Airzone HVAC control solutions for residential projects

In a world where convenience is prioritized above all else, consumers are very demanding, especially when it comes to improving the quality of their home life.

This means that where the design of residential projects is concerned, there are a number of major priorities to take into consideration with regards to air conditioning.

What are the needs of residential buildings?

HVAC solutions for residential projects are different to those for an office or a commercial space in one major way. In those, other factors have a much larger influence on the decision-making process - primarily initial costs and energy consumption.

When in the home, however, the comfort and the convenience of its occupants is the principal priority. At home, we want an HVAC system that we can control and which works for the benefit of everyone.

What’s more, in a residential building, aesthetics are much more important. We want the system to be as unintrusive as possible, in terms of visual and audible impact - both inside and out.

The most obvious solution to meet these criteria is a ducted zoning system.

Zoned systems have major advantages over traditional systems. With independent control over the temperature of different zones (or rooms), it is much easier for individual needs to be met.

Users want to be able to control the temperature of their zone without affecting the comfort of others in different zones - with Airzone Easyzone this is all possible.

Whether through the intuitive thermostats or the Airzone Cloud app, the control of every zone is literally in your hands. You don’t even have to get off the sofa.

Technical and control criteria

From technical and control points of view, the Airzone Easyzone zoning system provides significant added value to any HVAC installation in a residential building.

One way is by creating a substantial increase in acoustic comfort. With the centralization of the installation,  the indoor units can be moved to a part of the home that is infrequently used, away from areas such as the bedrooms and the living room. This minimizes noise disturbance overall and removes any possibility of being kept awake by whirring.

Airzone Easyzone’s ability to integrate with home and building automation systems is an added plus. This can be performed directly through the Modbus protocol or through the integration gateways for systems such as KNX or BACnet.

However, with energy prices soaring and environmental concerns increasingly at the forefront of our consciousness, reducing energy costs is now a major consideration for residential projects.

Potentially enormous savings

The savings that Airzone Easyzone systems can give not only to end users but also professionals is perhaps the biggest advantage we have over our competitors.

The Airzone residential solution allows you to reduce the number of indoor units installed. This therefore helps to reduce installation costs, with additional savings made with the number of lines, support brackets and mounting accessories needed for the project also subsequently reduced.

This is good news for installers with set-up time made shorter as a result. Additionally, with centralized points, maintenance actions are simplified and will be fewer in number.

Once installed and operational, power consumption is lower than traditional systems for a number of reasons. Firstly, the system operates on a low voltage, only powering-up the dampers when they are in operation (not spring-open or spring-close).

Secondly, as Easyzone systems operate according to user preference and not on a maximum power threshold, lower capacity A/C units can be installed, lowering costs, both during use and at the time of installation.

Most importantly, however, a large amount of control over energy efficiency is in the hands of the user. Thanks to Eco-Adapt technology, a mode that the user can employ if they choose to, you can see exactly how efficiently the system is operating. You can then select the desired degree of energy efficiency, giving total control over energy usage and potential savings.

Case study: an apartment in Lisbon

An in-depth case study on a home in Lisbon (Portugal) shows just how far an Airzone installation can reduce energy usage and help save money.^[1]

The apartment was divided into five areas (three bedrooms, living room and kitchen) and two different HVAC solutions were compared: multi-split type A/C units and the Airzone control solution with a ducted A/C unit and motorized plenum. In both cases the same brand for the A/C units were chosen for installation.

Overall, the Airzone HVAC solution’s installed refrigerating capacity was 31.6% lower, producing annual energy savings of 18% compared to the multi-split solution. However, savings reached as high as 50.6% with Eco Adapt employed in the A++ mode.

If we also take installation and maintenance times into account, they were reduced by 63% and 60%, respectively, in the case of the Airzone HVAC solution. Let’s not forget that these time savings, of course, will also be reflected in a lower cost of labor.

Incomparable advantages

As these figures show, Airzone solutions can bring numerous benefits to residential projects that alternative systems are unable to beat.

Users are given a superior level of comfort that they can control, while costs are reduced both before and after installation.

That’s not to mention the speed and ease at which installers and maintenance can get and keep Airzone systems functioning to their fullest potential.
