Abstract
A refrigeration evaporator comprising fluidly connected liquid chambers disposed between first and second layers of material, and an inlet for receiving and introducing liquid refrigerant into one of the liquid chambers. Each of the chambers are interconnected by respective overflow inlets and outlets to allow flow of liquid refrigerant between the connected chambers under gravity such that, during influent flow of the liquid through the inlet, the chambers accumulate the liquid sequentially to impede the flow. The evaporator further comprises vapor circuit including respective draw off vapor channels for receiving flow of refrigerant vapor from corresponding chambers. The vapor channels are in fluid communication with peripheral vapor channels disposed along peripheral regions of the evaporator for reducing or preventing slugs of liquid refrigerant flowing into the circuit. The circuit and the overflow inlets and outlets are disposed between the first and second layers of material.
