1, vim lub freezer rwb thaiv tsev los yog sealing kev ua tau zoo yog tsis zoo, ua rau lub txias txias
Yog vim li cas vim li cas cov thermal rwb thaiv tsev tsis zoo yog vim cov kav dej, rwb thaiv tsev board thiab lwm yam rwb thaiv tsev txheej thickness tsis txaus, rwb thaiv tsev thiab thermal rwb thaiv tsev nyhuv tsis zoo, nws yog tsuas yog tsim ntawm rwb thaiv tsev txheej thickness yog tsis xaiv zoo los yog kev tsim kho. ntawm cov khoom siv rwb thaiv tsev zoo tsis zoo. Nyob rau hauv tas li ntawd, nyob rau hauv tus txheej txheem ntawm kev tsim kho, cov rwb thaiv tsev cov ntaub ntawv rwb thaiv tsev cov ntaub ntawv noo noo kuj yuav puas, uas ua rau cov rwb thaiv tsev txheej ntawm noo noo, deformation, los yog txawm rotten, nws tshav kub rwb thaiv tsev thiab thermal rwb thaiv tsev muaj peev xwm poob qis, qhov txias poob nce, qhov kub thiab txias poob qeeb qeeb. nqes. Lwm qhov laj thawj tseem ceeb rau qhov txias poob yog qhov ua haujlwm tsis zoo ntawm kev sib khi, muaj cua kub ntau dua los ntawm kev cuam tshuam los ntawm cov dej ntws tawm. Feem ntau, yog hais tias lub sealing sawb nyob rau hauv lub qhov rooj los yog txias txee thaum tshav kub kub rwb thaiv tsev sealing tshwm sim, nws qhia tau hais tias lub foob tsis nruj. Tsis tas li ntawd, nquag qhib thiab kaw lub qhov rooj lossis ntau tus neeg ua ke rau hauv lub tsev khaws khoom, kuj yuav ua rau kom txias poob. Yuav tsum sim kom tsis txhob qhib qhov rooj kom tsis txhob muaj cua kub ntau rau hauv. Ntawm chav kawm, rau hauv cov khoom muag nquag lossis ntau ntau ntawm cov khoom, cov khoom siv hluav taws xob tau nce ntau, kom txias mus rau qhov ntsuas kub uas yuav tsum tau siv sijhawm ntev.
2, evaporator nto Frost yog tuab heev los yog plua plav ntau dhau, cov nyhuv hloov hluav taws xob txo qis ua rau qis qis hauv qhov kub thiab txias yog lwm qhov laj thawj tseem ceeb rau cov evaporator tshav kub hloov pauv tau qis, uas feem ntau yog vim cov evaporator nto Frost txheej. tuab heev los yog hmoov av ntau dhau los ntawm. Vim lub txias txee evaporator saum npoo kub yog feem ntau qis dua 0 ℃, thiab cov av noo kuj siab, cov dej noo nyob rau hauv cov huab cua yog yooj yim heev nyob rau hauv lub evaporator nto te, los yog txawm dej khov, cuam tshuam lub tshav kub hloov ntawm lub evaporator. Txhawm rau tiv thaiv cov evaporator nto Frost txheej yog tuab heev, nws yog qhov yuav tsum tau defrost nws tsis tu ncua.
Nov yog ob txoj hauv kev yooj yim defrosting:
① nres lub tshuab kom yaj Frost. Ntawd yog, nres lub compressor khiav, qhib lub qhov rooj, cia qhov kub thiab txias, yuav tsum tau cia li melted Frost txheej, thiab ces rov pib lub compressor. ② Frost. Tom qab txav cov khoom tawm ntawm lub freezer, ncaj qha nrog qhov kub thiab txias ntawm cov kais dej kom yaug cov evaporator raj nto, kom cov txheej txheej Frost yaj los yog poob. Ntxiv nrog rau qhov tuab tuab yuav ua rau cov evaporator hloov pauv cov nyhuv tsis zoo, lub evaporator nto vim lub sijhawm ntev tsis tu thiab plua plav tsub zuj zuj yog tuab heev, nws cov cua sov hloov pauv yuav txo qis.
3, lub khw muag khoom lub freezer evaporator nyob rau hauv lub xub ntiag ntawm huab cua ntau los yog tub yees roj, tshav kub hloov cov nyhuv txo
Thaum lub evaporator cua sov hloov raj txuas mus rau sab hauv ntawm cov roj khov ntau dua, nws cov coefficient ntawm cov cua sov hloov mus yuav raug txo, tib yam, yog tias muaj cua ntau hauv cov cua kub hloov mus, qhov evaporator tshav kub hloov chaw yog txo, qhov kub hloov pauv. efficiency kuj tseem yuav txo qis, thiab tus nqi ntawm qhov kub thiab txias yog qeeb qeeb. Yog li ntawd, nyob rau hauv kev ua haujlwm niaj hnub thiab kev saib xyuas, yuav tsum tau them sai sai rau kev tshem tawm cov evaporator kom lub sijhawm hloov lub raj ntawm cov roj thiab tso tawm cov huab cua hauv cov evaporator, txhawm rau txhim kho cov cua sov ntawm cov evaporator.
4, throttle valve tsis raug kho los yog clogged, refrigerant flow yog loj los yog me me heev.
Throttle valve tsis raug tswj los yog thaiv, yuav cuam tshuam ncaj qha rau cov tub yees ntws mus rau hauv evaporator. Thaum lub throttle valve qhib loj heev, lub refrigerant flow yog loj, evaporative siab thiab evaporative kub nce, qhov kub thiab txias yuav qeeb; Nyob rau tib lub sijhawm, thaum lub throttle valve qhib me me los yog thaiv, cov tub yees ntws kuj raug txo, qhov system lub tub yees muaj peev xwm txo qis, qhov kub ntawm chav cia yuav ua rau tus nqi poob qis. Feem ntau los ntawm kev soj ntsuam lub evaporation siab, evaporation kub thiab suction yeeb nkab Frost los txiav txim seb lub throttle refrigerant txaus tsim nyog. Throttle blockage yog ib qho tseem ceeb cuam tshuam rau cov tub yees khiav, ua rau lub qhov txhaws txhaws yog qhov laj thawj tseem ceeb rau cov dej khov thiab cov ntsaws ruaj ruaj. Ice plug yog vim qhov ziab ntawm lub tshuab ziab khaub ncaws tsis zoo, lub tub yees muaj dej, ntws los ntawm lub valve, qhov kub thiab txias poob qis dua 0 ℃, cov dej noo hauv cov tub yees rau hauv dej khov thiab thaiv lub qhov throttle; qias neeg plug yog vim lub throttle valve inlet lim mesh ntawm tsub zuj zuj ntawm ib tug loj tus naj npawb ntawm av, refrigerant txaus tsis du, tsim ntawm blockage.
