The Four Types of Refrigeration Systems You Need to Know
WebOct 6, 2008 · For example, the same size orifice that feeds 0.96 tons of capacity for R-22 will only feed 0.63 tons for HFC-404A, or 0.56 tons for HFC-422D on a 20° evaporator. As you can see, the capacity of the nozzle’s orifice is greatly affected when switching to or from R-22. Be very careful when working with those so-called drop-in refrigerants for ... WebApr 14, 2024 · The size of the capillary tube is fairly critical. Unlike orifices, such as expansion valve seats, capillary tubes depend on their length as well as their diameter to determine their total restriction.
