Cov FAQ
Kuv puas tuaj yeem zam cov kev nkag mus rau nws?
SaumSawv -} rab yaj hlau, Yog {-} siv team clamps. Ntawm lwm lub ru tsev, koj yuav tsum tau flashed genetrations; Qee lub ru tsev tiaj tus tso caipobracks (hnyav dua, xav tau cov qauv kos duab).
Yuav ua li cas thiaj li yuav tsum huam panels lub ru tsev?
Tsuas yog txaus rau airflow thiab dej ntws thaum minimizing cua profile - feem ntau25-100 hli, ib qho kho vajtse thiab huab cua.
Ua cov panels tau nce qhov nyob tom qab?
