Artis Aquarium Problem
in Dutch
The Artis Zoo has a problem in its Aquarium and in the adjacent
Zoological Museum.
Situation
Part of the Aquarium is a corridor which contains so called mammoth
tanks which measure 5 by 2.5 by 20 meters and are filled with
water.
Because of the tropical fish inside, the water should have a temperature
of 24 degrees Celsius. As there is not much daylight, a dozen lamps have
been placed just above the aquarium to make sure the fish inside are visible.
However, these big lamps produce a lot of heat.
Problem
When in summer time the outside temperature reaches 25 degrees,
the temperature in the corridor containing the mammoth tanks
increases
up to 30 degrees.
The water itself becomes 27 degrees, which is too much for the fish
inside.
In the neighbourhood of the lamps, the temperature rises to 40
degrees. Just under the roof sometimes temperatures of 60
degrees have been measured.
The museum, adjacent to the aquarium, is suffering from the heat
as well:
a lot of objects (like stuffed animals) are no longer
allowed to be displayed.
There are some fans, but these can not do the job, especially not if doors
are opened to fight the heat.
Question
How can we change this situation with a minimum of cost and
inconvenience for the visitors, employees and fish?
