System and method for efficient isothermal compression

A system for isothermal compression, comprising:

• a heat exchange sub-system,
• at least one compression unit incorporated inside said heat exchange sub-system, said at least one compression unit containing an incompressible liquid medium and a working fluid medium in contact with said incompressible liquid medium,
• a compression mechanism operatively coupled to said incompressible liquid medium to displace a level thereof within said at least one compression unit to result in compression of said working fluid medium to a predetermined pressure value, wherein said compression of said working fluid medium generates heat,
• at least one discharge port actuated to discharge said working fluid medium from said at least one compression unit when said predetermined pressure value has been attained,
• at least one suction port actuated to enter said working fluid medium in said at least one compression unit,
• wherein said heat exchange sub-system contains a cooling medium circulating in a thermal coupling with at least one said compression unit to absorb the heat generated as the result of the compression and thus cooling the working fluid medium in said at least one compression unit to attain an isothermal compression, and
• a controller sub-system operatively coupled to said compression mechanism to control said level of said incompressible liquid medium in said at least one compression unit, to said at least one discharge port and said at least one suction port to control discharge and entrance of said working fluid medium passing from, and to said at least one compression unit, respectively.
