kawruh umum
1 kkal: 1 kg suhu banyu munggah utawa mudhun 1 ℃ ing tekanan atmosfer normal, panas digunakke utawa dirilis 1 kalori.
1 kilogram es entuk 80 kalori
Kalor penguapan 1 kilogram banyu yaiku 539 kalori
Kapadhetan banyu 4 ℃ paling gedhe
EER / COP / IPLV, kapasitas refrigerasi / Rasio output panas kanggo daya input.EER tegese kompresor, COP tegese sistem, IPLV tegese rata-rata bobot efisiensi energi ing macem-macem beban.
IPLV=2,3% * A+41,5% * B + 46,1% * C+10,1% * D (rata-rata bobot)
