摘要： A refrigeration system includes a startup mode control module that receives at least one parameter associated with operation of a compressor of the refrigeration system, determines whether the at least one parameter indicates that the compressor is in a high ambient temperature startup condition, and selects, based on the determination, between a normal startup mode and a high ambient temperature startup mode. A compressor control module operates the compressor in the normal startup mode in response to the startup mode control module selecting the normal startup mode, operates the compressor in the high ambient temperature startup mode in response to the startup mode control module selecting the high ambient temperature startup mode, and transitions from the high ambient temperature startup mode to the normal startup mode after a predetermined period associated with operating in the high ambient temperature startup mode.

摘要： Provided is an air conditioning apparatus that is capable of suppressing increases in volume and cost of the apparatus and performing more suitable overheating protection. An electric compressor is an inverter-integrated electric compressor integrally including a compressor, an electric motor that drives the compressor, and an inverter including a temperature sensor that detects the temperature in the vicinity of a semiconductor switching device, wherein a controller estimates a discharge temperature of the compressor on the basis of a correlation of respective pressure loading characteristics for the detected temperature of the inverter, for the rotational speed of the compressor, and for the motive force of the compressor in a refrigerating cycle.

摘要： A capacity control algorithm for a multiple compressor liquid chiller system is provided wherein the speed and number of compressors in operation are controlled in order to obtain a leaving liquid temperature setpoint. In response to an increase in the load in the chiller system, the algorithm determines if a compressor should be started and adjusts the operating speed of all operating compressors when an additional compressor is started. In response to a decrease in the load in the chiller system with multiple compressors operating, the algorithm determines if a compressor should be de-energized and adjusts the operating speed of all remaining operating compressors when a compressor is de-energized.

摘要： A subcooling controller includes a sensor and a processor. The sensor measures one or more of a temperature external to a first heat exchanger that removes heat from carbon dioxide refrigerant, a temperature of the carbon dioxide refrigerant, and a pressure of the carbon dioxide refrigerant. The processor determines that one or more of the measured temperature external to the first heat exchanger, the temperature of the carbon dioxide refrigerant, and the pressure of the carbon dioxide refrigerant is above a threshold and in response to that determination, activates a subcooling system. The subcooling system includes a condenser, a second heat exchanger, and a compressor. The condenser removes heat from a second refrigerant. The second heat removes heat from the carbon dioxide refrigerant stored in a flash tank. The compressor compresses the second refrigerant from the second heat exchanger and sends the second refrigerant to the condenser.

摘要： According to certain embodiments, a refrigeration system comprises first and second evaporators, first and second compressors, and a gas cooler. The first and second evaporators receive liquid refrigerant from a flash tank and evaporate the refrigerant to cool a first case and a second case, respectively. The second case has a higher temperature set point than the first case. The first compressor compresses the refrigerant discharged from the first evaporator. The second compressor compresses the refrigerant discharged from the first compressor, flash gas from the flash tank, and the refrigerant discharged from the second evaporator. The gas cooler comprises an air-cooled stage that cools the refrigerant discharged from the second compressor and an evaporative stage that cools the refrigerant discharged from the air-cooled stage. The gas cooler further comprises an outlet that supplies the cooled refrigerant to the flash tank through an expansion valve.
