Bench Top Cooling Tower Standard instrumentation allows measurement of the air, circulating water mass flow rate and all end state temperatures using wet and dry bulb thermocouples. Bench Top Cooling Tower unit incorporates a process load, circulating pump, packed column, water distribution, volume control system and fan. Reproduces all the processes that are found in an industrial system serviced by a forced draught cooling tower. Evaporation rates under varying load and flow conditions can also be investigated.
External Capabilities:
Measurement of all end states and rates of flow of water, air and make-up.
Plotting of end states on a psychrometric chart and the application of the steady flow equation to draw up energy balances.
Observation of water flow pattern and distribution.
Investigation of performance at,
A range of process cooling loads.
A range of inlet temperatures.
The self-sufficient unit allows to perform experiments on water cooling by using Three interchangeable cooling towers having packings with different heat exchange surface.
