This HVAC equipment is located in the classroom. The operation of HVAC systems under various conditions can be demonstrated. One item that can be demonstrated very clearly with this is how a HVAC will malfunction if the right size piping is not used throughout the system.
The photos in this slide show were taken in the mid-1990's by Steve Grande on his Amtrak travels throughout the nation. The size of the photos is purposely smaller as disk space was expensive and download speeds were slower at that time.
