I LOVE visiting museums around the world! They are literally time capsules…and nothing inside them ages! My most recent museum visit was awesome. I discovered manuscripts, paintings, and dinosaur bones; it genuinely felt like I was in the actual world of “Jurassic Park,” minus the fear of being chased by man-eating raptors, of course. I have always wondered about museums when it comes to HVAC systems and the design of them. Dinosaur exhibits are my absolute “number one.” I think that museums with dinosaur bones must have an HVAC system designed to preserve numerous collections with meticulous control over the indoor climate. I am sure that not a single person understands the importance of HVAC design and repair any better than museums’ staffs. I can only imagine what would happen if the facility is not sealed and weathertight. Just like in a home, once humidity rises, condensation develops. That’s precisely why I always make sure the dehumidifier on my cooling unit is functioning properly. Condensation would certainly cause artifacts and many other things in the museum to freeze or deteriorate. That truly has to be a museum staff person’s worst nightmare–causing irreversible destruction and hundred- or even thousand-year-old treasures to be destroyed. I suppose that too much moisture on any site could cause quite a bit of damage–not as comparable as in a museum, though. One day, I had a quick conversation with the staff and was told that they raise the temperature and increase the humidity in popular exhibition halls, and that to maintain effective heating and cooling, it must be planned out and applied continuously over one season at a time. Pretty neat!
