I have a simple airloop as shown below:
If Outdoor DB Temperatures are too low, then the Outdoor Air Flow should be set to zero. Accordingly the minimum OA Flow rate has been set to 0 m³/s. See here:
Nevertheless, in the following chart you see that outdoor air flow at the outdoor air IN node never reaches zero, but apparently reaches a minimum greater than zero, the origin of which is totally unclear:
Can anyone explain what the reasons might be and how to enforce zero outdoor air flow when outdoor air is too cold ?
