Performance Analysis of a Small-Sized Screw Cooling Tower

Abstract

Abstract In this Article describes analysis of efficiency, i.e. analysis of coefficient of thermal - and mass transfer, which carried out thanks to increase of time of phases interaction in developed cooling tower with a spiral air flow. There is given a description of the construction of effective the small-size cooling tower with the spiral type airflow. The main difference of the cooling tower of the existing constructions of that the sprinkler, made of layers of cylindrical polymer cellular pipes, laid on screw line, alignment to the current of the screw type airflow. The small-size cooling tower operates as following: the water, heated at technological process from the closed loop of system is brought to water distribution system. It is distributed evenly on all square of the sprinkler laid on the screw, in which take place a heat and mass transfer of the water and air spiral type flow, which is create by the fan. There is a swirling of the gas phase the tangential feed of the cooling air flow in the bottom of the cylindrical small-size cooling tower, and it can be described by two elements of speed: rotational and translational. Such action allows to intensify a heat and mass transfer processes.
