These charts show the surface pressure pattern using isobars (lines of equal pressure) and indicate areas of high (H) and low pressure (L) along with their central pressure value. Isobars are represented by solid lines. High pressure is usually associated with settled weather while low pressure is normally associated with unsettled weather.

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. Hypertensive crisis. This stage of high blood pressure requires medical attention.
