摘要 本课程设计是关于蒸发式冷凝器的设计，针对蒸发式冷凝器的换热过程同时存在显热和潜热交换，计算过程比较复杂且方法较多的情况，采用一种简单的蒸发式冷凝器的设计计算方法，通过基本参数确定、盘管设计、水系统设计和风系统设计，进行系统设计计算，得出换热量、传热面积、淋水量、水泵功率和风机功率等设计参数，该方法适用于常规蒸发式冷凝器的设计计算。 关键词：蒸发式冷凝器；盘管；水系统；风系统。 Abstract The evaporative condenser is designed. For the heat transfer process of evaporative condenser with latent heat exchange and sensible heat exchange, the calculation method is complex. It has a lot of method for evaporative condenser and a simple practical design calculation method of evaporative condenser is used for the design and calculations of the conventional evaporative condenser. Through the calculation of basic parameters, coil design, water system design and air system design, system design calculations were completed. The quantity of heat transfer, the area of heat transfer, the quantity of spray water, pump power and fan power were calculated. This method is applicable to the conventional design and calculation of the evaporative condenser.
