What is the working principle of an evaporative condenser?

The working principle of the evaporative condenser is to send the high temperature steam that needs to be condensed into the coil from the upper inlet of the heat exchange coil. The high temperature steam releases heat in the heat exchange coil and undergoes phase change and condenses into liquid after being cooled. The circulating spray water is used as the cooling medium outside the heat exchange coil, so that the water is evenly sprayed on the outer surface of the heat exchange coil to form a uniform and moderate water film. The water film absorbs the heat released by the hot steam in the coil and evaporates , And then take the water vapor out of the evaporative condenser by the fan to take away the heat in the coil. The evaporative condenser uses the latent heat of evaporation of spray water, uses ambient air as the medium, and uses the ambient wet bulb temperature as the temperature difference for heat exchange. It has low condensation temperature, large heat transfer temperature difference, sufficient heat exchange, low power consumption, stable performance, etc. advantage.
