Re: [TRNSYS-users] Type10 Rock Bed Storage Inquiry

I'm using TRNSYS-18. Yes, the entire average temperature of the rock bed is changing. I'm not sure but could this might be a phenomenon for small rock beds (total volume < 1m3)? See attached photos for example.

Hello, 

In Type 10 rock bed storage, why is it that when the number of derivatives/segments is increased, the time it takes to heat up the rock bed is faster? The difference between the segment = 5 and the segment = 40 is drastically different for small rock beds. 

Thanks
