Analysis And Application On Coupling Operation Of Solar Water Heating-Boiling System

The solar water heating and boiling systems with large area were designed and used for central bathing and drinking water project of a university in Zhengzhou. With oil/gas boiler auxiliary heat, the solar water heating-boiling system coupling operation method was investigated. The results show that this coupling operation method can effectively regulate hot and boiling water output in summer and winter by temperature partition, significantly increase the system efficiency to 0.56. The annual COP value is 5.07, energy-saving effect is optimal, and the collector area configuration achieves its optimum. The system has obvious advantages in maintaining water quality, temperature, pressure stability and convenience of operation and reliability.It's running stably.
