Igumbi elibandayo elibandayo ngokukhawuleza linciphisa ubushushu bemveliso ngokukhawuleza. Likhusela umgangatho wokutya kunye nesakhiwo. Amashishini amaninzi ayisebenzisela inyama, ukutya kwaselwandle, kunye nemifuno. Igumbi linciphisa ubushushu obuphakathi ngokukhawuleza. Uninzi lweenkqubo ziqandisa iimveliso ukusuka kwi-+20°C ukuya kwi- –18°C ngokukhawuleza. Ixesha lokubanda lihlala lingaphantsi kweeyure ezi-4. Ukubanda ngokukhawuleza kuthintela ukukhula kwekristale yomkhenkce. Iikristale ezincinci zikhusela ulwakhiwo lweseli. Le nkqubo igcina incasa, umbala, kunye nesondlo. Iifektri ezininzi zifaka amagumbi okuqandisa ngokukhawuleza kwimigca yokucubungula. Igumbi lixhasa imveliso ephezulu kunye nomgangatho ozinzileyo. Abavelisi bokutya baxhomekeke kule nkqubo yokuthumela ngaphandle kunye nokugcina ixesha elide.
Uluhlu lobushushu kunye nokusebenza kokuqandisa kwegumbi elibandayo elikhawulezayo lokuqandisa
Ubushushu bokupholisa kwigumbi elibandayo eliqandisa ngokukhawuleza buhlala buyi-15～-35℃, obufana nobo beindawo yokugcina ebanda kubushushu obuphantsiUmahluko ophambili phakathi kwendawo yokugcina ebanda ngokukhawuleza kunye nendawo yokugcina ebanda kubushushu obuphantsi sisantya sokubanda. Xa kuthelekiswa nesiqheloigumbi elibandayo, igumbi elibandayo eliqhaqhazelisa ngokukhawuleza linokunciphisa ngokukhawuleza ubushushu obuphakathi kwezinto, lizivumele ukuba zidlule ngokukhawuleza kwindawo ephezulu yokuvelisa ikristale yomkhenkce.
Xa kuqandisiwe, uninzi lomswakama ngaphakathi kokutya luqandisiwe kwi -1~-5℃. Ke ngoko, i -1~-5℃ ikwabizwa ngokuba yindawo ephezulu yokuvelisa ikristale yomkhenkce. Kwinkqubo yokuqandisiwe ibe ngumkhenkce, umthamo wamanzi uya kuba mkhulu, kwaye ulwakhiwo lwangaphakathi lokutya okuninzi, kwanohlobo lweproteni, aluyi kuphinda luguqulwe.
Okukhona ubushushu obuphakathi bokutya buhlala ixesha elide kwindawo ephezulu yokwakheka kwekristale yomkhenkce, kokukhona iikristale zomkhenkce ziya kuba ngaphakathi, kwaye kokukhona ukutya kuya kutshatyalaliswa ngokunzulu. Ukutya kuya kulahlekelwa yincasa yako eqinileyo, kwaye nencasa yako yokuqala iya kulahleka. Konke oku kubangelwa ziindlela ezingafanelekanga zokuqandisa. Igumbi lokubanda elibandayo elikhawulezileyo litshintshe indlela yokuphola eyayikade yehlisa kancinci ubushushu obuphakathi kwezinto, kusetyenziswa umoya obandayo omninzi kwiindlela ezahlukeneyo ukudlulisa ngokukhawuleza ubushushu obuphakathi kwezinto kwindawo ephezulu yokuvelisa ikristale yomkhenkce.
Ngale ndlela, kuza kuveliswa iikristale ezinkulu zomkhenkce ngaphandle, kwaye ngaphakathi kuya kuhlala kugcinwe kakuhle. Ke ngoko, ukutya okugcinwe kwigumbi elibandayo eliqhaqhazelisa ngokukhawuleza kunokugcina isakhiwo sako sokuqala kangangoko, kwaye ngokubanzi kube nencasa nencasa engcono.
Iimpawu eziphambili zesakhiwo segumbi elibandayo elikhawulezayo
Igumbi elibandayo elikhawulezayo lisebenzisa ubushushu obunzima. Ubukhulu bephaneli buhlala bufikelela kwi-120 mm ukuya kwi-150 mm. Iiphaneli ze-PU zibonelela ngokuhanjiswa kobushushu malunga ne-0.022 W/m·K. Iiphaneli ze-PIR ziphucula ukumelana nomlilo. Ulwakhiwo lwegumbi luquka iimigangatho eziqinisiweyo. Iimigangatho ziphatha imithwalo ephakathi kwe-2,000 ukuya kwi-5,000 kg/m². I-aluminiyam engatyibilikiyo okanye iindawo zentsimbi engatyibilikiyo zixhasa ukhuseleko.
Iingcango zisebenzisa izakhelo ezishushu. Izifudumezi zeengcango zidla malunga nama-watts angama-60 ukuya kwi-120. Ezi zifudumezi zithintela ukwakheka komkhenkce. Izivalo eziqinileyo zinciphisa ukuvuza komoya. Ubungakanani begumbi buyahluka ngokwezinga lemveliso. Amagumbi amancinci anomlinganiselo wama-20 m². Amagumbi amakhulu emizi-mveliso adlula ama-300 m². Ukuphakama kwesilingi kudla ngokuba phakathi kwe-3 m ukuya kwi-6 m. Isakhiwo esomeleleyo sinciphisa ukwanda kobushushu ngaphezu kwama-25%. Olu khuselo luvumela ukusebenza okuzinzileyo phantsi komahluko omkhulu wobushushu.
Inkqubo yokuFrijisa kunye neenxalenye zeGumbi elibandayo eliKhawulezayo
Inkqubo yokukhenkcisa yinxalenye ephambili yokusebenza kokukhenkcisa ngokukhawuleza, ingakumbi kwigumbi lokubanda elibandayo ngokukhawuleza. Utshintsho lobushushu kwigumbi lokubanda elibandayo ngokukhawuleza alunciphi kancinci. Endaweni yoko, liyehla liye kwi -40 ℃ ngokukhawuleza, emva koko liphinde libuyele esiqhelweni, kwaye ekugqibeleni lilawule ubushushu kwi -18 ℃. Ke ngoko, igumbi lokubanda elibandayo ngokukhawuleza lidla ngokufaka izixhobo zokukhenkcisa ezinamandla aphezulu.
Uninzi lweenkqubo zisebenzisa ii-screw okanye ii-semi-hermetic compressors. Ii-screw compressors zilungele amandla angaphezu kwama-50 kW. Amandla okupholisa ahlala ephezulu. Igumbi elinomkhenkce okhawulezayo elingama-50 m² lidla ngokufuna ama-40 ukuya kuma-60 kW. Igumbi elingama-200 m² linokufuna ama-150 ukuya kuma-250 kW.
Le nkqubo ibandakanya ii-evaporators, ii-condenser, ii-expansion valves, kunye nee-oil separators. Ii-evaporators zisebenzisa isithuba esibanzi se-fin. Isithuba se-fin sidla ngokuba phakathi kwe-8 mm ukuya kwi-12 mm. Olu yilo luthintela ukuvaleka kwe-frost.
Iifriji ziquka i-R404A, i-R507A, kunye ne-ammonia. Iinkqubo ze-ammonia zisebenza kakuhle kakhulu. Iinkqubo ze-ammonia zinciphisa ukusetyenziswa kwamandla nge-15% ukuya kwi-20%. Iifeni ezingaphakathi kwii-evaporators zinika umoya onamandla. Isantya somoya sidla ngokufika kwi-3 ukuya kwi-6 m/s. Umoya ophezulu ususa ubushushu bomphezulu ngokukhawuleza. Le nkqubo iqinisekisa ukubanda ngokukhawuleza nangokulinganayo.
Uyilo lokuhamba komoya kunye nomgangatho wokuqandisa imveliso
Ukuhamba komoya kuchazwa ngokusebenza kakuhle kokukhenkceza. Amagumbi abandayo aqandisa ngokukhawuleza asebenzisa i-convection enyanzelisiweyo. Iifeni zityhala umoya obandayo ngqo phezu kweemveliso. Umthamo oqhelekileyo wokuhamba komoya uphakathi kwama-20,000 ukuya kuma-40,000 m³/h. Isantya somoya esijikeleze iimveliso sihlala sihambelana. Ukuhamba komoya okufanayo kuthintela ukukhenkceza okungalinganiyo.
Umgama phakathi kwemveliso nawo ubalulekile. Iitreyi zihlala zigcina izithuba ezingama-30 ukuya kuma-50 mm. Olu mgama luvumela ukujikeleza komoya. Umgama olungileyo unciphisa ixesha lokukhenkceza ngama-20%. Inkqubo ikhenkceza iimveliso ngokulinganayo. Ubushushu obuphakathi bufikelela kwi--18°C ngokukhawuleza. Ukukhenkceza okungalinganiyo kubangela umonakalo kwimo. Ukuhamba komoya okunamandla kuthintela lo mngcipheko. Iikhenkcezi zomoya zikhokela indlela ukuhamba komoya ngayo. Ezi khenkcezi zinciphisa iindawo ezifileyo. Inkqubo yokuhamba komoya iqinisekisa umgangatho ozinzileyo wokukhenkceza kwibhetshi nganye.
Izicelo kuzo zonke iiShishini zokutya
Amagumbi okubanda akhawulezayo asebenza kwiinkampani ezininzi. Abaqhubi beentlanzi zaselwandle baqandisa iishrimp, intlanzi, kunye ne-squid. Izityalo ezininzi zicubungula iitoni ezi-2 ukuya kwezi-10 ngosuku. Abaqhubi benyama baqandisa inyama yenkomo, inyama yehagu, kunye nenkukhu.
