Okpomọkụ ya na ya hà
Na sayensị ikuku, okpomọkụ yiri yá bụ okpomọkụ nke ikuku n'ime ngwugwu nkè a na-ewepụta ikuku mmiri niile site nà usoro adiabatic. 

Mmiri nwèrè mmiri na-esi na mmiri (ọdọ mmiri, oké osimiri, wdg) banye na ya...Ọ dị íchè íchè Ike achọrọ iji mee nke ahụ ewepụla ya n'ikuku. Iwere ikuku dị ukwuu na okpomọkụ T na ngwakọta nkè r, ịcha ya site na condensation ga-eweghachi ike na ikuku. Nkè a ga-adabere na ntọhapụ okpomọkụ zoro ezo dị ka: 

  : okpomọkụ zoro ezo nke evaporation (2400 kJ / kg na 25°C ruo 2600 kJ /kg na -40°C)
  : okpomọkụ a kapịrị ọnụ na nrụgide na-adịgide adịgide màkà ikuku (≈ 1004 J/(kg·K))

Tebụl dị màkà ọnụ ọgụgụ ziri ezi nké coefficients abụọ ikpeazụ.

Hụkwa 

 Okpomọkụ nke mmiri
 Okpomọkụ nwere ike ime
 Okpomọkụ nke ikuku
 Okpomọkụ nwere ike ịha nhata
