1.Umthamo wokupholisa we-Cold Storage ubaliwe
Umthamo Obandayo Wokupholisa wesitoreji esibandayo ungabala ukusetshenziswa kokupholisa kwendawo ebandayo, kanye nezimo eziyisisekelo ezidinga ukuhlinzekwa:
Umkhiqizo
Usayizi wokugcina obandayo (ubude * ububanzi * ubude)
Umthamo wokugcina obandayo
Ivolumu yokuthenga: T/D
Isikhathi sokupholisa: amahora
Amazinga okushisa angenayo, °C;
izinga lokushisa eliphumayo, °C.
Ngokusho kokuhlangenwe nakho, ngokusho kobukhulu besitoreji esibandayo, ihlukaniswe ngezimo ezimbili:
Isilinganiso somthwalo wokupholisa wesitoreji esincane esibandayo (ngaphansi kuka-400m3).
Isilinganiso somthwalo wokupholisa wesitoreji esikhulu esibandayo (ngaphezu kuka-400m3).
Umthwalo wokupholisa olinganiselwe wesitoreji esincane esibandayo (ngaphansi kuka-400m3):
Ukushisa kwesitoreji ngaphezu kwe-0℃, izinga lokushisa lokuhwamuka -10℃, 50℃120W/m3;
Ukushisa kwesitoreji -18℃, izinga lokushisa lokuhwamuka -28℃, 50～110W/m3;
Ukushisa kwesitoreji -25℃, izinga lokushisa lokuhwamuka -33℃, 50～100W/m3;
Izinga lokushisa lokugcina lingu-35°C, izinga lokushisa lokuhwamuka lingu-43°C, ithani elingu-1 lithatha indawo engu-7m2, futhi ukusetshenziswa kokupholisa kungu-5KW/ton* ngosuku; isitoreji esibandayo sincane, kukhulu ukusetshenziswa kokupholisa umthamo weyunithi ngayinye.
Umthwalo wokupholisa olinganiselwe wesitoreji esikhulu esibandayo (ngaphezu kuka-400m3):
Kunamasampula amabili esithenjwa sakho:
Ukushisa kwesitoreji 0～4℃, izinga lokushisa lokuhwamuka -10℃
Ngokuzenzakalelayo amapharamitha alandelayo:
Igama lezimpahla: izithelo nemifino;
Umthamo wokugcina (amathani): 0.3 * 0.55 * ivolumu yesitoreji m3;
Umthamo wokuthenga 8%;
Isikhathi sokupholisa amahora angama-24;
Amazinga okushisa angenayo: 25 ℃;
Izinga lokushisa lomkhumbi: 2℃.
Kumapharamitha azenzakalelayo, umthwalo wemishini weshede lokushisa eliphakathi nendawo: 25 ~ 40W/m3; ukucushwa okujwayelekile: amakamelo ama-4 abandayo; Iyunithi efanayo engu-90HP enendawo yokushisa ephakathi nendawo engu-1000㎡*4.5m ukuphakama.
·
Izinga lokushisa elipholile -18 ℃, izinga lokushisa lokuhwamuka -28 ℃
Ngokuzenzakalelayo amapharamitha alandelayo:
Igama lezimpahla: inyama eqandisiwe;
Umthamo wokugcina (amathani): 0.4 * 0.55 * ivolumu yesitoreji m3;
Ivolumu yokuthenga, 5%;
Amahora angu-24 isikhathi sokupholisa;
Izinga lokushisa elingenayo: -8 ℃;
Izinga lokushisa lomkhumbi: -18 ℃.
Kumapharamitha azenzakalelayo, umthwalo wemishini wendawo yokushisa ephansi yi-18-35W/m3; ukucushwa okujwayelekile: izindawo zokugcina ezibandayo ezi-4; 90HP izinga lokushisa eliphansi iyunithi parallel nge low lokushisa ishede 1000㎡*4.5m ukuphakama. Kumapharamitha azenzakalelayo, umthwalo wemishini wendawo yokushisa ephansi: 18 ~ 35W/m3; ukucushwa okujwayelekile: izindawo zokugcina izinto ezibandayo ezi-4, umshini wesikulufa + ECO; I-75HP iyunithi ehambisanayo yokushisa ephansi enendawo yokushisa ephansi engu-1000㎡*4.5m ukuphakama.
Izinyathelo zokuphepha zokukhethwa kwempahla yokugcina ebandayo: i-condenser: ukupholisa okuhwamukayo lapho izimo zokusebenza zishintshashintsha; i-air cooler: isitoreji sokushisa okuphezulu sisebenzisa ukushisa okuphansi okupholisa ifeni, ukushintshanisa ukushisa, i-valve yokwandisa;
i-compressor: i-compressor yokushisa ephansi idonsa isitoreji sokushisa okuphezulu;
umoya oshisayo uncibilikisa Isithwathwa: indawo yokugcina impahla ebanda ngokushesha;
isithwathwa samanzi: izinga lokushisa lamanzi;
i-antifreeze yaphansi: umoya omncane, khipha isitimu ukushisa i-ethylene glycol.
2. Ukukhethwa kweyunithi yokujiya okupholisa:
1. Iyunithi eyodwa kanye nendawo yokugcina impahla eyodwa: umthamo wokupholisa iyunithi = 1.1 × umthamo wokupholisa wesitoreji esibandayo; umthamo wokupholisa ophelele wesistimu: isici sokuceba 1.1-1.15 kufanele sicatshangelwe.
2. Iyunithi eyodwa enezindawo zokugcina izinto eziningi: umthamo wokupholisa weyunithi = 1.07 × isamba somthamo wokupholisa wesitoreji esibandayo; umthamo wokupholisa ophelele wesistimu: u-7% wokulahleka kwepayipi kufanele kucatshangelwe.
3. Iyunithi ehambisanayo enezigcini ezibandayo eziningi: umthamo wokupholisa iyunithi = P × isamba somthamo wokupholisa wesitoreji esibandayo;
Isamba samandla okupholisa wesistimu: ukulahlekelwa kwepayipi ngo-7% kanye ne-coefficient yokusebenza kwendawo yokugcina impahla ngesikhathi esifanayo kufanele kucatshangelwe.
Izimo ezidingekayo zokukhetha isipholile somoya:
Isiqandisi;
ukushisa kwesitoreji esibandayo;
ukushintshana kokushisa;
Isakhiwo se-air cooler;
Usayizi wesitoreji esibandayo, ibanga lokuhlinzekwa komoya;
Indlela ye-Defrost.
Izimo ezidingekayo zokukhetha isibandisi somoya: 1. Isiqandisi: Iziqandisi ezihlukene zinokushintshana kokushisa okuhlukile nokumelana nokucindezela. I-R404a inokushintshaniswa kokushisa okukhulu kuno-R22, cishe u-1%. 2. Izinga lokushisa elibandayo lesitoreji: Lapho liphansi izinga lokushisa lokugcina elibandayo, liba lincane izinga lokushisa elishintshashintshayo futhi likhulu isikhala se-chip. Khetha kahle ukuhlukaniswa kwe-fin kwesipholile somoya: isamba;
Isamba samandla okupholisa wesistimu: ukulahlekelwa kwepayipi ngo-7% kanye ne-coefficient yokusebenza kwendawo yokugcina impahla ngesikhathi esifanayo kufanele kucatshangelwe.
3. Ukushintshanisa ukushisa:
Ukushintshaniswa kokushisa kwe-cooler air ≥ ukusetshenziswa kokupholisa kwesitoreji esibandayo * 1.3 (umphumela wesithwathwa); ukushintshaniswa kokushisa okulinganiselwe: ukushintshanisa ukushisa kusampula × i-coefficient yangempela; ukushintshana kokushisa ngaphansi kwezimo zokuklama: i-nominal exchange Heat × i-coefficient yokulungisa; I-coefficient yokulungiswa kokushisa kwesitoreji: ukwehlisa izinga lokushisa kwesitoreji esibandayo, kuncane ukushintshaniswa kokushisa. Isici sokulungiswa kwezinto eziphelile: impahla kanye nokuqina. I-coefficient yokulungisa ye-fin coating: i-anti-corrosion coating inciphisa ukushintshaniswa kokushisa; I-coefficient yokulungiswa kwevolumu yomoya: izidingo ezikhethekile zefeni.
4. Isakhiwo sokupholisa umoya Uhlobo lwesilingi:evame ukusetshenziswa endaweni yokugcina ebandayo;
uhlobo lwe-ceiling: i-double air outlet, i-air outlet emine, i-air conditioner;
uhlobo lwaphansi: igumbi lokuqandisa elisheshayo, noma isiqandisi sepayipi lomoya.
.Usayizi wendawo yokugcina ebandayo, ibanga lokunikezwa komoya, kanye nosayizi wendawo yokugcina ebandayo, uphephetha umoya ngokulinganayo, futhi unqume inani labalandeli bokupholisa.
5. Ukukhetha indlela yokuncibilikisa isitoreji esibandayo:
| ITHEMPERATURE YOKUGCINA OKUMANDLA | I-DEFROST |
| +5℃ | Ukuncibilika kwemvelo, |
| 0 ~ 4℃ | i-electric defrosting, ukugezwa kwamanzi, |
| -18℃ | i-electric defrosting, ukugezwa kwamanzi, ukuncibilika komoya oshisayo |
| -35 ℃ | i-electric defrosting, ukugezwa kwamanzi, |
