Abstract Of The Disclosure Rotary closed Rankine cycle cooling and heating apparatus utilizing a single fluid for both engine power and refrigeration. The apparatus includes a rotary housing containing a boiler, power fluid expander coupled with a refrigerant fluid compressor and a refrigerant expander. A condenser for the expanded power portion and the compressed refrigerant portion of the single fluid, and an evaporator for the expanded refrigerant fluid por- tion, are mounted at respectively opposite sides of the housing coaxially thereof for rotation with the housing as a unit. The power fluid expander is driven at a predetermined speed by pres- sure power fluid vapor generated in the boiler and in turn drives the refrigerant fluid compressor. The refrigerant expander is of the capillary type constructed and arranged with respect to the evaporator to automatically control the capacity balance of the refrigerant system. The entire unit is hermetically sealed and the Rankine cycle power system is adapted and designed for use with a high molecular weight fluid. The expanded power and com- pressed refrigerant portions of the single fluid are condensed in the condenser and means are provided in the housing for dividing and supplying the condensed liquid to the boiler at the rate to maintain a constant predetermined liquid level in the boiler and to the refrigerant expander to establish and maintain capacity balance in the refrigerant system.
