Njira Yopangira
DIN 17175 St45.8 mapaipi achitsulo osasunthika amatha kupangidwa ndi kugudubuza kotentha, kugudubuza kozizira, kukanikiza kotentha, kujambula kotentha kapena kujambula kozizira.
Mapaipi achitsulo amatha kusungunulidwa pamalo otseguka kapena ng'anjo yamagetsi molingana ndi njira yowombera mpweya, ndipo zitsulo zonse ziyenera kuponyedwa mokhazikika.
Kupezeka
17175 St45.8 chitoliro chopanda chitsulo chidzaperekedwa ndi chithandizo choyenera cha kutentha.Chithandizo cha kutentha chimaphatikizapo:
- Kukhazikika.
- Kuwongolera.
- Kutentha;kuchokera ku kutentha kozimitsa, sikuzizira, koma kupsa mtima.
- Sinthani misa ndi njira yosinthira isothermal.
