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 compressor is provided and may include a shell, a compression mechanism, a motor, and a diagnostic system that determines a system condition. The diagnostic system may include a processor and a memory and may predict a severity level of the system condition based on at least one of a sequence of historical-fault events and a combination of the types of the historical-fault events.

Abstract: A climate-control system includes a variable-capacity compressor unit operable in a first capacity mode and in a second capacity mode that is higher than the first capacity mode and a control module configured to (i) switch the variable-capacity compressor unit between the first capacity mode and the second capacity mode based on a demand signal, a current outdoor air temperature, and an outdoor-air-temperature slope, (ii) select a region based on a first comparison of at least one outdoor-air-temperature value with a predetermined outdoor-air-temperature range and a second comparison of at least one outdoor-relative-humidity value with a predetermined outdoor-relative-humidity range, and (iii) set at least one system operating parameter based on the selected region, the at least one system operating parameter including at least one of a high-capacity runtime of the variable-capacity compressor unit, a low-capacity runtime of the variable-capacity compressor unit, and a fan speed.

Abstract: A system includes a compressor and a controller. The controller operates the compressor in a flooded-start control mode. The flooded start control mode includes operating the compressor according to at least one cycle including a first time period during which the compressor is on, followed by a second time period during which the compressor is off. The controller determines at least one of the first time period, the second time period, and a number of cycles for the flooded-start control mode. At least one of the first time period, the second time period, and the number of cycles is based on received asset data corresponding to at least one of a type and a characteristic of at least one component of the refrigeration system. The controller operates the compressor in the flooded-start control mode after determining the first time period, the second time period, and the number of cycles.

Abstract: A system and method for flooded start control of a compressor for a refrigeration system is provided. A temperature sensor generates temperature data corresponding to at least one of a compressor temperature and an ambient temperature. A control module receives the temperature data, determines an off-time period since the compressor was last on, determines an amount of liquid present in the compressor based on the temperature data and the off-time period, compares the amount of liquid with a predetermined threshold, and, when the amount of liquid is greater than the predetermined threshold, operates the compressor according to at least one cycle including a first time period during which the compressor is on and a second time period during which the compressor is off.
