IPH Linear: collector and receiver

Hello,

Could you tell me, what the type (model) of collector and receiver in IPH Linear used by default?

Best regards,
Gabriel

Load profile

Hi,

Is it possible to introduce a load profile in Process heat linear direct steam and parabolic trough mode?

Thanks,

Gabriel

Sub-hourly simulation for Linear Fresnel

Dear SAM Team,
we formatted a CSV weather file to run a simulation for Linear Fresnel in sub-hourly basis, like 15 minutes and 1 minute (as we were able to run such simulations for PTC and Power Tower). However, the program took each line in the file as an hourly value, so that we had only 91 "days" for 15 minutes simulation and six "days" for one minute simulations.

azimuth in solar posision mode

Hi
i m facing a problem
HOW SHOULD I USE AZIMUTH ANGLE ?
IS ITS ORIGIN FROM NORTH OR SOUTH? CLOCKWISE OR COUNTER_CLOCKWISE ?

Problem to lunch the applicatiion

Dear all.

I installed the SAM software in Windows, but when I try to open it, an error message appears immediately. I tried to resolve by reinstalling SAM but there are no changes, the same error appears. The error message is: 'the application could not be started correctly (0xc000007b). Click on OK to close it'. Attached you can find a prin-screen of the message.

Thanks.

PTC and LFR

I am doing a performance analysis of physical model parabolic trough and linear fresnel reflector. When I ran the simulation, I found everything fine except the absence of "Plant Efficiency" in the result summary (other results like annual energy, gross to net conversion, capcity factor, and water usage were available). Do SAM automatically provide the value of plant efficiency or I need to calculate it seperately? I am a student and new user of SAM, so help me with this, please.

Parasitic Differenses

Hello Paul, I am comparing two different models (CSP Linear Fresnel Steam and CSP Linear Fresnel (Molten)). The model using molten salts as HTF calculates the amount of electrical power consumed by a single collector tracking mechanism. Why the steam model does not calculate that?

how to use data

Hi! Im begining to use SAM. Im confused whit the data to use in CSP, Im using hourly DNI, and for flat plate collectors hourly GHI, DHI and DIF. Is it right?
Thanks

Linear Fresnel Secondary Concentrator

In the model of "Molten Salt Linear Fresnel," I find that the software dose not has the corresponding input parameter about CPC (secondary parabolic mirror). How to consider the influence of the secondary mirror in the simulation calculation?
