WebApr 14, 2024 · This control acts by varying three flow rates: air supply flow; chilled water flow in the coil; and airflow in the cooling tower. ... In turn, the change in T chw affects the power consumption of the pumps, as it causes a variation in the chilled water flow rate because T chw changes the temperature difference in the plant loop, ... Webdirect-primary, constant flow pumping scheme. Here, chilled water is pumped at a constant flow rate which is independent of the cooling load. During part load conditions, which occurs most of the time, three-way control valves at cooling coils are used to bypass the chilled water back to the return line. Chilled water mixes with WebJul 15, 2014 · Your CHW supply is 10°C, your supply air is 19°C and you have an air supply-return air differential of 11°C. With the same air and CHW flow rates, it would stand to reason that if you provide CHW at 3°C (consider a 10-20% glycol mix) you could achieve a supply air temperature of 12°C and therefore a room (return air) temperature of 23°C. philosophical psychology pdf
