Kutheni le nto amaqondo obushushu obubandayo bokugcina?

Okokuqala, uhlalutyo lokungaphumeleli kunye nonyango lobushushu bokugcina ababandayo awetho

Iqondo lobushushu lefriji liphezulu kakhulu. Emva kovavanyo, iqondo lobushushu leendawo ezimbini zeWereho kuphela yayi-0 ngokuka-0 ° C, kunye neeValloid zoLondolozo lweeValloid zeeWerous ezimbini zavulwa. I-compressor iqalile rhoqo, kodwa imeko ayizange iphucule xa itshintshela kwenye i-compressor, kodwa kukho iqabaka emdaka kumbhobho womoya obuyayo. Emva kokungena kwezi ndawo zimbini, kwafunyaniswa ukuba iqabaka eliqaqambileyo lasekwe kwindawo ekufundeni, kwaye imeko iphucule emva kokuphumelela. Ngeli xesha, ixesha lokuqalisa kunye nobushushu bokugcina i-compressor incitshisiwe, kodwa ayilunganga. Emva koko jonga imida ephezulu nangaphantsi yesenzo soxinzelelo esiphantsi, kwaye wafumanisa ukuba ukungasebenzi kakuhle yi-0.11-5.15npa, oko kukuthi, yinqande i-tcressor xa uxinzelelo luyi-0.15pa. Uluhlu lobushushu obulinganayo lube malunga ne-20 ° C ukuya kwi-18 ° C. Ngokucacileyo, olu seto luphakamile kakhulu kwaye umahluko we-Amplisting mncinci kakhulu. Ke ngoko, lungisa imida ephezulu nengaphantsi yomlawuli ophantsi woxinzelelo. Ixabiso elihlengahlengisiweyo yi-0.05-0.12222Mpa, kunye noluhlu lobushushu olinganayo olinganayo limalunga ne-20 ° C-18 ° C. Emva koko, qalisa inkqubo kwaye uqalise ukusebenza okuqhelekileyo.

2. Izizathu ezininzi zokuqalisa rhoqo iingcali zefriji

I-Crafressors iqala kwaye igqitywe ngumbane ophezulu kwaye ophantsi idluliselwa, kodwa emva kokuya kuhambo oluphezulu, kufuneka lwenziwe i-voltage ephezulu, kufuneka iphinde yenziwe kwakhona ukuba iqale kwakhona i-compressor. Ke ngoko, ukuqalisa rhoqo kunye nokuyeka i-compressor ayibangelwanga yi-voltage ephezulu ngokuhambelana nayo, kodwa ikakhulu yi-voltage ephantsi idlulisele:

1. Umahluko weqondo lobushushu phakathi kwe-ampley kunye ne-voltage ephantsi kakhulu incinci kakhulu, okanye umahluko wamaqondo obushushu phakathi kwe-ampley engaphezulu kwaye i-voltage ephantsi idlulisele incinci kakhulu;

I-2. Ukunyanzelwa kunye nevalve engapheliyo okanye ivalve yokhuseleko ye-compressors, emva koko emva kokuvalwa, irhasi ephezulu iya kuvuza kwinkqubo yoxinzelelo oluphantsi, kwaye uxinzelelo luya kuphakama ngokukhawuleza ukuqala i-compressor. Emva kokuqala, uxinzelelo lwenkqubo ye-voltage ephantsi ihla ngokukhawuleza, i-voltage ephantsi isebenza, kwaye i-compressor iyema;

I-3. I-valve yokubuyisela ioyile ezenzekelayo ye-oyile ye-oyile ye-oyile;

I-4. Ukukhula kweplagi iplagi.

I-3. I-compressor ibaleka ixesha elide

Unobangela wexesha elide lokubaleka kwe-compressoor yeyona nto ingonelanga yeyunithi okanye umthwalo wobushushu ogqithisileyo wesitoreni esibandayo, ikakhulu kubandakanya:

1. I-Evaporator ine-rost enkulu okanye yokugcina ioyile kakhulu;

2. Ukusasazwa kwefriji kule nkqubo akonelanga, okanye i-pipend yohlanga ayigudileyo ngokwaneleyo;

3. Ngenxa yokuphumeza kwe-vetroc kunye neepleyiti zokuphelisa, ukuvuza okukhulu kwe-piston okanye ukusilela kwe-certon ye-piston okanye ukusilela kwe-compressor yokwandisa umthwalo, eyona ndlela yokuhambisa irhasi incitshisiwe.

I-4. I-Criserfar yokuHlala-bushushu yogcino iyonakalisiwe, umnyango awuvalwanga ngokuqinileyo okanye inani elikhulu lezinto ezishushu zikhutshiwe, zikhokelela ekugcinweni komthwalo omkhulu;

5. Iqondo lobushushu lidluliselele, i-voltage ephantsi idlulisela ivalve okanye i-boleloid ye-boleloid kunye nezinye izinto zolawulo zinemposiso, zibangela ukuba amaqondo obushushu afikelela kumda ophantsi. Kodwa i-compressor ayinakuyeka ngexesha.

4. Emva kokuba i-compressor iyayeka, uxinzelelo oluphezulu nolusezantsi lukhawuleza ngokukhawuleza

Oku ikakhulu kungenxa yokuvuza okukhulu okanye ukwaphuka kwe-vestick kunye neepleyiti zokuphelisa i-villa, ukugqobhoza i-gasket phakathi koxinzelelo oluphezulu kunye noxinzelelo oluphantsi lwesilinda, kunye nokungena okukhawulezayo kwe-gesing emva kokuvalwa.

I-5. I-compressor ayinakulayishwa okanye ingalayishwa ngokwesiqhelo

Kwinkqubo yokumiselwa kweMigaqo yamandla elawulwa ngoxinzelelo lweoyile, esona sizathu siphambili yile: Ingcinezelo yeoyile iphantsi kakhulu. . I-Cylinder ye-cylinder i-piston ivuza kakhulu, kwaye isekethe yeoyile ivaliwe; isilinda seoyile sibambekile kwi-piston okanye ezinye iindlela; Ivalve ye-solenoid ayisebenzi ngokwesiqhelo, okanye iron core ine-maynetism yendawo.

I-6. Ukungaphumeleli kwenkqubo

I-1. Ukusuka kwi-Evaporator Coil: Ukusanda kwe-Evaporator Coil akufuneki kube ngaphezulu kwe-3mm. Ukubanda kuninzi kakhulu, ukungaxhathisi i-shirmal kuya kunyuka, kukhokelela kumahluko othile wobushushu obushushu phakathi kwe-elvaporator kunye nokugcinwa kwabantu ababandayo. Ifriji ayinakufumana ubushushu obaneleyo ekuphumezeni kwi-Evaporator. Isixa esikhulu sefrijini efumana ubushushu kumbhobho wokubuya kwaye uphumeza, olonyusa ubuhlungu kumbhobho wokubuya; Ukongeza, i-superhead ivutha yivalve yokwandisa incinci kakhulu okanye i-zero, ibangela ukuba ivale okanye ivale, kwaye i-compressor iya kuyeka uxinzelelo oluphantsi kungekudala. Nangona kunjalo, ivalve ye-solenoid ayivalwanga, kwaye kusekho umthwalo oqinisekileyo wobushushu kwindawo yokubanda. Emva kokuba uxinzelelo lwe-Evaporator luphakama, i-compressor iqala kwakhona, iqala rhoqo. Iqabaka kwi-Evaporator, yona le meko iya kuba. Ngapha koko, iqabaka kwi-Evaporator Coils ye-Eavaratoratoratoral imilambo emibini yobushushu kule nkqubo inzima, ifikelela kwi-1-2cm, echaphazela kakhulu iqondo lokugcina ubushushu kwaye alinakho ukunciphisa ubushushu obushushu. Emva kokungaphumeleli, qhuba inkqubo kwakhona, kwaye iqondo lobushushu lezindlu eziphantsi zeqondo lokugcina amanzi linokuhla ukuya kwi-6-5 ° C.

2. Ixabiso lokumisela lolawulo oluphezulu nolusezantsi aluchanekanga: Ingcali esetyenzisiweyo kwizixhobo zefriji yi-R22, kunye ne-voltage ephezulu yevolda (umda ophezulu) ubukhulu becala i-1.7-1.9MPA. Uxinzelelo (umda osezantsi) we-voltage ephantsi inokuba luhlobo lokugcwalisa ubushushu obuhambelana noyilo -5 ° C (i-cred yeqondo lokusasaza kweqondo lobushushu), kodwa ngokubanzi ingaphantsi koxinzelelo lwe-0.01 MPA. Umahluko wohlengahlengiso lwe-switch ye-voltage ephantsi yi-0.1--0.2MPA. Ngamanye amaxesha isikali sexabiso lokumisela uxinzelelo alichanekanga, kwaye ixabiso lentshukumo ixhomekeke kwixabiso elilinganiswe ngexesha lokulungisa ingxaki. Xa uvavanya umlawuli woxinzelelo olusezantsi, vala kancinci ivalve evaliweyo ye-compressor, kwaye unikele ingqalelo kwixabiso lokubonisa loxinzelelo. Iimpawu ezibonisa ukuba i-compressor iyekisiwe kwaye iqala kwakhona yimida ephezulu nangaphantsi yomlawuli ophantsi. Ukuvavanya umlawuli oxinzelelo oluphezulu, vala kancinci ivalve yokumisa i-compressor, kwaye ufunde ukufundwa kwegesi yokukhupha, kwaye ufunde ukuhlelwa kwe-discrarge xa ​​i-compressor iyayeka, oko kukuthi, uxinzelelo oluphezulu lwengcinezelo. Qinisekisa ukuthembeka koxinzelelo lwemouge ngaphambi kovavanyo; Ukuqinisekisa ukhuseleko, ivalve yokukhupha akufuneki ivalwe ngokupheleleyo.

3. Ukungasebenzi kakuhle kwiNkqubo: Kwisixhobo esinetanki yokugcina amanzi, ngenxa yomsebenzi wohlengahlengiso lwetanki yokugcina i-Lique, ngaphandle kokuba itanki yokugcina i-Lisele, eya kuthi ichaphazele ukusebenza kwesixhobo. "Ingcali yefriji", okt inqanaba eliphantsi le-fluid, aliyi kuba nefuthe elibonakalayo ekusebenzeni kwenkqubo yenkqubo. Nangona kunjalo, kwisixhobo ngaphandle kwetanki yokugcina i-ball, kuba isixa sefriji kule nkqubo simisela inqanaba lefriji, xa lichaphazela olo tshintsho kwinkqubo yokusetyenziswa kwezixhobo:

(1) I-Converessi ihlala isebenza, kodwa iqondo lokushisa lingenakwenziwa;

(2) Ingcinezelo yokuphelisa i-compressor incitshisiwe;

.

.

(5) Inqanaba lolilo le-condenser iphantsi ngokucacileyo.

Xa ukuvulwa kwevalve yolwandiswa i-thermal kulungiswa elincinci kakhulu, uxinzelelo loxinzelelo luya kuncipha, i-Evaporator iya kuncitshiswa kwaye inyibilikisiwe, kwaye inyibilikisiwe. Ke ngoko, xa iqonga lefriji alinakujongwa ngokuchanekileyo. Ukuze ugwebe ukuba ngaba isixa semali yefrijiki kwinkqubo ayonelanga, ezi ndlela zilandelayo zinokusetyenziswa:

Yeka ukusebenzisa ivalve yokwandisa i-thermal, Vula kwaye uhlengahlengise i-valtve yokwandiswa ngokufanelekileyo, kwaye uqaphele le nkqubo ukuze ubone ukuba inokubuyela kwimeko yesiqhelo. Ukuba inokubuyela kwisiqhelo, kuthetha ukuba ivalve yokwandiswa kwe-thermal ayikhange ilungiswe ngokufanelekileyo, kungenjalo kukusilela kwefriji kwinkqubo. Ukuhlaziywa kwefrijiki kwinkqubo (ukuba ayisiyo intlawulo eyoneleyo) ngunobangela wokuvuza. Ke ngoko, emva kokuba igqitywe ukuba le nkqubo ihlaziyiwe ayonelanga, ukuvuza kufuneka kufunyenwe kuqala, kwaye ifriji kufuneka yongezwe emva kokuba ikhutshiwe isuswe.
