Yini umehluko phakathi kokupholisa nokushisisa?

Umehluko oyinhloko phakathi kokupholisa nokufudumisa usesendleleni lapho ukushisa kudluliselwa khona. Zombili zisebenzisa isimiso se-heat pump (ezintweni ezifana nama-air conditioner nama-heat pump water heater) noma ukuguqulwa kwamandla ukuze kuhlangatshezwane nezidingo ezahlukene zokushisa. Ukupholisa kuhilela "ukukhipha" ukushisa endaweni engaphakathi bese kukukhiphela ngaphandle ukuze kwehliswe izinga lokushisa langaphakathi: ngokusebenzisa umjikelezo lapho i-refrigerant ivuvukela khona ukumunca ukushisa (uhlangothi lwangaphakathi) bese icindezelwa ukuze ihlangane futhi ikhiphe ukushisa (uhlangothi lwangaphandle), ukushisa okweqile kwangaphakathi kudluliselwa ngaphandle, kugcinwa imvelo epholile, okusetshenziswa kakhulu ukupholisa ehlobo. Ukufudumisa kuphambene - kukhipha ukushisa ngaphandle (indawo enezinga lokushisa eliphansi) bese kukudlulisela ngaphakathi ukuze kwenyuswe izinga lokushisa: noma ngisho nezimo zangaphandle ezibandayo, i-refrigerant ingakwazi ukumunca ukushisa kwezinga eliphansi emoyeni ngokuvuvukela, uyiguqule ibe ukushisa kwezinga eliphezulu nge-compressor compression, bese uyikhipha nge-heat exchanger yangaphakathi ukuze kufezekiswe ukufudumala ebusika; ezinye izinto zikagesi zisebenzisa nokufudumala okungeziwe kukagesi ukuze kukhiqizwe ngqo ukushisa okungeziwe. Ngaphezu kwalokho, kunezehluko ezindleleni zazo zokusebenza nokusetshenziswa kwamandla: ngemodi yokupholisa, i-compressor ne-condenser ye-unit yangaphandle zisebenza ngokugcwele; ngesikhathi sokufudumala, ezinye izinto zidinga ukuvula umsebenzi we-defrosting. Ukusebenza kahle kokufudumala kwe-heat pumps ezindaweni ezinezinga lokushisa eliphansi kuvame ukuba phezulu kune-direct electric heating kodwa kube ngaphansi kune-refrigeration efficiency. Umgomo oyinhloko wobabili ukulungisa izinga lokushisa kwendawo libe yibanga elikhululekile ngokudluliswa kwamandla noma ukuguqulwa, umehluko kuphela usendleleni lapho ukushisa kudluliselwa khona.
