Abstract
Description
すなわち、本開示の一態様に係る空調機においては、室外熱交換器に外気を供給する室外ファンが収容された室外ファン室と、電子部品が収められるコントロールボックスが収容された機械室と、が設けられた室外機を備え、前記機械室には、換気風を該機械室の内部へ供給する送風口が、前記コントロールボックスに対して同じ高さ以上に設けられている。
また、送風口はコントロールボックスに対して同じ高さ以上に備えることとした。これによれば、漏れ出した冷媒ガスを、換気風によって巻き上げてしまう現象を抑制できる。冷媒が可燃性である場合、冷媒が巻き上げられると、コントロールボックス内の電子部品に触れてしまい、電子部品がショートした際の引火や爆発の危険性を高めてしまう。しかし、上記構成によって、冷媒を巻き上げてしまう現象を抑制できるので、引火や爆発の危険性を、より低減できる。
図1を参照して、本実施形態に係る空調機10の構成について説明する。
図1に示すように、本実施形態に係る空調機10においては、室外機100と室内機200とが、冷媒が流通する冷媒配管310を介して接続されている。
空調機10を構成する熱交換サイクルには、例えば、R32などの低GWP(地球温暖化係数)冷媒が用いられている。R32などの低GWP冷媒は、可燃性を有している。
コントロールボックス131が収容された機械室130の内部へ換気風を供給する送風口132を備えることとした。これによれば、換気風を送風口132から機械室130の内部へ供給することで、機械室130内に滞留する気体を、換気風によって機械室130の外部へ効率的に排気させることができる。これによって、機械室130内において冷媒ガスが漏れ出した場合、機械室130の下部に滞留する冷媒ガスを、機械室130の外部に排気することが可能になる。特に、冷媒が可燃性である場合、電子部品のショート等によって生じる恐れのある引火や爆発の危険性を低減できる。また、送風口132によって機械室130内の換気が常時可能な状態になるので、冷媒漏れが発生し易い部品(例えば、継手や弁)を機械室130内に設置できる。
また、送風口132はコントロールボックス131に対して同じ高さ以上に備えることとした。これによれば、漏れ出した冷媒ガスを、換気風によって巻き上げてしまう現象を抑制できる。冷媒が可燃性である場合、冷媒が巻き上げられると、コントロールボックス131内の電子部品に触れてしまい、電子部品がショートした際の引火や爆発の危険性を高めてしまう。しかし、上記構成によって、冷媒を巻き上げてしまう現象を抑制できるので、引火や爆発の危険性を、より低減できる。
図2を参照して、本実施形態に係る空調機12の構成について説明する。
本実施形態は、上述した第1実施形態に対して送風口132や換気ファン400等の形態が異なり、その他の点では同様である。したがって、第1実施形態と異なる点についてのみ説明し、その他は同一の符号を用いてその説明を省略する。
送風ダクト320の一端は、機械室130の筐体110の右側面上部に設けられた送風口132に接続されている。また、送風ダクト320の他端は、室内機200内に設けられた換気ファン400に接続されている。換気ファン400を運転することで、室内から空気(換気風)を吸い込み、送風ダクト320を介して機械室130の内部へ送風する。
換気ファン400は室内機200に設けられ、換気ファン400と送風口132とは、送風ダクト320を介して接続されることとした。これによれば、機械室130と換気ファン400とは隔離されているので、換気ファン400を駆動するモータと可燃性の冷媒とが接触することを防止して、引火や爆発の危険性を低減できる。
