Patent ID: 8726688

Claim:
A refrigerator for fresh products with passive means for temperature levelling without using ventilation, comprising a body which forms internally at least one compartment which is delimited by thermally insulating walls, wherein at least 50% of an inner surface of said compartment is constituted by a surface of a heat accumulator which contains a eutectic liquid, with a phase change temperature which is proximate to a temperature to be maintained within said compartment, an evaporation circuit associated with a compressor being functionally connected to said heat accumulator, and wherein a ration between the surface in square meters of said compartment and the volume in cubic meters of said compartment is provided greater than 3.5, said evaporation circuit being arranged so that, in operation, a ΔT<8° C. is maintained between refrigeration fluid that circulates therein and the temperature inside said compartment.
