Isikhokelo sokukhetha imodeli yokuhlala
Ukukhetha ukuhamba komoya:
Okokuqala, ukukhethwa komthamo womoya kunxulumene nokusetyenziswa kwendawo, ubuninzi babantu, isakhiwo sesakhiwo, njl.
Cacisa ngokuhlala ekhaya kuphela umzekelo:
Indlela yokubala 1:
Indawo yokuhlala eqhelekileyo, ngaphakathi yindawo yabantu abangama-85㎡, abantu aba-3.
| Indawo yokuhlala ngomntu ngamnye - Fp | Utshintsho lomoya ngeyure |
| Fp≤10㎡ | 0.7 |
| 10㎡＜Fp≤20㎡ | 0.6 |
| 20㎡＜Fp≤50㎡ | 0.5 |
| Fp＞50㎡ | 0.45 |
Jonga iKhowudi yoYilo lokuFudumeza, ukuVuthela umoya kunye nokuVuthela umoya kwiZakhiwo zoLuntu (GB 50736-2012) ukuze ubale umthamo womoya omtsha. Inkcazo ibonelela ngomlinganiselo omncinci we-air duct (oko kukuthi, imfuneko "encinci" ekufuneka ifezekiswe). Ngokwetheyibhile engentla, inani lotshintsho lomoya alinakuba ngaphantsi kwe-0.5 amaxesha / h. Indawo yomoya esebenzayo yendlu yi-85㎡, ukuphakama yi-3M. Umthamo omncinci womoya omtsha yi-85×2.85 (ubude obucocekileyo) ×0.5=121m³/h, Xa ukhetha izixhobo, umthamo wokuvuza wezixhobo kunye ne-air duct nawo kufuneka wongezwe, kwaye i-5%-10% kufuneka yongezwe kwinkqubo yokuhambisa umoya kunye ne-exhaust. Ke ngoko, umthamo womoya wezixhobo akufuneki ube ngaphantsi kwe: 121× (1 + 10%) = 133m³/h. Ngokwethiyori, i-150m³/h kufuneka ikhethwe ukuhlangabezana neemfuno eziphantsi.
Into enye ekufuneka uyiqaphele, xa ukhetha izixhobo ezicetyiswayo zokuhlala, bhekisa kutshintsho lomoya olungaphezulu kwezihlandlo eziyi-0.7; Emva koko umthamo womoya wezixhobo ngu: 85 x 2.85 (ubude obucocekileyo) x 0.7 x 1.1 = 186.5m³/h, Ngokwemodeli yezixhobo ezikhoyo, indlu kufuneka ikhethe izixhobo zomoya omtsha ezingama-200m³/h! Imibhobho kufuneka ilungiswe ngokomthamo womoya.
