風機(ji)盤管風量一(yi)定，供(gong)(gong)(gong)水(shui)(shui)(shui)溫度一(yi)定，供(gong)(gong)(gong)水(shui)(shui)(shui)量變(bian)(bian)化(hua)時，制(zhi)冷量隨供(gong)(gong)(gong)水(shui)(shui)(shui)量的(de)變(bian)(bian)化(hua)而變(bian)(bian)化(hua)，根(gen)據部分風機(ji)盤管產品性能統計，當供(gong)(gong)(gong)水(shui)(shui)(shui)溫度為7℃，供(gong)(gong)(gong)水(shui)(shui)(shui)量減(jian)少到80%時，制(zhi)冷量為原(yuan)來的(de)92%左(zuo)右，說明當供(gong)(gong)(gong)水(shui)(shui)(shui)量變(bian)(bian)化(hua)時對(dui)制(zhi)冷量的(de)影響較為緩慢。


 風機盤管供(gong)、回水(shui)溫(wen)差(cha)一定，供(gong)水(shui)溫(wen)度升(sheng)高時(shi)(shi)，制冷(leng)量隨著減少，據統計，供(gong)水(shui)溫(wen)度升(sheng)高1℃時(shi)(shi)，制冷(leng)量減少10%左右，供(gong)水(shui)溫(wen)度越高，減幅越大，除濕能力下(xia)降。

供水條件一定，風機盤(pan)管風量改變時(shi)，制冷量和空氣處理(li)焓(han)差(cha)隨著變化，一般(ban)是制冷量減少(shao)，焓(han)差(cha)增大(da)，單位制冷量風機耗電變化不大(da)。

風(feng)機盤(pan)管進、出水溫(wen)差增大時，水量減(jian)少，換熱(re)盤(pan)管的(de)傳熱(re)系數(shu)隨著(zhu)減(jian)小(xiao)。另外，傳熱(re)溫(wen)差也發(fa)生(sheng)了變化，因此，風(feng)機盤(pan)管的(de)制冷量隨供(gong)回水溫(wen)差的(de)增大而減(jian)少，據(ju)統計當供(gong)水溫(wen)度為7℃，供(gong)、回水溫(wen)差從5℃提高到7℃時，制冷量可減(jian)少17%左右。

熱(re)環境(jing)條(tiao)件是指物(wu)理(li)參數對人體的(de)(de)熱(re)舒適性所(suo)發生的(de)(de)綜合(he)作用。這些(xie)物(wu)理(li)參數中(zhong)主要包括(kuo)空(kong)(kong)(kong)(kong)氣干球溫度(du)(du)(du)、空(kong)(kong)(kong)(kong)氣的(de)(de)相對濕度(du)(du)(du)，空(kong)(kong)(kong)(kong)氣流(liu)動(dong)速度(du)(du)(du)、平均輻射溫度(du)(du)(du)、人體的(de)(de)代謝量(liang)及(ji)衣著等六項。其中(zhong)，空(kong)(kong)(kong)(kong)氣的(de)(de)溫度(du)(du)(du)及(ji)流(liu)動(dong)速度(du)(du)(du)是評價(jia)風機盤管(guan)所(suo)提供的(de)(de)熱(re)環境(jing)舒適條(tiao)件的(de)(de)重要參數。
