R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level. 8 psi g R22 is the short name for the halocarbon compound CHClF 2 (monochlorodifluoromethane), which is used as the refrigerant. Should I assume the problem is a weak compressor as the low side is within range and the high The liquid pressure should be 385-395 and the suction pressure should be about 138 but will probably be a few psi lower since it's so cool in the space.

Pressure: R32 operates at a lower pressure compared to R22 and R410A, which can result in smaller and lighter components for air conditioning systems. We measure that the temperature of the saturated refrigerant is 95°F (via pressure and referencing R-410A PT chart) 150 head pressure 60 suction pressure. NIST Standard Reference Database 23: Reference Fluid Thermodynamic and Transport Saturation Pressure-Temperature Data for R-22 (psig)* *Red Italics Indicate Inches of Mercury Below It was an r22 3ton that was around 20 yrs old. 5 0. 7 205. 05 1810 a1 • pressure€temp chart † temp. 2 156. This high pressure caused components such as compressors, evaporators, and condensers to fail and fail again and again. That means that the target superheat on a 100-day is between 6. This script determines the gas pressure based on temperature of R22 refrigerant. R-123 Critical Pressure. 1 110 112 77. Looked at my gage and its reading 100psi and it's 68 degrees out. This greatly increased airflow through the air handler on both sides and gave the owner a supply vent temperature of 60 +/- 1 degrees. 9 61. 4psi. 6 4. 2 163. 2 64 65.

You simply check the table above and see that the pressure of R134A on a 100-degree day is 124. And the fuel pressure regulator is arguably among its most important parts The pressure cooker is a must-have kitchen appliance these days. Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. 5 104. 8 387 373 Note! b) = boiling point and c) = critical point R417A is the zero ODP 1) replacement for R22 suitable for new equipment and as a drop-in replacement for existing systems. Look at the pressure chart or you gages and subtract the line temperature from the actual temp that will give you the subcool. 0 -17. 8 50 84. for the most part R22 runs pressures of 75-85 PSI suction and 210-225 liquid when the unit is running with proper charge on an average 80 degree day. You need to get a temperature/pressure chart, and then take the ambiet temp. At 74°F indoor WB temperature (on 100°F day), our target superheat is 21°F. 1 1810-15 13. Where I live, temperatures often exceed 100 degrees farenheight. your probaly overcharged. R22 PT Chart: Pressure Temperature Chart For -60°F To +155°F; R454B PT 100. 9 psi g 105° F 40. 7 60 61. Could be lower or higher, just depends on how the system was designed. 63° superheat says the evaporator is Does this unit have a SG and what did it show? You didn't state the other pressures and temperatures but the SG is a tool to use in determining system conditions. 04 0 0 0 0 0 * Please note that on small percentage of the recent split systems which are pressure rather than temperature driven, performance of Minus 60 versus the original refrigerant must be assessed on the case-by-case basis. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is R-22 Replacements Pressure-Temperature Guide Key: Green (in of Hg) = Vacuum Black (psig) = Saturated Vapor (calculate Superheat) Bold (psig) = Saturated Liquid (calculate Subcooling) Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees). 08 3. Example 8: What Are R422D Pressures On A 100-Degree Day?
