Ukubunjwa kokugcinwa okubandayo kwahlulwe ngamacandelo amahlanu: iyunithi yokugcina ebandayo, ibhodi yokugcina ebandayo (kubandakanywa nomnyango wokugcina obandayo), i-evaporator, ibhokisi yokuhambisa, umbhobho wobhedu.
Ukugcinwa okubandayo
1. Masithethe ngebhodi yokugcina ebandayo kuqala:
Ibhodi yokugcina ebandayo yenziwe ngezinto zomaleko zangaphandle kunye nempahla yangaphakathi. Ubukhulu bebhodi yokugcina ebandayo yahlulahlulwe kwiintlobo ezintlanu: 75mm, 100 mm, 120 mm, 150 mm, kunye ne-200mm.
Izinto zomaleko wangaphandle zohlulwe zibe ziindidi ezintathu: ipleyiti yentsimbi enombala, ipleyiti yealuminiyam efakwe i-embossed, ipleyiti yeBaosteel, kunye nepleyiti yensimbi engenasici. Ubunzima bezinto ezingaphandle zoluhlu lwahlula kwi-0.4mm, 0.5mm, njl njl. Uluhlu lwangaphakathi lwenziwe nge-polyurethane foam.
Ibhodi yokugcina ebandayo esetyenziswa ngokuqhelekileyo yi-100 mm, eyenziwe ngepleyiti yentsimbi enombala oshinyeneyo oyi-0.4mm kunye ne-polyurethane foam. Ukuqina kwebhodi yokugcina ebandayo, ingcono impembelelo yokugquma. Ibhodi yokugcina ebandayo ingenziwa ngokwezifiso ngokweemfuno zabathengi.
Zintathu iindidi zeengcango zokugcina ezibandayo: iingcango ezityibilikayo, iingcango ezityibilikayo, kunye neengcango ezimbini. Ubungakanani kunye nobukhulu bomnyango, ibhodi, njl.
2. Iyunithi yokujiya igumbi elibandayo:
Inkqubo yokusebenza yenkqubo yokukhenkceza yegumbi elibandayo yenziwa ngecompressor—> condenser—> itanki yokugcina ulwelo—> filter—> expansion valve—> evaporator.
Kukho iintlobo ezininzi zeecompressors: Copeland (USA), Bitzer (eJamani), Sanyo (Japan), Tecumseh (eFransi), Hitachi (Japan), Daikin (Japan), Panasonic (Japan).
Ngokufanayo, iimpawu zefriji ezongeziweyo kwicompressor nganye zahlukile, kuquka iR12, R22, R134a, R404a, R410a, R600.
Phakathi kwazo, i-R134a, i-R404a, i-R410a, kunye ne-R600 ziifriji ezikhusela indalo. , Amaxabiso oxinzelelo olongeziweyo kwiifriji ezahlukeneyo nazo zahlukile.
1. Umsebenzi we-condenser kukuphelisa ukushisa kwi-compressor.
Ukuba i-condenser ingcolile kakhulu, okanye iyunithi yokugcina ebandayo ifakwe kwindawo enokutshatyalaliswa kokushisa okungahambi kakuhle, kuya kuchaphazela ngokuthe ngqo umphumo wefriji yokugcina ebandayo. Ngoko ke, phantsi kweemeko eziqhelekileyo, i-condenser idinga ukuhlanjululwa kanye emva kweenyanga ezintathu, kwaye iyunithi yokugcina ebandayo kufuneka ifakwe kwindawo epholileyo eyenza ukutshatyalaliswa kobushushu.
2. Umsebenzi wetanki yokugcina ulwelo kukugcina ifriji yolwelo
Xa inkqubo yefriji isebenza, i-compressor iya kucinezela igesi kwi-condenser ukutshabalalisa ubushushu, kwaye i-refrigerant yamanzi kunye ne-gaseous refrigerant iya kuhamba kunye kwi-tube yobhedu. Ngeli xesha, xa kukho ifriji yolwelo oluninzi, ukugqithisa kuya kugcinwa kwitanki yokugcina amanzi. Ukuba ifriji yolwelo efunekayo kwifriji incinci, itanki yokugcina ulwelo iya kuzalisa ngokuzenzekelayo.
3. Umsebenzi wesihluzi kukucoca ukungcola
Isihluzi siya kuhluza i-debris okanye ukungcola okuveliswe yi-compressor kunye ne-tube yobhedu ngexesha lefriji, njengothuli, umswakama, njl. Ukuba akukho sihluzo, ezi nkunkuma ziya kuthintela i-capillary okanye i-valve yokwandisa, okwenza inkqubo ingakwazi ukufaka efrijini. Xa imeko inzima, uxinzelelo oluphantsi luya kuba luxinzelelo olubi, oluya kubangela umonakalo kwi-compressor.
4. Ivalve yokwandisa
Ivalve yokwandisa i-Thermostatic isoloko ifakwe kumnyango we-evaporator, ngoko ibizwa ngokuba ivelufa yokwandisa. Inemisebenzi emibini engundoqo:
①. Uguqulo. Emva kokuba i-high-high-temperature kunye ne-high-pressure-high-pressure liquid refrigerant idlula kumngxuma wokuguqula i-valve yokwandisa, iba ngubushushu obuphantsi kunye noxinzelelo oluphantsi lwe-mist-like hydraulic refrigerant, ukudala iimeko zokunyuka kwefriji.
②. Lawula ukuhamba kwefriji. Isikhenkcisi solwelo esingena kwi-evaporator siyaphuphuma sisuka kulwelo siye kwirhasi emva kokudlula kwi-evaporator, sifunxa ubushushu, kwaye sinciphisa ubushushu kwindawo ebandayo. Ivalve yokwandisa ilawula ukuhamba kwefriji. Ukuba ukuhamba kukhulu kakhulu, i-outlet iqulethe i-refrigerant yolwelo, enokungena kwi-compressor ukuze ibangele ukuqokelela kwamanzi. Ukuba ukuhamba kuncinci, i-evaporation igqitywe kwangaphambili, eya kubangela ifriji enganeleyo ye-compressor.
3. Umphunga
I-evaporator sisixhobo sokutshintsha ubushushu bodidi lodonga. Ubushushu obuphantsi kunye ne-low-pressure liquid refrigerant iyafunxa kwaye ifunxa ubushushu kwelinye icala lodonga lokudlulisa ubushushu lwe-evaporator, ngaloo ndlela ipholisa i-medium kwelinye icala lodonga lokudlulisa ubushushu. Indawo epholileyo idla ngokuba ngamanzi okanye umoya.
Ngoko ke, ii-evaporators zinokwahlulwa zibe ziindidi ezimbini. Ii-evaporators ezipholisa ulwelo kunye neemphunga ezipholisa umoya. Uninzi lwee-evaporator zokugcina ezibandayo zisebenzisa le yokugqibela.
4. Ibhokisi yombane
Ibhokisi yokuhambisa kufuneka ihlawule ingqalelo kwindawo yokufakela. Ngokuqhelekileyo, ibhokisi yokusabalalisa iya kufakwa ecaleni komnyango wokugcina obandayo, ngoko ke umgca wamandla okugcinwa ukubanda udla ngokuxhotyiswa ngeemitha ezi-1-2 ecaleni komnyango wokugcina obandayo.
5. Umbhobho wobhedu
Kufuneka kuqatshelwe apha ukuba ubude bombhobho wobhedu ukusuka kwiyunithi yokugcina ebandayo ukuya kwi-evaporator kufuneka ilawulwe ngaphakathi kweemitha ezili-15. Ukuba umbhobho wobhedu ude kakhulu, uya kuchaphazela umphumo wefriji.
