GOLD version E/F, Function Guide,
SMART Link/AQUA Link
1. General
The
SMART Link
function is intended for use in controlling
the times, temperatures, etc. as well as reading the alarms
and settings of a Swegon chiller/heat pump via a hand-
held micro terminal and web page in a GOLD air handling
unit.
For electrical wiring and functionality at connection with
Nestor, see separate documentation.
1.1 Energy-saving functions
1.1.1 Control of the supply air temperature/supply
flow temperature
By comparing the supply air temperature downstream of
the fan with the supply flow temperature to the coil, the
equipment makes sure that the valve for the coil opens
only if the water has a temperature that conveys energy to
the air.
This means that if there is a heat load and the water tem-
perature is lower than the supply air temperature, which
can occur during defrosting cycles, the valve is not allowed
to open. If there is a cooling load, the reverse applies.
1.1.2 Optimisation function
A cooling unit/heat pump will be more effective if the dif-
ference between the outdoor temperature and the water
temperature is as small as possible. This reduces energy
consumption.
The supply air energy to a water coil is controlled by a
valve. Optimisation of the valve position so that it always
strives to be fully open, and instead control the water
temperature, saves energy.
1.1.3 AQUA Link
The AQUA Link provides both air handling units and
comfort modules with cooling power. Even here energy
savings are obtainable by allowing the need to control the
water temperature.
Depending on whatever the specific need is (dehumidifi-
cation, cooling of the supply air, cooling of the room via
comfort modules), the temperature of the chilled water
can be varied and the control system ensures that the
chiller will not produce chilled water that is colder than
necessary.
1.1 Installation
The installation work is fast and simple compared with
that of other systems. It requires only hydraulic and elec-
tric connection between the GOLD unit, chiller/heat pump
and possible AQUA Link.
All the necessary control functions are ready to activate.
One supplier of all the equipment.
