style="text-indent:25px">氨制冷裝置中不能使用銅及銅合金材料，并規(guī)定氨中含水量不應超過0.2%。氨的臨界溫度較高（tkr=132℃），汽化潛熱大，在大氣壓力下為1164KJ/Kg，標準工況下的單位容積制冷量也大，氨壓縮機尺寸可以較小。純氨對潤滑油無不良影響，但有水分時，會降低冷凍油的潤滑作用。氨在潤滑油中不易溶解，故要在裝置中設置油分離器，減少潤滑油進入冷凝器和蒸發(fā)器，防止熱交換表面被油污染后傳熱性能降低。純氨對鋼鐵無腐蝕作用，但當氨中含有水分時將腐蝕銅和銅合金（磷青銅除外），故在氨制冷系統(tǒng)中對管道及閥件均不采用銅和銅合金。上?；裟犴f爾R22多少錢新的解決方案是開發(fā)HFC族，來擔當制冷劑的主要角色。</p><div

style="text-indent:25px">R142b制冷劑，沸點較高-9.25℃.凝固點-130.8℃較大特點是在很高的冷凝溫度下，冷凝壓力并不高。如80℃時只有1.35Mpa，因此它適合在熱泵裝置和高環(huán)境溫度下使用。對大氣臭氧層有微弱的破壞作用，也將在2040年禁用。R134a，沸點-26.5℃，凝固點-101℃，無色，無味，不燃，不爆，但與礦物性潤滑油不相溶，必須采用聚脂類合成油（如聚烯烴乙二醇），與丁腈橡膠不相溶，故密封件須改為聚丁腈橡膠，吸水性較強，易與水反映生成酸，腐蝕管絡及壓縮機，對系統(tǒng)干燥度要求更高，系統(tǒng)中的干燥劑要換成XH-7或XH-9分子篩。壓縮機電機線圈絕緣材料必須加強絕緣等級，是一種不太成熟的制冷劑。</p><p style="text-indent:25px">C02應用研究的一個重要領域是熱泵熱水器（HPWH）。C02跨臨界循環(huán)中氣體冷卻器所具有的較高的排氣溫度，較大的溫度滑移和冷卻介質(zhì)的溫升過程相匹配，使其在熱泵循環(huán)方面具有獨特的優(yōu)勢。通過調(diào)整循環(huán)的排氣壓力，可使氣體冷卻器的排熱過程較好適應外部熱源的溫度和溫升需要。研究結(jié)果表明，當用環(huán)境空氣作熱源，0℃環(huán)境進水溫度8℃，熱水出水溫度為60℃時，該系統(tǒng)COP值高達4.3.一個更大優(yōu)點是毫無困難的產(chǎn)出90℃的熱水COP值仍較高。而普通的熱泵熱水器限制產(chǎn)水溫度在55℃以下。因而C02熱泵系統(tǒng)可較好的滿足采暖，空調(diào)和生活熱水的加熱要求。C02作為制冷工質(zhì)在熱泵中的應用將有效的解決空調(diào)冷熱源面臨的資源與環(huán)境壓力，應用前景良好。蒸汽噴射式制冷機用水作為制冷劑。</p><div

CFC族（氯氟碳）不可燃、無毒（和二氧化硫相比時）并且能效高。該機器于1931年開始商業(yè)生產(chǎn)并很快進入家用。威利斯.開利（Willis Carrier）開發(fā)了首先臺商用離心式制冷機，開創(chuàng)了制冷和空調(diào)的紀元。20世紀30年代，一系列鹵代烴制冷劑相繼出現(xiàn)，杜邦公司將其命名為氟利昂（Freon）。上?；裟犴f爾R22多少錢</p><p
