Title: Awwad Nader: Innovator in Refrigerant Cycle Technology
Introduction: Awwad Nader, based in Baldwinsville, NY, is a notable inventor in the field of thermal management and refrigeration technologies. With a keen focus on enhancing the efficiency of refrigerant cycles, Nader has made a significant contribution to the industry through his innovative patent.
Latest Patents: Nader holds a patent titled "Refrigerant cycle with defrost termination control." This invention introduces a transient mode that facilitates the transition from a defrost cycle back to steady-state operation. The technology includes a mechanism that selects a default position for the expansion device when the defrost cycle concludes. At the end of the defrost cycle, the evaporator is hot, indicating that an increased flow of refrigerant through the expansion device may be counterproductive. To address this, Nader’s design features a control system that positions the expansion device in a defrost transient position, which effectively restricts refrigerant flow to a level below that dictated by the evaporator's high temperature. After a designated time following the end of the defrost mode, the refrigerant cycle can smoothly revert to steady-state operation.
Career Highlights: Awwad Nader is associated with Carrier Corporation, a leader in the heating, ventilation, and air conditioning industry.
