Malo Osungira Zinthu Zozizira Amathandiza Kukhazikika kwa Msika

Malo osungira oziziraNyumba zosungiramo zinthu zimakhala ndi gawo lalikulu pa unyolo wamakono woperekera zakudya. Zimateteza ubwino wa chakudya, zimakhazikitsa mitengo, komanso zimathandiza malonda a zinthu zomwe zimakhudzidwa ndi kutentha m'madera osiyanasiyana. Kuyambira zipatso zatsopano mpaka mankhwala, zomangamanga zosungiramo zinthu zozizira zimathandiza kuti zinthu zizipezeka komanso zikhale zotetezeka chaka chonse. Pamene njira zogwiritsira ntchito zinthu zikusintha ndipo maukonde oyendetsera zinthu akuchulukirachulukira, kufunikira kwa nyumba zosungiramo zinthu zozizira bwino kukupitirira kukula.

Ntchito Zazikulu ndi Magawo Aukadaulo a Malo Osungira Zinthu Zozizira

Nyumba yosungiramo zinthu zozizira imapangidwa kuti isunge kutentha kolamulidwa komwe kumachepetsa kuwonongeka kwa zamoyo ndi mankhwala. Kutentha kwanthawi zonse kumadalira magulu a zinthu. Malo osungiramo zinthu ozizira nthawi zambiri amagwira ntchito pakati pa 0°C ndi +4°C pa nyama yatsopano, mkaka, ndi ndiwo zamasamba. Malo osungiramo zinthu zozizira nthawi zambiri amakhala ndi −18°C, zomwe zimagwirizana ndi miyezo yapadziko lonse lapansi yotetezera chakudya. Malo osungiramo zinthu zozizira kwambiri zosungiramo nsomba kapena nyama kwa nthawi yayitali amatha kugwira ntchito kuyambira −25°C mpaka −30°C.

Kugwira ntchito kwa kutentha kumakhudza mwachindunji kugwiritsa ntchito mphamvu moyenera. Mapanelo a polyurethane sandwich okhala ndi kutentha kokwanira pafupifupi 0.022 W/m·K amakhalabe muyezo wamakampani. Pa nyumba zosungiramo zinthu zozizira, makulidwe a kutentha nthawi zambiri amakhala pakati pa 120 mm ndi 150 mm. Izi zimathandiza kuchepetsa kutentha ndikuchepetsa nthawi yogwiritsira ntchito compressor. Pansi nthawi zambiri pamakhala zotchingira kutentha kuyambira 80 mm mpaka 120 mm, kuphatikiza ndi zotchinga za nthunzi kuti zisapitirire kuzizira.

Makina oziziritsira ndi omwe amawononga ndalama zambiri. Kugwiritsa ntchito mphamvu nthawi zambiri kumayimira 60% mpaka 70% ya ndalama zonse zosungiramo zinthu zozizira. Makina oziziritsira amakono a ammonia kapena CO₂ amatha kukwaniritsa kuchuluka kwa magwiridwe antchito pakati pa 3.5 ndi 5.0 pansi pa mikhalidwe yabwino. Ma drive osinthasintha pama compressor ndi mafani a evaporator amachepetsanso kugwiritsa ntchito magetsi ndi 15% mpaka 25% poyerekeza ndi makina okhazikika.

Kuchuluka kwa malo osungiramo zinthu kumatanthauza kuti zinthu zikuyenda bwino. Malo osungiramo zinthu ozizira okhala ndi malo okwera nthawi zambiri amafika kutalika komveka bwino kwa mamita 20 mpaka 35. Makina osungiramo zinthu odzipangira okha amalola kuti malo osungiramo zinthu azikhala opitirira ma pallet 0.8 pa mita imodzi. Kugwiritsa ntchito koyima kumeneku kumachepetsa kugwiritsa ntchito nthaka ndikuchepetsa ndalama zomangira pa malo aliwonse a pallet. Pa malo opitilira ma pallet 20,000, makina odzipangira okha amatha kuchepetsa kufunikira kwa antchito ndi oposa 40%.

Kumanga Nyumba Yosungiramo Zinthu Zozizira

Mabodi abwino kwambiri osungiramo zinthu zozizira amatsimikiza momwe ntchito ikuyendera bwino. Mapanelo apamwamba a polyurethane amapereka ma R-values ​​a 28 mpaka 30 okhala ndi makulidwe a mainchesi anayi okha. Kutsika kwa kutentha kumeneku kumachepetsa kulowa kwa kutentha ndi 50 peresenti poyerekeza ndi zipangizo wamba. Kuteteza kogwira mtima kumachepetsa ntchito ya compressor ndi 35 peresenti. Cholumikizira chilichonse cha panelo chimafuna kutsekedwa bwino kuti kuthetse kutsekeka kwa kutentha. Zotchinga za chinyezi zimaletsa kuzizira komwe kumabweretsa nkhungu ndikuwononga magwiridwe antchito. Malo omwe amagwiritsa ntchito mapanelo apamwamba amanena kuti ndalama zamagetsi zimatsika kuchoka pa $12,000 mpaka $7,500 pachaka pa 1,000 sikweya mapazi. Mapanelo amasunga kutentha kuyambira -10°F mpaka 35°F popanda kusinthasintha kwakukulu.

Ubwino wa zida zoziziritsira umayendetsa magwiridwe antchito otsalawo. Ma compressor amakono okhala ndi semi-hermetic amakwaniritsa kuchuluka kwa mphamvu kogwiritsa ntchito mphamvu kwa 3.4 mpaka 11.7 BTU pa watt-ola. Compressor imagwiritsa ntchito 57 peresenti ya mphamvu yonse ya makina. Mafani a evaporator ogwira ntchito bwino amachepetsa kugwiritsa ntchito kwa gawolo kuchoka pa 10 peresenti kufika pa 7 peresenti ya mphamvu yonse. Ma frequency drive osinthasintha amasintha liwiro la injini, kuchepetsa magwiridwe antchito kuchokera pa 100 peresenti yogwira ntchito mpaka 70 peresenti pansi pa katundu wamba. Ma smart defrost controllers amachepetsa kugwira ntchito kwa heater kufika pa 4.2 peresenti ya nthawi yogwira ntchito, ndikusunga 550 kWh pamwezi.

Kugwirizana pakati pa mapanelo apamwamba ndi zida kumabweretsa phindu lophatikizana. Makina ophatikizana amasunga kutentha kofanana mkati mwa ±1°F. Kulondola kumeneku kumachepetsa kuwonongeka kwa zinthu ndi 30 peresenti. Kugwiritsa ntchito mphamvu zonse pamalopo kumatsika kuchoka pa 15,555 kWh kufika pa 8,500 kWh pachaka pa unit yokhazikika ya 800-square-foot. Kuwala kwa LED komwe kumapangidwira malo ozizira kumawonjezera 350 kWh pachaka koma kumatenga nthawi yayitali katatu kuposa zida wamba. Njira yophatikizanayi imapereka phindu pa ndalama mkati mwa zaka 2.8 kudzera mu kuchepetsa ndalama zogwiritsidwa ntchito komanso kusunga mtengo wazinthu.

Magulu omanga ayenera kugwirizanitsa zinthu zonse ziwiri panthawi yokhazikitsa. Ma panel amafunika kuyikidwa motsogozedwa ndi laser kuti atsimikizire kuti mipata yolowera mpweya ndi yotetezeka. Mapaipi oziziritsa amafunika kutetezedwa asanayambe kulowetsa m'makoma. Ma protocol oyambitsa amayesa dongosolo lonselo pansi pa mikhalidwe yonse yodzaza.
