摘要： The present application discloses a falling film evaporator including a barrel that is provided with an upper distributor at an inner upper side thereof, gas barriers are respectively provided at both sides of the top of the upper distributor, at least one gas barrier is provided with sawteeth at the edge thereof, a gas flowing channel is formed by the sawteeth and the inner wall of the barrel in an encircled manner and is communicated with the gas refrigerant outlet, at the bottom of the both side walls of the upper distributor is respectively provided with a turbulent flow plate, an upper heat exchange tube group is provided below the upper distributor, a lower heat exchange tube group is provided below the upper heat exchange tube group, an oil enriched area provided with a liquid level sensor is provided below the lower heat exchange tube group, a signal output end of the liquid level sensor is connected with a signal input end of the throttle device, and oil return ports are opened at the oil enriched area. The falling film evaporator may switch between full falling film heat exchange mode and mixed falling film heat exchange mode, thereby preventing refrigerant dripping to the bottom for use in heat exchange from being insufficient or preventing refrigerant filling quantity from being too large, and meanwhile also avoiding the phenomenon of carrying liquid during air suction and improving heat transfer coefficient and heat exchange efficiency.
摘要翻译：本申请公开了一种降膜蒸发器，其包括在其内部上侧设置有上部分配器的筒体，在上部分配器的顶部的两侧分别设置有气体阻挡件，至少一个气体屏障设置有锯齿在其边缘处，气体流动通道由圆筒状的锯条和筒的内壁以包围的方式形成并与气体制冷剂出口连通，在上部分配器的两个侧壁的底部分别设有湍流板，上部分配器下方设置有上部热交换管组，在上部热交换管组的下方设置有下部热交换管组，在下部热量的下侧设置有设置有液位传感器的富油区域交换管组，液位传感器的信号输出端与节流装置的信号输入端连接，回油口为opene d在富油区域。降膜蒸发器可以在全降膜热交换模式和混合降膜热交换模式之间切换，从而防止制冷剂滴入底部以用于热交换不足或防止制冷剂填充量过大，同时还避免吸气期间携带液体的现象，提高传热系数和热交换效率。
