many solar collector systems have two pumps . the main solar circle
pump, which causes an flow rate over the heat exchanger and the starting
circle pump ,
which causes an flow rate over an bypass pipe . So the starting pumps
starts , if the temperture difference(1) is big enough. if the
temperature in the bypass pipe is
nearly the collector out temperature (controlling temperature difference
2) , the solar circle pumps starts, and the starting pump should stop.
So if the temperture difference (1) is lower x ,than the solar pump
So the controling difference is the start condition for the first
pump,and the stop condition for the second pump.
What is your solution for this ,and does it make sence to simulate this.
