Kuisa Ducts uye Outlets

Basic Installation Zvinodiwa
1.1 Paunenge uchishandisa flexible ducts ekubatanidza zvitoro, kureba kwavo hakufanirwe kudarika 35cm kuve nechokwadi chekushanda kwakakwana.

1.2 Pamadhakisi emhepo anoshandisa tubing inochinjika, kureba kwepamusoro kunofanirwa kugumira kumamita mashanu. Pamusoro pehurefu uhu, maPVC ducts anokurudzirwa kuti aite zvirinani uye kusimba.

1.3 Mafambisirwo emadhaivhi, madhayamita awo, uye nzvimbo dzekumisikidza dzezvitoro zvinofanirwa kunyatso kuomerera kune zvakatsanangurwa mudhizaini yedhizaini.

1.4 Ita shuwa kuti mativi akachekwa echubhu akatsetseka uye haana mabhura. Kubatana pakati pemapombi uye mafittings kunofanirwa kuve kwakachengeteka riveted kana kunamwa, kusasiya pasina glue rakasara panzvimbo.

1.5 Isai madhaidhi akachinjika nhanho uye yakatwasuka pombi kuti uchengetedze kutendeseka kwechimiro uye mafambiro emhepo. Ita shuwa kuti dhayamita yemukati yetubhing yakachena uye haina marara.

1.6 PVC ducts dzinofanira kutsigirwa uye kusungirirwa uchishandisa mabhuraketi kana hangers. Kana ma clamps akashandiswa, nzvimbo dzadzo dzemukati dzinofanira kunge dzakasimba kumadziro ekunze kwepombi. Makomo uye mabhuraketi anofanirwa kusimbiswa zvakasimba kune ducts, pasina chero zviratidzo zvekusunungura.

1.7 Mapazi e ductwork anofanirwa kugadziriswa panguva dzakasiyana, uye nguva idzi dzinofanira kuenderana neanotevera zviyero kana zvisina kutsanangurwa mudhizaini:

- Kune madhaidhi akachinjika, ane madhayamita kubva pa75mm kusvika 125mm, poindi yekumisikidza inofanira kuiswa yega yega 1.2 metres. Pamadhayamita ari pakati pe160mm ne250mm, gadzirisa 1.6 metres yega yega. Pamadhayamita anopfuura 250mm, gadzirisa 2 metres yega yega. Pamusoro pezvo, ese magumo emagokora, couplings, uye majoini e tee anofanirwa kuve nenzvimbo yekumisikidza mukati me200mm yekubatanidza.

- Kune madhaidhi akatwasuka, ane madhayamita ari pakati pe200mm ne250mm, gadzirisa mamita matatu ega ega. Pamadhayamita anopfuura 250mm, gadzirisa 2 metres yega yega. Zvakafanana nema ducts akatwasuka, ese magumo ekubatanidza anoda kugadzirisa mapoinzi mukati me200mm.

Flexible metallic or non-metallic ducts haafanire kudarika 5 metres pakureba uye anofanirwa kunge asina mabhendi akapinza kana kudonha.
1.8 Mushure mekuisa madhaivhi kuburikidza nemadziro kana pasi, nyatsovhara uye gadzirisa chero maburi kudzivirira kubuda kwemhepo uye kuve nechokwadi chekuvimbika kwechimiro.

Nekutevedzera aya akadzama ekuisa nhungamiro, unogona kuve nechokwadi chekushanda kwakaringana uye hupenyu hurefu hwakopekugara patsva air ventilation system,kusanganisiramudzimba kupisa kupora kufefetedza(DHRV) uye yakazaraimba kupisa kupora ventilation system(WHRVS), ichikupa mweya wakachena, unoshanda, uye unodzorwa tembiricha mumba mako.
