You eliminated every other cause for a high low pressure (Air flow, refrigerant, compressor txv). I would try touching and observing the piping for any sudden change in temperature. Student here, so take this with a grain of salt. 2.

The port sizes for R410A and R22 TXV's are basically identical, so they would each have the same flow capacity with either refrigerant . The difference is a R410A TXV will work properly with R22 only if you change out the R401A powerhead to one for R22. It'll then actually control superheat. The Educational Forums.i just installed a new split unit r-410a a/c system. it is running at 285/120 psig. the high side seems way low, should be about 420. the correct orifice is installed. …

The refrigerant pressure inside the system is measured when the equipment is not running and has sat idle long enough for the pressures in the system to equalize. Then, using a gauge manifold we can determine the pressure ...

25 May 2017 ... In this HVAC Video, I go over how to Calculate a Refrigerant Charge on an Air Conditioning Condenser by Measuring Temperature and Pressure ...History of R-454B as a Refrigerant. R-454B was developed in the late 2010s by Chemours and was formulated to serve as a lower GWP (global warming potential) alternative to R-410A, the usage of which has dominated the commercial HVAC market since the phaseout of R-22. R-454B, marketed by Chemours under the trade name …Pressure Range Low side: 36 to 50 psi High side: 284 to 356 psi Indications Both pressures are TOO HIGH The low-side piping is not cold Causes Air in the system Remedy Evacuate the system Replenish the refrigerant Check the gauge readings If prolonged operation with air in the system, the liquid tank must be replaced.The R-410a is then run through an evaporator (heat exchanger) to cool down a cross-flow of warm air. The air is flowing at 0.121 kg/s and atmospheric pressure (100 kPa) and is cooled down from 300 K to 280 K at constant pressure. When the R-410a exits the evaporator, it is a vapor and has expanded to a pressure of 500 kPa (State 3).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.

When it comes to efficiency, both R410A and R32 are very efficient refrigerants. However, R32 is slightly more efficient than R410A. One important difference between these two refrigerants is their boiling point. The boiling point of R-410A is -51.5°C, while the boiling point of R-32 is only -26°C. This means that R-32 can cool air more ...

In order to effectively flush R22 lines for 410A, it is recommended to remove the existing oil from the system. This is because R22 uses mineral oil, whereas 410A uses synthetic oil. Failure to remove the mineral oil can cause compatibility issues and affect the system's performance. 3. Flushing R22 lines for 410A involves using a flushing ...

Still though... something doesn't sit well with me about all of it. I think I'm going to change the switch for good measure and reclaim/meter in the charge again. According to my PT chart, the static pressure of R410A at 65° is 185psi. I'm guessing that's not what you were asking about, but that's what it is.Heating mode: outside temp >65F: Run AUX only - lock out compressor (avoid high pressure) outside temp >10F and <65F: Run compressor and AUX as needed. outside temp <10F: Run AUX only - lock out compressor (avoid defrost cycling) Cooling mode: outside temp <60F: lock out compressor, run air handler fan only.Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.pressure of about 250 psi at an outdoor temperature of 95°F. With R-410A, the same unit will operate under the same conditions with a suction pressure of 118 psi and a discharge …Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions "indoors" does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.What is r410a's suction pressure? When operated at a 35 degC ambient temperature, the suction pressure of an Air-Conditioner with R410A refrigerants ranges from 115 to 125 Psig. At these operating conditions, the discharge pressure is around 400 Psig. R-410A operates at 50 to 70% higher pressures than the R-22. Related Articles:

Note that the refrigerants have different pressure drops for the same change in temperature. For example, many documents refer to acceptable pressure drop being 2°F (1.1°C) or about 3 PSI (20.7 kPa) for R-22. The same 3 PSI change in R-410A, results

NOTE: Care should be used in the standing pressure comparison.

Feb 4, 2015 · The high side guage was connected to the liquid line. Static, both guages are 160 psig. When the unit ran, BOTH guages dropped to about 130. The high side was perhaps 2-5 higher. The amp draw at the compressor was 8.6 RLA out of a 22.1 suggest maximum on the equipment sticker. R-410A systems operate at higher pressures than R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. Service equipment must be rated for R-410A.

Adjust sensors or set points to operate the compressor continuously while charging the system. Add refrigerant to allow the discharge pressure to rise to 325-420 psig.R-410A systems operate at approximately 60% higher pressures (1.6 times) than R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. Use appropriate care when using this refrigerant. Failure to exercise care may result in equipment damage or personal injury. • Only match this outdoor unit with a matched indoor use on R-410A refrigerant systems.

Jan 3, 2014 · 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.

Get it up to 200 and it would be grossly overcharged. It will be likely running in the 35 to 45f degree saturation (boiling point) range, 108 to 131 psi. The high side has an even greater range. The pressures will vary as the operating conditions like return air temperature, outdoor temperature change.

Now let's look at the pressures required to do the same cooling using R410a. The high-side pressure needed to compress R410a into a liquid at 90° is 274 psig. The low-side pressure required to cause R410a to evaporate at 50° is 142 psig. And since this is almost twice the pressure that the R22 liquid requires to evaporate, R22 clearly ...High Suction Pressure R-410a. i went to check an 3.5 ton a/c brand is a ICP (international comfort products) Model WAPL424A1, not cooling my pressures were low side 185 to 190 and high side was around 350 on a 107F hot day.
