ABSTRACT:
An improved centrifugal refrigeration system having an elongated rotatably supported shaft with means to rotate the shaft, a condenser unit affixed to and rotated with the shaft, the condenser unit having a tubular member coiled about the shaft in a path beginning at a condenser unit inlet point at a first radius from the shaft and increasing as it is coiled about the shaft to an outlet point at a greater radius, an evaporator unit affixed to and rotated by the shaft and being spaced from the condenser unit, the evaporator unit having a tubular member coiled about the shaft in a path beginning with an inlet point adjacent the shaft and an outlet point at a second radius from the shaft, the second radius of the evaporator unit outlet point being less than or at least not substantially greater than the first radius of the condenser inlet point, a refrigeration return line connecting the evaporator outlet point to the condenser outlet point, a refrigerant delivery tube connecting the condenser outlet point to the evaporator inlet point, a metering device interposed in the refrigerant delivery tube, and refrigerant filling the condenser tubing, evaporator tubing, refrigeration return tube and refrigeration delivery tube in a closed hermetically sealed system. As the shaft is rotated the refrigerant is compressed in the condenser unit by centrifugal force into a liquid, the liquid passing through the metering device and into the evaporator unit where the liquid expands into gas, absorbing heat and the refrigerant gas is returned back to the condenser inlet point in a continuous cycle.
