1, tebulo la kasinthidwe la condenser la firiji
Poyerekeza ndi malo ambiri osungiramo zinthu zozizira, zofunikira pa kapangidwe ka malo osungiramo zinthu zozizira ang'onoang'ono ndizosavuta komanso zosavuta, ndipo kufananiza mayunitsi kumakhala kosavuta. Chifukwa chake, kutentha kwa malo osungiramo zinthu zozizira ang'onoang'ono nthawi zambiri sikuyenera kupangidwa ndikuwerengedwa, ndipo chipangizo chosungiramo zinthu zoziziritsira chimatha kufananizidwa malinga ndi kuyerekezera kwa empirical.

Kaya ndi mtundu wanji wa chipangizo choziziritsira firiji, chimatsimikiziridwa malinga ndi kutentha komwe kumatuluka ndi kuchuluka kogwira ntchito kwa malo osungiramo zinthu ozizira.
Kuphatikiza apo, magawo monga kutentha kwa condensation, kuchuluka kwa malo osungira, ndi kuchuluka kwa katundu wolowa ndi kutuluka m'nyumba yosungiramo katundu ayeneranso kutchulidwa.
Tikhoza kungoyerekeza mphamvu yozizira ya chipangizocho motsatira njira iyi:
01), njira yowerengera mphamvu yoziziritsira ya malo osungiramo zinthu zozizira kwambiri ndi iyi:
Kuchuluka kwa firiji = kuchuluka kwa malo osungiramo ozizira × 90 × 1.16 + kupotoka kwabwino;
Kupatuka kwabwino kumatsimikiziridwa malinga ndi kutentha kwa madzi oundana a zinthu zozizira kapena zozizira, kuchuluka kwa malo osungira, ndi kuchuluka kwa katundu wolowa ndi kutuluka m'nyumba yosungiramo katundu, ndipo kutalika kwake kuli pakati pa 100-400W.
02), njira yowerengera mphamvu yoziziritsira ya malo osungira ozizira apakatikati ndi iyi:
Kuchuluka kwa firiji = kuchuluka kwa malo osungiramo ozizira × 95 × 1.16 + kupotoka kwabwino;
Kusiyanasiyana kwa kupotoka kwabwino kuli pakati pa 200-600W;
03), njira yowerengera mphamvu yoziziritsira ya malo osungira ozizira otsika kutentha ndi iyi:
Kuchuluka kwa firiji = kuchuluka kwa malo osungiramo ozizira × 110 × 1.2 + kupotoka kwabwino;
Kusiyanasiyana kwa kusiyana kwabwino kuli pakati pa 300-800W.
- 2. Kusankha mwachangu ndi kapangidwe ka refrigeartion evaporator:
01), chotenthetsera mufiriji cha firiji
Katundu pa mita imodzi ya kiyubiki amawerengedwa molingana ndi W0=75W/m3;
- Ngati V (voliyumu yosungiramo zinthu zozizira) < 30m3, malo osungiramo zinthu zozizira okhala ndi nthawi yotsegulira pafupipafupi, monga malo osungira nyama yatsopano, chulukitsani coefficient A=1.2;
- Ngati 30m3
- Ngati V≥100m3, malo osungiramo ozizira okhala ndi nthawi yotsegulira pafupipafupi, monga malo osungira nyama yatsopano, chulukitsani coefficient A=1.0;
- Ngati ndi firiji imodzi, chulukitsani coefficient B = 1.1; chisankho chomaliza cha fan yoziziritsira ya cold storage ndi W=A*B*W0 (W ndi katundu wa fan yoziziritsira);
- Kufananiza pakati pa chipinda choziziritsira ndi choziziritsira mpweya cha chipinda chosungiramo zinthu zozizira kumawerengedwa malinga ndi kutentha kwa nthunzi kwa -10 °C;
02）、Refrigeration evaporator yosungiramo zinthu zozizira za fronzon.
Katundu pa mita imodzi ya kiyubiki amawerengedwa molingana ndi W0=70W/m3;
- Ngati V (voliyumu yosungiramo zinthu zozizira) < 30m3, malo osungiramo zinthu zozizira okhala ndi nthawi yotsegulira pafupipafupi, monga malo osungira nyama yatsopano, chulukitsani coefficient A=1.2;
- Ngati 30m3
- Ngati V≥100m3, malo osungiramo ozizira okhala ndi nthawi yotsegulira pafupipafupi, monga malo osungira nyama yatsopano, chulukitsani coefficient A=1.0;
- Ngati ndi firiji imodzi, chulukitsani coefficient B=1.1;
- Fani yomaliza yoziziritsira yosungiramo zinthu zozizira imasankhidwa malinga ndi W=A*B*W0 (W ndiye katundu wa fan yoziziritsira);
- Pamene malo osungiramo zinthu zozizira ndi kabati yotenthetsera pang'ono zikugawana chipinda choziziritsira, kufananiza kwa chipinda ndi choziziritsira mpweya kuyenera kuwerengedwa malinga ndi kutentha kwa nthunzi kwa -35°C. Pamene malo osungiramo zinthu zozizira alekanitsidwa ndi kabati yotenthetsera pang'ono, kufananiza kwa chipinda choziziritsira ndi fani yoziziritsira ya chipinda choziziritsira kumawerengedwa malinga ndi kutentha kwa nthunzi kwa -30°C.
03）, chotenthetsera mufiriji cha chipinda chosungiramo zinthu zozizira:
Katundu pa mita imodzi ya kiyubiki amawerengedwa molingana ndi W0=110W/m3:
- Ngati V (voliyumu ya chipinda chogwirira ntchito) <50m3, chulukitsani coefficient A=1.1;
- Ngati V≥50m3, chulukitsani coefficient A=1.0;
- Fani yomaliza yoziziritsira yosungiramo zinthu zozizira imasankhidwa malinga ndi W=A*W0 (W ndiye katundu wa fan yoziziritsira);
- Pamene chipinda chokonzera ndi kabati yotenthetsera yapakati zikugawana chipinda choziziritsira, kufananiza kwa chipangizocho ndi choziziritsira mpweya kuyenera kuwerengedwa malinga ndi kutentha kwa nthunzi kwa -10℃. Pamene chipinda chokonzeracho chalekanitsidwa ndi kabati yotenthetsera yapakati, kufananiza kwa chipinda chosungiramo chozizira ndi fan yoziziritsira kuyenera kuwerengedwa malinga ndi kutentha kwa nthunzi kwa 0 °C.
Kuwerengera komwe kwatchulidwa pamwambapa ndi mtengo wofotokozera, kuwerengera kwenikweni kumachokera pa tebulo lowerengera katundu wosungidwa mozizira.
