Not without a proper conversion.
Yes, R404 is denser than air. R404 is a refrigerant gas that is typically used in cooling systems and it is heavier than air, so it can sink and accumulate in low-lying areas.
No. NEVER mix refrigerants or use any refrigerant other than what the system is intended to use.
NO
all refrigeration standing pressure in psi
No, you should not use R-134A in a compressor designed for R-401A. These two refrigerants have different chemical properties and operating pressures, which can lead to inefficiencies, potential damage to the compressor, and safety hazards. It’s essential to use the refrigerant specified by the manufacturer for optimal performance and reliability.
there is no set answer ,you have to ajust pressure using subcool and superheat. if these terms confuse you i recomend calling an hvac contractor
INSTEAD
No. You absolutely cannot mix any refrigerants. You should completely recover all the old refrigerant and charge the system, with the new refrigerant, using the superheat method.
you can use or , otherwise, or rather than.
what can i use instead of glyerin in making tootpaste
You Can Use Paper Bags Instead Of Plastic
We could use leather instead.
