ABSTRACT:
Herein disclosed is an improved cooling/heating unit incorporated with an automative air conditioner. The unit achieves quick freezing of ice cubes by stopping operation of an electric fan for a predetermined time. The electric fan is located in a refrigerated compartment through which a portion of an evaporator, which also passes through a freezer compartment, is arranged. By suppressing the operation of the fan, the total heat transfer capacity of the system can be directed toward increasing the cooling capacity in the freezer compartment.
