WebJul 15, 2016 · As a general practice I?d advise referencing the net peak listed for the baseline CHW loop in the PS-D report for determining plant peak cooling load, independent of chiller distribution. One difference between the numbers is that where SS-D is simply the peak load seen at the HVAC coils, the PS-D figure incorporates heat of CHW pumping ...

Web• Precooling of CHW loop – This configuration consists of a heat exchanger in the central plant that cools a chilled-water loop using water from a cooling tower. No additional cooling coils are required in the air handlers. This configuration exists in DOE-2.2, but operation is limited to hours when it can satisfy the entire WebJun 13, 2024 · The DES guidance for v4 refers you to Appendix G. Sections G3.1.1.1, G3.1.1.2, and G3.1.1.3 indicate it should be the CHW loop and the system 3 should be treated as an AHU. That said I think that you could consider the sub-cooling chiller to be a process load and therefore modeled identically in both models.
