長沙高低溫交變恒溫恒濕試驗箱制冷系統
1.系統理念:此類實驗箱均采用業界的溫度平衡技術(制冷不加熱),通過能量調節技術在降溫及低溫平衡時不需要另外啟動加熱來平衡控溫。能量調節技術即PID控制調節制冷劑流量,通過調節控制單位時間內進入蒸發器制冷劑的質量,來達到精確控制制冷功率,從而精確控制試驗室的溫度。
2.相對以前“平衡控溫方式”即邊加熱邊制冷的方法,能耗非常大。而運用此技術可在zui大限度上降低客戶的運營成本和延長壓縮機的壽命,可在產品壽命周期內可為用戶節約一筆不小的電費開支(因客戶實際使用頻率高低而已)
3.制冷劑:采用環保制冷劑R404a。
4.制冷硬件:采用“泰康”全封閉壓縮機組成制冷循環系統。
5.制冷蒸發器:采用波紋翅片制冷蒸發器,位于試驗箱一端的風道夾層內,由鼓風電機強制通風,快速換熱。
