| Abstract: | Based on the theory of thermodynamic cycle, the factors affecting the energy efficiency including the
chiller water temperature and cooling water temperature and the heat exchanging area and heat exchanging coefficient
were analyzed, and the optimum of the structural parameters was discussed. The results show that raising the chiller
water temperature or reducing the cooling water temperature can improve the energy efficiency, and raising the smaller
between the structural parameters can improve the energy efficiency. |
