  • Publication number: 20120318009
    Abstract: A cooling tower includes an evaporator vessel, a gas delivery tube partially disposed within the evaporator vessel and a liquid inlet that provides liquid to the evaporator vessel. A weir is disposed within the evaporator vessel adjacent the gas delivery tube to form a first liquid circulation path between a first weir end and a wall of the evaporator vessel and a second fluid circulation path between a second weir end and another wall of the evaporator vessel. During operation, gas introduced through the tube mixes with the liquid and the combined gas and liquid flow at a high rate with a high degree of turbulence along the first and second circulation paths defined around the weir, thereby promoting vigorous mixing and intimate contact between the gas and the liquid. This turbulent flow leads to a more efficient and complete heat and mass transfer between the gas and the liquid.

  • Publication number: 20120210739
    Abstract: A screen of evaporative cooling media (“screen cooler”) is provided that may be adapted to partially surround the exterior compressor unit of an air conditioner. In some embodiments, the screen cooler may screen the AC unit from the sun and exposure to other forces or events that could potentially harm the AC unit. In some embodiments, the screen cooler is adapted to receive an input of a liquid, such as, for example, water and periodically emit the liquid onto the evaporative cooling media to keep the media moist and cool the air being pulled through the condensing coil and entering the compressor. By cooling the air prior to the air entering the compressor, the efficiency of the AC unit may thereby be increased.

  • Publication number: 20110225997
    Abstract: A data center cooling system is provided to maintain data center temperatures without introducing detrimental conditions into the data center. The computer data center cooling system has a cooling tower that controllably provides cooling water at a temperature in a particular range. The cooling water is then pumped through a series of filtration, treatment, monitoring and separation subsystems to reliably clean the cooling water of particles and treat the cooling water to reduce the harmful effects of corrosion and scaling. Further control subsystems utilize PID loop controllers to maintain the temperature to the air-handler unit cooling coils to within one (1) degree Fahrenheit of a set point that is determined by the computer data center air conditions. The cooling system utilizes either a primary loop or a combination of primary/secondary loops to achieve the highest system efficiency.
