Collector Models for TRNSYS
TRNSYS is a quasi-steady system-simulation code that calculates energy flow and fluid state points for steady flow in an arbitrary set of components (such as collectors, pumps, valves, tanks, etc.) in response to slowly varying boundary conditions (solar insolation and ambient temperature). The time interval is arbitrary, but it should generally be large compared to […]
INFORMATION ON MODELS
7.1 Collector-Subsystem Models for MINSUN A primary objective of the work of Subtask 1(b) was to provide reliable performance and cost models for use in system-optimization studies using the MINSUN system-optimization code developed by Subtask 1(a) for the Task VII studies. Tables 2.4-2.6 and 2.8 constitute the basis for the performance models developed for use […]
