HVAC system inefficiencies and poor occupant comfort
Facility managers continue to focus on improving energy
efficiency to reduce costs. Yet an often-overlooked area is
hydronic heating and cooling systems. Many of these
systems do not respond quickly or accurately to load,
pressure and flow changes. Because hydronic systems are
dynamic, water pressures change continuously in the system
as valves open and close, pumps start, stop, and change
speed, and pump impellers wear. With any change in
pressure, there is a corresponding change in flow through
the control loop, even if the heating or cooling load is
constant. The results are wasted energy and difficulty
maintaining consistent temperature and occupant comfort.
Improve efficiency and comfort through better
hydronic control in HVAC applications
Unlike conventional control valves, Siemens PICVs respond to
unavoidable system pressure fluctuations because the PICV’s
automatic differential pressure regulator constantly adjusts
to pressure changes. The constant flow through the PICV,
regardless of pressure fluctuations in the system, increases
heat transfer through the coils. The result is maximized ∆T
which significantly improves energy usage and cost savings
by preventing an over-supply or under-supply of heating or
cooling energy. Also, more accurate temperature control also
enhances occupant comfort.
Siemens PICV have the unique advantage of always
maintaining their full stroke, regardless of the maximum
adjustable flow setting, to provide better control. Pair them
with SQV spring return actuators and SAX or SAV non-spring
return actuators with all control signal and failure mode
combinations for a wide range of applications.
