In the airport this week heading to training in Boston ✈️ looking up for HVAC equipment as usual…. QSTN - does anyone know more about these units pictured, and/or work in airports? This is a customs office section in YYZ. To me I see a headers/mains piping which must come from a main heating/chiller plant. There then appears to be “unitary”…units, for each section/room which would be controlled by individual thermostats? Any input is appreciated! 🔥⚙️❄️
