Portable self-contained power and cooling system

A portable power and cooling system comprising:

• a drive unit including a combustion section, a scroll-type expander section, a scroll-type air compressor section, and a power output drive shaft, said expander and air compressor sections connected together for synchronous movement via said power output drive shaft;
• said combustion section including a combustion air inlet and a combustion gas outlet, said scroll-type expander section including at least one pair of meshed axially extending involute spiral wrap members having involute centers and defining at least one expansion chamber between them that moves radially between an expander inlet zone, which is in fluid communication with the combustion gas outlet, and an outlet zone when one wrap member is orbited along a circular path about an orbit center relative to the other wrap member, said scroll type air compressor section including at least one pair of meshed axially extending involute spiral wrap members having involute centers and defining at least one compression chamber between them that moves radially between a compressor inlet zone and an outlet zone, which is in fluid communication with the combustion air inlet of the combustion section, when one wrap member is orbited along a circular path relative to the other wrap member about an orbit radius, said drive connecting unit integrally connecting said one wrap member of each of said scroll-type expander and air compressor sections;
• means for causing combustion within said combustion chamber such that the products of combustion flow from said combustion chamber, through said combustion gas outlet and into said expander inlet zone, into said at least one expansion chamber to cause said one wrap member of said scroll-type expander section to orbit along with said one wrap member of said scroll-type compressor section such that the products of combustion are expanded by said scroll-type expander section and exhausted out said expander outlet, air is drawn into said air compressor inlet zone, compressed within said at least one compression chamber, expelled through said air compressor outlet zone, and delivered to said combustion chamber and said power output shaft is rotated;
• a refrigeration system including a refrigerant compressor connected in drive relationship with the output drive shaft, a refrigerant condenser, a refrigerant expansion valve and a refrigerant evaporator, and a conduit containing a refrigerant in fluid communication with the compressor, condenser, expansion valve, and evaporator.
