Adjusting IDF motor pulley to FLA ratings of RTU
Hello,
For years I've adjusted IDF motor pulleys to the FLA ratings of the blower motor with the theory of I'm loading my evap coil up more and getting the system to its peak performance. I've had techs tell me I was incorrect with this but never offer any true explanation as to why. So am I right with doing this and making an improvement in the system, or am I incorrect in doing this? The systems work fine when I do this with no complains, I just felt I was making a system better by doing so. I know I wont dehumidify as well increasing my airflow over the evap coil, but I felt I am loading the coil up more, hence removing more heat from the space. I just want to have some educated opinions on this... Thanks...
