CO 2 refrigeration (R-744) systems operate at significantly higher pressures compared to legacy hydrofluorocarbon (HFC) systems. For example, on hot summer days, between its medium-temperature ...

Numerical modelling of the rheology of MgO at the pressure, temperature and strain rates of Earth's mantle shows that extremely low strain rates counteract the influence of pressure, so that MgO ...

In high-pressure systems air flows down and out of the center, because of this downward motion it keeps moisture down and usually gives us more pleasant and dry weather conditions.
