Hello all,

I try to simulate the area, it installs radiant cooling and a water coil that feeds cool water from the air cool chiller. I set each loop in openstudio then export and simulate it as an idf file.

The loop includes: 1. Air cool chiller connect with CHW Coil loop and Fluid-to-Fluid HX loop as a picture https://www.linkpicture.com/q/Chiller... 2. CHW Coil loop as a picture https://www.linkpicture.com/q/Coil-wa... 3. Radiant loop as a picture https://www.linkpicture.com/q/Radaint...

After I simulate on the energyplus idf file, I check the inlet/outlet temperature and flow rate of the water in each node at the radiant loop (please see the picture link).

The Inlet Temperature is 15 C but the outlet temperature is 15 C so I check the water flow rate at node 28 and node 29 is 0.572 kg/s but the water flow rate at node 22 and node 30 is 0 kg/s. I don't know why node 22 and node 30 is 0 kg/s I try to solve it but now I can't do it. please suggest to me about solve this problem.

Yours Truly,
