“Fresh, clean, warm air… and saving energy too!” – Duplexvent – The Airflow Solution for creating a healthier environment
Due to the ever increasing energy costs, the need to conserve heat and power is leading to higher levels of insulation and air tightness in the residential dwellings and the commercial buildings. The resulting poor indoor climate can many times lead to health problems for both the occupants and the visitors, and there can be long term damaging effects to the fabric of a building. The lack of effective ventilation within a well sealed environment increases the prevalence of airborne contaminants, odours and smells, which – together with high levels of humidity and condensation – add to the creating of an unhealthy environment. If left unchecked, the development of dampness leads to mould growth and the spread of mites which can increase the likelihood of headaches, allergies and the development of asthma in children.

What is the solution to the increasing indoor air pollution problem? Fresh, filtered air is the answer!
In a healthy home thousands of litres of fresh air is needed every day in order to compensate for the moisture generated by each individual person(the moisture is also generated through cooking, washing and bathing). Duplexvent provides continuous mechanical ventilation with heat recovery in order to supply controlled, fresh, filtered air while at the same time extracting potentially harmful, unwanted moisture and airborne pollutants. This system helps you to save the energy too by re-claiming waste heat from the extracted air that would otherwise be lost and returning it via the incoming fresh air into the dwelling. By adding back the warmed/fresh air the thermostat can be turned down (which event, over time, results in tangible benefits in reducing the energy consumption).
The Duplexvent System from Airflow – Effective and Efficient
Heat recovery is a process consisting of continuously preheating incoming cool supply air by warming it with the outgoing exhaust air. The warm air is not simply exhausted but it transfers most of its heat to supply air in a highly efficient heat recovery exchanger. At no time do the airstreams mix as the heat radiates through the plates of the exchanger.
What is Heat Recovery Efficiency?
The Heat Recovery Efficiency is the utilising of waste heat to cool fresh incoming air. Generally speaking efficiency above 60% is considered good (the efficiency above 80% is excellent). The heat recovery efficiency for the Airflow Duplexvent units is up to 90% (depending on the unit size, air flow and the heat recovery exchanger type).
The heat recovery exchanger is fitted directly in the ventilation unit. This allows use of heat recovery in all kinds of buildings/venues: flats, apartments, family houses and residential accommodation. Larger units can be installed in commercial buildings, swimming pools, retail and industrial buildings.
The Duplexvent units from Airflow also incorporate a “By-Pass” mechanism so that during the summer the supply air is not warmed unnecessarily. Heat recovery exchangers can be used even in air-conditioned buildings where during the summer season it serves as (cold recovery). The incoming warm air is cooled by air-conditioned exhaust air. This is a whole house ventilation system with heat recovery, as shown in the picture above(similar to the Whole House Ventilation System WHV8 series).
Fresh Air for a Healthy Environment
- For the maintenance of the building fabric and for a healthy indoor climate, controlled mechanical ventilation becomes essential.
- Energy savings can be achieved by improved insulating measures and by the use of heat recovery systems.
- Also, the carbon emissions in the dwelling are reduced with the contribution of heat recovery.
It is indeed very important that we have a healthy and comfortable climate, especially if we live in a highly insulated building. Research proves that people living, working or studying in inadequately ventilated buildings suffer from more ailments such as headache and allergies. Also, on average, humans spend 90% of their lives in closed buildings. Therefore, it is of prime importance to provide healthier indoor air, free from odours, high humidity and airborne pollutants.
How does the Airflow Duplexvent work?
The stale air is an air that is contaminated with humidity, toxins and smells extracted from the kitchen, bathroom and toilet. Outlet grilles in toilets and wet room areas, such as the bathroom, en-suite, utility and kitchen allow a constant or demand oriented air flow volume to be extracted, matched to the users’ individual needs or room demands. Much of the heat of the extracted air is retained by the exchanger and transferred to the incoming fresh external air.
The fresh air is fed directly from outside into the ventilation system through a filter. The heat taken from the extracted air is used to warm the fresh filtered air in the exchanger and then flows through ducting to termination points such as air valves or air inlets into the living rooms and bedrooms. By undercutting doors and fitting transfer grilles fresh air circulation is ensured throughout the dwelling.
