Abstract: A charge-verification system for a circuit including a condenser having an inlet, an outlet, and a coil circuit tube extending between the inlet and the outlet is provided. The charge-verification system may include a first of coil temperature sensor located on the coil circuit tube a first distance from the inlet and a second of coil temperature sensor located on the coil circuit tube a second distance from the inlet. The charge-verification system may also include a controller receiving a first signal from the first temperature sensor indicative of a first temperature and a second signal from the second temperature sensor indicative of a second temperature. The controller may determine which of the first signal and the second signal is closer to an actual saturated condensing temperature of the condenser.

Abstract: A system is provided and may include a compressor functioning in a refrigeration circuit. An ambient temperature sensor may produce a signal indicative of an ambient temperature. Processing circuitry may calculate an energy efficiency rating of the refrigeration circuit and may generate a relationship of the calculated energy efficiency rating and ambient temperature. The processing circuitry may compare the calculated energy efficiency rating to a base energy efficiency rating to determine if a fault condition exists.

Abstract: A system is provided and may include a refrigeration circuit having a condenser, a first sensor producing a signal indicative of a detected condenser temperature of the condenser, and processing circuitry in communication with the first sensor. The processing circuitry may determine a derived condenser temperature independent from information received from the first sensor and may compare the derived condenser temperature to the detected condenser temperature to determine a charge level of the refrigeration circuit.
