THERMOELECTRIC REFRIGERATING DEVICE WITH COLD ACCUMULATOR Russian patent published in 2017 - IPC F25D3/00 

FIELD: heating.

SUBSTANCE: refrigerating device includes thermoelectric module, the cold side of which is thermally coupled with user of refrigeration, at least two closed hydraulic loops, providing refrigerating of the thermoelectric module hot side, one of which has a radiator for heat release into the environment, while the second provides the heat removing to the cold accumulator, which is designed as the thermally insulated container, filled with a working medium, which has a phase transition temperature higher than the nominal ambient temperature, but below the temperature at which the stable operation is provided by the thermoelectric module.

EFFECT: provision of the specified refrigerating capacity and power efficiency of the thermoelectric refrigerating system operation and maintaining of the required temperature of the user, with the possible periodic ambient temperature increase above the designed.
