广州中央空调常见的6大疑难问题

广州中央空调常见的6大疑难问题

一、中央空调机器露点温度正常或偏低,室内降温慢产生原因及解决方法

①送风量小于设计值,换气次数少,请检查风机型号是否符合设计要求,叶轮转向是否正确,皮带是否松弛,开大送风阀门,消除风量不足因素。

②有二次回风的系统,二次回风量过大,请调节,降低二次回风风量。

③中央空调系统房间多、风量分配不均,请调节,使各房间风量分配均匀。

二:中央空调系统实测风量大于设计风量产生原因及解决方法

①中央空调系统的实际阻力小于设计阻力,风机的风量因而增大,有条件时可以改变风机的转数。

②设计时选用风机容量偏大,请关小风量调节阀,降低风量

三:中央空调系统实测风量小于设计风量产生原因及解决方法

①中央空调系统的实际阻力大于设计阻力,风机风量减小,条件允许时,改进风管构件,减少系统阻力。

②中央空调系统有阻塞现象,请检查清理系统中可能的阻塞物。

③中央空调系统漏风,应堵漏。

④风机达不到设计能力或叶轮旋转方向不对,皮带打滑等,检查、排除影响风机出力的因素。

四:室内噪音大于设计要求产生原因;

①中央空调风机噪音高于额定值,请测定风机噪音,检查风机叶轮是否碰壳,轴承是否损坏,减震是否良好,对症处理。

中央空调风管及阀门、风口风速过大,产生气流噪声,请调节各种阀门、风口,降低过高风速。

③中央空调风管系统消声设备不完善,请增加消声弯头等设备。

五:中央空调系统总送风量与总进风量不符,差值较大产生原因及解决方法

中央空调风量测量方法与计算不正确,请复查测量与计算数据。

②中央空调系统漏风或气流短路,请检查堵漏,消除短路。

六:中央空调室内气流速度分布不均有死角产生原因及解决方法

①气流组织设计考虑不周,应根据实测气流分布图,调整送风口位置或增加送风口数量。

②送风口风量未调节均匀,不符合设计值,应调节各送风口风量使与设计要求相符
