基于相似系数法的冷源供水温度研究

Study on water supply temperature of cooling source on similarity coefficient method

针对中华鲟保育池冷冻水系统冷源设备选型采用经济性或生态因子进行单因素比选的不足,通过相似系数法对保育池不同水温工况下的经济性和生长影响因子赋予权重,提出了统筹经济指标和生长影响因子指标的综合评价指标。分析结果表明,21℃为保育池冷冻水系统最佳供水温度,不仅满足中华鲟生长对水温的要求,经济性也较好。将基于相似系数法的权重确定方法应用于保育池冷源供水温度的比选,提高了比选的客观性,对其他涉及主观性评价指标的方案比选具有一定的借鉴意义。

Aimed at the shortage of single factor comparison and selection by economic or ecological factors in the selection of chilled water system cold source equipment in Chinese sturgeon conservation pool,the economic and ecological factors under different water temperature conditions were given weight by similarity coefficient method,and the comprehensive evaluation index of overall economic index and ecological factor sub index was proposed.The results show that 21℃is the best water supply temperature for the chilled water system of the conservation pond,which not only meets the requirements of water temperature for the growth of Chinese sturgeon,but also has good economy.The weight determination method based on the similarity coefficient method is applied to the comparison and selection of cold source water supply temperature of nursery pond,which improves the objectivity of comparison and selection,and has certain reference significance for other schemes involving subjective evaluation index.
