  • Patent number: 10569620
    Abstract: A refrigeration system includes a startup mode control module that receives an off time of a compressor of the refrigeration system and an ambient temperature, determines whether the off time and the ambient temperature indicate that the compressor is in a flooded condition, and selects, based on the determination, between a normal startup mode and a flooded 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, in the flooded startup mode in response to the startup mode control module selecting the flooded startup mode, and transitions from the flooded startup mode to the normal startup mode after a predetermined period associated with operating in the flooded startup mode. The compressor is operated at a first speed in the normal startup mode and at a second speed in the flooded startup mode.

  • Patent number: 10532632
    Abstract: 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.

  • Patent number: 10414241
    Abstract: A refrigeration system may include a compressor, a first heat exchanger, a first working fluid flow path, and a second working fluid flow path. The first heat exchanger receives working fluid discharged from the compressor. The first working fluid flow path may receive working fluid from the first heat exchanger and may include an evaporator and an evaporator control valve that is movable between a first position allowing fluid flow through the evaporator and a second position restricting fluid flow through the evaporator. The second working fluid flow path may receive working fluid from the first heat exchanger and may include a eutectic plate and a plate control valve that is movable between a first position allowing fluid flow through the eutectic plate and a second position restricting fluid flow through the eutectic plate.

  • Patent number: 10328771
    Abstract: A compressor compresses a refrigerant. A eutectic plate cools a refrigerated space. An evaporator cools the refrigerated space. A mixture of the refrigerant and an oil flows through the evaporator and the eutectic plate. A control module controls the compressor, a first valve that permits or prevents flow of the mixture to the eutectic plate, and a second valve that permits or prevents flow of the mixture to the evaporator. In response to a temperature of the refrigerated space being greater than a predetermined temperature, the control module: increases a speed of the compressor; operates the compressor at the increased speed for a predetermined time period; after the predetermined period: opens the second valve; and closes the first valve, where the control module opens the second valve before closing the first valve, and decreases the speed of the compressor after closing the first valve.

  • Patent number: 9876346
    Abstract: A refrigerant compressor includes an electric motor. A current sensor measures current to the electric motor. A switching device is configured to close and open to allow and prevent current flow to the electric motor, respectively. A maximum continuous current (MCC) device generates an output that one of: (i) is an MCC for the electric motor and (ii) is a value indicative of the MCC for the electric motor. A motor protection module: is remote from the MCC device; receives the output wirelessly from the MCC device via an antenna; one of sets a first MCC to the MCC for the electric motor and determines the first MCC based on the value indicative of the MCC for the electric motor; selectively sets a predetermined MCC to the first MCC; and controls the switching device based on a comparison of the current to the electric motor and the predetermined MCC.
