<p class="MsoNormal"><span style="color:black">Hello everyone,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">I currently try to use Type 123 Cooling Coil with TRNSYS18. Type 123 is directly connected to the TRY2017 weather data reader. All other inputs to Type 123 are considered to be constant.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">The rated parameter values are measured values and do not include any dehumidification.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><img width="608" height="263" style="width:6.3333in;height:2.7395in" id="Grafik_x0020_1" src="cid:image002.jpg@01D53BD9.1876F990"><span lang="EN-US" style="color:black"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">No matter whether I use humidity mode 1 or 2 and no matter whether I reduce the total cooling capacity to e.g. 400 kJ/hr I always get the following error: “The referenced Unit has a bad parameter value.
Reported information: Parameter #7, Reported Problem: The total cooling capacity of the coil is impossible at the given conditions.”
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">And an additional warning message is shown: “The referenced Unit has called the PSYCHOMETRICS routine one or more times during the simulation with a humidity ratio above the saturation humidity ratio
for the given dry bulb temperature. The air was assumed saturated at the given dry bulb temperature and the humidity ratio set for this condition.”<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">I already checked the connection between the weather data reader and Type 123. I also tried a simulation with constant input values…..there is still not difference.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">Thus I think it is a bug in Type 123 or the psych subroutine.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:black">Does anyone have a solution or an idea what could cause the errors? Thanks a lot for any help!<o:p></o:p></span></p>
