為處理送風機不能使用的溫度以下，也不會使除濕轉子凍結。 In addition, since the air that has passed through the purge zone of the dehumidifying rotor is returned to the front of the processing blower, the storage temperature zone "C1" (minus 10 degrees Celsius) from the refrigerating compartment specified in the Construction Regulations of the Warehouse Industry Law is returned. The temperature of the processed air in the refrigerated warehouse is lower than the temperature and the temperature is lower than -20 degrees Celsius), so that the temperature of the processed air does not become lower than the temperature at which the processing fan cannot be used, and the dehumidifying rotor is not frozen.

使來自冷藏倉庫的處理空氣通過用於與除濕轉子的處理出口空氣進行熱交換的顯熱交換器，並使其通過分割成處理區、再生區、淨化區這三個區的除濕轉子的處理區和淨化區(purge zone)，使通過了淨化區的空氣返回處理空氣中，使從處理區流出的處理出口空氣在上述顯熱交換器中與處理空氣進行熱交換之後供給至冷藏倉庫。另外，能夠提供一種除濕裝置，該除濕裝置通過再生加熱器將外部空氣進行加熱，並使其通過除濕轉子的再生區來將除濕轉子吸附的水分脫落後向外排氣，從而能夠防止蒸發器結霜。 The processing air from the refrigerated warehouse is passed through a sensible heat exchanger for heat exchange with the processing outlet air of the dehumidification rotor, and passed through the processing area of the dehumidification rotor divided into three areas: a processing area, a regeneration area, and a purification area. And a purge zone, returning the air that has passed through the purge zone to the process air, and allowing the process outlet air flowing out of the process zone to exchange heat with the process air in the sensible heat exchanger, and then supply the refrigerated warehouse. In addition, it is possible to provide a dehumidifier that heats the outside air through a regenerative heater and causes it to pass through the regeneration zone of the dehumidifier rotor to remove the moisture absorbed by the dehumidifier rotor and exhaust it to the outside, thereby preventing the evaporator from freezing. Frost.
實施例1 Example 1
以下採用附圖，對本發明的冷藏倉庫用除濕裝置的實施例進行詳細說明。圖1是表示本發明實施例1的除濕裝置的空氣流動的流動圖。 Hereinafter, embodiments of the dehumidifier for a refrigerated warehouse according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a flow chart showing the flow of air in a dehumidifier according to Embodiment 1 of the present invention.
圖1中的1是除濕轉子，分割成三個區，分別為處理區2、淨化區3和再生區4。在除濕轉子1的旋轉方向，依次為處理區2、再生區4、淨化區3。該除濕轉子1通過電機(未圖示)來旋轉。 1 in FIG. 1 is a dehumidifying rotor, which is divided into three zones, namely a processing zone 2, a purification zone 3, and a regeneration zone 4. In the rotation direction of the dehumidification rotor 1, it is a processing zone 2, a regeneration zone 4, and a purification zone 3 in this order. The dehumidifying rotor 1 is rotated by a motor (not shown).
利用處理送風機11使冷藏倉庫5內的處理空氣通過正交顯熱交換器12，再通過除濕轉子1的處理區2而成為乾燥空氣，並在正交顯熱交換器12中與處理空氣進行熱交換之後返回到冷藏倉庫5內。 The processing air blower 11 passes the processing air in the refrigerated warehouse 5 through the orthogonal display heat exchanger 12 and then passes through the processing area 2 of the dehumidifying rotor 1 to become dry air, and heats the processing air in the orthogonal display heat exchanger 12 with the processing air. After the exchange, it is returned to the refrigerated warehouse 5.
從處理送風機11流出的空氣的一部分通過除濕轉子1的淨化區3後，與從正交顯熱交換器12流出的處理空氣混合。 Part of the air flowing out of the processing blower 11 passes through the purification zone 3 of the dehumidifying rotor 1 and is mixed with the processing air flowing out of the orthogonal display heat exchanger 12.
利用再生送風機10，使外部空氣OA通過再生加熱器9來被加熱，通過除濕轉子1的再生區4來脫落被除濕轉子1吸附的水分，並向外排氣。 With the regeneration blower 10, the outside air OA is heated by the regeneration heater 9, and the moisture absorbed by the dehumidification rotor 1 is shed through the regeneration zone 4 of the dehumidification rotor 1, and is exhausted to the outside.
通過上述結構，使通過淨化區被加熱的空氣返回到從冷藏倉庫流出的處理空氣中，從而不需要使用具有特殊的耐低溫性的處理送風機，能夠減少原始成本，也能夠防止除濕轉子的凍結。另外，由於將從冷藏倉庫流出的處理空氣全部返回到冷藏倉庫，因此，外部空氣不會侵入到冷藏倉庫，從而能夠節能。 With the above-mentioned structure, the air heated in the purification zone is returned to the processing air flowing from the refrigerated warehouse, thereby eliminating the need for a special low-temperature-resistant processing blower, reducing the original cost, and preventing the dehumidification rotor from freezing. In addition, since all the processing air flowing from the refrigerated warehouse is returned to the refrigerated warehouse, the outside air does not enter the refrigerated warehouse, and energy can be saved.
例如，當冷藏倉庫5內的溫度為攝氏零下30度(以下溫度都是“攝氏”)且除濕轉子的再生溫度為140度的情況下，使用熱交換率為52.4%的正交顯熱交換器12，顯熱交換器出口溫度達到零下13.2度，通過與從除濕轉子1的淨化區3流出的溫度為42度的空氣混合，空氣溫度達到零下5.4度。另外，除濕轉子1的處理區2的入口溫度為零下2.4度且露點溫度為零下30度，處理區2的出口溫度為2度且露點溫度為零下40度，在正交顯熱交換器12中與從冷藏倉庫流出的處理空氣進行熱交換，從而供給至冷藏倉庫的空氣溫度達到零下14.7度且露點溫度達到零下40度。 For example, when the temperature in the refrigerated warehouse 5 is minus 30 degrees Celsius (the following temperatures are all "Celsius") and the regeneration temperature of the dehumidifying rotor is 140 degrees, an orthogonal sensible heat exchanger with a heat exchange rate of 52.4% is used. 12. The temperature of the outlet of the sensible heat exchanger reaches minus 13.2 degrees. By mixing with 42 degrees of air flowing from the purification zone 3 of the dehumidifying rotor 1, the air temperature reaches minus 5.4 degrees. In addition, the inlet temperature of the processing zone 2 of the dehumidifying rotor 1 is minus 2.4 degrees and the dew point temperature is minus 30 degrees, and the outlet temperature of the processing zone 2 is 2 degrees and the dew point temperature is minus 40 degrees. Heat exchange is performed with the processing air flowing from the refrigerated warehouse, so that the temperature of the air supplied to the refrigerated warehouse reaches minus 14.7 degrees and the dew point temperature reaches minus 40 degrees.
實施例2 Example 2
圖2是表示本發明實施例2的除濕裝置的空氣流動的流動圖。與實施例1不同點是由於設置空間的問題等而不能設置顯熱交換器12情況下的實施例。其他的結構是共同的，因此在此省略重複說明。 Fig. 2 is a flow chart showing air flow in a dehumidifier according to a second embodiment of the present invention. The difference from the first embodiment is an embodiment in which the sensible heat exchanger 12 cannot be installed due to a problem in the installation space or the like. Since other structures are common, redundant description is omitted here.
利用處理送風機11，使冷藏倉庫5內的處理空氣通過除濕轉子1的處理區2來成為乾燥空氣，並返回到冷藏倉庫5內。從處理送風機11流出的空氣的一部分通過除濕轉子1的淨化區3後與從冷藏倉庫5流出的處理空氣混合，而為了使該空氣溫度成為處理送風機11能夠使用的溫度，通過將淨化區的區比增大等方法，使得通過淨化區的空氣的風量增多。另外，也可以在處理送風機入口處設置溫度感測器等溫度檢測裝置，並將通過閘板等風量調整裝置來調整通過處理區和淨化區的風量比。 The processing air blower 11 passes the processing air in the refrigerated warehouse 5 through the processing area 2 of the dehumidifying rotor 1 to become dry air, and returns to the refrigerated warehouse 5. Part of the air flowing out of the processing blower 11 passes through the purification zone 3 of the dehumidifying rotor 1 and is mixed with the processing air flowing out of the refrigerated warehouse 5. In order to make the air temperature reach the temperature that the processing blower 11 can use, the area of the purification zone Methods such as increasing the ratio increase the air volume of the air passing through the purification zone. In addition, a temperature detection device such as a temperature sensor may be provided at the inlet of the processing blower, and the air volume ratio passing through the processing area and the purification area may be adjusted by an air volume adjusting device such as a shutter.
一般情況下，通過淨化區的空氣的風量為通過處理區的空氣的風量的1/2~1/10為好，但是較佳為1/3~1/6。表1表示，當使用直徑為320mm、寬度為400mm的蜂巢轉輪且處理區入口溫度為零下20度、再生溫度為140度、再生空氣濕度為20g/kg、再生風量比(再生風量/處理風量)為1/6時的淨化風量對除濕性能帶來的影響的實驗結果。通過將淨化風量比(再生風量/處理風量)設為1/2~1/10，使得處理區出口的露點溫度與沒有淨化的情況相比降低了15度以上，通過設為1/3~1/6，來降低20度以上。 In general, the air volume of the air passing through the purification zone is preferably 1/2 to 1/10 of the air volume of the air passing through the processing zone, but is preferably 1/3 to 1/6. Table 1 shows that when using a honeycomb runner with a diameter of 320mm and a width of 400mm, the inlet temperature of the processing area is -20 ° C, the regeneration temperature is 140 ° C, the regeneration air humidity is 20g / kg, and the regeneration air volume ratio (regeneration air volume / processing air volume) ) Is the experimental result of the influence of the purification air volume on the dehumidification performance at 1/6. By setting the purification air volume ratio (regenerative air volume / processing air volume) to 1/2 to 1/10, the dew point temperature at the exit of the processing zone is reduced by more than 15 degrees compared to the case without purification, and by setting it to 1/3 to 1 / 6, to lower more than 20 degrees.
除濕裝置開始運行時，可以將閘閥6、7、8關閉後開始運行，使冷藏倉庫內的冰點下的低溫空氣不直接通過處理送風機，在處理送風機入口溫度充分上升後打開閘閥6、7、8。 另外，實施例1中也可以為相同的操作。另外，雖然冰點下的空氣向顯熱交換器12流動，但是由於與從冷藏倉庫5進入顯熱交換器12的溫度相比，返回到冷藏倉庫5的空氣的幹球溫度高且露點溫度低，因此在顯熱交換器12內不會產生霜。 When the dehumidification device starts to operate, the gate valves 6, 7, and 8 can be closed and started to operate, so that the low-temperature air under the freezing point in the refrigerated warehouse does not directly pass through the processing blower, and the gate valve 6, 7, 8 is opened after the processing blower inlet temperature has sufficiently increased. . The same operation can be performed in the first embodiment. In addition, although the air at the freezing point flows to the sensible heat exchanger 12, the air returned to the refrigerated warehouse 5 has a higher dry bulb temperature and a lower dew point temperature than the temperature of the refrigerated warehouse 5 entering the sensible heat exchanger 12, Therefore, no frost is generated in the sensible heat exchanger 12.
如上所述，使通過了淨化區的所有空氣與被處理空氣混合，從而使得供給至處理送風機的被處理空氣的溫度上升，因此通常使用的送風機的最低使用溫度為零下10度左右，因此不需要採用具有特殊的耐低溫性的送風機，還能夠防止除濕轉子的凍結。另外，由於從冷藏倉庫流出的被處理空氣的全部返回到冷藏倉庫，因此，不需要導入外部空氣，從而節省能源，也不需要設置外部空氣處理用的預冷器，從而還能降低原始成本。一般在市場上銷售的送風機的耐低溫性是結合日本的氣象條件而設計的。因此，屋內使用的一般的送風機的情況下，廠家保證的最低溫度為零下10度左右。本發明能夠使用這種一般的送風機，因此在成本和交貨時間上作出了貢獻。 As described above, all the air that has passed through the purification zone is mixed with the air to be processed, so that the temperature of the air to be supplied to the processing blower rises. Therefore, the minimum use temperature of the generally used blower is about minus 10 degrees. The use of blowers with special low-temperature resistance also prevents freezing of the dehumidification rotor. In addition, since all of the processed air flowing out of the refrigerated warehouse is returned to the refrigerated warehouse, there is no need to introduce external air, thereby saving energy, and no need to install a pre-cooler for external air processing, thereby reducing the original cost. The low temperature resistance of blowers generally sold in the market is designed in accordance with the weather conditions in Japan. Therefore, in the case of a general blower used indoors, the minimum temperature guaranteed by the manufacturer is about -10 degrees below zero. The present invention can use such a general blower, and thus contributes to cost and delivery time.
本發明提供了一種除濕裝置，該除濕裝置能夠防止冷藏倉庫、冷凍倉庫等的蒸發器的結霜，且降低能源消耗。 The invention provides a dehumidifying device, which can prevent frosting of evaporators in a refrigerated warehouse, a freezer warehouse, and the like, and reduce energy consumption.
