Abstract
The performance of an indirect evaporative cooler provided with a flat plate heat exchanger was studied by simulating its operation in a typ ical building, using the weather conditions of Athens. Simulations wer e performed with the TRNSYS code. The results were the temperatures at the outlet of the cooler and inside the building, the comfort hours a nd the hours of cooler operation per day. The sensitivity of the coole r performance to night ventilation rate and the size of the south wind ow glazing were also investigated. Simulation results showed that the cooler increases the number of comfort hours per day inside the buildi ng, since the indoor temperature is significantly lower when the syste m operates than under free-floating conditions. It was found also that night ventilation increases the comfort hours of the building while r educing the hours of operation of the cooler.
