410a pressures on a 65 degree day
There is a solder that is rated for 410a pressures. It's called StayBrite 8. I've been using it for 20+ years on 410a systems. It does have its limits. I don't use it on compressor changeouts. But if done correctly, it works just fine. At my company the install crews use it on all changeouts. Our failure rate is less than .03%.Quick Example: Let’s say that we have a 3-ton 16 SEER AC are using R-410A refrigerant and want to calculate R-410A superheat. With low side blue gauge on the suction line service port, we measured 130 psi pressure that correlates (according to R-410A PT chart) to about 45°F. The clamp-on thermometer shows that the saturated refrigerant ...65. 137.3 135.5. 18.3. 115. 291.8 289.6. 46.1. -34. 8.0. 7.4. -36.7. 16. 51.5. 50.2. -8.9. 66. 139.7 137.8. 18.9. 116. 295.8 293.6. 46.7. -33. 8.6. 7.9. -36.1.

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. The sub-cool should be 11 deg. F +/- 1.5 deg. F.On a 100-degree day, the ideal pressures for R-410A refrigerant in an air conditioning system should typically be around 250-280 psi on the high side and 90-100 …The operating pressure of 410a on a 65 degree day is 185.7 psig. How to Calculate Superheat and Subcooling of 410a Systems Superheat and subcooling are two important parameters that indicate the efficiency and performance of 410a systems.
Your inability to operate the equipment at 40° screwed your client over. #3 the reason you can’t find anything on operating R-410A below 65° is there is no such rule. It makes no difference what type of refrigerant you have. It’s all about the equipment that it’s in.I am charging my heat pump it is an r410a and its about 90 degrees outside i have gotten the low side up from about 100psi to 130 and the high side from around 300psi to 340-50 is this about right what should my pressures be. The 410a part of the gauge is reading 44 low and 106 for high.If the pressure you are getting is down 10-15%, you probably need more refrigerant. Consult your user's manual to be sure or call Gree Electric Appliances, Inc. of Zhuhai. Second, you are looking at a heat pump. Verify the system is in cooling mode. IRstuff (Aerospace) 6 Jul 17 18:16.Originally Posted by Andhen. 30 because 30 degrees subcooling. A saturated head pressure 30°F above outdoor temp, doesn't get you 30°F of subcool. While 8 and 10 SEER A/Cs did often have to run 30° saturation over outdoor temp, you still only had 8 to 12° of subcool. Charge by subcool, or by superheat.
We can use the saturation pressure-temperature relationship for R-410A, which can be found in refrigerant property tables or online resources. Step 3/10 3. According to the saturation pressure-temperature relationship for R-410A, the initial pressure at 60°C is approximately 1960 kPa.

It's not. That's why we can have 5 heating degree days in one day and well more than 365 degree days in a year. Atlanta, Georgia has about 3000 heating degree days each year (65° F base temperature). It's not a unit of time.(R-508B) is a better replacement than Freon™ 410A. Properties Freon™ 410A is safe to use when proper storage and handling practices are followed.
