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.
