WINTER MAINTENANCE GUIDE YEHOLTOP AIR HANDLING UNIT COIL

Mvura yakashandiswa kutonhodza uye kupisa mweya mufinned-tube heat exchange coils kubvira pakatanga kudziyisa uye air conditioning. Kutonhora kwemvura uye kukuvara kwecoil kwave kwakatenderedza kwehurefu hwakafanana hwenguva. Iro idambudziko rakarongeka iro nguva zhinji rinodzivirika. Muchinyorwa chino, isu takanyora mashoma matipi anokubatsira iwe kudzivirira yakaomeswa crack coil munguva yechando.

Kana iyo unit isiri kushanda munguva yechando, mvura yese iri muhurongwa inofanira kuburitswa kudzivirira kutsemuka kwecoil.

Pamamiriro ezvinhu ekukurumidzira akadai sekudzima kwemagetsi kana kugadzirisa magetsi, damper yemhepo inofanirwa kuvharwa nekukasira kuti ive nechokwadi chekuti hapana mweya wekunze unopinda muhurongwa. Fluid haisi kudhonzwa kuburikidza necoil uye tembiricha inodonha mukati meAHU inogona kukonzera kuumbwa kweaizi. Tembiricha iri mukati meAHU inofanira kuramba iri pamusoro pe5 ℃.

Kuchenesa Coil uye sefa yemvura nguva dzose. Zvinhu zvakanamira mupombi zvichikonzera kusafamba zvakanaka kwemvura. Liquid trap mucoil chubhu zvichikonzera kukuvara kwecoil kana mamiriro echando aripo.

Kutadza kutonga system dhizaini. Mamwe masisitimu ekudzora anongogadzirisa kuvhurika kwevharuvhu yemvura kwete kumhanya kwefani zvichibva pane yemukati tembiricha controller. Kushaikwa kwekutonga kwe fan kunokonzeresa kutenderera kwemvura kusina simba uye kukwirira kwemhepo, zvichikonzera mvura yakaoma mucoil. (Iyo yakajairwa kumhanya kwemvura mucoil inofanirwa kudzorwa pa 0.6 ~ 1.6m/s)

AHU coil maintenance

Kutenderera kwecoil uko kudzvanywa kunovaka, uye nzvimbo isina kusimba mudunhu iroro. Kuongorora kwakadzama kwakaratidza kuti kutadza kuchaonekwa senzvimbo yakavharwa mumusoro wechubhu kana bend yakawedzera. Muzviitiko zvakawanda, ndiyo nzvimbo inoputika.

Ndokumbira utarise pazasi kuti uwane kuverengera kwekumanikidza nekuda kwecoil yakaomeswa nechando.

P=ε×E Kg/cm2

ε = Kuwedzera Kuwedzera (Chimiro: 1 atmospheric pressure, 0 ℃, volume ye1 kg mvura)

ε = 1÷0.9167=1.0909 (9% Volume kuwedzera)

E = modulus ye elasticity mukushushikana (Ice = 2800 Kg/cm2)

P=ε×E=(1.0909-1)×2800=254.5 Kg/cm2

Kudzvinyirirwa kwakashata ndicho chikonzero chekukuvara kwechando kune coil. Kukuvadzwa kwecoil nekuda kwemutsetse wemvura kutonhora kunoenderana nekudzvinyirira kwakanyanya kunogadzirwa panguva yekuumbwa kweaizi. Nzvimbo ine aizi iyi inogona chete kubata iyi yakawedzera kudzvanywa kusvika yasvika painogumira iyo inokonzera kupisa exchanger kukuvadzwa uye kunotevera kutadza. 

Kana iwe uine chero mibvunzo ine chekuita nemhepo inobata unit kuchengetedzwa kwechando, taura nesu!
