RP-543 -- An Investigation of Freezing Control Strategies for Residential Air-To-Air Heat Exchangers

The objectives are 1) To analytically characterize freeze-control strategies used for residential air-to-air heat exchangers (heat recovery ventilators); 2) To compare the need for, and effect of, various freeze-control strategies on the seasonal thermal performance of residential heat recovery units operating in different climates; and 3) To optimize specific freeze-control strategies and evaluate the associated energy savings.
