Refrigerant pressure readings R-22, R-410A, R-290, R-417A 1 Standing pressure – 150 PSI 2 Saction pressure – 60 TO 70 PSI 3 Discharge pressure – 250 TO 300. Freon gas standing and working pressure ( R32, R410A, R502,R407C, R134A etc )And, since compressor overheating problems are today's most serious compressor field problems, service technicians must carefully monitor compressor discharge line temperatures and keep them below 275° (275° + 75° = 350°). The main reasons for high compressor discharge temperatures are low suction pressures, high condensing pressures ...Currently working on a Bremar ice maker. Just did a compressor change and thought I weigh charged it perfectly. But it's not making good ice. I have only a suction port to read the pressures, and I'm getting 300kpa at the beginning of the 8.5 min cycle, and around 240kpa by the end. It runs for 8.5miutes then goes on defrost to drop the ice made.Sep 25, 2023 · Here are the steps to properly charge a 410a AC system: Turn on the air conditioner. Connect the gauges. Measure the system’s pressures and temperatures. Calculate the target subcooling and superheat. Add refrigerant. Monitor the subcooling and superheat. Disconnect the gauges.

Scroll down to download a PDF copy of the pressure enthalpy chart for both Metric and Imperial Units.The pressure of R-410A is so high that if your hand gets in the way of a leak, it could cut a finger off. This is a myth, as well as a physical impossibility. Devices such as insulin jet injectors require 7,000 to 10,000 psi pressures to puncture the skin and 16,000 to 25,000 psi pressure spikes are normally used.
Refrigerant regulations are changing quickly at the state and federal levels, in order to facilitate a smooth transition away from R-410A to lower-GWP refrigerants. Finding a replacement for R-410A has been challenging, but several alternatives have emerged as top contenders. One of those is the mildly flammable (A2L) refrigerant, R …It's a split system in a 2 br/2 bth condo in Palm Springs, CA. A/C seems to working fine. They did not replace the evap coils inside, nor the copper lines. The new compressor came uncharged and they installed R22 freon, (which they charged me $800 for.) I noticed the compressor documentation specifies use of R-410A refrigerant.TEMPERATURE - PRESSURE CHART FOR R-22, R-410A, R-407C, R-134A & R-404A REFRIGERANTS FYI #289 9/17/2009. updated 10/10/2012.

Nov 2003. Location. South Carolina. Posts. 1,167. Post Likes. 404A Walk-Cooler. You guys will have to excuse the ignorance of basically an HVAC guy who has been thrust into the position of doing a good bit of reefer work. I have a 404 walk in cooler where the temp is hovering slighlty above 50 degrees box temp.
Checked the voltage to the motor and it was running at 100%, once the room was cooled it dropped to about 60% and stayed there. 85* outside and set to 64* inside, so that seemed okay. at 100% the indoor unit was pulling in air at 70* and dropping it to 55*.Pressure/temperature relationship. I was discussing some pressures with another tech. He asked me about an r410a unit that the pressures were 125 psig= 43 degrees back pressure over 350psig =107 degrees condensing pressure he says oh that's all out of whack and 350 is to high because when I do my maintenances I usually see 150/275 300 max.Physical Properties Of R22. In parallel to using the R22 PT chart, professionals will usually need to know some of the following R22 physical properties: R22 liquid density at -69°C: 1.49 g/cm 3. R22 gas density at 15°C: 3.66 kg/m 3. Triple point temperature: -115.76K. Critical pressure: 49.36 bar. Heat capacity ratio at 86°F: 1.178253.So, to be clear, before we move on, it is 100% OK to add to an R410a charge without fear of any significant fractionation. If you want more information about fractionation, check out this article. R410a is a near-azeotropic blend of 50% R32 and 50% R125. While it has a tiny amount of temperature glide, you can still work with it like a zero ...So we replace the compressor (same model #), replace the liquid line filter dryer, and evacuate to 500 microns.

Jul 16, 2021 · This screenshot of the Ref Tools app shows the vapor line pressure of R410A at saturation at 39°F. Notice how the slider has been set to DEW point (inside the orange box). Before we even hook up our gauges/probes, we know the system operating pressures should be within +/- 10 PSI of: Liquid Pressure: 356.5 PSIG. Vapor Pressure: 116.1 PSIG Using the previous examples comparing the operating pressures of an R-22 system to an R-410A system, the. R-22 system would have a compression ratio of 3.02:1, while the R-410A system would have a compression ratio of 2.98:1. The actual efficiency gains from R-410A are due to its superior thermodynamic values over R-22.This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions. What are normal operating pressures for 410A mini split? The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. However, it should not fall below 100 psi or ...Yep, put in a R410A metering device. And convert back to R410A. There are still lots of people afraid of the higher pressures of R410A. So may have been done to keep pressures lower. others thing R410A compressors pump more refrigerant, to get the higher pressure, and think that used for R22 it will be more efficient.5.1.2 Heating Operation. Constant evaporating temperature (Te) control Basic target value: R22 = 115°F (46°C), R407C = 118°F (48°C), R410-A = 115°F (46°C) *Compensation is applied. Constant superheated degree (SH =Ts-Te) control Basic 9°F (5°C) compensation is applied.On to what’s changed. Ok, so obviously the refrigerant has changed but the big and noticeable difference here is the pressure change. 410A is anywhere from fifty to sixty percent higher pressure than R-22. So, while the basic design and operating procedures of 410A remain the same as R-22 extra caution should be paid to the pressure of 410A.It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
