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 ...
Anyone approaching an R-744 system must adhere to strict safety precautions. This rings true for several reasons: R-744 can operate at high pressures. On hot days, without adiabatic gas cooling, ...
