Indawo yokugcina izinto ezibandayoIindawo zokugcina ukutya zidlala indima ebalulekileyo kwiindlela zanamhlanje zokubonelela ngempahla. Zikhusela umgangatho wokutya, zizinzile amaxabiso, kwaye zixhasa urhwebo oluphakathi kwemimandla ngeempahla ezichaphazeleka bubushushu. Ukusuka kwimveliso entsha ukuya kumayeza, iziseko zokugcina ukutya okubandayo zivumela ukufumaneka nokhuseleko unyaka wonke. Njengoko iipateni zokusetyenziswa zitshintsha kwaye uthungelwano lwezinto ezisetyenziswayo lusanda, imfuno yeendawo zokugcina ukutya ezibandayo ezisebenzayo iyaqhubeka nokukhula.
Imisebenzi ephambili kunye neeParameters zobuchwepheshe zeendawo zokugcina izinto ezibandayo
Indawo yokugcina izinto ezibandayo yenzelwe ukugcina amaqondo obushushu alawulwayo acothisa ukuwohloka kwezinto eziphilayo kunye neekhemikhali. Ububanzi obuqhelekileyo bobushushu bokusebenza buxhomekeke kwiindidi zemveliso. Indawo yokugcina izinto ezibandayo idla ngokusebenza phakathi kwe-0°C kunye ne-+4°C kwinyama entsha, ubisi, kunye nemifuno. Indawo yokugcina izinto ezibandayo idla ngokugcina i-−18°C, ehambelana nemigangatho yokhuseleko lokutya yamazwe ngamazwe. Iindawo zokugcina izinto ezibandayo zokugcina ukutya kwaselwandle okanye inyama ixesha elide zinokusebenza ukusuka kwi-−25°C ukuya kwi-−30°C.
Ukusebenza kobushushu obuphezulu kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwamandla. Iipaneli zesandwich zepolyurethane ezinobushushu obuphezulu obumalunga ne-0.022 W/m·K zihlala zingumgangatho weshishini. Kwiindawo zokugcina izinto ezikhenkcezisiweyo, ubukhulu bobushushu buhlala buqala kwi-120 mm ukuya kwi-150 mm. Ezi parameters zinceda ekunciphiseni ukwanda kobushushu kwaye zinciphise ixesha lokusebenza kwecompressor. Umgangatho uhlala uquka iileya zobushushu obuphakathi kwe-80 mm ukuya kwi-120 mm, zidityaniswe nezithintelo zomphunga ukuthintela ukunyuka kweqabaka.
Iinkqubo zokukhenkcisa zibangela isabelo esikhulu seendleko zokusebenza. Ukusetyenziswa kwamandla kudla ngokumela i-60% ukuya kwi-70% yeendleko zokusebenza zokugcina ubushushu obubandayo. Iinkqubo zokukhenkcisa ze-ammonia zanamhlanje okanye ze-CO₂ zinokufikelela kwixabiso lokusebenza eliphakathi kwe-3.5 kunye ne-5.0 phantsi kweemeko eziphuculweyo. Iidrives ze-variable-frequency kwi-compressors kunye neefeni ze-evaporator zinciphisa ukusetyenziswa kombane nge-15% ukuya kwi-25% xa kuthelekiswa neenkqubo zesantya esimiselweyo.
Uxinano lokugcina luchaza ukusebenza kakuhle kwezoqoqosho. Iindawo zokugcina izinto ezibandayo ezihlala ziphezulu zihlala zifikelela kubude obucacileyo obuziimitha ezingama-20 ukuya kwezingama-35. Iinkqubo zokurhangqa iipalethi ezizenzekelayo zivumela uxinano lokugcina olungaphezulu kwe-0.8 palethi nganye ngemitha yesikwere. Olu setyenziso luthe nkqo lunciphisa ukusetyenziswa komhlaba kwaye lunciphisa iindleko zokwakha ngepalethi nganye. Kwizakhiwo ezidlula izikhundla zeepalethi ezingama-20,000, ukwenziwa kwezinto ngokuzenzekelayo kunokunciphisa imfuno yabasebenzi ngaphezulu kwe-40%.
Ukwakhiwa kweNdawo yokugcina izinto ezibandayo
Iibhodi zokugcina izinto ezibandayo ezisemgangathweni ophezulu zimisela ukusebenza kakuhle. Iiphaneli ze-polyurethane zeprimiyamu zibonelela ngama-R-values angama-28 ukuya kuma-30 ngobukhulu obuziisentimitha ezine kuphela. Olu lawulo luphantsi lobushushu lunciphisa ukungena kobushushu ngama-50 ekhulwini xa kuthelekiswa nezixhobo eziqhelekileyo. Ubushushu obusebenzayo bunciphisa umthwalo womsebenzi we-compressor ngama-35 ekhulwini. Ijoyinti nganye yephaneli ifuna ukutywinwa okugqibeleleyo ukuze kupheliswe ukuvalwa kobushushu. Izithintelo zomswakama zithintela ukufuma okuvelisa ukungunda kwaye kunciphisa ukusebenza. Izibonelelo ezisebenzisa iiphaneli eziphezulu zibika ukuba iindleko zamandla ziyehla ukusuka kwi-$12,000 ukuya kwi-$7,500 ngonyaka kwi-1,000 square feet. Iiphaneli zigcina amaqondo obushushu ukusuka kwi -10°F ukuya kwi-35°F ngokuguquguquka okuncinci.
Umgangatho wezixhobo zefriji uqhuba ezinye izinto eziguquguqukayo zokusebenza. Iicompressor zanamhlanje ezisebenzisa i-semi-hermetic zifikelela kwiireyithingi zokonga amandla ze-3.4 ukuya kwi-11.7 BTU nge-watt-yure nganye. Icompressor isebenzisa iipesenti ezingama-57 zamandla enkqubo iyonke. Iifeni ze-evaporator ezisebenzayo kakhulu zinciphisa ukusetyenziswa kwelo candelo ukusuka kwi-10 ukuya kwi-7 ekhulwini iyonke. Iidrives ze-variable frequency zilungisa isantya seemoto, zinciphisa imijikelo yomsebenzi ukusuka ekusebenzeni rhoqo kwe-100 ukuya kwi-70 ekhulwini phantsi kwemithwalo eqhelekileyo. Abalawuli be-Smart defrost banciphisa ukusebenza kwe-heater ukuya kwi-4.2 ekhulwini yexesha lokusebenza, begcina i-550 kWh ngenyanga.
Ukusebenzisana phakathi kweepaneli eziphezulu kunye nezixhobo kuvelisa iingenelo ezidityanisiweyo. Iinkqubo ezidityanisiweyo zigcina amaqondo obushushu angaguqukiyo ngaphakathi kotshintsho lwe-±1°F. Oku kuchaneka kunciphisa ukonakala kwemveliso ngama-30 ekhulwini. Ukusetyenziswa kwamandla apheleleyo kwesakhiwo kwehla ukusuka kwi-15,555 kWh ukuya kwi-8,500 kWh ngonyaka kwiyunithi eqhelekileyo ye-800-square-foot. Izibane ze-LED ezenzelwe iindawo ezibandayo zongeza i-350 kWh ngonyaka kodwa zihlala ixesha elide kathathu kunezixhobo zesiqhelo. Le ndlela idibeneyo inika imbuyekezo kutyalo-mali kwiminyaka eyi-2.8 ngokunciphisa iindleko zombane kunye nexabiso lempahla egciniweyo.
Amaqela okwakha kufuneka alungelelanise zombini izinto ngexesha lokufakelwa. Iiphaneli zifuna ukubekwa nge-laser ukuqinisekisa ukuba imithungo ayingeni moya. Iipayipi zefriji zifuna ukufakelwa ngaphambi kokuba zidlule kwiindlela zokungena eludongeni. Iiprotokholi zokuqalisa zivavanya yonke inkqubo phantsi kweemeko zomthwalo opheleleyo.
