Title:
BINARY WORKING MEDIUM HEAT ENERGY POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/257444
Kind Code:
A1
Abstract:
A binary working medium heat energy power device, relating to the technical fields of engineering thermophysics and energy saving, and comprising a cylinder and a piston. The upper and lower ends of the cylinder are closed; the piston is provided in an upper space in the cylinder in such a manner that the piston can be moved vertically; in the cylinder, a heat exchanger is provided below the piston; the heat exchanger is provided with an inlet and an outlet to be communicated with the outside; a binary working medium solution is injected into the cylinder to be in contact with the heat exchanger for heat exchange; when a hot working medium is injected into the heat exchanger, the binary working medium absorbs heat and releases gas to push the piston upward; and when a cold working medium is injected into the heat exchanger, the binary working medium releases heat to cool down and absorbs the condensation heat of the gas to enable the piston to move downward. The present device has the advantages of simple structure, low power consumption and little cooling liquid, high reliability, etc.; and the heat exchanger works in an alternate heat exchange process of variable temperature heating and variable temperature cooling, and delayed switching is used between heating and cooling, such that the latent heat of gasification of the binary working medium and the heat released by the change of a saturation temperature can be recovered and reused.
