Zusammenfassung:	The utility model aims to provide an improved falling film evaporator used in a refrigeration air-conditioning system, which further enhance the heat transfer efficiency by enhancing the oil return efficiency. The improved falling film evaporator used in the refrigeration air-conditioning system comprises a shell, horizontal tube bundles arranged in the shell, a liquid collecting disc arranged between the tube bundles in the upper part of the shell and the tube bundles in the lower part of the shell, a refrigerant distributor arranged at the top of the shell, a tube support plate arranged in the shell for supporting the liquid collecting disc, and an oil return joint at the bottom of the shell. The improved falling film evaporator used in the refrigeration air-conditioning system is characterized in that the liquid collecting disc is partially inclined in a length direction.
