- Kugawa kutentha kosungirako kozizira:
Malo osungiramo zinthu zozizira nthawi zambiri amagawidwa m'mitundu inayi: kutentha kwambiri, kutentha kwapakati ndi kutentha kochepa, kutentha kochepa komanso kutentha kotsika kwambiri.
Zinthu zosiyanasiyana zimafuna kutentha kosiyana.
A. Malo osungiramo zinthu zozizira kwambiri
Malo osungiramo zinthu zozizira kwambiri ndi omwe timatcha malo osungiramo zinthu zozizira. Kusunga kutentha nthawi zambiri kumakhala pafupifupi 0 ° C, ndipo kuziziritsa mpweya ndi fan yoziziritsira.
B. Malo osungira ozizira apakati ndi otsika kutentha
Malo osungiramo zinthu zozizira pa kutentha kwapakati ndi kotsika ndi malo osungiramo zinthu zozizira pa kutentha kwapamwamba, kutentha nthawi zambiri kumakhala mkati mwa -18°C, ndipo amagwiritsidwa ntchito makamaka kusungiramo nyama, madzi ndi zinthu zoyenera kutentha kumeneku.
C, malo osungira ozizira otentha kwambiri
Malo osungiramo zinthu zozizira otentha kwambiri, omwe amadziwikanso kuti malo osungiramo zinthu zozizira, nthawi zambiri kutentha kwa malo osungiramo zinthu kumakhala pafupifupi -20°C ~ -30°C, ndipo kuzizira kwa chakudya kumachitidwa ndi mpweya wozizira kapena zida zapadera zoziziritsira.
D. Malo osungira ozizira kwambiri kutentha kochepa
Malo osungiramo zinthu zozizira kwambiri kutentha kwambiri, ≤-30 °C, amagwiritsidwa ntchito makamaka pa chakudya chozizira mwachangu komanso pazinthu zapadera monga kuyesa mafakitale ndi chithandizo chamankhwala. Poyerekeza ndi zitatu zomwe zili pamwambapa, ntchito zomwe zili pamsika ziyenera kukhala zochepa pang'ono.
2. Kuwerengera mphamvu yosungiramo zinthu zozizira
Werengerani matani a malo osungiramo zinthu zozizira: (kuwerengedwa malinga ndi kapangidwe ka malo osungiramo zinthu zozizira ndi miyezo ya dziko yofunikira ya mphamvu yosungiramo zinthu zozizira):
Kuchuluka kwa mkati mwa chipinda chozizira × kuchuluka kwa kagwiritsidwe ntchito × kulemera kwa chakudya = kuchuluka kwa chakudya chosungiramo chozizira.
Gawo loyamba ndikuwerengera malo enieni omwe alipo komanso osungidwa mufiriji: malo amkati mwafiriji - malo olowera omwe ayenera kuyikidwa pambali mufiriji, malo omwe zipangizo zamkati zimakhala, ndi malo omwe ayenera kusungidwa kuti mpweya uziyenda mkati;
Gawo lachiwiri ndikupeza kulemera kwa zinthu zomwe zingasungidwe pa kiyubiki mita imodzi ya malo malinga ndi gulu la zinthu zomwe zili mumndandanda, ndikuchulukitsa izi kuti mupeze kuchuluka kwa zinthu zomwe zingasungidwe mufiriji;
500～1000 kiyubiki = 0.40;
1001～2000 kiyubiki = 0.50;
2001 ～10000 kiyubiki = 0.55;
10001～15000 kiyubiki = 0.60.
Zindikirani: Malinga ndi zomwe takumana nazo, kuchuluka kwenikweni komwe kungagwiritsidwe ntchito ndi kwakukulu kuposa kuchuluka komwe kumagwiritsidwa ntchito komwe kwafotokozedwa ndi muyezo wa dziko lonse. Mwachitsanzo, kuchuluka kwa kugwiritsa ntchito koyenera kwa dziko lonse kwa ma cubic metres 1000 cubic metres ndi 0.4. Ngati kuyikidwa mwasayansi komanso moyenera, kuchuluka kwenikweni komwe kungagwiritsidwe ntchito nthawi zambiri kumatha kufika 0.5. -0.6.
Kulemera kwa chakudya mufiriji yogwira ntchito:
Nyama yozizira: matani 0.40 akhoza kusungidwa pa kiyubiki mita imodzi;
Nsomba zozizira: matani 0.47 pa kiyubiki mita;
Zipatso ndi ndiwo zamasamba zatsopano: matani 0.23 akhoza kusungidwa pa kiyubiki mita imodzi;
Ayezi wopangidwa ndi makina: matani 0.75 pa kiyubiki mita imodzi;
Khomo la nkhosa lozizira: matani 0.25 akhoza kusungidwa pa kiyubiki mita imodzi;
Nyama yochotsedwa: matani 0.60 pa kiyubiki mita imodzi;
