摘要
溶液调温调湿技术已广泛运用在建筑室内热湿环境的控制中。对四川绵阳某高校教学楼溶液调温调湿机组空气预处理器进行优化设计,即采用自编UDF程序,数值计算空气预处理设备除湿量及除湿效率与肋片参数的变化规律。当提高空气处理器的进水温度,优化肋片其他设计参数:肋片高度不宜超过19mm;厚度在0.10mm-0.25mm,间距在2.2mm-2.4mm;气流速度在1.7m/s-1.9m/s之间时,能满足除湿要求。同时采用高温冷水的空气预处理器比低温水时的效率更高,故采用高温冷源进行冷却减湿更为节能。
Solutiontemperature and humidityadjusting technology has been widely used in the construction to controlindoor thermal environment. Optimaldesignisdone for airpreprocessorin solutiontemperature and humidity regulatorat ateaching building of university in Mianyang, Sichuan province, namely by editing the UDF program, numerical calculating the capacity and efficiencyof air pretreatment equipment and finding thetransformlaw ofparameterabout fins. When raising water temperature of theairpreprocessor, andoptimizing the other designparameters of the fins：heightof fins no more than 19ram; thicknessfrom 0.10mm to 0.10mm, the spacingbetween 2.2mm to 2.4turn; air velocity in the 1.7m/s to 1.9m/s, can satisfy the requirement of dehumidification. At the same time, using the higher temperature cold water air preprocessor, the efficiency of nenrgy is higher than using the lower one. So, the higher temperature cold source adopted for cooling dehumidification is more energy-saving.
