1, itafula lokucushwa kweyunithi ye-condenser yesiqandisi
Uma kuqhathaniswa nendawo enkulu yokugcina izinto ezibandayo, izidingo zomklamo wendawo encane yokugcina izinto ezibandayo zilula kakhulu, futhi ukufanisa amayunithi kulula kakhulu. Ngakho-ke, umthwalo wokushisa wendawo encane yokugcina izinto ezibandayo ngokuvamile akudingeki uklanywe futhi ubalwe, futhi iyunithi ye-condenser yesiqandisi ingalinganiswa ngokwesilinganiso esibonakalayo.

Kungakhathaliseki ukuthi uhlobo luni lweyunithi ye-compressor yesiqandisi, inqunywa ngokuya ngezinga lokushisa lokuhwamuka kanye nomthamo osebenzayo wesitoreji esibandayo.
Ngaphezu kwalokho, kufanele kubhekwe nemingcele efana nokushisa kokujiya, umthamo wokugcina, kanye nemvamisa yezimpahla ezingenayo neziphumayo endaweni yokugcina impahla.
Singamane silinganisele umthamo wokupholisa weyunithi ngokwefomula elandelayo:
01), ifomula yokubala umthamo wokupholisa wesitoreji esibanda esiphezulu yile:
Umthamo wesiqandisi = ivolumu yokugcina ebanda × 90 × 1.16 + ukuphambuka okuhle;
Ukuphambuka okuhle kunqunywa ngokuya ngokushisa kokujiya kwezinto eziqandisiwe noma eziqandisiwe, umthamo wokugcina, kanye nemvamisa yezimpahla ezingenayo neziphumayo enqolobaneni, futhi ububanzi buphakathi kuka-100-400W.
02), ifomula yokubala umthamo wokupholisa wesitoreji esibandayo esisebenzayo esiphakathi nendawo yile:
Umthamo wesiqandisi = ivolumu yokugcina ebanda × 95 × 1.16 + ukuphambuka okuhle;
Ububanzi bokuphambuka okuhle buphakathi kuka-200-600W;
03), ifomula yokubala umthamo wokupholisa wesitoreji esibandayo esisebenzayo esisezingeni eliphansi yile:
Umthamo wesiqandisi = ivolumu yokugcina ebanda × 110 × 1.2 + ukuphambuka okuhle;
Ububanzi bokuphambuka okuhle buphakathi kuka-300-800W.
- 2. Ukukhetha okusheshayo kanye nomklamo we-refrigeartion evaporator:
01), Isifudumezi sesiqandisi sefriji
Umthwalo ngemitha eyi-cubic ubalwa ngokuya nge-W0=75W/m3;
- Uma u-V (ivolumu yokugcina ebandayo) < 30m3, indawo yokugcina ebandayo enezikhathi zokuvula ezivamile, njengokugcina inyama entsha, phinda i-coefficient A=1.2;
- Uma 30m3
- Uma i-V≥100m3, indawo yokugcina ebandayo enezikhathi zokuvula ezivamile, njengokugcina inyama entsha, phinda i-coefficient A=1.0;
- Uma kuyifriji eyodwa, phinda i-coefficient B = 1.1; ukukhetha kokugcina kwefeni yokupholisa yesitoreji esibandayo yi-W=A*B*W0 (W umthwalo wefeni yokupholisa);
- Ukulingana phakathi kweyunithi yesiqandisi kanye nesipholile somoya sendawo yokugcina ebandayo kubalwa ngokuya ngezinga lokushisa lokuhwamuka elingu--10 °C;
02）、Isiqandisi se-evaporator sokugcina amakhaza e-fronzon.
Umthwalo ngemitha eyi-cubic ubalwa ngokuya nge-W0=70W/m3;
- Uma u-V (ivolumu yokugcina ebandayo) < 30m3, indawo yokugcina ebandayo enezikhathi zokuvula ezivamile, njengokugcina inyama entsha, phinda i-coefficient A=1.2;
- Uma 30m3
- Uma i-V≥100m3, indawo yokugcina ebandayo enezikhathi zokuvula ezivamile, njengokugcina inyama entsha, phinda i-coefficient A=1.0;
- Uma kuyifriji eyodwa, phinda i-coefficient B=1.1;
- Ifeni yokugcina yokupholisa yokugcina ibanda ikhethwa ngokuya nge-W=A*B*W0 (W umthwalo wefeni yokupholisa);
- Uma indawo yokugcina ebandayo kanye nekhabhinethi yokushisa okuphansi kwabelana ngeyunithi yokuqandisa, ukufana kweyunithi kanye ne-air cooler kufanele kubalwe ngokuya ngokushisa kokuhwamuka okungu--35°C. Uma indawo yokugcina ebandayo ihlukaniswe nekhabhinethi yokushisa okuphansi, ukufana kweyunithi yokuqandisa kanye nefeni yokupholisa yesitoreji esibandayo kubalwa ngokuya ngokushisa kokuhwamuka okungu--30°C.
03）, Isiqandisi se-evaporator segumbi lokucubungula indawo yokugcina ebandayo:
Umthwalo ngemitha eyi-cubic ubalwa ngokuya nge-W0=110W/m3:
- Uma u-V (umthamo wegumbi lokucubungula) <50m3, phinda i-coefficient A=1.1;
- Uma u-V≥50m3, phinda i-coefficient A=1.0;
- Ifeni yokugcina yokupholisa yokugcina ikhethwa ngokuya nge-W=A*W0 (W umthwalo wefeni yokupholisa);
- Uma igumbi lokucubungula kanye nekhabhinethi yokushisa okuphakathi nendawo kuhlanganyela iyunithi yesiqandisi, ukufana kweyunithi kanye nesiqandisi somoya kufanele kubalwe ngokuya ngokushisa kokuhwamuka okungu--10℃. Uma igumbi lokucubungula lihlukaniswe nekhabhinethi yokushisa okuphakathi nendawo, ukufana kweyunithi yokugcina ebanda kanye nefeni yokupholisa kufanele kubalwe ngokuya ngokushisa kokuhwamuka okungu-0 °C.
Ukubalwa okungenhla kuyinani elibhekiselayo, ukubalwa okuqondile kusekelwe etafuleni lokubala umthwalo wokugcina okubandayo.
