Abstract
A dynamic refrigeration system may include an ultrasonic transducer attached to a refrigerant flow sight glass, an expansion valve, and an evaporator coil in a refrigerant line. The ultrasonic transducer may be placed in a refrigerant flow of the refrigerant line before or after the expansion valve and before the evaporator coil, wherein sound waves of the ultrasonic transducer may break up large globules of refrigerant molecules into smaller globules of refrigerant molecules, thereby increasing total surface area of the refrigerant molecules to increase heat transfer capacity and total system efficiency. The system may provide 3-5 percent higher efficiency overall due to the presence of the ultrasonic transducer in the refrigerant line before or after the expansion valve.
