How do you charge 410a.

The correct answer is 100 lbs. The point the EPA is trying to make here is that even after all the liquid refrigerant has been removed from a very large chiller, there is still a lot of refrigerant left in the chiller. For example at 85°F, the density of the R-11 vapor is 0.357 pounds per cubic foot.The R-410A has about 40 percent less heat-carrying capacity than the R-22. This causes the reduction of the replacement between the two different compressors. If an R-22 compressor has R-410A refrigerant put into the system, the motors will overload and burn out. The overloading can also cause the motor to start tripping the breaker, shutting ...Well, you can't charge to the high side. It should be obvious that the output of the compressor is going to be a higher pressure than the R-410a in the bottle at ambient temp. I have never done R-410a yet but as I understand it you charge liquid to the low side but *slowly* as to allow it to vaporize on the way in so it doesn't slug the compressor.Amazon is going to start charging delivery fees for Fresh grocery orders that are under $150, the company said in an email to Prime members.
