Therman Transfer Device and Storage Systems Including Same

A refrigeration evaporator for use in refrigeration systems, the evaporator comprising:

• a plurality of fluidly connected liquid chambers;
• an inlet for receiving and introducing liquid refrigerant into one of said plurality of liquid chambers;
• and wherein each of the liquid chambers are interconnected by overflow channels to allow flow of liquid refrigerant between the plurality of fluidly connected liquid chambers under gravity such during influent flow of the refrigerant liquid the liquid chambers accumulate the refrigerant liquid sequentially to impede the flow of the refrigerant liquid;
• a vapour circuit being provided to receive flow of refrigerant vapour from corresponding liquid chambers, the vapour circuit comprising vapour flow paths disposed within the overflow channels
• wherein each overflow channel comprises a sufficiently large cross-section to facilitate flow of vapour along the vapour flow paths therein to allow the liquid to collect and flow without the vapour pushing slugs of the liquid through the cross-section without blocking the flow of the vapour.
