Title: Innovations of Earl M. Clark in Refrigeration Technology
Introduction
Earl M. Clark is a notable inventor based in Newark, DE (US). He has made significant contributions to the field of refrigeration technology. His innovative approach focuses on improving the efficiency of refrigeration systems by addressing the issue of non-condensible gaseous contaminants.
Latest Patents
Earl M. Clark holds a patent for a "Method and apparatus for removal of gas from refrigeration system." This patent describes an improved process for separating and removing non-condensible gaseous contaminants, such as nitrogen and oxygen, from conventional halocarbon vapor compression refrigeration systems. The method involves withdrawing a vapor stream above liquified refrigerant exiting the condenser on the high-pressure side of the expansion valve. This vapor is then processed through a second compression step, followed by condensation into a receiver. The liquid halocarbon from the receiver is returned to the evaporator, while the vapor phase is sent to a semipermeable membrane separation unit. The halocarbon enriched effluent from this unit is recycled to the inlet side of the second compressor, while the non-condensible contaminant enriched stream is vented from the refrigeration system. This high-pressure purge loop effectively removes non-condensible gases with minimal halocarbon refrigerant loss.
