A Iimfuno zoyilo lombhobho wokungena
• Ivalve yokhuseleko iya kufakwa kwindawo ethe nkqo ukuya phezulu. Ngaphandle koko, imvume yomenzi kufuneka ifunyanwe.
• Iivalvu zokhuseleko kufuneka zifakwe kufutshane kangangoko nesixhobo okanye inkqubo ekhuselweyo.
• Umbhobho wokungena wokufaka ivalve yokhuseleko kufuneka ibemfutshane kwaye ithe tye. Ubuncinci obunqamlekileyo bombhobho wokungena abuyi kuba ngaphantsi kwendawo enqamlezileyo yokungena kwevalve yokhuseleko. Uxinzelelo oluphezulu kunye nezihlandlo ezinkulu zokufuduka, umbhobho wokungena ekungeneni kufuneka ube mkhulu ngokwaneleyo i-radius ejikelezileyo; Okanye inomjelo ocekethekileyo ekungeneni kuwo indawo enqamlezileyo emalunga nokuphinda kabini indawo yokuphuma enqumlayo.
* Xa i-valve yokunceda ikhutshwe, ukuhla koxinzelelo kwipayipi yokungena, oko kukuthi, phakathi kwezixhobo ezikhuselweyo kunye ne-valve yokunceda, kufuneka ibe yincinci kangangoko kunokwenzeka. AKUKHO IMEKO UXINEZELEKO LUYA KUDLA NGAPHEZU KWE-3% YOXINEZELEKO OKANYE I-1/3 YOMKHULU OMKHULU OVUMELEKILEYO wokuvula/wokuvala umahluko, nokuba yeyiphi na EMNCINANE. Ukuba uxinzelelo lwehla kakhulu, i-valve yokuphumla iya kuxhuma.
• Umbhobho wokungena unikwa ngokubanzi ngesibiyeli seCB

Iivalve eziqhelekileyo kwinkqubo yamanzi yokupholisa umoya iivaluvu eziqhelekileyo kwinkqubo yamanzi yokupholisa umoya yivalve yebhabhathane, ivalve yokukhangela, ivalve yeglowubhu, ivalve yebhola, njl., ukusetyenziswa okuthe ngqo kweyiphi ivalve, kufuneka siqale siqonde inkqubo yamanzi ephakathi. Inkqubo yamanzi yenkqubo yokupholisa umoya esembindini ibandakanya inkqubo yamanzi okupholisa kunye nenkqubo yamanzi abandayo/amanzi ashushu (umbhobho ngokuqhelekileyo omnye, ukujikeleziswa kwamanzi angumkhenkce ehlotyeni kunye namanzi ashushu ebusika). Umoya opholileyo okanye umoya opholileyo kunye nohlobo lwempompo eshushu lubandakanya inkqubo yamanzi efrijini/ashushu kuphela.
Inkqubo yamanzi yokupholisa umoya esetyenziswa ngokuqhelekileyo yivalve yebhabhathane, ivalve yokukhangela, ivalve yeglowubhu, ivalve yebhola, njl., ukusetyenziswa okuthe ngqo kweyiphi ivalve, kufuneka siqale siqonde inkqubo yamanzi yomoya ophakathi.
Inkqubo yamanzi yenkqubo yokupholisa umoya esembindini ibandakanya inkqubo yamanzi okupholisa kunye nenkqubo yamanzi abandayo/amanzi ashushu (umbhobho ngokuqhelekileyo omnye, ukujikeleziswa kwamanzi angumkhenkce ehlotyeni kunye namanzi ashushu ebusika). Umoya opholileyo okanye umoya opholileyo kunye nohlobo lwempompo eshushu lubandakanya inkqubo yamanzi efrijini/ashushu kuphela. Inkqubo yamanzi ejikelezayo yinxalenye ebalulekileyo yenkqubo yomoya ophakathi.
Indawo esembindini ye-air-conditioning iqulunqwe ikakhulu ngamacandelo amathathu: inkqubo yokujikeleza kwamanzi abandayo, inkqubo yokujikeleza kwamanzi okupholisa kunye ne-injini engundoqo:
Inkqubo yokujikeleza kwamanzi abandayo
Le ndawo yenziwe ngempompo ebandayo, ifeni yangaphakathi kunye nombhobho wamanzi abandayo. Ubushushu obuphantsi bamanzi abandayo aphuma kwi-evaporator yomatshini wokusingatha axinzelelwa kumbhobho wamanzi abandayo (amanzi aphumayo) ngempompo yefriji, angene kwigumbi lokutshintshiselana kobushushu, asuse ubushushu egumbini, kwaye abuyele kwi-evaporator. yomatshini wokusingatha (ukubuyisela amanzi). Ifeni yangaphakathi isetyenziselwa ukuvuthela umoya ngombhobho wamanzi abandayo ukunciphisa ubushushu bomoya kunye nokukhawulezisa ukutshintshiselana kobushushu obungaphakathi.
Icandelo lokujikeleza kwamanzi okupholisa
Le nxalenye iqulethwe yimpompo yokupholisa, umbhobho wamanzi okupholisa, inqaba yamanzi okupholisa, njl njl. Inkqubo yokujikeleza kwamanzi epholileyo yokutshintshiselana kobushushu bangaphakathi ngexesha elifanayo, iya kuthatha ubushushu obuninzi bangaphakathi. Amandla obushushu adluliselwa kumanzi okupholisa ngefriji ekwinjini enkulu, ukwenzela ukuba ubushushu bamanzi apholisayo bunyuke. Impompo yokupholisa iya kutshisa uxinzelelo lwamanzi okupholisa kwinqaba yamanzi okupholisa (amanzi), ukuze ikwazi ukutshintshisa ubushushu kunye ne-atmosfera, inciphise ubushushu kwaye ibuyele kwi-condenser ye-injini engundoqo (ukubuyisela amanzi).
Umntu omwakela abantu
Injini ephambili yenziwe ngecompressor, evaporator, condenser kunye nerefrigerant (ifriji). Umjikelo wayo wokusebenza umi ngolu hlobo lulandelayo:
Okokuqala, i-refrigerant ye-gaseous ephantsi yoxinzelelo ixinzelelwe yi-compressor kwi-condenser kwaye iyancipha ngokuthe ngcembe ibe yi-high-pressure liquid. Kwinkqubo ye-condensation, ifriji iya kukhulula amandla amaninzi okushisa, athatyathwa ngamanzi okupholisa kwi-condenser kwaye athunyelwe kwinqaba yokupholisa yangaphandle, kwaye ekugqibeleni ikhutshwe emoyeni. Emva koko xa i-high-high pressure liquid refrigerant kwi-condenser ihamba nge-throttling kunye ne-step-down device phambi kwe-evaporator, i-vaporized ngenxa yokutshintsha ngokukhawuleza koxinzelelo, ukwenza umxube we-gas-liquid kunye nokungena kwi-evaporator. Isikhenkcezisi sisoloko singumphunga kwi-evaporator, kwaye siya kutsala ubushushu bamanzi angumkhenkce ukuze amanzi angumkhenkce afikelele kubushushu obuphantsi. ***, ifriji kwi-evaporator emva kokuba i-gasification ibe yigesi yoxinzelelo oluphantsi, iphinda ingene kwi-compressor, njalo njalo.
Ivalve yokulawula esetyenziswa kwinkqubo yamanzi yomoya yaziwa ngokuba yivalve elawulayo, ikwinkqubo yemibhobho yokulungelelanisa ulwelo okanye isixhobo sokulawula ukuhamba kwegesi. Olu hlengahlengiso lufezwa ngokutshintsha ukuvulwa kweevalvu zokulawula ezidityaniswe kuthotho kwinkqubo yokubhobhoza, ngaloo ndlela itshintsha ukuxhathisa kolwelo.
Ukukhethwa kwevalve yokulawula kubaluleke kakhulu ukuphucula ukuzinza kwenkqubo, ukwandisa ubomi benkonzo yevalve yokulawula kunye nokugcina amandla. Ngaphandle kwedayamitha yevalve eyiyo, inkqubo yokuqukuqela kwamanzi elawulwa ngokuzenzekelayo ayiyi kusebenza kwinqanaba elisebenzayo. Idayamitha yevalve enkulu kakhulu iya kukhokelela ekusebenzeni kakubi kolawulo, inokwenza inkqubo yothuke okanye i-oscillation, kunye nokutyala imali; Incinci kakhulu i-valve ububanzi iya kufuna inkqubo ukuba ibonelele umahluko omkhulu woxinzelelo ukuze kugcinwe ukuhamba okwaneleyo, ukwenzela ukuba umthwalo wempompo ube nzima, ngelixa i-valve isengozini yokulimala, kwaye ayinakunika amandla afunekayo; Bobabini baya kuzisa ukuphazamiseka kokugcinwa kunye nokunciphisa ubomi benkonzo yevalve yokulawula.
Ukususela kwintshayelelo engentla, kunokugqitywa ukuba iivalvu ezisetyenziswa ngokuqhelekileyo kwinkqubo yamanzi yokupholisa umoya zezi: ivalve yebhabhathane yezandla, ivalve yebhabhathane yombane, ivalve yebhabhathane echasene ne-condensation, ivalve yokukhangela ibhabhathane, ivalve yokulawula inqanaba lamanzi, ivalve yokusika, etc. Ukongeza, kwakhona kufuneka irabha uqhagamshelo soft, filter kunye nezinye izincedisi umbhobho.
