Refrigerants Pressure Enthalpy Charts. The pressure-enthalpy diagram (log P/h diagram) is a very useful tool for refrigerant technicians, engineers and researchers. Since it’s not always possible to have all of these diagrams together, we decided to give you this complete pack. Manufacturers of refrigerants, controls, and other suppliers distribute hundreds of thousands of pressure-temperature charts to the trade every year. It woul...R448A has a higher cooling capacity (Qe) than the R404A as it is composed of the hydrofluorocarbons (HFCs) R32 [6,21,23] and has a lower global warming potential (GWP) than the R404A, which is ...Indeed, the R438A HT compressor presented the highest energy consumption in all tests. As a result that, COP values for the R438A/R744 pair were consistently (30%, approximately) below those of the original system with R134a/R744. Higher GWP and lower COP have thus contributed decisively to a greater environmental impact of the R438A choice. Get the free r438a pt chart form Get Form Show details. Hide details ...

Please select a refrigerant via the drop down menu to display pressure/temperature data. Select a Refrigerant . R-11; R-12; R-13; R-22; R-23; We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on ...Have you ever wanted to create a flow chart in PowerPoint but didn’t know where to start?

Where i need to calculate the enthalpy and plot on a graph.The graph needs to be customized as shown in the pic.Can someone help me with this.I tried it with image insertion ,but required it to plotted in the graph itself.Indeed, the R438A HT compressor presented the highest energy consumption in all tests. As a result that, COP values for the R438A/R744 pair were consistently (30%, approximately) below those of the original system with R134a/R744. Higher GWP and lower COP have thus contributed decisively to a greater environmental impact of the R438A choice.The R438A PT (Pressure-Temperature) chart is typically used by HVAC technicians, refrigeration technicians, and professionals in the heating, …pressure side, etc.). It is also recommended to have spare seals for other components available during restart of the system. The same type of seal can be used; it should just be a new one that has not previously been in R-22 service. A rigorous leak check regime pre- and post-retrofit will minimize any refrigerant losses. Obviously, any seals ...If you like to embroider or do cross stitThe R438A PT (Pressure-Temperature) chart is typically used b Nonflammable Gas Mixture: Halocarbon R438a 1-9999ppm / Nitrogen 99.0001-99. 9999% Not available.
