Malamalama masani
1 kcal: 1 kilokalama o le vevela o le vai siitia pe pa'ū 1 ℃ i lalo o le mamafa masani o le ea, O le vevela e faʻafefe pe faʻamalolo e 1 kaloli.
1 kilokalama o le aisa e maua ai le 80 kaloli
O le vevela o le ausa o le 1 kilokalama o le vai e 539 kalori
4 ℃ vai vai e sili ona telē
EER/COP/IPLV,tulaga fa'a'aisa/fuafa'atatau ole vevela e fa'aulu ile malosiaga fa'aulu.EER o lona uiga compressor,COP o lona uiga ole faiga,IPLV o lona uiga o le mamafa o le malosi o le malosi i lalo o uta eseese.
IPLV=2.3% * A+41.5% * B + 46.1% * C+10.1% * D (aveve mamafa)
