Re: [TRNSYS-users] Cooling?

[David Bradley <bradley@tess-inc.com>]

Myting,
  The Type56 output called QSENS is a positive value when there is a 
cooling load and a negative value when there is a heating load in a given 
zone. QCOOL and QHEAT are the same loads but are split apart so that 
heating load is not a negative number. At any point in time during which 
there is a cooling load QSENS and QCOOL should be equal. At any point in 
time during which there is a heating load QSENS should be the negative of 
QHEAT.

no it will not. You need to provide the coupling air flow both from zone A 
to zone B AND from zone B back to zone A. If you need a Type to compute the 
amount of airflow, you can use Type157 (calling COMIS), Type97 (calling 
CONTAM) the proformas for which are located in the Utility: Calling 
External Programs directory in the TRNSYS Studio. Alternatively you can use 
TRNFLOW.
Kind regards,
 David
