Ungakhetha kanjani uhlelo lokugcina izinto ezibandayo kanye nohlelo lokugcina izinto ezibandayo?

1. Umthamo wokupholisa wesitoreji esibandayo ubaliwe
Umthamo wokupholisa obandayo wesitoreji esibandayo ungabala ukusetshenziswa kokupholisa kwesitoreji esibandayo, kanye nezimo eziyisisekelo okudingeka zinikezwe:
Umkhiqizo
Usayizi wendawo yokugcina ebandayo (ubude * ububanzi * ukuphakama)
Umthamo wokugcina obandayo
Umthamo wokuthenga: T/D
Isikhathi sokupholisa: amahora
Izinga lokushisa elingenayo, °C;
izinga lokushisa eliphumayo, °C.
 
Ngokusho kokuhlangenwe nakho, ngokuya ngobukhulu bendawo yokugcina ebandayo, ihlukaniswe ngezimo ezimbili:
Ukulinganiselwa komthwalo wokupholisa wesitoreji esincane esibandayo (ngaphansi kuka-400m3).
Ukulinganiselwa komthwalo wokupholisa wesitoreji esikhulu esibandayo (ngaphezu kuka-400m3).
 
Umthwalo olinganiselwe wokupholisa wesitoreji esincane esibandayo (ngaphansi kuka-400m3):

Izinga lokushisa lokugcina lingaphezu kuka-0℃, izinga lokushisa lokuhwamuka -10℃, 50～120W/m3;
Izinga lokushisa lokugcina -18℃, izinga lokushisa lokuhwamuka -28℃, 50～110W/m3;
Izinga lokushisa lokugcina -25℃, izinga lokushisa lokuhwamuka -33℃, 50～100W/m3;
Izinga lokushisa lokugcina lingu-35°C, izinga lokushisa lokuhwamuka lingu-43°C, ithani eli-1 lithatha indawo engu-7m2, kanti ukusetshenziswa kokupholisa kungu-5KW/ton* ngosuku; uma indawo yokugcina ebandayo incane, ukusetshenziswa kokupholisa kukhulu ngeyunithi ngayinye.
 
Umthwalo olinganiselwe wokupholisa wesitoreji esikhulu esibandayo (ngaphezu kuka-400m3):
 
Kunezibonelo ezimbili zereferensi yakho:
Izinga lokushisa lokugcina 0～4℃, izinga lokushisa lokuhwamuka -10℃
Ngokuzenzakalelayo amapharamitha alandelayo:
Igama lezimpahla: izithelo nemifino;
Umthamo wesitoreji (amathani): 0.3*0.55*ivolumu yesitoreji m3;
Umthamo wokuthenga 8%;
Isikhathi sokupholisa amahora angama-24;
Izinga lokushisa elingenayo: 25 ℃;
Ukushisa kokuthumela: 2℃.
Kumapharamitha azenzakalelayo, umthwalo womshini wendlu yokugcina izinto ezinokushisa okuphakathi: 25 ~ 40W/m3; ukucushwa okujwayelekile: amakamelo abandayo angu-4; iyunithi ehambisanayo engu-90HP enendlu yokugcina izinto ezinokushisa okuphakathi engu-1000㎡*4.5m ukuphakama.

Izinga lokushisa lokupholisa -18℃, izinga lokushisa lokuhwamuka -28℃
 
Ngokuzenzakalelayo amapharamitha alandelayo:
Igama lezimpahla: inyama eqandisiwe;
Umthamo wesitoreji (amathani): 0.4*0.55*ivolumu yesitoreji m3;
Umthamo wokuthenga, 5%;
Isikhathi sokupholisa samahora angama-24;
Izinga lokushisa elingenayo: -8 ℃;
Izinga lokushisa lokuthumela: -18℃.
Kumapharamitha azenzakalelayo, umthwalo womshini wendawo yokugcina izinto enezinga lokushisa eliphansi ungu-18-35W/m3; ukucushwa okuvamile: izindawo zokugcina izinto ezine ezibandayo; iyunithi ehambisanayo yokushisa okuphansi engu-90HP enegumbi lokugcina izinto elinezinga lokushisa eliphansi elingu-1000㎡*4.5m ukuphakama. Kumapharamitha azenzakalelayo, umthwalo womshini wendawo yokugcina izinto enezinga lokushisa eliphansi: 18 ~ 35W/m3; ukucushwa okuvamile: izindawo zokugcina izinto ezine ezibandayo, umshini wesikulufu + i-ECO; iyunithi ehambisanayo yokushisa okuphansi engu-75HP enegumbi lokugcina izinto elinezinga lokushisa eliphansi elingu-1000㎡*4.5m ukuphakama.
 
Izinyathelo zokuphepha zokukhetha imishini yokugcina ebandayo: i-condenser: ukupholisa okuhwamukayo lapho izimo zokusebenza zishintshashintsha; i-air cooler: isitoreji sokushisa okuphezulu sisebenzisa ifeni yokupholisa eshisayo ephansi, ukushintshana kokushisa, i-valve yokwandisa;
i-compressor: i-compressor yokushisa okuphansi idonsa indawo yokugcina ukushisa okuphezulu;
Umoya oshisayo uyancibilika Iqhwa: indawo yokugcina izinto eqandisa ngokushesha;
iqhwa elikhipha amanzi: izinga lokushisa lamanzi;
isivikelo sokuqandisa phansi: umoya ongenisa umoya, umusi wokukhipha umoya ukuze kufudunyezwe i-ethylene glycol.
 
2. Ukupholisa ukupholisa Ukukhetha kweyunithi:

1. Iyunithi eyodwa kanye nendawo yokugcina impahla eyodwa: umthamo wokupholisa weyunithi = 1.1 × umthamo wokupholisa wesitoreji esibandayo; umthamo wokupholisa ophelele wesistimu: isici sokunotha 1.1-1.15 kufanele sicatshangelwe.
2. Iyunithi eyodwa enezindawo zokugcina impahla eziningi: umthamo wokupholisa weyunithi = 1.07 × isamba samandla okupholisa wesitoreji esibandayo; umthamo wokupholisa wonke wesistimu: u-7% wokulahlekelwa yipayipi kufanele kucatshangelwe.
3. Iyunithi ehambisanayo enezindawo zokugcina ezibandayo eziningi: umthamo wokupholisa weyunithi = P × inani lomthamo wokupholisa wezindawo zokugcina ezibandayo;
Umthamo wokupholisa ophelele wesistimu: ukulahlekelwa kwepayipi okungu-7% kanye ne-coefficient yokusebenza kwe-warehouse esikhathini esifanayo kufanele kucatshangelwe.
 
Izimo ezidingekayo zokukhetha i-air cooler:
Isiqandisi;
izinga lokushisa lokugcina elibandayo;
ukushintshaniswa kokushisa;
Isakhiwo se-air cooler;
Usayizi wesitoreji esibandayo, ibanga lokunikezwa komoya;
Indlela yokuncibilikisa.
 
Izimo ezidingekayo zokukhetha i-air cooler: 1. I-Refrigerant: Ama-refrigerant ahlukene anokushintshana kokushisa okuhlukile kanye nokumelana nengcindezi. I-R404a inokushintshana kokushisa okukhulu kune-R22, cishe u-1%. 2. Izinga lokushisa lokugcina okubandayo: Uma izinga lokushisa lokugcina okubandayo liphansi, kulapho ukushintshana kokushisa kuba kuncane futhi kulapho isikhala se-chip siba sikhulu. Khetha kahle isikhala se-fin ye-air cooler: isamba;
Umthamo wokupholisa ophelele wesistimu: ukulahlekelwa kwepayipi okungu-7% kanye ne-coefficient yokusebenza kwe-warehouse esikhathini esifanayo kufanele kucatshangelwe.
 
3. Ukushintshana kokushisa:

Ukushintshana kokushisa kwe-air cooler ≥ ukusetshenziswa kokupholisa kwesitoreji esibandayo * 1.3 (umphumela weqhwa); ukushintshana kokushisa okujwayelekile: ukushintshana kokushisa kusampula × i-coefficient yangempela; ukushintshana kokushisa ngaphansi kwezimo zokuklama: ukushintshana okujwayelekile I-coefficient yokulungisa ukushisa ×; i-coefficient yokulungisa izinga lokushisa lokugcina: lapho izinga lokushisa lesitoreji esibandayo liphansi, kulapho ukushintshana kokushisa kuncane. Isici sokulungisa izinto ze-Fin: impahla kanye nobukhulu. I-coefficient yokulungisa ye-fin coating: i-anti-corrosion coating inciphisa ukushintshana kokushisa; i-coefficient yokulungisa ivolumu yomoya: izidingo ezikhethekile zefeni.
 
4. Isakhiwo sokupholisa umoya Uhlobo lophahla:evame ukusetshenziswa endaweni yokugcina ebanda;

uhlobo lophahla: indawo yokungenisa umoya ephindwe kabili, indawo yokungenisa umoya emine, indawo yokupholisa umoya;

uhlobo lwephansi: igumbi lokuqandisa ngokushesha, noma ifriji yepayipi lomoya.

Usayizi wendawo yokugcina ebanda, ibanga lokunikezwa komoya, kanye nosayizi wendawo yokugcina ebanda, kushaya umoya ngokulinganayo, bese kunquma inani labalandeli bokupholisa.
 
5. Ukukhetha indlela yokuncibilikisa iqhwa yokugcina ebanda:
