Patent number: 8810419Abstract: An exemplary embodiment of a refrigerant charge monitoring system includes first and second sensors. The first sensor is operable for sensing temperature of a liquid refrigerant line that is connected to, within, or extending from an outlet of a condenser. The second sensor is operable for sensing pressure of the liquid refrigerant line. A controller is configured to determine at least one target pressure value from the sensed temperature of the liquid refrigerant line. The controller is configured to determine if the level of refrigerant charge is at, above or below an acceptable level based on a comparison of the sensed pressure of the liquid refrigerant line to the at least one target pressure value.Type: GrantFiled: February 6, 2014Date of Patent: August 19, 2014Assignee: Emerson Electric Co.Inventors: Amr E. Gado, Thomas J. Fredricks, Thomas B. Lorenz, Edward B. Evans

Patent number: 8648729Abstract: An exemplary embodiment of a system includes first and second sensors. The first sensor is operable to provide an output indicative of a sensed refrigerant liquid temperature of a liquid refrigerant line that is within or extending from an outlet of a condenser coil of an air conditioner or heat pump unit. The second sensor is operable to provide an output indicative of a sensed refrigerant liquid pressure in the liquid refrigerant line. A controller is configured to determine at least one target pressure value from the output indicative of the sensed refrigerant liquid temperature of the liquid refrigerant line. The controller is configured to determine if the level of refrigerant charge is at, above, or below an acceptable level based on a comparison of the output indicative of sensed refrigerant liquid pressure to the at least one target pressure value.Type: GrantFiled: June 14, 2013Date of Patent: February 11, 2014Assignee: Emerson Electric Co.Inventors: Amr E.
