摘要： Provided is a cascade refrigeration system for a transport unit. The cascade refrigeration system has a first refrigeration cycle comprising a first compressor and a first expansion valve, a second refrigeration cycle comprising a second compressor and a second expansion valve, and a cascade heat exchanger. The cascade heat exchanger comprises a condenser side fluidically coupled downstream of the first compressor and upstream of the first expansion valve, and an evaporator side fluidically coupled downstream of the second expansion valve and upstream of the second compressor. The cascade refrigeration system also comprises a pre-cooler comprising a first side and a second side. The first side is fluidically coupled downstream of the first compressor and upstream of the condenser side of the cascade heat exchanger, and the pre-cooler is configured to transfer heat between refrigerant in the first side and refrigerant in the second side.

摘要： Provided is a refrigeration system for a transport unit. The refrigeration system has a refrigeration cycle comprising a compressor, an evaporator, a condenser fluidically coupled downstream of the compressor and upstream of the evaporator, an expansion valve fluidically coupled downstream of the condenser and upstream of the evaporator, and a suction gas heat exchanger comprising a liquid line side and a suction line side. The liquid line side is fluidically coupled downstream of the condenser and upstream of the expansion valve, and the suction line side is fluidically coupled downstream of the evaporator and upstream of the compressor. The suction gas heat exchanger is configured to transfer heat between refrigerant in the liquid line side and refrigerant in the suction line side.

摘要： Provided is a heat exchanger arrangement for a refrigeration system. The heat exchanger arrangement comprises a heat exchanger having a first flow path, a second flow path, and a heat exchange interface that is configured to transfer heat between a first fluid in the first flow path and a second fluid in the second flow path, in use. The heat exchanger arrangement also comprises an inlet arrangement having a first-fluid inlet for receiving the first fluid from a source, a first opening into the first flow path, and a second opening into the first flow path. The inlet arrangement is operable to control flow of the first fluid from the first-fluid inlet to the first opening and to the second opening.
