Abstract: When the temperatures of outdoor heat exchangers 23a and 23b detected by outdoor heat exchanger temperature sensors 57a and 57b become equal to or higher than 5 degrees C. and the sucking superheating degrees of compressors 21a and 21b become equal to or lower than 0 degrees C. while an air conditioning apparatus 1 is performing the reverse defrosting operation, the reverse defrosting operation is stopped and the heating dominant operation is resumed. At this time, the total operating times of the compressors 21a and 21b are reset. The sucking superheating degrees of the compressors 21a and 21b are obtained by subtracting the low pressure saturation temperatures calculated from the sucking pressures of the compressors 21a and 21b, from the temperatures of the refrigerants sucked into the compressors 21a and 21b which temperatures are detected by the sucking temperature sensors 54a and 54b.

Abstract: A refrigerant recovery system includes a first oil separator including a chamber configured to receive refrigerant from an air conditioning system, a heat exchanger disposed within the first oil separator, and a compressor fluidly connected to the chamber and the heat exchanger. A first valve is disposed in a first flow line that is fluidly connected between an inlet of the first oil separator and a source of refrigerant and a second valve is disposed in a second flow line that fluidly connects the compressor and the heat exchanger. A controller is configured to open the first valve to enable refrigerant to pass into the chamber of the first oil separator, open the second valve so that a flow loop for refrigerant is formed between the heat exchanger and the compressor, activate the compressor to heat the refrigerant flowing through the flow loop, and subsequently commence a refrigerant recovery operation.

Abstract: An industrial refrigeration system has a purger for removing non-condensable content extracted from a volume of refrigerant. The purger separates a quantity of refrigerant from a mixture of refrigerant and air and purges the air and a portion of the refrigerant. The purger includes a control unit and an algorithm that estimates the purged quantity of refrigerant from measured and stored refrigeration and purger operating parameters.
