Thermoelectric plate Were used cooling foam box, no packing foam inside the box 15l by starting temperature was 30 ° c over time to lower the temperature inside a foam box, as shown in Table 3.1.
Plates, Thermoelectric cooling is applied within the foam box packed with no 15L size by default temperature inside the foam box equal to 30° C internal temperature over time, the foam box are reduced, as shown in table 3.1.
The Thermoelectric is used to cool the internal foam box is not a container size 15 L by starting temperature inside the box with foam as much as 30 °C over time. temperature within the box is the decrease in foam as shown in the table 3.1.
