Ko da wane nau'in nau'in kwampreta na firiji, an ƙaddara shi bisa ga yawan zafin jiki mai ƙafewa da ingantaccen aiki na ajiyar sanyi.
Bugu da kari, ya kamata a yi la'akari da sigogi kamar zafin jiki na tari, ƙarar ajiya, da yawan shigowa da fita sito.
Za mu iya kawai ƙididdige ƙarfin sanyaya na naúrar bisa ga dabara mai zuwa:
01), dabarar ƙididdige ƙarfin sanyaya na ajiyar sanyi mai zafi shine:
Ƙarfin firiji = ƙarar ajiyar sanyi × 90 × 1.16 + tabbataccen karkacewa;
An ƙayyade madaidaicin karkata bisa ga yanayin zafi na daskararru ko abubuwan da aka sanyaya, ƙarar ajiya, da yawan shigowar kaya da barin ɗakin ajiya, kuma kewayon yana tsakanin 100-400W.
02), dabara don ƙididdige ƙarfin sanyaya na ma'ajin sanyi mai matsakaicin zafin jiki shine:
Ƙarfin firiji = ƙarar ajiyar sanyi × 95 × 1.16 + tabbataccen karkacewa;
Matsakaicin madaidaicin karkacewa tsakanin 200-600W;
03), dabara don ƙididdige ƙarfin sanyaya na ma'ajin sanyi mai ƙarancin zafin jiki shine:
Ƙarfin firiji = ƙarar ajiyar sanyi × 110 × 1.2 + tabbataccen karkacewa;
Matsakaicin madaidaicin karkacewa shine tsakanin 300-800W.
- 2.Quick selection da zane na refrigeartion evaporator:
01), Refrigeration evaporator don injin daskarewa
Ana ƙididdige nauyin nauyin mita mai siffar sukari bisa ga W0 = 75W / m3;
- Idan V (ƙarar ajiyar sanyi) <30m3, ajiyar sanyi tare da lokutan buɗewa akai-akai, kamar ajiyar nama sabo, ninka adadin A=1.2;
- idan 30m3
- Idan V≥100m3, ajiyar sanyi tare da lokutan buɗewa akai-akai, kamar ajiyar nama sabo, ninka madaidaicin A=1.0;
- Idan firiji guda ɗaya ne, ninka ma'auni B = 1.1; zaɓi na ƙarshe na mai sanyaya fan na ajiyar sanyi shine W = A * B * W0 (W shine nauyin mai sanyaya);
- An ƙididdige ma'auni tsakanin na'ura mai sanyi da na'urar sanyaya iska na ajiyar sanyi bisa ga yawan zafin jiki na -10 ° C;
02), Refrigeration evaporator for fronzon sanyi ajiya.
Ana ƙididdige nauyin nauyin mita mai siffar sukari bisa ga W0 = 70W / m3;
- Idan V (ƙarar ajiyar sanyi) <30m3, ajiyar sanyi tare da lokutan buɗewa akai-akai, kamar ajiyar nama sabo, ninka adadin A=1.2;
- idan 30m3
- Idan V≥100m3, ajiyar sanyi tare da lokutan buɗewa akai-akai, kamar ajiyar nama sabo, ninka madaidaicin A=1.0;
- Idan firiji guda ɗaya ne, ninka ma'auni B=1.1;
- An zaɓi fan na kwantar da sanyi na ƙarshe bisa ga W = A * B * W0 (W shine nauyin fan mai sanyaya);
- Lokacin da ma'ajiyar sanyi da ma'ajiya mai ƙarancin zafin jiki ke raba naúrar firiji, za a ƙididdige madaidaicin naúrar da na'urar sanyaya iska gwargwadon yanayin ƙafewar -35°C. Lokacin da aka keɓe ma'ajiyar sanyi daga ƙananan ma'ajin zafin jiki, ana ƙididdige ma'auni na naúrar firiji da mai sanyaya fan na ajiyar sanyi bisa ga zafin zafi na -30 ° C.
03) , Refrigeration evaporator don dakin sarrafa sanyi:
Ana ƙididdige kaya a kowace mita mai siffar sukari bisa ga W0 = 110W/m3:
- Idan V (girman dakin sarrafawa) <50m3, ninka madaidaicin A=1.1;
- Idan V≥50m3, ninka coefficient A=1.0;
- An zaɓi fan na sanyi na ƙarshe na ajiyar sanyi bisa ga W = A * W0 (W shine nauyin fan mai sanyaya);
- Lokacin da dakin sarrafawa da ma'aikatun zafin jiki na matsakaici suka raba naúrar refrigeration, madaidaicin naúrar da na'urar sanyaya iska za a ƙididdige shi gwargwadon zafin zafin -10 ℃. Lokacin da dakin sarrafawa ya rabu da ma'aunin zafin jiki na matsakaici, madaidaicin naúrar ajiyar sanyi da fanka mai sanyaya za a ƙididdige shi gwargwadon zafin ƙafe na 0 °C.
Lissafin da ke sama shine ƙimar tunani, ainihin ƙididdiga ya dogara ne akan tebur lissafin nauyin ajiyar sanyi.
