• Cooling towers have been proven effective in
  cooling down the water used and in rejecting heat
  produced in the industrial processes. However,
  the climate conditions can somehow affect the
  performance of cooling towers due mainly to the
  fact that they make use of the surrounding air as
  well as water supply to do their job. Today we
  are going to talk about how you can choose the
  right cooling tower system for areas with
  tropical climates. 
• The latent heat of evaporation is the primary
  source of energy utilized by industrial water
  cooling towers to deliver their effect. The
  extent of the cooling towers performance relies
  on water flow rate, water inlet and outlet
  temperature, and ambient wet bulb temperature.

• Before we dig further on the discussion, let us
  first define the kinds of temperature that
  directly and indirectly affects the function of
  cooling towers that are offered by different
  cooling tower suppliers.
• Dry Bulb Temperature - This is the temperature of
  moisture-free air. This is measured by a
  thermometer that is exposed in the air but
  protected from extraneous radiation and
  moisture.
• Wet Bulb Temperature - This is simply the
  opposite of Dry Bulb Temperature. This is the
  measure of the temperature of the moisture in the
  air. The thermometer that measures this has a
  bulb that is wrapped in a wet muslin cloth.

• Cooling towers are used by both small and large
  industries in countries all over the world. And
  they have been proven to help cool down the water
  and to reject heat produced in industrial
  processes. However, the climate conditions in
  various places can somehow affect the performance
  of cooling towers due mainly to the fact that
  they make use of the surrounding air as well as
  water supply to do their job.
• In tropical climates, the air is usually hot and
  humid. Because of this condition, cooling towers
  will have to exert a lot more effort in lowering
  the temperature of the air that it releases. This
  will result in an increase in water consumption
  and fan power.

So how does one decide what kind of cooling tower
to use in a tropical climate? Here are a few
guidelines. 

• Obviously, in a warm environment, a high-capacity
  cooling tower will be needed since there is a
  large amount of hot air that needs to be
  eliminated and converted to cooled air,
  therefore, more energy is consumed and more power
  is exerted.

Tower Cell Capacity
In such conditions, you will need to consider the
tower cell capacity. Multiple towers are
assembled together to increase their capacity.
Each tower is referred to as cell. The more
cooling towers in a group, the higher the
capacity.

Protection from sunlight

• The circulating water in the tower must not be
  exposed to direct sunlight to avoid microbial
  growth, which will then lead to algae formation
  that can damage the internal cooling tower parts.
  Crossflow-type cooling towers are automatically
  eliminated from the list because its design
  exposes the water to sunlight. Counterflow-type
  towers are the best choice since it has a
  protective casing unit for the water fill.

 Options depending on Air Movement

1. Natural Draft Cooling Towers. This kind of tower
   depends mainly on the natural air movement that
   flows through the tower to cool the water. In
   tropical climates, the air is typically warm and
   denser, which means it will easily circulate in
   and out of the tower, while the cooled air
   remains within the tower, and the air cycle
   continues.
2. Mechanical Draft Cooling Towers. This kind of
   tower creates its own air using engine-powered
   fan turbines to circulate air through the tower.
   However, it uses more power than natural draft
   towers.

Certifications
The performance of cooling towers is tested and
analyzed by the Cooling Technology Institute, a
world-renowned organization that verifies cooling
towers. This is to ensure that your cooling tower
is not altered to run at temperatures but have
extremely low efficiency when it comes to output.
It is important that as much as possible your
machine is CTI-certified. 
12
Material
In generally hot weather, the material used in
the construction of the cooling towers must be
able to withstand hot temperature, humidity, and
occasional rainfall. It must be durable and
resistant to drastic changes in air temperature
and possible natural disasters such as
thunderstorms, typhoons, and earthquakes.

• There have been several studies that analyzed the
  function of cooling towers in particular
  climates. Researchers from the Kuwait Institute
  of Scientific Research investigated the
  performance of a cooling tower in their country
  during the summer season when the temperature is
  extremely hot. They were able to figure out the
  relationship between airflow, electrical, and
  water consumption. According to Al-Bassam and
  company, airflow may be of significant
  contribution to cooling efficiency but also
  results in a higher electrical and water
  consumption.

• Tropical climate areas have high temperatures as
  a common characteristic but differ in terms of
  airflow, amongst many other factors. In choosing
  a cooling tower, one must have a thorough
  knowledge of the factors mentioned above and be
  able to decide on the most appropriate kind of
  cooling tower to use. A lack of frequent air
  movement means you will have to have a fan to
  produce the air you will need to circulate
  through the tower. Warmer air means higher water
  and electricity consumption for cooling,
  therefore you must ensure constant water supply
  and a strong electrical source.
