Comparing HVI and AHRI test results for ERVs
Our project is trying to determine which ERV units will be most efficient for our application, and we’re looking at a variety of ERV products. Some are tested by HVI while others are certified by AHRI. We are struggling to accurately compare the difference between testing results offered by HVI and AHRI. There seems to be very little ability to cross-reference test results, making a comparison all but impossible. What techniques or systems have you found for comparing these two testing standards?
