1. A refrigeration evaporator for use in refrigeration systems, the refrigeration evaporator comprising:
a plurality of fluidly connected liquid chambers disposed between first and second layers of material,
an inlet for receiving and introducing liquid refrigerant into at least one of said plurality of liquid chambers; and wherein each of the liquid chambers are interconnected by respective overflow inlets and outlets to allow flow of liquid refrigerant between the plurality of fluidly connected liquid chambers under gravity such during influent flow of the refrigerant liquid through the inlet, the liquid chambers accumulate the refrigerant liquid sequentially to impede the flow of the refrigerant liquid;
a vapor circuit comprising respective draw off vapor channels being provided to receive flow of refrigerant vapor from corresponding liquid chambers, the draw off vapor channels being in fluid communication with peripheral vapor channels disposed along peripheral regions of the refrigeration evaporator for reducing or preventing slugs of liquid refrigerant flowing into the vapor circuit
wherein the vapor circuit and the overflow inlets and outlets are disposed between the first and second layers of material; and
wherein the overflow inlets for each liquid chamber is fluidly connected with respective overflow channels disposed along peripheral regions of corresponding liquid chambers and wherein the vapor channels are disposed radially outwardly relative to the overflow channels.
