Perkins）在1834年建造了首臺實(shí)用機(jī)器。它用做制冷劑，是一種蒸氣壓縮系統(tǒng)。二氧化碳(CO2) 和氨(NH3)分別在1866年和1873年首先被用作制冷劑。其他化學(xué)制品包括化學(xué)氰（石油醚和石腦油）、二氧化硫(R-764)和甲醚，曾被作為蒸氣壓縮用制冷劑。其應(yīng)用限于工業(yè)過程。</p><p style="text-indent:25px">液氨制冷劑透明無色，氨蒸氣無色，有強(qiáng)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(shí)會引起凍著。當(dāng)空氣中氨蒸氣的容積達(dá)到0.5-0.6%時(shí)可引起。故機(jī)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(shí)，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(shí)即可燃燒。在16%-25%時(shí)遇明火可能。在0.5%-0.6%時(shí)，人在其中停留半小時(shí)就會中毒。氨極溶于水，0℃時(shí)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%。制冷劑在較高溫度下轉(zhuǎn)移給冷卻水或空氣。</p><div
