Air washer as a means of air conditioning.

Author(s) : HALASZ B.

Summary

Air washer is mostly used for the purpose of humidifying the air or just washing it (as a wet filter). In both these cases, water temperature is not controlled. Air tends to approach the saturated state at the inlet air wet bulb temperature. By controlling the water temperature and its flow rate, a limited control of air outlet condition can be achieved. Using the warm or cold inlet water can cause air to approach the saturation state at some other temperature, higher or lower than the inlet air wet bulb temperature. With sufficiently low water temperature air can even be dehumidified! The heat and mass transfer process in an air washer is basically the same as the one in a water-cooling tower, only the purpose is different - it is processing the flow of air here. The overall rating procedure obtained by the use of the nondimensional mathematical model is an algebraic routine which can be used either to calculate air outlet condition (if the water-air interface area is known), or the required water-air interface area for the desired air outlet condition.
