10 Introduction to Ventilation
Defining Munters’ TRIO ventilation consists of three elements:
•
Defining the Minimum and Maximum Ventilation: Defining the minimum and maximum
ventilation defines how much air is required for any given growth day. Based on these
requirements, TRIO determines which fans run.
•
Defining the Fans/Ventilation Scheme: Defining the fans/ventilation determines how much air
the fans provide and which fans provide the air.
•
In addition, TRIO controls the inlets and tunnel doors.. There are two ways to control the inlets
and tunnel doors:
o
Static pressure: Based on the difference in the interior and exterior air pressures, TRIO
continually calculates the inlets’/doors’ opening positions. When inlets/doors change to
another level, they do so before the fans increase/decrease to that level. Note that TRIO
uses the positions assigned to the inlets/tunnel doors levels as the minimum position.
o
Position control: The user can define the opening positions of the inlets, outlets, and tunnel
doors by level. Note that when inlets/doors change to another level, they do so before
the fans increase/decrease to that level.
•
Inlet control is fully explained in Inlet and Curtain Ventilation, page 123.
10.1 Defining the Minimum and Maximum Ventilation
In setting up the Climate > Min/Max Ventilation screen, the user defines the lower and upper ventilation
limits during the growth cycle: the minimum and maximum amount of air exchange allowed for each
growth day.
•
When minimum ventilation is operating, the ventilation works to ensure that there is sufficient
clean air while keeping the air temperature close to the target temperature.
•
The maximum limit ensures that the birds/animals do not receive too much air during any
particular growth stage.
•
If the temperature is above the target temperature by a sufficient amount, the ventilation level
increases. If the increase in ventilation does not reduce the temperature, ventilation increases
until it reaches the maximum amount defined for that growth day.
•
If the temperature decreases to a user-defined point, heaters can turn on. At this temperature,
ventilation will be at the minimum level.
Options:
•
Day curve only.
•
Dynamic Ventilation: This option enables increasing or decreasing the minimum/maximum
ventilation based on the outside temperature.
o
Dynamic minimum: The controller adjusts the minimum between the cold and warm set
points according to the warm and cold outside temperature set points.
o
Dynamic maximum: The controller adjusts the maximum between the maximum cold and
max warm set points according to the warm and cold outside temperature set points.
