本明細書において用語「冷媒」には、ISO817(国際標準化機構)で定められた、冷媒の種類を表すRで始まる冷媒番号(ASHRAE番号)が付された化合物が少なくとも含まれ、さらに冷媒番号が未だ付されていないとしても、それらと同等の冷媒としての特性を有するものが含まれる。冷媒は、化合物の構造の面で、「フルオロカーボン系化合物」と「非フルオロカーボン系化合物」とに大別される。「フルオロカーボン系化合物」には、クロロフルオロカーボン(CFC)、ハイドロクロロフルオロカーボン(HCFC)及びハイドロフルオロカーボン(HFC)が含まれる。「非フルオロカーボン系化合物」としては、プロパン(R290)、プロピレン(R1270)、ブタン(R600)、イソブタン(R600a)、二酸化炭素(R744)及びアンモニア(R717)等が挙げられる。
(2-1)冷媒成分
詳細は後述するが、冷媒A、冷媒B、冷媒C、冷媒D、冷媒Eの各種冷媒のいずれか1種を冷媒として用いることができる。
本開示の冷媒は、冷凍機における作動流体として好ましく使用することができる。
本開示の冷媒組成物は、本開示の冷媒を少なくとも含み、本開示の冷媒と同じ用途のために使用することができる。また、本開示の冷媒組成物は、さらに少なくとも冷凍機油と混合することにより冷凍機用作動流体を得るために用いることができる。
本開示の冷媒組成物は微量の水を含んでもよい。冷媒組成物における含水割合は、冷媒全体に対して、0.1質量%以下とすることが好ましい。冷媒組成物が微量の水分を含むことにより、冷媒中に含まれ得る不飽和のフルオロカーボン系化合物の分子内二重結合が安定化され、また、不飽和のフルオロカーボン系化合物の酸化も起こりにくくなるため、冷媒組成物の安定性が向上する。
トレーサーは、本開示の冷媒組成物が希釈、汚染、その他何らかの変更があった場合、その変更を追跡できるように検出可能な濃度で本開示の冷媒組成物に添加される。

図16は、第1実施形態に係る空気調和装置1の配置を示す模式図である。図17は、空気調和装置1の概略構成図である。図16及び図17において、空気調和装置1は、住宅やビルの空調に使用される装置である。
空調機器80のヒートポンプ部360では、冷媒回路320は、室内機2と、室外機3とが冷媒連絡管306、307を介して接続されることによって構成されている。冷媒連絡管306、307は、空調機器80を設置する際に、現地にて施工される冷媒管である。
ヒートポンプ暖房運転が行われているとき、空気調和装置1では、少なくとも1,2-ジフルオロエチレンを含む冷媒が、圧縮機321と利用側熱交換器である室内熱交換器242と熱源側熱交換器である室外熱交換器323とを循環して冷凍サイクルを繰り返す。室内熱交換器242が、第1空気である室内空気F1と冷媒とに熱交換させる。室内空気F1が、室内ファン240によって室内熱交換器242に供給される。室内熱交換器242において加熱された室内空気F3(第1空気)は、第1ダクト209を通じて室内機2から各部屋101~104に送られて、暖房が行われる。室外熱交換器323が、第2空気である室外空気と冷媒に熱交換させる。ケーシング230は、第1ダクト209に接続され且つ室内熱交換器242を収納している利用側空間SP2を有し、室内熱交換器242で冷媒と熱交換された後の室内空気F3を第1ダクト209に送出するように構成されている。
別熱源部270は、空調機器80の室内機2の一部であるガスファーネスユニット205によって構成されている。
室内ファン240は、ヒートポンプ部360を構成する冷媒放熱器としての室内熱交換器242や別熱源部270を構成する別熱源放熱器としてのファーネス熱交換器255によって加熱される空気を部屋101~104内に供給するための送風機である。
室内機2は、室内機2の各部の動作を制御する室内側制御基板21を搭載している。室外機3は、室外機3の各部の動作を制御する室外側制御基板31を搭載している。そして、室内側制御基板21及び室外側制御基板31はマイコン等を有しており、サーモスタット40との間で制御信号等のやりとりを行う。また、室内側制御基板21と室外側制御基板31との間では制御信号のやりとりは行わない。室内側制御基板21及び室外側制御基板31を含めた制御装置をコントローラ30という。
図18は本発明の第1実施形態に係る空気調和装置1におけるコントローラ30及びサーモスタット40の電気的接続状態を示すブロック図である。サーモスタット40は、室内機2と同じように屋内空間に取り付けられる。なお、サーモスタット40および室内機2それぞれが取り付けられる場所は、屋内空間の異なる場所でもよい。また、サーモスタット40は、室内機2及び室外機3それぞれの制御系と通信線で繋がっている。
(7-1)全体構成
第2実施形態に係る空気調和装置701は、図19に示されているように、建物800の屋根801の上、すなわち屋上に設置される。空気調和装置701は、建物800の内部である屋内の空気調和を行なう機器である。建物800は、複数の部屋810を有している。建物800の部屋810が、空気調和装置701にとっての空調対象空間になる。図19には、空気調和装置701が、1つの第1ダクト721及び1つの第2ダクト722を備えている例が示されている。しかし、空気調和装置701は、これら第1ダクト721及び第2ダクト722を、それぞれ複数備えるように構成することもできる。なお、図19に示されている第1ダクト721は、途中で枝分かれしている。第1ダクト721は、サプライエアのために設けられており、第2ダクト722は、リターンエアのために設けられている。第1ダクト721で室内の複数の部屋810に供給されるサプライエアが第1空気である。第2ダクト722で室内から取り入れられるリターンエアも第1空気である。図19において、第1ダクト721、第2ダクト722の中の矢印Ar1,Ar2は、第1ダクト721、第2ダクト722の中の空気が流れている方向を示している。空気調和装置701から部屋810には第1ダクト721を通って空気が送られ、空調対象空間の空気である部屋810の屋内空気が第2ダクト722を通って空気調和装置701に送られる。第1ダクト721と部屋810との境界には、複数の吹出口723が設けられている。第1ダクト721で供給されるサプライエアは、吹出口723から部屋810に吹出される。また、第2ダクト722と部屋810の境界には、少なくとも一つの吸込口724が設けられている。吸込口724から吸い込まれた屋内空気は、第2ダクト722によって空気調和装置701に戻されるリターンエアとなる。
図20には、空気調和装置701を斜め上方から見た空気調和装置701の外観が示され、図21には、空気調和装置701を斜め下方から見た空気調和装置701の外観が示されている。以下においては、便宜的に、図に矢印で示されている上下前後左右の方向を用いて説明する。空気調和装置701は、直方体を基礎とする形状を有するケーシング730を備えている。このケーシング730が、上面730a、正面730b、右側面730c、左側面730d、背面730e及び底面730fを覆う金属板を含んでいる。ケーシング730は、上面730aに第3開口733を有している。この第3開口733が熱源側空間SP1(図22参照)に連通している。第3開口733を通して熱源側空間SP1の空気をケーシング730の外に吹出させる熱源側ファン747が、第3開口733に取り付けられている。熱源側ファン747には、例えばプロペラファンが用いられる。また、ケーシング730が、正面730b、左側面730d及び背面730eにスリット734を有している。これらスリット734も、熱源側空間SP1に連通している。熱源側ファン747によって熱源側空間SP1からケーシング730の外側に向って空気が吹出されると、熱源側空間SP1が大気圧に対して負圧になるので、スリット734を通してケーシング730の外部から熱源側空間SP1に屋外空気が吸い込まれる。なお、第3開口733及びスリット734は、利用側空間SP2(図22参照)には連通していない。従って、通常の状態では、第1ダクト721、第2ダクト722以外に、利用側空間SP2からケーシング730の外部に連通する箇所はない。
(7-3-1)ケーシング730の中の熱源側空間SP1と利用側空間SP2
図22には、ケーシング730の正面730bを覆っていた金属板及び左側面730dを覆っていた金属板が取り外された状態が示されている。図23には、ケーシング730の右側面730cを覆っていた金属板及び背面730eを覆っていた一部の金属板が取り外された状態が示されている。図23において、背面730eを覆っていた金属板のうちの取り外された金属板は、利用側空間SP2を覆っていた金属板である。従って、図23に示されている、背面730eを覆っている金属板は、熱源側空間SP1のみを覆っている。そして、図24には、ケーシング730の右側面730cを覆っていた金属板、左側面730dを覆っていた金属板、背面730eを覆っていた金属板及び上面730aの一部を覆っていた金属板が取り外され且つ熱源側熱交換器743及び熱源側ファン747が取り外された状態が示されている。
熱源側空間SP1には、熱源側ファン747以外にも、圧縮機741、四方弁742、熱源側熱交換器743及びアキュムレータ746が収納されている。熱源側熱交換器743は、冷媒が中を流れる複数の伝熱管(図示せず)と、互いの隙間を空気が流れる複数の伝熱フィン(図示せず)とを含んでいる。複数の伝熱管が上下方向(以下、行方向ともいう)に並んでいて、各伝熱管が上下方向と実質的に直交する方向(実質的に水平方向)に延びている。また、複数の伝熱管は、ケーシング730に近い側から順に複数列設けられている。熱源側熱交換器743の端部では、ある列から他の列に及び/またはある行から他の行に冷媒の流れが折り返されるように、例えばU字状に曲げられ或いはU字管で伝熱管同士が接続されている。上下方向に長く延びた複数の伝熱フィンは、互いに所定の間隔を保って、伝熱管の延びる方向に沿って並べられている。各伝熱フィンを複数の伝熱管が貫通するように、複数の伝熱フィンと複数の伝熱管とが組み合わされている。そして、複数の伝熱フィンも複数列に配置されている。
利用側空間SP2には、膨張弁744、利用側熱交換器745及び利用側ファン748が配置されている。利用側ファン748には、例えば遠心ファンが用いられる。遠心ファンとしては、例えばシロッコファンがある。なお、膨張弁744は、熱源側空間SP1に配置されてもよい。図23に示されているように、利用側ファン748は、支持台751によって、第1開口731の上方に配置されている。利用側ファン748の吹出口748bは、図29に示されているように、上面視において、第1開口731とは重ならない位置に配置されている。支持台751とケーシング730によって利用側ファン748の吹出口748bと第1開口731以外の部分が囲まれているので、利用側ファン748の吹出口748bから吹出される空気は、実質的に全て第1開口731から第1ダクト721を通して屋内に供給される。
図26には、空気調和装置701の中に構成されている冷媒回路711が示されている。冷媒回路711は、利用側熱交換器745と熱源側熱交換器743とを含んでいる。この冷媒回路711において、利用側熱交換器745と熱源側熱交換器743の間を冷媒が循環する。この冷媒回路711では、冷房運転または暖房運転において蒸気圧縮式の冷凍サイクルが実施されているときに、利用側熱交換器745と熱源側熱交換器743で熱交換が行なわれる。図26において、矢印Ar3は、利用側熱交換器745の下流側の気流であって利用側ファン748から吹出されるサプライエアを示しており、矢印Ar4は、利用側熱交換器745の上流側の気流であるリターンエアを示している。また、矢印Ar5は、熱源側熱交換器743の下流側の気流であって熱源側ファン747によって第3開口733から吹出される気流を示しており、矢印Ar6は、熱源側熱交換器743の上流側の気流であって熱源側ファン747によってスリット734から吸い込まれる気流を示している。
図27には、空気調和装置701を制御するメインコントローラ760とそのメインコントローラ760によって制御される主な機器などが示されている。メインコントローラ760は、圧縮機741、四方弁742、熱源側ファン747及び利用側ファン748を制御する。メインコントローラ760は、リモートコントローラ762と通信できるように構成されている。ユーザは、部屋810の室内温度の設定値などをリモートコントローラ762からメインコントローラ760に送信することができる。
図30には、第3実施形態に係る空気調和装置601の構成が示されている。この空気調和装置601は室内の換気と調湿とを行うように構成されたものである。空気調和装置601のケーシング621の中の中央部には、顕熱交換器622が設けられている。顕熱交換器622とは、流通空気間で湿分の交換は行わず、顕熱の熱交換だけを行う機能を有するものである。
上述の第1実施形態、第2実施形態及び第3実施形態の空気調和装置(1,601,701)は、圧縮機(321,633,741)と、室内熱交換器242、給気熱交換器625または利用側熱交換器745と、室外熱交換器323,634または熱源側熱交換器743と、冷媒A~Eのいずれかと、第1ダクト209,721または給気ダクト651と、ケーシング230,621,730とを備えている。
