恒溫恒濕箱蒸發(fā)器運作原理

發(fā)布日期:2022-07-24 點擊率:78

    恒溫恒濕箱蒸發(fā)器運作原理看似簡單,卻是不可或缺的一部分,是保證試驗箱能夠制冷的重要環(huán)節(jié)。

    第一,是液態(tài)制冷劑流入蒸發(fā)器,分為上進下出和下進上出兩種方式。

    第二,是管外空氣的熱量傳遞給管內的制冷劑,以至于能使周圍的空氣因失去熱量而降低溫度,制冷劑又因為吸收熱量而蒸發(fā)。

    第三,是通過吸熱后蒸發(fā)器中產生了蒸汽,壓縮機將蒸汽抽走,保證液態(tài)制冷劑的低壓狀態(tài),以便能夠使液體制冷劑在較低溫度下實現(xiàn)蒸發(fā),同時也為吸收熱量的制冷劑提供足夠空間。
