Heat pump 410a pressures.
Hence, R454B is not a drop-in placement for R410A. Here are some of the reasons why this is the case: R410A operates at higher pressures than R454B. This makes the compressor and the condenser less able to work with a low pressure refrigerant; The components used to manufacture systems that use R410A are not suitable for flammable …
Step 1. The process involves heating R-410a at a constant pressure from an initial state (1) t... Four kg/s of R-410a at 20∘C and 400kPa is heated, while maintaining a constant pressure, to 80∘C. The heat is supplied by a heat pump that receives heat from the ambient air and work input, as shown in the following diagram.The condenser comes charged with 15 feet of 410A. My install has 40 feet of 3/8" and 7/8" line total --- leaving 25 feet needing additional refrigerant. (Goodman suggest adding .6 oz per foot of liquid line) but that seems to be high. At the present time I am setting at 308 (High Side and 143 Low Side with no charge added beyond the 15 foot ...Our Ebook, Paperback, Workbook, Quick Cards: https://www.acservicetech.com/the-book This video is on Normal Operating Pressures are for Freon R-22 and R-410A...Re: Heat pump overcharged in heating mode. .

The only difference is the necessity to use a recovery machine and cylinders approved for the higher pressures of R-410A. Charging Since R-410A has a slight (0.3 degree) fractionation, it, like all other 400 series refrigerants, must be charged in the liquid state.

Always wear protective equipment, i.e. safety glasses or goggles and gloves, when working with any refrigerant. When charging or checking charge, always check for clean coils, clean filter (s), and proper air flow. Indoor air flow should be 350 to 450 CFM per ton of cooling, based on the size of the outdoor unit.
This rule is totally a fluke and has no scientific basis other than it just generally tends to work out that way. On a properly functioning R-22 system running in heat mode in 40-degree weather, the suction pressure tends to be around 40 PSIG. This guideline obviously doesn't work on an R-410A system or any other refrigerant.
