Air temperature optimisation
SuperWISE continuously calculates and adapts the supply air temperature to the room’s heating and cooling requirement, limiting the need for additional heating/cooling.
Main functionality
The function of air temperature optimisation continuously adapts the supply air temperature between pre-defined setpoints. It then varies between 0-100 % cooling or heating. “Absolute” and “relative” are the two alternatives for controlling the supply air temperature.
Absolute uses the defined temperature limits when calculating the supply air temperature, while relative also accounts for the room temperature.
SuperWISE monitors underlying rooms’ heating or cooling need, 0-100%. The supply air temperature is calculated using the lowest, the highest, an average, or a weighted temperature need.
Added value
This optimisation function generates notable benefits, such as:
- Reduced energy consumption
- Increased free cooling possibilities
- Improved indoor environmental quality
- Increased flexibility, may be used in combination with pressure position optimisation
- Connected SuperWISE and GOLD, no BMS needed
Description
- Temperature setpoints for standard mode (0%) as well as 100% cooling and heating respectively are set in SuperWISE.
- SuperWISE monitors the cooling/heating demand in all rooms included in the duct system.
- Based on the selected method for analysing (min, max, average, weighted average), an overall heating or cooling demand is defined.
- The defined heating/cooling demand is used to calculate the supply air temperature setpoint (absolute method).
- The calculated setpoint for the supply air temperature is communicated from SuperWISE to the air handling unit.
Technical details
The rooms relevant for the calculation may be defined in SuperWISE.
Using the relative calculation method, a maximum difference between the supply air temperature and the room temperature can be determined.
When changing the maximum difference, the temperature change will either be lighter or more powerful than what the absolute method allows.
