Abstract

A flooded evaporator where floating mist above the surface of refrigerant liquid is highly precisely removed to prevent wet vapor suction where the mist flows to the back flow side of the flooded evaporator to return to the compressor side, and where cooling effect of a medium to be cooled is enhanced by enhancing heat transfer efficiency between the medium to be cooled and refrigerant liquid. These are achieved without an increase in the size of the device. An inner tube (12) for upwardly guiding refrigerant vapor, produced from the refrigerant liquid, is provided inside a tubular housing (3) raised at the upper part of a container (1) that forms a heat exchanging section (2). A cover body (13) having a downward opening for first downwardly deflecting the flow of the refrigerant vapor s that arrives at an upper end opening (15) of the inner tube is disposed so as to face the opening (15) with a gap between them. A space section (17) for causing the refrigerant liquid mixed with the refrigerant vapor to settle by gravity is provided above the cover body (13), and a demister (16) is provided above the space section (17). The area of the gap between the inner tube (12) and the cover body (13) is set smaller than the area of the gap between the inner surface of the tubular housing and the cover body (13), thus a circulation path (20) for the refrigerant liquid is formed in the container (1).
