Abstract:
A refrigeration system comprising:an intermediate slurry tank for a refrigerant vapor and a slurry of solid sublimatable refrigerant particles in a liquid having a first outlet for outflow of the slurry, a second outlet for outflow of the vapor, and a first inlet for receiving the refrigerant; an evaporator having an inlet and an outlet; a first conduit connecting the first outlet of the intermediate slurry tank and the evaporator inlet; a compression system having a first low pressure inlet and second intermediate pressure inlet, and having a high pressure outlet; a second conduit connecting the evaporator outlet and the first low pressure inlet of the compression system; a third conduit connecting the second outlet of the intermediate slurry tank and the second intermediate pressure inlet of the compression system; a condenser having a condenser inlet and a condenser outlet; a fourth conduit connecting the compression system outlet and the condenser inlet; a condenser receiving tank having an inlet for receiving refrigerant and an outlet for receiving refrigerant; a fifth conduit connecting the condenser outlet and the condenser receiving tank inlet; and a sixth conduit connecting the condenser receiving tank outlet to the first inlet of the intermediate slurry tank.
