江西省螺桿式冷水機(jī)供應(yīng)商產(chǎn)品簡介
螺桿式冷水機(jī)因?yàn)椴捎寐輻U式壓縮機(jī)而得此名。它的制冷功率比渦旋式冷水機(jī)的功率大,主要應(yīng)用于化工廠、油墨印刷廠、汽車制造廠或者*空調(diào)系統(tǒng)或其他大型工業(yè)制冷方面。
江西省螺桿式冷水機(jī)供應(yīng)商工作原理
螺桿式冷水機(jī)因其關(guān)鍵部件-壓縮機(jī)采用螺桿式故名螺桿式冷水機(jī),機(jī)組由由蒸發(fā)器出來的狀態(tài)為的氣體冷媒;經(jīng)壓縮機(jī)絕熱壓縮以后,變成高溫高壓狀態(tài)。被壓縮后的氣體冷媒,在冷凝器中,等壓冷卻冷凝,經(jīng)冷凝后變化成液態(tài)冷媒,再經(jīng)節(jié)流閥膨脹到低壓,變成氣液混合物。其中低溫低壓下的液態(tài)冷媒,在蒸發(fā)器中吸收被冷物質(zhì)的熱量,重新變成氣態(tài)冷媒。氣態(tài)冷媒經(jīng)管道重新進(jìn)入壓縮機(jī),開始新的循環(huán)。這就是冷凍循環(huán)的四個(gè)過程,也是螺桿式冷水機(jī)的主要工作原理。
