Description
Claims (4)
- 一対の蒸発器、凝縮器、膨張手段及び圧縮機を接続してなる冷媒回路と、凝縮器内の冷媒と外気とを熱交換させる凝縮器用送風機とを備え、圧縮機から吐出した冷媒を凝縮器及び膨張手段を介して各蒸発器に流通させることにより各蒸発器によってショーケース本体内を冷却する冷却運転と、圧縮機から吐出した冷媒を凝縮器を介して何れか一方の蒸発器に流通させることにより一方の蒸発器を除霜し、一方の蒸発器から吐出した冷媒を膨張手段を介して他方の蒸発器に流通させることにより他方の蒸発器によってショーケース本体内を冷却する除霜運転とを切換可能なショーケースにおいて、
前記圧縮機から吐出する冷媒の圧力を検出する圧力検出手段と、
除霜運転を行う際に、圧力検出手段によって検出された検出圧力が所定の圧力よりも小さいときは凝縮器用送風機を停止し、検出圧力が所定の圧力以上になると凝縮器用送風機を運転する制御手段とを備えた
ことを特徴とするショーケース。 - 前記除霜運転の終了後に圧縮機から冷媒を吐出しながら凝縮器用送風機の運転を所定時間だけ停止する制御手段を備えた
ことを特徴とする請求項1記載のショーケース。 - 前記各蒸発器ごとにそれぞれ設けられた風量調整可能な一対の蒸発器用送風機と、
前記除霜運転において除霜が行われている一方の蒸発器の蒸発器用送風機の運転を停止し、他方の蒸発器の蒸発器用送風機の風量を増加させる制御手段とを備えた
ことを特徴とする請求項1記載のショーケース。 - 前記各蒸発器にそれぞれ設けられた通風路内の空気の流通方向を蒸発器用送風機の送風方向のみに規制する流通規制手段を備えた
ことを特徴とする請求項3記載のショーケース。
