換気用熱交換器に関する。[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a heat exchanger suitably used in ventilation systems of houses, etc., and more specifically, the present invention relates to a heat exchanger that is suitably used in ventilation systems of houses, etc. The present invention relates to a heat exchanger for ventilation that has both sensible heat without heat transfer and total heat that allows the movement of water vapor.
「従来技術とその課題」
近年、一般住宅においてもその構築法なとか非常に進歩
したことから、住宅内の気密性か極めて高（なっている
。ところか、このように気密性が高くなっていることか
ら、特に冬季においてはストーブの使用や人間の呼吸な
とによって室内の空気か汚れることにより、その空調に
あたっては換気を行うことが必須となっている。しかし
、このような冬季の場合、換気を行うにあたっては当然
家内の温度コントロールを兼ねなくてはならず、したが
って単に外気を取り入れるだけでなく、取り入れた外気
を暖めて給気する必要かある。``Prior art and its issues'' In recent years, the construction methods of ordinary houses have made great progress, and the airtightness inside the house has become extremely high. Especially in winter, indoor air becomes polluted due to the use of stoves and human breathing, making it essential to provide ventilation when air conditioning. When ventilating, it is of course necessary to control the temperature inside the house, so it is not only necessary to simply bring in outside air, but also to warm the outside air before supplying it.
このように外気を暖める場合には、単に取り入れた外気
をヒーターなとで加熱してもよいか、それてはエネルキ
ー的にみてロスか多く、空調運転コストが大きくなるた
め、近年では、外気を予め室内からの暖められた空気の
排気性と熱交換し、その後必要に応じて加熱することな
どにより、低コストで十分暖められた新鮮な空気を室内
に取り入れることかなされている。When heating outside air in this way, is it possible to simply heat the outside air taken in with a heater?This results in a lot of energy loss and increases air conditioning operating costs. It is possible to bring sufficiently warm fresh air into a room at a low cost by exchanging heat with the exhausted air that has been warmed from the room in advance, and then heating it as necessary.
ところで、熱交換を行うにあたって用いられる熱交換器
には、一般に顕熱型と全熱型との二種類が知られている
。By the way, there are generally two types of heat exchangers used for heat exchange: a sensible heat type and a total heat type.
顕熱型のものは、単に流体なとの熱媒間において熱交換
のみを行うものであり、熱交換を行うための伝熱面か、
例えば金属や樹脂なとの気体をも透過しない材料によっ
て構成されたものである。Sensible heat type ones simply exchange heat between a fluid and a heat medium, and either a heat transfer surface for heat exchange or
For example, it is made of a material such as metal or resin that does not allow gas to pass through.
一方全熱型のものは、熱交換を行うとともに物質の移動
、例えば水蒸気の移動を伴うものである。On the other hand, the total heat type performs heat exchange and also involves the movement of substances, such as water vapor.
そして、その伝熱面には、従来不織布や紙（和紙）なと
の水蒸気等を透過する材料に化学的処理を施して強度を
高めたものを用い、水蒸気の透過による移動や水分の毛
細管現象による移動を可能にしている。For the heat transfer surface, conventional materials such as non-woven fabrics and paper (Japanese paper) that are permeable to water vapor, etc., are chemically treated to increase their strength. This allows for movement.
そして、顕熱型のものは、金属や樹脂などの気体をも透
過しない材料によって構成されていることから冬季なと
において生じる凍結には強いものの、単に熱交換のみを
行うことから、高温側および低温側の熱媒体が共に空気
である場合、空気中に含まれる湿気、すなわち水蒸気の
移動かなく伝熱によってのみ熱交換かされることにより
、熱量の移動か少なくよって熱交換効率か必ずしも十分
とはいえない。Sensible heat type types are made of materials such as metals and resins that are impermeable to gases, so they are resistant to freezing that occurs in winter, but since they only perform heat exchange, they When the heat medium on the low-temperature side is air, heat exchange is performed only by heat transfer without the movement of moisture contained in the air, that is, water vapor, so the heat exchange efficiency is not always sufficient depending on whether the amount of heat is transferred or not. No, no.
これに対して全熱型のものは、熱媒体か共に空気の場合
、湿気の移動を伴って熱交換かなされるため、伝熱によ
って移動する熱とともに通常は熱容量の大きい水蒸気も
低温側の熱媒体に移動することから、顕熱型に比へ熱交
換率か高いものとなっている。しかし、この全熱型の換
気用熱交換器ζこあっても、不織布や和紙なとに化学的
処理を施したものを伝熱面として用いているため、例え
ば寒冷地て使用する場合には外気か氷点下になることか
多いことから、熱交換後伝熱面を透過して排気側より給
気側（外気側）に流入した湿気（水蒸気）が冷却されて
凝縮（結露）し、さらにこれか凍結するといった問題か
ある。そして、これによりこの全熱型のものにあっては
、その材質上機械的強度に劣るため、このような凍結に
起因して破損が生し易く、よってその使用が困難てあり
、実際には寒冷地などでは使用しないのが普通である。On the other hand, in an all-heat type, when air is used as the heat medium, heat is exchanged with the movement of moisture, so in addition to the heat transferred by heat transfer, water vapor, which has a large heat capacity, is also used to generate heat on the low-temperature side. Since the heat is transferred to the medium, the heat exchange rate is higher than that of the sensible heat type. However, even with this all-heat type ventilation heat exchanger, chemically treated non-woven fabric or Japanese paper is used as the heat transfer surface, so for example, when used in cold regions, Since the temperature of the outside air is often below freezing, the moisture (water vapor) that passes through the heat transfer surface after heat exchange and flows from the exhaust side to the supply air side (outside air side) is cooled and condenses (condensation). There are also problems such as freezing. As a result, this all-heating type has inferior mechanical strength due to its material, so it is prone to breakage due to such freezing, making it difficult to use. It is usually not used in cold regions.
このように従来のものでは、顕熱型、全熱型ともに一長
一短があり、その両方の長所を兼ね備えたものかないの
か実状であることから、これら顕熱型および全熱型の機
能を備えた熱交換器の提供が望まれている。In this way, conventional heat sinks have advantages and disadvantages for both sensible heat type and total heat type, and the reality is that there is no one that has the advantages of both. The provision of exchangers is desired.

貼設されている。The exhaust heat exchanger plate 2a is made of hard synthetic resin such as polyethylene as shown in FIG. It consists of a pair of arranged square plates 3, 3 and a plurality of partition plates 5 provided between them to form a plurality of parallel passages 4b between these square plates 3, 3. be. Here, the passage 4a is a passage through which exhaust gas sent from the indoor side passes. Further, in the exhaust heat exchanger plate 2a, a large number of through holes 6a are formed in each of the square plates 3, 3 to allow communication between the outer surface side and the passage 4a. As will be described later, these through holes 6a communicate with the through holes of the overlapping air supply heat exchanger frames 1-2b via the porous membranes on their outer surfaces. As will be described later, these through-holes 6a are densely arranged at locations on the exhaust side of the supply air heat exchanger plate 2b and on the inlet side of the exhaust heat exchanger plate 2a, However, it is not disposed on the inlet side of the air supply heat exchanger plate 1-2b, but on the exhaust side of the exhaust heat exchanger plate. because,
These through holes 6a serve as passages for moisture (water vapor) to pass through, as will be described later. As the air exhausted from the air is cooled, there is a high possibility that the moisture (water vapor) will also cool and condense (condensation), especially in cold regions, where there is a risk of condensation or even freezing. Therefore, if the heat exchange in this part is not a total heat type but a sensible heat type, problems associated with condensation and freezing of water vapor can be prevented. Furthermore, porous membranes 7.7 are pasted on the entire surface of the square plates 3.3 of the heat exchanger plate 2a, covering the through holes 6a.

となり、よって室内が十分に加温される。In order to ventilate the room using the system as described above, the blower 12 is driven to send indoor air to the heat exchanger 1, and the blower 14 is also driven to send outside air to the heat exchanger 1. Then, the indoor dirty air (exhaust air) is transferred to heat exchanger 1.
, while fresh outside air flows into the heat exchanger j
flows into the passage 4b. Then, these exhaust air and outside air are transferred to the heat exchanger plate 2a in the heat exchanger 1.
Heat is exchanged by conduction through the square plate 3 of 2b..., and when the indoor humidity is high such as in winter, the humidity (water vapor) in the exhaust gas or the through hole 6a, porous @7, through hole 6b and moves into the outside air. In this way, the heat exchanger 1 not only exchanges heat by conduction, but also
Since total heat type heat exchange is performed with the movement of water vapor, the air supplied into the room from the fourth tact 11 receives the heat of the water vapor and is heated with a high heat exchange rate. The room is sufficiently heated.

Air conditioning operating costs can be reduced. Also,
The through-holes 6a and 6b are not provided at a location that is the inlet side of the air supply heat exchanger plate 2b and the exhaust side of the exhaust heat exchanger plate, so that heat exchange at this location is performed as sensible heat. By making it into a mold, even if it is used in a particularly cold region, the air exhausted from the room will be cooled the most, and the moisture (
Since there is no movement of water vapor in the above-mentioned areas where there is a high possibility of condensation (condensation) and freezing due to cooling, inconveniences such as overloading of the blower due to condensation and freezing of water vapor can be prevented. I can do it.

In that case, these through holes 6. Since the amount of water vapor passing through a and 6b is small, the heat exchange at these locations is close to the sensible heat type.

かできる。"Effects of the Invention" As explained above, the ventilation heat exchanger of the present invention enables sensible heat exchange or similar heat exchange in locations where through holes are sparsely arranged or are not arranged. Since it is possible to perform total heat type heat exchange in closely spaced locations, it is possible to perform total heat type heat exchange with the movement of water vapor in locations with densely arranged through holes. Since heat exchange can be performed efficiently, air conditioning operating costs can be reduced in terms of energy. In addition, since the through-holes are arranged sparsely or not at a location that is the inlet side of the supply air heat exchanger plate and the exhaust side of the exhaust heat exchanger plate, heat exchange at this location is noticeable. It is a thermal type or something close to it, so even if it is used in a cold region, the air exhausted from the room will be the coolest, and the moisture (water vapor) will be cooled and condensed (condensed) and frozen. The movement of water vapor at the above-mentioned locations where there is a high possibility of movement is eliminated or reduced, and therefore, inconveniences associated with condensation and freezing of water vapor, such as overloading the blower, can be prevented.
