    Patent number: 5317881
    Abstract: In order to cool food in a display compartment, a cold air stream is generated by refrigeration means, preferably a fan, an evaporator and a condenser, and is passed through the display compartment from its inlet to its outlet. The air temperatures at the inlet and outlet may be sensed by sensors in which case control means are responsive to a signal from the output of both the sensors and control the operation of the refrigeration means to maintain the air temperature in the display compartment within a narrow predetermined range.
