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，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物，但其吸水性極弱。</p><p style="text-indent:25px">液氨制冷劑透明無色，氨蒸氣無色，有強烈的刺激臭味。氨對人體有較大的毒性，當(dāng)氨液飛濺到皮膚上時會引起凍著。當(dāng)空氣中氨蒸氣的容積達到0.5-0.6%時可引起。故機房內(nèi)空氣中氨的濃度不得超過0.02mg/L。氨在常溫下不易燃燒，加熱至350℃時，分解為氮和氫氣，氫氣與空氣中的氧氣混合后會發(fā)生。與空氣混合的體積分?jǐn)?shù)在11%-14%時即可燃燒。在16%-25%時遇明火可能。在0.5%-0.6%時，人在其中停留半小時就會中毒。氨極溶于水，0℃時每升水能溶解130升氨氣。一般規(guī)定液氨中含水量低于0.2%。幾種制冷劑在空調(diào)中變得很普遍。</p><div
