Experimental Determination of Ventilative Cooling Energy Savings: Final Report

摘要

This report summarizes the results of side by side testing of two identical rooms in the FSEC Passive Cooling Laboratory to experimentally determine the energy savings from ventilative cooling and to obtain high quality data for validating moisture algorithms. The test results confirmed that ventilative cooling does save appreciable (30% to 35%) cooling energy. One important finding was that the penalty for introducing humid nighttime air into the room had a rather small penalty (typically between 2% and 5%) on the next day's air conditioning energy use. Room moisture capacitances were also determined from the data. Depending on room operating conditions, it was found that this furnished room had a moisture capacitance somewhere between 3 and 6 times the room air mass. High quality data was obtained which would permit validation of ventilative cooling energy savings algorithms in the future. (ERA citation 12:026615)
