  • the object of the invention is a method and system for storing heat or cold in vehicles with electric propulsion.
  • Cold accumulators using fluids freezing in low temperatures are widely used in refrigeration technology to compensate for extreme heat loads and save the consumption of electric energy by a refrigerating device described by the authors Recknagel H. Sprenger E. Honmann W. Schramek E.R. Ogrzewanie i palatyzacja, Poradnik, Gdarisk, 1994, p. 1814.

  • the low working efficiency of the accumulators both in the charging and the discharging mode is associated with the necessity to overcome heat resistances created by a thick ice layer, since freezing the layer takes place at one side of the accumulator, while ice melting - at the other side.
  • the accumulation of cold on the cold side of the unit is usually not used.
  • Thermoelectric refrigeration units with an ice-water type accumulator described in patent document PL 209274 B1 .
  • Technical solutions of this type are proposed by a heat exchanger in the form of a finned plate on the hot side and radiators with fans on the cold side.
  • the cold accumulator has been realised as a finned plate with hollowed fins. Hermetically sealed internal spaces of the fins are filled with water. From the side of the base, the accumulator is thermally insulated by a layer of insulation. The spatial shape of the accumulator fins reflects the shape of radiator channels.
  • the accumulator may be set on two working positions: t - charging, and R - discharging. Cooling the interior of the chamber may take place by the means of: only the unit itself, by the means of only the inserts or jointly by the unit and the inserts. Before use, the cold storage unit must be frozen during stoppage, while night rate is in effect. An additional disadvantage is the problem of freezing the radiators, which sometimes makes it impossible to switch from the charging mode to the discharge of the storage tank.
  • thermoelectric module of the low temperature stage installed on the wall of the accumulator container, filled with water.
  • Water is refrigerated by the means of the evaporator of the refrigerating device - high temperature stage placed inside the container. Ice is created on the evaporator and fills the space between the evaporator and the wall on which the thermoelectric module is located. The freezing of ice proceeds from the bottom, and its melting - from the top, as a result of which the ice layer is always placed in the way of the heat stream between the low and high temperature stages.
  • Another drawback of this solution is the heating of water in the near-wall layer above 0 °C with an increased heat load. Equalising the temperature of water and melting ice is possible only when using a stirrer. However, such a solution results in complexity of construction, an increase in the volume and mass of the accumulator, which is unacceptable in the case of mobile systems.

It comprises a thermally insulated refrigeration chamber, a thermoelectric unit placed in its cover, powered from the electrical network of the vehicle and the so-called inserts, i.e. cold storage tanks having the form of flat containers, filled with fluid freezing at a low temperature, inserted into the chamber. Cooling the interior of the chamber may take place by the means of the unit only, by the means of the inserts only or jointly. The inserts must be frozen before use in a home freezer or by the means of another freezing device.
