AW: Chilled water system

Dear Choong Chee Hoong,

for using the outlet air conditions of the cooling coil as inlet
conditions of your zones you have to define temperature, relative
humidity and airchange of the ventilation types (in your building) as
inputs. As ventilation types require the airchange and not the mass flow
rate as an input I would suggest to calculate the airchange in an
eqaution and connect it to the input the appropriate ventilation type.

I have no idea about the mathlab coupling...

Kind regards,

Betreff: Chilled water system

Dear all,

Now I am trying to connect the chilled water system to
the multizone building(type 56) but I have no idea how
to do it. The multizone building do not have any input
option to receive cooled air from the cooling coil. I
have attach the my program to this email, can anyone
help me to check my program please?

My second question is how to link trnsys with matlab?
I have downloaded the trnsys-matlab link component
from internet but there are some error when i try to
run the sample. Can anyone help me on this please?

I need to solve this problem quite desperately. I
really appreciate if anyone can reply this email as
soon as possible. 

Thank you.
