Zehnder ComfoFreshAir Distribution Network

Continuous, efficient comfort for the health of both you and your home.

Zehnder Comfosystems offer a collection of indoor climate solutions which are suitable for every home. They are designed to provide efficient and economical comfort, supply heating, cooling, ventilation and hot water, delivering comfort on every level whilst helping to reduce energy consumption for the homeowner.

Previously, the ducting for these ventilation systems has been a commodity product which has provided a low-tech conduit to transfer air. Zehnder Comfosystems have reinvented the concept of ducting with their ComfoFresh air distribution network and used their expertise to improve airflow, efficiency, air quality and hygiene as well as designing aesthetically pleasing grilles and terminations.

• A ground loop containing a brine solution is installed below the ground’s surface (method as shown in the diagram). The brine in the ground loop is pre-heated or pre-cooled by the temperature of the earth (Zehnder ComfoFond L option).

For more information on ground source heat exchangers, please see the Zehnder Comfosystems ComfoFond brochure.

3 The Zehnder ComfoAir heat recovery ventilation system works to extract air from wet rooms (kitchens and bathrooms) running around the clock. It takes energy which would otherwise have been lost during the extract process and transfers this to the fresh, filtered supply air which is being drawn in from outside.

In some instances, the environment within an air tight home can become too dry for comfort. It is possible to upgrade the heat exchanger on selected units to the Zehnder Enthalpy Heat Exchanger. Not only does this product extract heat from extracted

air it also extracts water vapour which can then be used to regulate the humidity of supply air to ensure it is optimised for comfort with no loss in performance.

4 The Zehnder ComfoAir system is connected to the Zehnder ComfoFresh air distribution system which delivers fresh, filtered air to habitable rooms. The air has been tempered by heat recovered from extracted air.

The ventilation rate – the amount of air which is either extracted or supplied – can easily be adjusted on a room by room basis to ensure that the system performs at its optimum.

Zehnder Comfosystems can offer a wide portfolio of complimentary products which are designed to be effortlessly integrated into one functioning and effective system. Whether you choose a Zehnder ComfoAir heat recovery ventilation system or a Zehnder ComfoBox unit providing heating, cooling, ventilation and hot water, all of our units are designed to provide the benefits of energy efficiency, health and comfort. In order to maximise these benefits the units should be used with Zehnder ComfoFresh components.

1 2 Air is drawn into the Zehnder ComfoFresh ducting network in one of three ways;

• Fresh air is drawn in from outside via a wall vent

• Fresh air is drawn in from outside via an air intake tower and linked to the home using a ground loop. The air is pre-heated or pre-cooled by the temperature of the earth (Zehnder ComfoFond option).

Zehnder ComfoFresh Benefits

HealthFresh air is essential for both our health and our sense of well being. On average, we spend 70% of our time inside therefore the systems and accessories which ventilate these spaces can impact on us significantly. Advances in construction materials and methods have made these indoor spaces increasingly energy efficient and air tight but this may mean that inhabitants of these spaces are potentially paying the penalty with health related issues. Poor ventilation and air quality can lead to an increased incidence of asthma and allergic symptoms due to sensitivity to allergens such as dust mites, VOCs, pollen and mould. By improving ventilation, the concentration of these allergens can be reduced.

ComfortThe Zehnder ComfoFresh air distribution network is designed to deliver a measured amount of air at low velocity, ensuring that fresh, clean air does not create drafts around the home. Due to the unique design of the components, noise related to air turbulence can be reduced thus limiting the intrusion of noise into the home environment. Visible components of the system (valves and grilles) have been aesthetically designed in high quality materials so as they are in harmony with your indoor environment.

Energy EfficiencyPressure losses are reduced owing to the smooth inner surface of the ducting. Improving the efficiency of your ducting means that your central system may not need to work as hard to achieve the desired airflow, both prolonging its life and helping to improve the energy efficiency of your system.

Zehnder ComfoFresh Benefits

6Zehnder ComfoFresh Features

Zehnder ComfoFresh Features

Improved HygieneConventional ducting can contain ridges and furrows which allow dust, dirt and moisture to become trapped. These health hazards and potential allergens can transfer themselves to the filtered fresh air being supplied to the habitable rooms of the house thus degrading the air quality and affecting the health of the inhabitants. Zehnder ComfoFresh ducting and accessories have a smooth interior surface which prevent these potential contaminants from being collected and make the inner surface of the duct easy to clean with our specially designed tool (pictured above). In addition to this, the Zehnder ComfoFresh OnFloor components are manufactured from food grade plastic.

Improved PerformanceZehnder ComfoFresh products are designed in a unique way. The concept of ducting design has been revolutionised and the resulting components can significantly improve the performance of the associated ventilation system. Unlike conventional systems, Zehnder ComfoFresh systems feature a manifold fitted directly after the ventilation device. The manifold has a dedicated duct run to each room requiring extract or supply ventilation. This differs from the more standard long duct run with branches off to each room and can offer benefit as air is being distributed more evenly in many directions simultaneously from a central hub therefore improving efficiency. By utilising Zehnder ComfoFresh products in the suggested configuration, both the installer and the end user can be confident that they are achieving the specified performance of the scheme. This has long term benefits for the health and well being of the homeowner as well as ensuring that the integrity of the building fabric is not degraded.

Improved Installation TimeAvailable in 20 and 50 metre rolls, the semi-rigid ducting can easily be used for longer duct runs and can easily be curved over and under obstacles such as joists and pipes. This ability to deviate from a straight run coupled to the fact that installers do not need to make lots of joints, means that significant amounts of time and money can be saved.

Zehnder ComfoFresh OnFloor System

This system is designed to be installed either in the insulating layer on top of a concrete floor or in the traditional way, in a ceiling void. The semi rigid ducting is designed to be bent both vertically and horizontally and is available in 20 and 50 metre lengths to give the installer the most flexibility and the least number of connections when fitting. Connections between components are a push fit using sealing rings to facilitate a quick and airtight joint. Airflow adjustments for each individual duct are made at the central manifold rather than at a supply or extract valve. This allows Zehnder Comfosystems to couple their Zehnder ComfoFresh ducting with aesthetically pleasing, low profile grilles which are more attuned to the decor of stylish, contemporary interiors.

Zehnder ComfoFresh InFloor System

This system is designed to be installed in the concrete layer of the floor. The semi rigid ducting is designed to be bent both vertically and horizontally and is available in 20 and 50 metre lengths to give the installer the most flexibility and the least number of connections when fitting. The flexibility of the tubing does not, however, compromise its strength and ability to resist deformation of shape owing to forces acting on it. Like the Infloor system, connections between the components are a push fit using sealing rings to facilitate a quick and airtight joint. Like wise, airflow adjustments for each individual duct are made at the central manifold rather than at a supply or extract valve, allowing the use of aesthetically pleasing, low profile grilles for stylish interiors.
