Indawo yokugcina ebandayoIzindawo zokugcina impahla zidlala indima ebalulekile ezindleleni zokuhlinzeka zanamuhla. Zivikela ikhwalithi yokudla, ziqinise amanani, futhi zisekela ukuhweba kwezifunda ngezimpahla ezizwela amazinga okushisa. Kusukela emikhiqizweni emisha kuya kwezemithi, ingqalasizinda yokugcina izinto ezibandayo ivumela ukutholakala nokuphepha unyaka wonke. Njengoba amaphethini okusetshenziswa ethuthuka futhi amanethiwekhi okuhambisa impahla ekhula, isidingo sezindawo zokugcina izinto ezibandayo ezisebenzayo siyaqhubeka nokukhula.
Imisebenzi Eyinhloko kanye Nezimo Zobuchwepheshe Zezindawo Zokugcina Izinto Ezibandayo
Indawo yokugcina izinto ebandayo yenzelwe ukugcina amazinga okushisa alawulwayo anciphisa ukuwohloka kwezinto eziphilayo kanye namakhemikhali. Amazinga okushisa ajwayelekile okusebenza ancike ezinhlotsheni zomkhiqizo. Indawo yokugcina izinto ebandayo ivame ukusebenza phakathi kuka-0°C no-+4°C enyameni entsha, ubisi, kanye nemifino. Indawo yokugcina izinto eqandisiwe ivame ukugcina u-−18°C, okuhambisana nezindinganiso zokuphepha kokudla zomhlaba wonke. Izindawo zokugcina izinto eziqandisiwe zokugcina ukudla kwasolwandle noma inyama isikhathi eside zingasebenza kusukela ku-−25°C kuya ku-−30°C.
Ukusebenza kokushisa kuthinta ngqo ukusebenza kahle kwamandla. Amaphaneli esandwich e-polyurethane anokushisa okuhambayo okungaba ngu-0.022 W/m·K ahlala eyindinganiso embonini. Ezindaweni zokugcina izinto eziqandisiwe, ubukhulu bokushisa buvame ukusuka ku-120 mm kuya ku-150 mm. Lezi zinhlaka zisiza ukunciphisa ukukhuphuka kokushisa nokunciphisa isikhathi sokusebenza kwe-compressor. Izitezi zivame ukufaka izendlalelo zokushisa ezingama-80 mm kuya ku-120 mm, ezihlanganiswe nezithiyo zomusi ukuvimbela ukukhuphuka kweqhwa.
Izinhlelo zokuqandisa zibangela isabelo esikhulu kunazo zonke sezindleko zokusebenza. Ukusetshenziswa kwamandla ngokuvamile kumelela u-60% kuya ku-70% wezindleko zokusebenza zokugcina izinto ezibandayo. Izinhlelo zokuqandisa zesimanje ze-ammonia noma ze-CO₂ zingafinyelela i-coefficient of performance values phakathi kuka-3.5 no-5.0 ngaphansi kwezimo ezilungiselelwe. Ama-variable-frequency drive kuma-compressor kanye nama-evaporator fans anciphisa ukusetshenziswa kukagesi ngo-15% kuya ku-25% uma kuqhathaniswa nezinhlelo zesivinini esinqunyiwe.
Ubuningi besitoreji buchaza ukusebenza kahle kwezomnotho. Izindawo zokugcina izinto ezibandayo ezinendawo ephezulu zivame ukufinyelela ukuphakama okucacile kwamamitha angu-20 kuya kwangu-35. Izinhlelo zokuhlela ama-pallet ezizenzakalelayo zivumela ubuningi bezindawo zokugcina izinto ezingaphezu kwama-pallet angu-0.8 ngemitha yesikwele. Lokhu kusetshenziswa okuqondile kunciphisa ukusetshenziswa komhlaba futhi kunciphisa izindleko zokwakha ngesikhundla se-pallet. Ezindaweni ezidlula izikhundla ze-pallet ezingu-20,000, ukuzenzakalela kunganciphisa isidingo sabasebenzi ngaphezu kwama-40%.
Ukwakhiwa Kwendawo Yokugcina Izinto Ezibandayo
Amabhodi okugcina izinto ezibandayo asezingeni eliphezulu anquma ukusebenza kahle. Amaphaneli e-polyurethane e-premium anikeza amanani e-R angu-28 kuya ku-30 anobukhulu obungamasentimitha amane kuphela. Lokhu kushisa okuphansi kunciphisa ukungena kokushisa ngamaphesenti angu-50 uma kuqhathaniswa nezinto ezijwayelekile. Ukushisa okusebenzayo kunciphisa umthwalo womsebenzi we-compressor ngamaphesenti angu-35. I-joint ngayinye yephaneli idinga ukuvalwa okuphelele ukuze kuqedwe ukubopha okushisa. Izithiyo zomswakama zivimbela ukuminyana okuzala isikhunta futhi kwehlisa ukusebenza. Izakhiwo ezisebenzisa amaphaneli aphezulu zibika ukuthi izindleko zamandla zehla kusuka ku-$12,000 kuya ku-$7,500 minyaka yonke ngamafidi ayizikwele ayi-1,000. Amaphaneli agcina amazinga okushisa asukela ku--10°F kuya ku-35°F ngokushintshashintsha okuncane.
Ikhwalithi yemishini yesiqandisi iqhuba izinguquko zokusebenza ezisele. Ama-compressor esimanje acishe abe yi-hermetic afinyelela izilinganiso zokusebenzisa kahle amandla ezingu-3.4 kuya ku-11.7 BTU nge-watt-hora. I-compressor isebenzisa amaphesenti angu-57 wamandla esistimu ephelele. Abalandeli be-evaporator abasebenza kahle kakhulu banciphisa ukusetshenziswa kwaleso sakhi kusuka kumaphesenti ayi-10 kuya kumaphesenti ayi-7 esamba. Ama-variable frequency drive alungisa isivinini semoto, anciphisa imijikelezo yomsebenzi kusukela ekusebenzeni okungama-100% kuya kumaphesenti angama-70 ngaphansi kwemithwalo ejwayelekile. Abalawuli be-Smart defrost bakhawulela ukusebenza kwe-heater kumaphesenti angu-4.2 esikhathi sokusebenza, onge ama-kWh angu-550 ngenyanga.
Ukusebenzisana phakathi kwamaphaneli aphezulu kanye nemishini kukhiqiza izinzuzo ezihlanganisiwe. Izinhlelo ezihlanganisiwe zigcina amazinga okushisa ahambisanayo ngaphakathi kokushintshashintsha kwe-±1°F. Lokhu kunemba kunciphisa ukubola komkhiqizo ngamaphesenti angu-30. Ukusetshenziswa kwamandla okuphelele kwesakhiwo kwehla kusuka ku-15,555 kWh kuya ku-8,500 kWh minyaka yonke kwiyunithi ejwayelekile engamamitha-skwele angu-800. Ukukhanya kwe-LED okwenzelwe izindawo ezibandayo kunezela ama-kWh angu-350 ngonyaka kodwa kuhlala isikhathi eside ngokuphindwe kathathu kunezinto ezivamile. Indlela ehlanganisiwe iletha imbuyiselo ekutshalweni kwezimali kungakapheli iminyaka engu-2.8 ngokusebenzisa izindleko ezincishisiwe zezinsiza kanye nenani eligcinwe lempahla.
Amaqembu okwakha kumele axhumanise zombili izakhi ngesikhathi sokufakwa. Amaphaneli adinga ukubekwa okuqondiswa yi-laser ukuqinisekisa ukuthi imithungo ayingeni moya. Amapayipi esiqandisini adinga ukufakelwa ngaphambi kokufakwa emanzini odongeni. Amaphrothokholi okusebenza ahlola lonke uhlelo ngaphansi kwezimo zomthwalo ogcwele.
