Ukusebenzisa Amachini E-Ayisikondi Emhlabathini Ngokuphakeme: Imiphumela Emikhulu Nokuzinikela
Kubafundisa abaphatha izindawo nezinkulungwane zokuphatha ukuchitha kwezulu, ukusebenza kwesikhumba sokuchitha kwezulu kusukela emhlabathini kuyabhekwa njengokuzimele ngeminyaka yomnyaka. Kepha, lapho isikhati sezulu siphuma, ukusebenza kwezi zikhumba kusukela kusiza kusiza kakhulu. Izikhumba zokuchitha kwezulu zezindawo zisakhiwe ngokuphakeme ukuchitha, futhi ukusebenza kwazo kusiza kusiza lapho isikhati sezulu siphuma ngaphezu kwezinkulungwane ezintathu (60) zezifuzu. Isikhumbu sesibonelo sokuchitha sokushaya isikhumbu sokuchitha kusakhiwe ngokuphakeme ukusebenza kumnyaka omkhulu. Ngemnyaka emhlophe, izihlukaniswa zempilo ezisizakhiwe kusiza kusiza, futhi izinhlelo zokuphatha kusiza kusiza ukuthi izimo eziphuma ziyisibonelo esingasemthethweni. Lokhu kusiza kusiza ukusebenza okuphansi, ukugcinwa kwesikhumba sokuchitha, nokungasebenzi kahle ukuchitha kwezindawo zokufuna ukuchitha ngeminyaka yonke, njengezindawo zokugcina amadatha noma izindawo zokuthuthukisa ukuxhumana, ukuziqonda lezi zinkinga nezinhlelo zokusakha ezinako kusiza kusiza ukuthi ukusebenza kusiza kusiza kumnyaka wemvula.
Izinkinga zokuthermodynamika zokuphuma kwezinsuku ezingenayo umbono
Isiklondi sokugqibela kwe-vapor sokusebenza kwe-air conditioner yasezulwini esingaphansi kuyadizayinwa ukusebenza ngokuhle lapho umoya wendawo yisikhathi esinemilo. Isistimu sivumelwe ukusebenza ngokuthi isikhathi sokugqibela kuyinkulu kakhulu kunomoya wendawo. Lapho umoya wendawo uphuma, ipresha yezinkampani zokugqibela kwe-condenser iphuma kakhulu. Lokhu ipresha encane iyanciphisa umahluko wapresha phakathi kwe-thermostatic expansion valve. Ivalve iyaphambana ukufaka inkampani eyodwa kwi-evaporator coil. Lokhu kubhekisa i-evaporator, kubangela ukuthi ipresha yokuphuma iphuma futhi isuperheat isihamba ku-ma-level amaningi. I-compressor, okuyi-heart yalesistimu, ibhekiswe ukusebenza ngeminyathelo ayayingaqondi. Kungenye, i-lubricating oil engaphakathi kwe-compressor iyagxila futhi iyagxila kakhulu lapho kusukela. I-gas yezinkampani nangokwesibonelo kungafika kwi-sump yewebhile, kuyabambisana ne-oil futhi kuyanciphisa izinkampani zakho zokuhlanya. Lokhu kombini le-ipresha encane yokuphuma, isuperheat esikhulu kakhulu, nokunciphwa kwe-oil kwenza indawo engekhoyo kakhulu kwe-compressor.
Ukuhlanganisa Kwe-Refirigerant Nokuphakanyiswa Kwemithi
Ukuguqula kwe-refrigerant ekhaya lomkhakha kuyisibonelo esikhulu kakhulu sokuthi isistimu sibe nempilo ethile emazulwini amahlanu. Ngeminyaka eyadlula ngokungasebenzi, i-refrigerant vapor endaweni yayo iyaguqula endaweni engezansi kakhulu. Kwi-rooftop unit, indawo engezansi kakhulu ibe yikhaya lomkhakha, okuyizindawo ezihlukene nezulu. Uma i-refrigerant iyagqubha ku-liquid ekhaya lomkhakha, iyahlukanisa ne-lubricating oil. Lokhu kuhlukanisa kunciphisa kakhulu i-viscosity yamaphetha kanye nokuthi ayikwazi ukuvikela i-bearings ne-pistons yomkhakha. Uma umkhakha uqala, ukuphela kwe-pressure kusho kakhulu kusenza i-refrigerant liquid ikhale kakhulu, kususa amaphetha kusuka kwezinto zokusebenza. Lokhu uhlobo lwezindlela, olubizwa ngokuthi liquid slugging, kungasiza ukuthi umkhakha ubhekwe kakhulu ngemizuzu eminingi. Uma akukho crankcase heater okuyikwenza amaphetha abe nemithi kanye nokuvikela ukuguqula kwe-refrigerant, umkhakha wendawo engezansi kuyasebenza kakhulu.
Ukuhlukumezwa Kwesikhombisa Sokuphakama Kwe-Evaporator Coil
Nakuba umshakeli uphumelela kwekholi yokuvula, isikhombisa sokuphakama se-evaporator sibonisa isibindi esinesibindi sokufa. Ngenxa yokuphezulu kwesilinganiso sesandla, ubukhulu bekuphakama kwesikhombisa sokuphakama kwe-rooftop kushushiswa ngokukhulu. Isilinganiso sesandla sesikhombisa sokuphakama singaphansi kwe-freezing ngokushushiswa. Ngenxa yokuphuma kwesandla esinemithi emhlophe kusendla, imithi yasandla iyadlula ngaphezulu kwalokho isikhombisa sokuphakama esikhulu, ibuyela kubona kwe-freezing ngokushushiswa. Isilayela sesifrost sibegcina kusendla sesikhombisa sokuphakama. Lokhu silayela siyasebenza njengesikhombisa sokugcina, sikhululeka ukuthi irefrigerant isihlale isihlale kusandla. Ngenxa yokuthi isilayela sibuyela kubona kwe-freezing, sibuyela kubona kwe-airflow kusendla. Lokhu kushushiswa kubukhulu bekuphakama futhi kubuyela kubona kwe-temperature yesikhombisa sokuphakama. Ukudlula kwe-ice kungabangela ukuthi irefrigerant ibuyela kumshakeli ngendlela yomlando, kubuyela kubona kwe-risk yokudlula ngendlela yomlando.
Ukuthi I-Control Systems Ziyakwenzani Ngokungafanele Ngenxa Yokuphezulu
Izisistimu zokulawula kwe-air conditioner yasekhanda yezindlu ziyaphakanyiswa ngokupheleleyo ngemvula emhlophe. I-low-pressure switch, eyadluliswa ukuvikela i-compressor, inokubhala kabusha ngokungafanele ngokungafanele kwe-suction pressure. I-thermostat inokubhala i-compressor ngokungafanele, njengoba isensor inokubhala izindlela zokuthi ubunzima bungakhona. Lezi zisistimu zokulawula zinokwenza ukuthi izinkinga zezinhlobo zizide kakhulu kwezinkambo. I-compressor inqubekwa ukubhala kabusha, okungavumelela ukuthi ifike ekusenzeni ubunzima obuhle. Lokhu kubhala kabusha kuyabeka umthelela omkhulu kwezinkambo zokugcina nokuthi i-motor windings ziyaphakanyiswa.
Amasolving wokufunda ukusebenza kwezinsuku zemvula emhlophe
Ukuxhumana nalesi zinkinga, abahleli bavusele izikithi zesikhathi esihlukile sokunene esizimele ukusebenza kwe-AC yasezulu ngokuphelele emakhaya okungafanele. Isiqondisi esisodwa kulezi zikithi ngu-crankcase heater. Lezi ziqondisi zezilimi ziyagxilwa ngaphakathi kwesump yomkhisho wokubeka isibonelo futhi ziyabuza umthwalo wokufaka isibonelo ngokuphakeme kusukela ukuthi isibonelo sibekele kumkhisho. Kuyinika ukuthi lapho umkhisho uqala ukusebenza, isibonelo siyisibonelo esihle futhi sisine umthwalo wokufaka isibonelo okuphelele. Isiqondisi esinye esisodwa ngu-suction accumulator. Leli qondiso lisakelwe kumgqa wokubuka phakathi kwe-evaporator ne-mkhisho. Lisakelwe ukuthi libekele isibonelo esingasemva kwe-evaporator, ukuzimela ukuthi isibonelo sifike kumkhisho. Izivinini zokubeka isibonelo esizimele ziyisici esisodwa. Lezi zivinini zisebenzisa izisensor ukuthi zibone ukuthi isibonelo sibekile kwe-evaporator coil. Kanti kubeka isibonelo kuphela lapho kudingeka, okuyenza ukuthi kubhekwe amandla futhi kunciphiseka ukuthi kubhekwe isibonelo esikhulu kusisitemu.
Ukukhetha I-Isiphequlishi Esifanele Kulelimo
Lapho uvakashela i-air conditioner yasezulu yomkhosi kulelimo elibomvu, kubalulekile ukuthi uqiniseke ukuthi leqembu liyanele ngamathuba okwesikhathi esincane. Ukuvakashela kufanele kuchazwe ngokucacile ukuthi kunele i-crankcase heater, i-suction accumulator, nokuthi kunele isistemi sokuhlanza isithunzi sokuzihlanza ngokuzimela. Kulelimo elibomvu kakhulu, kudingeka ukuthi kunele i-low-ambient kit yonke. Le kit ichaza ukuthi kunele ukuthi kubhekwe isithunzi, amafani we-condenser angabonakala ngokuguqula ispeed, nokuthi kunele isistemi sokubuyisa i-hot-gas. Lezizindikimana ziyasebenza ngokuhlanganisa ukuthi kubhekwe isithunzi sokurefrijiya ngokuphelele futhi ukuthi akusisilwe isithunzi sokugcina. Ngokukhetha iqembu eliqondile kulelimo, umphathi wemithombo unakha ukuthi isistemi yokuchitha iyasebenza ngokuphelele ngezinsuku zomhla.
Ubukhulu Bekuphatha Kwemithombo
Ukuphelele kwezinkinga zokusebenza kwe-air conditioner yasezulwini ngaphandle kwezindawo ezingaphansi kwezintemperatura kuyisisekelo esikhulu kubukhulu bekuphatha nokwenza. Ukuphelele kwezinkampani zokuphatha, ubukhulu bekuphatha kwesikrangi kanye nokuphelele kwezinkampani zokuphatha zokuthinta zonke ziyakusinda ukusebenza kwezindawo eziningi. Abahleli abayiqinisekisa ukuthi bafuna ukuthola izindlela zokuphatha ezithembekile, njengoko kufundwa ku-ISO 9001, bakhupha izinkampani zabo zokuphatha kwezindawo ezingaphansi kwezintemperatura ngokuphambuka kwezindawo zokuphatha phambi kokuthi zihlale kwezindawo zokuphatha. Kusukela ekutheni umphathi wezindawo ayizindlela zokuphatha zokuthi amasipho akhona ngokuphambuka kwezindawo zokuphatha ngokuphambuka kwezindawo zokuphatha, ukuthi uyilungele ukuthi uqinisekise ukuthi isistimu iyakwenzeka ngokuphambuka kwezindawo zokuphatha.
