Latest Patents

Zaher’s latest patents include a heat engine and a pumping apparatus. The heat engine patent describes a system that comprises a heat exchanger to transfer heat from a heat source to a working fluid. It features a positive displacement expander that receives inlet working fluid from the heat exchanger and discharges expanded working fluid as a multiphase fluid. This design allows for an overall volumetric expansion ratio that is a function of the inlet dryness of the working fluid. Additionally, a variable expansion valve is integrated to introduce a variable pressure drop in the working fluid, which helps maintain the overall volumetric expansion ratio. The controller is configured to adjust the valve to compensate for variable heat transfer to or from the working fluid.

The pumping apparatus patent outlines a system for a heat engine that includes an extraction line designed to extract a fraction of liquid working fluid from the working circuit. It features an extraction line pump for pumping the extracted working fluid and an extraction line heat exchanger for vaporizing it. The pressure-operated pump circulates the working fluid around the working circuit, with the extraction line pump and heat exchanger arranged in series to convert the liquid working fluid into a pressurized motive gas.
