Latest Patents

The provided information lists one patent for Cheng: Method and Apparatus for Waste Heat Recovery and Absorption Gases Used as Working Fluid Therein. The invention describes a system that uses a low-temperature heat source to drive a thermodynamic cycle. Heat exchange in a regenerator separates an absorbed agent, such as ammonia or carbon dioxide, from a salt-based absorbent and produces a superheated, high-pressure vapor. The vapor expands through a turbine to generate power, then returns at lower pressure to the absorption stage, where it combines with the absorbent for reuse in the cycle. Cheng is credited with 1 patent.
