The company's Model RH350 SuperHeat psychrometer features a large displays which allows for the simultaneous display of three parameters: rh with ambient air temperatures, dewpoint or wetbulb, and external temperature. Incorporating the inputs from two external Type K probes, T1 and T2, differential measurements can be displayed as T1-T2, air temperature-T1, and T1-dewpoint. Th large LCD provides an easily readable display of switchable temperatures units (°F or °C) with 0.1-degree resolution.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
