五星酒店對暖通的要求集中體現在：系統運行的可靠性要高；室內的舒服度要高；系統要實現節能運行。設需要注意以下幾方面的問題：不同的酒店管理集團有不同的設計標準，例如某酒店的室內空調設計標準：五星酒店客房的夏季、冬季設計溫度分別為24℃、22℃，其它房間的室內設計標準也都比較高，負荷計算時應按照酒店管理集團的標準進行（往往設計院認為不滿足設計規范要求，但對于五星酒店審圖不會卡這個）。

The requirements of five-star hotel for HVAC are mainly reflected in: the reliability of system operation should be high; Indoor comfort should be high; The system shall realize energy-saving operation. Attention should be paid to the following aspects during design: different hotel management groups have different design standards, such as the indoor air conditioning design standards of a hotel: the design temperatures of five-star hotel rooms in summer and winter are 24 ℃ and 22 ℃ respectively, and the indoor design standards of other rooms are also relatively high. The load calculation should be carried out in accordance with the standards of the hotel management group (the design institute often thinks that it does not meet the requirements of design specifications, but it will not be stuck for the drawing review of five-star hotel).
