Dear TRNSYS users,
Hi,
I am modelling a thermal
energy storage system by using the Type 10 as thermal
storage. As you know, the Type 10 can be charged
by running hot air from the top to the bottom and
discharged by running cold air from the bottom to the top of
the bed.
In my simulation, I am
going to first charge the Type 10 and following which
discharge it. To this end, My initial temperature for the
bed was 10 and with the aid of a fan, I set an entrance mass
flow rate of 100 kg/hr and temperature of 80 degrees Celsius
for the bed.
In addition to this, I
determine a controller in such way when the average
temperature of the bed reaches 70 C (during charging
process), it turns off the fan and sets the flow rate in the
opposite direction to 100 for discharging process.
However, it appears an
error message when the discharging process attempts to
begin.
I would appreciate it if
anyone could assist me in this case.
