12等，中文名稱二氟二氯甲烷，英文名稱Dichlorodifluoromethane，分子式CCl2F2。由于R-12屬于CFC類物質(zhì)（首先批受限的ODS物質(zhì)Class I Ozone-depleting

style="text-indent:25px">制冷劑飽和蒸氣的溫度與壓力呈對(duì)應(yīng)關(guān)系，若已知制冷劑的蒸發(fā)溫度即可查出相對(duì)應(yīng)的蒸發(fā)壓力。此壓力的表壓值由高、低壓壓力表顯示出來(lái)。因此，根據(jù)安裝在系統(tǒng)上壓力表的壓力值即可判斷制冷劑的充注量是否宜適。例如：空調(diào)器的蒸發(fā)溫度為7.2℃，冷凝溫度為54.5℃使用R22。查R22的飽和溫度與飽和壓力對(duì)應(yīng)表，以確定其蒸發(fā)壓力值和冷凝壓力值。查表可知：R22在7.2℃時(shí)相應(yīng)相對(duì)壓力值為0.53Mpa(5.3kg/cm2)和54.5℃時(shí)的相應(yīng)相對(duì)壓力值為2.11Mpa(21.1kg/cm2)，將此壓力換算為表壓值即可。用高、低壓壓力表或復(fù)合式壓力表測(cè)試充氟中的制冷系統(tǒng)，若高、低壓力表表壓值符合上述范圍即表明制冷劑的充注量合適;若高、低壓壓力均低則表明充入量不夠;若高、低壓壓力均高，則表明充入量過(guò)多。壓力測(cè)定法較為簡(jiǎn)便，在維修時(shí)經(jīng)常作用，但是缺點(diǎn)是比較粗，準(zhǔn)確度不高。制冷劑需較高的傳熱系數(shù)、較低的粘度及較小的密度。蘇州高效制冷劑價(jià)錢</p><p
