Our new convection ovens cook evenly, so the hotel kitchen can serve breakfast much faster.

我們新的對流烤箱受熱均勻，讓飯店廚房能更快供應早餐。

The facilities manager explained that convection carries warm air to the upper floors first.

設施經理解釋說，對流會先把暖空氣帶到較高的樓層。

Please confirm the shipment of convection heaters arrives before the warehouse opens next Monday.

請確認那批對流式暖氣機會在下週一倉庫開門前送達。
