Reduce energy consumption, increase equipment life and cut maintenance downtime by consolidating heat transfer.
In a conventional closed-circuit evaporative cooling tower or evaporative condenser (figure 1), water is circulated from an integral basin to a spray system that evenly distributes water over the outside of a heat exchange coil. Excess or waste heat from the process fluid or refrigerant flowing inside the coil is transferred through the tube walls of the coil to the circulated water. Heat then is transferred from the water to air, which is simultaneously blown over the coil counter-current to the circulating water. The heated air ultimately is rejected into the atmosphere through an evaporative heat transfer process. The heated water is returned to the basin, where it is recirculated over the coil.
