University HVAC systems are weird. We had a steam valve stick open in our building one summer. Brought the internal temperature up to 95. Apparently the chillers bring them temp down to 55F to condense the humidity, then they reheat to 74F. I would not have thought that steam was required for proper AC
- quickthrowman 3y agoSteam isn’t required, electric reheats can manage humidity just fine.
- wombatpm 3y agoIt was the University of Minnesota. They had a big steam plant for heat in the winter
- quickthrowman 3y agoCool! I’ve been in the St Paul campus steam tunnels :) The U of M also has district cooling on both campuses and an east bank steam plant. When you have district heating, it makes sense to use steam for the reheats instead of electrical resistive heaters. There are also steam powered chillers, for places that don’t have district chilled water.
- iamthemonster 3y agoSteam is highly economical as a heat transfer medium if you already have a boiler with plenty of capacity. It's versatile and packs an incredible punch - you need very little heat exchanger area if you're condensing steam on one side.
