[TRNSYS-users] Solar wood dryer

[Jeff Thornton]

<I work on a project of a conception of a solar wood dryer and i
have a problem with the control of the temperature. My aim is to
maintain the cold-side outlet temperature of a heat exchanger water/air
at a constant value. It is connected to a stratified storage water tank
that the profile of the temperature of its top is variable due to the
fluctuation of the solar radiation.> 

The Type 670 heating coil in the
TESS HVAC Library does exactly as you suggest - maintains a given
air-side outlet temperature by varying (bypassing) the hot, liquid side
flow rate around the heat exchanger.

have thought that the control of the water outlet flow of the tank could
solve the problem, but i didn't find the appropriate components to
simulate this test.
