Ungayikhetha njani inkqubo yokugcina izinto ezibandayo kunye nenkqubo yokugcina izinto ezibandayo?

1. Ubungakanani bokuphola obubandayo bubaliwe
Umthamo wokupholisa obandayo kwindawo yokugcina ebandayo unokubala ukusetyenziswa kokupholisa kwendawo yokugcina ebandayo, kunye neemeko ezisisiseko ekufuneka zibonelelwe:
Imveliso
Ubungakanani bendawo yokugcina ebandayo (ubude * ububanzi * ukuphakama)
Umthamo wokugcina ubanda
Umthamo wokuthenga: T/D
Ixesha lokuphola: iiyure
Ubushushu obungenayo, °C;
ubushushu obuphumayo, °C.
 
Ngokwamava, ngokobungakanani bendawo yokugcina izinto ezibandayo, yahlulwe yaba ziimeko ezimbini:
Uqikelelo lomthwalo wokupholisa kwindawo yokugcina izinto ezibandayo encinci (ngaphantsi kwe-400m3).
Uqikelelo lomthwalo wokupholisa kwindawo yokugcina izinto ezibandayo enkulu (ngaphezulu kwe-400m3).
 
Umlinganiselo oqikelelweyo womthwalo wokupholisa kwindawo yokugcina izinto ezibandayo encinci (ngaphantsi kwe-400m3):

Ubushushu bokugcina bungaphezulu kwe-0℃, ubushushu bokufuma -10℃, 50～120W/m3;
Ubushushu bokugcina -18℃, ubushushu bokufuma -28℃, 50～110W/m3;
Ubushushu bokugcina -25℃, ubushushu bokufuma -33℃, 50～100W/m3;
Ubushushu bokugcina buyi-35°C, ubushushu bokufuma buyi-43°C, itoni e-1 ithatha indawo ye-7m2, kwaye ukusetyenziswa kokupholisa yi-5KW/ton*ngemini; okukhona indawo yokugcina ebandayo incinci, kokukhona ukusetyenziswa kokupholisa kukhulu ngeyunithi nganye.
 
Umlinganiselo oqikelelweyo womthwalo wokupholisa kwindawo yokugcina izinto ezibandayo ezinkulu (ngaphezulu kwe-400m3):
 
Kukho imizekelo emibini onokuyisebenzisa:
Ubushushu bokugcina 0～4℃, ubushushu bokufuma -10℃
Ngokuzenzekelayo ezi parameter zilandelayo:
Igama leempahla: iziqhamo nemifuno;
Umthamo wokugcina (iitoni): 0.3*0.55*umthamo wokugcina m3;
Umthamo wokuthenga yi-8%;
Ixesha lokupholisa iiyure ezingama-24;
Ubushushu obungenayo: 25 ℃;
Ubushushu bokuthumela: 2℃.
Kwiiparameters ezimiselweyo, umthwalo woomatshini wendawo yokugcina ubushushu obuphakathi: 25 ~ 40W/m3; uqwalaselo oluqhelekileyo: amagumbi ama-4 abandayo; iyunithi ehambelanayo ye-90HP enendlu yokugcina ubushushu obuphakathi eyi-1000㎡*4.5m ukuphakama.

Ubushushu bokupholisa -18℃, ubushushu bokufuma -28℃
 
Ngokuzenzekelayo ezi parameter zilandelayo:
Igama leempahla: inyama ekhenkcezisiweyo;
Umthamo wokugcina (iitoni): 0.4*0.55*umthamo wokugcina m3;
Umthamo wokuthenga, 5%;
Ixesha lokupholisa iiyure ezingama-24;
Ubushushu obungenayo: -8 ℃;
Ubushushu bokuthumela: -18℃.
Kwiiparameters ezimiselweyo, umthwalo woomatshini wendawo yokugcina izinto ezinobushushu obuphantsi yi-18-35W/m3; uqwalaselo oluqhelekileyo: ii-warehouses ezibandayo ezi-4; iyunithi ehambelanayo yobushushu obuphantsi ye-90HP ene-warehouse enobushushu obuphantsi eyi-1000㎡*4.5m ukuphakama. Kwiiparameters ezimiselweyo, umthwalo woomatshini wendawo yokugcina izinto ezinobushushu obuphantsi: 18 ~ 35W/m3; uqwalaselo oluqhelekileyo: ii-warehouses ezibandayo ezi-4, umatshini wezikrufu + i-ECO; iyunithi ehambelanayo yobushushu obuphantsi ye-75HP ene-warehouse enobushushu obuphantsi eyi-1000㎡*4.5m ukuphakama.
 
Amanyathelo okukhetha izixhobo zokugcina izinto ezibandayo: i-condenser: ukupholisa okubangelwa kukufuma xa iimeko zokusebenza zitshintshatshintsha; i-air cooler: indawo yokugcina izinto ezishushu kakhulu isebenzisa ifeni yokupholisa eshushu ephantsi, utshintshiselwano lobushushu, ivalvu yokwandisa;
isigqubuthelo: isigqubuthelo sobushushu obuphantsi sitsala indawo yokugcina ubushushu obuphezulu;
Umoya oshushu uyanyibilika Iqabaka: indawo yokugcina izinto eqandisa ngokukhawuleza;
iqabaka elikhupha amanzi: ubushushu bamanzi;
i-antifreeze yomgangatho: umoya ongenisa umoya, umphunga wokukhupha umoya ukuze kufudunyezwe i-ethylene glycol.
 
2. Ukukhetha iyunithi yokufunxa okupholileyo:

1. Iyunithi enye kunye nendawo yokugcina impahla enye: umthamo wokupholisa weyunithi = 1.1 × umthamo wokupholisa weendawo zokugcina ezibandayo; umthamo wokupholisa uwonke wenkqubo: ubutyebi bento 1.1-1.15 kufuneka buqwalaselwe.
2. Iyunithi enye eneendawo zokugcina izinto ezininzi: umthamo wokupholisa weyunithi = 1.07 × isimbuku somthamo wokupholisa wendawo yokugcina izinto ezibandayo; umthamo wokupholisa uwonke wenkqubo: i-7% yokulahleka kwepayipi kufuneka iqwalaselwe.
3. Iyunithi ehambelanayo eneendawo zokugcina izinto ezibandayo ezininzi: umthamo wokupholisa weyunithi = P × isimbuku somthamo wokupholisa weendawo zokugcina izinto ezibandayo;
Umthamo wokupholisa uwonke wenkqubo: ukulahleka kwepayipi ye-7% kunye ne-coefficient yokusebenza kwe-warehouse kwixesha elifanayo kufuneka kuqwalaselwe.
 
Iimeko eziyimfuneko zokukhetha i-air cooler:
Isiqandisi;
ubushushu bokugcina obubandayo;
ukutshintshiselana kobushushu;
Ulwakhiwo lwesibandisi somoya;
Ubungakanani bokugcina ubushushu, umgama womoya osetyenziswayo;
Indlela yokunyibilikisa.
 
Iimeko eziyimfuneko zokukhetha i-air cooler: 1. I-Refrigerant: Ii-refrigerant ezahlukeneyo zinotshintsho lobushushu olwahlukileyo kunye nokumelana noxinzelelo. I-R404a inotshintsho lobushushu olukhulu kune-R22, malunga ne-1%. 2. Ubushushu bokugcina ubushushu: Okukhona ubushushu bokugcina ubushushu buphantsi, kokukhona utshintsho lobushushu luncinci kwaye kokukhona isithuba se-chip sikhulu. Khetha ngokuchanekileyo isithuba se-fin ye-air cooler: isixa;
Umthamo wokupholisa uwonke wenkqubo: ukulahleka kwepayipi ye-7% kunye ne-coefficient yokusebenza kwe-warehouse kwixesha elifanayo kufuneka kuqwalaselwe.
 
3. Utshintshiselwano lobushushu:

Ukutshintshiselana kobushushu kwe-air cooler ≥ ukusetyenziswa kokupholisa kwendawo yokugcina ebandayo * 1.3 (isiphumo seqabaka); ukutshintshiselana kobushushu okuqhelekileyo: ukutshintshiselana kobushushu kwisampulu × i-coefficient yokwenyani; ukutshintshiselana kobushushu phantsi kweemeko zoyilo: ukutshintshiselana okuqhelekileyo i-coefficient yokulungisa ubushushu ×; i-coefficient yokulungisa ubushushu bokugcina: okukhona ubushushu bokugcina buphantsi, kokukhona utshintshiselana kobushushu buncinci. I-Fin material correction factor: izinto kunye nobukhulu. I-coefficient yokulungisa ye-fin coating: i-anti-corrosion coating inciphisa ukutshintshiselana kobushushu; i-coefficient yokulungisa umthamo womoya: iimfuno ezikhethekileyo zefeni.
 
4. Isakhiwo somoya opholileyo Uhlobo lwesilingi:isetyenziswa kakhulu kwindawo yokugcina izinto ebandayo;

uhlobo lophahla: iplagi yomoya ephindwe kabini, iplagi yomoya emine, i-air conditioner;

uhlobo lomgangatho: igumbi lokukhenkceza ngokukhawuleza, okanye ifriji yepayipi yomoya.

Ubungakanani bendawo yokugcina umoya obandayo, umgama womoya okhoyo, kunye nobungakanani bendawo yokugcina umoya obandayo, zivuthela umoya ngokulinganayo, kwaye zichonge inani leefeni zokupholisa.
 
5. Ukukhetha indlela yokunyibilikisa iqhwa kwindawo ebandayo yokugcina:
