I used a type1270 that we bought a few years ago. I have a number of problems I can`t solve.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>- When I use Type1270b (built-in component) it reports "fatal error in Trnsys" even though the example from the HighRiseWithPCM folder works in Trnsys17 that I have installed on my computer.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>- When I use Type1270a (custom component), the project can be run in Simulation studio, but there seems to be no interaction between the building and the PCM layer. The results indicate that the temperature of the PCM layer is equal to zero during simulation period of one year.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I connected all components as it given in the example HighRiseWithPCM.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>- Also, if I put that the PCM melting temperature is lower than the solidification temperature, simulation in SIMULATION STUDIO can be started. But, if these temperatures are equal or the melting temperature is slightly higher than the solidification temperature (such as for example for coconut oil), then it does not work.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Please help me find what is causing this.
