摘要：【中文摘要】 水環(huán)熱泵系統(tǒng)作為節(jié)能型空調系統(tǒng)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(huán)熱泵聯(lián)合供暖的方式,本文依據(jù)生產(chǎn)廠家提供的技術參數(shù),擬合出空氣源熱泵和水環(huán)熱泵的COP性能曲線,對兩種熱泵聯(lián)合運行供熱時的系統(tǒng)性能系數(shù)COP進行了理論分析并用Maple軟件進行模擬計算,得出聯(lián)合運行系統(tǒng)與單獨采用空氣源熱泵系統(tǒng)相比并不節(jié)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(huán)熱泵; 性能系數(shù)COP【英文關鍵詞】 air-source heat pump; water-loop heat pump; COP
