Isisombululo soyilo lokugcina izinto ezibandayo

Indawo yokugcina izinto ezibandayo lishishini elisebenzisa amandla amaninzi kumashishini okulungisa nokugcina ukutya okubandayo. Ukusetyenziswa kwamandla kwesakhiwo sokugcina izinto ezibandayo kumalunga ne-30% yendawo yonke yokugcina izinto ezibandayo. Amandla okupholisa kwezinye izakhiwo zokugcina izinto ezibandayo ezinobushushu obuphantsi afikelela kwi-50% yomthwalo uwonke wezixhobo zokukhenkcisa. Ukunciphisa ukulahleka kwamandla okupholisa kwesakhiwo sokugcina izinto ezibandayo, into ephambili kukuseta ngokufanelekileyo umaleko wokukhusela wesakhiwo sokugcina izinto ezibandayo.

01. Uyilo olufanelekileyo lomaleko wokukhusela wesakhiwo sokugcina indawo ebandayo

Izinto ezisetyenziselwa umaleko wokugquma kunye nobukhulu bawo zezona zinto zibalulekileyo ezichaphazela ubushushu, kwaye uyilo lweprojekthi yokugquma lubalulekile ekuchaphazeleni iindleko zobunjineli bokwakha. Nangona uyilo lomaleko wokugquma kwindawo ebandayo kufuneka luhlalutywe kwaye lumiselwe kwiimbono zobugcisa kunye nezoqoqosho, indlela yokusebenza ibonise ukuba "umgangatho" wezinto zokugquma kufuneka ubekwe phambili, emva koko "ixabiso eliphantsi". Asifanele sijonge kuphela iingenelo ezikhawulezileyo zokonga utyalo-mali lokuqala, kodwa sikwacinge ngokonga amandla ixesha elide kunye nokunciphisa ukusetyenziswa.

Kwiminyaka yakutshanje, uninzi lweendawo zokugcina izinto ezibandayo ezilungiselelwe kwangaphambili eziyilwe nezakhiweyo zisebenzisa i-rigid polyurethane (PUR) kunye ne-extruded polystyrene XPS njengeeleya zokufaka izinto ezibandayo [2]. Ukudibanisa iingenelo zokusebenza kwe-PUR kunye ne-XPS's thermal insulation ephezulu kunye nexabiso eliphezulu le-D ye-thermal inertia index yesakhiwo se-brick-concrete, isakhiwo se-civil engineering type single-side color steel plate composite internal thermal insulation layer yindlela yokwakha ecetyiswayo yeleya yokufaka izinto ezibandayo kwisakhiwo se-cold storage enclosure.

Indlela ethile yile: sebenzisa udonga lwangaphandle lwesakhiwo sezitena nekhonkrithi, yenza umaleko womphunga kunye nomsinga emva kokuba i-samente ilinganiswe, uze wenze umaleko wokukhusela i-polyurethane ngaphakathi. Ukulungisa kakhulu indawo yokugcina izinto ezibandayo endala, esi sisisombululo sokonga amandla sesakhiwo esifanele ukulungiswa.

02. Uyilo kunye noyilo lwemibhobho yenkqubo:

Akunakuphepheka ukuba imibhobho yokukhenkceza kunye nemibhobho yamandla okukhanyisa idlule eludongeni lwangaphandle olugqunywe nge-insulation. Indawo nganye eyongezelelweyo yokunqumla ilingana nokuvula umsantsa owongezelelweyo eludongeni lwangaphandle olugqunywe nge-insulation, kwaye ukucutshungulwa kuyinkimbinkimbi, umsebenzi wokwakha unzima, kwaye unokushiya neengozi ezifihlakeleyo kumgangatho weprojekthi. Ke ngoko, kuyilo lwemibhobho kunye nesicwangciso soyilo, inani lemingxunya edlula eludongeni lwangaphandle olugqunywe nge-insulation kufuneka lincitshiswe kangangoko kunokwenzeka, kwaye isakhiwo sogqunywe nge-insulation ekungeneni kodonga kufuneka siphathwe ngononophelo.

03. Ukonga umbane kuyilo kunye nolawulo lweengcango zokugcina izinto ezibandayo:

Ucango lokugcina ubushushu olubandayo lolunye lwezixhobo ezixhasa indawo yokugcina ubushushu obubandayo kwaye luyinxalenye yesakhiwo sendawo yokugcina ubushushu obubandayo esichaphazeleka kakhulu kukuvuza kobushushu obuphantsi. Ngokolwazi olufanelekileyo, ucango lokugcina ubushushu olubandayo lwendawo yokugcina ubushushu obuphantsi luvulwa iiyure ezi-4 phantsi kweemeko ezingama-34 ℃ ngaphandle kwendawo yokugcina ubushushu kunye no-20 ℃ ngaphakathi kwindawo yokugcina ubushushu, kwaye amandla okupholisa afikelela kwi-1 088 kcal/h.

Indawo yokugcina izinto ebandayo ikwindawo enobushushu obuphantsi kunye nomswakama ophezulu kunye notshintsho oluqhelekileyo kubushushu kunye nomswakama unyaka wonke. Umahluko kubushushu phakathi kwendawo yokugcina izinto engaphantsi nangaphakathi udla ngokuba phakathi kwama-40 nama-60 ℃. Xa ucango luvuliwe, umoya ongaphandle kwendawo yokugcina izinto uza kuphuma ungene kwindawo yokugcina izinto kuba ubushushu bomoya obungaphandle kwendawo yokugcina izinto buphezulu kwaye uxinzelelo lomphunga wamanzi luphezulu, ngelixa ubushushu bomoya obungaphakathi kwindawo yokugcina izinto buphantsi kwaye uxinzelelo lomphunga wamanzi luphantsi.

Xa umoya oshushu onobushushu obuphezulu kunye nokufuma okuphezulu ngaphandle kwendawo yokugcina impahla ungena kwindawo yokugcina impahla ngomnyango wokugcina obandayo, ubungakanani obukhulu bokutshintshiselana kobushushu kunye nokufuma kuya kwenza iqabaka lomoya opholileyo okanye umbhobho wokukhupha umoya ophumayo, okubangela ukwehla kokusebenza komphunga, ngaloo ndlela kubangele ukuguquguquka kobushushu kwindawo yokugcina impahla kwaye kuchaphazele umgangatho weemveliso ezigciniweyo.

Amanyathelo okonga umbane kwiingcango zokugcina izinto ezibandayo aquka ikakhulu:

① Indawo yomnyango wokugcina ubanda kufuneka incitshiswe ngexesha loyilo, ingakumbi ukuphakama komnyango wokugcina ubanda kufuneka kuncitshiswe, kuba ukulahleka kobanda kwicala lokuphakama komnyango wokugcina ubanda kukhulu kakhulu kunobubanzi. Phantsi kwemeko yokuqinisekisa ukuphakama kweempahla ezingenayo, khetha umlinganiselo ofanelekileyo wokuphakama komnyango kunye nobubanzi bomnyango, kwaye unciphise indawo yokuvula yomnyango wokugcina ubanda ukuze ufumane isiphumo esingcono sokonga amandla;

② Xa ucango lokugcina izinto ezibandayo luvuliwe, ukulahleka kobushushu kuhambelana nendawo yokuvula ucango. Phantsi kwengcamango yokuhlangabezana nomthamo wokungena nokuphuma kweempahla, umgangatho wokwenziwa ngokuzenzekelayo kocango lokugcina izinto ezibandayo kufuneka uphuculwe kwaye ucango lokugcina izinto ezibandayo kufuneka luvalwe ngexesha elifanelekileyo;

③ Faka ikhethini yomoya obandayo, uze uqalise ukusebenza kwekhethini yomoya obandayo xa ucango lokugcina izinto ezibandayo luvuliwe ngokusebenzisa iswitshi yokuhamba;

④ Faka ikhethini yomnyango we-PVC strip eguquguqukayo kumnyango otyibilikayo wesinyithi osebenza kakuhle ekugqumeni ubushushu. Indlela ethile yile: xa ukuphakama komnyango kungaphantsi kwe-2.2 m kwaye kusetyenziswa abantu kunye neetroli ukudlula, kungasetyenziswa imicu ye-PVC eguquguqukayo enobubanzi obuyi-200 mm kunye nobukhulu obuyi-3 mm. Okukhona izinga lokugqithana phakathi kwemicu liphezulu, kokukhona kungcono, ukuze izithuba phakathi kwemicu zincitshiswe; kwizithuba zomnyango ezinobude obungaphezulu kwe-3.5 m, ububanzi bomcu bunokuba yi-300 ~ 400 mm.
