Hello, I have a Rheem (2015) heat pump 2ton 410A, on cooling mode the system runs great; suction and liquid pressure are ok 185/360, super heat 10 F, with 90F outdoor temperature, now the winter is coming and the system on heating mode the gages read high pressure on both ...The discharge pressure is the pressure on the high side of the system, where the refrigerant is condensing. For a standard heat pump using the popular refrigerant R-410a, the suction pressure should be between 35 and 45 PSI (pounds per square inch) when running in heating mode. The discharge pressure should be between 300 and 450 PSI.Do you want to learn how to charge your mini split with 410a refrigerant? Watch this video and follow the instructions to get the job done. You will also find a link to buy the refrigerant online ...The amount of sub cooling can be determined by referencing the bubble temperature column. In order to determine the amount of superheat, refer to the column denoted "dew temperature.". R-452A saturated pressures are marginally lower than refrigerant R-404A; R-448A/R-449A pressures are slightly lower than R-404A. 6.The only way to ensure you got the right charge in the system is by weight. By reclaiming the charge and weighing the correct charge in. Further more, R410a is a blend of two refrigerants and if you had a significant leak then it is likely that the mixture of the remaining gas is no longer R410a, therefore if you had a leak the best practise is to recharge with virgin refrigerant.

Temperature and pressure chart for refrigerants R22, R410A, R12, R134A, R401A, R409A, R502, R404A, R507A, R408A and R402A.

Since R410A refrigerant is charged under higher pressure, charging an R22 system with it will increase the force within the coolant lines. The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either. This will contaminate the system, and the R22 will ...

If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building.Low-pressure switches on Carrier equipment using R-410A are usually set to open at about 50 psi and close at about 100 psi. Note: Heat pumps operating in the heating mode also may have a vapor switch that cycles the outdoor fan when the pressure is about 400 psi, and resets when the pressure drops to about 310 psi.This is entirely dependant on the running conditions of whatever plant you are working on at the time of measurement. if you have a chiller on r22 for example running with a suction of 100 psig and del. of 250 psig with water at +18 deg c, it will differ to an identical chiller with water at +8 deg c, or -8 deg c. pressures and temps. are very relative to each other and a good understanding ...On the other hand, R-410A can handle more heat allowing the compressor to run cooler. The compressors used in new AC units are built to withstand greater pressure that is caused by R-410A refrigerant. Using this refrigerant in an AC that is designed for R22 can put too much pressure on the systems and that can lead to premature wear and tear.Check the current low side pressure. A properly charged R410A mini split typically operates at about 110-140 psi in cooling mode and 250-400 psi in heat mode. ... In my past projects, we charge over thousands of mini splits based on the low side pressure and running amp. By doing so, we don't need to calculate the refrigerant pipe length and ...

The primary differences between the R22 and R410A air conditioning refrigerants are: R-22 is a single chemical compound, "Chlorodifluoromethane", a leak can be "topped off" without negative effect, the leak should be repaired but a "top off" is allowed on residential equipment. The refrigerant can be charged in either liquid or ...If your gauge doesn't show the different refrigerants you can download a pressure/temp chart off internet. Just record your high side pressure, and match it to 410A on the chart and thats your saturation temp. Okay you will find the required amount of subcooling on your maufacturing plate of unit or in users manual.

An R-22 Replacement for New ACs and Heat Pumps. Freon™ 410A (R-410A) refrigerant offers higher cooling capacity and significantly higher pressure than R-22 for use in systems specifically designed for R-410A. This hydrofluorocarbon (HFC) refrigerant is compatible with polyolefin (POE) oils and replaces R-22 in positive displacement air ...For air conditioning system, R22 pressure in discharge is250psi and suction in67psi. But for R410A pressure will be more higher that R22. So what pressure is normal for air-conditioning systems. Besides that normal R22 compressor can replace with R410A. by Mohammed Awais haji Latif.Below we list a dozen causes of high head pressure in an air conditioner or heat pump compressor motor.

However, our code (B52) sets the minimum design pressure for R410A to 236 psig for the low side, and 444 psig for the high side. (design can be higher, but not lower.) Your test at 450 psi is probably just fine, but 500 shouldn't hurt it.We would like to show you a description here but the site won't allow us.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 thought that R-410a is supposed to run at much higher pressures than R-22. R-410a saturation point at 80 psig is 21F -- which is below freezing! Which would mean that ice would form on the suction line if running at that low a pressure. Why do you think it's a bad compressor? It's an A/C / Heatpump unit. 2.5 tons Goodman unit. Scroll compressor.Table 1 compares pressure drops in temperatures and pressures for several common refrigerants. 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, resultsR-404A began seeing usage in 1996 after the phase out of CFC R-502 due to it's Ozone Depletion Potential. R-404A is a ternary refrigerant blend consisting of the HFC R-125 (forty-four percent), HFC R-143a (fifty-two percent), and HFC R-134a (four percent). R-404A is used across a variety of low and medium temperature applications including ...
