    Abstract: A system and method for calculating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. An evaporator sensor outputs an evaporator signal corresponding to at least one of an evaporator pressure and an evaporator temperature. An inverter drive modulates electric power delivered to the compressor to modulate a speed of the compressor. The control module is connected to the inverter drive and receives the evaporator signal, monitors electrical power data and compressor speed data from said inverter drive, and calculates at least one of a condenser temperature and a condenser pressure based on the evaporator signal, the electrical power data, and the compressor speed data.

    Abstract: A system and method for calibrating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. A condenser sensor outputs a condenser signal corresponding to at least one of a sensed condenser pressure and a sensed condenser temperature. An inverter drive modulates a frequency of electric power delivered to the compressor to modulate a speed of the compressor. A control module is connected to the inverter drive and determines a measured condenser temperature based on the condenser signal, monitors electric power data and compressor speed data from the inverter drive, calculates a derived condenser temperature based on the electric power data, the compressor speed data, and compressor map data for the compressor, compares the measured condenser temperature with the derived condenser temperature, and updates the compressor map data based on the comparison.

    Abstract: A system and method for monitoring an overheat condition of a compressor is provided. A compressor connected to an evaporator. A suction sensor outputs a suction signal corresponding to a temperature of refrigerant entering the compressor. A control module is connected to the evaporator sensor and the suction sensor and determines an evaporator temperature, calculates a suction superheat temperature based on the evaporator temperature and the suction signal, and monitors an overheat condition of the compressor by comparing the suction superheat with a predetermined suction superheat threshold.
