摘要：【中文摘要】 在兩套管路特性基本相同的冷卻水系統(tǒng)和兩臺相同型號的冷卻水泵上,分別進行水泵變頻調(diào)速改造和更換小水泵改造方案的運行試驗測試。試驗結(jié)果表明,兩種方案均有明顯的節(jié)能效果,但是更換小水泵改造方案效果更佳。 【英文摘要】 The modifications with frequency conversion speed regulation and replacing a smaller pump are done for the pump of a water cooling system.Testing results show that each modification has obvious energy saving effect.But the second mothod i.e.replacing the smaller pump,performs better. 【中文關(guān)鍵詞】 中央空調(diào)系統(tǒng); 水泵改造; 節(jié)能; 變頻調(diào)速【英文關(guān)鍵詞】 central air-conditioning system; pump modification; energy saving; frequency conversion speed regulation
