1, Refrigeration condenser unit kasinthidwe tebulo
Poyerekeza ndi kusungirako kwakukulu kozizira, zofunikira zopangira zosungirako zozizira zazing'ono zimakhala zosavuta komanso zosavuta, ndipo kufanana kwa mayunitsi kumakhala kosavuta. Chifukwa chake, kutentha kwa malo osungirako ozizira pang'ono nthawi zambiri sikuyenera kupangidwa ndikuwerengedwa, ndipo gawo la condenser la firiji limatha kufananizidwa molingana ndi kuyerekezera kwamphamvu.

Ziribe kanthu mtundu wa refrigeration kompresa unit, izo anatsimikiza malinga evaporating kutentha ndi ogwira ntchito buku la ozizira yosungirako.
Kuphatikiza apo, magawo monga kutentha kwa condensation, kuchuluka kosungirako, komanso kuchuluka kwa zinthu zomwe zimalowa ndikutuluka m'nyumba yosungiramo katundu ziyeneranso kutchulidwa.
Titha kungoyerekeza kuziziritsa kwa unit molingana ndi njira iyi:
01), chilinganizo chowerengera kuchuluka kwa kuziziritsa kosungirako kutentha kwambiri ndi:
Mphamvu ya refrigeration = voliyumu yosungirako kuzizira × 90 × 1.16 + kupotoka kwabwino;
Kupatuka kwabwino kumatsimikiziridwa molingana ndi kutentha kwa condensation kwa zinthu zachisanu kapena mufiriji, voliyumu yosungira, komanso kuchuluka kwa zinthu zomwe zimalowa ndikutuluka m'nyumba yosungiramo zinthu, ndipo kuchuluka kwake kuli pakati pa 100-400W.
02), chilinganizo chowerengera kuchuluka kwa kuziziritsa kwapakati-kutentha kozizira kosungirako ndi:
Mphamvu ya refrigeration = voliyumu yosungirako kuzizira × 95 × 1.16 + kupotoka kwabwino;
Kusiyanasiyana kwapatuka kwabwino kuli pakati pa 200-600W;
03), chilinganizo chowerengera kuchuluka kwa kuziziritsa kwa chosungira chozizira chotsika ndi:
Refrigeration mphamvu = voliyumu yosungirako kuzizira × 110 × 1.2 + kupotoka kwabwino;
Kusiyanasiyana kwapatuka kwabwino kuli pakati pa 300-800W.
- 2.Kusankha mwachangu ndi kapangidwe ka evaporator ya refrigeartion:
01), refrigeration evaporator ya mufiriji
Katundu pa kiyubiki mita amawerengedwa molingana ndi W0=75W/m3;
- Ngati V (voliyumu yosungirako ozizira) <30m3, kusungirako kuzizira komwe kumakhala ndi nthawi zotsegula pafupipafupi, monga kusungirako nyama yatsopano, kuchulukitsa koyeneti A=1.2;
- Ngati 30m3
- Ngati V≥100m3, kusungirako kuzizira komwe kumakhala ndi nthawi zotsegula pafupipafupi, monga kusungirako nyama mwatsopano, kuchulukitsa coefficient A = 1.0;
- Ngati ndi firiji imodzi, chulukitsani coefficient B = 1.1; kusankha komaliza kwa kuzizira kozizira kosungirako kuzizira ndi W = A * B * W0 (W ndi katundu wa fan ozizira);
- Kufananiza pakati pa firiji ndi choziziritsa mpweya chosungirako kuzizira kumawerengedwa molingana ndi kutentha kwa -10 °C;
02), refrigeration evaporator kwa fronzon ozizira yosungirako.
Katundu pa kiyubiki mita amawerengedwa molingana ndi W0=70W/m3;
- Ngati V (voliyumu yosungirako ozizira) <30m3, kusungirako kuzizira komwe kumakhala ndi nthawi zotsegula pafupipafupi, monga kusungirako nyama yatsopano, kuchulukitsa koyeneti A=1.2;
- Ngati 30m3
- Ngati V≥100m3, kusungirako kuzizira komwe kumakhala ndi nthawi zotsegula pafupipafupi, monga kusungirako nyama mwatsopano, kuchulukitsa coefficient A = 1.0;
- Ngati ndi firiji imodzi, chulukitsani coefficient B=1.1;
- Chozizira chozizira chozizira chozizira chimasankhidwa molingana ndi W = A * B * W0 (W ndi katundu wozizira wozizira);
- Pamene chosungira chozizira ndi kabati yotentha yotsika imagawana gawo la firiji, kufanana kwa unit ndi mpweya wozizira kumawerengedwa molingana ndi kutentha kwa -35 ° C. Pamene kusungirako kuzizira kumasiyanitsidwa ndi kabati yotsika kutentha, kufanana kwa firiji ndi chowotcha chozizira chosungirako kuzizira kumawerengedwa molingana ndi kutentha kwa -30 ° C.
03）、 refrigeration evaporator kwa chipinda chosungiramo chozizira:
Katundu pa kiyubiki mita amawerengedwa molingana ndi W0=110W/m3:
- Ngati V (kuchuluka kwa chipinda chopangira)<50m3, chulukitsani coefficient A=1.1;
- Ngati V≥50m3, chulukitsani coefficient A=1.0;
- Chozizira chozizira chozizira chozizira chimasankhidwa molingana ndi W = A * W0 (W ndi katundu wozizira wozizira);
- Pamene chipinda chopangira ntchito ndi kabati ya kutentha kwapang'onopang'ono igawana firiji, kufanana kwa unit ndi mpweya wozizira kumawerengedwa molingana ndi kutentha kwa -10 ℃. Pamene chipinda chopangira ntchito chisiyanitsidwa ndi kabati ya kutentha kwapakati, kufanana kwa chipinda chosungiramo kuzizira ndi chowotcha chozizira chiyenera kuwerengedwa molingana ndi kutentha kwa 0 ° C.
Mawerengedwe omwe ali pamwambawa ndi amtengo wapatali, kuwerengera kwenikweni kumachokera pa tebulo lowerengera katundu wozizira.
