Neu dung it hon 12 tieng thi khong the tiet kiem duoc 60%.

Ong Huong cung thua nhan: “Dan minh rat it phong tieu chuan”.

Chieu "cau khach" tuy vo ly nhung tai tinh

Hau het NTD deu khong he dat ra bat ky mot nghi van nao khi nghe quang cao hap dan tiet kiem toi da toi 60%. Tuy nhien, theo cac nha khoa hoc, viec mot may dieu hoa co the tiet kiem dien toi 60% so voi cac may cung loai la trai voi nguyen tac vat ly. Danh vao tam ly ham re, muon tiet kiem dien cua NTD, nhieu hang san xuat, tung ra cac chieu quang cao “vo ly” nham “cau khach”.

Ngay sau khi TS dat cau hoi voi Tien si Nguyen Van Khai (Cuu Giam doc Trung tam Tu van Den Tiet kiem Dien nang & Dung dich Hoat hoa Dien hoa - Vien Cong nghe Moi truong), ngay lap tuc duoc tien si Khai cuoi tra loi: “Day la kieu noi “dau bung uong nhan sam”… quen mat chu “tac tu” o trang sau. Neu may nay cua ho tiet kiem duoc 60% so voi may doi truoc cua ho thi khach da mua cac may doi truoc se doi ho phai tra lai tien nhu Toyta phai thu hoi lai hon 8 trieu o to”.

Dieu hoa tiet kiem dien 60% co the rat... ton dien!
Quang cao nhu the nay chang khac nao kieu noi “dau bung uong nhan sam”…quen mat chu “tac tu” o trang sau.

Tien si Khai noi: “Tat ca moi vat deu chuyen dong theo cac quy luat vat ly. Trong qua trinh nay, nang luong duoc bien doi tu dang nay sang dang khac, tu vat nay sang vat khac va bao gio cung co su hao phi".

Noi ve cong nghe Inverter, tien si giai thich: "Theo thuat ngu vat ly dien tu thi “Inverter” la ten bo phan ban dan dien tu, bien doi hieu dien the 12V cua nguon dien mot chieu thanh hieu dien the 220V xoay chieu voi tan so 50 HZ hoac voi cac tan so khac ma nguoi ta muon co".

Dai dien LG VN cong bo thong so tieu chuan de dat duoc tiet kiem dien nang 60% so voi may nen khong Inverter nhu sau: Phong du tieu chuan nhu phong oc thi nghiem: Rong 21,5m2, tuong 20 cm2, phong it do toa nhiet (nhu tivi, tu lanh) neu phong nhieu thiet bi dien, khong khi trong phong se nong hon, dieu hoa se phai su dung het cong suat va sinh ra ton dien. Cuc ngoai lap tranh huong dong tay, cuc trong cach mat dat 2,5 – 2,7m. Nhiet do trong nha la 19,5 – 27 do, nhiet do ngoai troi tu 24 – 35 do.

De de hieu, tien si dua ra vi du cu the: Tren noc nha toi hien nay co pin mat troi 70W, hieu dien the mo cao nhat co the dat duoc khi troi nang to la 24V, duoc nap vao ac qui co hieu dien the 1 chieu la 12V.
