摘要：【中文摘要】 水環熱泵系統作為節能型空調系統的一種形式,近年在中國得到較多應用。對于近年有些工程提出了采用空氣源熱泵作為熱源與水環熱泵聯合供暖的方式,本文依據生產廠家提供的技術參數,擬合出空氣源熱泵和水環熱泵的COP性能曲線,對兩種熱泵聯合運行供熱時的系統性能系數COP進行了理論分析并用Maple軟件進行模擬計算,得出聯合運行系統與單獨采用空氣源熱泵系統相比并不節能的結論。 【英文摘要】 Water loop heat pump systems are considered as the energy-saving air-conditioning form and have been popular in China in recent years.There are some projects now using air-source heat pumps as the heat source of water loop heat pumps in winter.This paper fitted the COP performance curves of both air-source heat pumps and water loop heat pumps based on the manufacturer's technical parameters,then discussed the COP performances of the co-operating system of the two heat pump heating system and made use of Maple software to analyze this process.The conclusion was that the performance of co-operating of two systems is not energy-saving as compared with the air source heat pump only. 【中文關鍵詞】 空氣源熱泵; 水環熱泵; 性能系數COP【英文關鍵詞】 air-source heat pump; water-loop heat pump; COP
