Latest Patents

Patricia holds a patent for a "Frost detection system for refrigeration apparatus." This invention includes an apparatus designed to detect frost buildup on an evaporator of a refrigeration system. The system utilizes an air velocity sensor connected to an analog to digital converter, which delivers binary signals representative of air velocity to a microcomputer. The microcomputer is programmed to prompt an operator to input an air flow reduction factor, which is then used to calculate a defrost initiation value. When the air velocity sensed is no longer greater than this value, the microcomputer generates a defrost initiation signal. This innovative approach enhances the operational efficiency of refrigeration systems.
