Isiokwu gbasara ọnụọgụ arụmọrụ nke igwe oyi
Igwe oyi bụ igwe nke na-ebuga okpomọkụ site n'ebe dị ala, wee bufee ya na mpaghara dị elu. Ka usoro a wee mee, igwe ahụ ga-arụ ọrụ ahụ n'ihi na okpomọkụ na-esi n'okpomọkụ dị elu na-asọpụta site na obere okpomọkụ. Nke a bụ site na okwu Clausius:
Ọ gaghị ekwe omume ka igwe oyi bufee okpomọkụ site n'ebe dị ala gaa n'ebe dị oke okpomọkụ, na-enweghị ọrụ (Iwu nke abụọ nke thermodynamics - nkwupụta Clausius).
Igwe a na-arụ ọrụ (W) iji bufee okpomọkụ, site na obere okpomọkụ (Q L ) gaa na oke okpomọkụ (Q H ). Dabere na nchekwa ike, Q L + W = Q H.
Ọ bụrụ na injin okpomọkụ ejiri okwu arụmọrụ mee ihe, mgbe ahụ refrigerant na-eji okwu coefficient nke arụmọrụ (C P ). Coefficient nke arụmọrụ (C P ) nke refrigerant bụ oke dị n'etiti okpomọkụ ebufere site na obere okpomọkụ (Q L ) gaa na ọrụ (W), nke a na-eme iji bufee okpomọkụ.
Oke arụmọrụ nke igwe oyi kacha mma:
TL = obere okpomọkụ, TH = okpomọkụ dị elu
