Abstract: An HVAC system includes a compressor, condenser, and evaporator. A sensor measures a value associated with the refrigerant in the condenser or the evaporator, and a controller is communicatively coupled to the compressor and the sensor. The controller determines, based on an operational history the compressor, that pre-requisite criteria are satisfied for entering a sensor validation mode. After determining the pre-requisite criteria are satisfied, an initial sensor measurement value is determined. Following determining the initial sensor measurement value, the compressor is operated according to a sensor-validation mode. Following operating the compressor according to the sensor-validation mode for at least a minimum time, a current sensor measurement value is determined. The controller determines whether validation criteria are satisfied for the current sensor value. In response to determining that the validation criteria are satisfied, the controller determines that the sensor is validated.

Abstract: An HVAC system includes a variable-speed compressor which compresses refrigerant flowing through the HVAC system, a blower which provides a flow of air through the HVAC system at a controllable flow rate, and a controller communicatively coupled to the variable-speed compressor and the blower. The controller receives a demand request, which includes a command to operate the HVAC system at a predefined setpoint temperature. In response to receiving the demand request, a setpoint temperature associated with the HVAC system can be adjusted to the predefined setpoint temperature. A speed of the variable-speed compressor is decreased to a low-speed setting. Based on the decreased speed of the variable-speed compressor, an air-flow rate can be determined to provide by the blower. The controllable flow rate of the flow of air provided by the blower can be adjusted based on the determined air-flow rate.

Abstract: A climate-control system includes a variable-capacity compressor. An outdoor ambient temperature sensor indicates a temperature of the outdoor ambient air. A return air temperature sensor indicates a temperature of the return air in the system. A controller commands a startup compressor stage based on the temperature from the outdoor ambient temperature sensor and commands a running compressor stage based on a time-based slope of the temperature from the return air temperature sensor and the startup compressor stage.

Abstract: A combined suction header and accumulator for a refrigeration system is described that may protect a compressor from refrigerant liquid entering the compressor while reducing superheat used to evaporate the refrigerant. The combined suction header and accumulator unit for a refrigeration system includes a suction header coupled to an exit side of an evaporator. The suction header includes a main body and receives a flow of refrigerant from the evaporator. The flow of refrigerant includes a liquid portion and a vapor portion. The combined suction header and accumulator unit includes a liquid accumulator disposed within the main body of the suction header. The liquid accumulator blocks the liquid portion of the flow of refrigerant from exiting the main body.
