4 Why Indoor Air Quality? We spend 90% of our time indoors in closed spaces such as schools, buildings, offices, etc. But did you know that the indoor air can be up to 2-5 times worse than the air outside? Due to growing urbanization and high insulation of the buildings, pollutants get trapped inside leading to poor indoor air quality causing moisture increase and other health issues. Sources of indoor air pollution are more common than we think. VOCs released from cleaning products, furniture, or even from new building materials can linger inside. Pollution from the outside released from vehicles, etc. can also be a potential source of indoor air pollution. Poor IAQ is linked to respiratory short-term issues like allergies, asthma, and also in the long term to diseases such as respiratory infections, and cardiovascular disease. The risk is greatest for the elderly and young children who tend to spend more time indoors. Opening windows could also lead to ingress of pollutants and substantial energy losses. Moreover, many situations linked to security, acoustic, outside pollution, etc… do not allow to make use of them. The solution? A combination of various components such as ventilation, air processing, filtration & air purification can contribute to better indoor air quality. Watch our indoor air quality video on YouTube to learn more about sources and consequences of poor air quality.
5 Ensures the provision of fresh and clean outdoor air and removes contaminated stale air Delivers energy savings by transferring heat and moisture between airflows, thus helping to condition the supply air to the required indoor temperature and humidity levels Delivers the required conditioned air to optimise the energy efficiency of indoor HVAC equipment Ensures clean and healthy air by filtering out pollen, dust, odours and other contaminants that are harmful to our health Ensures the desired moisture level in the conditioned space Air processing Filtration & purification Energy & recovery Ventilation Humidification 5 components for ensuring good indoor air quality Ventilation Ventilation systems ensure optimal climate conditions by providing a fresh, healthy and comfortable environment for buildings of all sizes and applications. When a room is enclosed, air cannot easily enter or leave, allowing airborne pollutants to remain and accumulate within the space. This concentration could have an impact on the health of the room’s occupants. Ventilation is essential for diluting and removing these pollutants. A well-maintained ventilation system and adequate air-exchange rate have been demonstrated to be an effective solution to protect people from contaminants, including viruses.
6 Commercial ventilation
7 Daikin offers a variety of solutions from small energy recovery ventilation to large-scale Air Handling Units for the provision of fresh air ventilation for commercial premises. Unique portfolio within DX manufacturers that can easily be integrated into any project High-quality solutions complying with the highest Daikin quality standards Seamless integration of all products to provide the best indoor climate All Daikin products connected to a single controller for complete control of the HVAC system Energy Recovery Ventilation Our energy recovery units recover sensible energy (Compact L/ Compact T) or total (sensible + latent) energy (VAM/EKVDX/VKM-GBM), substantially reducing the load on the air conditioning system up to 40%. Ventilation with DX connection - Control over fresh air temperature Daikin offers a range of inverter condensing units to be used in combination with Daikin AHUs for ultimate control over the fresh air. There are 4 control possibilities when combining AHU and Daikin outdoor units hence offering all the required flexibility for any installation. Indoor units can be combined to the same outdoor unit to reduce the installation costs. For false-ceiling installations where space is a constraint, the VKM can fit perfectly to deliver fresh air at a comfortable temperature and it has an optional humidification element.
