Hi good night, I'm learning to use this program to find the cost of equipment for my PFC.
The fact is that there are two things I do not understand: I do the simulation, everything converges and perfect. I give and evaluate the costs and shows me everything, great ... but:

1) It shows the cost of the 4 heat exchangers and compressor, and puts me ZERO COST to the expansion valve to the mixer and splitter ... why?

2) When I click in tab TEMA Heat exchanger, see that's changed about me exchangers which I put in the simulation ... (put AEL and costs me switch to BEM), this what happens?

Thank you very much
