Abstract

　第１容器１と第２容器２とを接続する蒸気ダクト１６中に，正逆回転可能にした蒸気圧縮機１７を設け，この蒸気圧縮機１７を第１容器から第２容器の方向に蒸気圧縮を行うように正方向に回転して冷房運転にし，前記蒸気圧縮機を第２容器から第１容器の方向に蒸気圧縮を行うように逆方向に回転して暖房運転にする蒸発式空調装置において，そのランニングコストの低減を図るとともに，冷房運転の際における大気の上昇に伴う冷暖房箇所の温度上昇を防止する。前記蒸気ダクト１６に前記蒸気圧縮機１７に対するバイパス蒸気通路１９を設けて，このバイパス蒸気通路に通常閉の蒸気バイパス弁２０を設け，前記冷房運転中において，前記第２容器２側の温度が前記第１容器１側の温度よりも低くなったとき，前記蒸気圧縮機の回転を停止する一方，前記蒸気バイパス弁２０を開く構成にする。
