The heat absorber 9 cools and dehumidifies the air to be dehumidified. The radiator 7 and the heat absorber 9 are arranged to face each other. The radiator 7 is arranged on the front side of the main body case 1, and the heat absorber 9 is arranged on the rear side of the main body case 1.
図３は、熱交換器４の構成を示す概略図である。図２、３に示すように、熱交換器４は、伝熱板Ａ１１および伝熱板Ｂ１２を交互に積層することにより構成されており、それぞれの伝熱板には、積層した際に風路が構成できるようにリブ１３が設けられている。そして、鉛直方向に流れる第１熱交換風路１４と、水平に流れる第２熱交換風路１５とを構成し、この風路間でそれぞれの伝熱板を介して熱交換を行っている。熱交換器４は、伝熱板を積層した状態で下面が傾斜した立方体となり、放熱器７と吸熱器９との間で、吸熱器９から放熱器７への風路中に設けられている。 FIG. 3 is a schematic diagram showing the configuration of the heat exchanger 4. As shown in FIGS. 2 and 3, the heat exchanger 4 is configured by alternately stacking heat transfer plates A11 and B12, and each heat transfer plate has an air passage when stacked. The ribs 13 are provided so that the above can be configured. Then, a first heat exchange air passage 14 that flows in the vertical direction and a second heat exchange air passage 15 that horizontally flows are configured, and heat is exchanged between the air passages through the respective heat transfer plates. The heat exchanger 4 is a cube whose lower surface is inclined in a state in which heat transfer plates are stacked, and is provided between the radiator 7 and the heat absorber 9 in the air passage from the heat absorber 9 to the radiator 7. ..
送風機５は、スクロール形状のケーシング部１６と、このケーシング部１６に固定されたモータ部１７と、このモータ部１７によって回転する羽根部１８とから形成している。ケーシング部１６は、吸込口１９と吐出口２０とを備えている。この吸込口１９は、放熱器７に対向している。吸熱器９と、熱交換器４の第２熱交換風路１５と、放熱器７と、送風機５とは、水平方向に一直線上に配置されている。すなわち、吸熱器９と、熱交換器４と、放熱器７と、吸込口１９とは、一直線上に風路を有するものである。 The blower 5 includes a scroll-shaped casing portion 16, a motor portion 17 fixed to the casing portion 16, and a blade portion 18 rotated by the motor portion 17. The casing 16 includes a suction port 19 and a discharge port 20. The suction port 19 faces the radiator 7. The heat absorber 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5 are arranged in a straight line in the horizontal direction. That is, the heat absorber 9, the heat exchanger 4, the radiator 7, and the suction port 19 have an air passage on a straight line.
送風機５によって、矢印に示すように、空気吸込口２からに吸気した空気は、熱交換器４の第１熱交換風路１４へ流入して、すでに吸熱器９により冷却除湿された空気と熱交換して予冷されたのち、吸熱器９における熱交換器４の底面より下方に突出した部分を通過し、その後風向を反転させ、さらに吸熱器９の残りの部分を通って冷却除湿される。なお、熱交換器４の底面より下方に突出した部分は通過せず、吸熱器９に一度のみ通過する風路もある。また、吸熱器９は、熱交換器４の底面から突出させず、吸熱器９の下端と熱交換器４の底面の上端とを同じ高さにしてもよい。 As shown by the arrow, the air taken in from the air suction port 2 by the blower 5 flows into the first heat exchange air passage 14 of the heat exchanger 4, and the air already cooled and dehumidified by the heat absorber 9 and the heat. After being exchanged and pre-cooled, the heat absorber 9 passes through a portion of the heat absorber 9 that protrudes downward from the bottom surface of the heat exchanger 4, then the wind direction is reversed, and the remaining portion of the heat absorber 9 is cooled and dehumidified. In addition, there is an air passage which does not pass through the portion projecting downward from the bottom surface of the heat exchanger 4 and passes through the heat absorber 9 only once. Further, the heat absorber 9 may not be projected from the bottom surface of the heat exchanger 4, and the lower end of the heat absorber 9 and the upper end of the bottom surface of the heat exchanger 4 may be at the same height.
冷却除湿された空気は熱交換器４の第２熱交換風路１５に流入し空気吸込口２から吸気した空気によって加熱され、放熱器７でさらに加熱され、送風機５によって機外に送風される。上記風路が、除湿を行う除湿経路２１となる。 The air that has been cooled and dehumidified is heated by the air that has flowed into the second heat exchange air passage 15 of the heat exchanger 4 and that has been taken in through the air suction port 2, is further heated by the radiator 7, and is blown outside by the blower 5. .. The air passage serves as a dehumidifying path 21 for dehumidifying.
熱交換器４および吸熱器９の下方には、水受け手段２２が設置されている。水受け手段２２には、熱交換器４の第１熱交換風路１４および吸熱器９に生成される結露水が滴下する。すなわち、空気吸込口２から流入した空気が熱交換器４にて予冷される段階で、第１熱交換風路１４内で水分が結露して水滴となって滴下することがあるが、熱交換器４の下方に除湿経路２１を兼ねた水受け手段２２を配置して結露水を受ける構造となっている。 Water receiving means 22 is installed below the heat exchanger 4 and the heat absorber 9. The dew condensation water generated in the first heat exchange air passage 14 of the heat exchanger 4 and the heat absorber 9 drops in the water receiving means 22. That is, when the air flowing in from the air suction port 2 is pre-cooled by the heat exchanger 4, water may condense in the first heat exchange air passage 14 and drop as water droplets. A water receiving means 22 which also serves as a dehumidifying path 21 is arranged below the vessel 4 to have a structure for receiving condensed water.
また、本体ケース１内の水受け手段２２の下部には、結露水を貯水するタンク２４を備え、水受け手段２２に設けた、たまった水滴をタンク２４に導出するドレン孔２５を通って、除湿水はタンク２４に回収される。 In addition, a tank 24 for storing condensed water is provided below the water receiving means 22 in the main body case 1, and passes through a drain hole 25 provided in the water receiving means 22 for discharging accumulated water droplets to the tank 24. The dehumidified water is collected in the tank 24.
また、吸熱器９の熱交換器４の反対側（本体ケース１の空気吸込口２側）で、水受け手段２２の上方には、吸熱器カバー２３を設ける。水受け手段２２と吸熱器カバー２３は、除湿経路２１における熱交換器４の第１熱交換風路１４から吸熱器９までの風路の一部である。 Further, a heat sink cover 23 is provided on the opposite side of the heat absorber 9 to the heat exchanger 4 (on the air suction port 2 side of the main body case 1) and above the water receiving means 22. The water receiving means 22 and the heat absorber cover 23 are a part of the air passage from the first heat exchange air passage 14 of the heat exchanger 4 to the heat absorber 9 in the dehumidification passage 21.
本実施形態における特徴は、第１の除湿経路２１ａと、第２の除湿経路２１ｂと、を備えた構成としたことである。第１の除湿経路２１ａは、送風機５によって空気吸込口２から本体ケース１内に吸い込まれた空気が、熱交換器４の第１熱交換風路１４、吸熱器９、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出る風路である。第２の除湿経路２１ｂは、送風機５によって空気吸込口２から本体ケース１内に吸い込まれた空気が、吸熱器９、吸熱器９、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出る風路である。 The feature of the present embodiment is that the first dehumidifying path 21a and the second dehumidifying path 21b are provided. In the first dehumidification path 21 a, the air sucked into the main body case 1 from the air suction port 2 by the blower 5 is the first heat exchange air passage 14 of the heat exchanger 4, the heat absorber 9, and the first heat exchange device 4 of the heat exchanger 4. 2 is an air passage that blows out from the air outlet 3 to the outside of the main body case 1 via the heat exchange air passage 15, the radiator 7, and the blower 5. In the second dehumidification path 21b, the air sucked into the main body case 1 from the air suction port 2 by the blower 5 is the heat absorber 9, the heat absorber 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator. 7, an air passage blown out of the body case 1 from the air outlet 3 via the blower 5.
なお、第１の除湿経路２１ａと第２の除湿経路２１ｂは、空気吸込口２までは、同一の経路であり、本体ケース１内で、それぞれの経路に分かれる。そして、第１の除湿経路２１ａは、熱交換器４の第１熱交換風路１４を、第２の除湿経路２１ｂは、吸熱器９を通過した後に、合流し、再び同一の経路となり、吸熱器９、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出す。 The first dehumidifying path 21a and the second dehumidifying path 21b are the same path up to the air suction port 2 and are divided into respective paths in the main body case 1. Then, the first dehumidifying path 21a merges with the first heat exchanging air path 14 of the heat exchanger 4, and the second dehumidifying path 21b merges after passing through the heat absorber 9 to become the same path again, thereby absorbing heat. The air is blown from the air outlet 3 to the outside of the main body case 1 through the air conditioner 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5.
これにより、熱交換器４の第２熱交換風路１５の風量が増加し、熱交換器４を十分に冷却させることができるので、第１熱交換風路１４の冷却が十分に行えるので、結果として、除湿性能を向上させることができる。 As a result, the air volume of the second heat exchange air passage 15 of the heat exchanger 4 is increased, and the heat exchanger 4 can be sufficiently cooled, so that the first heat exchange air passage 14 can be sufficiently cooled. As a result, the dehumidification performance can be improved.
また、吸熱器９と、熱交換器４の第２熱交換風路１５と、放熱器７と、送風機５とは、本体ケース１における前後方向に一直線上に配置されている。吸熱器９の上端は、熱交換器４の天面より上方に突出している。第２の除湿経路２１ｂは、送風機５によって空気吸込口２から本体ケース１内に吸い込んだ空気を、熱交換器４の天面より上方に配置された吸熱器９、熱交換器４の天面より下方に配置された吸熱器９、熱交換器４の第２熱交換風路１５、放熱器７、送風機５を介して空気吹出口３から本体ケース１外に吹き出す構成にしてもよい。 Further, the heat absorber 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5 are arranged in a straight line in the front-rear direction of the main body case 1. The upper end of the heat absorber 9 projects above the top surface of the heat exchanger 4. The second dehumidification path 21b is a heat absorber 9 arranged above the top surface of the heat exchanger 4, the top surface of the heat exchanger 4, the air sucked into the main body case 1 from the air suction port 2 by the blower 5. A configuration may be adopted in which the air is blown from the air outlet 3 to the outside of the main body case 1 via the heat absorber 9, the second heat exchange air passage 15 of the heat exchanger 4, the radiator 7, and the blower 5 arranged below.
冷凍サイクルでは、圧縮機６で冷媒を圧縮するため、圧縮機６へ流れ込む冷媒は、吸熱器９で十分に気化させるのが一般的である。つまり、吸熱器９の冷媒下流側においては冷媒が気化しているため、冷媒上流側よりも温度が高くなる。 In the refrigeration cycle, since the refrigerant is compressed by the compressor 6, the refrigerant flowing into the compressor 6 is generally sufficiently vaporized by the heat absorber 9. That is, since the refrigerant is vaporized on the refrigerant downstream side of the heat absorber 9, the temperature becomes higher than that on the refrigerant upstream side.
本発明では、熱交換器４では、吸熱器９で冷却された空気が第２熱交換風路１５を通過することによって冷やされるが、吸熱器９の冷媒下流側のみを通過した後の空気では、十分に熱交換器４を冷却することができない。 In the present invention, in the heat exchanger 4, the air cooled in the heat absorber 9 is cooled by passing through the second heat exchange air passage 15, but in the air after passing only the refrigerant downstream side of the heat absorber 9, , The heat exchanger 4 cannot be cooled sufficiently.
そこで、第２の除湿経路２１ｂにおいて、熱交換器４の天面より上方に配置された吸熱器９、熱交換器４の天面より下方に配置された吸熱器９の順に通過させることによって、吸熱器９上部の、冷媒下流側で冷媒が気化し比較的温度が高い領域を通過した空気が、吸熱器９下部の冷媒上流側を通過し、十分に冷却された後に、熱交換器の第２熱交換風路１５に供給されることで、熱交換器全体が冷却される。結果として、除湿性能を向上させることができる。 Therefore, in the second dehumidification path 21b, by passing the heat absorber 9 arranged above the top surface of the heat exchanger 4 and the heat absorber 9 arranged below the top surface of the heat exchanger 4 in this order, The air that has passed through the region in which the refrigerant vaporizes on the refrigerant downstream side of the upper portion of the heat absorber 9 and has a relatively high temperature passes through the refrigerant upstream side of the lower portion of the heat absorber 9 and is sufficiently cooled before the first heat exchanger By being supplied to the two heat exchange air passages 15, the entire heat exchanger is cooled. As a result, the dehumidification performance can be improved.
また、空気吸込口２と、熱交換器４の天面より上方に配置された吸熱器９との間の第２の除湿経路２１ｂに、開閉装置２６を備える構成としてもよい。 Further, the opening/closing device 26 may be provided in the second dehumidifying path 21b between the air suction port 2 and the heat absorber 9 arranged above the top surface of the heat exchanger 4.
図４は、開閉装置２６が閉じた状態のときの図１内のＡ−Ａ断面における概略を示す断面図である。開閉装置２６が閉じると、第２の除湿経路２１ｂが閉鎖され、除湿経路２１は第１の除湿経路２１ａのみとなる。 FIG. 4 is a schematic cross-sectional view taken along the line AA in FIG. 1 when the opening/closing device 26 is closed. When the opening/closing device 26 is closed, the second dehumidification path 21b is closed, and the dehumidification path 21 is only the first dehumidification path 21a.
図４に示すように、開閉装置２６を設けることで、第１の除湿経路２１ａの風量および第１熱交換風路１４と第２熱交換風路１５のバランスを調整し、熱交換器４の熱交換量を最適化できる。結果として、熱交換器４を十分に冷却できるため、除湿性能を向上することができる。 As shown in FIG. 4, by providing the opening/closing device 26, the air volume of the first dehumidifying passage 21 a and the balance between the first heat exchange air passage 14 and the second heat exchange air passage 15 are adjusted, and the heat exchanger 4 of the heat exchanger 4 is adjusted. The amount of heat exchange can be optimized. As a result, the heat exchanger 4 can be sufficiently cooled, and the dehumidification performance can be improved.
また、本体ケース１に設けられた温度測定部２７と、温度測定部２７の測定温度によって開閉装置２６を制御する制御部２８とを備え、制御部２８は、測定温度が所定の温度以上で開閉装置２６を閉じる構成としてもよい。 Further, the temperature measuring unit 27 provided in the main body case 1 and the control unit 28 for controlling the switchgear 26 according to the measured temperature of the temperature measuring unit 27 are provided, and the control unit 28 opens and closes when the measured temperature is equal to or higher than a predetermined temperature. The device 26 may be closed.
本体ケース１外の温度が上昇して、空気吸込口２から本体ケース１内に流入する空気の水分量が増加すると、吸熱器９の冷媒蒸発が促進され、気化領域が増加する。すると、熱交換器４に十分に冷却されていない空気が通過することとなる。開閉装置２６を閉じることによって、第２の除湿経路２１ｂを閉鎖し、吸熱器９の風量を低下させ、吸熱器９が必要以上に温度上昇することを防ぐことができる。結果として、熱交換器４を十分に冷却できるため、除湿性能を向上することができる。 When the temperature outside the main body case 1 rises and the amount of water in the air flowing into the main body case 1 from the air suction port 2 increases, the evaporation of the refrigerant in the heat absorber 9 is promoted and the vaporization area increases. Then, the air that has not been sufficiently cooled passes through the heat exchanger 4. By closing the opening/closing device 26, it is possible to close the second dehumidifying path 21b, reduce the air volume of the heat absorber 9, and prevent the temperature of the heat absorber 9 from rising more than necessary. As a result, the heat exchanger 4 can be sufficiently cooled, and the dehumidification performance can be improved.
