Artis – Aquarium Problem #SWI2002
The Artis Zoo has a problem in its Aquarium and in the adjacent Zoological Museum.
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.
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.
