Ko da wane nau'in na'urar sanyaya daki, ana ƙayyade shi gwargwadon zafin da ke tururi da kuma ingancin aikin ajiyar sanyi.
Bugu da ƙari, ya kamata a koma ga sigogi kamar zafin danshi, yawan ajiya, da kuma yawan kayan da ke shiga da fita daga cikin rumbun ajiya.
Za mu iya kimanta ƙarfin sanyaya na'urar kawai bisa ga dabarar da ke ƙasa:
01), dabarar da ake amfani da ita wajen ƙididdige ƙarfin sanyaya ajiyar sanyi mai zafi shine:
Ƙarfin sanyaya = girman ajiyar sanyi × 90 × 1.16 + karkacewa mai kyau;
Ana ƙayyade bambancin da ya dace bisa ga zafin danshi na kayan daskararre ko waɗanda aka sanya a cikin firiji, yawan ajiyar kaya, da kuma yawan shigar kaya da barin ma'ajiyar, kuma kewayon yana tsakanin 100-400W.
02), dabarar da ake amfani da ita wajen ƙididdige ƙarfin sanyaya na ajiyar sanyi mai aiki a matsakaicin zafin jiki ita ce:
Ƙarfin sanyaya = girman ajiyar sanyi × 95 × 1.16 + karkacewa mai kyau;
Kewayon karkacewar da aka samu yana tsakanin 200-600W;
03), dabarar da ake amfani da ita wajen ƙididdige ƙarfin sanyaya na ajiyar sanyi mai aiki mai ƙarancin zafin jiki ita ce:
Ƙarfin sanyaya = girman ajiyar sanyi × 110 × 1.2 + karkacewa mai kyau;
Kewayon bambancin da ke tsakanin 300-800W.
- 2. Zaɓi da sauri da ƙirar na'urar fitar da iska ta firiji:
01), Injin fitar da iskar gas na firiji
Ana ƙididdige nauyin da ake buƙata a kowace mita mai siffar sukari bisa ga W0=75W/m3;

- Idan firji ɗaya ne, a ninka adadin B=1.1;
- Ana zaɓar fanka mai sanyaya sanyi ta ƙarshe bisa ga W=A*B*W0 (W shine nauyin fanka mai sanyaya);
- Lokacin da ajiyar sanyi da kabad mai ƙarancin zafin jiki suka raba na'urar sanyaya, za a ƙididdige daidaiton na'urar da mai sanyaya iska bisa ga zafin ƙafewar -35°C. Lokacin da aka raba ajiyar sanyi da kabad mai ƙarancin zafin jiki, ana ƙididdige daidaiton na'urar sanyaya da fanka mai sanyaya na ajiyar sanyi bisa ga zafin ƙafewar -30°C.
03) , Na'urar fitar da iskar sanyi don ɗakin sarrafa ajiya mai sanyi:
Ana ƙididdige nauyin da ake buƙata a kowace mita mai siffar sukari bisa ga W0=110W/m3:
- Idan V (ƙarfin ɗakin sarrafawa) <50m3, ninka ma'aunin A=1.1;
- Idan V≥50m3, ninka ma'aunin A=1.0;
- Ana zaɓar fanka mai sanyaya sanyi ta ƙarshe bisa ga W=A*W0 (W shine nauyin fanka mai sanyaya);
- Lokacin da ɗakin sarrafawa da kabad ɗin matsakaicin zafin jiki suka raba na'urar sanyaya, za a ƙididdige daidaiton na'urar da mai sanyaya iska bisa ga zafin ƙafewar -10℃. Lokacin da aka raba ɗakin sarrafawa da kabad ɗin matsakaicin zafin jiki, za a ƙididdige daidaiton na'urar adana sanyi da fanka mai sanyaya bisa ga zafin ƙafewar 0°C.
Lissafin da ke sama ƙimar tunani ce, ainihin lissafin ya dogara ne akan teburin lissafin nauyin ajiya mai sanyi.
