Kev paub

1 kcal: 1 kg ntawm dej kub nce los yog poob 1 ℃ nyob rau hauv ib txwm atmospheric siab, Lub tshav kub absorbed los yog tso tawm yog 1 calorie.

1 kg ntawm dej khov tau 80 calories

Cov cua sov ntawm vaporization ntawm 1 kilogram dej yog 539 calories

4 ℃ dej ceev yog qhov loj tshaj plaws

EER / COP / IPLV, lub tub yees muaj peev xwm / Qhov sib piv ntawm cov khoom siv hluav taws xob rau lub zog hluav taws xob.EER txhais tau tias compressor, COP txhais tau tias system, IPLV txhais tau tias qhov hnyav nruab nrab ntawm lub zog ua haujlwm nyob rau hauv qhov sib txawv.

IPLV = 2.3% * A + 41.5% * B + 46.1% * C + 10.1% * D (qhov hnyav nruab nrab)
