Clean air is a basicrequirement of life. Thequality of air inside homesand commercial buildingswhere people spend a largepart of their life is an essentialdeterminant of healthy lifeand people’s well-being.Daikin offers a variety of solutions from small energy recoveryventilation to large air handling units for the provisionof fresh air ventilation to residential and commercial buildings.Ventilation solutionsControl of fresh air temperatureDaikin offers state-of-the-art ventilation solutions that caneasily be integrated into any project:›› Wide ventilation portfolio, unique among ACmanufacturers›› High-quality solutions complying with the highestlegislative standards›› Seamless integration of all products to provide the bestindoor environment quality›› All Daikin products connected to a single front endcontroller for complete control of the HVAC system.Daikin offers a range of inverter condensing units and chillers which canbe used in combination with Daikin Air Handling Units (AHUs) for theultimate in control over fresh air.There are four control possibilities when combining AHUs and Daikinoutdoor units, offering all the required flexibility for any installation.Multiple indoor units can be combined with the same outdoor unitto reduce the installation costs. For false-ceiling installations wherespace is a constraint, the VKM can fit perfectly, delivering fresh air at acomfortable temperature and with optional humidification.Energy Recovery VentilationOur energy recovery units recover sensible energy (ModularL Pro / Modular L Smart) or total (sensible latent) energy(VAM/VKM), substantially reducing the load on the airconditioning system up to 40%.Five components of indoor air quality:›› Ventilation: ensures the provision of fresh air›› Energy recovery: saves energy by transferring heat and moisturebetween airflows›› Air processing: delivers the right supply temperature to decrease theindoor unit load›› Humidification: ensures relative indoor humidity levels are respected›› Filtration: separates pollen, dust and pollution harmful to ficationFiltration 3

Five reasons why Daikin’sventilation range isunique in the market1Market leading controls& connectivity›› Interlocking ventilation and air conditioning system: Control ERV/HRV and air conditioning from the same controller Aligns the operation mode between the systems to save energy›› Easy integration in the total solution: Online control and monitoring via the Daikin Cloud Service Full portfolio integration in the intelligent Touch Manager,Daikin's cost-effective mini BMS›› User-friendly controller with premium design: Intuitive touch button control2Unique installation benefits›› Integrates seamlessly within the Daikin total solution,ensuring a single point of contact›› Total fresh air solution with Daikin supplying both theVAM/Modular L Smart and the electrical heater›› Daikin AHU and condensing unit connect Plug & Play thanks to samepipe diameters, factory mounted controls, expansion valves, etc.421 C
