WebJun 21, 2024 · The typical brute-force method would require a dedicated glycol chiller to produce extra-cold CHW to reduce the dew point and then reheat it with HW. Instead, the team elected to use a desiccant wheel in series with a CHW coil on the primary 42°F CHW loop. This allowed for the elimination of the dedicated glycol chiller and reduced the … 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.
