Ukwakheka kwendawo yokugcina ebandayo kuhlukaniswe izingxenye ezinhlanu: iyunithi yokugcina ebandayo, ibhodi yokugcina ebandayo (kufaka phakathi umnyango wokugcina ebandayo), i-evaporator, ibhokisi lokusabalalisa, ipayipi lethusi.
Indawo yokugcina ebandayo
1. Ake sixoxe ngebhodi lokugcina izinto ezibandayo kuqala:
Ibhodi lokugcina izinto ezibandayo lakhiwe ngezinto ezingaphandle kanye nezinto ezingaphakathi. Ubukhulu bebhodi lokugcina izinto ezibandayo buhlukaniswe ngezinhlobo ezinhlanu: 75mm, 100 mm, 120 mm, 150 mm, kanye no-200mm.
Izinto ezingaphandle zihlukaniswe ngezinhlobo ezintathu: ipuleti lensimbi elinombala, ipuleti le-aluminium eliqoshwe nge-embossed, ipuleti le-Baosteel, kanye nepuleti lensimbi engagqwali. Ubukhulu bezinto ezingaphandle buhlukaniswe ngama-0.4mm, 0.5mm, njll. Izinto ezingaphakathi zenziwe nge-polyurethane foam.
Ibhodi lokugcina izinto ezibandayo elisetshenziswa kakhulu lingu-100 mm, elakhiwe ngepuleti lensimbi elinombala obukhulu obungu-0.4mm kanye ne-polyurethane foam. Uma ibhodi lokugcina izinto ezibandayo lilikhulu, kulapho umphumela wokushisa uba ngcono khona. Ibhodi lokugcina izinto ezibandayo lingenziwa ngokwezifiso ngokwezidingo zamakhasimende.
Kunezinhlobo ezintathu zeminyango yokugcina izinto ezibandayo: iminyango eshelelayo, iminyango eshelelayo, kanye neminyango emibili. Ubukhulu nobukhulu bomnyango, ibhodi, njll. kungenziwa ngezifiso ngokwezidingo zamakhasimende.
2. Iyunithi yokufinyeza igumbi elibandayo:
Inqubo yokusebenza kwesistimu yokuqandisa igumbi elibandayo yakhiwa yi-compressor—> condenser—> ithangi lokugcina uketshezi—> isihlungi—> i-expansion valve—> evaporator.
Kunezinhlobo eziningi zama-compressor: iCopeland (e-USA), iBitzer (eJalimane), iSanyo (eJapane), iTecumseh (eFrance), iHitachi (eJapan), iDaikin (eJapan), iPanasonic (eJapan).
Ngokufanayo, izinhlobo zama-refrigerant afakwe ku-compressor ngayinye zihlukile, kufaka phakathi i-R12, i-R22, i-R134a, i-R404a, i-R410a, i-R600
Phakathi kwazo, i-R134a, i-R404a, i-R410a, kanye ne-R600 ziyiziqandisi ezinobungani nemvelo. , Amanani okucindezela angeziwe eziqandisini ezahlukene nawo ahlukile.
1. Umsebenzi we-condenser ukukhipha ukushisa kwe-compressor.
Uma i-condenser ingcolile kakhulu, noma iyunithi yokugcina ebandayo ifakwe endaweni enokushabalalisa ukushisa okubi, kuzothinta ngqo umphumela wokubanda kwesitoreji. Ngakho-ke, ngaphansi kwezimo ezijwayelekile, i-condenser idinga ukuhlanzwa kanye njalo ezinyangeni ezintathu, futhi iyunithi yokugcina ebandayo kumele ifakwe endaweni enomoya omuhle evumela ukushabalalisa ukushisa.
2. Umsebenzi wethangi lokugcina uketshezi ukugcina isiqandisi esiwuketshezi
Uma uhlelo lokuqandisa lusebenza, i-compressor izocindezela igesi iye ku-condenser ukuze isuse ukushisa, bese i-refrigerant ewuketshezi kanye ne-refrigerant yegesi zizogeleza ndawonye epayipini lethusi. Ngalesi sikhathi, lapho kune-refrigerant ewuketshezi eningi kakhulu, okusele kuzogcinwa ethangini lokugcina uketshezi. Uma i-refrigerant ewuketshezi edingekayo ekuqandiseni incane, ithangi lokugcina uketshezi lizoyigcwalisa ngokuzenzakalelayo.
3. Umsebenzi wesihlungi ukuhlunga ukungcola
Isihlungi sizohlunga ukungcola noma ukungcola okudalwe yi-compressor kanye ne-copper tube ngesikhathi sokushisa, njengothuli, umswakama, njll. Uma kungekho sihlungi, la magciwane azovimba i-capillary noma i-expansion valve, okwenza uhlelo lungakwazi ukupholisa. Uma isimo sibucayi, ukucindezela okuphansi kuzoba ukucindezela okungekuhle, okuzobangela umonakalo ku-compressor.
4. I-valve yokwandisa
I-valve yokwandisa i-thermostatic ivame ukufakwa emnyango we-evaporator, ngakho-ke ibizwa ngokuthi i-valve yokwandisa. Inemisebenzi emibili eyinhloko:
1. Ukuguqulwa. Ngemva kokuba isiqandisi soketshezi esinokushisa okuphezulu kanye nokucindezela okuphezulu sidlule embobeni yokuguqulwa kwevalvu yokunweba, siba isiqandisi se-hydraulic esinokushisa okuphansi kanye nokucindezela okuphansi, okudala izimo zokuhwamuka kwesiqandisi.
②. Lawula ukugeleza kwesiqandisi. Isiqandisi esiwuketshezi esingena ku-evaporator siyahwamuka sisuka kuketshezi siye kugesi ngemva kokudlula ku-evaporator, simunce ukushisa, futhi sinciphise izinga lokushisa endaweni ebandayo yokugcina. I-valve yokwandisa ilawula ukugeleza kwesiqandisi. Uma ukugeleza kukhulu kakhulu, indawo yokukhipha iqukethe isiqandisi esiwuketshezi, esingangena ku-compressor ukuze sibangele ukunqwabelana koketshezi. Uma ukugeleza kuncane, ukuhwamuka kuqedwa kusenesikhathi, okuzobangela ukufriza okunganele kwe-compressor.
3. Isihwamukisi
I-evaporator iyidivayisi yokushintshanisa ukushisa efana nodonga. I-refrigerant yoketshezi olunezinga lokushisa eliphansi kanye nengcindezi ephansi iyahwamuka futhi imunce ukushisa ohlangothini olulodwa lodonga lokudlulisa ukushisa lwe-evaporator, ngaleyo ndlela ipholise i-medium ngakolunye uhlangothi lodonga lokudlulisa ukushisa. I-medium epholile ngokuvamile amanzi noma umoya.
Ngakho-ke, ama-evaporator angahlukaniswa ngezigaba ezimbili. Ama-evaporator apholisa uketshezi kanye nama-evaporator apholisa umoya. Ama-evaporator amaningi okugcina ubanda asebenzisa lawa alandelayo.
4. Ibhokisi likagesi
Ibhokisi lokusabalalisa lidinga ukunaka indawo yokufaka. Ngokuvamile, ibhokisi lokusabalalisa lizofakwa eduze komnyango wokugcina obandayo, ngakho-ke umugqa wamandla wokugcina obandayo uvame ukufakwa amamitha ayi-1-2 eduze komnyango wokugcina obandayo.
5. Ipayipi lethusi
Kufanele kuqashelwe lapha ukuthi ubude bepayipi yethusi kusukela endaweni yokugcina ebandayo kuya ku-evaporator kufanele bulawulwe ngaphakathi kwamamitha ayi-15. Uma ipayipi yethusi lide kakhulu, lizothinta umphumela wokuqandisa.
