本発明の一実施例の有機溶剤を含む空気の熱交換方法及び有機溶剤を含む空気の熱交換装置を図面（図１及び図２）を参照して説明する。
図１に示すＤは有機溶剤を含む空気の熱交換装置で、有機溶剤を含む空気の熱交換装置Ｄは、室内で発生する有機溶剤の排出を良好にして、排出に伴う熱を、熱回収ユニットＵ内の全熱交換器１により、室内空気と室外空気を熱交換させて、回収することができるようにしたものである。 An air heat exchange method including an organic solvent and an air heat exchange apparatus including an organic solvent according to an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 and 2).
D shown in FIG. 1 is an air heat exchange device containing an organic solvent. The air heat exchange device D containing an organic solvent improves the discharge of the organic solvent generated indoors, and recovers the heat accompanying the discharge as a heat recovery device. The total heat exchanger 1 in the unit U exchanges heat between indoor air and outdoor air so that it can be recovered.

全熱交換器１は、図２に示すように、仕切部材１１と間隔保持部材１２とを交互に積層し、仕切部材１１の間の間隔保持部材１２によって間隔が保持された流路を形成し、隣接した一方の流路１３に室内空気を、隣接した他方の流路１４に室外空気を通過させ、仕切部材１１を介して室内空気と室外空気を熱交換するもので、仕切部材１１は、有機溶剤のガスを透過する性質を有するもので、例えば、有機溶剤のガスを透過する多孔体で形成されている。
より具体的に言えば、例えば、三菱電機株式会社製 商品名「ロスナイ（登録商標）」である。
図１に示すＯは室外を、Ｒは有機溶剤を使用する室内をそれぞれ示している。 As shown in FIG. 2, the total heat exchanger 1 is configured such that the partition members 11 and the spacing members 12 are alternately stacked to form a flow path in which the spacing is held by the spacing members 12 between the partition members 11. The indoor air is passed through the adjacent one flow path 13 and the outdoor air is passed through the other adjacent flow path 14 to exchange heat between the indoor air and the outdoor air via the partition member 11. It has the property of permeating the organic solvent gas, and is formed of, for example, a porous body that permeates the organic solvent gas.
More specifically, for example, trade name “Lossnai (registered trademark)” manufactured by Mitsubishi Electric Corporation.
In FIG. 1, O indicates the outdoor, and R indicates the room in which the organic solvent is used.

換気用通路２は、室内空気を全熱交換器１の一方の流路１３を介して室外へ案内するもので、換気用送風機３は、図１に示すように、室外側に位置し、換気用通路２内へ室内空気を取り入れ、室外へ送風するものである。そして、換気用送風機３の送風は、換気用送風機制御手段４により制御されるようになっている。なお、一方の流路１３は、換気用送風機３の吸い込み側に位置している。     The ventilation passage 2 guides indoor air to the outside through one flow path 13 of the total heat exchanger 1, and the ventilation fan 3 is located outside the room as shown in FIG. The room air is taken into the use passage 2 and is blown outside the room. The ventilation of the ventilation fan 3 is controlled by the ventilation fan control means 4. One flow path 13 is located on the suction side of the ventilation fan 3.

また、給気用通路５は、室外空気を全熱交換器１の他方の流路１４を介して室内へ案内するもので、給気用送風機６は、図１に示すように、室外側に位置し、給気用通路５内へ室外空気を取り入れ、室内へ送風するものである。そして、給気用送風機６の送風は、給気用送風機制御手段７により制御されるようになっている。なお、他方の流路１４は、給気用送風機６の吹き出し側に位置している。     The air supply passage 5 guides outdoor air into the room through the other flow path 14 of the total heat exchanger 1, and the air supply blower 6 is provided on the outdoor side as shown in FIG. It is located, takes outdoor air into the air supply passage 5 and blows it into the room. The air supply of the air supply fan 6 is controlled by the air supply fan control means 7. The other flow path 14 is located on the blowing side of the air supply fan 6.

上述した有機溶剤を含む空気の熱交換装置（有機溶剤を含む空気の熱交換方法）Ｄにあっては、給気用送風機制御手段７及び換気用送風機制御手段４により、給気用送風機６の吹き出し風量（例えば、３０５ＣＭＨ）を換気用送風機３の吸い込み風量（例えば、２９９ＣＭＨ）より多くするため、
つまり、風量が多い分、全熱交換器１の他方の流路１４を流れる室外空気の一部が仕切部材１１を介して全熱交換器１の一方の流路１３を流れる有機溶剤を含む空気に流れ込み（流れ込む風量Ｑは、例えば、５１ＣＭＨ）、
その結果、一方の流路１３を流れる有機溶剤を含む空気が仕切部材１１を介して全熱交換器１の他方の流路１４へ流入するのを抑制することができ、
有機溶剤の排出を良好にして、全熱交換器１の仕切部材１１を介して室内空気と室外空気とが熱交換して、熱回収をすることができる。 In the above-described air heat exchange device containing an organic solvent D (heat exchange method of air containing an organic solvent) D, the air supply fan 6 is controlled by the air supply blower control means 7 and the ventilation fan control means 4. In order to make the blowing air volume (for example, 305CMH) larger than the intake air volume (for example, 299CMH) of the ventilation fan 3,
That is, a part of the outdoor air that flows through the other flow path 14 of the total heat exchanger 1 includes an organic solvent that flows through the one flow path 13 of the total heat exchanger 1 through the partition member 11 because the air volume is large. (Air flow rate Q is, for example, 51CMH),
As a result, it is possible to suppress the air containing the organic solvent flowing through one flow path 13 from flowing into the other flow path 14 of the total heat exchanger 1 through the partition member 11.
The organic solvent can be discharged well, and the heat can be recovered by exchanging heat between the indoor air and the outdoor air via the partition member 11 of the total heat exchanger 1.

即ち、仕切部材１１は、水蒸気は透過するが、有機溶剤のガスを含んだ空気は透過しにくい透湿膜で形成されている。
なお、仕切部材１１は、三菱電機株式会社製 商品名「ロスナイ（登録商標）」に使用されているもので、紙または不織布に、親水性がありながら水に不溶性のセルロース膜を形成したものである。
つまり、給気と排気の全熱（温度＋湿度）交換は仕切部材１１の透湿膜を介して行われ、この透湿膜の特性は、水蒸気は良く透過するが、有機溶剤のガスを含んだ空気は透過しにくいものである。
そのため、例えば、給気用送風機６の吹き出し風量を換気用送風機３の吸い込み風量と略同じとすれば、仕切部材１１の透湿膜を介して排気側の有機溶剤のガスを含んだ空気が給気側に流れ込む不都合が生じるが、
この実施例の有機溶剤を含む空気の熱交換方法（有機溶剤を含む空気の熱交換装置Ｄ）によれば、給気用送風機制御手段７及び換気用送風機制御手段４により、給気用送風機６の吹き出し風量を換気用送風機３の吸い込み風量より多くするため、
つまり、風量が多い分、全熱交換器１の他方の流路１４を流れる室外空気の一部が仕切部材１１を介して全熱交換器１の一方の流路１３を流れる有機溶剤を含む空気に流れ込み、
その結果、一方の流路１３を流れる有機溶剤を含む空気が仕切部材１１を介して全熱交換器１の他方の流路１４へ流入するのを抑制することができ、
有機溶剤の排出を良好にして、全熱交換器１の仕切部材１１を介して室内空気と室外空気とが熱交換して、熱回収をすることができる。 That is, the partition member 11 is formed of a moisture permeable film that allows water vapor to pass therethrough but hardly contains air containing an organic solvent gas.
The partition member 11 is used in the trade name “Lossnai (registered trademark)” manufactured by Mitsubishi Electric Corporation, and is formed by forming a hydrophilic but water-insoluble cellulose film on paper or non-woven fabric. is there.
In other words, the total heat (temperature + humidity) exchange between the supply air and the exhaust gas is performed through the moisture permeable membrane of the partition member 11. The moisture permeable membrane has a characteristic that water vapor permeates well but contains an organic solvent gas. Air is difficult to permeate.
Therefore, for example, if the blown air volume of the air supply fan 6 is substantially the same as the intake air volume of the ventilation fan 3, air containing the organic solvent gas on the exhaust side is supplied through the moisture permeable membrane of the partition member 11. The inconvenience of flowing into the air side occurs,
According to the heat exchange method for air containing an organic solvent in this embodiment (heat exchange device D for air containing an organic solvent), the supply fan 6 is supplied by the supply fan control means 7 and the ventilation fan control means 4. In order to make the blown air volume of the air larger than the intake air volume of the ventilation fan 3,
That is, a part of the outdoor air that flows through the other flow path 14 of the total heat exchanger 1 includes an organic solvent that flows through the one flow path 13 of the total heat exchanger 1 through the partition member 11 because the air volume is large. Flow into
As a result, it is possible to suppress the air containing the organic solvent flowing through one flow path 13 from flowing into the other flow path 14 of the total heat exchanger 1 through the partition member 11.
The organic solvent can be discharged well, and the heat can be recovered by exchanging heat between the indoor air and the outdoor air via the partition member 11 of the total heat exchanger 1.

なお、実験結果を示せば、測点１の風量は２４８ＣＭＨ、測点２の風量は２９９ＣＭＨ、測点３の風量は３０５ＣＭＨ、測点４の風量は２５４ＣＭＨであった。他方の流路１４を流れる室外空気の風量の３０５ＣＭＨの内、５１ＣＭＨの室外空気の風量が仕切部材１１を介して一方の流路１３を流れる有機溶剤を含む空気に混入したことになる。
また、図３のグラフから明らかなように、揮発性有機化合物（ＶＯＣ）の濃度が希釈されている。これは、他方の流路１４の室外空気の一部が仕切部材１１を介して一方の流路１３に流入しているからである。
また、図４のグラフから明らかなように、測点４における揮発性有機化合物（ＶＯＣ）の濃度に変化がない。
これは、一方の流路１３の室内空気の一部が仕切部材１１を介して他方の流路１４の室外空気に流入していないからである。
また、図５及び図６のグラフから明らかなように、仕切部材１１を介して室内空気と室外空気とが熱交換し、熱回収が良好に行われている。 As shown in the experimental results, the air volume at station 1 was 248 CMH, the air volume at station 2 was 299 CMH, the air volume at station 3 was 305 CMH, and the air volume at station 4 was 254 CMH. Of the 305 CMH of the outdoor air volume flowing through the other flow path 14, 51 CMH of the outdoor air volume is mixed into the air containing the organic solvent flowing through the one flow path 13 via the partition member 11.
Further, as apparent from the graph of FIG. 3, the concentration of the volatile organic compound (VOC) is diluted. This is because part of the outdoor air in the other channel 14 flows into the one channel 13 via the partition member 11.
Further, as is apparent from the graph of FIG. 4, there is no change in the concentration of the volatile organic compound (VOC) at the measurement point 4.
This is because part of the indoor air in one flow path 13 does not flow into the outdoor air in the other flow path 14 via the partition member 11.
Further, as is apparent from the graphs of FIGS. 5 and 6, the indoor air and the outdoor air exchange heat through the partition member 11, and heat recovery is performed favorably.
