1, Imbonerahamwe y'ibikoresho byo gukonjesha firigo
Ugereranyije n'ububiko bunini bukonjesha, ibisabwa mu gishushanyo mbonera cy'ububiko buto bukonjesha biroroshye kandi byoroshye, kandi guhuza ibice biroroshye cyane. Kubwibyo, umutwaro w'ubushyuhe bw'ububiko buto bukonjesha muri rusange ubusanzwe ntukenera gutegurwa no kubarwa, kandi icyuma gikonjesha gishobora guhuzwa hakurikijwe isuzuma ry'ubuhanga.

Uko ubwoko bwose bw'icyuma gikonjesha cyaba kiri kose, kigenwa hakurikijwe ubushyuhe buva mu mwuka ndetse n'ingano y'imikorere myiza y'ububiko bukonje.
Byongeye kandi, ibipimo nk'ubushyuhe bwo guhumeka, ingano y'ububiko, n'inshuro ibicuruzwa byinjira n'ibisohoka mu bubiko nabyo bigomba kuvugwaho.
Dushobora gupima ubushobozi bwo gukonjesha bw'igikoresho dukurikije formula ikurikira:
01), formula yo kubara ubushobozi bwo gukonjesha mu bubiko bukonje cyane ni iyi:
Ubushobozi bwo kubika muri firigo = ingano y'ububiko bukonje × 90 × 1.16 + kunyuranya neza;
Itandukaniro ryiza rigenwa hakurikijwe ubushyuhe bw'ibintu bikonje cyangwa bikonjeshejwe, ingano y'ububiko, n'inshuro ibicuruzwa byinjira n'ibisohoka mu bubiko, kandi ingano iri hagati ya 100-400W.
02), formula yo kubara ubushobozi bwo gukonjesha bw'ububiko bukonje buri hagati mu bushyuhe ni:
Ubushobozi bwo kubika muri firigo = ingano y'ububiko bukonje × 95 × 1.16 + kunyuranya neza;
Ingano y'ihindagurika ryiza iri hagati ya 200-600W;
03), formula yo kubara ubushobozi bwo gukonjesha bw'ububiko bukonje bukoresha ubushyuhe buke ni iyi:
Ubushobozi bwo kubika muri firigo = ingano y'ububiko bukonje × 110 × 1.2 + kunyuranya neza;
Ingano y'ihindagurika ryiza iri hagati ya 300-800W.
- 2. Guhitamo no gushushanya byihuse icyuma gikonjesha gikonjesha:
01), icyuma gikonjesha gikonjesha
Umutwaro kuri metero kibe ubarwa hakurikijwe W0=75W/m3;
- Niba V (ingano y'ububiko bukonje) < 30m3, ububiko bukonje bufite amasaha menshi yo gufungura, nko kubika inyama nshya, gwiza igipimo A=1.2;
- Niba 30m3
- Niba V≥100m3, ububiko bukonje bufite amasaha menshi yo gufungura, nko kubika inyama nshya, gwiza igipimo A=1.0;
- Niba ari firigo imwe, gwiza coefficient B = 1.1; amahitamo ya nyuma y'umufana ukonjesha w'ububiko bukonje ni W=A*B*W0 (W ni umutwaro w'umufana ukonjesha);
- Guhuza icyuma gikonjesha n'icyuma gikonjesha cyo mu bubiko bukonjesha bibarwa hakurikijwe ubushyuhe buvamo umwuka bwa -10 °C;
02）、Imashini ishyushya muri firigo yo kubika ibintu bikonje bya fronzon.
Umutwaro kuri metero kibe ubarwa hakurikijwe W0=70W/m3;
- Niba V (ingano y'ububiko bukonje) < 30m3, ububiko bukonje bufite amasaha menshi yo gufungura, nko kubika inyama nshya, gwiza igipimo A=1.2;
- Niba 30m3
- Niba V≥100m3, ububiko bukonje bufite amasaha menshi yo gufungura, nko kubika inyama nshya, gwiza igipimo A=1.0;
- Niba ari firigo imwe, gwiza igipimo B = 1.1;
- Umushyushya wa nyuma wo gukonjesha mu bubiko bukonje utoranywa hakurikijwe W=A*B*W0 (W ni umushyushya w'umushyushya ukonjesha);
- Iyo ububiko bukonje n'akabati k'ubushyuhe buke bisangiye icyuma gikonjesha, ingano y'icyuma gikonjesha n'icyuma gikonjesha bigomba kubarwa hakurikijwe ubushyuhe buvamo umwuka bwa -35°C. Iyo ububiko bukonje butandukanijwe n'akabati k'ubushyuhe buke, ingano y'icyuma gikonjesha n'icyuma gikonjesha cy'icyuma gikonjesha ibarwa hakurikijwe ubushyuhe buvamo umwuka bwa -30°C.
03）, Umushongi ushyushya firigo wo mu cyumba gitunganyirizwamo ibintu bikonje:
Umutwaro kuri metero kibe ubarwa hakurikijwe W0=110W/m3:
- Niba V (ingano y'icyumba cyo gutunganya) <50m3, gwiza igipimo A=1.1;
- Niba V≥50m3, gwiza igipimo A=1.0;
- Umushyushya wa nyuma wo gukonjesha mu bubiko bukonje utoranywa hakurikijwe W=A*W0 (W ni umushyushya w'umushyushya ukonjesha);
- Iyo icyumba gitunganya ibikoresho n'akabati k'ubushyuhe buringaniye bisangiye icyuma gikonjesha, ingano y'icyuma gitunganya ibikoresho n'icyuma gikonjesha bigomba kubarwa hakurikijwe ubushyuhe buvamo umwuka bwa -10°C. Iyo icyumba gitunganya ibikoresho gitandukanye n'akabati k'ubushyuhe buringaniye, ingano y'icyuma gitunganya ibikoresho bikonjesha n'icyuma gikonjesha igomba kubarwa hakurikijwe ubushyuhe buvamo umwuka bwa 0°C.
Ibarura ryavuzwe haruguru ni agaciro k'ikigereranyo, ibarura nyaryo rishingira ku mbonerahamwe y'ibarura ry'umutwaro w'ububiko burimo ibintu bikonje.
