hello, r u using collectors in series of parallel?

in TRNSYS you need to give flow in total,,for total area of collectors. in TRNSYS also need to define the collectors in series or parallel.

We can define collectors in series. How to define in parallel??

when collectors are in series with default value of one...it means its parallel. (the solar collector model can simulate an array of identical solar collectors hooked up in series. This parameter is used to specify how many collectors are hooked up in a series arrangement where the output of the first collector is the inlet to the second collector).

Thank you sir

Then how to determine flow rate through collector?

Flow rate of a collector is given by manufacturer. If flow rate is 40 kg/hr.m2 and 2 collectors are connected in series. If area of a collector is 1m2 then you will specify 40 kg /hr in the pump. If both are connected in parallel then flow rate will be 80 kg/hr, 40 kg/hr for each collector.
