Njengoba sonke sazi, igumbi elihlanzekile lezemithi linezidingo eziphakeme kakhulu zenhlanzeko nokuphepha. Uma kunothuli egunjini elihlanzekile lezemithi, lizodala ukungcola, ukulimala kwezempilo kanye nezingozi zokuqhuma. Ngakho-ke, ukusetshenziswa kwezihlungi ze-hepa kubalulekile. Yiziphi izindinganiso zokusetshenziswa kwezihlungi ze-hepa, isikhathi sokushintsha, imingcele yokushintsha kanye nezinkomba? Igumbi elihlanzekile elenziwe ngemithi elinezidingo zokuhlanzeka okuphezulu kufanele lizikhethe kanjani izihlungi ze-hepa?
Egunjini elihlanzekile lezemithi, izihlungi ze-hepa zisetshenziswa njengezihlungi ezibulalayo zokwelashwa nokuhlunga komoya ezindaweni zokukhiqiza. Ukukhiqizwa kwe-aseptic kudinga ukusetshenziswa okuyimpoqo kwezihlungi ze-hepa, futhi ukukhiqizwa kwamafomu omthamo oqinile futhi oqinile ngezinye izikhathi kuyasetshenziswa. Amakamelo ahlanzekile emithi ahlukile kwamanye amagumbi ahlanzekile ezimbonini. Umehluko wukuthi lapho kukhiqizwa amalungiselelo nezinto zokusetshenziswa nge-aseptically, hhayi kuphela izinhlayiya ezimisiwe emoyeni okufanele zilawulwe, kodwa futhi inani lama-microorganisms kufanele lilawulwe. Ngakho-ke, uhlelo lwe-air conditioning esitshalweni semithi luphinde lube nokuvala inzalo, ukuvala inzalo, ukukhipha amagciwane nezinye izindlela zokulawula ama-microorganisms ngaphakathi kobubanzi bemithetho efanele. Isihlungi somoya sisebenzisa izinto zokuhlunga ezinezimbobo ukuze sithwebule uthuli ekugelezeni komoya, sihlanze umoya, futhi sihlanze umoya onothuli futhi siwuthumele egumbini ukuze kuqinisekiswe ukuhlanzeka komoya egumbini elihlanzekile. Emakamelweni ahlanzekile emithi anezidingo eziphezulu, izihlungi ze-gel seal hepa zivame ukusetshenziselwa ukuhlunga. Isihlungi se-gel seal hepa sisetshenziswa kakhulu ukuthwebula izinhlayiya ezingaphansi kuka-0.3μm. Inokubekwa uphawu okungcono, ukusebenza kahle kokuhlunga okuphezulu, ukumelana nokugeleza okuphansi, futhi ingasetshenziswa isikhathi eside ukuze kuncishiswe izindleko zezinto ezisetshenziswa kamuva, inikeze umoya ohlanzekile we-workshop ehlanzekile yezinkampani zemithi. Izihlungi ze-Hepa ngokuvamile zihlolwa ukuvuza ngaphambi kokuphuma efekthri, kodwa okungebona ochwepheshe kudingeka banake kakhulu ngesikhathi sokuphatha nokufakwa. Kwesinye isikhathi kuyenzeka ukuthi ukungcola kuvuze kusuka kuhlaka kuya egumbini elihlanzekile ngenxa yokufakwa okungafanele, ngakho ukutholwa kokuvuza kuvame ukwenziwa ngemva kokufakwa ukuze kuqinisekiswe ukuthi okokuhlunga konakele yini; noma ibhokisi liyavuza; ukuthi isihlungi sifakwe kahle yini. Ukuhlolwa okuvamile kufanele futhi kwenziwe ekusetshenzisweni kamuva ukuze kuqinisekiswe ukuthi ukusebenza kahle kokuhlunga kwesihlungi kuhlangabezana nezidingo zokukhiqiza. Izinqubo ezisetshenziswa kakhulu zihlanganisa izihlungi ze-hepa ezincane ze-pleat, izihlungi ze-hepa ezijulile ze-pleat, izihlungi ze-gel seal hepa, njll., ezifeza inhloso yokuhlanzeka ngokuhlunga komoya nokugeleza ukuze kuhlungwe izinhlayiya zothuli emoyeni. Umthwalo wesihlungi (ungqimba) kanye nomehluko wokucindezela okhuphuka nomfula nowaphansi nawo ubalulekile. Uma umehluko wokucindezela okhuphuka nomfula ophansi wesihlungi ukhuphuka, isidingo samandla okunikezwayo kanye nesistimu yomoya yokukhipha umoya izokhuphuka, ukuze kugcinwe inani elidingekayo lezinguquko zomoya. Umehluko onjalo wengcindezi phakathi komfula okhuphukayo nowenza phansi wesihlungi ungase ukhuphule umkhawulo wokusebenza wesistimu yokukhipha umoya. Ngesikhathi sokusetshenziswa, ukuze kuvikelwe isihlungi se-hepa, kufanele kusetshenziswe isihlungi sangaphambili - ngokuvamile isihlungi esihle njengezihlungi ze-F5, F7 kanye ne-F9 (EN779). Isihlungi se-hepa kufanele futhi sishintshwe njalo ukuze kuvikelwe isihlungi se-hepa ekuvalelekeni.
Kungakhathaliseki ukuthi isihlungi se-hepa esifakwe ekupheleni kweyunithi ye-air conditioning yokuhlanza noma isihlungi somoya se-hepa esifakwe ebhokisini le-hepa, lezi kufanele zibe namarekhodi anembile esikhathi sokusebenza kanye nokuhlanzeka kanye nomthamo womoya njengesisekelo sokushintshwa. Isibonelo, ngaphansi kokusetshenziswa okujwayelekile, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu konyaka owodwa. Uma isivikelo sangaphambili sisihle, impilo yesevisi yesihlungi se-hepa ingaba ngaphezu kweminyaka emibili ngaphandle kwenkinga. Yiqiniso, lokhu kubuye kuncike kwikhwalithi yesihlungi somoya we-hepa, noma ngisho nangaphezulu. Izihlungi ze-hepa ezifakwe emishinini yegumbi ehlanzekile, njengezihlungi ze-hepa egumbini leshawa yomoya, zingaba nempilo yesevisi engaphezu kweminyaka emibili uma isihlungi esiyinhloko esingaphambili sivikelwe kahle; isibonelo, izihlungi ze-hepa ebhentshini lokusebenza lokuhlanza zingashintshwa ngokusheshisa kwegeji yomehluko wengcindezi ebhentshini lokusebenzela lokuhlanza. Izihlungi ze-hepa eshedini elihlanzekile zinganquma isikhathi esingcono kakhulu sokushintsha izihlungi zomoya ngokuthola isivinini somoya sezihlungi zomoya ze-hepa. Isibonelo, izihlungi zomoya ze-hepa kuyunithi yesihlungi sabalandeli be-FFU zingathathelwa indawo yiziyalezo ohlelweni lokulawula lwe-PLC noma igeji yomehluko wokucindezela. Izimo zokushintshwa kwezihlungi ze-hepa ezimbonini zokwenza imithi ezibalulwe ezincazelweni zesakhiwo segumbi elihlanzekile yilezi: isivinini sokugeleza komoya sincishiswa sibe esilinganiselwe, ngokuvamile sibe ngaphansi kuka-0.35m/s; ukumelana kufinyelela izikhathi ezi-2 inani lokuqala lokumelana, futhi ngokuvamile lisethwa izikhathi ezingu-1.5 ngamabhizinisi; uma kukhona ukuvuza okungenakulungiseka, amaphuzu okulungisa akufanele adlule amaphuzu angu-3, futhi indawo ephelele yokulungisa akufanele idlule i-3%. Ukuze uthole indawo eyodwa yokulungisa iphuzu, akufanele ibe mkhulu kuno-2 * 2cm. Abanye babafaki bethu besihlungi somoya abanolwazi bafinyeze ulwazi olubalulekile. Lapha sithanda ukwethula izihlungi ze-hepa zamafekthri ezenza imithi. Sithemba ukuthi lokhu kuzokusiza ukuthi ubambe isikhathi esingcono kakhulu sokushintsha izihlungi zomoya ngokunembe kakhudlwana. Kuyunithi ye-air conditioning, lapho i-gauge yokuhlukanisa ingcindezi ibonisa ukuthi ukumelana kwesihlungi somoya kufinyelela izikhathi ezi-2 kuya kwezi-3 ukumelana kokuqala, isihlungi somoya kufanele sigcinwe noma sishintshwe. Uma ingekho igeji yokuhlukanisa ingcindezi, ungasebenzisa ifomethi elandelayo yemizimba emibili ukuze unqume ukuthi idinga ukushintshwa: bheka umbala wezinto zokuhlunga emaceleni omoya angaphezulu nangaphansi kwesihlungi somoya. Uma umbala wezinto zokuhlunga endaweni yokukhipha umoya uqala ukuba mnyama, kufanele ulungiselele ukuwushintsha; thinta okokuhlunga ohlangothini lwe-air outlet yesihlungi somoya ngesandla sakho. Uma kukhona uthuli oluningi esandleni sakho, kufanele ulungiselele ukukushintsha; rekhoda isimo sokushintsha kwesihlungi somoya izikhathi eziningi futhi ufingqe umjikelezo ongcono kakhulu wokushintsha; uma umehluko wengcindezi phakathi kwegumbi elihlanzekile negumbi eliseduze lehla kakhulu ngaphambi kokuba isihlungi somoya se-hepa sifinyelele ukumelana kokugcina, kungase kube ukuthi ukumelana kwezihlungi eziyinhloko nesesibili kukhulu kakhulu, futhi kufanele ulungiselele ukuyifaka esikhundleni; uma ukuhlanzeka ekamelweni elihlanzekile kungahlangabezani nezidingo zokuklama, noma kukhona ukucindezela okungalungile, futhi izihlungi zomoya eziyinhloko nezesibili azizange zifinyelele isikhathi sokushintsha, kungenzeka ukuthi ukumelana nesihlungi somoya we-hepa kukhulu kakhulu, futhi kufanele ulungiselele ukuyibeka esikhundleni.
Ngaphansi kokusetshenziswa okuvamile, isihlungi se-hepa sishintshwa kanye njalo eminyakeni engu-1 kuya kwemi-2 (kuya ngekhwalithi yomoya ezindaweni ezihlukene), futhi le datha iyahluka kakhulu. Idatha yobufakazi ingatholakala kuphela kuphrojekthi ethile ngemva kokuqinisekiswa kokusebenza kwegumbi elihlanzekile, futhi idatha yobufakazi efanele igumbi elihlanzekile inganikezwa kuphela ekamelweni elihlanzekile leshawa yomoya. Izinto ezithinta impilo yesevisi yesihlungi se-hepa:
1. Izici zangaphandle:
1. Imvelo yangaphandle. Uma kunomgwaqo omkhulu noma umgwaqo ongaphandle kwekamelo elihlanzekile, kunothuli oluningi, oluzothinta ngokuqondile ukusetshenziswa kwesihlungi se-hepa futhi ukuphila kuzoncishiswa kakhulu. (Ngakho-ke, ukukhetha indawo kubaluleke kakhulu)
