地下工程调温除湿机的节能优化方案及性能模拟研究

摘要

根据显热、湿转换原理,对现有调温除湿机性能进行了分析,提出了节能优化方案.该方案在调温除湿机的蒸发器前增加了一个冷却盘管,使湿空气预冷后再沿接近饱和状态线除湿,能够达到节能的目的.通过对调温除湿机系统进行仿真模拟,得出系统模型中通过冷却盘管的冷水适用的温度范围为18~25℃,调温温度范围为15~37.5℃.%Based on the conversion principle of heat entranspy and moisture entranspy,the performance of current dehumidifier with temperature control was analyzed,energy saving optimization scheme was proposed.This scheme added a cooling coil before the evaporator in dehumidifier with temperature control.It is possible to precool moist air before dehumidifying along the line close to saturation and achieve the goal of energy saving.Through the simulation result of dehumidifier with temperature control system,we got a useful temperature range of cooling water in cooling coil is 18~25℃ and tempering temperature range is 15~37.5℃ in system model of dehumidifier with temperature control.
