Everything went fine, until we went to balance out the system. The liquid pressure held at 165 no matter what we did, and the vapor pressure kept dropping down to 0. We tried adding freon, and tried taking out freon, but nothing made a difference.

If you are checking the charge then you need to check it by Sub-cooling (TXV) or Super heat (Piston). If you are doing it any other way you are just guessing. The are to many variables to say what should the reading be with an outside temp of 80. John Wayne once said "Life is tough and it is even tougher if you are stupid".

Posted by u/1alreadyr3ddit - 1 vote and 12 commentsR422D, also known as Freon MO29, is an R22 retrofit refrigerant comprised of R125 (65.1%), R134a (31.5%), and R600a (3.4%). It has a low boiling point of -44.7°C (-48.5°F) at 1 atmospheric pressure. That's why is used in low-temp applications such as air conditioners and cars. Here is what you can use this R422D pressure temperature chart for:See this chart and go to the 70F line. That line says that at 135 psia (121 psig) 75 lbs of liquid volume will convert to .4027 lbs (6.4 oz) of vapor at the same volume. So even if a 30 lbs cylinder was capable of holding 75 lbs of liquid, the vapor in that cylinder would only be 6.4 ounces, and that is at 121 psig.catching debris. we want a TXV to operate and equilibrium true or false. true. where do we look for a TXV to determine if used superheat or subcooling.

The heat pump will need to be recharged to restore the proper amount of refrigerant necessary for optimal performance. Only a certified HVAC technician should charge a heat pump or HVAC system. The tech will use one of two methods: superheat or subcooling. In most cases, subcooling is the preferred method, but the solution will depend on the ...

November 2, 2003. Several major manufacturers are producing comfort air conditioning equipment using refrigerant 410A. The trend towards the use of R-410A continues to grow and there is a demand for technicians who are comfortable working with this higher-pressure replacement for refrigerant 22. Due to the differences between R-22 and the newer ...T/P chart says pressure is say R22 is 168 @ 90 degrees. How can the OP even have numbers as low as was reported? I would think the unit would have to be nearly empty of charge to have numbers this low.... as I understand it (studying for my 608 T2 exam, BTW ), if I have even a few ounces of R22 in a container at 90F, the pressure should be 168 ...Usually with our R290 refrigerant, charging can be done by bringing the low side pressure up to a point of about 10 pounds below the outside air temperature. At 80 Degrees F. bring the pressure up to approximately 70 lbs. This works quite well up to about 85 degrees. Above that, we prefer the pressure to be 15 lbs below the outside temperature.- Goodman runs 45degrees F on low pressure side and 115degrees F on high pressure side. - 2 ton York runs 40degrees F on low pressure side and 110degrees F on high …65 psi R22 saturation temp is 37.5.

Connect R22 manifold gauge middle hose onto R22 refrigerant container. Flip R22 container upright and open the valve. Watch left and right gauges to see when pressure equalizes. Left-hand gauge should read below 60psi. Open left-hand gauge handle briefly to drop pressure. Allow system to run for 3-5 minutes.1. Even though this is not the cause of high suction, Clean The Evaporator, because it needs to be clean. If it's dirty, it causes LOW suction pressure, and causes inexperienced techs to overcharge a system. 2.

The ambient is 72°.Instagram:https://instagram. moriah plath net worthholyland halal meat grocerycarbs tootsie pophmong bobtail This would typically cause a low suction pressure, and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units.R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil. 4300 sheridan streetchrome browser themes What should R-22 low side pressure be? R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level. On the low-side R22 pressure at 85 degrees displays 60 psi, whereas on the high-side R22 pressure at 85 degrees shows 250 psi. ... 80° 45-50 psi: 175-220 psi: 75° 40-45 psi: 150-175 psi: 70° ... fights and knockouts Superheat Charging. To charge a system using superheat, you will need to monitor the actual temperature of the low-pressure suction line, the saturation temperature of the low side suction gauge, and the indoor and outdoor temperatures entering the unit(s).. Most, if not all, manufacturers have a charging chart available with their respective units. With the information you have gathered on ...The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.The needle valve may also get stuck partially open from grit or a sludging condition in the oil. This will cause high pressure to go directly into the compressor's crankcase causing high low-side pressures and low high-side pressures. The oil return line on an oil separator should be just above the ambient (surrounding) temperature.
