小型恒溫恒濕機日常維護與濾網更換周期建議
2025-12-13

小型恒溫恒濕機廣泛應用于實驗室樣品保存、醫藥存儲、電子元器件測試、文物養護等對環境溫濕度敏感的場景。其穩定運行不僅依賴精密的制冷/加濕系統,更離不開科學的日常維護。忽視保養,輕則導致控溫控濕精度下降,重則引發設備故障甚至樣品損毀。其中,濾網...

    干球溫度用普通溫度計測得的濕空氣的正常溫度。用符號t表示。單位:℃(攝氏度)。濕球溫度溫度計水銀球包裹有含水棉芯,并有一定流速的空氣吹過棉芯時,該溫度計所指示的溫度。用符號ts表示。單位:℃(攝氏度)。露點溫度空氣濕度達到飽和時的溫度,換言之空氣中的水蒸氣變為露珠時候的溫度叫露點溫度。一般凝結水或露水現象可以用露點溫度形成來解釋。用符號tl表示。單位:℃(攝氏度)。含濕量(含水量)在濕空氣中,與1kg干空氣同時并存的水蒸汽量稱為含濕量。用符號d表示。單位:g/kg(克/千克)...

    一、螺桿式冷水機組:螺桿式冷水機組是以各種形式的螺桿壓縮機為主機的冷水機組。它是由螺桿式制冷壓縮機、冷凝器、蒸發器、熱力膨脹閥、油分離器以及自控元件和儀表等組成的組裝式制冷裝置。目前,螺桿式冷水機組在我國制冷空調領域內得到越來越廣泛的應用,其典型制冷量范圍為700~1000kW。優點:1、結構簡單,運動部件少,易損件少,壽命長。2、圓周運動平穩,低負荷運轉時無“喘振”現象。3、壓縮比可高,EER值高。4、可在10%~100%范圍內無級調節,部分負荷時效率高,節電顯著。5、對濕...

    雖然制冷劑的溫度與壓力表達的物理意義不同,但類似R22的單組分制冷劑或共沸混合制冷劑在兩相區的溫度、壓力變化趨勢是始終嚴格一一對應的。為敘述方便,本文經常交替使用溫度與壓力來描述制冷劑的狀態。冷凝溫度與蒸發溫度雖在很大程度上受制于各自所處的環境,但二者變化趨勢仍密切相關。4.1冷凝溫度過低的原因與影響4.1.1冷凝溫度過低的原因冷凝溫度的決定因素是冷凝器的換熱能力與壓縮機排氣量的對比。在一個相對穩定的平衡狀態下,冷凝溫度保持相對穩定。當環境溫度降低或冷凝器風量增大或肋片淋雨(...

    a)存油彎的設置目的當系統的配管存在較大的落差時,為了防止冷凍機油無法有效回到壓縮機,影響壓縮機的使用壽命,因此在豎直管路上必須設置存油彎。當主機高于末端(蒸發器)時,就是主機在上,內機在下,蒸發器到主吸汽管之間有一段上升立管,因為冷凍油在蒸發器中不會蒸發汽化故積存在底部,當蒸發器底部積存冷凍油較多時就會堵塞吸汽管。如果蒸發器底部設置了回油彎后,油積存在這個彎頭里面的存量不會太多,只要該彎頭即將被堵塞,兩端的壓差足以將彎頭內有限的冷凍油“泵”出來,直至頂端的水平吸汽管,然后順...

    空調即空氣調節器(AirConditioner)。是指用人工手段,對建筑或構筑物內環境空氣的溫度、濕度、流速等參數進行調節和控制的設備。在人們的傳統觀念中,空調就是對空氣的溫度進行調節,簡言之,就是夏季制冷,冬季制熱。其實在空氣的指標中,除了溫度,濕度也是一項很重要的指標。傳統的濕度控制主要是集中在在一些特殊工業領域,比如制藥廠、卷煙廠、造船廠等,這些領域因為產品上或者制造工藝上的需求,需要對空氣濕度控制,使其控制在一定的范圍內。在民用領域,隨著社會的發展和進步,人們對隨著生...
