[TRNSYS-users] (PLEASE)optimization of a solar heating system combined with dual-source heatpump

[Dr Yi Zhang]

I am not sure if the PSO in GenOpt is a multi-objective algorithm... if not,
you need to set the weighting between the two objectives "right" in order to
get the desired result. Try jEPlus+EA for a multi-objective approach, which
will show you the trade-off between performance and cost:

Seeing  the trade-off will help you answer your second question, too.

 

Regards,

Subject: [TRNSYS-users] (PLEASE)optimization of a solar heating system
combined with dual-source heatpump

 

Dear all

I am now doing a project named "optimization of a solar heating system
combined with dual-source heatpump(dual-source:water in storage tank  and
outdoor air)" in trnsys for my master degree thesis, the system is just used
for space heating in heating season at a high and cold area where the solar
radiation is not so good.The schematic diagram of the system is as follow:



I want to find the best configuration of the system (include the area of the
collectors, the angle of azimuth&dip of the collector, the constant flowrate
of the collectors, the volume of the storage tank ) .when i simulated it in
trnsys and genopt using PSO ,i tried to set the object function as the sum
of  energy consumption in a year or the life circle cost of the system ,it
turned out that the optimised area of collector is awalys to be the low
limit of the collectors range i set in the genopt, may be it is  the truth,i
am confused.

 

another question which is really important to me:

Has anyone has the experience of optimization in similar system?how to
confirm the best area of collector of the system?

any advice is much appreciated.

Ware

best regards
