Description
Turbomachinery based cooling systems have advantages compared to other cooling systems in terms of low maintenance due to the oil-free gas bearing, low micro-vibration emission as they are continuous flow machines with well-balanced rotor, and the low specific energy consumption (W per W of cooling) due to their high efficiency. In a first concept, they are applied as turbo compressor and turbo expander in Reverse Turbo-Brayton (RTB) cryocoolers. The load heat exchanger (i.e. the cold head) of RTB cryocoolers can be mechanically connected to the HTS as for any other cryocooler. In a second concept, if a central cryo plant is available, i.e. if cold temperatures are already generated with a separate cryocooler, turbo compressors can distribute the cooling capacity via circulating cold helium (or other gases) to the HTS location. The gas-bearing turbo compressor operates as a cold compressor or a cryo fan. Again, at the application, a load heat exchanger can mechanically connect to the HTS or the helium can directly cool the HTS. Celeroton’s gas bearing and motor/generator technology allows for operation of the turbomachinery fully immersed in the cold zone, without requiring a flanged solution and therefore giving more flexibility to the cold box design and allowing for higher package density in the cold box.
