Cooling Boost - Swegon GOLD RX Operation And Maintenance Instructions

6.4.2.12 Cooling Boost

Cooling Boost (forced cooling) means that the supply air and
extract air airflows are increased to convey more cool air to the
premises.
The fans are permitted to operate in the range between current
flow modes or pressure (low speed, high speed) and the preset
max speed. See Section 6.4.1.2.
The function can be selected in five variants as follows:
Comfort
The cooling outputs are activated if there is a cooling load.
A regulated ramp function switches in and gradually increases
the airflow when there is a cooling load, and the supply air
temperature is 3 K (preset at factory) higher than the preset max.
supply air temperature.
Economy
Cooling Boost Economy initially uses a higher airflow to cool the
premises, before a start signal is transmitted to chillers.
The function can also operate without the cooling function
activated.
In the event of a cooling load, the airflows are slowly increased
up to preset maximum flow. When the flows are up to max and
if a cooing load is still present, the output contacts for cooling
are activated.
The function requires that the outdoor air temperature is at least
2 K lower than the extract air temperature for it to be activated.
The normal cooling function is activated if the temperature dif-
ference is too small.
Sequence
The Cooling Boost Sequence is used if a chiller is sized for a
higher cooling flow than normal flow.
If there is a cooling load, the flow is increased up to the preset
max. flow and the cooling function is activated afterwards.
The Cooling Boost Sequence is blocked if no cooling function
has been selected.
Comfort and economy
The comfort variant and the economy variant can be combined.
The function that has the highest signal (highest setpoint)
applies.
Economy and sequence
The economy variant and the sequence variant can be com-
bined. The function that has the highest signal (highest set-
point) applies.
Sequence and comfort
The sequence variant and the comfort variant can be combined.
The function that has the highest signal (highest setpoint)
applies.
Comfort, economy and sequence
The comfort variant, economy variant and the squence vari-
ant can be combined. The function that has the highest signal
(highest setpoint) applies.
