Conversia de la R-404A la R-448A<\/a>\u00a0de la magazinul\u00a0din Legan\u00e9s a adus numeroase avantaje:<\/p>\n

\u2022 R-448A \u00eenregistreaz\u0103 rezultate mai bune dec\u00e2t\u00a0R-404A;<\/p>\n

Astfel, s-a putut scoate\u00a0din func\u021biune una dintre cele patru centrale ini\u021biale,\u00a0\u00eentruc\u00e2t s-a redus consumul; de asemenea, s-au\u00a0redus costurile de \u00eentre\u021binere.<\/p>\n

\u2022 Magazinul a pus accentul pe scurgerile de refrieran\u0163i,\u00a0ceea ce a condus la o reducere semnificativ\u0103 a\u00a0acestora (la numai 6%).<\/p>\n
