  • 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.
