26 mar 2024 · In this post, I’ll go through the basics of a PH diagram and how to read it. From there, we’ll discuss each of the points in the PH diagram and see how they relate to the actual operation of air conditioners. Then, I’ll show you some of the things you can derive from the PH diagram.
9 paź 2002 · The compressor should then be refilled with normal lubricant. In order to prevent high acid levels from recurring, compressor operators should obtain a sample of the lubricant at least every 4,000 hours. Firms like Air Engineering and others will perform free laboratory analysis.
25 lis 2010 · pH values of acids like sulfuric, acetic and more..
Regardless of composition, HFC (R410a) and HCFC (R22) systems still run the risk of developing inorganic acids that can burn out the compressor. This can occur when contaminants and impurities (those not moisture, air, or excessive heat) enter the refrigerant system.
30 wrz 2020 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale runs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. Here is a ...
26 kwi 2014 · After mixing, the concentration of total formic acid and total acetic acid drop by a factor of 2 (mutual dilution). Formic acid is the stronger acid, and would have a pH of 3.06 at this concentration in the absence of acetic acid (less acidic than pH = 2.9 because of dilution).
