【摘要】 通过热力循环的分析,对冷水机组运行中的冷冻水温度和冷却水温度及换热面积和换热系数进行了探讨,并对结构参数的优化进行了讨论。结果表明:冷冻水温度的提高或是冷却水温度的降低能提高冷水机组效率;提高结构参数中数值较小的参数,更能有效地提高机组效率。更多还原

【Abstract】 Based on the theory of thermodynamic cycle, the factors affecting the energy efficiency including thechiller water temperature and cooling water temperature and the heat exchanging area and heat exchanging coefficientwere analyzed, and the optimum of the structural parameters was discussed. The results show that raising the chillerwater temperature or reducing the cooling water temperature can improve the energy efficiency, and raising the smallerbetween the structural parameters can improve the energy efficiency.更多还原
