盘管旁通系统是许多空调系统常用的温度调节方法,但由此会产生相对湿度偏离设计工况的问题。在某些情况下,相对湿度变化相当大,会造成空调区内人员的不舒适感。本文针对室内空气混及合空气两种旁通调节系统,采用 ASHRAE 的温湿度算法利用计算机迭代计算来确定室内相对湿度。在这一分析中,使用的参数有设计显热比、新风量和各种室外设计工况。固定冷盘管出口处的空气状态,按典型的方式改变室内显热冷负荷,研究由此引起的室内相对湿度的变化。
The coil bypass system is a common temperature regulation method for many air-conditioning systems, but this creates problems with relative humidity deviating from the design conditions. In some cases, the relative humidity changes considerably, which can cause discomfort to people in air-conditioned areas. This paper aims at indoor air mixing and air bypass control systems, using ASHRAE’s temperature and humidity algorithm to determine the indoor relative humidity using computer iterative calculations. In this analysis, the parameters used were design sensible heat ratio, fresh air volume and various outdoor design conditions. Fix the air condition at the outlet of the cold coil, change the indoor sensible heat and cooling load in a typical manner, and study the resulting changes in the relative humidity of the room.
