https://www.acprocold.com/faq/r-134a...ressure-chart/ 9) Until the "Ozone protecting" legislation of the early 90's, shops and individuals (like me ;-) charge systems by Pressure/Temp charts for R-12 (or R-22 on home systems). There is NO Reason an individual CANNOT do that to...
A rather simple or basic procedure for determining the current superheat of a charged system requires an ac gauge set, thermal probe and an R134a “PT” (pressures and temperatures chart). You measure the average low pressure on the low side of the system. You then measure the average tempe...

国内外很多机构都已开展了相应的研究工作,如S .G .Ki m [1]等对采用CO 2分别与R134a 和R290为制冷剂的自复叠制冷系统进行了理论与试验研究,其分析了CO 2的配比对于CO P 值的影响,但他主要获取-30℃以上的蒸发温度,所以其对于提高低温下自复叠系统CO P 意义不大。彭勃等对采用工质R744/R290 的自复叠制冷...
