For example, for the refrigerant R-134a, we would look up “R-134a PT Chart”. For the EPA exam, we need to know how to reference PT charts to: Find a saturation pressure given a temperature, or. Find a temperature given a saturation pressure. For refrigerant blends, we will see two pressures in their PT charts: Vapor Pressure, and.To calculate the superheat, subtract the saturation temperature from the measured refrigerant temperature: Superheat = 45°C – 10°C = 35°C. In this example, the superheat value is 35°C, indicating that the refrigerant is 35 degrees above its saturation temperature at the given pressure.SECTION 1.

The evaporator saturation temperature on the chart, reads 45 degrees …Refrigeration Product Bulletin R-448A APPLICATIONS: • Low Temperature Refrigeration • Medium Temperature Refrigeration PERFORMANCE: In R-22 Applications • Higher System Pressures • Lower Discharge Temperature • Existing TXV is suitable (some adjustment will be required) • Change lubricant to POE per manufacturer’s instructions In R-404A (or …

But when mixing an alternative refrigerant with R-22, there’s no pressure-temperature chart you can refer to. This means that you can’t optimize the system charge, which can lead to overheating and reduced system efficiency and lifetime. A loss of efficiency will occur. There may be an unpredictable and extreme change in efficiency as …A Cost-Effective R-22 Retrofit Refrigerant for AC and Refrigeration. Freon™ MO59 (R-417A) refrigerant is a hydrofluorocarbon (HFC) retrofit alternative for R-22 in direct expansion (DX) stationary air conditioning (AC) and medium-temperature commercial refrigeration systems. Because Freon™ MO59 is compatible with mineral (MO), alkylbenzene ... Features and Benefits. Freon™ NU-22B™ has an ASHRAE A1 classification and is non-ozone depleting and nonflammable. It is well-suited for AC applications because it closely mimics the operating characteristics of R-22 and works over the same operating pressures as R-22. ….
