Latest Patents

Braun's latest patents reflect his focus on enhancing operational efficiency. One notable invention is a fuel cell system that provides high grade heat to an absorption chiller. This innovation involves the strategic modification of a standard phosphoric acid fuel cell power plant by removing its heat exchanger. This allows for a higher temperature coolant flow directed from the fuel cell stack to the generator of the absorption chiller, thereby improving its efficiency. This innovation can utilize either a double effect or single effect absorption chiller.

Another of his patents is the refrigerant charge adequacy gauge, which introduces a method for assessing the adequacy of refrigerant charge in an air conditioning system using just two temperature measurements. By sensing the temperature of the liquid refrigerant as it exits the condenser coil and measuring the temperature of the condenser coil itself, the difference between these measurements is calculated to indicate refrigerant charge sufficiency. This method includes refinements to eliminate transient measurement inaccuracies and signal noise, employing probability theory to establish a permissible threshold of deviation.
