Te matauranga noa

1 kcal: 1 kg o te pāmahana wai ka piki, ka heke ranei 1 ℃ i raro i te pehanga o te hau, Ko te wera ka tukuna, ka tukuna ranei he 1 kawhe.

Ma te 1 kirokaramu o te huka ka whiwhi 80 calories

Ko te wera o te kohu o te 1 kirokaramu o te wai he 539 calories

4 ℃ te kiato wai te nui rawa atu

EER/COP/IPLV，te kaha whakamatao/Tauwehenga o te putanga wera ki te mana whakauru.EER te tikanga compressor，COP te tikanga o te punaha，IPLV te tikanga o te taumahatanga o te kaha o te kaha i raro i nga taumahatanga rereke.

IPLV=2.3% * A+41.5% * B + 46.1% * C+10.1% * D （tauwaenga taumaha）
