Chigawo chapakati: Watt (W)
Chigawo chapadziko lonse lapansi chosinthira kutentha (chomwe chimatchedwanso kutentha) ndi watt (W). Ichi ndiye gawo lodziwika bwino komanso lokondedwa kwambiri pazamalonda apadziko lonse lapansi, kuwonetsetsa kumvetsetsana kosasinthika pakati pa mabizinesi apadziko lonse lapansi.
1. Tanthauzo Lamagawo:Watt imodzi imafanana ndi joule imodzi pa sekondi imodzi (1W=1J/s), womwe ndi kuchuluka kwa kutentha komwe kumatumizidwa kudzera pa chipangizo chosinthira kutentha pa nthawi iliyonse. Mwachitsanzo, kutentha kwa kutentha kwa 5000W kumatanthauza kuti akhoza kusamutsa ma joules 5000 pa sekondi imodzi.
2. Commonly Used Multiples of Units: Chifukwa cha kusiyana kwakukulu kwa kutentha kwa kutentha m'mafakitale, ma multiples a mayunitsi amagwiritsidwa ntchito kawirikawiri. Izi zikuyenera kuwonetsedwa bwino m'makalata amalonda apadziko lonse lapansi:
- Kilowatt (kW): 1 kW=1000 W, yoyenerera zosinthira kutentha zing'onozing'ono ndi zapakati-monga zosinthitsa kutentha m'nyumba zapanyumba, zoziziritsa kukhosi zing'onozing'ono), ndipo ndi gawo lomwe amagwiritsidwa ntchito mobwerezabwereza pazamalonda zapadziko lonse lapansi ndi matebulo a parameter.
- Megawati (MW): 1 MW=10⁶ W, yoyenera zida zamakampani akuluakulu (monga makina opangira magetsi opangira magetsi ndi zosinthira kutentha kwamankhwala), zomwe zimagwiritsidwa ntchito kwambiri-pamabizinesi akuluakulu komanso mapangano aukadaulo.
. Magawo Omwe Amagwiritsidwa Ntchito M'magawo / Mafakitale Ena
Misika ina yakunja kwa nyanja (monga North America ndi mafakitale ena akale ku Europe) angagwiritsebe ntchito-mayunitsi akunja; Chifukwa chake, ndikofunikira kumvetsetsa maubwenzi otembenuka kuti mupewe zolakwika zolumikizana:
1. Magawo a Imperial: mayunitsi amafuta aku Britain paola (BTU/h)
- Tanthauzo: 1 BTU/h ikuyimira kusamutsidwa kwa 1 British thermal unit of heat pa ola ndipo ndi gawo lomwe amagwiritsidwa ntchito kwambiri ku North America HVAC ndi mafakitale opangira firiji.
- Ubale wotembenuka: 1 BTU/h ≈ 0.293 W, 1 kW ≈ 3412 BTU/h (Iyi ndi njira yosinthira zinthu zamalonda zapadziko lonse lapansi ndipo ikufunika kuloweza pamtima).
- Kagwiritsidwe ntchito kake: Mukamalankhulana ndi makasitomala aku US ndi Canada zokhudzana ndi zoziziritsira mpweya zing'onozing'ono ndi zoyatsira pampu yotenthetsera, m'pofunika kupereka mayunitsi a W (kapena kW) ndi BTU/h nthawi imodzi kuti zikalata zigwirizane.
2. Ma kilocalories pa ola (kcal/h)
- Tanthauzo: 1 kcal/h ikuyimira kusamutsa 1 kilogalamu ya kutentha pa ola. Chigawochi chinkagwiritsidwa ntchito kwambiri ku Ulaya, Japan, South Korea, komanso kumayambiriro kwa mafakitale apakhomo, ndipo chikugwiritsidwabe ntchito m'mafakitale ena masiku ano.
- Ubale wotembenuka: 1 kcal/h ≈ 1.163 W, 1 kW ≈ 859.8 kcal/h.
- Momwe mungagwiritsire ntchito: Mukamagwira ntchito ndi makampani amankhwala azikhalidwe zaku Japan, South Korea, ndi Eastern Europe, ndikofunikira kulingalira ngati ali ozolowera kugwiritsa ntchito miyeso iyi. Ndibwino kuti muphatikizepo mafotokozedwe otembenuka muzolemba zamakono.
Zofunikira pakugwiritsira ntchito Unit
Kuyika patsogolo kugwiritsa ntchito mayunitsi okhazikika padziko lonse lapansi
M'makontrakitala amalonda akunja, mapepala a parameter, ndi zolemba zamalonda, ikani patsogolo kugwiritsa ntchito ma watts (W) ndi ma multiples ake (kW, MW). Mayunitsi omwe si-apadziko lonse lapansi angagwiritsidwe ntchito ngati uthenga wowonjezera, koma pewani kuwagwiritsa ntchito ngati gawo lalikulu poletsa zolakwika pamakotedwe ndi kusankha kwazinthu chifukwa cha kusiyana kwa mayunitsi.
Nenani momveka bwino maziko otembenuka
Ngati kasitomala apempha kuti agwiritse ntchito-mayunitsi akunja, njira yosinthira iyenera kuwonetsedwa mu chikalatacho kuwonetsetsa kuti mbali zonse ziwiri zikumvetsetsa bwino momwe zimagwirira ntchito (mwachitsanzo, "Kutentha kwa chipangizochi ndi 5 kW, pafupifupi kufanana ndi 17060 BTU/h").
Kusiyanitsa pakati pa "kusinthana kwa kutentha" ndi "coefficient yosinthira kutentha"
Pewani chisokonezo cha mayunitsi-chigawo cha kutentha ndi W (mphamvu/nthawi), pamene yuniti ya koyefifi yotengera kutentha (K mtengo) ndi W/(m²·°C). Mawu awiriwa amafotokoza "kutengera kutentha kwathunthu" ndi "kutentha kwa kutentha pagawo lililonse," motsatana, ndipo akuyenera kuzindikirika bwino pakulumikizana kwamayiko akunja.
Ngati mukufuna kudziwa zambiri za mayunitsi osinthira kutentha kapena mukufuna kugula, chonde tumizani imelo kwa9988xiaoshuai@gmail.com, tidzakuyankhani pakapita nthawi titaona uthengawo!
