Water is inexpensive, non-toxic, and available over most of the earth's surface.Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.
In arid and semi-arid climates, the scarcity of water makes water consumption a concern in cooling system design. From the installed water meters, 420938 L (111,200 gal) of water were consumed during 2002 for the two passive cooling towers at the Zion National Park visitors' center. [29]
ECCs (evaporative cooling chambers) and clay pot coolers provide the most benefits when they are used in low humidity climates (less than 40% relative humidity), the temperature is relatively high (maximum daily temperature higher than 25 °C), water is available to add to the device between one and three times per day, and the device can be ...
The cooling towers of a large chilled water system. As part of a chilled water system, the condenser water absorbs heat from the refrigerant in the condenser barrel of the water chiller and is then sent via return lines to a cooling tower, which is a heat exchange device used to transfer waste heat to the atmosphere.
Cornell University's Lake Source Cooling System uses Cayuga Lake as a heat sink to operate the central chilled water system for its campus and to also provide cooling to the Ithaca City School District. [3] The system has operated since the summer of 2000 and was built at a cost of $55–60 million. It cools a 14,500 ton (51 megawatt) load. The ...
In computing and electronics, liquid cooling involves the technology that uses a special water block to conduct heat away from the processor as well as the chipset. [1] This method can also be used in combination with other traditional cooling methods such as those that use air. The application to microelectronics is either indirect or direct.
This chilled water is then circulated within a district energy distribution system to supply buildings with cooling, then returned to the Energy Transfer Station. The potable water is supplied to the municipal drinking water system. Built at a cost of C$230m ($200m) over four years, the system is run by the Enwave Energy Corporation. [7]
Alternatively, a liquid-to-liquid or similar heat exchanger may be used instead. The high-temperature system transfers heat to a conventional condenser that carries the entire heat output of the system and may be passive, fan, or water-cooled. This is an auto-cascade process with two different refrigerants.
