Revision history [back]

I've looked at several examples and tried the setup suggested here (shown below) and several similar versions, including the DOAS/WSHP measure which creates a similar setup, and tried it with dual setpoints.

However, regardless of the method, the loop temperature does not stay within the range I specify (62-88 deg. F). The results below are from 5 zone example file that I used to test the system.

Am I missing a component, or does anyone have a setup that works better for this system type?

However, regardless of the method, the loop temperature does not stay within the range I specify (62-88 deg. F). The results below are from 5 zone example file that I used to test the system.

I also tried running the boiler and cooling tower in series with dual setpoints, per the post here.
This seemed to fix the min. condenser temperature but not the max., and the loop temperatures increased significantly. Again, I tried with and without bypass, the cooling tower in series with bypass, various control strategies for the boiler, etc. But the results were all similar.

In the image below, the temperatures are after the boiler are in orange, and after the cooling tower are in blue.
