the flow of energy in either of these situations could be controlled by creating easily installed “flapper” type diffuser located doors that open with fan generated air flow & close with no fan generated air flow. i believe simple diffuser “flappers” could potentially save folks a substantial amount of money on energy costs. i would love to see if i’m right or wrong.
