This low-maintenance, bench-mounting product contains a
heated water tank, a pump, a ducted fan and an
instrument panel. Each cooling column fits securely to the
heated water tank.
An electronic controller ensures a constant heated water
temperature throughout the tests. The centrifugal pump
delivers the heated water to a spray nozzle at the top of
the column. The water sprays into the column, passing
over ?packing? inside the column and returning to the
heated water tank. The fan directs air upwards through the
column in counter flow to the water, extracting the heat.
Electronic sensors measure the air and water flow,
humidity, pressures and temperatures at key points, shown
on clear, multiline displays. This gives all measurements
needed to understand the evaporative cooling tower
operation. Controls for the fan and water circuits allow the
students to adjust the flow rates for a full range of
experiments. A clear tube above the heated water tank
allows the user to measure the water lost to evaporation.
The Cooling Towers apparatus comes with one tower as
standard, for base experimentation. For comparison and
additional experiments, TecQuipment offer four optional
cooling columns. Two have different internal design or
?packing density? for a comparison of cooling performance.
The third column has the same dimensions as the first
three but has no packing. This column can show free-fall
cooling (a spray tower). It also allows the user to insert
other packing materials (not supplied). The fourth column
measures the effectiveness of evaporation cooling at three
intermediate stages during the water-to-air heat transfer.
Each column is of high-grade clear acrylic material. This
allows the user to see the complete process including the
water distribution and packing arrangement.
The equipment does not need a computer, as the displays
show all the measurements. However, TecQuipment has
included the powerful VDAS? inside the product. When
connected to a suitable computer (not provided), VDAS?
collects and displays accurate, real-time data quickly and
easily. It also displays live psychrometric charts.
