Abstract

The autonomy time of an icelined solar powered vaccine cooler expresses the amount of hours the cooler is able to keep vaccines within an acceptable temperature range during low solar radiation conditions, i.e. when the compressor of the cooling system is idle. This study investigates how different parameters related to the cooler cabinet and ice storage affect the autonomy time. A dynamic model of the vaccine cooler cabinet including the ice storage was used for the investigation. The model was calibrated using measurements from three different experimental setups, and the calibrated model showed a good agreement with the measurements. The results show that the mass of ice in the storage was the most promising parameter to consider for prolonging the autonomy time. Furthermore, it was shown that reduction of the thermal bridges in the cabinet also is of great importance.
