Hybrid cooling plants may use a number of different technologies to provide cooling. These technologies include electric chillers, absorption chillers, engine-drive and/or dual-drive chillers, thermal storage systems and the use of a water-side economizer cycle. Most of these seek to pro-... 

LeLann et al. [6] discuss tendency modeling (using approximate stoichiometric and kinetic models for a reaction) and the use of model predictive control (linear and nonlinear) in batch reactor operation. Studies of a hybrid heating-cooling system on a 16-L pilot plant are presented. 

Freeze dryer with cooling system that allows plate temperatures of -55°C, e.g. Beta 2-16 (Martin Christ GmbH), equipped with cooling-trap and hybrid-pump (see Note 1). 

It seems that the SOFC-GT hybrid system should not be equipped with advanced cooling systems for the turbine. 950°C, the adopted highest temperature at the inlet to the turbine (TIT), is admissible for the blade material in the near term. 

An interesting and novel use of a soHd desiccant, the reduction of cold condensate corrosion in automotive exhaust systems, illustrates a hybrid closed—open system. Internal corrosion occurs in mufflers when the water vapor in the exhaust condenses after the engine is turned off and the muffler cools. Carbon dioxide dissolves in the condensate to form an acidic soup. In an essentially closed static drying step, an acid- and heat-resistant desiccant located in the muffler adsorbs water vapor from the exhaust gas as it cools to prevent formation of corrosive acidic condensate. When the engine is restarted, the system becomes open, and the desiccant is regenerated by the hot exhaust gas to be ready for the next cooldown step (19).

Amplification is achieved by repeated cycles (20 to 50) of heating (for strand separation) and cooling (for specific hybridization). Amplicons result upon ligation of adjacent probes. A commercialized automated system achieves detection...
