style="text-indent:25px">R12為烷烴的鹵代物，學(xué)名二氟二氯甲烷，分子式為CF2Cl2。它是我國中小型制冷裝置中使用較為較廣的中壓中溫制冷劑。R12的標(biāo)準(zhǔn)蒸發(fā)溫度為－29.8℃，冷凝壓力一般為0.78～0.98MPa，凝固溫度為-155℃，單位容積標(biāo)準(zhǔn)制冷量約為288kcal/m3。R12是一種無色、透明、沒有氣味，幾乎無毒性、不燃燒、不爆炸，很安全的制冷劑。只有在空氣中容積濃度超過80%時才會使人窒息。但與明火接觸或溫度達(dá)400℃以上時，則分解出對人體有害的氣體。R12能與任意比例的潤滑油互溶且能溶解各種有機(jī)物，但其吸水性極弱。R404A是不破壞大氣臭氧層的環(huán)保制冷劑。蘇州干冰制冷劑多少錢</p><p

CFC族（氯氟碳）不可燃、無毒（和二氧化硫相比時）并且能效高。該機(jī)器于1931年開始商業(yè)生產(chǎn)并很快進(jìn)入家用。威利斯.開利（Willis
