I-1, itafile yoqwalaselo lweyunithi yefriji yecondenser
Xa kuthelekiswa nokugcinwa okubandayo okukhulu, iimfuno zoyilo zokugcinwa okubandayo ezincinci zilula kwaye zilula, kwaye ukuhambelana kweeyunithi kulula. Ke ngoko, umthwalo wobushushu oqhelekileyo wogcino olubandayo oluqhelekileyo awudingi ukuyilwa kwaye ubalwe, kwaye iyunithi yecondenser yesikhenkcezisi inokudityaniswa ngokoqikelelo lwamandla.

Kungakhathaliseki ukuba yiyiphi iyunithi ye-compressor ye-brand yefriji, inqunywe ngokuhambelana nobushushu obuphuphumayo kunye nomthamo osebenzayo wokugcinwa okubandayo.
Ukongeza, iiparamitha ezinje ngeqondo lobushushu lokuxinana, umthamo wogcino, kunye nokuphindaphindwa kweempahla ezingenayo neziphuma kwindawo yokugcina iimpahla nazo kufuneka zibhekiswe.
Singaqikelela ngokulula umthamo wokupholisa weyunithi ngokwefomula ilandelayo:
01), ifomula yokubala umthamo wokupholisa wogcino oluphezulu lobushushu obuphezulu yile:
Umthamo wefriji = umthamo wokugcina obandayo × 90 × 1.16 + ukutenxa okulungileyo;
Ukuphambuka okulungileyo kunqunywe ngokuhambelana nokushisa kwe-condensation yezinto ezikhenkcezisiweyo okanye ezifakwe efrijini, umthamo wokugcina, kunye nokuphindaphinda kweempahla ezingenayo kunye nokuphuma kwindawo yokugcina impahla, kwaye uluhlu luphakathi kwe-100-400W.
02), ifomula yokubala umthamo wokupholisa wogcino oluphakathi lobushushu obusebenzayo yile:
Umthamo wefriji = umthamo wokugcina obandayo × 95 × 1.16 + ukutenxa okulungileyo;
Uluhlu lokuphambuka okulungileyo luphakathi kwe-200-600W;
03), ifomula yokubala umthamo wokupholisa wogcino olusezantsi lobushushu obusebenzayo yile:
Umthamo wefriji = umthamo wokugcina obandayo × 110 × 1.2 + ukuphambuka okulungileyo;
Uluhlu lokutenxa okulungileyo luphakathi kwe-300-800W.
- 2.Ukhetho olukhawulezayo kunye noyilo lwe-evaporator yefriji:
01), i-evaporator yefriji yefriji
Umthwalo kwi-cubic meter nganye ubalwa ngokwe-W0=75W/m3;
- Ukuba i-V (umthamo wokugcina obandayo) <30m3, ukugcinwa okubandayo kunye namaxesha okuvula rhoqo, njengokugcinwa kwenyama entsha, phinda-phinda i-coefficient A = 1.2;
- Ukuba 30m3
- Ukuba i-V≥100m3, indawo yokugcina ebandayo enamaxesha okuvula rhoqo, njengokugcinwa kwenyama entsha, phinda-phinda i-coefficient A=1.0;
- Ukuba ifriji enye, phinda-phinda i-coefficient B = 1.1; ukhetho lokugqibela lomqhubi wokupholisa wesitoreji esibandayo ngu-W = A * B * W0 (W ngumthwalo we-fan yokupholisa);
- Ukudibanisa phakathi kweyunithi yesikhenkcisi kunye nesipholisi somoya sogcino olubandayo lubalwa ngokweqondo lobushushu eliphumayo le -10 °C;
02)
Umthwalo kwi-cubic meter nganye ubalwa ngokwe-W0=70W/m3;
- Ukuba i-V (umthamo wokugcina obandayo) <30m3, ukugcinwa okubandayo kunye namaxesha okuvula rhoqo, njengokugcinwa kwenyama entsha, phinda-phinda i-coefficient A = 1.2;
- Ukuba 30m3
- Ukuba i-V≥100m3, indawo yokugcina ebandayo enamaxesha okuvula rhoqo, njengokugcinwa kwenyama entsha, phinda-phinda i-coefficient A=1.0;
- Ukuba sisikhenkcisi esinye, phinda-phinda i-coefficient B=1.1;
- Ifeni yokupholisa yokugcina ebandayo yokugcina ikhethwa ngokwe-W=A*B*W0 (W ngumthwalo wokupholisa wefeni);
- Xa ukugcinwa okubandayo kunye nekhabhinethi yobushushu obuphantsi kwabelana ngeyunithi yefriji, ukuhambelana kweyunithi kunye ne-cooler yomoya kuya kubalwa ngokweqondo lokushisa eliphumayo lika -35 ° C. Xa ukugcinwa okubandayo kuhlulwe kwikhabhinethi yobushushu obuphantsi, ukuhambelana kweyunithi yefriji kunye nefeni yokupholisa yokugcina ebandayo ibalwa ngokuhambelana nobushushu obuphumayo obuyi-30 °C.
03) , i-evaporator yefriji yegumbi lokulungisa elibandayo:
Umthwalo ngecubic meter nganye ubalwa ngokwe W0=110W/m3:
- Ukuba V (umthamo wegumbi lokucubungula)<50m3, phinda-phinda i-coefficient A=1.1;
- Ukuba V≥50m3, phinda-phinda i-coefficient A=1.0;
- Ifeni yokupholisa yokugcina ebandayo yokugcina ikhethwa ngokwe-W=A*W0 (W ngumthwalo wokupholisa wefeni);
- Xa igumbi lokucubungula kunye nekhabhathi yobushushu obuphakathi babelana ngeyunithi yefriji, ukuhambelana kweyunithi kunye ne-cooler yomoya kuya kubalwa ngokuhambelana nobushushu obuphumayo be -10 ℃. Xa igumbi lokucubungula lahlulwe kwikhabhathi yobushushu obuphakathi, ukuhambelana kweyunithi yokugcina ebandayo kunye nefeni yokupholisa iya kubalwa ngokobushushu obuphumayo obuyi-0 °C.
Ubalo olungentla luxabiso lokubhekisela, ukubala ngokuthe ngqo kusekelwe kwitheyibhile yokubala yomthwalo wokugcina obandayo.
