Mohammad,
The simplest way would be to define two equations one of which has
a value of 1 during the time period when you want to allow cooling
and the other of which has a value of 1 during the heating time
period. For example:
isSummer = AND(GT(TIME,3000),LT(TIME,5000))
isWinter = 1-isSummer
You then connect the result of these equations to the appropriate
heat pump inputs. The above equations would allow cooling between
hour 3000 and 5000 of the simulation and would allow heating at all
other times. You have to be a bit more careful with your equation if
you want to run multiyear simulations.
kind regards,
David

dear all ;
how can i control run
this circled heat pump to work on heating mode in winter and
cooling mode in summer.

Hi Jakob,
Thank you for your prompt response.
Unfortunately, both the
restaurant and the sunspace
examples use Type 15-6 and Type 15-2 (TMY-2).
My problem is that when I replace to Type 15-1
(TMY), my heating demand is increased, but
remains within the BESTEST range, while
my cooling demand is significantly below the
BESTEST results. That's how I concluded that
most probably I am doing something wrong in the
connection of the weather file and the solar
radiation available in the building's surfaces.
Thank you for your help anyway.
Kind Regards,

Dear Eirini,
you can find an example
in your TRNSYS directory under
…\Examples\Restaurant\Restaurant.tpf
It also uses types 15 and
56…
Best regards

Question on Type 15-1 (TMY Weather
file)
Hello TRNSYS Users,
I am trying to simulate a
simple building (BESTEST Case
600) and I am getting quite odd
results. I believe that my mistake
is in the connection between Type
15-1 (TMY Weather file) and Type 56
(Multi-zone building). I would like
to ask whether there is any tutorial
online or any example in the
program's documentation folder on
how to connect weather files to Type
56 for multi-zone building
simulation.
Thank you.
Kind Regards,
Eirini
