摘要:
In some embodiments, a refrigeration device includes: walls substantially forming a liquid-impermeable container configured to hold phase change material internal to a refrigeration device; at least one active refrigeration unit including a set of evaporator coils positioned within an interior of the liquid-impermeable container; walls substantially forming a storage region; and a heat transfer system including a first group of vapor-impermeable structures with a hollow interior connected to form a condenser in thermal contact with the walls substantially forming a liquid-impermeable container, a second group of vapor-impermeable structures with a hollow interior connected to form an evaporator in thermal contact with the walls substantially forming a storage region, and a connector with a hollow interior affixed to both the condenser and the evaporator, the connector forming a liquid and vapor flow path between the hollow interior of the condenser and the hollow interior of the evaporator.
