Ivyuma vy’ibikamyo vy’amafirigo bishirwa ahanini mu migwi A, B, C, D, E, F, G, n’H. Ivyo bice bishingiye ku bushuhe buringaniye buri mu gice c’ibikamyo vy’amafirigo.
1. Ikamyo y'ifiriji yo mu rwego rwa A: Ubushuhe bwo mu nzu buri hagati ya degre 12 na degre 0 . Ivyo bikamyo birabereye ibicuruzwa bikeneye kubikwa muri ubwo bushuhe, nk’imboga zimwezimwe, ivyamwa be n’imiti.
2. Ikamyo y'ifiriji yo mu rwego rwa B: Ubushuhe bwo mu nzu buri hagati ya degre 12 na -10 . Ivyo bikamyo bitanga ubushuhe buke kandi birabereye ibicuruzwa bisaba kubikwa mu bikonje, nk’inyama zimwezimwe be n’ivyo mu kiyaga.
3. Ikamyo y'ifiriji yo mu rwego rwa C: Ubushuhe bwo mu nzu buri hagati ya degre 12 na -20 . Ivyo bikamyo birabereye ku bicuruzwa bisaba gukonja cane, bikaba bituma biguma bikonja mu gihe kirekire bitwarwa.
4. Ivyuma vy’amafirigo vy’umugwi D: Ubushuhe bwo mu nzu ni 0℃canke hasi. Iryo tsinda ry’ibikamyo ryibanda ku kugumiza imizigo ku bushuhe buri munsi ya zero kandi ribereye ibicuruzwa bishobora gushikirwa n’ubushuhe-.
5. Ivyuma vy’amafiriji vy’umugwi E: Ubushuhe bwo mu nzu ni -10 degrees canke hasi. Ivyo bikamyo biratanga uburyo bukomeye bwo kugenzura ubushuhe kandi birabereye ibicuruzwa bisaba kubikwa mu firigo igihe kirekire.
6. Ivyuma vy’amafiriji vy’umugwi F: Ubushuhe bwo mu nzu ni -20℃canke hasi. Uwo mugwi w’ibikamyo urabereye ibicuruzwa bisaba ubushuhe buke cane, nk’ibikoresho bimwebimwe vy’igerageza vy’ubuhinga be n’imiti yihariye.
7. Ivyuma vy'amafiriji vyo mu mugwi G: Ubushuhe bwo mu nzu ni degre 8 gushika kuri degre 2 . Iryo tsinda ry’ibikamyo ryibanda ku kugumiza imizigo mu bushuhe buri hafi y’ubukonje kandi ribereye ibicuruzwa bifise ubushuhe bwihariye busabwa.
8. Ivyuma vy’amafiriji vy’umugwi H: Ubushuhe bwo mu nzu ni -20℃canke hasi. Iryo tsinda ry’ibikamyo ritanga ubushuhe buke cane kandi ribereye ibicuruzwa bisaba gucungera ubushuhe bwinshi cane.
