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 On 2/10/2015 10:30, safone samsuddin
