Benefits of technology

The patent improves the efficiency of cooling systems by using energy from the incoming water to create a recirculating loop that increases the amount of water applied to the top of the system. This increases the effectiveness of the system and ensures better cooling performance.

Problems solved by technology

Such can result in substantial waste of cooling water.
This waste can significantly increase the cost of operating the system and also place a significant burden on water supplies, particularly in areas where fresh water is scarce.

Embodiment Construction

[0020]Several factors can influence the selection of the cooling fluid flow rate applied to the top surface of the evaporative pad in an evaporative cooling system. Preferably, sufficient cooling fluid is applied to the media so that at no location within the media does all of the cooling fluid evaporate before it can reach the bottom of the media. As the cooling fluid evaporates, the mineral content is concentrated in the remaining cooling fluid. Sufficient excess flow must be applied to ensure that the mineral content in no region becomes high enough that scale is deposited or precipitates out on the surface of the media. Scale deposits can eventually foul the surface and prevent sufficient or even air flow through the media.

[0021]Guidelines have been published to help designers choose a cooling fluid flow that will provide reliable performance. Examples include Munters Bulletin EB-IDI-0405, Munters Bulletin EB-WTM-0408, and Munters Bulletin EB-IDI-0712, which provide extensive de...

Abstract

An evaporative cooling system includes a heat exchange medium for receiving cooling fluid to cool supply air flowing past the heat exchange medium, a cooling fluid source for supplying fresh cooling fluid, a supply line communicating with the cooling fluid source for supplying the cooling fluid to the heat exchange medium, a return reservoir for collecting the cooling fluid supplied to the heat exchange medium, and a pump provided in the supply line for recirculating the cooling fluid collected in the reservoir into the supply line so as to provide recirculated cooling fluid along with fresh cooling fluid to the heat exchange medium. The pump can be in the form of an eductor.

Description

REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 242,569, filed Oct. 16, 2015.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is directed to improvements in evaporative cooling systems, and particularly to direct evaporative cooling systems. Evaporative cooling systems can be considered conditioning systems that utilize thermodynamic laws to cool a fluid. In evaporative cooling systems, a change of a fluid from a liquid phase to a vapor phase can result in a reduction in temperature due to the heat of vaporization involved in the phase change.[0004]2. Related Background Art[0005]Evaporative coolers typically include a contact pad or media made of structured corrugated fill composed of cellulose, glass fiber, or other media. This fill is used to act as an extended surface for the contact of cooling fluid with the air that passes through the media. Examples of this product go b...
