ABSTRACT:
A conventional centrifuge refrigeration system is modified by connecting a capillary sized line between the expansion valve and the evaporator. This permits the expansion valve to be located at a point within the centrifuge remote from the rotor. This facilitates the easy removal of the expansion valve for repair and yet reduces icing of the expansion valve. Further, the system capacity may be improved by wrapping the capillary line about the suction line to effect subcooling of the refrigerant before it passes to the evaporator. This enhances system capacity.
