Heat transfer modelling in a refrigerated display cabinet: The influence of operating conditions

► A rise in the ambient temperature leads to an increase in the air and the load temperatures at the front of the display cabinet. ► The influence of the radiative conditions is significant on the temperature of the front load. ► The increase in the internal infiltration rate leads to a decrease in the air and load temperatures in the bottom load. ► The increase in the external infiltration rate leads to an increase in the return air temperature.
