District Cooling System Design with
34°F Supply Water Saves on First Cost and Operating Cost!
Large chilled water systems such as those used in modern
District Cooling Plants are now being designed and operated
using 34°F (1°C) chilled water in their distribution
systems. this colder supply water temperature beneficially
results in systems that are much lower in both first cost
and in operating cost compared to systems based on 44°F
supply water. Lower energy consumption also results in a system
that is environmentally friendly. The comparisons below will
demonstrate how these benefits are achieved.
This information presents a comparison of a traditional
44°F (7°C) chilled water system versus a system
designed around 34°F (1°C) chilled water supply.
Both systems have a design return temperature of 54°F
(12°C). the data used in this report is taken directly
from several large operating district cooling systems. this
report also provides sufficient information to allow users
to make their own comparison using local conditions.
