Abstract (en)
[origin: EP3165851A1] Provided is a falling film evaporator which is able to reduce an outflow of liquid refrigerant even in the case in which a vapor outlet pipe is provided in a location other than the upper middle portion of the tank. A falling film evaporator (1) allows liquid refrigerant of refrigerant in a gas-liquid two-phase state supplied in a tank (10) to downwardly fall onto a heat transfer tube group (20) via a second stage refrigerant tray (35), and is provided with an isolation member (50) covering a place below a lowest portion of a connection portion of the tank (10) and a vapor outlet pipe (18), extending between the vapor outlet pipe (18) and a liquid refrigerant distribution apparatus (30), and allowing refrigerant to pass through an upper portion. The isolation member (50) is provided such that the longitudinal direction of the isolation member (50) is same as a longitudinal direction of the heat transfer tubes (21).
