The cooling system is a closed cycle system.

For this closed cycle system, vast heat of exhaust could be used efficiently and energy needed in the gasification could be reduced.
A similar T 2 term can be observed for 46 K < T < 90 K performed in a subsequent cooldown in a closed cycle system, as shown in Figure 5.
The state's proposal for protection of the fish, developed by the staff of the Department of Environmental Conservation with the backing of Riverkeeper, the environmental organization, was put forward as an alternative to forcing the company to shift from its current "once through cooling" system to a closed cycle system.
Pancake units made by the HTS tapes are prepared for stacking assembly to form the HTS magnet having a closed cycle cooling system for its practical operation.
A 10-K closed cycle refrigerator system, from Janis Research Company (Wilmington, MA, USA), was used together with a Keithley electrometer model 6517B (Keithley Instruments Inc., Cleveland, OH, USA) in order to measure the current-voltage (I-V) curves as a function of temperature.
For a closed wind tunnel, the setting of the operation points for testing requires special attention, and some similarity to closed cycle gas turbine systems exists.
This paper deals with dynamic modeling of both the nuclear and the conventional part of a combined heat and power plant coproducing steam for industrial use, based on a HTGR and a closed cycle gas turbine system.
The thermal transport measurements were performed in closed cycle refrigerator (CCR) system with a shielding box, as shown in Figure 2a, which helped maintain the temperature in the range of 20 to 300 K and provided a high-vacuum (approximately 10-6 Torr) environment to avoid heat loss.
D-WAVE provides an example of a commercial package that requires cryogenic cooling, power and classical control [The DWAVE two system (www.dwavesys.com/d-wave-two-system) utilises a closed cycle dilution refrigerator, magnetic shielding, vacuum system and classical control in a size approximately the same as a TEU container].
