1. A refrigeration cycle intercooler with dual coil evaporator comprising:
a main refrigerant feed line comprising a first length of conduit, pipe, or tubing having a feed line first end and a feed line second end;
a thermal expansion valve connected to the feed line first end;
an inner coil evaporator comprising:
a second length of conduit, pipe, or tubing shaped into a first coil or helical shape and having an inner coil first end and an inner coil second end, and
an inner coil input tube having an inner coil input tube first end connected to the feed line second end and an inner coil input tube second end connected to the inner coil first end;
an outer coil evaporator comprising:
a third length of conduit, pipe, or tubing shaped into a second coil or helical shape and having an outer coil first end and an outer coil second end, and
an outer coil input tube having an outer coil input tube first end connected to the feed line second end and an outer coil input tube second end connected to the outer coil first end;
a main refrigerant return line comprising a fourth length of conduit, pipe, or tubing having a return line first end connected to the inner coil second end and the outer coil second end and a return line second end; and
a cylindrical housing positioned over the inner coil evaporator and the outer coil evaporator with a housing first end adjacent to the inner coil first end and the outer coil first end, and a housing second end adjacent to the inner coil second end and the outer coil second end.
