There are a number of ways that you can handle this; the most
appropriate one depends a bit on how you are modeling the chiller.
If you are modeling an idealized chiller using a cooling type inside
Type56/TRNBuild then you can schedule the COOLING Type's capacity
using a schedule defined inside TRNBuild. If you are using an
external chiller model such as the air or water cooled chiller from
the TESS Libraries then you can use Type14 to define a forcing
function that has a value of 1 between 7am and 4pm and a value of 0
at other times. The output of the forcing function can then be used
for your chiller control signal. I would caution you on running your
chiller based only on the time of day. Typically chillers are run as
needed in order to maintain a loop temperature (in other words based
on a thermostat). If your chiller operates on both a thermostat and
on a timer then you can combine two output signals by multiplying
one by the other in an equation.<br>
<br>
It is also highly recommended that you follow through the tutorial
in the Getting Started manual so that you get an understanding of
the basic process of putting together a TRNSYS simulation.<br>

<div>hello users.</div>
<div>i m a new users of trnsys. i m modelling type 56 building
and do not know to give the schedule for chiller. my chiller
is ON at 7 A.M. and OFF at 4 P.M. and it repeats every day. i
hope you will help me out from this.</div>
<div>thanks for any help.</div>
