Abstract
Description
具体的には、図18に示されるように、調湿装置のケーシング111の内部には、空気流を生成するファン134,135や、冷媒を循環させる冷媒回路が設けられている。冷媒回路は、吸着剤が担持された2つの吸着熱交換器131,132、圧縮機127、膨張弁、四路切換弁等を冷媒配管で接続してなる。ケーシングの一側面121(以下、第1側面という)には、室外空気を取り入れるための外気取入口151と、室内空気を取り入れるための内気取入口153とが形成され、その近傍にはエアフィルタ171が設けられている。また、第1側面121の両側に隣接する他の2側面122,123(以下、第2,第3側面という)には、当該室外空気を室内へ供給するための給気吹出口154と、当該室内空気を室外へ排出するための排気吹出口152とがそれぞれ形成されている。
また、ケーシング111内のファン134,135やエアフィルタ171、電装品ユニット等は、点検や部品交換、清掃等のメンテナンスが必要であり、これらのメンテナンスは、天井に形成された開口を介して天井裏で行われる。
しかし、天井裏におけるメンテナンスは、狭く暗い場所での作業となるため非常に煩雑である。また、電装品ユニット及びファン134,135と、エアフィルタ171とは離れて配置されているので、ケーシング111の周囲には、それぞれの作業スペースを分散して確保しなければならず、一箇所でメンテナンスを行うことができない。また、作業スペースを分散して確保するために調湿装置の設置場所の制約が大きくなるという欠点もある。
ケーシングと、
前記吸着熱交換器、冷媒を循環させる圧縮機、冷媒の循環方向を切り換える切換機構、及びこれらを接続する冷媒配管を有している冷媒回路と、
前記ケーシング内に室外空気及び室内空気をそれぞれ取り入れるファンと、
当該調湿装置の制御部品を含む電装品ユニットと、を備え、
前記ケーシングが、前記ファン、前記切換機構、及び前記電装品ユニットが配置された第1ケーシングと、
前記吸着熱交換器が配置された第2ケーシングと、からなり、
前記第1ケーシングと前記第2ケーシングとがダクトを介して相互に接続されていることを特徴とする。
前記第2ケーシングに、室外空気を取り入れるための外気取入口、及び室内空気を取り入れるための内気取入口が形成されていてもよい。
あるいは、前記第1ケーシングに、室外空気を取り入れるための外気取入口、及び室内空気を取り入れるための内気取入口が形成され、
前記第2ケーシングに、室内へ空気を供給するための給気吹出口、及び室外へ空気を排出するための排気吹出口が形成されていてもよい。
この場合、比較的メンテナンス頻度の高い部品であるエアフィルタのメンテナンス性を向上させることができる。
あるいは、前記ダクトは、前記外気取入口から前記第1ケーシング内に取り入れられた室外空気を前記第2ケーシング内へ導入させる外気用ダクトと、前記内気取入口から前記第1ケーシング内に取り入れられた室内空気を前記第2ケーシング内へ導入させる内気用ダクトとを含むことができる。
いずれにおいても、音の発生する圧縮機を、第1ケーシングとともに室外に配置することができる。
この構成によれば、複数の部屋に対してそれぞれ第2ユニットを配置し、各第2ユニット内の吸着熱交換器に対する冷媒の供給を、1つの第1ユニットにおける圧縮機等を用いて行うことができる。
<第1の実施の形態>
図1は、本発明の第1の実施の形態に係る調湿装置の内部の平面説明図である。図2は、図1におけるA-A線矢視方向から見た調湿装置の内部の説明図である。図3は、図1におけるB-B線矢視方向から見た調湿装置の内部の説明図である。
本実施の形態の調湿装置10は、室内の換気を行いながら除湿又は加湿を行うものであり、ケーシング11A,11Bと、冷媒回路12と、空気流制御機構13等を備えている。
冷媒回路12は、第1熱交換器31、四路切換弁(切換機構)26、圧縮機27、第2熱交換器32、及び電動膨張弁(膨張機構)28を冷媒配管29によって接続してなり、冷媒を循環させることによって蒸気圧縮式の冷凍サイクルを実行するように構成されている。
圧縮機27は、その吐出側が四路切換弁26の第1のポートに接続され、その吸入側が四路切換弁26の第2のポートに接続されている。第1熱交換器31の一端は、四路切換弁26の第3のポートに接続されている。第1熱交換器31の他端は、電動膨張弁28に接続されている。第2熱交換器32の一端は、四路切換弁26の第4のポートに接続されている。第2熱交換器32の他端は、電動膨張弁28に接続されている。
第1熱交換器31及び第2熱交換器32は、いずれも、伝熱管と多数のフィンとを備えた、いわゆるクロスフィン型のフィン・アンド・チューブ式熱交換器により構成されている。また、第1熱交換器31及び第2熱交換器32の外表面には、その概ね全面に亘ってゼオライト等の吸着剤が担持されている。
なお、図1に示されるように、外気取入口51から第2ケーシング11B内に取り入れられる空気をOA、内気取入口53から第2ケーシング11B内に取り入れられる空気をRA、排気吹出口52から第1ケーシング11A外へ排出される空気をEA、給気吹出口54から第1ケーシング11A外へ排出される空気をSAと表記することがある。
図3に示されるように、第2空気流通路60は、第7区画壁67によって上下2段に区画されている。第7側板24c(図1参照)に形成された第2中継吹出口23aは、上段側の第2空気流通路60aに連通している。また、内気取入口53は、下段側の第2空気流通路60bに連通している。
図2に示されるように、第2ケーシング11Bの第3区画壁63には、4つの通気口81~84が前後上下に並べて形成されている。これらの通気口81~84は、それぞれダンパ41~44によって開閉可能に構成されている。
また、図3に示されるように、第4区画壁64には、4つの通気口85~88が前後上下に並べて形成されている。これらの通気口85~88は、それぞれダンパ45~48によって開閉可能に構成されている。
図3に示されるように、第4区画壁64に形成された上段側の通気口85,86は、上段側の第2空気流通路60aに連通している。また、下段側の通気口87,88は、下段側の第2空気流通路60bに連通している。
図2に示されるように、第3区画壁63に設けられたダンパ41~44のうち、上段側の前後のダンパ43,44は交互に開閉し(一方が開いたときに他方が閉じ、他方が開いたときに一方が閉じる)、同様に、下段側の前後のダンパ41,42も交互に開閉する。また、前側の上下のダンパ43,41は交互に開閉し、後側の上下のダンパ44,42も交互に開閉する。
同様に、第3,第4区画壁63,64に設けられた上段側のダンパ43,44,45,46のうち、前側に配置された2つのダンパ43,45が組となって同時に開閉し、後側に配置された2つのダンパ44,46が組となって同時に開閉する。
図5に示される態様では、第1ファン34によって内気取入口53から取り入れられた室内空気が、第1熱交換室57を通過して第1中継吹出口22a及び第1中継取入口22bを介して第1ケーシング11A内に流入し、排気吹出口52から排出される。また、第2ファン35によって外気取入口51から取り入れられた室外空気が、第2熱交換室58を通過して第2中継吹出口23a及び第2中継取入口23bを介して第1ケーシング11A内に流入し、給気吹出口54から排出される。
図7(a)に示されるように、内気取入口53から下段側の第2空気流通路60bを流れる空気流は、第4区画壁64の下段前側に形成された通気口87を介して第1熱交換室57に流入する。その後、当該空気流は、第1熱交換器31を通過し、第3区画壁63の下段前側に形成された通気口81を介して下段側の第1空気流通路59bに流入し、第1中継吹出口22aから排出される。
図8(a)に示されるように、内気取入口53から下段側の第2空気流通路60bを流れる空気流は、第4区画壁64の下段後側に形成された通気口88を介して第2熱交換室58に流入する。その後、当該空気流は、第2熱交換器32を通過し、第3区画壁63の下段後側に形成された通気口82を介して下段側の第1空気流通路59bに流入し、第1中継吹出口22aから室内に排出される。
まず、除湿運転について説明する。第1の冷凍サイクル動作は、図4(a)に示されるように、圧縮機27から吐出された冷媒が、第1熱交換器31で放熱して凝縮し、その後に電動膨張弁28へ送られて減圧される。減圧された冷媒は、第2熱交換器32で吸熱して蒸発し、その後に圧縮機27に吸入されて圧縮され、再び吐出される。したがって、第1の冷凍サイクル動作では、第1熱交換器31が凝縮器として機能し、第2熱交換器32が蒸発器として機能する。
次に、加湿運転について説明する。図4(a)に示される第1冷凍サイクル動作では、第1熱交換器31が凝縮器として機能し、第2熱交換器32が蒸発器として機能する。このとき、図6及び図8に示されるように、外気取入口51から取り入れられた室外空気OAは第1熱交換器31を通過し、熱交換後の空気SAが給気吹出口54から排出される。内気取入口53から取り入れられた室内空気RAは第2熱交換器32を通過し、熱交換後の空気EAが排気吹出口52から排出される。具体的に、凝縮器としての第1熱交換器31においては、吸着剤に吸着されていた水分が冷媒の熱によって脱離し、室外空気OAに取り込まれる。これにより、吸着剤が再生されるとともに室外空気OAが加湿され、加湿後の空気SAが給気吹出口54から室内に供給される。また、蒸発器としての第2熱交換器32においては、冷媒の吸熱によって室内空気RAに含まれる水分が吸着剤に吸着(回収)され、室内空気RAが除湿される。除湿後の空気EAは、排気吹出口52から室外へ排出される。
次に、図10~図17を参照して本発明の第2の実施の形態を説明する。本実施の形態は、主に空気流制御機構13の構成が上記第1の実施の形態と異なっている。
本実施の形態の空気流制御機構13は、図10~図12に示されるように、第1ケーシング11A内に室外空気及び室内空気を取り込み、これらを第2ケーシング11Bへ送ってそれぞれ熱交換器31,32を通過させた後に第2ケーシング11Bから室内及び室外に吹き出す空気流を生成するように構成されている。具体的に、空気流制御機構13における第1ファン34及び第2ファン35は、第1ケーシング11A内に室外空気及び室内空気を吸い込む。
図10に示されるように、第1ケーシング11Aの内部には、第1の実施の形態と同様に、第1ファン34及び第2ファン35が配置される第1,第2送風室56a,56bが第2区画壁62により区画されて設けられている。
図10及び図17に示されるように、第4側板21dの左右両端部の前側には、左右方向の外側ほど前方に位置するように傾斜する傾斜板21d1が設けられている。そして、この傾斜板21d1に第1,第2ファン34,35の吐出口38bが接続されている。また、第1,第2ファン34,35は、各羽根車37の回転軸が、傾斜板21d1と略平行となるように配置されている。したがって、第1,第2ファン34,35は、第2側板21b及び第3側板21cに対して傾斜した姿勢で配置されている。
したがって、本実施の形態では、比較的メンテナンス頻度の高い電装品ユニット15、第1,第2ファン34,35、及び冷媒回路12の一部(四路切換弁26等)とともに、エアフィルタ71も第1ケーシング11Aに集中して配置され、これらのメンテナンスのための作業スペースを第1ケーシング11Aの一側(第1側板21aの前方)に集中して形成することができる。
図11に示されるように、第1空気流通路59は、第6区画壁66によって上下2段に区画されている。第6側板24b(図10参照)に形成された第1中継取入口22bは、下段側の第1空気流通路59bに連通している。また、排気吹出口52は、上段側の第1空気流通路59aに連通している。
図12に示されるように、第2空気流通路60は、第7区画壁67によって上下2段に区画されている。第7側板24c(図10参照)に形成された第2中継取入口23bは、上段側の第2空気流通路60aに連通している。また、給気吹出口54は、下段側の第2空気流通路60bに連通している。
なお、本実施の形態においても、第2ケーシング11Bに形成された通気口81~88や、これを開閉するダンパ41~44の構成は第1の実施の形態と同様である。
また、各ダンパ41~48の開閉パターンも第1の実施の形態と同様である。そして、本実施の形態では、上記ダンパ41~48の開閉パターンの組み合わせによって、図13に示される態様と、図14に示される態様とに空気流が切り換えられる。
図13に示される態様では、第1ケーシング11A内の第1ファン34によって外気取入口51から取り入れられた室外空気が、第1中継吹出口22a及び第1中継取入口22bを介して第2ケーシング11B内に流入し、第1熱交換室57を通過して給気吹出口54から排出される。また、第1ケーシング11A内の第2ファン35によって内気取入口53から取り入れられた室内空気が、第2中継吹出口23a及び第2中継取入口23bを介して第2ケーシング11B内に流入し、第2熱交換室58を通過して排気吹出口52から排出される。
図15(a)に示されるように、第1中継取入口22bから下段側の第1空気流通路59bを流れる空気流は、第3区画壁63の下段前側に形成された通気口81を介して第1熱交換室57に流入する。その後、当該空気流は、第1熱交換器31を通過し、第4区画壁64の下段前側に形成された通気口87を介して下段側の第2空気流通路60bに流入し、給気吹出口54から室内に排出される。
図16(a)に示されるように、第1中継取入口22bから下段側の第1空気流通路59bを流れる空気流は、第3区画壁63の下段後側に形成された通気口82を介して第2熱交換室58に流入する。その後、当該空気流は、第2熱交換器32を通過し、第4区画壁64の下段後側に形成された通気口88を介して下段側の第2空気流通路60bに流入し、給気吹出口54から室内に排出される。
本実施の形態における除湿運転について説明する。図4(a)に示される第1の冷凍サイクル動作では、圧縮機27から吐出された冷媒が、第1熱交換器31で放熱して凝縮し、その後に電動膨張弁28へ送られて減圧される。減圧された冷媒は、第2熱交換器32で吸熱して蒸発し、その後に圧縮機27に吸入されて圧縮され、再び吐出される。したがって、第1の冷凍サイクル動作では、第1熱交換器31が凝縮器として機能し、第2熱交換器32が蒸発器として機能する。
次に、加湿運転について説明する。図4(a)に示される第1冷凍サイクル動作では、第1熱交換器31が凝縮器として機能し、第2熱交換器32が蒸発器として機能する。このとき、図13及び図15に示されるように、外気取入口51から取り入れられた室外空気OAは第1熱交換器31を通過し、熱交換後の空気SAが給気吹出口54から排出される。内気取入口53から取り入れられた室内空気RAは第2熱交換器32を通過し、熱交換後の空気EAが排気吹出口52から排出される。具体的に、凝縮器としての第1熱交換器31においては、吸着剤に吸着されていた水分が冷媒の熱によって脱離し、室外空気OAに取り込まれる。これにより、吸着剤が再生されるとともに室外空気OAが加湿され、加湿後の空気SAが給気吹出口54から室内に供給される。また、蒸発器としての第2熱交換器32においては、冷媒の吸熱によって室内空気RAに含まれる水分が吸着剤に吸着(回収)され、室内空気RAが除湿される。除湿後の空気EAは、排気吹出口52から室外へ排出される。
例えば、第1の実施の形態では、図1に示されるように、外気取入口51及び内気取入口53が、それぞれ第6側板24b及び第7側板24cに形成されているが、いずれも第8側板24dに形成することができる。また、第2の実施の形態では、図10に示されるように、排気吹出口52及び給気吹出口54は、それぞれ第6側板24b及び第7側板24cに形成されているが、いずれも第8側板24dに形成することができる。
また、第2の実施の形態において、第1,第2ファン34,35は、吸込口38aが設けられた側面が第2側板21b及び第3側板21cと平行になるように配置されていてもよい。この場合においても、第1,第2ファン34,35と第1ケーシング11Aの第2,第3側板21b,21cとの間には空気引込空間70が形成されていることが好ましい。
