I-Esensi Yokupholisa: Ukuqhamuka Okungakhethi Kwe-Heat Transfer Ebuyela Emuva

Ukupholisa ngokuyinhloko kuyinqubo yokudlulisa ukushisa ephambene, okusho ukudluliswa kokushisa ukusuka endaweni enezinga lokushisa eliphansi kuya endaweni enezinga lokushisa eliphezulu. Ezimweni zemvelo, ukushisa njalo kulandela umthetho wesibili wezokushisa, kudluliselwa ezinto ezinezinga lokushisa eliphezulu kuya ezingeni lokushisa eliphansi. Ngakho-ke, le nqubo yokudlulisa ukushisa ephambene ayikwazi ukwenzeka ngokungazelelwe futhi kumele ithembele kumishini yangaphandle ukuhlinzeka ngogesi ukuze kufezwe. Phakathi kwalezi, umjovo wokupholisa usebenza njengengxenye eyinhloko. Ngokusebenzisa amandla ngendlela yomsebenzi wezinto ezisebenzayo, uphula umthetho wemvelo wokudlulisa ukushisa, uqhubela ukushisa ukuthi kudluliselwe endaweni enezinga lokushisa eliphansi edinga ukupholiswa (njengendawo yokugcina yokupholisa noma iyunithi yangaphakathi ye-air conditioner) kuya endaweni yangaphandle enezinga lokushisa eliphezulu, ekugcineni kufezwa umphumela wokupholisa endaweni eqondiwe. Ukudluliswa Kokushisa Okuphambene: Umqondo Oyisisekelo Nezimo Zokufezwa Kwenqubo Yokupholisa. I-essence eyinhloko yokupholisa itholakala enprocess yokudlulisa ukushisa ephambene—ukuphula umthetho wemvelo othi ukushisa kudlulela ngokuzithandela ukusuka ezindaweni ezinezinga lokushisa eliphezulu kuya ezindaweni ezinezinga lokushisa eliphansi futhi kuphoqelela ukushisa ukuthi kudluliselwe ezindaweni ezinezinga lokushisa eliphansi kuya ezindaweni ezinezinga lokushisa eliphezulu. Njengoba le nqubo ihambisana ne-tendency ye-thermodynamic yokuzithandela, ayikwazi ukuqedwa ngokuzimela futhi kumele ithembele ekungeneleleni kwemishini yangaphandle: umjovo wokupholisa uhlinzeka ngesisekelo samandla esidingekayo ngezindlela ezifana nokucindezela ama-refrigerants kanye nomsebenzi ophindaphindiwe, udlula ibhodi lamandla enqubo yokudlulisa ukushisa, futhi ekugcineni udlulisa kahle ukushisa ukusuka endaweni enezinga lokushisa eliphansi kuya endaweni enezinga lokushisa eliphezulu. Ngakho-ke, ifezwa umsebenzi wokupholisa nokupholisa, okuyinto eyinhloko yokusebenza kwemishini yokupholisa ehlukene (njengama-fridge kanye ne-air conditioners).
