直接蒸发式与串联式独立新风空调系统性能实验研究
|
摘要
通过建立空调系统测试实验台,就直接蒸发式与串联式独立新风空调系统进行性能研究。研究影响系统性能各因素,并分析两种空调系统在各因素下的运行性能,以及室内盘管保持干工况下运行的适用条件。得出当室内负荷显热比低于0.8,或者室外温度升高到35℃、相对湿度增大到65%的工况下,串联式系统比直接蒸发式系统更具结露的风险。且适当增加新风量有利于改善室内温湿度过高的现象,但新风量过大,容易造成室温偏高。
Trough the setup and testing of dedicated fresh air conditioning system,the performance of direct evaporation and series air conditioning system was analyzed by experiments.The operation characteristics of two systems were compared under different conditions,as well as indoor temperature and humidity changing.The suitable conditions for indoor coil to maintain dry conditions run was also evaluated.
