caut disperata de mult timp 2 ventilatoare: 1) un ventilator care sa bage aer cu capacitate de 100/110 mc h (daca se poate reglabil ar fi extraordinar)- daca e posibil si se gaseste as dori ca acest ventilator sa incalzeasca si aerul daca nu un sistem separat de incalzire fara flacara (cum e un calorifer mic de tot,etc) toate aste adica ventilatoarele si sistemul de incalzire sant pentru un spatiu de doar 1,50 metru cubi 2) un ventilator care sa scoata aerul cu capacitate 90/100 mc h aceste ventilatoare NU o sa lucreze in mediu viciat (fum,abur etc) VA ROG sa ma ajutati (eu stau in Bucuresti ) unde pot cumpara aceste ventilatoare

Buna,100mc/h e destul de mult, vezi atasat pdf-ul, se poate lua de la farnell, ro.farnell.comO formula pentru aproximarea puterii de incalzire/racire necesara: P=AxdTxK , A arie, dT diff. de temperatura, k coeficientpentru tabla vopsita 5.5W/m^2, pentru polyester 3.5W/m^2, daca este in aer liber se dubleaza valoarea obtinuta.
