[TRNSYS-users] I need type 538 documentation

[Jeff Thornton via TRNSYS-users]

Ahmad,

The models are different in 3 primary ways:

1) 538 has the ability to consider the mass of the collector.  

2) 538 has a more rigorous solution algorithm that gives much better solutions at low flow rates, low solar radiation, etc.

3) 538 allows you to put the collector in temperature seeking mode and specify a desired output temperature from the collector.
