Nu 22 Refrigerant Pt Chart

Pressure temperature chart.

Nu 22 refrigerant pt chart. The composition of freon mo99 and freon nu 22b refrigerant have been designed to provide performance comparable to r 22 in terms of both capacity and energy efficiency. Refrigerant pressure temperature chart use the open or close icons to see the descriptions below with the icons.

The pt chart for nu 22 and nu 22b suggests that the txv would need to have spring pressure increased when the conversion. Nu 22b is designed for use with mineral oil and does not require the use of poe oil.

Icor s nu 22b is an ozone safe replacement that closely ma. In the 1950 s the use of r 22 exploded and for nearly sixty years it was the refrigerant to be used in home office and commercial air conditioning. Freon nu 22b is compatible with all standard oils equipment components and materials used in r 22 systems. R 22 was invented by a partnership with general motors and dupont back in the 1930 s.

Always refer to the refrigerant manufactures written guidelines. Is nu 22 or nu 22b a drop in refrigerant. A no oil change r 22 ac replacement refrigerant. R 22 refrigerant is the major refrigerant or it was.

Weights of refrigerant in cu lines lbs 100 lineal feet. I don t know but i am convinced that great care should be taken to get before and after measurements particularly superheat. Is r 407c a better r 22 replacement than nu 22b. Is nu 22b an acceptable replacement.

As a result minimal system modifications are anticipated when retrofitting properly sized systems. I don t think so. Industries commercial businesses property owners and others looking for an r 22 replacement to maintain their air conditioning ac systems can turn to freon nu 22b refrigerant. Pressure values are displayed for r 22 r 410a r 407c r 134a and r 404a refrigerants.
