摘要： A system includes a first sensor that provides an output indicative of a sensed 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 system includes a second sensor that provides an output indicative of a sensed 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 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 pressure to the at least one target pressure value. The system includes a display that displays an indication of whether the level of refrigerant charge is at, above, or below an acceptable level.
