When you have an R-410a heat pump I understand that in AC mode the indoor coil is the evaporator and that the smaller copper line is liquidhigh pressure and the larger line is vapor. Likewise people ask what are normal operating pressures for 410a. However this rule of thumb obviously does not. When charging an R-410A system you must charge from the refrigerant cylinder in the liquid form pull the liquid from the canister in the upside-down position and charge into the low side of the system. In heating mode however I have a small Evap means Cond in heating mode plus having to maintain low rate flow rate for noise level benefit. This will vary depending on OA.
Replaced accumulator and after recharging normally in cooling mode trips out in heat mode.

We couldnt actually convert a 22 system to 410A that simplybut you could have a 22 system and 410A system side by side operating under the same indoor and outdoor conditions and see about the same operating temperatures. Target superheat can. On a R-22 unit the suction pressure should be close to the OA. Another common rule of thumb is suction pressure will be close to the outdoor temperature in an R-22 system this is totally a fluke and has no scientific basis other than it just generally tends to work out that way. This video is a quick overview of how to check a heat pump in heating mode when it is below 65 degrees outside.

Heat Pump Pressure Superheat and Subcooling in HEAT - YouTube. Hi guys Ive got a reverse cycle ac running with R410a. For example to produce an evaporating temperature of 40 degrees F and a condensing temperature of 115 degrees the suction and head pressures would be 83 psia and 257 psia in an R-22 system while they would be 133 and 406 psia respectively in an R-410A system. In this clip I discuss my measurements while testing a 13 SEER American Standard in heat mode. Manifold sets should be 800 psig high side and 250 psig low side with 550 psig low side restart.
