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 … WebMay 21, 2024 · Then, we have the Secondary loop or the DISTRIBUTION LOOP.
