Thermo-transformation method for heating and cooling purposes in thermodynamic cycle, involves filling expansion cylinder with expansion liquid e.g. carbon dioxide suitable for usable temperature range

摘要

The thermo-transformation method involves filling an expansion cylinder (2) with an expansion liquid (5) e.g. carbon dioxide suitable for the usable temperature range. The expansion fluid from the heat exchanger is heated by energy supply for the expansion or is cooled by energy discharge (8) for the contraction. A piston (4) with its front surface is configured such that a compression cylinder (3) provides the required counter-pressure. The compression cylinder is filled with compression liquid, such as argon.
