The most common form of the water cooler is
wall mounted and connected to the building's water supply for a
continuous supply of water and electricity to run a refrigeration unit
to cool the incoming water, and to the building's waste disposal system
to dispose of unused water. Some versions are freestanding floor models,
which are becoming more popular in countries where it is not common to
drink water straight from the tap.
Traditional water fountains
In the standard wall-mounted cooler, also commonly referred
to as a water fountain or drinking fountain, a small tank in the machine
holds chilled water so the user does not have to wait for chilled water.
Water is delivered by turning or pressing a button on a spring-loaded
valve located on the top of the unit, that turns off the water when
released. Some devices also offer a large button on the front or side.
Water is delivered in a stream that arches up allowing the user to drink
directly from the top of the stream of water. These devices usually
dispense water directly from the municipal water supply, without
treatment or filtering |
