Revision history [back]

I made a system with low temperature radiant ceiling and Heat exchanger desiccant system. Heat exchanger desiccant operated with a DX cooling coil for dehumidify and cooling， this is the HVAC air system served as a secondary cooling device at summer and radiant system is the plant loop which served as a primary cooling device at summer. Thermostats were set as 26 degree at summer. The cooling control temperature schedules were also set as 26 degree at summer. Air Terminal :Single duct :uncontrolled worked as HVAC air system's terminal. Desiccant + DX cooling coil + terminal machine are operated with low temperature radiant system while Air Terminal :Single duct :uncontrolled is combined with radiant system in the Zone HVAC :Equipment list. I compared with example files when established this system. I guess my system is same as the example file, so I cannot understand why my radiant system don't have the cooling rate. I've been struggling with this problem for one month, so I need your help. I have no other ideas to solve this problem. Thanks for your attention and looking forward your help. Welcome everybody to comment. The attachment is the IDF file of my case. Please refer to this.
