ABSTRACT:
A d.c. motor together with a hot gas bypass valve is incorporated into a cooling system specifically designed for removing heat from computer systems. Unlike typical refrigeration systems, the cooling system herein runs continuously and responds to changes in thermal load. This allows the unit to operate within a wide range of ambient conditions and at various thermal load levels unlike other systems which were capable of operation only at a single, predesigned load level. The cooling system is modular and is easily added to or removed from a redundant system which includes a single evaporator with multiple refrigerant loops which provides yet another aspect of continuous operation due to the inherent redundancy thus provided.
