Will R407c Work In A R410a Condenser? - HVAC-Talk
2018年8月9日 · The compressor pumps a fixed volumetric capacity and depending on the refrigerant that equates to a different btu output. Since the same volume pumped of 407c versus 410A is 35% less BTU the 410A condenser coils will be 35% oversized and therefore 35% more efficient so the head pressure will be slightly closer to ambient than a normally sized ...
I mixed refrigerants. R22 and 407C. And ran the system for a day.
2021年2月10日 · I put R22 in a 407c condensing unit. It was to replace some loss, and wasn't a large percentage, but maybe 10%. It ran for nearly 24 hours before I discovered the mistake. It cooled well enough. There was no excessive current draw. There was high head pressure. I would like to replace the refrigerant and have everything be just fine. What are ...
R407C in a R410A compressor - HVAC-Talk
2023年3月5日 · We are a local manufacturer of air cooled chillers. in our units we use R407C as refrigerant so our condensers max allowable pressure is 32bar (464.121 psi). But for this unit and the compressor model in copeland ZP (due to limited equipment on the market).
R407c and mineral oil - HVAC-Talk
2019年5月22日 · When the refrigerant is recovered and turned in, it has no acceptable identity, and it must be destroyed, at an additional cost. The best practice is to fully recover the R22, and charge with the appropriate refrigerant, which I listed, above.
Mixing 407C and R22 - HVAC-Talk
2016年5月22日 · to have a mixture of R22,R407C and R422D. Some of the counter guys at the supply houses are telling people its ok to mix them. I even heard one "tech" saying R407C cools better if you charge it in vapor. I have given up trying to explain why you should not mix refrigerants. It's sad.

Converting trane condensing unit fromm R22 to R407C - HVAC-Talk
2019年4月17日 · Whenever I have the opportunity to change an R22 compressor, I almost always convert the system to 407C (since all new R22 compressors seem to come with POE oil). I don't give the customer options on refrigerant - it's whatever I decide. If it's a refrigeration unit that I know can't tolerate even a small capacity drop, it's getting R22.
407c in a 410a unit - HVAC-Talk
2013年5月14日 · 410 systems use LESS refrigerant volume than 22 systems... and 407C is a 'close' replacement for mid and high temp applications of 22. If both of these are true... then this system (assuming it has the proper TXV/piston), will loose even more capacity than changing a dry unit from 22.
R-407C QUESTION - HVAC-Talk
2009年5月12日 · of the refrigerant that remains in the unit will change. The refrigerant remaining in the unit will be more concentrated in the high boiling component (HFC-134a) and less concentrated in the lower boiling components (HFC-32 and HFC-125). The effect of this composition shift on the performance of Suva® 407C is summarized in Table 4.
