1. Lub te nyob rau saum npoo ntawm cov neeg ntxeev siab yog cov tuab heev lossis muaj plua plav ntau dhau, thiab cov cua sov hloov pauv tau txo qis
Lwm qhov laj thawj tseem ceeb rau lub qeeb qeeb ntawm qhov kub hloov chaw ua haujlwm ntawm cov plua plav tuab lossis plua tshauv ntau dhau ntawm cov txiv ntoo. Since the surface temperature of the evaporator in the refrigeration cold storage is mostly lower than 0 ℃, and the humidity in the warehouse is relatively high, the moisture in the air is easily frosted or even frozen on the surface of the evaporator, which affects the heat transfer effect of the evaporator. Txhawm rau tiv thaiv cov nplaim hluav taws xob txheej ntawm cov evaporator los ntawm ua tuab heev, nws yuav tsum tau defrosted tsis tu ncua. Ob txoj hauv kev yooj yim yooj yim ntawm cov hau kev no tau qhia hauv qab no: ① tsum nres defrosting. Ntawd yog, nres txoj haujlwm ntawm lub compressor, qhib lub qhov rooj ntawm lub tsev rau khoom, cia qhov kub ntawm lub tsev rau khoom nce, thiab rov pib dua cov tshuab hluav taws xob tom qab txheej txheem nrawm nrawm. ② Rinse cream. Tom qab txav cov khoom tawm ntawm lub tsev rau khoom, ncaj qha yaug lub npoo ntawm evaporator yeeb nkab nrog kais dej nrog lub zog siab kom yaj los yog poob tawm ntawm cov txheej txheem te. Ntxiv nrog rau cov cua sov tsis zoo hloov cov nyhuv ntawm cov plua tshauv yog qhov ua kom muaj kev vam meej dhau ntawm cov plua tshauv vim tias nws tsis tau ntxuav kom ntev.
2. Vim tsis muaj neeg pluag rwb thaiv tsev lossis kev ua tau zoo, cov tub yees txias cia muaj peev xwm loj ntawm lub peev xwm txias
Cov neeg txom nyem thermal rwb thaiv tsev kev ua tau zoo yog vim tsis muaj tuab ntawm cov kav dej thiab cov chaw ua haujlwm thermal thiab cov khoom siv rwb thaiv tsev thermal. Nws yog feem ntau tshwm sim los ntawm kev xaiv tsis raug ntawm cov thermal rwb thaiv tsev txheej thaum tsim qauv lossis cov khoom tsis zoo ntawm cov khoom siv hluav taws xob thaum lub sijhawm kev tsim kho. Ib qho ntxiv, hauv cov txheej txheem ntawm kev tsim kho thiab siv, cov khoom siv hluav taws xob ua tau zoo, ua rau cov thermal rwb thaiv tsev txheej yog damp, deformed, lossis txawm yaig. qeeb. Lwm qhov laj thawj tseem ceeb rau cov kev ua kom txias txias yog qhov kev sib khi tsis zoo yog qhov chaw khaws khoom tsis zoo ntawm lub tsev rau khoom, thiab cua kub ntau dua huab cua rau hauv cov av nplaum los ntawm kev xau ntawm lub pas dej. Feem ntau, yog tias muaj hws ntawm txoj hlua khi ntawm cov chaw ntim khoom lossis cov khoom lag luam txias rwb thaiv tsev, nws txhais tau tias kev sib khi tsis nruj. Tsis tas li ntawd, nquag qhib thiab kaw ntawm cov khoom lag luam chaw rau khoom lossis ntau tus neeg nkag mus rau lub chaw tsim khoom ua ke kuj tseem yuav muaj peev xwm ua kom muaj lub zog txias rau hauv lub tsev rau khoom. Zam txhob qhib lub chaw ntim khoom kom ntau li ntau tau los tiv thaiv kom tsis txhob muaj huab cua kub los ntawm kev nkag mus rau lub tsev rau khoom. Ntawm chav kawm, thaum lub tsev rau khoom yog nquag npaj los yog cov khoom loj dhau lawm, thiab feem ntau siv sijhawm ntev dua los ua kom txias rau qhov ntsuas kub.
3.
Kev hloov kho tsis raug lossis thaiv ntawm lub pob hluav taws xob throttle yuav cuam tshuam ncaj qha rau cov tub yees tawm hauv cov evaporator. Thaum lub qhov cub loj dua yog qhib ntau dhau, cov neeg ua haujlwm ntws tau loj heev, thiab qhov ntsuas kub nce ntxiv, thiab ntsuas kub ntawm lub tsev rau khoom yuav qeeb; Nyob rau tib lub sijhawm, thaum lub throttle valve yog qhib me me los yog thaiv, lub tub yees txias ntawm lub system kuj tseem raug txo, thiab ntsuas kub ntawm lub tsev rau khoom yuav tseem qeeb. Feem ntau, nws tuaj yeem txiav txim siab seb puas muaj lub thawv throttle yog tsim nyog los ntawm kev saib cov kev siab lim hiam, cua txias thiab txias ntawm cov yeeb nkab nqus. Lub blockage ntawm lub throttle valve yog ib qho tseem ceeb cuam tshuam rau kev ntws ntawm cov tub yees. Cov laj thawj tseem ceeb rau lub blockage ntawm cov throttle valve yog dej khov thaiv thiab av thaiv. Kev thaiv cov dej khov yog vim qhov tsis txaus siab qhuav ntawm lub tshuab ziab khaub ncaws, thiab lub tub yees muaj noo noo. Thaum nws ntws los ntawm cov throttle valve, qhov ntsuas kub poob qis dua 0 ° hauv lub tub yees khov rau hauv dej khov thiab thaiv cov throttle valve lub qhov; Blocky thaiv yog vim muaj kev sib txuam ntawm ntau cov av ntawm lub lim screen ntawm lub taub ntim ntawm lub thawv loj, cov dej ntws ntawm cov tub yees tsis yog du, uas ua rau txhaws.
4. Kev ua haujlwm ntawm cov tub yees compressor yog tsawg, thiab lub peev xwm cua txias tsis tuaj yeem ua tau raws li cov khoom lag luam uas yuav tsum tau ua
Vim tias lub sijhawm ua haujlwm ntev ntawm cov tub yees compressor, cov tog raj kheej thiab lwm yam kev sib kis tau ua kom muaj zog, thiab cov khoom sib txuas tau txo qis, thiab muaj peev xwm txias yuav txo qis. Thaum lub peev xwm txias txias yog tsawg dua li cov cua sov thauj ntawm lub tsev rau khoom, qhov kub ntawm lub tsev rau khoom yuav poob qeeb. Lub peev xwm ntawm lub compressor tuaj yeem raug txiav txim siab los ntawm kev soj ntsuam lub nqus thiab tshem tawm cov tshuab hluav taws xob ntawm lub compressor. Yog tias lub tub yees muaj peev xwm ntawm lub compressor txo qis, cov qauv siv feem ntau yog los hloov lub tog raj kheej Liner thiab Piston nplhaib ntawm lub compressor. Yog tias kev hloov pauv tseem tsis ua haujlwm, lwm yam yuav tsum tau txiav txim siab, lossis txawm tias dismantling thiab kev hloov pauv, thiab daws teeb meem.
5. Muaj huab cua ntau dua lossis tub yees roj hauv cov evaporator, thiab cov nyhuv hloov cua sov yog txo
Ib zaug ntxiv cov roj hauv tub yees txuas rau sab hauv ntawm cov raj kub hloov pauv ntawm lub tshav kub hloov pauv, nws cov cua sov hloov yuav qis dua. Ib yam li ntawd, yog tias muaj huab cua ntau dua nyob rau hauv lub tshav kub hloov lub raj, lub tshav kub hloov chaw yuav raug txo kom tsawg, thiab nws qhov hloov cua sov yuav raug txo kom tsawg. Kev ua tau zoo yuav kuj poob qis, thiab tus nqi ntawm kev poob qis hauv chaw ua haujlwm kub yuav qeeb. Yog li ntawd, hauv kev ua haujlwm txhua hnub thiab tu cev, kev saib xyuas yuav tsum tau raug tshem tawm cov roj sib tsoo kom zoo dua ntawm cov cua sov txhim kho kev hloov kho cua sov ntawm cov evaporator.
6. Tus nqi ntawm cov tub yees hauv lub system tsis txaus, thiab lub peev xwm txias txias yog qhov tsis txaus
Muaj ob qho laj thawj tseem ceeb rau cov kev taug kev ua tub yees tsis txaus. Ua ntej, lub tub yees lub tub sab tsis txaus. Nyob rau lub sijhawm no, tsuas yog muaj nyiaj txaus ntawm cov tub yees txias uas yuav tsum tau ntxiv. Lwm qhov laj thawj yog tias muaj ntau cov dej khov rau hauv cov kab ke. Hauv qhov no, koj yuav tsum xub pom lub ntsej muag xau, tsom rau kev kuaj xyuas cov kev sib txuas ntawm txhua qhov raj thiab valve, thiab tom qab ntawd sau rau hauv cov chaw so.
