Introduction, Safety, General Retrofit Procedure.

You take the pressure temperature chart, otherwise known as. Medium temperature commercial and industrial direct expansion refrigeration and a/c. Yes, you got it right. For information on retrofitting, please refer to nri’s retrofit handbook at www.refrigerants.com/pdf/nri_retrofthndbk.pdf.

The Temperature Glide Runs About 13°F In The Evaporator.

Medium and low temperature commercial and industrial direct expansion refrigeration. Capacity loss will be greater in high ambient temperatures. Possible undersized txv or distributor nozzle based on pressure drop { up to 10% lower capacity at lower evaporator temperatures. Best match at medium temp evaporator / refrigeration.

Green (In Of Hg) = Vacuum Black (Psig) = Saturated Vapor (Calculate Superheat) Bold (Psig) = Saturated Liquid (Calculate Subcooling)

Web r422b pt chart. 186.3 f / 85.7 c. • slightly lower discharge temperature. 575.07 psia / 39.59 bara.

Possible Undersized Txv Based On Pressure Drop.

After visually inspecting a hvac system, locating the problem, and identifying the exact refrigerant used in that system, what do you do next? Best match at warmer evaporator temps / ac. • slightly lower discharge temperature. Possible undersized txv based on pressure drop.
