Indoor return dry-bulb and wet-bulb temperatures. You will plug these into the chart or calculator, and you will get a target superheat, generally somewhere between 5 and 25 degrees. ( HERE is a video showing how to find target superheat.)
R22 has a very similar boiling point to R290 (-41.4°F to 44°F; that’s only a 2.6°F difference). At 100°F, however, the pressure of R22 is 195.9 psig and the pressure of R290 has a pressure of 174.3 psig (check the R290 PT chart below). This is a 20+ psig difference and you will easily tell if you have an R290 or R22 freon.We call this the pressure-temperature (P-T) relationship. This relationship will exist as long as you have at least a droplet of liquid in a closed system. However, the refrigerant must be at its saturation point. Saturation can be confusing, so this article will explain saturation and how a P-T chart fits into the concept.
Many service technicians often become confused when the liquid line becomes restricted in the refrigeration system. This is because the symptoms often look like an undercharge of refrigerant. This article covers a refrigeration system with a restricted liquid line after the receiver using R-134a as the refrigerant. The refrigeration system is a …The high side pressure, in contrast, refers to the refrigerant pressure in the discharge line. This is basically the pressure after the compressor. Even though the ideal pressure range for an R-401A air conditioner falls in the range of 110-140, its low side pressure should not be less than 100 psi, nor should it be more than 160 psi.How to Use a Two-Column Pressure-Temperature Chart Properties of the new zeotropic refrigerant blends are different than traditional refrigerants, it is useful to know how to read a two-column PT chart. Traditional PT charts list the saturated refrigerant pressure, in psig, with a column for temperature down the left side. Single-component refrigerants and …If, for example, the discharge temperature were 210° with a 150 PSI head pressure and a 10 PSI suction with a 50° outdoor temperature, this would show an extreme undercharge. You can still check the subcool and superheat in heat mode; the problem is that since there are rarely any set guidelines, it is difficult to tell when the charge is set ...DR-5 had slightly increased discharge temperature by 3 to 5°C (5.4 to 9°F). For R1234yf and DR-4, the compressor discharge temperatures were lower by about 11 to 30°C (20 to 55°F) and 5 to 9°C (9 to 16.2°F), respectively, in comparison to that of R410A.

In addition, the scroll compressor's suction and discharge openings are farther apart than those in a reciprocating compressor, ...One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.Ps SUCTION PRESSURE The pressure at the compressor inlet expressed as psia (or Bar-a).
