Wilson, R

This patent describes an auxiliary outside air refrigerating means for a refrigerated storage room such as a cooler or the like comprising: a heat exchanger having two pairs of inlets and outlets for receiving and re-circulating air supplies from two separate sources and a heat exchange means for transferring heat between the two air supplies without admixing the two air supplies. A first inlet and outlet are connected to the air in the storage room, a second inlet is connected to a source of outside air; a storage room air fan for re-circulating storage room air through the heat exchanger, an outside air fan for circulating outside air through the heat exchanger; and control means for automatically actuating the storage room air fan and outside air fan. The fans are activated whenever both the cooler temperature rises to a first predetermined temperature indicative of an upper storage room limit and the outside air temperature is no greater than a second predetermined temperature below the upper storage room limit.
