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.
1. Kana iyo unit isiri kushanda munguva yechando, mvura yose iri muhurongwa inofanira kusunungurwa kudzivirira coil crack.
2. Pamamiriro ezvinhu ekukurumidzira akadai sekudzima kwemagetsi kana kugadzirisa magetsi, damper yemhepo inofanira kuvharwa pakarepo kuti ione kuti hapana kunze kwemhepo inopinda muhurongwa.Fluid haisi kudhonzwa kuburikidza necoil uye tembiricha inodonha mukati meAHU inogona kukonzera kuumbwa kweaizi.Tembiricha iri mukati meAHU inofanira kuramba iri pamusoro pe5 ℃.
3. 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.
4. Kutadza kudzora hurongwa hwekugadzira.Mamwe masisitimu ekudzora anongogadzirisa kuvhurika kwevharuvhu yemvura kwete kumhanya kwe fan kunoenderana nemukati tembiricha controller.Kushaikwa kwekudzora feni kunokonzeresa kutenderera kwemvura isina simba uye huwandu hwemhepo, zvichikonzera mvura yakaoma mucoil.(Iyo yakajairwa kumhanya kwemvura mucoil inofanirwa kudzorwa pa 0.6 ~ 1.6m/s)
Kutenderera kwecoil uko kudzvanywa kunovaka, uye nzvimbo isina kusimba mudunhu iroro.Kuongorora kwakanyanya kwakaratidza kuti kukundikana 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 ice iyi inogona chete kubata iyi yakawedzera kudzvanywa kutozosvikira yasvika painogumira iyo inokonzera kupisa exchanger kukuvara uye kunotevera kutadza.
Kana iwe uine chero mibvunzo ine chekuita nemhepo inobata unit kuchengetedzwa kwechando, bata Airwoods nhasi!Isu tiri kutungamira mupi wepasi rose wezvigadzirwa zveHVAC zvitsva uye kuvaka mhinduro yemhando yemhepo kumisika yekutengeserana neyemaindasitiri.Kuzvipira kwedu kupa vatengi vedu zvigadzirwa zvemhando yepamusoro uye masevhisi pamutengo unokwanisika uye kugadzira nharaunda yekugara iri nani.
