Maitiro Ekuona Kana Condenser Kana Evaporator Yakakuvadzwa?

 

 

Condensers uye evaporators ndiwo akakosha ekutsinhana kwekushisa kwemafiriji masisitimu, uye chimiro chavo chekushanda chinokanganisa kunyatsoita kwefiriji uye kugadzikana kwehurongwa. Kuona kana dzakuvadzwa kunoda kusanganisa ongororo yekuona, yekutarisa paramende, kuongororwa kwekuita, uye nzira dzekubatsira dzekuyedza. Heano maitiro akasarudzika ekutonga:

1. Kuongorora Kwekuona

1.1 Condenser Visual Inspechiito

 

Kukuvadzwa mumuviri: Tarisa kana condenser's copper/stainless simbi machubhu akabhenda, akaremara, kana kutyoka. Kumhepo-yakatonhodzwa macondenser, mahombe-akaputsika kana kutyoka zvimbi zvinoderedza kuyerera kwemhepo uye kudzikisira zvakanyanya kupisa. Nezvemvura-yakatonhodzwa macondenser, ongorora goko kana pakatsemuka kana kubvinza; mavara emvura, ngura, kana mavara emafuta emufiriji anoratidza mukana mukuru wekudonha.

Fouling accumulation: Hupfu, oiri, kana sikero yakakora (mumvura-yakatonhodzwa mayunitsi) panzvimbo yecondenser inoita sekudzivirira, zvichiita kuti kupisa kusina kunaka. Mumamiriro ezvinhu akajairika, nzvimbo yacho inofanira kuva yakachena; kusvibisa pamusoro pe0.5mm gobvu (kunyangwe pasina kukuvara) kunogona kukonzeresa kukanganisa kushanda-kusiyanisa pakati pe "fouling blockage" ne "本体 kukuvara".

Corrosion: Munzvimbo dziri pedyo negungwa kana kuti dzine mwando wepamusoro, mapaipi econdenser anogona kuita ngura. Madhuri epombi akatetepa kana gomba/perforation zvinokonzeresa kudonha kwefiriji, zvichiita kukuvara kwakanyanya.

1.2 Evaporator Visual Inspection

 

Abnormal frosting/icing: Yakajairika evaporator inofanirwa kuve neuniform yakaonda chando. Mazaya echando emunharaunda kana chando chisina kuenzana (semuenzaniso, chando chakanyanya painopinza, pasina chando chinobuda) chinogona kuratidza kuvharika kwepombi, firiji isina kukwana, kana kuvuza kwemukati. Kusavapo kwechando zvachose kunoda kutariswa kuti hakuna kubuda kana kutsemuka kwepombi.

Leak traces: Oiri mamaki pane evaporator pamusoro (firiji inosanganiswa nemafuta efiriji uye inobuda nayo), kunyanya pamajoini epombi uye welds, zviratidzo zvekudonha. Pazvakavakwa-mumaevaporator, tarisa kana insulation iri kunyorova; mold kana sepeji yemvura mukudzivirira inogona kuperekedza evaporator perforation.

Kukuvadzwa mumuviri: Mapombi evaporator akatetepa{{0}mabono, akatsemuka kubva pakubatwa, kana kutyoka machubhu ekuchinja kupisa anobvisa zvachose huwandu hwekuchinjana kupisa.

2. Operational Parameter Monitoring

2.1 Tembiricha Parameter Kuenzanisa

 

Condenser: Panguva yekushanda kwemazuva ese, mupimo wemhepo-musiyano wekubuda kwetembiricha yemhepo-macondenser akatonhodzwa i8–12 degrees, uye inopinza mvura-musiyano wekubuda kwemvura-macondenser akatonhodzwa i4-6 degrees. Musiyano mudiki wetembiricha (<5℃) may indicate insufficient heat exchange area (e.g., damaged fins), refrigerant leakage, or fan/pump failure. An excessively large temperature difference with high-pressure alarms may signal condenser blockage or internal pipe damage causing abnormal heat exchange efficiency.

Evaporator: Musiyano-mukubuda tembiricha yemasisitimu ekufefetera mhepo unofanira kuva 10–15 degrees. Musiyano mudiki unogona kuratidza kusvibiswa kwe evaporator, kudonha kwemukati, kana kusakwana kuyerera kwefiriji. Tembiricha yakaderera zvisingaite (<0℃) with persistent icing may stem from pipe blockage or sensor faults, which can cause evaporator freezing and cracking over time.

2.2 Kudzvanya Parameter Kuona

 

Shandisa gauge yepressure kuyera system yakakwirira uye yakaderera pressure: PaR22 refrigerant, yakajairika high pressure (condenser side) i1.4–1.8MPa, uye yakajairika low pressure (evaporator side) i0.4–0.6MPa.

Kudzikira kwepamusoro uye kuderera kwakanyanya: Mukana mukuru wekudonha kwemukati (refrigerant cross-kuyerera) mucondenser kana evaporator.

Yakakwira yakakwira uye yakaderera kudzvanywa: Inogona kuratidza kuvharika kwecondenser kana evaporator pombi kukuvara kunokanganisa kutenderera kwefiriji.

Yakaderera yakakwirira uye yakaderera kudzvinyirira: Tarisa kune refrigerant leakage (evaporator/condenser perforation).

3. Performance Evaluation

3.1 Yakaderedzwa Kutonhora / Kupisa Kugona

 

Kana tembiricha yemukati / yekuchengetedza ikatadza kusvika kune yakatarwa kukosha (mushure mekutonga kunze compressor kana throttling component kukanganisa), funga evaporator kana condenser kukanganisa: Evaporator kukuvara kunoderedza kupisa kupisa; kukuvadzwa kwecondenser kunokonzeresa kunyungudika kwekupisa, zvichiita kuti{{0}dzivirirwe zvakanyanya uye kukanganisa firiji.Muenzaniso: Air conditioner evaporator leak inotungamira kune yakakwira indoor unit outlet tembiricha yemhepo, ine condenser yekunze ichimhanya asi isina kutonhora. Kukuvadzwa kwakanyanya kwe condenser fin kunokonzeresa tembiricha yakakwira zvakanyanya-paipi yepressure (kunyangwe iine fan yakajairika kunze) uye kazhinji kudzimwa kwesystem.

3.2 Ruzha rusina kujairika uye kudedera

 

Metallic friction kubva kune condenser fan inogona kuratidza yakaremara zvimbi zvichikwesha fan blades kanamapombi econdenser akasununguka achibonderananegoko.

Inzwi rekuti "hissing" rinobva pamupombi rinogona kuratidza kukuvadzwa kwepombi yemukati (kudonha kwefiriji) kana kutsemuka kwepombi panguva yekunyunguduka mushure meicing.Kuzunguzika kwenguva refu-kunowedzera kutsemuka kweweld, kuwedzera kukuvadzwa.

4. Nzira dzekubatsira dzekuedza

4.1 Mhepo Kusimba Muedzo

 

Zadza sisitimu nenitrogen (1.8-2.0MPa) uye bata kudzvanywa kwemaawa makumi maviri nemana: Kudonha kwekumanikidza kunodarika 0.05MPa kunoratidza kuvuza. Tsvaga panobuda mvura nekuisa mvura ine sipo kune evaporator/condenser pombi majoini nemawelds (tarisa mabubbles). Normal pressure kubata asi abnormal operational pressure inogona kuratidza yakavanzika yemukati kukuvara kwepombi.

4.2 Infrared Imaging Detection

 

Skena evaporator/condenser pamusoro ne infrared thermal imager: Zvakajairwa zvinopisa kupisa zvine kugovera tembiricha yakafanana. Nzvimbo dzepanzvimbo yepamusoro/yakaderera tembiricha dzinoratidza kuvharika kwepombi, kuvuza, kana kusatsinhana kwekushisa, zvichigonesa kukuvara chaiko.

4.3 Oiri Sample Analysis

 

Bvisa oiri yemufiriji kubva mugadziriro: Metal debris (kubva kuevaporator/condenser pipe wear) kana kunyorova kwakanyanyisa (kubva pakukuvadzwa kwepombi nekupinda kwemvura) muoiri inoratidza kukuvara kwemuchina-kuparadzana uye kuongorora.

Summary

 

Kuona kukuvara kwecondenser/evaporator kunoda mana-dimensional maitiro: "visual inspection - parameters - performance - test". Rongedza macheki ekuona kuti ubvise zvikanganiso zvepasi, wobva washandisa zviridzwa kuona parameter abnormalities, uye pakupedzisira simbisa kukuvara kwerudzi zvichienderana nekuita kwekushanda. Mukugadzirisa kwemazuva ese, gara uchichenesa nzvimbo dzekuchinjana kupisa uye tarisa ma paramita ekushanda kuti uone kukuvadzwa kwakavanzika nekukurumidza uye kudzivirira kukanganisa kukwira.
