| Abstract: | Closed cooling tower is widely used in large water cooling air conditioning system,and its efficiency has great influence on COP of air conditioning unit.In order to analyze the influence of structure and operation parameters on the cooling performance of evaporative closed cooling tower,the heat transfer mechanism inside the cooling tower was analyzed,and a mathematical model of coil heat and mass transfer was established.The research variables were selected and the research conditions were determined.The mathematical model was calculated by using Matlab to change a single parameter,and the influence trend of the change of structure and operation parameters on the cooling water outlet temperature and cooling efficiency was obtained,which provided theoretical guidance for the structure and operation design optimization of closed cooling tower. |
| Keywords: | Evaporative closed cooling tower Cooling performance Matlab Structural parameters Operating parameters |
