【摘要】 根据近年来深圳地区夏季气候变迁的特征,通过焓差法和数值积分法试差验算在用冷却塔设备的工况变化,分析设计工况和超设计工况条件下的冷却塔气液比、冷却水温和传递单元数与气候条件的关系,得出满足该冷却塔出口水温θ=32℃的气候条件是t=34℃,φ=0.78,并试差计算该冷却塔在超设计工况运行条件下的冷却水温度。更多还原

【Abstract】 Based on the characteristic of summer weather variance in recent years in Shenzhen region,this paper calculated and examined the working condition change of the cooling tower facility in use by the enthalpy potential method and the numerical integration method.The relationship between the weather condition and air-water radio,cooling water temperature and delivery-unit number of the cooling tower,under design working condition or beyond design working condition were analyzed.The weather condition t=34 ℃ and φ=0.78 for exit water temperature θ=32 ℃ of this cooling tower was obtained based on the analysis results.The exit water temperature of this cooling tower beyond design working condition was calculated by try and error method.更多还原
