| 2021-09-22 04:09:41 -0500 | marked best answer | Modify effectiveness in rotational HeatExchanger:AirToAir:SensibleAndLatent I have a project where I would like to change the effectiveness of my heat wheel. I am using Supply Air Outlet Temperature Control and in summer months when the outdoor temperature rises the effectiveness of the wheel drops ( in reality the RPM of the wheel would be changed to reduce effectiveness and thus provide lower temperature) I need some help with two problems: 1) How to change the effectiveness as the rotational speed changes. 2) For a given rotational speed, how to make the effectiveness a parabolic, rather than a (presumably) linear, function of airflow. Can I access the rpm as a variable controllable by EMS ? ( how ? in that case) Can I change the effectiveness as a function of airflows in stead of defining effectiveness at 100 and 75 % airflow rates( on my experience the effectiveness is not a linear function) thanks for any help! |
