1, Ithebula lokucushwa kweyunithi ye-condenser yesiqandisi
Uma kuqhathaniswa nesitoreji esikhulu esibandayo, izidingo zokuklama zesitoreji esincane esibandayo zilula futhi zilula, futhi ukufanisa amayunithi kulula. Ngakho-ke, umthwalo wokushisa ovamile wesitoreji esincane esibandayo ngokuvamile awudingi ukuklanywa nokubalwa, futhi iyunithi ye-condenser yesiqandisi ingafaniswa ngokuvumelana nokulinganisa okunamandla.

Kungakhathaliseki ukuthi yiluphi uhlobo lweyunithi ye-compressor yesiqandisi, kunqunywa ngokusho kwezinga lokushisa elihwamukayo kanye nevolumu yokusebenza ephumelelayo yesitoreji esibandayo.
Ngaphezu kwalokho, amapharamitha afana nezinga lokushisa lokufingqa, umthamo wokugcina, kanye nemvamisa yezimpahla ezingena noma eziphuma endaweni yokugcina impahla kufanele kubhekiswe kukho.
Singamane silinganisele umthamo wokupholisa weyunithi ngokuya ngefomula elandelayo:
01), ifomula yokubala umthamo wokupholisa wesitoreji esibandayo sokushisa okuphezulu ithi:
Umthamo wesiqandisi = umthamo wokugcina obandayo × 90 × 1.16 + ukuphambuka okuhle;
Ukuchezuka okuhle kunqunywa ngokuya ngezinga lokushisa lokufingqa lezinto eziqandisiwe noma eziqandisiwe, umthamo wokugcina, kanye nemvamisa yezimpahla ezingena futhi eziphuma endaweni yokugcina izinto, futhi ububanzi buphakathi kuka-100-400W.
02), ifomula yokubala umthamo wokupholisa wesitoreji esibandayo sezinga lokushisa eliphakathi nendawo ithi:
Umthamo wesiqandisi = umthamo wokugcina obandayo × 95 × 1.16 + ukuphambuka okuhle;
Ibanga lokuchezuka okuhle liphakathi kuka-200-600W;
03), ifomula yokubala umthamo wokupholisa wesitoreji esibandayo esisebenza ngaphansi kwezinga lokushisa eliphansi ithi:
Umthamo wesiqandisi = umthamo wokugcina obandayo × 110 × 1.2 + ukuphambuka okuhle;
Ibanga lokuchezuka okuhle liphakathi kuka-300-800W.
- 2. Ukukhetha okusheshayo kanye nomklamo we-evaporator yesiqandisi:
01), I-evaporator yesiqandisi yesiqandisi
Umthwalo nge-cubic meter ngayinye ubalwa ngokuvumelana ne-W0=75W/m3;
- Uma u-V (umthamo wesitoreji esibandayo) <30m3, indawo yokugcina ebandayo enezikhathi zokuvula njalo, njengokugcina inyama entsha, phindaphinda i-coefficient A=1.2;
- Uma 30m3
- Uma i-V≥100m3, isitoreji esibandayo esinezikhathi zokuvula njalo, njengokugcina inyama entsha, phindaphinda i-coefficient A=1.0;
- Uma kuyisiqandisi esisodwa, phindaphinda i-coefficient B = 1.1; ukukhethwa kokugcina kwefeni yokupholisa yesitoreji esibandayo yi-W=A*B*W0 (W umthwalo wefeni yokupholisa);
- Ukumatanisa phakathi kweyunithi yesiqandisi kanye nesibandisi somoya sesitoreji esibandayo kubalwa ngokwezinga lokushisa elihwamukayo lika -10 °C;
02）, I-evaporator yesiqandisi yokugcina ebandayo ye-fronzon.
Umthwalo we-cubic meter ngayinye ubalwa ngokuvumelana ne-W0=70W/m3;
- Uma u-V (umthamo wesitoreji esibandayo) <30m3, indawo yokugcina ebandayo enezikhathi zokuvula njalo, njengokugcina inyama entsha, phindaphinda i-coefficient A=1.2;
- Uma 30m3
- Uma i-V≥100m3, isitoreji esibandayo esinezikhathi zokuvula njalo, njengokugcina inyama entsha, phindaphinda i-coefficient A=1.0;
- Uma kuyisiqandisi esisodwa, phindaphinda i-coefficient B=1.1;
- Ifeni yokugcina epholile yokugcina ebandayo ikhethwa ngokuvumelana ne-W=A*B*W0 (W umthwalo wefeni yokupholisa);
- Lapho isitoreji esibandayo kanye nekhabethe lokushisa eliphansi kuhlanganyela iyunithi yesiqandisi, ukufanelana kweyunithi nesipholile somoya kufanele kubalwe ngokuvumelana nezinga lokushisa elihwamukayo elingu -35°C. Lapho isitoreji esibandayo sihlukaniswa nekhabhinethi yokushisa ephansi, ukufaniswa kweyunithi yesiqandisi kanye nefeni yokupholisa yesitoreji esibandayo kubalwa ngokuvumelana nezinga lokushisa elihwamukayo lika -30 °C.
03）, I-evaporator yesiqandisi segumbi lokucubungula isitoreji esibandayo:
Umthwalo we-cubic meter ngayinye ubalwa ngokuvumelana ne-W0=110W/m3:
- Uma V (ivolumu yegumbi lokucubungula)<50m3, phindaphinda i-coefficient A=1.1;
- Uma i-V≥50m3, phindaphinda i-coefficient A=1.0;
- Isiphephetha-moya sokupholisa sesitoreji esibandayo sokugcina sikhethwa ngokuya nge-W=A*W0 (W ukupholisa isiphephetha-moya);
- Lapho igumbi lokucubungula kanye nekhabethe lokushisa eliphakathi lihlanganyela iyunithi yesiqandisi, ukufaniswa kweyunithi nesibandisi somoya kufanele kubalwe ngokuvumelana nezinga lokushisa elihwamukayo elingu -10℃. Lapho igumbi lokucubungula lihlukaniswa nekhabethe lokushisa eliphakathi nendawo, ukufanisa iyunithi yokugcina ebandayo kanye nesiphephetha-moya sokupholisa kufanele kubalwe ngokuvumelana nezinga lokushisa elihwamukayo lika-0 °C.
Ukubala okungenhla kuyinani eliyireferensi, ukubala okuqondile kusekelwe kuthebula lokubala lomthwalo wesitoreji esibandayo.
