href="http:....../....../www.gzshunjing.com....../" target="_blank"><span style="color:#009900;">冷庫<....../span><....../a><....../strong>運行時要注意的問題:   (1)冷庫運行中在保證冷庫溫度的前提下,盡可能采用較高的蒸發溫度。據文獻介紹,當蒸發溫度由-5℃降至-30℃時,在同樣制冷量下,能耗會增大1倍以上。也有資料指出,制冷裝置的蒸發溫度每升高1℃,節能2%~3%。可見蒸發溫度的變化對制冷裝置的能耗影響很大,因此應盡可能避免蒸發溫度過低。 <br ....../><....../p>  (2)合理確定冷凝溫度。由于冷凝溫度與冷凝壓力相對應,冷凝溫度升高,冷凝壓力也隨著升高,將使制冷壓縮機的排氣壓力升高,壓縮比增大。這就會使壓縮機的輸氣系數降低,功耗增大,經濟性下降。另一方面,壓縮比增大會使壓縮機排氣溫度升高,壓縮機的故障率增加,運行的安全可靠性降低。因此,應盡可能使制冷裝置在較低的冷凝溫度下運行。為了實現制冷裝置在較低的冷凝溫度下運行,安排制冷裝置在夜間運行是很重要的。因為夜間的環境濕球溫度較低,無論是各種水冷式或空氣冷卻式冷凝器,都會使冷凝溫度降低。這樣就會使制冷裝置的制冷量增加,能耗降低,達到節能效果。應該注意的是,在冷庫制冷工藝設計中要選擇合適的冷凝溫度,如果設計中選擇較低的冷凝溫度,可能會導致在實際運行中出現較高的冷凝溫度。因為按較低的冷凝溫度設計,由于冷凝負荷較小,選擇的冷凝器傳熱面積就較小。當運行中冷凝溫度高于設計值時,實際冷凝負荷增大,按較低的冷凝溫度選用的冷凝器將不能滿足需要,實際冷凝溫度將會升高,能耗增大,制冷裝置效率下降。 <br ....../><....../p>  制冷裝置安排在夜間運行,不僅使單位制冷量能耗降低,具有直接的節能效益,而且對地區電網具有“移峰填谷”的社會效益。目前各地都在推行峰谷電價差,冷庫在夜間運行可以享受到較低的電價。所以,對于冷藏庫的業主,實現制冷裝置夜間運行會獲得顯著的經濟效益。 <br ....../><....../p>  (3)合理選擇<a href="http:....../....../www.gzshunjing.com....../" target="_blank"><strong><span style="color:#009900;">冷藏庫<....../span><....../strong><....../a>的通風換氣時間。對于一些有通風換氣要求的冷藏庫,通風換氣引起的負荷是比較大的,因為冷藏庫內、外的溫濕度差很大,室內外熱濕交換對冷庫負荷的影響也大。如果安排在凌晨5:00~6:00,這時環境空氣的溫濕度都比較低,而且空氣比較清新,由通風換氣引起的熱濕負荷也就相對較小。一些高溫冷庫的運行經驗都證明了這一點。 <br ....../><....../p>  冷庫的節能包括各個環節,其操作管理也是關鍵之一。管理不善的冷藏庫,可能導致能耗比節能的冷藏制冷裝置高2~3倍。因此,為提高冷藏庫的業主多方面的綜合效益,冷藏庫業主也應該有充分的認識。          更多關于冷庫、醫藥冷庫、冷庫安裝工程、溫濕度監測系統、<a
