Very large air-to-air enthalpy recovery exchangers are in common use, with air flow capacities more than 20 times the maximum capacity of the largest independent test facility, testing in accordance with ASHRAE Standard 84. 1799-RP conducted testing to validate the practice of testing a small version of a large exchanger to verify the performance rating of the large exchanger. In addition to standard test conditions, additional points at other temperature and humidity levels were performed to measure the impact on sensible and latent transfer effectiveness. The results of this work are summarized in two presentations.
