【発明の属する技術分野】
本発明は、外気用空気清浄器を介して室内に外気を供給する給気路と、室内の空気を外部に排出する排気路とを備えた換気システム装置に関し、特に、高気密住宅におけるセントラル換気システム装置に関する。
【0002】
【従来の技術】
従来のこの種のセントラル換気システム装置としては、例えば、図5に示すように、外気用空気清浄器a及び熱交換機bを介して居室cに外気を供給する給気ダクトdと、居室cからホールeを経て便所・洗面所・浴室等のユーティリティルームfに流入した空気を熱交換機bを介して外部に排出する排出ダクトgとを備えたものが知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、かかる従来の換気システム装置においては、給気ダクトdから室内に給気される給気量と、排気ダクトgから排気される室内空気の排気量とが同じであるため、特に、高気密住宅等のように室内への外気給気量を多くして十分な換気を行う必要が有る場合には換気時間が長くなり、しかも、冷暖房時のエネルギーロスが多くなって室内冷暖房機(図示せず。)の運転時間が長くなるという不都合がある。
【0004】
本発明はかかる不都合を解消するためになされたものであり、短時間で室内の換気を十分に行うことができると共に、冷暖房時におけるエネルギーロスを少なくして室内冷暖房機の運転時間を短くするとができる換気システム装置を提供することを目的とする。
【0005】
なお、天井内には室内に外気を給気する給気ダクトdが配設されるため、ダクト工事と建築工事との取り合いが多くなってダクト経路の設定が複雑になり、しかも、下り天井が多くなってコスト高になるので、これらの問題についても解決することが望まれる。
【0006】
【課題を解決するための手段】
かかる目的を達成するために、請求項1に係る換気システム装置は、外気用空気清浄器を介して室内に外気を供給する給気路と、室内の空気を外部に排出する排気路と、室内の空気の一部を前記外気用空気清浄器より上流側の前記給気路に導いて該空気を室内に循環供給する循環路とを備えた換気システム装置において、前記給気路は、住宅の一方向に延びる複数本の一方向天井根太と、前記一方向天井根太と直交する方向に延びる複数本の直交方向天井根太とからなる天井枠組構造の上下面に張設された床材及び天井材とで構成される天井と、前記一方向天井根太、前記直交方向天井根太、前記床材及び前記天井材とで囲まれた空間同士を連通する、前記一方向天井根太の適宜箇所に設けられた送風口と、該送風口によって連通された空間に臨む天井材の適宜箇所に設けられた給気口と、一端が前記一方向天井根太の空間に、他端が屋外に配置された給気ダクトと、から構成され、前記排気路は、前記給気路上にない天井材の適宜箇所に設けられた第1の吸気口と、一端が前記第1の吸気口に、他端が屋外に配置された排気ダクトと、から構成され、前記循環路は、前記給気路上にない天井材の適宜箇所に設けられた第2の吸気口と、一端が前記第2の吸気口に、他端が前記外気用空気清浄器より上流側の前記給気ダクトに接続された循環ダクトと、から構成され、前記一方向天井根太の空間に配置された給気ダクトの給気口より空気を供給して前記給気路を介して室内に空気を供給するとともに、前記第1の吸気口にて室内空気を吸引して室内から空気の一部を排出する一方、前記第2の吸気口にて室内空気を吸引して室内の空気の一部を前記循環路に導いて該空気を室内に循環供給することを特徴とする。
【0007】
請求項2に係る住宅の天井の給気路構造は、住宅の一方向に延びる複数本の一方向天井根太と前記一方向天井根太と直交する方向に延びる複数本の直交方向天井根太とからなる天井枠組構造と、そ上下面に張設された床材及び天井材と、で構成される住宅の天井の給気路構造において、前記一方向天井根太、前記直交方向天井根太、前記床材及び前記天井材とで囲まれた空間同士を連通する、前記一方向天井根太の適宜箇所に設けられた送風口と、該送風口によって連通された空間に臨む天井材の適宜箇所に設けられた給気口と、を備え、前記一方向天井根太の空間に空気を供給して前記連通された空間を介して室内に空気を供給することを特徴とする

【発明の実施の形態】
以下、本発明の実施の形態を図を参照して説明する。図1は本発明の実施の形態の一例であるセントラル換気システム装置を説明するための説明的概念図、図2は図1の構成を立体的に示した説明的斜視図、図3は変形例を説明するための説明的概念図、図4R>4は本発明の他の態様の実施の形態であるセントラル換気システム装置を説明するための説明的概念図である。なお、この実施の形態では、2×4構造の高気密住宅で、室内を居室、ホール及び便所・洗面所・浴室等のユーティリティルームによって構成した場合を例に採るが、これに限定されるものではない。
0009
図1及び図2に示すように、このセントラル換気システム装置1は、室2内に外気を供給する給気ダクト3と、室2内の空気の一部を給気ダクト3に導いて該空気を居室8に循環供給する循環ダクト4と、ユーティリティルーム10の空気を外部に排出する排気ダクト5とを備える。
0010
給気ダクト3には、吸気口3aから導入された外気の汚れ(粉じん、花粉、臭気、VOC 等)を取り除く外気用空気清浄器6と、該外気用空気清浄器6より下流側で給気ダクト3を流れる空気と排気ダクト5を流れる空気との熱交換を行う熱交換機7とがそれぞれ介設されている。熱交換機7は天井内ふところに設置されている。また、外気用空気清浄器6より上流側の給気ダクト3には吸気口3aからの外気導入量を調整するボリュームダンパー(空気量調整手段)3cが介在され、熱交換機7より下流側の排気ダクト5には排気量を調整するボリュームダンパー5aが介在されている。給気ダクト3の給気口3bは、図2に示すように、建物の略中央部を居室8、ホール9及びユーティリティルーム10に沿って延びる天井根太11を臨む位置に配置されている。
0011
給気ダクト3の給気口3bから天井根太11に給気された空気の一部は、該天井根太11の幅方向の側壁に設けられた防火バンパー機能付送風口12を通って居室8の天井根太13に流入し、その後、居室8の天井14に設けられた給気口15から居室8に給気されるとともに、天井根太13に設けられた送風ダクト16を介して押入れ等に給気される。他の居室8及び押入れ等も同様にして給気口15及び送風ダクト16から給気される。そして、居室8に給気された空気は居室8の扉下部又は天井連通管等を介してホール9に流入し、ホール9に流入した空気は、一部が第2の吸気口9aを経て循環ダクト4に流入するとともに残部がユーティリティルーム10に流入する。ユーティリティルーム10に流入した空気は第1の吸気口10aを経て排気ダクト5に流入する。ここで、この実施の形態では、本発明の給気路を給気ダクト3及び天井根太11,13等の天井枠組構造部によって構成する
【0012
循環ダクト(循環路)4は、第2の吸気口9aから吸気されたホール9の空気を外気用空気清浄器6とボリュームダンパー3cとの間に位置する給気ダクト3に導くためのものであり、給気ダクト3に導かれたホール9の空気は給気ダクト3の吸気口3aから導入された外気と合流した後、外気用空気清浄器6及び熱交換機7を通って給気ダクト3の給気口3bから天井根太11,13及び送風ダクト16を介して居室8及び押入れ等にそれぞれ循環供給される。また、循環ダクト4には、ホール9の空気に含まれる炭酸ガスを検出するCO2
センサ17(空気成分検出手段)と、該CO2 センサ17より給気ダクト3側に配置されて循環ダクト4を流れる空気量を調整するボリュームダンパー(空気量調整手段)18とがそれぞれ介在されている。
0013
ボリュームダンパー18及び上述したボリュームダンパー3c,5aの制御は、CO2 センサ17によって得られた検出値に基づいて図示しないコントローラ(制御手段)が行うようになっている。コントローラは、CO2
センサ17によって得られた検出値が予め定められた規定値を越えた場合に居室8への循環空気量を少なくするか或いはゼロにして外気の割合を増やし、反対に規定値以下の場合には居室8への循環空気量を多くする(元に戻す)とともに、給気量、排気量、循環空気量を調整し、これにより、室全体の環境を清浄に保つと同時に給排気量(換気量)を必要最小限に保つことができるようにボリュームダンパー18、3c,5aをそれぞれコントロールする。
0014
排気ダクト(排気路)5は、第1の吸気口10aから吸気されたユーティリティルーム10の空気を熱交換機7を介して排気口10bから外部に排出するためのものである。なお、図1において符号19,20はそれぞれ熱交換機7内で給気ダクト3に介在された給気用ファン及び排気ダクト5に介在された排気用ファンであり、符号50は居室8の取り付けられた冷暖房機である。
0015
かかる構成の換気システム装置においては、循環ダクト4によってホール10の空気を給気ダクト3に導いて該給気ダクト3に取り入れられた外気と合流させ、該合流空気を外気用空気清浄器6を通過させてから給気ダクト3の給気口3bから天井根太11,13及び送風ダクト16を介して居室8及び押入れ等に給気するようにしているため、外気吸気量と排気量とを従来例と同一にした場合において、居室8への給気量を循環ダクト4によって給気ダクト3に導入されたホール9の空気分だけ増やすことができ、この結果、短時間で居室8、ホール9及びユーティリティルーム10の十分且つ均一な換気を行うことができる。
0016
また、冷暖房機50によって温められた空気又は冷やされた空気が循環ダクト4及び給気路(この実施の形態では、給気路を給気ダクト3及び天井根太11,13等の天井枠組構造部で構成する。)を介して居室8に循環供給されるようにしているため、冷暖房時におけるエネルギーロスを必要最小限に抑えることができ、この結果、冷暖房機50の運転時間を短くすることができ、更には換気量を最小限にコントロールすることによってもエネルギーロスを必要最小限に抑えることができる。
0017
更に、循環ダクト4を外気用空気清浄器6の上流側の給気ダクト3に接続するようにしているため、循環ダクト4を介して給気ダクト3に導かれたホール9の空気と給気ダクト3の吸気口3aから導入された外気との両方の空気の汚れを一台の外気空気清浄器6で除去することができ、この結果、設備コストの低減を図ることができる。
0018
更に、CO2 センサ17によって検出された室内空気の炭酸ガス検出値が規定値を越えた場合には、居室8に循環供給される空気量を少なくするか或いはゼロにするようにして外気の割合を増やし、反対に規定値以下の場合には居室8に循環供給される空気量を多くする(元に戻す)ようにしているので、健康的な室内環境を維持することができる。
0019
更に、天井根太11,13等の天井枠組構造部を給気路の一部としているため、従来のように、天井内の全てに給気ダクト3を配設する必要がなくなり、この結果、ダクト工事と建築工事との取り合いが少なくなって複雑なダクト経路の設定を不要にすることができるとともに、下り天井も少なくすることが可能になってコスト低減を図ることができる。
0020
なお、上記実施の形態では、CO2 センサ17を循環ダクト4に介在させて室内空気の炭酸ガスを検出するようにしているが、これに代えて、CO2
センサ17を居室8に設けて該居室8の空気に含まれる炭酸ガスを検出するようにしてもよい。
0021
また、上記実施の形態では、空気成分検出手段として、CO2 センサ17を用いた場合を例に採ったが、必ずしもこれに限定する必要はなく、例えば、煙、ほこり及び/又は臭い等を検出するセンサを用い、これらの検出値を基にコントローラによってボリュームダンパー18,3cを制御して循環空気量と外気量との割合を調整するようにしてもよい。
0022
更に、上記実施の形態では、給気ダクト3を流れる空気と排気ダクト5を流れる空気との熱交換を行う熱交換機7を設けた場合を例に採ったが、該熱交換機7を設けない場合においても本発明を適用することができる。
0023
更に、上記実施の形態では、給気ファン19及び排気ファン20を一台づつ設けているが、これに限定されず、例えば、給気ファン19及び排気ファン20をそれぞれ並列に二台或いはそれ以上設けて取入れ外気量(給気量)や排気量を調整するようにしてもよく、更には、給気ファン19及び排気ファン20の容量をそれぞれ変えることにより取入れ外気量(給気量)や排気量を調整するようにしてもよい。
0024
更に、図3に示すように、ボリュームダンパー30を給気ダクト3の熱交換機7の出口付近、給気ダクト3の居室8側の端部、循環ダクト4のホール9側の端部及び排気ダクト5のユーティリティルーム10側の端部にそれぞれ設け、各ボリュームダンパー30と上述したボリュームダンパー3c,5a,18をコントローラで制御することによって取入れ外気量、給気量及び排気量を調整するようにしてもよい。
0025
次に、図4を参照して本発明の他の態様の実施の形態である換気システム装置について説明する。なお、上記実施の形態と重複する部分については、図に同一符号を付してその説明を省略する。
0026
この換気システム装置40は、循環ダクト41によってホール9の空気を熱交換機7より下流側の給気ダクト3に導いてホール9の空気を居室8に循環供給するようにしたものであり、これにより、熱交換機7において給気ダクト3を流れる空気量と排気ダクト5を流れる空気量とが同等になって熱交換を効率良く行うことができる。循環ダクト41には、CO2
センサ17と、該CO2 センサ17の下流側に配置されて循環ダクト41を流れる空気の汚れを除去する循環用空気清浄器42と、循環用空気清浄器42より下流側に配置された循環用ファン43と、循環用ファン43より下流側に配置されたボリュームダンパー18とがそれぞれ介在されている。なお、その他の作用効果については循環用空気清浄器42と循環用ファン43が増える点以外は上記実施の形態とほぼ同一であるのでその説明を省略する。
0027
【発明の効果】
上記の説明から明らかなように、請求項1の発明によれば、循環路によって室内の空気の一部を給気路に導いて該給気路に取り入れられた外気と合流させ、該合流空気を外気用空気清浄器を通過させてから室内に給気するようにしているため、外気吸気量と排気量とを従来例と同一にした場合において、室内への給気量を循環路によって給気路に導かれた空気分だけ増やすことができ、この結果、短時間で室内の十分且つ均一な換気を行うことができるという効果が得られる。
0028
また、室内冷暖房機によって温められた空気又は冷やされた空気が循環路及び給気路を介して室内に循環供給されるため、冷暖房時におけるエネルギーロスを必要最小限に抑えることができ、この結果、室内冷暖房機の運転時間を短くすることができるという効果が得られる。

さらに、循環路を外気用空気清浄器より上流側の給気路に接続するようにしているため、該循環路を介して給気路に導かれた室内の空気と給気路に取り入れられた外気との両方の空気の汚れを一台の外気空気清浄器で除去することができ、この結果、設備コストの低減を図ることができるという効果が得られる

Further, since the circulation duct 4 is connected to the air supply duct 3 on the upstream side of the outside air cleaner 6, the air and the air in the hole 9 led to the air supply duct 3 through the circulation duct 4 are supplied. The dirt of both the air and the outside air introduced from the air inlet 3a of the duct 3 can be removed by the single outside air purifier 6. As a result, the equipment cost can be reduced.
[ 0018 ]
Furthermore, when the detected value of carbon dioxide in the indoor air detected by the CO 2 sensor 17 exceeds a specified value, the ratio of the outside air is set such that the amount of air circulated and supplied to the living room 8 is reduced or zero. On the other hand, when the amount is less than the specified value, the amount of air circulated and supplied to the living room 8 is increased (returned to the original value), so that a healthy indoor environment can be maintained.
[ 0019 ]
Further, since the ceiling frame structure portion such as the ceiling joists 11 and 13 is a part of the air supply path, it is not necessary to provide the air supply duct 3 in the entire ceiling as in the prior art. Since there is less interaction between construction and construction work, it is possible to eliminate the need for complicated duct route settings, and it is possible to reduce the number of descending ceilings, thereby reducing costs.
[ 0020 ]
Incidentally, in the above embodiment, the CO 2 sensor 17 is interposed in the circulation duct 4 and to detect the carbon dioxide in the room air, instead of this, CO 2
A sensor 17 may be provided in the living room 8 to detect carbon dioxide contained in the air of the living room 8.
[ 0021 ]
In the above embodiment, the case where the CO 2 sensor 17 is used as the air component detection means is taken as an example. However, the present invention is not necessarily limited to this. For example, smoke, dust and / or odors are detected. The volume dampers 18 and 3c may be controlled by a controller based on these detected values and the ratio between the circulating air amount and the outside air amount may be adjusted.
[ 0022 ]
Furthermore, although the case where the heat exchanger 7 that performs heat exchange between the air flowing through the air supply duct 3 and the air flowing through the exhaust duct 5 is provided as an example in the above-described embodiment, the heat exchanger 7 is not provided. The present invention can also be applied to.
[ 0023 ]
Furthermore, in the above-described embodiment, the air supply fan 19 and the exhaust fan 20 are provided one by one. However, the present invention is not limited to this. For example, the air supply fan 19 and the exhaust fan 20 are each two in parallel or more. It may be provided to adjust the intake outside air amount (supply amount) and the exhaust amount, and further, the intake air amount (supply amount) and the exhaust gas may be changed by changing the capacity of the supply fan 19 and the exhaust fan 20 respectively. The amount may be adjusted.
[ 0024 ]
Further, as shown in FIG. 3, the volume damper 30 is connected to the vicinity of the outlet of the heat exchanger 7 of the supply duct 3, the end of the supply duct 3 on the side of the living room 8, the end of the circulation duct 4 on the side of the hole 9, and the exhaust duct. 5 is provided at each end on the utility room 10 side, and each volume damper 30 and the above-described volume dampers 3c, 5a, and 18 are controlled by the controller so that the intake outside air amount, the air supply amount, and the exhaust amount are adjusted. Also good.
[ 0025 ]
Next, with reference to FIG. 4, the ventilation system apparatus which is embodiment of the other aspect of this invention is demonstrated. In addition, about the part which overlaps with the said embodiment, the same code | symbol is attached | subjected to a figure and the description is abbreviate | omitted.
[ 0026 ]
The ventilation system device 40 is configured such that the air in the hole 9 is guided to the air supply duct 3 on the downstream side of the heat exchanger 7 by the circulation duct 41 so that the air in the hole 9 is circulated and supplied to the living room 8. In the heat exchanger 7, the amount of air flowing through the air supply duct 3 and the amount of air flowing through the exhaust duct 5 become equal, and heat exchange can be performed efficiently. The circulation duct 41 includes CO 2
A sensor 17, a circulation air cleaner 42 disposed downstream of the CO 2 sensor 17 to remove dirt from the air flowing through the circulation duct 41, and a circulation air disposed downstream of the circulation air cleaner 42. A fan 43 and a volume damper 18 disposed downstream of the circulation fan 43 are interposed. The other effects are substantially the same as those in the above embodiment except that the circulation air purifier 42 and the circulation fan 43 are increased, and the description thereof is omitted.
[ 0027 ]
【The invention's effect】
As is apparent from the above description, according to the invention of claim 1, a part of the indoor air is guided to the air supply path by the circulation path and merged with the outside air taken into the air supply path, and the combined air Since the air is supplied to the room after passing through the outside air purifier, when the outside air intake amount and the exhaust amount are the same as in the conventional example, the indoor air supply amount is supplied by the circulation path. It is possible to increase the amount of air guided to the air passage, and as a result, it is possible to obtain sufficient and uniform ventilation in the room in a short time.
[ 0028 ]
In addition, since the air heated or cooled by the indoor air conditioner is circulated and supplied indoors through the circulation path and the air supply path, energy loss at the time of air conditioning can be minimized. The effect that the operation time of an indoor air conditioner can be shortened is acquired.
[ 0029 ]
Furthermore , since the circulation path is connected to the air supply path upstream from the outside air cleaner, the air is introduced into the indoor air and the air supply path led to the air supply path via the circulation path. Contamination of both the air and the outside air can be removed with a single outside air purifier, and as a result, the cost of equipment can be reduced .
[0030 ]
According to the invention of claim 2, since the the ceiling framework structure part of the air supply passage, as in the prior art, it is not necessary to dispose the air supply duct for all the ceiling, this result, the duct It is possible to reduce the cost between the construction and the construction work, thereby making it unnecessary to set a complicated duct route and reducing the descending ceiling.
