PROBLEM TO BE SOLVED: To provide a freezer for ship including a water cooling type condenser, which even when a hole is made on a cooling pipe, prevents damage of components of a refrigerant circuit.SOLUTION: An air conditioner 10 is installed in a ship, and includes a refrigerant circuit 20 in which a compression mechanism 30, a water cooling type condenser 40, an expansion mechanism 50 and an evaporator 60 are sequentially connected, wherein provided are: an abnormal determination unit 81 configured to determine whether the condenser 40 is in an abnormal state where refrigerant of a refrigerant chamber S1 leaks into a cooling pipe 42; and an abnormality-time operation unit 82 configured to perform predetermined abnormality-time operation to prevent cooling water from entering from the cooling pipe 42 to the refrigerant circuit 20, in a case where the abnormality determination unit 81 determines that it is in the abnormal state.SELECTED DRAWING: Figure 1

    【課題】水冷式の凝縮器を備えた舶用の冷凍装置において、冷却管に穴があいた場合であっても冷媒回路の構成部品の破損を防止する。【解決手段】船舶に搭載され、圧縮機構(30)と水冷式の凝縮器(40)と膨脹機構(50)と蒸発器(60)とが順次接続された冷媒回路(20)を備えた空気調和装置(10)に、凝縮器(40)において、冷媒室(S1)の冷媒が冷却管(42)内へ漏れている異常状態であるか否かを判定する異常判定部(81)と、該異常判定部(81)が異常状態と判定すると、冷却管(42)から冷媒回路(20)への冷却水の浸入を回避するための所定の異常時動作を行う異常時動作部(82)とを設ける。【選択図】図1
