level. See the pressure-temperature charts in this bulletin to compare pressures and temperatures, to calculate superheat or subcooling for the refrigerant. WARNING: Liquid refrigerant entering the compressor at any time during system operation can lead to compressor oil level problems and rapid compressor failure. 8. Monitor oil levels. 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 ...
