Title:
SUPERCRITICAL FLUID POWER SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/078566
Kind Code:
A1
Abstract:
A supercritical fluid power system comprises a power cycle loop (10) filled with a supercritical fluid working substance. The power cycle loop (10) comprises a first pressure container (11), a second pressure container (12), and a driven portion (13) disposed between the two pressure containers that are connected; and further comprises a hot source (20) and a cold source (30), wherein the hot source (20) is used to provide thermal energy to a working substance in one pressure container, and the cold source (30) is used to cool the working substance in another pressure container, so as to form a pressure difference between the two pressure containers. The working substance flows between the two pressure containers under the effect of the pressure difference and flows to the driven portion (13), so as to provide power to the driven portion (13). For this power system, a supercritical fluid working substance is heated and cooled in place of a conventional booster pump to form a pressure difference, and by switching pressure containers under the effects of a hot source and a cold source, a pressure difference is cyclically produced between the two pressure containers, thereby implementing recycling of power.
