What is it?
This
modification revises control setpoints
for AC condenser water control valves and investigates
transient
conditions,
such
as starts and cooling load fluctuations.
How
does
it work?
The specific power (kw per cooling ton)
of the 200-ton HFC-134a AC plant is much higher than expected and unnecessary
fuel and energy is being consumed. An
increased setpoint will
allow the ship to use less energy to function as the temperature gets closer to
the optimal ship design temperature at which the ship was intended to operate.
What will it accomplish?
Revising
setpoints
will use less energy and investigating transient conditions will ensure
shutdowns are not experienced with new setpoints.
