Isilawuli se-compressor sokwakha umoya wokungena komoya kanye nesimo somoya

Isilawuli sesivinini esiguquguqukayo se-chiller sikuvumela ukuthi unikeze ukulawulwa kwengcindezi njalo ngenkathi ufanisa umthamo nesidingo sangempela ngokusekelwe kuzilinganiso ohlelweni. Ukulawula isivinini kunenzuzo uma i-compressor isebenza isikhathi eside ngomthwalo oyingxenye. Yehlisa izindleko zokusebenza ngokuqalisa izinhlelo zokusebenza ngesivinini esiphansi esinciphisa ukusetshenziswa kwamandla. Futhi unciphise izindleko zokufaka ngokuthuthukisa uhlelo kanye ne-compressor ngokwayo.

Amadrayivu e-Danfoss AC aqinisekisa ukuqalisa nokuma okumbalwa okunciphisa ukuguga kwemishini. Futhi izici ezizinikele, ezifana nomsebenzi 'weqa i-resonance', zikuvumela ukuthi ubone kalula amaza okushayela ukuze uvimbe umsindo nokulimala.

Imikhiqizo yama-compressor ihlanganisa iziqalisi ezithambile, amadrayivu anamandla amakhulu, amadrayivu e-harmonic aphansi, izihlungi ze-AHF ze-harmonic. Wonke amadrayivu alethwa anezinketho ezakhelwe ngaphakathi zesilawuli se-cascade, amakhoyili e-DC nezilawuli ze-PID.

Esinye sezici zezindleko ezinkulu kumjikelezo wempilo wesistimu yokupholisa amandla. Ezinhlelweni eziningi zokupholisa nesiqandisi, umthamo udlula umthwalo wokushisa ngenxa yokuhluka kwesizini, ukulayishwa komkhiqizo, ukuhluka kokuhlala, nezinto zikagesi ezibangela ukulahleka kwamandla. Amadrayivu esimanje, azinikele e-AC ahlala elungisa umthamo wemishini kumthwalo wangempela wokushisa kanye nezidingo zenqubo. Izinzuzo ziphansi kakhulu ukusetshenziswa kwamandla kanye nezindleko eziphansi zokusebenza nokugcinwa.

I-compressor ehlakaniphile nesilawuli se-condenser/evaporator sibalulekile kunoma iyiphi isistimu yokupholisa elungiselelwe noma yesiqandisi. Ungakwazi ukuzuza ukonga okungu-10–25% ekusetshenzisweni kwamandla ngokusebenzisa amadrayivu e-Danfoss AC ukuze uthuthukise amandla okulawula ama-compressor ayisiqandisi, ama-condensers nama-evaporator. Ngokudala ukuzinza ngenkathi kulinganisa umthamo kumthwalo wangempela, i-system-wide coefficient of performance (COP) ithuthukisa ukunikeza ukonga amandla okubalulekile.

Ukulawulwa kwe-Cascade kuthuthukisa ukonga amandla futhi kunciphisa izindleko zomjikelezo wempilo

Ukucushwa kwe-Cascade kukhiqiza ukusebenzisana okuhle phakathi kohlelo lokusebenza nedrayivu ye-AC ngaphansi kokulayisha ingxenye. Umthwalo wesisekelo uphathwa uhlelo lokusebenza olulodwa, njenge-compressor, elawulwa yidrayivu. Lapho umthwalo wokushisa ukhuphuka, idrayivu iqala ama-compressor engeziwe eyodwa ngesikhathi. Lokhu kuqinisekisa ukuthi izinhlelo zokusebenza zisebenza endaweni yazo esebenza kahle kakhulu, futhi idrayivu igcina ukusebenza kahle kwamandla okuphezulu kulo lonke uhlelo.

Ukulawulwa kwe-Cascade okuhlelwe kahle kuqinisekisa ukuguga okuncane ohlelweni ngalunye. Ngokuzungezisa ama-compressor anamandla amakhulu, isibonelo, abaphathi bezokulungisa bangaqinisekisa ukuthi ngamunye ugcina enenani elifanayo lamahora okusebenza kanye nezinga elilinganayo lokugqoka. Lokhu kwandisa impilo yonke yezinhlelo zokusebenza futhi kwelula izikhawu zesevisi kunciphisa izindleko zomjikelezo wokuphila.

Isilawuli sephakethe se-Multi-zone esithuthukisiwe se-Danfoss Drives siqinisekisa ukukhishwa okusebenzayo nokulawula amaphekhi e-compressor afika kwayisithupha. Lokhu kunciphisa ukusetshenziswa kwamandla, kugwema ukwenzeka njalo nokususwa kwesiteji, kuzinzisa izingcindezi namazinga okushisa, futhi kunciphisa ukuguga nokukhala kwe-compressor. Ngokufanayo, Isilawuli sePump Cascade sisabalalisa amahora asebenzayo ngokulinganayo kuwo wonke amaphampu ukuze kugcinwe ukuguga nokudabuka kumaphampu ngamanye abe kuncane.
