Engeri y'okulabirira microchannel condensers mu chillers for extended service life .

Microchannel condensers (ekitundu ekikulu ekya chillers) zirina aluminium alloy core nga erimu vacuum-bulezi flat tubes, microscale flow channels (0.1–2 mm), ne high-density louvered/corrugated fins. Okuddaabiriza okutuufu kikulu nnyo mu kukuuma obulungi bwabyo obw’enzimba, obulungi bw’okutambuza ebbugumu, n’okuziyiza okukulukuta-Ensonga enkulu ez’okugaziya obulamu bw’okuweereza kw’ebintu ebikyusa ebbugumu mu microchannel (MCHEs). Wansi waliwo ekitabo ekikwata ku ndabirira mu bujjuvu ekikwata ku nkola enkulu ne MCHE-Ebigambo ebitongole:

1. Okwoza buli kiseera: okuziyiza okuvunda kw’okutambuza ebbugumu .

Microchannel fins ne flow channels zitera okuzibikira enfuufu, obucaafu, oba ebisigadde mu woyiro ebifuumuula, ebikendeeza ku bunene bw’ebbugumu erikola obulungi ku ngulu n’okwongera okukka kwa puleesa.

Okuyonja ku ngulu ku FIN .: Kozesa wansi-okunyigirizibwa ( okutono oba okwenkana 300 psi) empewo enyigiriziddwa oba bbulawuzi ennyogovu-okuggya ebisasiro ebikalu okuva mu biwaawaatiro bya louvered/corrugated. Ku bitereke ebikaluba (okugeza, amafuta, minzaani), teekako pH ezitaliimu (okwewala asidi/alkaline solutions ezonoona microchannels za aluminiyamu) n’okunaaza n’amazzi agataliimu ayoni. Kaliza bulungi ku ngulu w’ekiwaawaatiro okuziyiza obunnyogovu-okuva ku bunnyogovu obuleetebwa.Ebbaluwa: Weewale ebiwujjo by’amazzi ebya waggulu-ebinyigiriza-biyinza okugoya oba okwonoona ebiwaawaatiro bya microchannel ebigonvu, okutaataaganya empewo okutambula n’okuwanyisiganya ebbugumu.

Okufuuwa omukutu gw’okukulukuta okw’omunda .:Ansubulula amakubo g'okukulukuta kwa microchannel n'ekintu ekikwatagana eky'enkola ya firiigi (okugeza, polyol ester-ebirongoosa ebyesigamiziddwa ku nkola za R134A/R410A) okuggyawo ebisasiro by'amafuta oba oksayidi. Fuga omuwendo gw’amazzi agakulukuta ( less than or equal to 10 l/min) okuziyiza okugwa kwa puleesa okuyitiridde okuyinza okwonoona ebipimo ebigonvu-ebipapajjo ebiteekeddwa mu bbugwe.

2. Okukuuma okukulukuta: Okukuuma Aluminium Alloy Core .

Aluminiyamu, ekintu ekikulu eky’emisingi gya MCHE, kisobola okukwatibwa okukulukuta (okuva mu bunnyogovu, omunnyo-empewo ejjudde, oba obucaafu bwa asidi). Obukuumi obw’okusooka (proactive protection) kyetaagisa nnyo:

Okuddaabiriza Okusiiga Ebizigo .:Weekenneenya anti-ekizigo ekikulukuta (okugeza, ebirungo ebiyitibwa phenolic resin, epoxy, oba fluoropolymer coatings) buli luvannyuma lwa myezi esatu. Touch up chipped or peeled areas with a matching high-ebbugumu -okuziyiza (obuwanvu bwa firimu enkalu: 20–50 μm) okusiba ebitundu bya aluminiyamu ebirabika. Ku chillers mu bitundu by’oku lubalama lw’ennyanja, teekako layer endala eya anti-Salt spray coating buli mwaka.

Okufuga obunnyogovu .:Ekakasa nti ekiyungu kya chiller's condensate drain kizirika okuziyiza amazzi agayimiridde okutonnya ku microchannel core. Teeka ekyuma ekiggya obunnyogovu mu kisenge ky’ebyuma singa obunnyogovu busukka ebitundu 60%-obunnyogovu obw’amaanyi obwanguyira okukulukuta kwa galvanic wakati w’ebiwaawaatiro bya aluminiyamu ne layini ezifuumuula ekikomo.

Ebiziyiza okukulukuta .:Add compatible corrosion inhibitors to the chiller's water loop (olw'amazzi-ebiwujjo bya microchannel ebinyogoze) okuziyiza okutondebwa kwa minzaani n'okuziyiza okw'ekyuma. Londa ebiziyiza ebitali -eby’obutwa ku aluminiyamu (okugeza, silicate-ebiziyiza ebisinziira ku) okwewala okwonoona ebisenge bya microchannel.

3. Okuzuula okukulukuta: Okukuuma vacuum-Ebiyungo ebisibiddwa .

Microchannel condensers zeesigamye ku vacuum-ensengekera ezisibiddwa wakati wa ttanka ezipapajjo n’emitwe-eleeka wano zireeta okufiirwa kwa firiigi, okukendeeza ku bulungibwansi, n’okwonooneka kw’omusingi okuyinza okubaawo.

Okugezesa okukulukuta kwa helium okwa bulijjo .:Okukebera okukulukuta kwa heliyamu (Sensitivity: less than or equal to 1×10⁻⁹ pa·m3/s) semi-Annual ku biyungo byonna ebya firiigi n'obuziba-ebiyungo ebisibiddwa. Ku chillers ennene, kozesa ekintu ekiyitibwa portable helium detector okusika emitwe gya microchannel ne fin-tube interfaces-essira ku bitundu ebitera okubeera n’okunyigirizibwa kw’ebbugumu (okugeza, okumpi ne firiigi eziyingira/ebifulumizibwa).

Okugezesa okuvunda kwa puleesa .:Monthly perform a pressure decay test on the refrigerant circuit: Charge the system with dry nitrogen (pressure: 1.5× the design working pressure, typically 2–3 MPa) and monitor for pressure drops over 24 hours. A drop >0.01 MPa eraga okukulukuta okwetaaga okuddaabirizibwa amangu (okugeza,-okusiba obuyungo obutono oba okukyusa obuyumba obupapajjo obwonooneddwa).

4. Okulondoola emirimu: Weewale okuyitirira n’okunyigirizibwa mu bbugumu .

Okukola obubi (okugeza, ebbugumu erisukkiridde ery’okufuumuuka, okukyukakyuka kw’omuwendo gw’amazzi agakulukuta) kuleeta okunyigirizibwa okw’ebbugumu ku nsengekera za microchannel, ekivaako okukoowa kw’ekiwanga oba okukutuka kwa ttanka.

Okulondoola kwa parameter okukulu .:Okulondoola buli kiseera:

Ebbugumu erifukirira .: Kikuume nga kitono oba nga kyenkana 55℃(ku nkola za R134A) okwewala okubuguma ennyo omusingi gwa aluminiyamu-ebbugumu eringi linafuya vacuum-Brazed bonds.

Okugwa kwa puleesa .: Monitor the refrigerant side pressure drop across the microchannel core; a sudden increase (>20% ku baseline) kiraga okuziba kw’emikutu gy’okukulukuta.

Omuwendo gw’amazzi agakulukuta .: Kuuma emiwendo gya firiigi/empewo egy’enkalakkalira (okwewala okulinnya amangu) okuziyiza okusannyalala kw’amazzi, ekiyinza okukosa n’okwonoona ebiggulo bya microchannel.

Weewale off-Okuyingira obunnyogovu bw'enzitoya .:Ekiyungo bwe kiggalwa (okugeza, okuddaabiriza), kuuma circuit y’ekifuumuula wansi wa puleesa ennungi ( esinga oba eyenkanawa ne 0.1 MPa) ne nayitrojeni omukalu okuziyiza empewo ennyogovu okuyingira mu microchannels-obunnyogovu bukolagana n’amafuta agafuumuula okukola asidi eziwunya.

5. Enkola entuufu ey’okuddaabiriza: Okuziyiza okwonooneka kw’ebyuma .

Ebizimbe bya microchannel (ebisenge ebiwanvu ebiwanvu, ebiwaawaatiro ebigonvu) biri mu bulabe bw’okukosebwa kw’ebyuma-okukwata n’obwegendereza kikulu nnyo:

Safe disassembly/assembly .:Bw’oba ​​oyingira mu kondensa, kozesa ebikozesebwa ebituufu eby’okusitula (okugeza, ebikwaso ebiriko padding) okwewala okufukamira ebipipa ebipapajjo oba ebiwaawaatiro bya microchannel ebimenya. Toteeka bintu bizito ku MCHE core, kubanga kino kiyinza okufuula emikutu gy’okukulukuta egy’omunda.

Okukebera awamu .:Quarterly check the integrity of mounting brackets and vibration dampeners-Loose brackets zireetera microchannel core okukankana, ekivaako okukoowa mu brazed joints okumala ekiseera. Ssiba ebisiba ku torque y’omukozi (mu ngeri entuufu 8–12 n·m ku brackets za aluminiyamu).

Okukola saaviisi mu ngeri ey’ekikugu .:Ku kuddaabiriza okw'amaanyi (okugeza, okukyusa obuyumba obupapajjo obwonooneddwa, RE-emitwe egy'okusiba), bakozesa abakugu abatendekeddwa mu kuddaabiriza MCHE. Okusiba ebikonde ebitali bituufu kuyinza okuziyiza microchannels oba okukola ebiyungo ebinafu, ne kikendeeza ku bulamu bwa kondensa.

Bw’ossa essira ku kuyonja buli kiseera, okukuuma okukulukuta, okuzuula okukulukuta, okulondoola emirimu, n’okukwata obulungi, osobola okugaziya ennyo obulamu bw’okuweereza kwa microchannel condensers mu chillers-mu bujjuvu okuva ku myaka 8–10 okutuuka ku myaka 12–15. Enkola zino tezikoma ku kukuuma bitundu bya MCHE ebikulu (aluminum core, vacuum-ebiyungo ebisibiddwa, emikutu gy’amazzi agakulukuta mu microscale) naye era bikuuma obulungi obulungi okutambuza ebbugumu, okukendeeza ku nsaasaanya y’emirimu ey’ekiseera ekiwanvu-term chiller.
