Tsis muaj teeb meem dab tsi ntawm lub tub yees compressor chav tsev, nws tau txiav txim siab raws li qhov kub thiab txias evaporating thiab qhov ua haujlwm zoo ntawm qhov txias cia.
Tsis tas li ntawd, cov kev ntsuas xws li condensation kub, ntim ntim, thiab zaus ntawm cov khoom nkag thiab tawm hauv lub tsev rau khoom yuav tsum raug xa mus rau.
Peb tuaj yeem kwv yees lub peev xwm txias ntawm chav tsev raws li cov qauv hauv qab no:
01), cov qauv rau kev suav cov peev txheej txias txias txias txias yog:
Cov tub yees muaj peev xwm = txias cia ntim × 90 × 1.16 + zoo sib txawv;
Qhov zoo sib txawv yog txiav txim siab raws li qhov ntsuas kub ntawm cov khoom khov lossis cov tub yees, qhov ntim cia, thiab qhov zaus ntawm cov khoom nkag thiab tawm hauv lub tsev rau khoom, thiab qhov ntau ntawm 100-400W.
02), cov mis rau xam qhov txias peev xwm ntawm nruab nrab-kub active txias cia yog:
Cov tub yees muaj peev xwm = txias cia ntim × 95 × 1.16 + zoo sib txawv;
Qhov sib txawv ntawm qhov zoo sib txawv ntawm 200-600W;
03), cov qauv rau kev suav cov peev txheej txias ntawm qhov qis-kub active txias cia yog:
Cov tub yees muaj peev xwm = txias cia ntim × 110 × 1.2 + zoo sib txawv;
Qhov sib txawv ntawm qhov zoo sib txawv ntawm 300-800W.
- 2. Kev xaiv ceev thiab tsim cov tub yees evaporator:
01), tub yees evaporator rau lub freezer
Lub load rau ib lub cubic meter yog xam raws li W0 = 75W / m3;
- Yog tias V (qhov txias cia ntim) <30m3, qhov txias cia nrog lub sijhawm qhib, xws li cov nqaij tshiab, muab cov coefficient A = 1.2;
- yog 30m3
- Yog tias V≥100m3, qhov txias cia nrog lub sijhawm qhib, xws li cov nqaij tshiab, muab cov coefficient A = 1.0;
- Yog tias nws yog ib lub tub yees, muab cov coefficient B = 1.1; qhov kawg xaiv ntawm cov kiv cua txias ntawm qhov txias cia yog W = A * B * W0 (W yog qhov load ntawm lub kiv cua txias);
- Qhov sib txuam ntawm chav tsev tub yees thiab cua txias ntawm qhov chaw txias txias yog xam raws li qhov ntsuas kub ntawm -10 ° C;
02) 、 Cov tub yees evaporator rau fronzon txias cia.
Lub load rau ib lub cubic meter yog xam raws li W0 = 70W / m3;
- Yog tias V (qhov txias cia ntim) <30m3, qhov txias cia nrog lub sijhawm qhib, xws li cov nqaij tshiab, muab cov coefficient A = 1.2;
- yog 30m3
- Yog tias V≥100m3, qhov txias cia nrog lub sijhawm qhib, xws li cov nqaij tshiab, muab cov coefficient A = 1.0;
- Yog tias nws yog ib lub tub yees, muab cov coefficient B = 1.1;
- Qhov kawg txias cia txias kiv cua yog xaiv raws li W = A * B * W0 (W yog lub kiv cua txias load);
- Thaum qhov chaw txias txias thiab lub txee kub tsis tshua muaj sib koom chav tub yees, qhov sib piv ntawm chav tsev thiab lub tshuab cua txias yuav tsum raug xam raws li qhov ntsuas kub ntawm -35 ° C. Thaum lub qhov txias txias tau sib cais los ntawm qhov ntsuas kub qis, qhov sib txuam ntawm chav tsev tub yees thiab cov kiv cua txias ntawm qhov txias cia yog xam raws li qhov ntsuas kub ntawm -30 ° C.
03) Lub tub yees evaporator rau chav ua haujlwm txias cia:
Lub load rau ib lub cubic meter yog xam raws li W0 = 110W / m3:
- Yog tias V (ntau ntawm chav ua haujlwm) <50m3, muab cov coefficient A = 1.1;
- Yog tias V≥50m3, muab cov coefficient A = 1.0;
- Qhov kawg txias cia txias kiv cua yog xaiv raws li W = A * W0 (W yog lub kiv cua txias load);
- Thaum lub chav ua hauj lwm thiab lub nruab nrab kub txee sib koom lub tub yees, qhov sib piv ntawm chav tsev thiab cov cua txias yuav tsum xam raws li qhov kub ntawm evaporating -10 ℃. Thaum cov chav ua haujlwm raug cais tawm ntawm qhov nruab nrab kub txee, qhov sib txuam ntawm chav txias txias thiab kiv cua txias yuav tsum raug xam raws li qhov ntsuas kub ntawm 0 ° C.
Cov kev suav sau saum toj no yog tus nqi siv, qhov kev suav tseeb yog raws li lub thawv txias cia load xam cov lus.
