Power generation-refrigeration system

Abstract

A power generation-refrigeration system comprising a refrigerant boiler, and a primary turbine for extracting energy from the refrigerant. The system also comprises a reversible turbomachine having a compressor mode of operation for compressing refrigerant passing therethrough and a turbine mode of operation for extracting further energy from the refrigerant; a first flow path in communication with the primary turbine, the reversible turbomachine, and a condenser; a second flow path in communication with the primary turbine, the reversible turbomachine, the condenser, and an evaporator; and means for directing refrigerant through the first flow path when the reversible turbomachine is in the turbine mode and through the second flow path when the reversible turbomachine is in the compressor mode. Power means is provided for generating power, a first connecting means is provided for connecting the reversible turbomachine and the power means and having a power generation position wherein energy extracted from refrigerant by the reversible turbomachine is used to generate power; and a second connecting means is provided for connecting the primary turbine and the reversible turbomachine and having a refrigeration position wherein energy extracted from refrigerant by the primary turbine is transmitted to the reversible turbomachine to compress refrigerant passing therethrough, and a power generation position wherein energy extracted from the refrigerant by the primary turbine is transmitted to the reversible turbomachine to assist the generation of the power.
