Pre-design and design tools for evaporative cooling.

Author(s) : STABAT P., MARCHIO D., ORPHELIN M.

Summary

From a literature review of evaporative cooling simulation models, two types of tools are presented: 1/ 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. 2/ A more detailed design tool modelling 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.
