Description
住居、オフィス、工場、畜舎等を除加湿空調する。
除湿して、夏季の空調を行い、快適な環境を作ることが望まれているが除湿すると、従来の除湿装置では、消費電力が増加する。本件は除湿して消費電力を減少する空調装置に関する。Humidification and dehumidification of residences, offices, factories, barns, etc.
It is desired to perform dehumidification and air conditioning in summer to create a comfortable environment. However, when dehumidification is performed, power consumption increases in the conventional dehumidifier. This case relates to an air conditioner that dehumidifies to reduce power consumption.
最近の主な除湿方法は1.冷却除湿、2.乾式除湿方法、3.噴霧除湿方法。
4.湿式除湿方法等である。Recent major dehumidification methods are: 1. Cooling dehumidification 2. dry dehumidification method; Spray dehumidification method.
4). Wet dehumidification method and the like.
冷却除湿方法はエアコンと称していて、夏期に25℃で運転すると、冷房除湿を同時に作動する様に工夫されており、相対湿度が60%Rhになるようになっている。空気を一旦露点温度以下まで下げなければ除湿しないので、吹き出し温度を空調温度より、10℃以上さげているため、大きなエネルギーを必要している。
又、除湿モードで、運転すると、送風速度が遅くなり、室温は25℃以上に上昇する。また、25℃の冷房温度運転より、冷凍機がフル回転になるために消費電力が増大する。
冷却除湿は空調空気を露点温度以下に冷却して、結露させて除湿する。
一般的に使用しているエアコンは冷却除湿方式であり、25℃に設定運転をすると相対湿度が、60%RH前後又は以下になるように設計されており、快適環境になる。最近は環境庁より、省エネするために、夏季の空調温度を28℃に上げる様に要請があるが、28℃で運転すると、絶対水分量が上がり、快適環境にならないから、実行されていない場合が多い。The cooling and dehumidifying method is called an air conditioner, and when it is operated at 25 ° C. in summer, it is devised to operate the cooling and dehumidifying simultaneously, and the relative humidity is set to 60% Rh. Since dehumidification is not performed unless the air is once lowered below the dew point temperature, a large amount of energy is required because the blowing temperature is lowered by 10 ° C. or more from the air conditioning temperature.
In addition, when operated in the dehumidifying mode, the air blowing speed becomes slow and the room temperature rises to 25 ° C. or higher. In addition, the power consumption increases due to the full rotation of the refrigerator from the cooling temperature operation of 25 ° C.
Cooling dehumidification cools air-conditioning air below the dew point temperature and causes dew condensation to dehumidify.
The air conditioner generally used is a cooling and dehumidifying method, and when it is set to 25 ° C., the relative humidity is designed to be around 60% RH or below, and it becomes a comfortable environment. Recently, in order to save energy, the Environment Agency has requested that the air conditioning temperature in summer be raised to 28 ° C. However, if the operation is performed at 28 ° C, the absolute moisture content will increase and the comfortable environment will not be realized. There are many.
乾式除湿方法はシリカゲルに空気を接触させて、除湿する方法である。
この方法はシリカゲルに付着した水分を除く作業が不可欠であり、120℃以上の熱風でシリカゲルを再生しなければならない。
このためにシリカゲルへの加熱電力と、シリカゲルと接触した空気が加熱されるので、余熱を冷却するための電力が必要となる。
最近、稚内の珪藻土を利用し低温度での再生が報じられているが、除湿量が少ないので、未だ実用化されていない。The dry dehumidification method is a method of dehumidifying by bringing silica into contact with air.
In this method, it is essential to remove moisture adhering to the silica gel, and the silica gel must be regenerated with hot air of 120 ° C. or higher.
For this reason, the heating power to the silica gel and the air in contact with the silica gel are heated, so that power for cooling the residual heat is required.
Recently, it has been reported that diatomaceous earth in Wakkanai is used for regeneration at low temperatures, but it has not been put into practical use because of its low dehumidification amount.
噴霧除湿方法は露点室の中で露点温度以下に冷却した水を霧状に噴霧し空気を冷却して除湿を行う方法であるが、この方法は必ず再熱が必要になるので、環境試験機などの小型空間では有効であるが、住宅などの一般空調などには不向きである。 The spray dehumidification method is a method of spraying water cooled below the dew point temperature in the dew point chamber in the form of a mist and cooling the air to perform dehumidification. However, this method always requires reheating. It is effective in small spaces such as, but it is not suitable for general air conditioning in houses.
湿式除加湿方法は、塩化リチュームや塩化カルシュームを利用した湿式湿方法は温度が25℃〜30℃の範囲では大量の除湿効果ある省エネが可能であるが、塩化リチュームや塩化カルシュームの再生装置が必要なため、装置が大型化し、高額となる。また、塩化リチュームや塩化カルシュームの廃液処理が必要であるので、あまり普及していない。 Wet dehumidification / humidification methods can be energy-saving with a large amount of dehumidification effect in the range of temperatures between 25 ° C and 30 ° C, while wet dehumidification methods using chloride chloride or chloride chloride require a regeneration device for chloride chloride or chloride chloride. For this reason, the apparatus becomes large and expensive. Further, since waste liquid treatment of chloride chloride or calcium chloride is necessary, it is not very popular.
住居、オフィス、工場、畜舎等を空調する(以後一般空調と称する。)場合には温度調節は行われているが、湿度調節はほとんど行われていない。
その訳は湿度調節をすると、消費電力が増加するからである。本発明は湿度調節をして、空調の消エネを行う。
人が存在する居住空間には新鮮空気を導入しなければならないが、本発明は新鮮空気を必要としないか、減少して、空調の消エネを行う。In the case of air conditioning a house, office, factory, barn, etc. (hereinafter referred to as general air conditioning), the temperature is adjusted, but the humidity is hardly adjusted.
This is because power consumption increases when humidity is adjusted. In the present invention, the humidity is adjusted and the air conditioning is turned off.
Although fresh air must be introduced into a living space where people are present, the present invention does not require or reduces fresh air, thereby eliminating the energy of air conditioning.
外国の乾燥地帯では、気温30℃でも、相対湿度が低いので、快適に感じる。
恒温恒湿室にて体感試験して真意を確認する実験行った。エアコンの最適冷房温度は25℃運転時であった。室温30℃で、相対湿度が40%RHであればエアコン25℃運転とほとんど体感温度は同じであると50人中の45人の千葉大学工学部都市環境部の試験結果(論文。これからの空調)がある。
当方においても、確認のため、エアコンの25℃運転時と立体水面による室温30℃で相対湿度40%の比較試験を行った結果、どちらに入室しているか判らなくなるほどであった。In a dry region in foreign countries, even if the temperature is 30 ° C, the relative humidity is low, so it feels comfortable.
An experiment was conducted to confirm the true meaning by a sensation test in a constant temperature and humidity chamber. The optimum cooling temperature of the air conditioner was at 25 ° C operation. If the temperature is 30 ° C and the relative humidity is 40% RH, the temperature is almost the same as the air conditioner 25 ° C operation. There is.
For us, as a result of conducting a comparative test of 40% relative humidity at a room temperature of 30 ° C. when the air conditioner was operated at 25 ° C. for confirmation, it was difficult to know which one was in the room.
誰でも水で加湿することは知っていますが、水が除湿することあまり知られていません。
その実験状況を図3の恒温恒湿室を使用して、実験をします。
密閉した恒温恒湿室に水槽を作り、水を張り、水を冷却出来る様に冷却コイルを設置して、水の温度が調節冷却出来る様にします。
(実験 1)室温 30℃ 水温30℃(成り行き制御)にすると、相対湿度 100%RHになる。
(実験 2)室温 30℃ 水温25℃(冷却制御)にすると、 相対湿度 65%RHになる。
(実験 3)室温 30℃ 水温20℃(冷却制御)にすると、 相対湿度 40%RHになる。
以上の実験から、室内の温度が同じで、室内の空気と接触している水の水温が下がると相対湿度も下がり、冷却した水が除湿したことになる。又、水温が湿球温度と同じであることを発見した。Everyone knows that it will be humidified with water, but it is not well known that water dehumidifies.
The experiment will be conducted using the constant temperature and humidity chamber shown in Fig. 3.
A water tank is created in a sealed constant temperature and humidity chamber, water is added, and a cooling coil is installed so that the water can be cooled, so that the temperature of the water can be controlled and cooled.
(Experiment 1) Room temperature 30 ° C. When the water temperature is 30 ° C. (result control), the relative humidity becomes 100% RH.
(Experiment 2) Room temperature 30 ° C. When the water temperature is 25 ° C. (cooling control), the relative humidity becomes 65% RH.
(Experiment 3) When the room temperature is 30 ° C. and the water temperature is 20 ° C. (cooling control), the relative humidity becomes 40% RH.
From the above experiment, when the temperature of the water in contact with the room air is the same, the relative humidity is also lowered, and the cooled water is dehumidified. It was also discovered that the water temperature was the same as the wet bulb temperature.
本発明の立体水面の説明をします。不織布又はタオル布又の上部から水を流し布にしみこませ落下させて、垂直方向に水面をつくり、縦方向並列に多数ならべて、空調空気と接触させて、空調空気の湿度を制御する。(以下立体水面)と称す.
除湿する場合は水槽の水温を空気の湿球温度より低い温度以下に冷却した水を立体水面に流し、空調空気と接触させる。
加湿する場合は水槽の水温を空気の湿球温度より高い温度以上に加熱した水を立体水面に流し、空調空気と接触させる。I will explain the three-dimensional water surface of the present invention. Water is poured into the cloth from the upper part of the nonwoven fabric or towel cloth, and dropped to create a water surface in the vertical direction. The surface is arranged in parallel in the vertical direction and brought into contact with the conditioned air to control the humidity of the conditioned air. (Hereinafter referred to as three-dimensional water surface).
In the case of dehumidifying, water cooled to a temperature lower than the wet bulb temperature of air is flowed to the three-dimensional water surface and brought into contact with the conditioned air.
In the case of humidification, water heated to a temperature higher than the wet bulb temperature of air is flowed over the three-dimensional water surface and brought into contact with the conditioned air.
従来のエアコンでは、室温25℃運転の室内空気と吹き出し空気のエンタルピーは差12.3であり、本発明の立体水面による、温湿度で、30℃/40%RHにおける室内空気と吹き出し空気の差はエンタルピー5.9であるので、循環空気の消費エネルギーにおける省エネ率は52%の省エネが出来る。 In a conventional air conditioner, the enthalpy between room air and air blown at room temperature of 25 ° C. is 12.3, and the difference between room air and blown air at 30 ° C./40% RH in terms of temperature and humidity due to the three-dimensional water surface of the present invention. Since the enthalpy is 5.9, the energy saving rate in the energy consumption of the circulating air is 52%.
新鮮空気のエンタルピーは従来のアエコンのエンタルピー差は7.0であり、本発明の立体水面のエンタルピー差5.1であるので、消費エネルギーにおける省エネ率は新鮮空気による省エネは22.2%である。 As for the enthalpy of fresh air, the enthalpy difference of the conventional air-conditioner is 7.0, and the enthalpy difference of the three-dimensional water surface of the present invention is 5.1. Therefore, the energy saving rate in the energy consumption is 22.2%. .
空気中から除湿された直後の水は炭酸ガスが全く含まれていないので、空気と接触すると、水温が20℃以下であれば、炭酸ガスを除湿した水量とほぼ同じ体積の炭酸ガスを吸収する。この特徴により、一般空調に必要な新鮮空気の量を必要がないか、減量することが出来る。
新鮮空気の量を必要がないか、減量することが出来れば、新鮮空気による顕熱負荷及び潜熱負荷がさらに低下して、新鮮空気負荷は22.2%以下に省エネすることが出来る。Since the water immediately after dehumidification from the air does not contain any carbon dioxide, when it comes into contact with the air, if the water temperature is 20 ° C. or less, it absorbs carbon dioxide of the same volume as the amount of water dehumidified from carbon dioxide. . This feature makes it possible to reduce or reduce the amount of fresh air required for general air conditioning.
If the amount of fresh air is not required or can be reduced, the sensible heat load and latent heat load due to the fresh air can be further reduced, and the fresh air load can be saved to 22.2% or less.
