<p class="MsoNormal"><span lang="EN-GB">Thank you for your answer. I see your point but what doesn’t make sense to me is the fact that I have four airnodes with different cooling setpoints. When I use the Air Side Heat Transfer output from the cooling coils
(Type508) as an input for the cooling power available in three of the airnodes, it works and Qcool is not zero in any of them but it becomes zero (all of them) when I include the fourth airnode.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I have used a plot to compare the Qcool from Type56 and the Air Side Heat Transfer output from the cooling coils and the difference among the airnodes is that in the three which work, as I mentioned in the previous paragraph,
the output from the cooling coil is bigger than Qcool from Type56. However, in the fourth airnode is just the opposite.

<p> What Type56 is reporting in those outputs is the amount of additional energy that must be removed from a zone in order to maintain the setpoint that you have provided. If you give the zone exactly the amount of cooling energy that it needs then the demand
for additional cooling energy is zero.<o:p></o:p></p>
