Thermoelectric cooling-heating unit for thermostatic body of pickup refrigerated trucks

An applicability of thermoelectric method for thermostatic control in pickup refrigerated trucks discussed in the paper. The thermoelectric system has reversive properties; therefore it can maintain the constant temperature +(5±1)°C all-the-year-round at the environment temperature (-40 +30)°C. The temperature balance in the thermostatic container of the pickup refrigerated truck VIS-2345 (VAZ2105) was studied. A possible technical solution of the thermoelectric cooling-heating unit for the pickup with the cooling power up to 240 W and the heating power about 285 W suggested. The average electric power supply for thermostatic control of the container during all-the-year-round is equal or even less than the power supply for a vapor-compression refrigerator with an additional electric heater.
