Ulwakhiwo lwendawo yokugcina izinto ezibandayo lwahlulwe lwaba ziinxalenye ezintlanu: iyunithi yokugcina izinto ezibandayo, ibhodi yokugcina izinto ezibandayo (kubandakanya ucango lokugcina izinto ezibandayo), i-evaporator, ibhokisi yokusasaza, umbhobho wobhedu.
Indawo yokugcina izinto ezibandayo
1. Masithethe ngebhodi yokugcina izinto ezibandayo kuqala:
Ibhodi yokugcina izinto ezibandayo yenziwe ngezinto ezingaphandle kunye nezinto ezingaphakathi. Ubukhulu bebhodi yokugcina izinto ezibandayo bahlulwe baba ziintlobo ezintlanu: 75mm, 100 mm, 120 mm, 150 mm, kunye ne-200mm.
Izinto zomaleko wangaphandle zahlulwe zibe ziintlobo ezintathu: ipleyiti yentsimbi enemibala, ipleyiti ye-aluminiyam eqingqiweyo, ipleyiti yeBaosteel, kunye nepleyiti yentsimbi engatyiwayo. Ubukhulu bezinto zomaleko wangaphandle bahlulwe baba yi-0.4mm, 0.5mm, njl. Izinto zomaleko wangaphakathi zenziwe nge-polyurethane foam.
Ibhodi yokugcina izinto ezibandayo esetyenziswa rhoqo yi-100 mm, eyenziwe ngepleyiti yentsimbi enemibala engqindilili eyi-0.4mm kunye ne-polyurethane foam. Okukhona ibhodi yokugcina izinto ezibandayo ityebile, kokukhona isiphumo sokukhusela singcono. Ibhodi yokugcina izinto ezibandayo inokwenziwa ngokwezifiso ngokweemfuno zabathengi.
Kukho iintlobo ezintathu zeengcango zokugcina izinto ezibandayo: iingcango ezityibilikayo, iingcango ezityibilikayo, kunye neengcango eziphindwe kabini. Ubungakanani kunye nobukhulu bomnyango, ibhodi, njl. zinokwenziwa ngokwezifiso ngokweemfuno zabathengi.
2. Iyunithi yokufunxa igumbi elibandayo:
Inkqubo yokusebenza kwenkqubo yokufrijisa igumbi elibandayo yenziwa yi-compressor—> condenser—> itanki yokugcina ulwelo—> filter—> expansion valve—> evaporator.
Kukho iintlobo ezininzi zeecompressor: iCopeland (e-USA), iBitzer (eJamani), iSanyo (eJapan), iTecumseh (eFrance), iHitachi (eJapan), iDaikin (eJapan), iPanasonic (eJapan).
Ngokufanayo, iimpawu zeefriji ezongezwe kwicompressor nganye zahlukile, kuquka i-R12, i-R22, i-R134a, i-R404a, i-R410a, i-R600.
Phakathi kwazo, i-R134a, i-R404a, i-R410a, kunye ne-R600 ziifriji ezinobuhlobo nokusingqongileyo. , Amaxabiso oxinzelelo olongezwe kwiifriji ezahlukeneyo nawo ahlukile.
1. Umsebenzi we-condenser kukukhupha ubushushu kwi-compressor.
Ukuba i-condenser ingcolile kakhulu, okanye iyunithi yokugcina izinto ezibandayo ifakwe kwindawo engenako ukucima ubushushu kakuhle, oko kuya kuyichaphazela ngqo impembelelo yokubanda kwindawo yokugcina izinto ezibandayo. Ke ngoko, phantsi kweemeko eziqhelekileyo, i-condenser kufuneka icocwe kanye kwiinyanga ezintathu, kwaye iyunithi yokugcina izinto ezibandayo kufuneka ifakwe kwindawo enomoya ococekileyo olungele ukucima ubushushu.
2. Umsebenzi wetanki yokugcina ulwelo kukugcina ifriji yolwelo
Xa inkqubo yokukhenkcisa isebenza, icompressor iya kuyicinezela igesi iye kwi-condenser ukuze ikhuphe ubushushu, kwaye i-refrigerant engamanzi kunye ne-gaseous refrigerant ziya kuhamba kunye kwityhubhu yobhedu. Ngeli xesha, xa kukho i-refrigerant engamanzi eninzi, intsalela iya kugcinwa kwi-tank yokugcina ulwelo. Ukuba i-refrigerant engamanzi efunekayo kwi-friji incinci, itanki yokugcina ulwelo iya kuyizalisa ngokuzenzekelayo.
3. Umsebenzi wesihluzo kukucoca ukungcola
Isihluzo siza kucoca inkunkuma okanye ukungcola okuveliswa yi-compressor kunye netyhubhu yobhedu ngexesha lokuphola, njengothuli, ukufuma, njl. Ukuba akukho sihluzo, le nkunkuma iya kuvala i-capillary okanye i-expansion valve, okwenza inkqubo ingakwazi ukuphola. Xa imeko imbi kakhulu, uxinzelelo oluphantsi luya kuba luxinzelelo olubi, oluya kubangela umonakalo kwi-compressor.
4. Ivalvu yokwandisa
Ivalvu yokwandisa i-thermostatic idla ngokufakwa emnyango we-evaporator, ngoko ke ibizwa ngokuba yivalvu yokwandisa. Inemisebenzi emibini ephambili:
1. Ukuguqulwa. Emva kokuba i-refrigerant yolwelo olunobushushu obuphezulu noxinzelelo oluphezulu idlule kumngxunya wokuguqulwa kwevalvu yokwandisa, iba yi-hydraulic refrigerant enobushushu obuphantsi noxinzelelo oluphantsi, idala iimeko zokuphuma komphunga kwe-refrigerant.
2. Lawula ukuhamba kwefriji. Ifriji engamanzi engena kwi-evaporator iyaphuma kulwelo iye kwigesi emva kokudlula kwi-evaporator, ifunxe ubushushu, kwaye inciphise ubushushu kwindawo yokugcina ebandayo. Ivalvu yokwandisa ilawula ukuhamba kwefriji. Ukuba ukuhamba kukhulu kakhulu, indawo yokukhupha inefriji engamanzi, enokungena kwi-compressor ukuze ibangele ukuqokelelana kolwelo. Ukuba ukuhamba kuncinci, ukufuma kugqitywe kwangaphambili, okuya kubangela ukungoneli kwefriji ye-compressor.
3. Isitshisi-moya
I-evaporator sisixhobo sokutshintshiselana ngobushushu esifana nodonga. I-refrigerant yolwelo olushushu oluphantsi nolunoxinzelelo oluphantsi iyanyibilika kwaye ifunxe ubushushu kwicala elinye lodonga lokudlulisa ubushushu lwe-evaporator, ngaloo ndlela ipholisa i-medium kwelinye icala lodonga lokudlulisa ubushushu. I-medium epholileyo idla ngokuba ngamanzi okanye umoya.
Ngoko ke, ii-evaporators zingahlulwahlulwa zibe ziindidi ezimbini: ii-evaporators ezipholisa ulwelo kunye nee-evaporators ezipholisa umoya. Uninzi lwee-evaporators zokugcina ubushushu zisebenzisa ezi zilandelayo.
4. Ibhokisi yombane
Ibhokisi yokuhambisa kufuneka inike ingqalelo kwindawo yokufakela. Ngokubanzi, ibhokisi yokuhambisa iza kufakwa ecaleni komnyango wokugcina izinto ezibandayo, ngoko ke umgca wamandla wokugcina izinto ezibandayo uhlala uxhotyiswe ngemitha eli-1-2 ecaleni komnyango wokugcina izinto ezibandayo.
5. Umbhobho wobhedu
Kufuneka kuqatshelwe apha ukuba ubude bombhobho wobhedu ukusuka kwindawo yokugcina izinto ezibandayo ukuya kwi-evaporator kufuneka bulawulwe ngaphakathi kweemitha ezili-15. Ukuba umbhobho wobhedu mde kakhulu, uya kuchaphazela isiphumo sokukhenkceza.
