  • Switchable two-stage and cascade marine energy-saving ultralow-temperature refrigeration system
    Patent number: 10107526
    Abstract: The present invention discloses a switchable two-stage and cascade marine energy-saving ultralow-temperature refrigeration system which comprises a high-temperature level refrigeration system, a low-temperature level refrigeration system, a hot fluorine defrosting system of a high-temperature level air cooler and a hot fluorine defrosting system of a low-temperature level air cooler. The hot fluorine defrosting system of the high-temperature level air cooler comprises a high-temperature level compressor of which the outlet is divided into two paths through a first oil separator; and the second path is connected with an air suction port of the high-temperature level compressor through a first solenoid valve, the high-temperature level air cooler, a third solenoid valve, a first pressure relief valve, a first gas-liquid separator, a first one-way valve and a first heat regenerator.
