39 On-demand ventilation Historically, CHRV-units were running continuously: 24 hours a day, 7 days a week. This was deemed to be “ok” as there was “heat recovery” anyway, and so the energy losses were deemed to be small. DUCO feels that this “old school”-way-of-thinking is a thing of the past and decided to go a step beyond the “normal” operation-mode of a “traditional” CHRV-system. So next to offering user control options on the display or via a remote control; next to offering the possibility to make the unit function on a time-schedule, DUCO also offers true “on demand” solutions which result in true energetically optimised ventilation-solutions: only ventilate when necessary, where it is necessary and for as long as it’s necessary. Sensors permanently measure the indoor air quality in a room (or centrally, depending on the need): if the indoor air quality (CO2 or humidity) is found to be OK, the ventilation is put to a strict minimum (minimum energy consumption and minimum heat losses). On the other hand, if the indoor air quality is found to be or become worry-some, the ventilation is triggered immediately in a modular way, i.e. more or less intense according to intelligent algorithms (energy is only used when needed to reach healthy indoor air). With an “on demand” DUCO-system, the occupant can always be assured to breathe the best possible indoor air, whilst also using the least amount of energy! DUCO brings you the smartest ventilation solutions! How does it work?
