Description

本発明は、換気装置に関し、より詳細には、通常の換気除湿モードを遂行する他に、室内空気だけを除湿するために迂回流路を有し、除湿のない換気モードを遂行するために、除湿ローターを迂回する流路構造を有する換気装置に関する。   The present invention relates to a ventilator, and more specifically, in addition to performing a normal ventilation dehumidification mode, in addition to performing a ventilation mode without dehumidification, having a bypass channel for dehumidifying only room air, The present invention relates to a ventilation device having a flow path structure that bypasses a dehumidification rotor.

一般に、換気装置とは、室内空気と室外空気を入れ換えて、室内空気中の汚染物質と悪臭などを外部へ排出する一方で、室外の新鮮な空気を室内に吸い込む装置のことをいう。ところが、室内と室外間の温度及び湿度差が大きいにもかかわらず、外気をそのまま吸い込むと、室内の快適さを損ねる問題につながるため、従来の換気装置は、外気と室内空気の熱及び湿気を交換する熱交換素子を備えてきた。   In general, a ventilation device refers to a device that exchanges indoor air and outdoor air to discharge pollutants and bad odors in the indoor air to the outside while sucking fresh outdoor air into the room. However, in spite of large temperature and humidity differences between the room and the outside, if the outside air is sucked in as it is, it leads to the problem of impairing the comfort of the room. Therefore, the conventional ventilator removes the heat and humidity of the outside air and the room air. It has been equipped with a heat exchange element to replace.

また、従来の換気装置は、流路上に除湿ローターを備え、この除湿ローターと熱交換素子を通過しつつ除湿された空気が室内に供給されるようにし、また、室内空気は、熱交換素子と除湿ローターを通過しつつ室外に排気されるように構成される。   In addition, the conventional ventilation device includes a dehumidification rotor on the flow path, so that the dehumidified air is supplied into the room while passing through the dehumidification rotor and the heat exchange element, and the indoor air is connected to the heat exchange element. It is configured to be exhausted outside while passing through the dehumidifying rotor.

ここで、除湿ローターには、ゼオライトやシリカゲルのような吸湿剤を使用するが、この種の吸湿剤は、湿気を吸収しながら発熱し、４℃程度の温度上昇の特性を示す。また、除湿ローターは、継続使用のために再生部を備えるが、この再生部は、再生ヒーターに面して設けられて、吸湿した湿気を乾燥する機能を担う。   Here, a hygroscopic agent such as zeolite or silica gel is used for the dehumidifying rotor. This type of hygroscopic agent generates heat while absorbing moisture, and exhibits a temperature rise characteristic of about 4 ° C. The dehumidification rotor includes a regeneration unit for continuous use. The regeneration unit is provided facing the regeneration heater and has a function of drying moisture that has been absorbed.

この構成から、従来の換気装置では、空気が常に除湿ローターと熱交換素子を通って移動することになる。このため、除湿が不必要な場合にも空気は除湿ローターを通過しなければならず、余分の圧力消耗が起こり、また、吸湿剤によって温度が上昇する問題があった。   From this configuration, in the conventional ventilator, air always moves through the dehumidification rotor and the heat exchange element. For this reason, even when the dehumidification is unnecessary, the air must pass through the dehumidification rotor, and there is a problem that excessive pressure consumption occurs and the temperature rises due to the moisture absorbent.

しかも、従来の換気装置は、室内空気のみを独立して除湿する機能がないため、適正の除湿量を確保する上で稼動時間及び除湿ローターの容量が増加してしまい、その分、換気装置の大きさ及び設置空間が増大する、という問題点があった。   In addition, the conventional ventilator does not have the function of dehumidifying only the room air independently, so that the operating time and the capacity of the dehumidification rotor are increased in order to secure an appropriate amount of dehumidification. There was a problem that the size and installation space increased.

また、稼動時間の増加によってエネルギー消費と運転費用が増加し、室内の冷暖房負荷が増加し、運転騒音が大きくなる等の問題点があった。   In addition, there are problems such as increased energy consumption and operation costs due to increased operating hours, increased indoor heating and cooling loads, and increased operating noise.

本発明は、上記事情に鑑みて、ケーシングの一側に迂回流路を設け、室内空気のみを独立して除湿することによって、室内の湿気を效果よく除去することができ、かつ、除湿ローターを迂回する流路構造を備えて、除湿のない換気モードを可能にし、吸／排気ファンのエネルギー消費と騒音を低減しうる換気装置を提供することを目的とする。   In view of the above circumstances, the present invention provides a bypass channel on one side of the casing, and independently dehumidifies only indoor air, thereby effectively removing indoor humidity, and providing a dehumidifying rotor. It is an object of the present invention to provide a ventilator that has a bypass flow path structure, enables a ventilation mode without dehumidification, and can reduce energy consumption and noise of an intake / exhaust fan.

上記の目的を達成するために、本発明による換気装置は、ケーシングと、該ケーシングの内部に空気を流入する吸気ファンと、前記ケーシングの外部に空気を排出する排気ファンと、前記ケーシングの内部に備えられる熱交換素子と、前記熱交換素子を中心としてそれぞれ配置される複数枚の遮断板と、前記遮断板によって形成される室内空気流入流路、室内空気排出流路、室外空気流入流路及び室外空気排出流路と、前記ケーシングの内部に流入する空気を除湿する除湿ローターとを備える換気装置であって、前記室内空気流入流路と前記室外空気流入流路とを連通させる迂回流路を備えることを特徴とする。   In order to achieve the above object, a ventilation apparatus according to the present invention includes a casing, an intake fan that flows air into the casing, an exhaust fan that discharges air to the outside of the casing, and an interior of the casing. A heat exchange element provided, a plurality of shielding plates respectively arranged around the heat exchange element, an indoor air inflow channel, an indoor air discharge channel, an outdoor air inflow channel formed by the shielding plate, A ventilator comprising an outdoor air discharge flow path and a dehumidification rotor for dehumidifying air flowing into the casing, wherein a bypass flow path that connects the indoor air flow path and the outdoor air flow path It is characterized by providing.

また、前記除湿ローターは、前記ケーシングの内部の前記熱交換素子と前記排気ファンとの間の空間に備えられることを特徴とする。   The dehumidification rotor may be provided in a space between the heat exchange element and the exhaust fan inside the casing.

また、前記迂回流路が選択的に開閉されるように、この迂回流路の一端にダンパーが備えられる。   In addition, a damper is provided at one end of the bypass flow path so that the bypass flow path is selectively opened and closed.

また、前記迂回流路は、一端が前記室内空気流入流路と連通し、他端は、前記室外空気流入流路において、前記除湿ローターと、前記室外空気流入流路が外部と連通する室外空気流入口との間に備えられることを特徴とする。   The detour channel has one end communicating with the indoor air inflow channel, and the other end is outdoor air in the outdoor air inflow channel where the dehumidification rotor and the outdoor air inflow channel communicate with the outside. It is provided between the inlet and the inlet.

また、前記除湿ローターは、吸着部と再生部とに分離して備えられ、前記吸着部は、前記室外空気流入流路上に備えられ、前記再生部は、前記室内空気排出流路上に備えられることを特徴とする。   In addition, the dehumidification rotor is separately provided in an adsorption part and a regeneration part, the adsorption part is provided on the outdoor air inflow channel, and the regeneration part is provided on the indoor air discharge channel. It is characterized by.

また、前記室外空気流入流路と前記室内空気排出流路の端部には、室外と連通する室外空気流入口と室内空気排出口がそれぞれ備えられ、これら室外空気流入口と室内空気排出口には、流路を選択的に開閉するダンパーが備えられることを特徴とする。   In addition, an outdoor air inlet and an indoor air outlet that communicate with the outside are respectively provided at ends of the outdoor air inflow channel and the indoor air outlet channel, and the outdoor air inlet and the indoor air outlet are respectively provided. Is provided with a damper that selectively opens and closes the flow path.

また、前記除湿ローターは、この除湿ローターを再生するように再生部側に再生ヒーターをさらに備えることを特徴とする。   In addition, the dehumidification rotor further includes a regeneration heater on the regeneration unit side so as to regenerate the dehumidification rotor.

また、前記除湿ローターは、前記室外空気流入流路と前記室内空気排出流路で前記除湿ローターが占める断面の残り部分を遮断しうるように前記ケーシングの幅方向に亘って設置される仕切り板をさらに備えることを特徴とする。   In addition, the dehumidification rotor includes a partition plate installed across the width direction of the casing so as to block a remaining portion of a cross section occupied by the dehumidification rotor in the outdoor air inflow channel and the indoor air discharge channel. It is further provided with the feature.

また、前記仕切り板は、前記室外空気流入流路と前記室内空気吐出流路上にそれぞれダンパーを備えることを特徴とする。   Further, the partition plate includes a damper on each of the outdoor air inflow channel and the indoor air discharge channel.

本発明による換気装置は、除湿換気だけでなく、独立除湿も可能であるため、室内の湿度が高いときに効率よく湿度を下げることが可能になる。また、本発明は、換気システム及び除湿ローターの機能を独立的あるいは相互的に構成可能であるため、換気による室内湿度の低減のほかに、目標湿度まで室内湿度を下げることも可能になるため、夏季など室内湿度上昇による室内のかび発生を防止し、洗濯物の室内乾燥効果を改善する効果が得られる。   Since the ventilator according to the present invention can perform not only dehumidification ventilation but also independent dehumidification, it is possible to efficiently reduce the humidity when the indoor humidity is high. In addition, since the functions of the ventilation system and the dehumidification rotor can be configured independently or mutually in the present invention, in addition to reducing the indoor humidity by ventilation, the indoor humidity can be lowered to the target humidity. It is possible to prevent the occurrence of mold in the room due to an increase in indoor humidity such as in summer and to improve the effect of drying the laundry indoors.

また、本発明による換気装置は、独立除湿モードにおいて除湿ローターの再生部と吸着部を通る室内空気間に熱交換がなされるようにしたため、室内に流入する空気は冷却されて冷房負荷が減少する一方で、室外に排出される室内空気は加熱されて再生ヒーターの電力消耗が減少する効果が得られる。   In the ventilator according to the present invention, in the independent dehumidification mode, heat is exchanged between the indoor air passing through the regeneration unit and the adsorption unit of the dehumidification rotor, so that the air flowing into the room is cooled and the cooling load is reduced. On the other hand, the indoor air discharged to the outside is heated, and an effect of reducing the power consumption of the regenerative heater can be obtained.

また、本発明による換気装置は、除湿のない換気モードでは、ダンパーを用いて大部分の室内空気が除湿ローターの吸着部を迂回する流路構造を備えるため、吸気ファンの消費電力及び騒音を減少させることができ、除湿換気モードまたは除湿のない換気モードでは、排出する室内空気の一部だけを除湿ローターの再生部に通過させるため、排気ファンの消費電力及び騒音を低減させることが可能になる。   In addition, the ventilation device according to the present invention has a flow path structure in which most of the room air bypasses the adsorption part of the dehumidification rotor using a damper in the ventilation mode without dehumidification, thereby reducing the power consumption and noise of the intake fan. In the dehumidification ventilation mode or the non-dehumidification ventilation mode, only a part of the exhausted room air is passed through the regeneration unit of the dehumidification rotor, so that it is possible to reduce the power consumption and noise of the exhaust fan. .

また、本発明による換気装置は、除湿ローターが熱交換素子や換気部分と分離されていることからシステムの大きさが大きかった従来の換気装置とは違い、除湿ローターの再生部を排気ファンの設置空間に設置し、室外空気流入口側の流路を除湿ローターの吸着部空間として活用するため、従来の換気装置に比べて大きさが減少する効果が得られる。   Further, the ventilator according to the present invention is different from the conventional ventilator in which the dehumidification rotor is separated from the heat exchanging element and the ventilation part and thus the size of the system is large. Since it is installed in the space and the flow path on the outdoor air inlet side is utilized as the adsorption part space of the dehumidifying rotor, the effect of reducing the size as compared with the conventional ventilation device can be obtained.

以下、本発明の好ましい実施形態について、添付図面を参照しつつ詳細に説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図１は、本発明による換気装置を示す斜視図である。図１に示すように、本発明による換気装置は、直方体形状のケーシング１を備え、このケーシング１の対向する両側面のうち、一側面には室内空気流入口４及び室外空気排出口５が、他側面には室外空気流入口３及び室内空気排出口２が設けられて、室内空気を吸い込んで室外に排出したり、室外空気を吸い込んで室内に供給したりする。ケーシング１の内部には、熱交換素子８を中心として長手方向及び幅方向に遮断板１８，１９がそれぞれ配置されて流路を形成し、これによって、ケーシング内部で室外空気と室内空気が相互に混合することが防止される。   FIG. 1 is a perspective view showing a ventilation device according to the present invention. As shown in FIG. 1, the ventilator according to the present invention includes a rectangular parallelepiped casing 1, and among both opposing side surfaces of the casing 1, an indoor air inlet 4 and an outdoor air outlet 5 are provided on one side surface. On the other side, an outdoor air inlet 3 and an indoor air discharge port 2 are provided, and the indoor air is sucked and discharged outside, or the outdoor air is sucked and supplied indoors. Inside the casing 1, shielding plates 18 and 19 are arranged in the longitudinal direction and the width direction around the heat exchange element 8 to form a flow path, whereby outdoor air and indoor air are mutually exchanged inside the casing. Mixing is prevented.

これら流入口３，４、排出口２，５及び遮断板１８，１９によって、ケーシング１には４つの基本的な流路が形成される。すなわち、室外空気流入口３を通過して熱交換素子８に至るまでの室外空気流入流路(Ａ)、熱交換素子８から吸気ファン６を通過して室外空気排出口５に至るまでの室外空気排出流路(Ｂ)、室内空気流入口４を通過して熱交換素子８に至るまでの室内空気流入流路(Ｃ)、熱交換素子８から排気ファン７を通過して室内空気排出口２に至るまでの流路(Ｄ)が形成される。この他にも、迂回流路１６と仕切り板９により空気の流れが変わるが、これは後述する。   By these inflow ports 3 and 4, the discharge ports 2 and 5 and the blocking plates 18 and 19, four basic flow paths are formed in the casing 1. That is, the outdoor air inflow channel (A) from the outdoor air inlet 3 to the heat exchange element 8, and the outdoor from the heat exchange element 8 to the outdoor air outlet 5 through the intake fan 6. An air exhaust passage (B), an indoor air inflow passage (C) from the indoor air inlet 4 to the heat exchange element 8, and an exhaust air fan 7 through the exhaust fan 7 from the heat exchange element 8. A channel (D) up to 2 is formed. In addition, the air flow is changed by the bypass channel 16 and the partition plate 9, which will be described later.

熱交換素子８は、六方体形状を有し、空気が両方向に通過しやすくなるようにケーシング１の略中心部に所定の角度をもって設けられる。また、熱交換素子８の内部は層状構造となっているため、いずれか一方向に空気が通過する際に、他の方向には空気が通過することができない。また、熱交換素子８の層状構造は、相互に異なる方向に通過する室外空気と室内空気の湿気と熱を吸収し交換させる役割を担う。   The heat exchange element 8 has a hexagonal shape and is provided at a predetermined angle at a substantially central portion of the casing 1 so that air can easily pass in both directions. Moreover, since the inside of the heat exchange element 8 has a layered structure, when air passes in any one direction, the air cannot pass in the other direction. The layered structure of the heat exchange element 8 plays a role of absorbing and exchanging the humidity and heat of the outdoor air and the indoor air that pass in different directions.

ケーシング１の内部には、熱交換素子８を介在して吸気ファン６と排気ファン７が配置され、これら吸気ファン６と排気ファン７との間には遮断板１９ａが配置される。吸気ファン６は、室外空気流入口３から室外空気を吸い込んで室外空気排出口５を通して室内に供給する役割を担い、排気ファン７は、室内空気流入口４から汚染した室内空気を吸い込んで室内空気排出口２を通して排出する役割を担う。   An intake fan 6 and an exhaust fan 7 are disposed inside the casing 1 with a heat exchange element 8 interposed therebetween, and a blocking plate 19 a is disposed between the intake fan 6 and the exhaust fan 7. The intake fan 6 plays a role of sucking outdoor air from the outdoor air inlet 3 and supplying it to the room through the outdoor air outlet 5, and the exhaust fan 7 sucks contaminated room air from the indoor air inlet 4 to indoor air. It plays a role of discharging through the discharge port 2.

熱交換素子８と排気ファン７との間には除湿ローター１０が備えられ、室外空気流入口３から室内に流入する室外空気の湿気を除去する。この除湿ローター１０は、継続使用のために、再生部と吸着部とに画設される。つまり、本発明に適用される除湿ローター１０は、ディスク形状の回転可能な構造を有し、その一面にはモーターが取り付けられ、かつ、円形断面の３／４に該当する部分は吸着部として室外空気流入口３の側に備えられ、残る１／４部分は再生部として室内空気排出口２の側に備えられる。   A dehumidification rotor 10 is provided between the heat exchange element 8 and the exhaust fan 7 to remove the humidity of the outdoor air flowing into the room from the outdoor air inlet 3. The dehumidification rotor 10 is provided in the regeneration unit and the adsorption unit for continuous use. That is, the dehumidification rotor 10 applied to the present invention has a disk-shaped rotatable structure, a motor is attached to one surface thereof, and a portion corresponding to 3/4 of the circular cross section is an outdoor portion as an adsorption portion. It is provided on the air inlet 3 side, and the remaining ¼ part is provided on the indoor air outlet 2 side as a regeneration unit.

このため、室外空気流入口３と室内空気排出口２との間の遮断板１８ｂは、中央の部分が四分円の両半径線と一致するように、室外空気流入口３に向いて“V”形状に突出形成される。一方、除湿ローターの再生部１０ｂに面する箇所には再生ヒーター１１が取り付けられ、この再生ヒーター１１は、除湿ローター１０が除湿過程中に吸収した水分を蒸発させることによって、除湿ローター１０の継続的な使用を可能にする。場合によっては、排気ファン７と熱交換素子８との間に備えられる、除湿ローター１０の取り付けられた仕切り板９は、空気が通る除湿ローター１０の面積をより大きくするように、所定の角度を有してもいい。   For this reason, the blocking plate 18b between the outdoor air inlet 3 and the indoor air outlet 2 faces the outdoor air inlet 3 so that the center portion thereof coincides with both radial lines of the quadrant. "It is formed in a protruding shape. On the other hand, a regeneration heater 11 is attached to a portion of the dehumidification rotor facing the regeneration unit 10b, and the regeneration heater 11 continuously evaporates the dehumidification rotor 10 by evaporating the moisture absorbed by the dehumidification rotor 10 during the dehumidification process. Can be used. In some cases, the partition plate 9 with the dehumidifying rotor 10 provided between the exhaust fan 7 and the heat exchange element 8 has a predetermined angle so as to increase the area of the dehumidifying rotor 10 through which air passes. You can have it.

仕切り板９には、遮断板１８ｂを基準にしてダンパー１４，１５がそれぞれ配設され、これによって、空気が選択的に流入または流出される。また、室外空気流入口３と室内空気排出口２のそれぞれに接するケーシング１の内部側にもダンパー１３，１２がそれぞれ備えられ、これによって、流路の選択的開閉が可能になる。   The partition plate 9 is provided with dampers 14 and 15 with respect to the blocking plate 18b as a reference, so that air selectively flows in or out. In addition, dampers 13 and 12 are also provided on the inner side of the casing 1 in contact with the outdoor air inlet 3 and the indoor air outlet 2, respectively, so that the channel can be selectively opened and closed.

ケーシング１内の一側には迂回流路１６が備えられるが、室内空気流入口４と連通する一端部にはダンパー１７が備えられるため、室内空気流入口４から流入する室内空気の方向、つまり、迂回流路１６を通過するか否かを選択することができる。一方、ダンパーの設けられていない迂回流路１６の他端部は、室外空気流入口３近傍の流路と連通する。   A bypass channel 16 is provided on one side of the casing 1, but a damper 17 is provided at one end communicating with the indoor air inlet 4. It can be selected whether or not to pass through the detour channel 16. On the other hand, the other end portion of the bypass channel 16 where no damper is provided communicates with the channel near the outdoor air inlet 3.

図２は、除湿換気モードを遂行している本発明による換気装置を示す断面図である。   FIG. 2 is a cross-sectional view illustrating a ventilator according to the present invention performing a dehumidifying ventilation mode.

本発明による換気装置は、迂回流路１６と複数個のダンパー１２，１３，１４，１５，１７を備えるため、換気及び除湿を同時に遂行する一般的な除湿換気モードの他にも、室内の空気のみを除湿する独立除湿モード、及び除湿は遂行せずに換気だけを遂行する除湿のない換気モードを実現することができる。なかでも、図２では、除湿と換気を同時に遂行する除湿換気モードについて説明する。   Since the ventilator according to the present invention includes the bypass channel 16 and the plurality of dampers 12, 13, 14, 15, and 17, in addition to a general dehumidification ventilation mode that simultaneously performs ventilation and dehumidification, Independent dehumidification mode for dehumidifying only and ventilation mode without dehumidification for performing only ventilation without performing dehumidification can be realized. Especially, FIG. 2 demonstrates the dehumidification ventilation mode which performs dehumidification and ventilation simultaneously.

除湿換気モードは、室内空気流入口４から汚れた室内空気を吸い込み、これを熱交換素子８を経て室外に排出し、新鮮な室外の空気を、熱交換素子８と除湿ローター１０を経て除湿し室内に供給する一般的な換気装置のモードである。この除湿換気モードにおける換気装置内の空気の流れを各装置と関連して説明すると、下記の通りである。   In the dehumidifying ventilation mode, dirty indoor air is sucked from the indoor air inlet 4 and is discharged to the outside through the heat exchange element 8, and fresh outdoor air is dehumidified through the heat exchange element 8 and the dehumidifying rotor 10. It is a mode of a general ventilation device that supplies indoors. The flow of air in the ventilation device in the dehumidification ventilation mode will be described below in relation to each device.

まず、吸気ファン６と排気ファン７が定格で作動すると、室外空気流入口３のダンパー１３と、室内空気排出口２のダンパー１２が開き、これによって、室外空気は、室外空気流入口３から仕切り板９に装着されている除湿ローター１０の吸着部１０ａを通りつつ除湿される。続いて、除湿ローター１０を通過した室外空気は、熱交換素子８を通過しつつ熱を吸収し湿気を放出した状態で室内に供給される。すなわち、除湿ローター１０を通過した室外空気は、室内空気が通過しつつ熱交換素子８に伝達した熱を吸収する一方で、残っている湿気を熱交換素子８に奪われつつ、吸気ファン６を介して室内に吐出される。   First, when the intake fan 6 and the exhaust fan 7 are operated at rated values, the damper 13 of the outdoor air inlet 3 and the damper 12 of the indoor air outlet 2 are opened, whereby the outdoor air is separated from the outdoor air inlet 3. Dehumidification is performed while passing through the suction portion 10a of the dehumidification rotor 10 mounted on the plate 9. Subsequently, the outdoor air that has passed through the dehumidifying rotor 10 is supplied to the room in a state of absorbing heat and releasing moisture while passing through the heat exchange element 8. In other words, the outdoor air that has passed through the dehumidifying rotor 10 absorbs the heat transferred to the heat exchange element 8 while the room air passes, while the remaining moisture is taken away by the heat exchange element 8 and the intake fan 6 is removed. Through the room.

一方、室内空気は、室内空気流入口４から換気装置の内部に流入する。この除湿換気モードでは迂回流路１６が使用されないため、ダンパー１７は閉じたままとなる。したがって、流入した室内空気は、熱交換素子８を通過しつつ熱は放出し、湿気は吸収した状態で、除湿ローター１０の再生部１０ｂを通る。   On the other hand, room air flows into the ventilator from the room air inlet 4. In this dehumidifying ventilation mode, the bypass channel 16 is not used, so that the damper 17 remains closed. Accordingly, the indoor air that has flowed in passes through the regeneration unit 10b of the dehumidification rotor 10 while passing through the heat exchange element 8 and releasing heat and absorbing moisture.

ここで、仕切り板９には、除湿ローター１０の他にも、空気の流れを制御するように二つのダンパー１４，１５が設けられる。このダンパー１４，１５は、遮断板１８ｂを中心として相互に異なる流路に配置される。室内空気を室外に吐出す場合に、除湿ローター１０の再生部１０ｂ側に設けられたダンパー１４は、再生部１０ｂを通る空気の流量を設計流量に合わせるべく、完全または一部が開く。除湿ローター１０の再生部１０ｂを通過しつつ室内空気は、再生部１０ｂに吸収されている湿気を奪った状態で排気ファン７を介して室内空気排出口２から外部へ吐出される。   Here, in addition to the dehumidifying rotor 10, the partition plate 9 is provided with two dampers 14 and 15 so as to control the flow of air. The dampers 14 and 15 are disposed in mutually different flow paths around the blocking plate 18b. When the room air is discharged to the outside, the damper 14 provided on the regeneration unit 10b side of the dehumidification rotor 10 is completely or partially opened so that the flow rate of the air passing through the regeneration unit 10b matches the design flow rate. While passing through the regenerating unit 10b of the dehumidifying rotor 10, the room air is discharged from the indoor air discharge port 2 to the outside through the exhaust fan 7 in a state where the moisture absorbed by the regenerating unit 10b is taken away.

図３は、独立除湿モードを遂行している本発明による換気装置を示す断面図である。   FIG. 3 is a cross-sectional view illustrating a ventilator according to the present invention performing an independent dehumidification mode.

上にも述べたように、独立除湿モードは、室内空気だけを除湿するモードであり、大部分の空気は、迂回流路１６を通過して除湿ローター１０で除湿された後に、室内に再流入し、残る一部の空気は外部へ排出される。次に、この独立除湿モードを遂行する場合の換気装置における空気の流れを、各装置と関連して説明する。   As described above, the independent dehumidifying mode is a mode for dehumidifying only room air, and most of the air passes through the bypass channel 16 and is dehumidified by the dehumidifying rotor 10 and then re-enters the room. The remaining part of the air is discharged to the outside. Next, the air flow in the ventilator when performing this independent dehumidification mode will be described in relation to each device.

独立除湿モードにおいて、吸気ファン６は、定格またはそれ以上の回転数で作動し、排気ファン７は、除湿換気モードよりも小さい回転数(rpm)で回転し、これによって、室内空気は、室内空気流入口４から換気装置の内部に流入する。このときに、迂回流路１６と連通するダンパー１７は開く一方で、室外空気流入口３はダンパー１３によって閉じる。このように、吸気ファン６が作動し、ダンパー１３は閉じているため、ケーシング１の室外空気流入口３側には負圧が形成される。   In the independent dehumidification mode, the intake fan 6 operates at a rotational speed that is higher than or equal to the rated speed, and the exhaust fan 7 rotates at a rotational speed (rpm) that is smaller than that in the dehumidification ventilation mode. It flows into the inside of the ventilator from the inlet 4. At this time, the damper 17 communicating with the bypass channel 16 is opened, while the outdoor air inlet 3 is closed by the damper 13. Thus, since the intake fan 6 operates and the damper 13 is closed, a negative pressure is formed on the outdoor air inlet 3 side of the casing 1.

このような負圧の発生によって、室内空気流入口４を通過した室内空気は、ダンパー１７を経て迂回流路１６に流れる。上述したように、迂回流路１６の一端は、ダンパー１７を介して室内空気流入口４と連通可能になっており、他端は、仕切り板９と室外空気流入口３との間の箇所と連通するようになっているため、室内空気は、ケーシング１内の仕切り板９と室外空気流入口３との間の箇所に流入し、除湿ローター１０の吸着部１０ａを通過しつつ大部分の湿気が除去される。除湿ローター１０を通過した室内空気は、熱交換素子８を経て吸気ファン６を介して室内へ再び供給される。   Due to the generation of such negative pressure, the room air that has passed through the room air inlet 4 flows to the bypass channel 16 via the damper 17. As described above, one end of the bypass channel 16 can communicate with the indoor air inlet 4 via the damper 17, and the other end is connected to a location between the partition plate 9 and the outdoor air inlet 3. Since the air is communicated, the room air flows into a portion between the partition plate 9 in the casing 1 and the outdoor air inlet 3 and passes through the adsorbing portion 10a of the dehumidifying rotor 10 so that most of the moisture. Is removed. The room air that has passed through the dehumidifying rotor 10 is supplied again to the room through the heat exchange element 8 and the intake fan 6.

一方、室内空気排出口２が開いており、排気ファン７が小さい回転数で作動しているため、室内空気流入口４からダンパー１７を通して迂回流路１６に流入しなかった残りの室内空気は、熱交換素子８を経て室内空気排出口２側に流れるようになる。このときに、除湿ローター１０の再生部側のダンパー１４は閉じているため、室内空気排出口２側に流れる空気は全て、除湿ローター１０の再生部１０ｂを経て室内空気排出口２から外部に排出される。   On the other hand, since the indoor air discharge port 2 is open and the exhaust fan 7 is operating at a low rotational speed, the remaining indoor air that has not flowed into the bypass channel 16 from the indoor air inlet 4 through the damper 17 is It flows to the indoor air outlet 2 side through the heat exchange element 8. At this time, since the damper 14 on the regeneration unit side of the dehumidification rotor 10 is closed, all the air flowing to the indoor air discharge port 2 side is exhausted to the outside from the indoor air discharge port 2 through the regeneration unit 10b of the dehumidification rotor 10. Is done.

ここで、除湿ローター１０の再生部１０ｂを通過する空気の流量は、室内に再流入する空気の流量に比べて少ないため、換気と独立して除湿を遂行することが可能になる。このときに、除湿ローター１０の再生部１０ｂに流入する一部の室内空気は、熱交換素子８を通りつつ予熱されるが、これは、迂回流路１６を通って除湿ローター１０の吸着部１０ａで除湿されて温度の上昇した室内空気が、熱交換素子８と交換した熱を吸収するからである。   Here, since the flow rate of the air passing through the regeneration unit 10b of the dehumidification rotor 10 is smaller than the flow rate of the air re-entering the room, it is possible to perform dehumidification independently of ventilation. At this time, a part of the room air flowing into the regeneration unit 10b of the dehumidification rotor 10 is preheated while passing through the heat exchange element 8, and this is passed through the bypass channel 16 and is adsorbed by the adsorption unit 10a of the dehumidification rotor 10. This is because the room air that has been dehumidified and whose temperature has increased absorbs the heat exchanged with the heat exchange element 8.

また、迂回流路１６を通って室内に再流入される空気は、室内空気排出口２から排出される、除湿されなかった室内空気と熱交換素子８で熱交換され冷却された状態で室内に流入されるため、従来の排気型換気装置に比べて冷房負荷が減少することになる。   In addition, the air re-entered into the room through the bypass channel 16 is exhausted from the indoor air discharge port 2 into the room in a state where heat is exchanged with the indoor air that has not been dehumidified and is cooled by the heat exchange element 8. Since the air flows in, the cooling load is reduced as compared with the conventional exhaust ventilation device.

この独立除湿モードは、換気をしながらも室内の絶対的な湿度量を下げる効果があるため、高温多湿な梅雨のときや乾かすべき洗濯物が室内にある場合など、室内の湿度湿気が高い場合に、より有効に換気及び除湿を遂行する利点がある。   This independent dehumidification mode has the effect of lowering the absolute humidity of the room while ventilating, so when the humidity in the room is high, such as in hot and humid rainy season or when there is laundry to be dried in the room Has the advantage of carrying out ventilation and dehumidification more effectively.

図４は、除湿のない換気モードを遂行している本発明による換気装置を示す断面図である。   FIG. 4 is a cross-sectional view showing a ventilator according to the present invention performing a ventilation mode without dehumidification.

除湿のない換気モードは、除湿機能は要らなく、むしろ換気量だけを増加させたい場合に使用するモードであって、除湿ローター１０を通過する必要がないため、圧力損失が減り、風量が増加する効果が得られる。   The ventilation mode without dehumidification does not require a dehumidification function, but rather is a mode used when it is desired to increase only the ventilation amount, and it is not necessary to pass through the dehumidification rotor 10, so that the pressure loss is reduced and the air volume is increased. An effect is obtained.

除湿のない換気モードは、除湿ローター１０の吸着部１０ａ側に設けられたダンパー１５が開く以外は、除湿換気モードと同一の流路構造を有する。このモードでは、除湿ローター１０と再生ヒーター５に印加される電源を遮断するため、除湿ローター１０は回転せず、よって、除湿は遂行されない。   The ventilation mode without dehumidification has the same flow path structure as the dehumidification ventilation mode except that the damper 15 provided on the suction portion 10a side of the dehumidification rotor 10 opens. In this mode, since the power applied to the dehumidification rotor 10 and the regenerative heater 5 is cut off, the dehumidification rotor 10 does not rotate, and therefore dehumidification is not performed.

この除湿のない換気モードにおいても、流入する室外空気が、除湿ローター１０を通りつつ相当なる圧力損失を招き、余分の吸気ファン６の動力消費につながる問題や、除湿ローター１０の抵抗による騒音増加の問題が生ずるが、これは、ダンパー１５を開くことによって解消可能である。また、同じ効果を得るために、除湿ローター１０の再生部１０ｂ側に設けられたダンパー１４も完全に開く。また、吸着部１０ａ側のダンパー１５の開きによって得られる効果が不必要な場合には、このダンパー１５を他の部材や流路構造に変更することなく除去してもいい。   Even in this ventilation mode without dehumidification, inflowing outdoor air causes a considerable pressure loss while passing through the dehumidification rotor 10, leading to power consumption of the extra intake fan 6, and noise increase due to resistance of the dehumidification rotor 10. Problems arise but can be resolved by opening the damper 15. Further, in order to obtain the same effect, the damper 14 provided on the regeneration unit 10b side of the dehumidification rotor 10 is also completely opened. If the effect obtained by opening the damper 15 on the suction portion 10a side is unnecessary, the damper 15 may be removed without changing to another member or a flow path structure.

図５は、仕切り板９に除湿ローター１０が取り付けられた様子を示すものであって、除湿ローター１０の再生部１０ｂ側にダンパー１４が設けられ、吸着部１０ａ側にダンパー１５が設けられている。ここで、除湿ローター１０は、断面の１／４は再生部１０ｂとして使用され、残りの３／４は吸着部１０ａとして使用されている。   FIG. 5 shows a state in which the dehumidification rotor 10 is attached to the partition plate 9. The damper 14 is provided on the regeneration unit 10 b side of the dehumidification rotor 10, and the damper 15 is provided on the suction unit 10 a side. . Here, in the dehumidification rotor 10, ¼ of the cross section is used as the regeneration unit 10b, and the remaining 3/4 is used as the adsorption unit 10a.

また、遮断板１８ｂは、除湿ローター１０の再生部１０ｂを境界付ける２つの半径線に沿って“V”形状をもって室外空気流入流路の方に突出して設けられる。   Further, the blocking plate 18b is provided to protrude toward the outdoor air inflow channel with a “V” shape along two radial lines that bound the regeneration portion 10b of the dehumidifying rotor 10.
