制冷劑R22、R410A、R404A溫度壓力對(duì)照表先給大家普及一些簡(jiǎn)單的估算方法: 如下: 冷凝溫度=工況溫度(空氣溫度/水溫)+(8~18)℃ 蒸發(fā)溫度=工況溫度(空氣溫度/水溫)--(10~20)℃ 舉例: 如何判斷制冷系統(tǒng)是否缺少冷媒?
很多人都說看系統(tǒng)的運(yùn)行壓力,但是新手基本上不知道怎么看; 很簡(jiǎn)單,比如現(xiàn)在室外溫度大概35℃,房間設(shè)定溫度27℃;那么根據(jù)上面的經(jīng)驗(yàn),得出: 冷凝溫度=35+10=45℃; 蒸發(fā)溫度=27-20=7℃; 當(dāng)然這些是估值哦。 根據(jù)我們下面的列表,很快就可以得出壓縮機(jī)運(yùn)行的高低壓了; 比如是R22冷媒的; 那么高低壓就是:1.75Mpa左右; 低壓就是:0.6Mpa左右。 如果低壓低于這個(gè)值,那要考慮系統(tǒng)是否缺少冷媒了。 好了,下面我們把R22、R23、R404A以及R410A溫度壓力對(duì)照表附給大家, | R22 | | 壓力 | 壓力 | 壓力 | 飽和溫度 | | Kpa | (bar/公斤) | (PSI) | 攝氏度 | | 100 | 1 | 14.5 | -41.091 | | 150 | 1.5 | 21.75 | -32.077 | | 200 | 2 | 29 | -25.177 | | 250 | 2.5 | 36.25 | -19.508 | | 300 | 3 | 43.5 | -14.654 | | 350 | 3.5 | 50.75 | -10.384 | | 400 | 4 | 58 | -6.5559 | | 450 | 4.5 | 65.25 | -3.0754 | | 500 | 5 | 72.5 | 0.12398 | | 550 | 5.5 | 79.75 | 3.0907 | | 600 | 6 | 87 | 5.8611 | | 650 | 6.5 | 94.25 | 8.4635 | | 700 | 7 | 101.5 | 10.92 | | 750 | 7.5 | 108.75 | 13.249 | | 800 | 8 | 116 | 15.465 | | 850 | 8.5 | 123.25 | 17.58 | | 900 | 9 | 130.5 | 19.604 | | 950 | 9.5 | 137.75 | 21.547 | | 1000 | 10 | 145 | 23.415 | | 1050 | 10.5 | 152.25 | 25.216 | | 1100 | 11 | 159.5 | 26.953 | | 1150 | 11.5 | 166.75 | 28.634 | | 1200 | 12 | 174 | 30.261 | | 1250 | 12.5 | 181.25 | 31.839 | | 1300 | 13 | 188.5 | 33.371 | | 1350 | 13.5 | 195.75 | 34.86 | | 1400 | 14 | 203 | 36.308 | | 1450 | 14.5 | 210.25 | 37.719 | | 1500 | 15 | 217.5 | 39.095 | | 1550 | 15.5 | 224.75 | 40.437 | | 1600 | 16 | 232 | 41.748 | | 1650 | 16.5 | 239.25 | 43.029 | | 1700 | 17 | 246.5 | 44.281 | | 1750 | 17.5 | 253.75 | 45.506 | | 1800 | 18 | 261 | 46.706 | | 1850 | 18.5 | 268.25 | 47.882 | | 1900 | 19 | 275.5 | 49.034 | | 1950 | 19.5 | 282.75 | 50.164 | | 2000 | 20 | 290 | 51.273 | | 2050 | 20.5 | 297.25 | 52.361 | | 2100 | 21 | 304.5 | 53.43 | | 2150 | 21.5 | 311.75 | 54.48 | | 2200 | 22 | 319 | 55.512 | | 2250 | 22.5 | 326.25 | 56.527 | | 2300 | 23 | 333.5 | 57.526 | | 2350 | 23.5 | 340.75 | 58.508 | | 2400 | 24 | 348 | 59.475 | | 2450 | 24.5 | 355.25 | 60.427 | | 2500 | 25 | 362.5 | 61.364 | | 2550 | 25.5 | 369.75 | 62.288 | | 2600 | 26 | 377 | 63.198 | | 2650 | 26.5 | 384.25 | 64.095 | | 2700 | 27 | 391.5 | 64.98 | | 2750 | 27.5 | 398.75 | 65.852 | | 2800 | 28 | 406 | 66.712 | | 2850 | 28.5 | 413.25 | 67.561 | | 2900 | 29 | 420.5 | 68.399 | | 2950 | 29.5 | 427.75 | 69.226 | | 3000 | 30 | 435 | 70.042 |
