根据气候条件和建筑负荷特点，蒸发冷却可以替代机械冷却。为了推广这种技术，有几种工具或多或少适用于不同的设计阶段。一方面，IEA附件28工作组制定了定性规则，但这些规则不足以帮助确定蒸发冷却系统是否具有成本效益。另一方面，欧洲的建筑工程师很少使用包含蒸发冷却器模型的建筑模拟程序，这就是为什么需要预先设计的工具来首次估计冷却潜力和不适时间。为了确定与机械冷却系统相比，这些低能系统的成本效益，应该开发更详细、易于使用的设计工具。本文比较了间接蒸发冷却系统和直接蒸发冷却系统的主要模型。 最简化的模型基于蒸发冷却器的恒定效率，无论入口条件如何。它们使用最广泛，适用于预先设计的工具。基于商用蒸发冷却器数据拟合的经验模型也已开发出来。为了增强模型，特别是在非标称条件下，对蒸发冷却器采用了使用传热传质基本方程的理论方法。然而，这些方法通常需要（尤其是间接系统）大量的几何数据，这些数据不容易收集。更简单的模型源自理论，仅从一个标称额定点进行参数化。通过对蒸发冷却模拟模型的文献回顾，介绍了两种工具:一种简化的预设计工具，该工具在给定室外温度和湿度比的情况下确定每个系统的供应温度。它决定蒸发冷却系统何时能够提供必要的供应条件。 该工具直观地向用户显示蒸发系统是否可以使用以及可以使用多少小时，并计算夏天的不适时间。结果和两个案例研究的讨论被提出。一个更详细的设计工具建模直接和间接蒸发冷却系统。该程序从理论推导而来，每小时模拟一次，估计每年的水和能源消耗以及任何室外条件下的室内空气条件。它被开发成处理空调能耗的软件的一部分。单元:SICitation:研讨会论文，佐治亚州亚特兰大，2001年

Evaporative cooling can be an alternative to mechanical cooling depending on climatic conditions and building load characteristics. To promote this technique, several tools are available that are more or less suitable at different design stages. On the one hand, qualitative rules have been set by the IEA Annex 28 working group, but they are insufficient to help decide if an evaporative cooling system is cost-effective. On the other hand, building simulation programs, incorporating evaporative cooler models, are rarely used by building engineers in Europe, which is the reason why there is a need for pre-design tools giving a first estimation of cooling potential and hours of discomfort. More detailed design tools that are easy use should be developed in order to determine the cost-effectiveness of these low energy systems compared to mechanical cooling systems. In this paper, principal models of indirect and direct evaporative cooling systems are compared. The most simplified models are based on a constant efficiency of evaporative coolers whatever the inlet conditions. They are the most widely used and are adapted for pre-designed tools. Empirical models, based on the fitting of commercial evaporative cooler data, have been developed as well. To enhance the models, particularly for non-nominal conditions, theoretical approaches using fundamental equations for heat and mass transfer have been carried out for evaporative coolers. However, these methods often require (particularly for indirect systems) a large amount of geometrical data, which are not easy to gather. Simpler models are derived from theory and are parameterized from only one nominal rating point. From a literature review of evaporative cooling simulation models, two types of tools are presented: A simplified pre-design tool that determines the supply temperature for each system given the outdoor temperature and humidity ratio. It determines when evaporative cooling systems can provide the necessary supply conditions. This tool visually shows the user if and for how many hours the evaporative system can be used and computes the discomfort hours in the summer. Results and discussion of two case studies are presented. A more detailed design tool modeling direct and indirect evaporative cooling systems. This program, derived from theory, estimates the yearly water and energy consumption and the indoor air conditions for any outdoor condition in a hourly simulation. It was developed to be part of software dealing with air-conditioning energy consumption.Units: SI
