Hybrid cooling towers or wet-dry cooling towers are closed circuit cooling towers that can switch between wet or adiabatic and dry operation. This helps balance water and energy savings across a variety of weather conditions. Some hybrid cooling towers can switch between dry, wet, and adiabatic modes.
Wet cooling towers operate on the evaporative cooling principle, but are optimized to cool the water rather than the air. Cooling towers can often be found on large buildings or on industrial sites. They transfer heat to the environment from chillers, industrial processes, or the Rankine power cycle , for example.
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
One BTU is the energy required to raise one pound of water one degree Fahrenheit, but the many different types of BTU are based on different interpretations of this “definition”. In the United States the power of HVAC systems (the rate of cooling and dehumidifying or heating) is sometimes expressed in BTU/hour instead of watts.
This increase in the high end of the temperature range allows data center operators to use entirely passive dry coolers, or much more efficient evaporative or adiabatic cooling towers instead of chiller-based air cooling or water chillers. This increase in the temperature range also allows operators using single-phase immersion coolants to more ...
An investigation showed that all five individuals may have been exposed to water droplets from a cooling tower behind the RiverWalk Resort in the downtown area of Lincoln, N.H., that tested ...
THTR-300 was in full service for 423 days. On 10 October 1991 the 180-metre-high (590 ft) dry cooling tower, which at one time was the highest cooling tower in the world, was explosively dismantled and from 22 October 1993 to April 1995 the remaining fuel was unloaded and transported to the intermediate storage in Ahaus. The remaining facility ...
