空调无热风故障可能的原因有2个方面:一是加热器芯堵塞,也就是热源失效;二是温度调节风门(或称为混合风门)动作不正常,导致鼓风机吹出的风没有通过加热器。但由于加热器芯和温度调节风门都设置在风道深处,到底是哪一种原因导致没有热风,难于直接观察、判断。使用风速计全面检测温度和风速的变化,可 Air-conditioning without hot air failure may be due to two aspects: First, the heater core plug, that is, heat failure; second is the thermostat throttle (also known as hybrid throttle) does not operate properly, causing the blower blower did not wind through the heater. However, due to the heater core and the temperature control damper are located in the duct depth, in the end is what kind of reasons lead to no hot air, it is difficult to directly observe and judge. Anemometer with a full detection of changes in temperature and wind speed can be
