Isihloko mayelana ne-Coefficient yokusebenza komshini wokupholisa
Umshini wokupholisa umshini othatha ukushisa endaweni enokushisa okuphansi, bese ukuthuthela endaweni enokushisa okuphezulu. Ukuze le nqubo yenzeke, umshini kumele wenze umsebenzi ngoba ukushisa ngokwemvelo kugeleza kusuka ekushiseni okuphezulu kuya ekushiseni okuphansi. Lokhu kungokusho kukaClausius:
Akunakwenzeka ukuthi umshini wokupholisa udlulise ukushisa kusuka endaweni enokushisa okuphansi uye endaweni enokushisa okuphezulu, ngaphandle kokusebenza (Umthetho wesibili we-thermodynamics—Isitatimende sikaClausius).
Umshini usebenza ( W) ukudlulisa ukushisa, kusuka ekushiseni okuphansi (Q L ) kuya ekushiseni okuphezulu (Q H ). Ngokusekelwe ekulondolozweni kwamandla, Q L + W = Q H.
Uma injini yokushisa isebenzisa igama elithi ukusebenza kahle, khona-ke i-refrigerant isebenzisa igama elithi coefficient of performance (C P ). I-coefficient of performance (C P ) ye-refrigerant iyisilinganiso esiphakathi kokushisa okudluliselwe kusuka ekushiseni okuphansi (Q L ) kuya emsebenzini (W), okwenziwa ukudlulisa ukushisa.
Isilinganiso sokusebenza esifanele somshini wokupholisa:
TL = izinga lokushisa eliphansi, TH = izinga lokushisa eliphezulu
