Thermoelectric refrigeration

FOOD PRESERVATION - REFRIGERATION AND FREEZING

 

Thermoelectric refrigeration provides a very simple and reliable solution for cooling, as no fluids are required. The maximum cooling temperature is usually restricted to 30°C below the external air temperature, and the cooling efficiency is typically lower than in vapour compressors.

 

 

Advantages/Disadvantages

Advantages

  • Lightweight, portable system;
  • On site assembly;
  • Low maintenance;
  • Compactness and durability;
  • No flammable or toxic refrigerant used;
  • Low or no effect on a food's taste or texture;
  • Possibility to be directly powered by PV system;
  • Lower cost than vapour compressor;
  • Exploitable for heating and cooling.

Disadvantages

  • Lower efficiency than other refrigeration systems;
  • Energy consumption;
  • Electrical energy is needed;
  • Maximum cooling temperature is limited to 30°C below the external air temperature;
  • Applicable only to small systems.
