問(wen)題說明(ming)：暖(nuan)通人(ren)員反(fan)映新風(feng)機初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)容(rong)易積塵，清洗(xi)太頻繁，初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)使(shi)用(yong)壽命太短。 問(wen)題分析：因為(wei)空(kong)(kong)調(diao)機組(zu)內增(zeng)加一層(ceng)過(guo)(guo)(guo)濾(lv)(lv)材(cai)質(zhi)的話(hua)，空(kong)(kong)調(diao)機組(zu)內 就會增(zeng)加一定(ding)(ding)阻力，導致機外余(yu)壓太小，對(dui)空(kong)(kong)調(diao)送風(feng)量有一定(ding)(ding)影(ying)響(xiang)。為(wei)避免對(dui)機外余(yu)壓有太大(da)影(ying)響(xiang)，選用(yong)過(guo)(guo)(guo)濾(lv)(lv)材(cai)質(zhi)過(guo)(guo)(guo)濾(lv)(lv)等級必須低于G4（初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)過(guo)(guo)(guo)濾(lv)(lv)等級）。 解(jie)決方案(an)：方案(an)1.在初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)前加一塊過(guo)(guo)(guo)濾(lv)(lv)棉(mian)，四角固定(ding)(ding)在初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)上(shang)。由于負壓，過(guo)(guo)(guo)濾(lv)(lv)棉(mian)會自然(ran)吸(xi)附到初(chu)(chu)(chu)效過(guo)(guo)(guo)濾(lv)(lv)器(qi)(qi)上(shang)，然(ran)后定(ding)(ding)期(qi)清洗(xi)過(guo)(guo)(guo)濾(lv)(lv)棉(mian)，從而減少初(chu)(chu)(chu)效清洗(xi)次數。 加上(shang)過(guo)(guo)(guo)濾(lv)(lv)棉(mian)后，需跟(gen)進調(diao)查此方案(an)對(dui)空(kong)(kong)調(diao)送風(feng)量是否有影(ying)響(xiang)和過(guo)(guo)(guo)濾(lv)(lv)的效果。
