[TRNSYS-users] Example Type 4 to Type 56 connection

[Jeff Thornton]

TRNSYS does it's best to emulate real-world systems.  So if you had a 
tank full of hot water in real life and wanted to heat your room, how 
would you do it? Therein lies your answer.  Short of spraying the hot 
water into the room (not advised), you could pump the hot water to a 
radiator and heat the room, you could pump the hot water to a fan coil 
unit and blow air across the coil and into the room (called 
ventilation), or you could pump the hot water to a radiant floor.  All 
systems would then return the cooled water back to the tank - unless 
your spraying the water into the room which is still not advised...  So 
if in the real world you would need a pump, pipes, a controller and a 
fan coil to heat the room, in TRNSYS you'll need a pump model, 
controller model, a pipe model and a fan coil model to heat the modeled 
room.
