板式蒸发式冷凝器传热传质的数值模拟
Numerical Simulation on Heat and Mass Transfer of Plate Evaporative Condenser
摘要
Abstract
Two-dimensional mathematical model of the heat and mass transfer process among refrigerant, cooling water and air in the plate evaporative condenser was established on the basis of energy and mass conservation. Distributions of cooling water temperature, air temperature and air humidity ratio are obtained. And then studies on influencing factors of plate evaporative condenser heat flux, i.e., air flow rate, cooling water spray density, air dry bulb temperature, wet bulb temperature and the condensing temperature were conducted. Simulation results were verified through experiments, and the error was less than 10%. The results showed that heat flux increased with increasing air flow rate, increasing condensing temperature and decreasing air wet bulb temperature, and is not relevant to air dry bulb temperature. With the increasing cooling water spray density, heat flux gradually increased and then kept constant. These conclusions are instructive for optimization design of plate evaporative condenser.关键词
