Description

【0001】
【発明の属する技術分野】
本発明は、外気を室内へ導入する際、導入する外気の脱臭清浄化を図るとともに所用の空調と換気を行なう、外気脱臭装置に関する。
【0002】
【従来の技術】
外気処理システムとしては、例えば、特開平5−115737号公報や特開平7−120021号公報に開示されているように、湿気吸着性及び臭気吸着性を有する吸着剤を塗布したデシカントロータを用いて、調温、調湿、脱臭及び換気を行なう空気調和装置が使用されている。
【0003】
上記デシカント空気調和システムは、産業用、業務用の除湿システムや外気処理システムとして利用されている。その使用例としては電池・ガラス・メータ工場等の恒温恒湿空調システムや、物販店・パチンコ店・老人健康施設等の外気処理システムや人工スノーボードの除湿システム等があるが、最近ではスーパーマーケットで多く利用されている。
上記デシカント空調機は、回転式の除湿ロータ、顕熱ロータと、加熱コイル等で構成され、例えば処理される外気は除湿ロータの通過時に外気中の水分を吸着させることにより除湿を行なわせて高温低湿の空気にさせ、ついで、顕熱ロータの通過時で顕熱冷却をさせ、中温低湿空気となし室内に送出するようにしてある。
なお、除湿ロータの吸着性の再生のため処理空気と顕熱交換させた空気を再生熱源に使用し、再生ヒータで加熱して前記除湿ロータを乾燥させている。
【0004】
前記デシカント空調機の場合は、吸着による導入外気の除湿調整が過冷却して再熱する代わりに直接処理出来るため、従来の方法に比較して過冷却再熱のエネルギが不要となり、省エネが図られる点より前記外気処理システムとして多用されている。
【0005】
また、住宅等の居住域の空調方式には、空気調和機が使用され、冷水、温水、蒸気を使用して、取り入れた外気の冷却・減湿、加熱・加湿を行なっている。
また、店舗等の空調方式としては、フィルタ、冷却コイル、熱回収コイル、補助ヒータコイルの順に配設して外気の取り入れを行なっている。
【0006】
そして、従来より、空気中の脱臭処理は、空気中の臭気を吸着剤によって吸着させ脱臭する手段を備えた空気清浄器が使用されている。この種の清浄器においては空気導入側よりプレフィルタ、集塵フィルタ、脱臭フィルタの順に配設し、プレフィルタで大きな粉塵を除去した後、集塵フィルタで約μmオーダの粒子を取出し、そのあと脱臭フィルタで煙草の煙等有害物質を吸着除去をし、新鮮になった空気を適度な空調を行った後、室内へ送り室内の換気を行なっている。
【0007】
また、脱臭装置としては、脱臭目的だけのフィルタユニットが多く使用されているが、この場合下記問題点を内蔵している。
a、外気条件による性能のバラツキがある。則ち、
外気温度が低温度では効果が高いが、40℃以上では吸着能力が低下する。
b、脱臭フィルタは、外気から塵埃を吸い込むことによりその寿命が短くなる。
c、散水式は、水循環型が一般的で水質管理にコストが掛かる。
d、脱臭装置と空調装置が分離していて設備面積が増大する。
e、加熱装置と冷却装置が同一システムにある場合、別熱源を使用している。
【0008】
なお、脱臭方法として、悪臭成分を燃焼で分解する燃焼方法、酸化剤を使用する酸化方法、悪臭分を洗浄する薬液処理、芳香成分の発散により防臭をするマスキング法、中和剤処理方法等があるが、その他に脱臭手段として下記手段がある。
f、冷却、凝集を利用する方法で、冷却により霧化、液化させ脱臭効果をあげる。
g、溶媒を利用する方法で、水・溶剤等の噴霧により、悪臭成分を溶け込ませ脱臭効果をあげる。
h、マイナスイオンによる脱臭、除菌効果をあげる。
【0009】
【発明が解決しようとする課題】
則ち、従来使用されている脱臭手段は単独では前記した方法があり、外気処理手段としては前記したデシカント空調機による方法が、ランニングコストの低減及び省エネの観点より多用されているがこれは除湿が主目的で、脱臭と空調を効率的に組み合わせたものは無いという状況である。
【0010】
本発明は、上記問題点に鑑みなされたもので、外気の導入に際して、前記脱臭手段と空調ユニットの冷温熱の供給手段を組合せ、効率的な外気脱臭装置の提供を目的とするものである。

【0015】
そして、前記除塵手段を形成する水噴霧式ミストスプレー式には、ノズルから水を噴霧させ除塵させる方法で、噴霧水を少なくしてビニロックと称する濾材のようなエリミネータに水を噴霧させる方法がある。この場合噴霧水はドレーンに流す。
なお、ユニットの側板に小型のブースタポンプを設け、噴霧水を細かくする場合は導入空気との接触面積を増やし、下記効果をもたらす。
a、水溶性の悪臭物質や悪臭ガスの除去が可能となる。
b、塵埃の略完全な除去が可能となり、その結果脱臭フィルタの寿命が飛躍的に延びる。
c、導入直後の外気温度が水温より高いときは水噴霧により冷却効果を併せて上げることができる。
d、前記水噴霧を激しく行なわせ、マイナスイオンを発生させて、該マイナスイオンにより空気中に漂う菌やウイルス、悪臭成分の分子を水等に分解無害化できる。
【0016】

【0017】
前記冷却・除湿においては、冷却により悪臭成分の霧化、液化による脱臭が行なわれる。
【0018】
前記冷却・除湿、加熱・加湿手段における冷熱源と温熱源を、同一熱源機による凝縮熱と蒸発潜熱を使用する構成により省エネ効果を上げることができる。
【0019】
また、本発明の外気脱臭装置のパネル構造は、
前記前処理手段と脱臭手段と送風機とを内蔵一体化するとともに、断熱構造に構成するのが好ましい。
【0020】
前記発明は、本発明の外気脱臭装置を構成する、プレフィルタと水噴霧式除塵方式を形成するミストスプレー式とエリミネータとよりなる除塵手段と、冷却・除湿、加熱・加湿手段と脱臭手段と送風機とを一体化するコンパクト化したパネル構造に付き記載したもので、その構造は断熱パネルを使用するユニットよりなり、騒音の軽減化、結露防止を図る構成としたものである。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an outside air deodorization apparatus that, when introducing outside air into a room, deodorizes and cleans the outside air to be introduced and performs necessary air conditioning and ventilation.
[0002]
[Prior art]
As an outside air processing system, for example, as disclosed in JP-A-5-115737 and JP-A-7-120021, a desiccant rotor coated with an adsorbent having moisture adsorbability and odor adsorbability is used. Air conditioning devices that control temperature, humidity, deodorize and ventilate are used.
[0003]
The desiccant air conditioning system is used as an industrial or commercial dehumidification system or an outside air treatment system. Examples of its use include constant temperature and humidity air conditioning systems such as battery, glass and meter factories, outdoor air treatment systems such as merchandise stores, pachinko stores and health care facilities for the elderly, and dehumidification systems for artificial snowboards. It's being used.
The desiccant air conditioner includes a rotary dehumidification rotor, a sensible heat rotor, a heating coil, and the like. For example, the outside air to be treated is dehumidified by adsorbing moisture in the outside air when passing through the dehumidification rotor. It is made to be low-humidity air, then sensible heat-cooled when passing through the sensible heat rotor, and sent out into the room without medium-temperature low-humidity air.
Note that air that has been subjected to sensible heat exchange with processing air is used as a regeneration heat source for adsorptive regeneration of the dehumidification rotor, and the dehumidification rotor is dried by heating with a regeneration heater.
[0004]
In the case of the desiccant air conditioner, since the dehumidification adjustment of the introduced outside air by adsorption can be performed directly instead of supercooling and reheating, the energy of supercooling reheating is unnecessary compared with the conventional method, and energy saving is achieved. Therefore, it is widely used as the outside air processing system.
[0005]
In addition, air conditioners are used for air conditioning in residential areas such as houses, and cold water, hot water, and steam are used to cool / dehumidify the outside air taken in and heat / humidify it.
In addition, as an air conditioning system for a store or the like, outside air is taken in by arranging a filter, a cooling coil, a heat recovery coil, and an auxiliary heater coil in this order.
[0006]
Conventionally, an air purifier provided with a means for deodorizing a odor in the air by adsorbing the odor in the air with an adsorbent has been used. In this type of purifier, the pre-filter, dust collection filter, and deodorization filter are arranged in this order from the air introduction side, and after removing large dust with the pre-filter, particles of the order of about μm are taken out with the dust collection filter. The deodorizing filter adsorbs and removes harmful substances such as cigarette smoke, and after fresh air is moderately air-conditioned, it is sent indoors to ventilate the room.
[0007]
Moreover, as a deodorizing apparatus, many filter units only for the purpose of deodorizing are used, but in this case, the following problems are incorporated.
a, There is variation in performance due to outside air conditions. That is,
The effect is high when the outside air temperature is low, but the adsorbing capacity decreases when the temperature is 40 ° C. or higher.
b. The life of the deodorizing filter is shortened by sucking dust from the outside air.
c. The watering type is generally a water circulation type, and costs for water quality management are high.
d, The deodorizing device and the air conditioner are separated, and the facility area increases.
e. When the heating device and cooling device are in the same system, separate heat sources are used.
[0008]
In addition, as a deodorizing method, there are a combustion method that decomposes malodorous components by combustion, an oxidation method that uses an oxidizing agent, a chemical treatment that cleans malodorous components, a masking method that prevents deodorization by the release of aromatic components, a neutralizing agent treatment method, etc. In addition, there are the following means as other deodorizing means.
f, a method using cooling and agglomeration, which is atomized and liquefied by cooling to increase the deodorizing effect.
g. A method using a solvent that dissolves malodorous components by spraying water, solvent, etc., and improves the deodorizing effect.
h, Deodorizing and sterilizing effect due to negative ions.
[0009]
[Problems to be solved by the invention]
In other words, conventionally used deodorizing means has the above-described method alone, and the above-described desiccant air conditioner method is frequently used as an outside air treatment means from the viewpoint of reducing running costs and saving energy. However, there is no situation that effectively combines deodorization and air conditioning.
