R22 suction and discharge pressure chart.
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.
slightly higher discharge pressure. As a result, minimal system modifications are anticipated when retrofitting R-22 systems to Freon™ 407C. Original equipment manufacturers should be contacted to determine if discharge pressure controls will need to be adjusted to compensate for the higher discharge pressure. Table 2• Recovery of R-448A requires a recovery cylinder with a service pressure of 300 psig minimum. General Considerations: R-22 Applications • TXVs. R-22 expansion valves will likely have the proper capacity range for R-448A. Some adjustment of superheat will be neces-sary after retrofit. • Performance. R-448A will provide higher capacity ...On the pressure-enthalpy diagram superheat is shown as horizontal movement along the suction pressure line passed the 100% vapor curve. The figure on the following page shows the difference between 0 °F and 15 °F superheat. Point B is the 100% vapor point at a constant evaporator/suction pressure of 36.8 psia and a temperature of 25 °F.16 September 2012. Updated: 20 July 2017.

Limit the pressure drop in the discharge line to 6 psid whenever possible to minimize the adverse effect on unit capacity and efficiency. While a pressure drop of as much as 10 psid is usually permissible, note that a 6-psid pressure drop reduces unit capacity by 0.9 percent and efficiency by 3 percent. To design the discharge line properly,Mar 20, 2019 · The higher the GWP the more harm the refrigerant does to the climate. R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United States as well. If, for example, the discharge temperature were 210˚ with a 150 psi head pressure, a 10 psi suction, and a 50˚ outdoor temperature, this would show an extreme undercharge. Subcool and superheat can still be checked in heat mode, the problem is since there are rarely any set guidelines, it is difficult to tell when the charge is set correctly ...The retro˚t procedure for replacing R22 with RS-44s is as follows: 1. If possible collect baseline data before conversion. Suction and discharge pressures can be converted to temperature using an R-22 pressure temperature conversion chart. Once the average evaporating and condensing temperaturesmo99 pressures. what kind of suction pressures are you guys getting with mo99 on resi splits (1.5-5 ton)? i usually try to go by the chart on the unit but the charts are for r22. will mo99 run at the same pressure as r22? i mean its the same unit. when i charge replacement dry units with mo99, it seems like the suction pressure never goes above ...
