Cooling Towers
John Herbert
Director
Air-conditioning system use cooling towers to reject heat energy
extracted from the building, and factories use cooling towers to cool
process machines, for example hydralic presses and injection
molding machines.
Water based cooling towers systems provide significant benefits over
air-cooled systems, including lower energy costs, smaller size, and
lower sound levels.
Cooling towers use less total energy than an air cooled systems,
and a well-maintained cooling tower enables the entire cooling
system to perform more reliably and ensures that users get the
most from their investment.
In 2000, 32% of the total electricity consumption in Hong Kong was used
to drive air-conditioning[1] converting to water based technology,
i.e. cooling towers offers superior energy advantages, reduces power
station air pollution and helps keep more of your hard earned money in
your pocket.
Hong Kong Cooling Tower Scheme
In June 2000 a co-operative effort between various government
departments introduced the fresh water energy conservation pilot
scheme. Under this scheme, commercial operations may choose to use
fresh water for evaporative cooling, typically employing cooling
towers for heat rejection.
Cooling Towers Cost Savings
Hong Kong air conditioning systems account for more than forty
percent (40%) of commercial building energy usage, and up to seventy
percent (70%) of the electrical usage. An in Hong Kong, electricity
accounts for nearly 70% of emissions in 2013 data released in June 2016
The total energy cost for water based cooling tower systems are
typically 13-17% lower than the dry type counterparts.
Furthermore, if we considering that the real cost of energy never
diminishes, charges have risen over the last ten years, the long term
outlook for water based cooling, cost savings accrue very quickly.
For example, an air conditioning system with a cooling capacity of
600Kw (approx. 170 tons), converting to water cooled would save about
HK$500,000 per year. And assuming a conservative lifespan, lets say
fifteen years, a cooling tower system would save approximately
HK$ 7.5 million.
In addition to the direct cost savings, there are indirect benefits
too, the reduced electrical consumption equates to lower environmental
emissions at the power station.
