[TRNSYS-users] Type 917 AWHP error

[David BRADLEY]

Safwan,
   The Type917 example shows how a house can be cooled while heating a 
tank of water. It isn't really appropriate to run the example in the 
winter. In the climate used in the example, the house requires a 
significant amount of heat. At first the water tank is cooled down to 
provide heat to the house but the capacity of the heat pump is such that 
it cannot provide as much heat as the house requires. The house 
temperature falls and psychrometrics warnings begin to be generated. 
Once the limit on warnings is reached the simulation stops. The example 
is not intended to model a complete, realistic system but to show how 
Type917 might be connected as part of a system.

   If you intend to call Matlab as part of a TRNSYS simulation, you can 
use Type155. You simply need to make sure that the version of 
Type155.dll (located in the ..\Trnsys17\Exe directory matches your 
version of Matlab). Type155 was developed to communicate with Matlab 
releases 13, 14, and more recent. I am not sure whether it is compatible 
with earlier releases. For additional information, please refer to the 
Type155 section of the 04-MathematicalReference.pdf manual.
regards,
  David
