Tus neeg nyob hauv lub tub yees muaj dab tsi? Qhov ncaj tshaj plaws! Tom qab tag nrho, ib chav tsev tau ua hauj lwm hauv lub tropics, lub lwm - nyob rau sab qaum teb sab qaum teb. Muaj zog frosts thiab high temperatures rau cov khoom siv hauv vaj hauv tsev yog txaus ntshai, vim lawv muaj peev xwm lov tes taw nws. Tias yog vim li cas ib qho tseem ceeb qhia xws li chav kawm txias ntawm lub tub yees txias tseem ceeb, thiab nws yuav tsum tau them nyiaj rau nws thaum xaiv koj tus neeg pab hauv tsev.
Kev faib tawm
Txhua lub chaw ua dej num yuav tsum qhia qhov ntsuas no rau ntawm lub tub yees (hauv daim ntawv ntawm daim ntawv nplaum) los yog cov ntaub ntawv uas nrog. Yog hais tias lub chaw, alas, ua tsis tau zoo vim tias koj tau txiav txim siab tsis ncaj ncees rau chav kawm ntawm lub tub yees, ces qhov chaw muab kev pabcuam muaj cai tsis kam lees kev pabcuam.
Tsuas muaj plaub hoob kawm xwb: chav kawm huab cua N, SN, ST thiab T. Cia peb xav txog lawv hauv ntau yam. Nyob rau hauv chav kawm N muaj cov tub yees tsim rau kev khiav hauj lwm hauv tej yam kev mob, uas yog, nyob rau hauv qhov kub li ntawm 16-32 degrees. Nyob rau hauv peb cov latitudes, cov qauv no yog cov xav tau ntau tshaj plaws. Cov chav kawm ntawv SN suav nrog cov aggregates uas yuav ua hauj lwm li niaj zaus nyob rau ntawm ambient temperature ntawm 10 mus rau 32 degree. Yog tias qhov ntsuas kub nyob hauv ib cheeb tsam twg yog qhov hloov ntawm 18-38 degrees thiab qhov av qis dua, koj yuav tsum tau mloog cov tub yees ntawm cov huab cua climatic ST. Rau cov teb chaws kub tshaj plaws, qhov chaw txias tuaj yeem hloov tau los ntawm 18 mus rau 43 degrees, txias ntawm hoob T yuav ua.
Ob peb xyoos dhau los, qee cov chaw lag luam pib tsim cov tub yees uas muaj ob chav kawm:
- N-ST (16-38 degrees);
- NT (16-43 degrees);
- SN-ST (10-38 degrees);
- SN-T (10-43 degrees).
Obviously, cov tub yees ntawm SN-T chav kawm yog qhov ntau yam, vim lawv tuaj yeem ua haujlwm nyob rau hauv qhov kub siab tshaj plaws.
Nws yog tsim nyog sau cia tias chav kawm txias ntawm lub tub yees thiab lub freezer - ib qho qhia tau tias nyob hauv txhua lub teb chaws. Ua ntej muab cov neeg tau txais kev pab tom ntej no, cov chaw tsim tshuaj yuav tsum kuaj lawv nyob rau hauv cov kev mob uas ze li sai tau rau cov neeg qhov khoom siv tom qab siv. Piv txwv, nyob rau hauv Russia txhua daim ntawm cov cuab yeej yuav tsum ua raws li GOSTs. Hauv cov Lavxias So Zaub Mov, SN hoob kawm, thiab N, ntxiv nrog cov ntawv UHL, uas txhais tau hais tias "kev nyab xeeb kub yau". Cov khoom noj hauv tsev tsim rau lub tropics, tab sis manufactured nyob rau hauv Russia, ntxiv rau cim nrog O, uas yog, "general climatic".
Txawv
Tsis txhob xav tias taw tes tawm ob chav kawm, cov tuam txhab tau sim ua rau cov neeg xav tau ntau dua
Yog tias koj txiav txim siab yuav nqus cov tub yees ob chav tub yees, koj yuav tsum to taub tias qhov kev paub ntau no yuav cuam tshuam tus nqi ntawm chav tsev. Tsis tas li ntawd, ua tib zoo xyuas qhov tseeb tias cov cua txias kom ntau dua ntau dua hluav taws xob. Yog vim li no nws thiaj li tsim nyog siv sij hawm me ntsis ntxiv thiaj nrhiav tau hauv cov khoom siv hauv tsev cia qhov zoo ntawm lub tub yees uas txuam nrog koj lub tsev.
