Abstract: A refrigeration system including a condenser, a compressor, a first transportation system passing refrigerant between the compressor and the condenser, a first evaporator, a second evaporator, a second transportation system passing the refrigerant between the condenser and a holding vessel, with the holding vessel including refrigerant in gas and liquid form, a third transportation system passing the refrigerant between the holding vessel and a pump, a fourth transportation system passing the refrigerant between the pump and the first evaporator, a fifth transportation system passing the refrigerant between the pump and the second evaporator, and a heat exchanger wherein the refrigerant in the second transportation system exchanges heat with the refrigerant in the fifth transportation system to heat the refrigerant in the fifth transportation system before the refrigerant passes to the second evaporator.

Abstract: A fluid transport system including a fluid transfer assembly, an air dryer and a tube. The fluid transfer assembly includes a pipe for transporting a cold fluid and a vapor barrier surrounding the pipe. The air dryer removes moisture in the air. The tube is connected to the air dryer and the fluid transfer assembly. The tube transfers air from the air dryer to the fluid transfer assembly at a plurality of points along a length of the fluid transfer assembly.
