Abstract

Heat generation is a very conspicuous phenomenon in large scale bioreactors and could in principle quite easily be measured by the temp. increase of the cooling water. Taking yeast cultures growing on a mixed oxido-reductive metab. for various reasons as an example, this paper demonstrates how heat dissipation measurements may be used in combination with other convenient online measurements order to obtain a quant. estn. of the nature of the on-going metab. and of the current overall stoichiometry. The application of such measurements to controlling fed-batch cultures is also discussed. [on SciFinder (R)]

Heat pipe

A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid, releasing the latent heat. The liquid then returns to the hot interface through capillary action, centrifugal force, or gravity and the cycle repeats.

Cooling tower

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators.

Water cooling

Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs and other components.
