Experimental Research on Heat Resistances of Vertical Evaportive Condenser

Abstract:

Based on the experiment of vertical evaporative condenser in water vapor condensation, the influence between heat resistances and water spray density, air inlet velocity, spiral inserted tube, wavy tube was studied. The results show the heat resistance at the air-water interface predominates over all other heat resistance, air-water interface heat resistance is particularly declined up to 20.65% with spiral inserted tube, and water condensation heat resistance is particularly declined up to 35.85% with wavy tube.These conclusions are useful for the design, optimization and application of this type of evaporative condenser.
