Chifukwa chotenthetsera mpweya chimagwiritsidwa ntchito makamaka m'makampani. Malingana ndi zofunikira za kutentha, zofunikira za mpweya, kukula, zinthu ndi zina zotero, kusankha komaliza kudzakhala kosiyana, ndipo mtengo udzakhalanso wosiyana. Kawirikawiri, kusankha kungapangidwe malinga ndi mfundo ziwiri zotsatirazi:
1. Mphamvu:
Kusankhidwa koyenera kwa wattage kumatha kukumana ndi mphamvu zomwe zimafunikira pakuwotcha sing'anga, kuonetsetsa kuti chotenthetseracho chimatha kufikira kutentha kofunikira pogwira ntchito. Kenako, tZotsatirazi ziyenera kuganiziridwa posankha mawerengedwe a madzi:
(1) Kutenthetsa sing'anga kutentha kuyambira kutentha koyamba kukhazikitsa kutentha mkati mwa nthawi yodziwika;
(2) pansi pamikhalidwe yogwirira ntchito, mphamvu iyenera kukhala yokwanira kusunga kutentha kwa sing'anga;
(3) Payenera kukhala malire ena otetezeka, nthawi zambiri ayenera kukhala 120%.
Mwachiwonekere, madzi ochulukirapo amasankhidwa kuchokera ku (1) ndi (2), ndiyeno, madzi osankhidwa amachulukitsidwa ndi malire otetezeka.
2. Kupanga mtengo waliwiro la mphepo:
Kuyeza kuthamanga kwa mphepo, kuthamanga kwa mphepo ndi kuchuluka kwa mpweya kumatha kuchitika ndi chubu cha pitot, manometer amtundu wa U, kupendekeka kwa micro-manometer, anemometer yotentha ya mpira ndi zida zina. Pitot chubu ndi U-mtundu manometer akhoza kuyesa kuthamanga okwana, mphamvu mphamvu ndi static kuthamanga mu chotenthetsera mpweya ngalande, ndi mmene ntchito ya blower ndi kukana kwa mpweya dongosolo akhoza kudziwika ndi kuyeza okwana kuthamanga. Voliyumu ya mpweya imatha kusinthidwa kuchokera ku mphamvu yoyezera mphamvu. Tithanso kuyeza liwiro la mphepo ndi anemometer ya mpira wotentha, kenako ndikupeza kuchuluka kwa mpweya molingana ndi liwiro la mphepo.
1. Lumikizani fani ndi chitoliro cha mpweya wabwino;
2. Gwiritsani ntchito tepi yachitsulo kuti muyese kukula kwa njira ya mpweya;
3. molingana ndi kukula kwake kapena makulidwe amtundu wamakona, dziwani malo oyezera;
4. Tsegulani dzenje lozungulira (φ12mm) pamphepete mwa mpweya pamalo oyesera;
5. Lembani malo oyezera pa chubu cha pitot kapena anemometer ya mpira wotentha;
6. Lumikizani chubu cha picot ndi U-type manometer ndi latex chubu;
7. Pitot chubu kapena otentha mpira anemometer ndi vertically anaikapo mu ngalande mpweya pa dzenje kuyeza, kuti kuonetsetsa kuti malo kuyeza ndi olondola, ndi kulabadira malangizo a pitot chubu kafukufuku;
8. Werengani kukakamiza kokwanira, kuthamanga kwamphamvu ndi kuthamanga kwa static mu duct molunjika pa manometer opangidwa ndi U, ndipo werengani kuthamanga kwa mphepo mumsewu mwachindunji pa anemometer yotentha ya mpira.
