Ungayikhetha kanjani i-heater yomoya elungile?

Ngoba i-air duct heater isetshenziswa ikakhulukazi embonini. Ngokwezidingo zokushisa, izidingo zevolumu yomoya, usayizi, impahla nokunye, ukukhethwa kokugcina kuzohluka, futhi intengo nayo izohluka. Ngokuvamile, ukukhetha kungenziwa ngokuya ngamaphuzu amabili alandelayo:

1. Watage:

Ukukhetha okulungile kwe-wattage kungahlangabezana namandla adingekayo ngokushisa okuphakathi, qiniseka ukuthi i-heater ingafinyelela endaweni edingekayo yokushisa lapho isebenza. Ngemuva kwalokho, tUlandela izici ezintathu kufanele kubhekwe ekukhetheni kwesibalo sakwaWatge:

(1) Fudumeza okuphakathi nendawo kusuka ekushiseni kokuqala ukusetha izinga lokushisa esikhathini esibekiwe;

(2) Ngaphansi kwezimo zokusebenza, amandla kufanele anele ukulondoloza izinga lokushisa eliphakathi;

(3) Kufanele kube ne-margin ethile ephephile, imvamisa kufanele ibe ngu-120%.

Ngokusobala, ikheji elikhudlwana likhethiwe kusuka (1) no (2), bese kuthi-ke, i-wattage ekhethiwe iphindaphindwe yi-margin ephephile.

2. Inani lokuklama leIjubane lomoya:

Ukulinganisa kwengcindezi yomoya, ijubane lomoya kanye nevolumu yomoya kungenziwa nge-pitot tube, uhlobo lwe-manometer, ukuthambisa i-micro-manometer, i-anemometer eshisayo, i-anemometer eshisayo ne-anemometer nezinye izinsimbi. I-Pitot Tube ne-U-Type Manometer ingavivinya ingcindezi ephelele, ingcindezi enamandla kanye nengcindezi ye-static ku-heater ye-air duct heater, kanye nesimo sokusebenza kwesistimu yokungena komoya ongaziwa ngokucindezela okulinganiselwe okulinganiselwe. IVolumu Yomoya ingaguqulwa kusuka ekucindezelweni okunamandla okulinganiswayo. Singakwazi futhi ukukala isivinini somoya nge-anemometer eshisayo ye-anemometer, bese uthola ivolumu yomoya esivinini somoya.

1. Xhuma ipayipi lomlandeli kanye nomoya omncane;

2. Sebenzisa itheyiphu yensimbi ukukala usayizi we-duct yomoya;

3. Ngokuya ngewabuli noma usayizi we-duct exande, nquma indawo yephuzu lokulinganisa;

4. Vula umgodi oyindilinga (φ12mm) ku-duct yomoya endaweni yokuhlola;

5. Maka indawo yamaphoyinti wokulinganisa ku-pitot tube noma ibhola elishisayo anemometer;

6. Xhuma i-picot tube ne-manometer yohlobo lwe-U-Type nge-latex tube;

7

8. Funda ingcindezi ephelele, ingcindezi eshukumisayo kanye nengcindezi ye-tuli ku-duct ngqo kwi-manometer ebekiwe, bese ufunda isivinini somoya ku-duct ngqo ku-anemometer eshisayo.
