【摘要】：基于上海某高校綜合研究中心地埋管地源熱泵工程,對(duì)地源熱泵系統(tǒng)穩(wěn)定運(yùn)行3 a地埋管換熱區(qū)內(nèi)外地溫場進(jìn)行實(shí)際監(jiān)測(cè),并對(duì)3 a間換熱區(qū)內(nèi)外地溫場變化特征進(jìn)行深入分析。分析結(jié)果表明:系統(tǒng)穩(wěn)定運(yùn)行3 a,換熱區(qū)內(nèi)外地溫受地埋管換熱器取放熱影響呈波狀變化,并且地溫變化相對(duì)于環(huán)境溫度的變化存在一定的滯后性,換熱區(qū)中心區(qū)域約滯后3個(gè)月;隨著深度的增大地溫變化幅度有逐步減小趨勢(shì);實(shí)驗(yàn)場地源熱泵系統(tǒng)持續(xù)運(yùn)行3 a地埋管換熱對(duì)地溫的影響半徑半徑為6.0~9.0 m;實(shí)驗(yàn)場在夏季空調(diào)使用高峰采用了地表水地源熱泵系統(tǒng)進(jìn)行調(diào)峰,系統(tǒng)持續(xù)運(yùn)行3 a地埋管換熱器取放熱基本平衡,未造成地層熱堆積現(xiàn)象,運(yùn)行效果較好。
[Abstract]:Based on the ground ground source heat pump (GSHP) project of a comprehensive research center of a university in Shanghai, the ground source heat pump (GSHP) system has been operated steadily for 3 years and the ground temperature field in and out of the underground heat exchange area has been monitored. The variation characteristics of geothermal field in and out of the heat transfer zone are analyzed in depth. The results show that the system runs steadily for 3 years, and the ground temperature inside and outside the heat transfer zone is wave-shaped under the influence of the exothermic effect of the buried tube heat exchanger. Compared with the change of ambient temperature, the variation of ground temperature has some lag, and the central region of heat transfer region is delayed for about 3 months. With the increase of depth, the range of variation of ground temperature has a tendency to decrease gradually. The influence radius of ground source heat pump system on ground temperature for 3 years is 6.0 ~ 9.0 m. The ground water ground-source heat pump system was used to adjust the peak value of air conditioning in summer. The system operated continuously for 3 years and basically balanced the heat release of the ground heat exchanger, which did not cause the formation heat accumulation phenomenon, and the operation effect was better than that of the ground water ground source heat pump system.
