# 燃气冷热电三联供的设备间通风系统模拟研究Simulation Study on Ventilation System of the Equipment Room for CCHP System

Abstract: Heat dissipation between equipments of CCHP system, which need well organized ventilation to assure the optimum temperature for equipments running. It costs much to obtain the ventilation plan by experimental method; it is necessary to use simulation as an auxiliary for the design of ventilation system. By the building of mathematical model of equipments and using the software Fluent for numerical analysis of the temperature field between equipments, this paper gives the improvement scheme for air distribution mode and design criteria for ventilation. According to the improved ventilation system, the extra use of cold wind equipment can decrease the running temperature of power generator effectively by simulation under the condition that the inlet air temperature is equal to the design temperature 307 K of outside in summer. In winter, when the inlet air temperature is equal to the design temperature 269.4 K of outside, the use of natural air inlet and forced air exhaust can keep the running ambient temperature between equipments, which can save operation costs of the system.
