Ceramic Fill Cooling Tower Offers Environment friendly, Durable Air Conditioning At College

Architects and engineers working at Armstrong American State University in Savannah, Ga., have put in an aesthetically pleasing ceramic water-cooling tower for the school’s student Union and Memorial College Middle that they say will provide heating, ventilation and air conditioning for many years.

The fundamental know-how behind this system is fairly low tech: Water is sprayed over ceramic fill materials leading to evaporative cooling. The cooled water is circulated by way of a heat exchanger that is connected to a separate air circulation system. In the case of AASU’s four hundred-ton system, a single giant fan circulates water over a grid of 25,000 tiles.

The primary huge difference between the ceramic-tile fill system and a typical institutional HVAC PVC-fill system is the appearance of the tools, itself. As an alternative of the massive and unsightly steel and PVC box methods discovered on top or outside of big office buildings and hospitals, designers can create architectural towers that nicely mix into the lines of a building and landscaping. As obvious above, the AASU cooling tower turns the set of water streams into one thing that looks extra like a fountain.

One consideration is the time horizon of the building proprietor. Short term buyers may be averse to the extra capital cost (some estimates peg the preliminary price of a ceramic tower at 4-instances a daily air-cooled HVAC system). Alternatively, these in it for the long haul, such as a college or hospital, can justify the preliminary expense of the towers for a number of causes.

First, the ceramic programs are rugged and impervious to the elements and designed to final 30-40 years. This contrasts with typical air-cooled HVAC techniques that require common maintenance and nonetheless must be replaced every decade or so because the fill clogs, UV rays degrade the tubing and moisture corrodes the metal surfaces.

Gary Drummond of Tower Engineering Inc., the cooling tower manufacturer that assisted Rosser architects with the AASU project, says ceramic techniques maintain 100% thermal performance for life and are additionally immune to freeze-thaw cycles and are impervious to biological growth and chemical attack.

Drummond says he and others at the company have expertise constructing these towers since 1968. The technology actually started in 1947 and one of the current improvements is a change to a tile-grid system such because the one used in AASU as an alternative of getting the water move over brick-like items. “We call it excessive-performance ceramic fill because the tile system is rather more environment friendly because of increased wetted floor area and less static pressure requirement. We also can use TEI’s variable-velocity fan motor system to offer even more financial savings with less horsepower and less maintenance,he says.

Rosser’s Chuck Hanning, who has been concerned with the college undertaking for about two years, tells the AASU student newspaper that standard air-cooled chillers require 1.2 to 1.3 kilowatts of power per ton of cooling, in contrast with ceramic towers that only require 0.5 to 0.7 kilowatts per ton.

A ultimate plus for ceramic fill cooling towers is design freedom. Rosser and TEI tout that these methods easily may be designed around a variety of parameter moreover look, together with an means to withstand hurricanes and earthquakes.

Drummond says TEI guarantees the thermal efficiency of the company’s ceramic fill programs for 25 years. He additionally notes the tiles and blocks used in the company’s towers aren’t extraordinary in themselves. He says they’re just laborious-burned clay that can be readily supplied by global brick making amenities.

Have you learnt the place I can buy the ceramic fillings. As I want it for my mission. Thank you

This is a good design of an air conditioning system. It’s a really fascinating topic. Many of the bloggers will recognize of the positioning. I hope you proceed posting more topics. 🙂

I watched a video on Planet Green and it included a house cooled with an ancient ceramic tile system. There are similarities with your system. I’m involved on something on one of these cooling system.
