Eòlas coitcheann

1 kcal: 1 kg de theodhachd an uisge ag èirigh no a’ tuiteam 1 ℃ fo chuideam àbhaisteach àile, Is e an teas a thèid a ghlacadh no a leigeil ma sgaoil 1 calorie.

Bidh 1 cileagram de deigh a 'faighinn 80 calaraidhean

Is e an teas vaporization de 1 cileagram uisge 539 calaraidhean

Is e dùmhlachd uisge 4 ℃ an ìre as motha

EER / COP / IPLV ， comas fuarachaidh / Co-mheas toradh teas gu cumhachd cuir a-steach.EER a’ ciallachadh compressor ， COP a ’ciallachadh siostam ， IPLV a’ ciallachadh cuibheasachd le cuideam de èifeachdas lùtha fo luchdan eadar-dhealaichte.

IPLV=2.3% * A+41.5% * B + 46.1% * C+10.1% * D （cuibheasachd le cuideam）
