Ukuqonda ukubuyiswa kwamandla kuma-rotary heat exchangers - Izinto ezibalulekile zobuchwepheshe ezithinta ukusebenza kahle kwamandla

Izinhlelo zokubuyisa ukushisa zingahlukaniswa ngezigaba ezimbili ngokusekelwe kumapharamitha okushisa esistimu: Izinhlelo zokubuyisa amandla nokuguqulwa kusuka ekushiseni okulahliwe ngamapharamitha aphezulu okushisa (ngaphezu kwama-70).^oC) kanye nezinhlelo zokubuyisa amandla nokuguqulwa kusuka ekushiseni okulahliwe ngamapharamitha okushisa aphansi (ngaphansi kwama-70^oC).

Izinhlelo zokubuyisa ukushisa kanye nokuguqulwa kwamandla ezingaphezu kuka-70^oAma-C asetshenziswa ezinqubweni zobuchwepheshe ezenzeka ezimbonini zamandla, ukudla, amakhemikhali, kanye nezinye izimboni ezisekelwe enqubweni lapho kukhishwa khona ukushisa okukhulu kwemfucuza. Lokhu kushisa kwemfucuza okunemingcele ephezulu yokushisa kungasetshenziswa ukuthuthukisa amandla kanye nokusebenza kahle kwezomnotho kwamabhizinisi ngokushisa umoya ngqo ezinhlelweni zokungenisa umoya noma ngokwandisa izinqubo zobuchwepheshe ezidinga amazinga okushisa aphezulu (isb. umthombo wokushisa wamaphampu okushisa asetshenziselwa ukugcoba imfucuza embonini yokudla, noma ukukhiqizwa kukagesi ezinhlelweni ze-organic Rankine Cycle noma ze-Kalina Cycle). Ukushisa kwemfucuza okunemingcele enjalo yokushisa ephakeme kungasetshenziswa nasezinqubweni zokuqandisa kanye nezokupholisa umoya (isb. ukuguqula amandla okushisa abe ngamanzi abandayo kusetshenziswa ama-chiller okumunca noma okumunca amanzi).

Izinhlelo zokubuyisa ukushisa kanye nokuguqulwa kwamandla ngaphansi kwama-degrees angu-70^oAma-C avame ukusetshenziselwa izinjongo zokufudumala ezakhiweni zokuhlala (isb. ukufudumeza ngaphansi kophahla kusetshenziswa amaphampu okushisa) noma ezakhiweni zezentengiselwano (isb. kumayunithi okuphatha umoya (AHU) ukufudumeza umoya “omusha” noma “wangaphandle” ngokubuyisa ukushisa emoyeni “osetshenzisiwe” noma “okhipha umoya”. Lesi sihloko sizogxila ezicelweni zezakhiwo zezentengiselwano.

Izinhlelo zokubuyisa ukushisa kumayunithi okuphatha umoya zisekelwe ezinhlelweni ezimbili, kuye ngohlobo lwesisombululo esithathwe ekwakhiweni kweyunithi, ezisebenzisa ugesi (izinhlelo ezisebenzayo) noma cha (izinhlelo ezingasebenzi). Izinhlelo zokubuyisa ukushisa ezisebenzayo kumayunithi okuphatha umoya zifaka, isibonelo, izinhlelo ezisekelwe kuma-heat exchanger ajikelezayo noma amaphampu okushisa aguqulwayo. Izinhlelo zokubuyisa ukushisa ezingasebenzi zifaka ama-heat exchanger ahambayo nangama-hexagonal. Isici sokubuyisa ukushisa ezinhlelweni zokungenisa umoya ukuthi ukushisa kutholwa ngomehluko omncane wokushisa phakathi komoya oshisayo ophakeme kanye nomoya oshisayo ophansi, lapho umoya oshisayo ophakeme ungavamile ukudlula ama-30^oC (ezakhiweni zezentengiselwano, ukubuyiselwa kokushisa kwenzeka ngisho noma amazinga okushisa omoya ephansi).

Ngokuvamile, ukubuyiselwa kokushisa kumayunithi okungenisa umoya kanye nama-air-conditioner kwenziwa kusetshenziswa ama-heat exchanger ajikelezayo noma awela phansi (angama-hexagonal), okungavami ukusetshenziswa amaphampu okushisa. Ama-heat exchanger ajikelezayo asetshenziswa kuma-AHU lapho kuvunyelwe ukushintshana ngobuningi phakathi komoya wokungena kanye nomoya ophumayo ku-AHU (lezi ngokuvamile ziyizakhiwo zomphakathi). Ama-heat exchanger awela phansi kanye nama-hexagonal asetshenziswa kumayunithi okuphatha umoya lapho ukushintshana ngobuningi phakathi komoya omusha nosetshenzisiwe kungavunyelwe (isib. izibhedlela). Amaphampu okushisa aguqukayo asetshenziswa lapho kudingeka umoya wokunikeza izinga lokushisa eliphezulu ngezinjongo zokushisa.

Ibhalansi yamandla nesisindo kuma-heat exchanger asetshenziswa kumayunithi okuphatha umoya

Uma kubalwa ukusebenza kwe-rotary heat exchanger ukuze kubuyiselwe ukushisa kumayunithi okuphatha umoya, ngaphezu kwebhalansi yamandla, kudingeka ibhalansi yesisindo efanele. Okulandelayo yizilinganiso zamandla nebhalansi yesisindo zezimo zokugeleza kwesimo esizinzile kanye nokucabanga okulandelayo. Izinguquko zepharamitha eziphindaphindayo ezivela ekunyakazeni kokujikeleza kwe-exchanger zilinganiswa ngokwesilinganiso ku-energy kanye nebhalansi yomswakama iyonke - okungukuthi, izinguquko zendawo eziphindaphindayo ekushiseni kanye nomswakama ebusweni besondo elijikelezayo azibalulekile futhi ngaleyo ndlela azifakwanga ekubalweni.
