System and method of controlling temperature of a medium by refrigerant vaporization and working gas condensation

A system to control a temperature of a medium by working gas condensation, comprising:

• a container having an exterior and an interior;
• at least one working gas reservoir associated with the container, the at least one working gas reservoir having at least one reservoir section configured to hold working gas, each at least one reservoir section having a wall with an exterior surface structured to be thermally coupled with a volume of the medium in the container and to provide thermal change to the volume of the medium in the container and thereby provide a volume of medium thermal coverage in the container, the volume of medium thermal coverage having an outside boundary;
• a condensation apparatus to provide regulation of working gas pressure in the at least one working gas reservoir;
• wherein the at least one working gas reservoir is configured to form a vapor space in each of the at least one reservoir sections in response to receiving working gas and in response to the condensation apparatus regulation of the working gas pressure to enable working gas condensation at or near a selected temperature of the volume of medium thermal coverage for the volume of the medium in the container that is thermally coupled to the respective at least one reservoir section;
• and
• wherein the at least one reservoir section comprises a plurality of reservoir sections that each have a respective internal reservoir space that is in fluid communication with at least one other internal reservoir space of an adjacent reservoir section, and the plurality of reservoir sections are arranged in spaced relationship to adjacent reservoir sections with the respective volumes of medium thermal coverage having the respective boundaries of thermal coverage to be at least contiguous.
