Otu esi echekwa condensers Microchannel na Chillers maka ndụ ogologo ọrụ
Microchannel condensers (ihe bụ isi akụrụngwa nke chillers) nwere ihe aluminom alloy core nwere oghere-tube flat brazed, microscale flow channels (0.1–2 mm), na nnukwu- njupụta louvered/ corrugated ntù. Ndozi nke ọma dị oke mkpa maka ichekwa iguzosi ike n'ezi ihe nhazi ha, nrụpụta ọkụ na-ebufe, na iguzogide corrosion{5}} ihe ndị bụ isi maka ịgbatị ndụ ọrụ nke ndị na-agbanwe okpomọkụ microchannel (MCHEs). N'okpuru ebe a bụ ntuziaka nlekọta zuru oke na-ekpuchi omume dị mkpa yana MCHE{7}}kpọmkwem nkọwa:
1. Nhicha mgbe niile: gbochie mmebi mbufe ọkụ
Ngwu microchannel na ọwa mmiri na-asọpụta na-adịkarị mfe imechi site na uzuzu, unyi, ma ọ bụ ihe refrjiraeto mmanụ, nke na-ebelata ebe ikuku na-ebufe ọkụ dị irè ma na-abawanye ọdịda nrụgide.
Nchacha elu elu:Jiri obere {{0}nrụgide ( Ihe na-erughị ma ọ bụ hà nhata 300 psi) ikuku mpịakọta ma ọ bụ brọsh dị nro{2}} iji wepụ irighiri ihe ndị na-adịghị na ntù a kpara akpa. Maka nkwụnye ego isi ike (dịka ọmụmaatụ, mmanụ, ọnụ ọgụgụ), tinye ndị na-ehicha pH na-anọpụ iche (zere ihe ngwọta acidic/alkaline na-emebi microchannel aluminom) wee kpochaa ya na mmiri deionized. Ghichaa elu azụ nke ọma ka ọ ghara igbochi iru mmiri{7} na-ebute corrosion.Rịba ama: Zenarị elu -ụgbọelu mmiri nrụgide{1}} ha nwere ike na-ehulata ma ọ bụ mebie ntù microchannel ndị siri ike, na-akpaghasị ikuku ikuku na mgbanwe okpomọkụ.
Ọwa Ọwa Na-eru n'ime ime: Kwa afọ na-eji ihe nhicha sistemu refrigerant dakọtara (dịka ọmụmaatụ, polyol ester -ndị na-ehicha ihe maka sistemu R134a/R410A) iji wepụ sludge mmanụ ma ọ bụ oxide. Jikwaa ọ̀tụ̀tụ̀ mmiri na-asọpụta (ihe na-erughị ma ọ bụ hà nhata 10 l/min) iji gbochie mbelata nrụgide gabigara ókè nke nwere ike imebi obere ọkpọkọ- nwere mgbidi.
2. Nchekwa corrosion: Nchekwa Aluminom Alloy Core
Aluminom, ihe bụ isi nke cores MCHE, na-enwe ike ịmịnye corrosion (site na mmiri mmiri, nnu{0}}ikuku juru, ma ọ bụ mmetọ acid). Nchekwa ngwa ngwa dị mkpa:
Nlekọta mkpuchi: Nyochaa mkpuchi mgbochi mpụta - corrosion (dịka ọmụmaatụ, resin phenolic, epoxy, ma ọ bụ mkpuchi fluoropolymer) kwa nkeji. Metụ ebe ndị gbajiri agbaji ma ọ bụ kpụchaa nwere mkpuchi dị elu dakọtara{4}}okpomọkụ{5} ( ọkpụrụkpụ ihe nkiri kpọrọ nkụ: 20–50 μm) iji mechie elu aluminom ekpughere. Maka chillers n'akụkụ oke osimiri, tinye akwa mkpuchi mgbochi nnu- kwa afọ.
Njikwa mmiri mmiri: Gbaa n'aka na akpọchighi ite mmiri condensate nke chiller iji gbochie mmiri kwụ ọtọ ka ọ na-adaba na isi microchannel. Wụnye ihe mgbapụta n'ime ụlọ akụrụngwa ma ọ bụrụ na iru mmiri karịrị 60%- mmiri dị elu na-eme ka corrosion galvanic dị n'etiti ntù aluminum na ahịrị refrigerant ọla kọpa.
Ihe mgbochi corrosion: Tinye ihe mgbochi corrosion dakọtara na loop mmiri chiller (maka mmiri{0}}condensers microchannel jụrụ oyi) iji gbochie nguzobe oke na oxidation metal. Họrọ ihe mgbochi ndị na-adịghị - na-egbu egbu na aluminom (dịka ọmụmaatụ, silicate{5}) inhibitors) iji zere imebi mgbidi microchannel.
3. Nchọpụta nkwụsị: Chekwaa Vacuum{1}}Njikọ gbawara agbawa
Igwe condensers Microchannel na-adabere na oghere-ọhụụ gbawara agbawa n'etiti ọkpọkọ dị larịị na nkụnye eji isi mee - ntapu ebe a na-ebute mfu refrigerant, mbelata arụmọrụ, yana mmebi isi.
Nlele mkpofu Helium oge niile:Na-eme nnwale leak helium (uche: Ihe na-erughị ma ọ bụ haha na 1×10⁻⁹ Pa·m³/s) ọkara - kwa afọ na njikọ refrigerant niile yana oghere{3}} nkwonkwo brazed. Maka nnukwu chillers, jiri ihe nchọta helium nwere ike iji nyochaa nkụnye eji isi mee microchannel wee lekwasị anya na mpaghara ndị nwere ike inwe nrụgide okpomọkụ (dịka ọmụmaatụ, nso inlets/outlets refrigerant).
Nnwale ire nke nrụgide: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 na-egosi ntapu nke chọrọ nrụzi ozugbo (dịka ọmụmaatụ, re{3}}ịkụnye obere nkwonkwo ma ọ bụ dochie tubes dị larịị mebiri emebi).
4. Nleba anya n'ọrụ: Zenarị oke ibu na nrụgide okpomọkụ
Arụ ọrụ na-ezighi ezi (dịka ọmụmaatụ, okpomoku na-ekpo ọkụ nke ukwuu, mgbanwe ọnụego na-asọpụta) na-ebute nrụgide okpomọkụ na akụkụ microchannel, na-eduga n'ike ọgwụgwụ nkwonkwo ma ọ bụ ọkpọkọ tube.
Nlebanya ihe nrụnye igodo:Na-aga n'ihu soro:
Okpomọkụ na-ekpo ọkụ: Debe ya ka ọ na-erughị ma ọ bụ ha nhata na ogo 55 (maka sistemu R134a) iji zere ikpo oke ikuku aluminom -oke okpomọkụ na-ebelata agụụ{3}}brazed bonds.
Mbelata nrụgide: Monitor the refrigerant side pressure drop across the microchannel core; a sudden increase (>20% nke ntọala) na-egosi mmechi ọwa mmiri.
Ọnụego mgbaba: Na-edobe ọnụego refrigerant/ikuku kwụsiri ike (zenarị mwepu mberede) iji gbochie slugging mmiri, nke nwere ike imetụta ma mebie oghere microchannel.
Zenapụnụ-Mbanye mmiri nke okirikiri: Mgbe emechiri chiller (dịka ọmụmaatụ, maka mmezi), debe sekit refrigerant n'okpuru ezigbo nrụgide (Karịrị ma ọ bụ nhata 0.1 MPa) na nitrogen kpọrọ nkụ iji gbochie mmiri mmiri ịbanye microchannels{3} mmiri na-eji mmanụ refrigerant emeghachi omume ka ọ bụrụ acid na-emebi emebi.
5. Omume Nlekọta Kwesịrị Ekwesị: Gbochie Mechanical Mmebi
Ihe owuwu microchannel (tube dị larịị, ntù ndị siri ike) adịghị enwe mmetụta maka nrụpụta ọrụ-iji nlezianya ejizi dị mkpa:
Mgbasa/Mgbakọ echekwara: Mgbe ị na-abanye na condenser, jiri ngwaọrụ ebuli elu kwesịrị ekwesị (dịka ọmụmaatụ, clamps padded) iji zere ịgbado ọkpọkọ dị larịị ma ọ bụ gwepịa nku microchannel. Edokwala ihe ndị dị arọ na isi MCHE, n'ihi na nke a nwere ike imebi ọwa mmiri na-asọ asọ.
Nyocha nkwonkwo: Kwa nkeji, lelee iguzosi ike n'ezi ihe nke brackets na-arị elu na ihe mgbochi ịma jijiji{0}} na-eme ka isi microchannel maa jijiji, na-eduga na ike ọgwụgwụ na nkwonkwo brazed ka oge na-aga. Jisie ike na nkọwa torque nke onye nrụpụta (na-abụkarị 8-12 N·m maka brackets aluminum).
Ọrụ ọkachamara: Maka nnukwu nrụzi (dịka ọmụmaatụ, dochie tubes flat mebiri emebi, re{2}}brazing nkụnye eji isi mee), jiri ndị ọkachamara zụrụ azụ na mmezi MCHE. Ịme brazing na-ezighi ezi nwere ike igbochi microchannel ma ọ bụ mepụta nkwonkwo adịghị ike, na-ebelata ndụ ọrụ condenser.
Site n'ilekwasị anya na nhicha mgbe niile, nchedo corrosion, nchọpụta ntanye, nleba anya arụ ọrụ, na iji nlezianya mee ihe, ị nwere ike ịgbatị ndụ ọrụ microchannel condensers na chillers - na-adịkarị site na afọ 8-10 ruo afọ 12-15. Omume ndị a abụghị naanị na-echekwa ihe MCHE dị oke egwu (aluminum core, vacuum- nkwonkwo brazed, microscale flow channel) kamakwa na-ejigide arụmọrụ mbufe okpomọkụ kacha mma, na-ebelata ogologo oge- ụgwọ ọrụ chiller.
Ihe nchịkọta dị ọkụ: micro-ọwa chiller condenser coil, China micro{1}}channel chiller condenser coil emepụta, ndị na-ebubata, ụlọ ọrụ mmepụta ihe.
