摘要：作者：趙金玲; 鄒平華 關(guān)鍵詞：暖通空調(diào)論文,生活給水,小時(shí)變化 【中文摘要】 小時(shí)變化系數(shù)Kh是計(jì)算集中熱水供應(yīng)系統(tǒng)設(shè)計(jì)熱水流量及耗熱量的一個(gè)重要參數(shù)。從定義和數(shù)值兩方面對(duì)國(guó)內(nèi)外的小時(shí)變化系數(shù)進(jìn)行了研究分析。指出科學(xué)地測(cè)定各類熱水用戶的用水情況對(duì)于形成和完善適合我國(guó)自己的各種熱水供應(yīng)定額、小時(shí)變化系數(shù)等基礎(chǔ)數(shù)據(jù)體系具有深遠(yuǎn)的意義?！居⑽恼?The coefficient of variation per hours is an important parameter to calculate hot water flow rate and heat consumption in a centralized hot water supply system design. The article analyzes the research findings home and abroad on the coefficient of variation per hours. And it indicate scientifical determination about use of water by various types of water users is profound for the formation and perfection of fixed hot water supply and the coefficient of variation per hours suited to China's.【中文關(guān)鍵詞】 生活給水; 小時(shí)變化系數(shù); 設(shè)計(jì)流量【英文關(guān)鍵詞】 water supply; the coefficient of variation per hours; design flow
