Situa\u021bia ini\u021bial\u0103:<\/strong> Proprietarul unui restaurant din Bucure\u0219ti (hol + sal\u0103 de m\u00e2ncare + buc\u0103t\u0103rie deschis\u0103, ~200 mp total) era la cap\u0103tul r\u0103bd\u0103rii \u00een iulie. Temperatura ajunsese la 35\u00b0C, clien\u021bii m\u00e2ncau repede \u0219i plecau, iar buc\u0103t\u0103ria era o saun\u0103. Exista un singur AC vechi de 8 ani, montat doar \u00een hol, cu 12.000 BTU \u2014 complet insuficient pentru ambele spa\u021bii mari.<\/p>\n

Cerin\u021b\u0103:<\/strong> r\u0103corire uniform\u0103 pe toat\u0103 suprafa\u021ba, \u00een v\u00e2rf de sezon, \u00een maxim 48 de ore (restaurant deschis ziua, montaj seara \u0219i noaptea). F\u0103r\u0103 renov\u0103ri majore de pere\u021bi, f\u0103r\u0103 \u00eenchidere zilnic\u0103.<\/p>\n

Ce ne-a zis clientul \u00een prima discu\u021bie<\/h2>\n

*\u201eLa ora 19:00 termin cu clien\u021bii. Voi pute\u021bi lucra p\u00e2n\u0103 la 23:00, iar m\u00e2ine diminea\u021b\u0103, la 10:00, trebuie s\u0103 fie gata. Nu vreau s\u0103 pierd ziua de afaceri. \u0218i tavanele nu mi le demontez \u2014 aia-i tabu. C\u00e2t cost\u0103 s\u0103 nu fac scandal cu muncitorii?”*<\/p>\n

Traducere:<\/strong> sistemul trebuie s\u0103 fie discret (unit\u0103\u021bi interioare mici), montajul rapid (f\u0103r\u0103 freze, cabluri \u00een canale existente unde e posibil) \u0219i sigur (f\u0103r\u0103 improviza\u021bii).<\/p>\n

Solu\u021bia propus\u0103<\/h2>\n

Am ales un sistem multi-split cu 3 unit\u0103\u021bi interioare<\/strong>:<\/p>\n

    \n
  • 2 unit\u0103\u021bi de 18.000 BTU<\/strong> pentru sala de m\u00e2ncare \u0219i hol (montate pe pere\u021bii laterali, la \u00een\u0103l\u021bime)<\/li>\n

  • 1 unitate exterioar\u0103 de 48.000 BTU<\/strong> pe terasa din spate<\/li>\n<\/ul>\n

    De ce multi-split?<\/strong> Fiecare camer\u0103 are termostat independent \u2014 buc\u0103t\u0103ria, care acumuleaz\u0103 mai mult\u0103 c\u0103ldur\u0103, se climatizeaz\u0103 la 19\u00b0C, sala la 22\u00b0C. Nu irosim energie \u00eentr-o \u00eenc\u0103pere care nu are nevoie.<\/p>\n

        Lec\u021bii din acest caz<\/h2>\n

        1. Rutarea cablurilor conteaz\u0103 enorm.<\/strong> Dac\u0103 nu e planificat\u0103 de la \u00eenceput, ajungi cu tuburi la vedere pe to\u021bi pere\u021bii \u0219i cu o zi de munc\u0103 \u00een plus. Noi am folosit canale existente \u0219i suporturi \u00een tavan \u2014 am economisit 8 ore de lucru.<\/p>\n

        2. Multi-split-ul cu mai mult de 2 unit\u0103\u021bi se dimensioneaz\u0103 de la \u00eenceput.<\/strong> Dac\u0103 adaugi o a treia unitate la un sistem dual-split obi\u0219nuit, presiunea agentului frigorific devine instabil\u0103. Aici am pornit cu un compresor de 48.000 BTU dimensionat corect pentru 3 unit\u0103\u021bi interioare.<\/p>\n

        3. Buc\u0103t\u0103ria fierbinte cere aten\u021bie separat\u0103.<\/strong> Un aragaz profesional de 4\u20136 arz\u0103toare emite 3\u20138 kW de c\u0103ldur\u0103. Un AC de 12.000 BTU \u00een zon\u0103 nu face fa\u021b\u0103 singur. Trebuie o unitate separat\u0103 dimensionat\u0103 corespunz\u0103tor, plus<\/strong> ventila\u021bie mecanic\u0103 eficient\u0103 (hot\u0103 puternic\u0103) \u2014 f\u0103r\u0103 aceasta, niciun sistem de climatizare nu e suficient.<\/p>\n

        Implica\u021bii financiare<\/h2>\n
          \n
        • Investi\u021bie:<\/strong> 8.000 RON materiale + 2.000 RON manoper\u0103 = 10.000 RON<\/strong> (amortizare estimat\u0103 \u00een 3 ani din confort crescut \u0219i prelungirea prezen\u021bei clien\u021bilor \u00een sal\u0103).<\/li>\n
        • Echipament:<\/strong> Daikin multi-split inverter (garan\u021bie 5 ani standard, op\u021biune 10 ani extended).<\/li>\n<\/ul>\n

          Epilog (6 luni dup\u0103)<\/h2>\n

          Restaurantul a \u00eenregistrat o cre\u0219tere de ~8% a cifrei de afaceri \u00een var\u0103 fa\u021b\u0103 de acela\u0219i sezon anterior (mai mul\u021bi clien\u021bi stau mai mult \u00een sal\u0103 pe temperaturi pl\u0103cute). Proprietarul a solicitat ulterior instalarea unui sistem de pomp\u0103 de c\u0103ldur\u0103 pentru iarn\u0103. Proiectul s-a amortizat mai repede dec\u00e2t calculul ini\u021bial.<\/p>\n
