Rotary engine powered heating and cooling appts. - uses separate power and refrigerant fluids in closed Rankine cycle

摘要

The apparatus includes a rotary boiler, power fluid expander and condenser coupled with a refrigerant compressor, refrigerant expander and refrigerant evaporator. The components are on a common axis with the boiler, power fluid expander, refrigerant compressor and expander compactly arranged in a housing between the condenser and evaporator. The housing, condenser and evaporator are mounted for coaxial rotation together as a unit. The power fluid expander is driven by pressure power fluid generated in the boiler and in turn drives the refrigerant fluid compressor. The refrigerant expander is of the capillary type and automatically controls the capacity balance of the refrigerant system.
