Understanding the pressure that your system is at as well as knowing what the saturation point is of R-134a will allow you to properly diagnose what is wrong with your system.
A Mass Flowrate Correlation for Refrigerants and Refrigerant …
WebR134a has been found to have a GWP of 1300 and in Europe, within a few years, automobile air conditioning systems will be barred from using R134a as a refrigerant. The new hot topic is a return to carbon dioxide (R744) as a refrigerant (refer for example to the website: R744.com). The previous two major problems of high pressure and high ... WebThis investigation examined mass flowrate of R12, R134a, R502, R22, R407C, and R410A through short tubes. Short tube length ranged from 9.5 mm to 25.4 mm, and sharp edged diameters ranged from 1.09 mm to 1.94 mm. The correlation covers both single-phase and two-phase entrance conditions under approximately choked flow. The literary context of psalm 137
