Abstract:
The flow of air in the fan cooling tower sprinkler channels in certain initial conditions may be characterized by the presence of a section of saturated humid air. In this case, the calculation of mass transfer according to the criterion equation of mass transfer, obtained from the analogy of the processes of heat and mass transfer, gives an overestimated result of the mass flow value. For the section of saturated air, the intensity of the mass transfer process is calculated using the function of changing the density of saturated steam from the air temperature. The works studying water cooling processes in the fan cooling tower sprinkler channels contain no assessment of the influence the saturated air presence has on the intensity of water cooling. The paper proposes a method for calculating the processes of heat and mass transfer in the cooling tower channels in the presence of a section of saturated air flow, taking into account the peculiarities of calculating mass transfer between water and saturated air. The values of the discrepancy between the final water temperature in calculations according to the proposed method and the method for unsaturated air are given. It is shown that the presence of a saturated air zone leads to an increase in the final temperature of the water compared to the calculations using formulas for unsaturated air. It is revealed that the discrepancy of water temperature calculated by different methods increases with the length of the channel, the value of the initial relative humidity of the air decreases with the growth in the initial air temperature. The offered methodology and obtained results can be used in the deve¬lopment of regime maps and at the design stage of fan cooling towers.

Abstract:
In the channels of mechanical-draft cooling tower sprinklers, a saturated air flow section may appear under certain initial conditions, the mass transfer intensity in which is limited by the steam content in the saturated air. For correctly calculating the heat and mass transfer processes in the cooling tower channel, it is necessary to have a method for determining the unsaturated air flow section length. Publications devoted to studying water cooling processes in the channels of mechanical-draft cooling tower sprinklers do not contain an assessment of the unsaturated air flow section length. A method for determining the unsaturated humid air flow section length in the mechanical-draft cooling tower sprinkler channels is proposed, which is based on the well-known criterion equations for calculating the heat transfer and mass transfer coefficients. The effect the initial air parameters have on the unsaturated air section length is studied, and graphic dependences of the unsaturated air section length are drawn up for each of the analyzed parameters. It is shown that the unsaturated humid air flow section length increases with increasing the initial air temperature. It is also found that the unsaturated air flow section length decreases with a growth in the relative air humidity. An increase in the air flow rate with a constant water flow rate leads to an increase in the unsaturated air flow section length. For the considered sprinkler channel, the saturated air region exists at an air temperature of 15°C and below, and for air temperatures above 25°C there is no saturated air flow section. It is shown that the conclusions drawn about the effect the initial air parameters have on the relative change in the unsaturated air flow section length are valid for channels of various shapes and geometric sizes. The proposed methodology and the results obtained can be used in designing mechanical-draft cooling towers and estimating their efficiency.
