The Science Museum of Minnesota, one of the most visited museums in the upper Midwest and a national leader in providing informal science, technology, engineering, and mathematics (STEM) education, invested in a more sustainable solution after learning that building upgrades could save millions of dollars in energy costs by decreasing fossil fuels and high-energy sources coming from their building.
Dew point is one example of a very useful measurement to understand, design for and test for in an HVAC/R system. Take an evaporator coil, do you know how to calculate the exact temperature at which that evaporator coil will start to condense moisture? can you tell the exact temperature at which a surface inside of a space will start to condensate and possibly grow mold? These are both cases where a basic understanding of a psychrometric diagram can help a technician.
