Heat producing components should be located at the top of the panel for proper heat dissipation. This design is logical and helps with troubleshooting. Starting with the components with the highest voltage levels at the top of the panel and working down from left to right with the lower voltage level components toward the bottom right. If simple components won’t do the job go to programmable logic controllers(PLCs) and any other components required to get the job done.īest practices for HVAC control panel design is to group similar voltage rated components together. For an energy efficient control panel try to use simple components such as relays, switches, etc., they produce less heat and are energy efficient. Inadequate space is one of the most common NEC violations.Ĭomponents should be laid out in a logical manner with attention to power needs and heat dissipation. Make sure you have plenty of room to work between components and plenty of room on the panel. Don’t forget to leave space for expansion both horizontally and vertically. Layout and Component PlacementĪ neat, well-organized control panel starts with a generously sized panel that allows for adequate spacing between voltage groups and individual components.
All components and wire ends are labeled properly, sensibly, and in a method designed to last for the lifetime of the control panel. A completed control panel is logically arranged, easy to troubleshoot, visually pleasing and has adequate expansion room.
A control panel is designed to do two things, provide electricity to the internal components and control an HVAC system. Here is a look at some of the main aspects of creating a well-designed industrial HVAC control panel.
