The new function optimises the water temperature based on the actual need in the room, as well as it connects the WISE-system with the cooling/heating production unit. This function reduces the energy use for cooling and heating with up to 15%. It also contributes to a greater comfort, reduced risk of condensation and makes it easier to avoid oversizing of production units.
Water optimisation is a function that is a part of Swegon's WISE-system which takes full control of a building's HVAC-system. The function optimises the inlet water temperature depending on the actual need at room level. The function ensures that the temperature difference is as small as possible between demanded and supplied inlet water temperature which will minimizes the energy required to heat or cool. It reduces the energy use for cooling and heating with up to 15%. For example, 3% energy can be saved for every degree the cooling water temperature is raised and 2,5% energy can be saved for every degree the heating water temperature is lowered.
The function also comes with other benefits, for example:
• By optimising the inlet water temperature and increasing the inlet water temperature during cooling the comfort increases since the risk of draught is lowered. At the same time the risk of condensation is also lowered.
• Since the system normally can handle higher inlet water temperature during cooling, compared to a system without the optimisation function, free cooling can be used to a greater extent and thus save energy.
• It is also possible to avoid oversizing of production units. Simulations show that buildings only need full effect about 10 days a year - the rest of the year it could manage with less capacity.
