Nzira yekusarudza yakakodzera air duct hita?

Nekuti iyo air duct hita inonyanya kushandiswa muindasitiri. Zvinoenderana nezvinodiwa tembiricha, vhoriyamu yemhepo zvinodiwa, saizi, zvinhu uye zvichingodaro, sarudzo yekupedzisira ichave yakasiyana, uye mutengo uchavewo wakasiyana. Kazhinji, kusarudzwa kunogona kuitwa maererano nemapoinzi maviri anotevera:

1. Wattage:

Kusarudzwa kwakarurama kwemvura kunogona kusangana nesimba rinodiwa nekupisa svikiro, chengetedza kuti heater inogona kusvika kune inodiwa temperaturw kana ichishanda. Zvadaro, tiye anotevera zvinhu zvitatu zvinofanirwa kutariswa pakusarudza kwekuverenga kwemvura:

(1) Pisa tembiricha yekudziya kubva kune yekutanga tembiricha kuisa tembiricha mukati menguva yakatarwa;

(2) pasi pemamiriro ekushanda, simba rinofanira kukwana kuchengetedza tembiricha yepakati;

(3) Panofanira kunge paine imwe nzvimbo yakachengeteka, kazhinji inofanirwa kunge iri 120%.

Zviripachena, iyo yakakura wattage inosarudzwa kubva (1) uye (2), uyezve, iyo yakasarudzwa wattage inowedzerwa neyakachengetedzeka margin.

2. Kukosha kwekugadzira kwekumhanya kwemhepo:

Kuyerwa kwemhepo yekumanikidza, kumhanya kwemhepo uye vhoriyamu yemhepo inogona kuitwa nepitot chubhu, U-mhando manometer, tilting micro-manometer, inopisa bhora anemometer uye zvimwe zviridzwa. Pitot chubhu uye U-mhando manometer inogona kuyedza iyo yakazara kudzvanywa, kusimba kwesimba uye static kudzvanywa mumhepo duct hita, uye mamiriro ekushanda einofuridza uye kuramba kweiyo ventilation system inogona kuzivikanwa nekuyerwa kwese kumanikidzwa. Huwandu hwemhepo hunogona kushandurwa kubva kune yakayerwa dynamic pressure. Tinogona zvakare kuyera kumhanya kwemhepo neinopisa bhora anemometer, tobva tawana huwandu hwemhepo hunoenderana nekumhanya kwemhepo.

1. Batanidza fan uye pombi yemhepo;

2. Shandisa tepi yesimbi kuyera ukuru hwemhepo duct;

3. maererano nehupamhi kana rectangular duct size, sarudza nzvimbo yekuyera nzvimbo;

4. Vhura gomba rakatenderera (φ12mm) pamhepo duct panzvimbo yekuedza;

5. Maka nzvimbo yekuyera mapoinzi papitot chubhu kana inopisa bhora anemometer;

6. Batanidza picot tube uye U-type manometer ne latex tube;

7. Pitot chubhu kana bhora rinopisa anemometer rinoiswa vertically mumhepo duct pagomba rekuyeresa, kuitira kuti ive nechokwadi chekuti nzvimbo yekuyeresa ndiyo yakarurama, uye teerera kune kutungamirirwa kwepitot tube probe;

8. Verenga kumanikidzwa kwese, simba rekuita uye static pressure mu duct zvakananga paU-shaped manometer, uye uverenge mhepo inomhanya mubhoti zvakananga pane inopisa bhora anemometer.
