1, Itafile yoqwalaselo lweyunithi yefriji ye-condenser
Xa kuthelekiswa nendawo yokugcina izinto ezibandayo enkulu, iimfuno zoyilo lwendawo yokugcina izinto ezibandayo encinci zilula kwaye zilula, kwaye ukufanisa iiyunithi kulula kakhulu. Ke ngoko, umthwalo wobushushu wendawo yokugcina izinto ezibandayo encinci ngokubanzi awudingi kuyilwa kwaye ubalwe, kwaye iyunithi ye-condenser yefriji inokufaniswa ngokwengqikelelo yovavanyo.

Nokuba loluphi uhlobo lweyunithi yecompressor yefriji, imiselwa ngokweqondo lobushushu eliphumayo kunye nomthamo osebenzayo wokusebenza kwendawo ebandayo.
Ukongeza, kufuneka kubhekwe nemilinganiselo efana nobushushu bokufuma, ubungakanani bokugcina, kunye nobuninzi beempahla ezingenayo neziphumayo kwindawo yokugcina impahla.
Singaqikelela nje amandla okupholisa eyunithi ngokwendlela elandelayo:
01), ifomula yokubala umthamo wokupholisa kwindawo yokugcina ubushushu obuphezulu yile:
Umthamo wefriji = umthamo wokugcina obandayo × 90 × 1.16 + ukuphambuka okuhle;
Ukuphambuka okuhle kuqinisekiswa ngokweqondo lobushushu bokufuma kwezinto eziqandisiweyo okanye ezifrijini, umthamo wokugcina, kunye nokuphindaphindwa kweempahla ezingenayo neziphumayo kwindawo yokugcina impahla, kwaye uluhlu luphakathi kwe-100-400W.
02), ifomula yokubala umthamo wokupholisa wesitoreji esisebenzayo esiphakathi-ubushushu yile:
Umthamo wefriji = umthamo wokugcina obandayo × 95 × 1.16 + ukuphambuka okuhle;
Uluhlu lokuphambuka okuhle luphakathi kwe-200-600W;
03), ifomula yokubala umthamo wokupholisa wesitoreji esisebenzayo esinobushushu obuphantsi yile:
Umthamo wefriji = umthamo wokugcina obandayo × 110 × 1.2 + ukuphambuka okuhle;
Uluhlu lokuphambuka okuhle luphakathi kwe-300-800W.
- 2. Ukukhetha ngokukhawuleza kunye noyilo lwe-refrigeartion evaporator:
01), Isitshisi sefriji sefriji
Umthwalo ngemitha nganye yetyhubhu ubalwa ngokwe-W0=75W/m3;
- Ukuba i-V (umthamo wokugcina obandayo) < 30m3, indawo yokugcina ebandayo enamaxesha okuvula aqhelekileyo, njengokugcina inyama entsha, phinda-phinda i-coefficient A=1.2;
- Ukuba yi-30m3
- Ukuba i-V≥100m3, indawo yokugcina ebandayo enamaxesha okuvula aqhelekileyo, njengokugcina inyama entsha, phinda-phinda i-coefficient A=1.0;
- Ukuba yifriji enye, phinda-phinda i-coefficient B = 1.1; ukhetho lokugqibela lwefeni yokupholisa kwindawo yokugcina ebandayo yi-W=A*B*W0 (W ngumthwalo wefeni yokupholisa);
- Ukuhambelana phakathi kweyunithi yokukhenkceza kunye ne-air cooler yendawo yokugcina ebandayo kubalwa ngokweqondo lobushushu lokuphuma komphunga eliyi -10 °C;
02）、Isifudumezi sefriji sokugcina izinto ezibandayo.
Umthwalo ngemitha nganye yetyhubhu ubalwa ngokwe-W0=70W/m3;
- Ukuba i-V (umthamo wokugcina obandayo) < 30m3, indawo yokugcina ebandayo enamaxesha okuvula aqhelekileyo, njengokugcina inyama entsha, phinda-phinda i-coefficient A=1.2;
- Ukuba yi-30m3
- Ukuba i-V≥100m3, indawo yokugcina ebandayo enamaxesha okuvula aqhelekileyo, njengokugcina inyama entsha, phinda-phinda i-coefficient A=1.0;
- Ukuba yifriji enye, phinda-phinda i-coefficient B=1.1;
- Ifeni yokupholisa yokugcina indawo yokubanda ikhethwa ngokwe-W=A*B*W0 (W ngumthwalo wefeni yokupholisa);
- Xa indawo yokugcina ebandayo kunye nekhabhathi yobushushu obuphantsi zabelana ngeyunithi yokukhenkcisa, ukulingana kweyunithi kunye ne-air cooler kufuneka kubalwe ngokweqondo lobushushu bokufuma obuyi--35°C. Xa indawo yokugcina ebandayo yahlulwe kwikhabhathi yobushushu obuphantsi, ukulingana kweyunithi yokukhenkcisa kunye nefeni yokupholisa yendawo yokugcina ebandayo kubalwa ngokweqondo lobushushu bokufuma obuyi--30°C.
03）, i-evaporator yefriji yegumbi lokugcina izinto ezibandayo:
Umthwalo ngemitha nganye yetyhubhu ubalwa ngokwe-W0=110W/m3:
- Ukuba u-V (umthamo wegumbi lokucubungula)<50m3, phinda-phinda i-coefficient A=1.1;
- Ukuba i-V≥50m3, phinda-phinda i-coefficient A=1.0;
- Ifeni yokupholisa yokugcina indawo yokubanda ikhethwa ngokwe-W=A*W0 (W ngumthwalo wefeni yokupholisa);
- Xa igumbi lokucubungula kunye nekhabhinethi yobushushu obuphakathi zabelana ngeyunithi yokukhenkcisa, ukulingana kweyunithi kunye ne-air cooler kufuneka kubalwe ngokweqondo lobushushu bokufuma obuyi -10℃. Xa igumbi lokucubungula lahlulwe kwikhabhinethi yobushushu obuphakathi, ukulingana kweyunithi yokugcina ebandayo kunye nefeni yokupholisa kufuneka kubalwe ngokweqondo lobushushu bokufuma obuyi-0 °C.
Ukubala okungentla lixabiso elibhekisayo, ukubala okuchanekileyo kusekelwe kwitheyibhile yokubala umthwalo wokugcina okubandayo.
