Recent research shows that people nowadays spend almost 90% of their time in closed spaces. In this situation, the HVAC&R system must be able to guarantee comfort, energy efficiency and the health of the occupants.
Comfort, in other words maintaining the right internal hygrothermometric conditions for human occupancy, for a long time was the only parameter for assessing the suitability of a system.
Over the years, thanks also to the evolution in regulations, energy efficiency has taken on a significant role in guaranteeing the sustainability of the building-system as a whole.
The future challenge for tertiary systems will instead focus on the issue of people's health: guaranteeing air with a high degree of purity (free from dust, substances, microorganisms) and therefore high standards of IAQ (Indoor Air Quality) of the environments.
The “service sector” application covers a multitude of situations such as hotels, offices, shops, banks, restaurants and cafés, shopping centres and multi-purpose structures. The mechanical systems – and therefore the air conditioning units – have to adapt to the specific needs.
It becomes essential for operators in the sector to havewide choice of solutions: FAST, with over 30 years of experience, is the partner for every need capable of supplying from air treatment units to rooftops, from heat recuperators to units ducted.
In the context of systems for the service sector takes the form of units with the following main expedients for the specific application:
Fastaer air treatment systems improve comfort and increase energy savings by keeping the air always healthy, oxygen-rich filtered from the outside and dehumidified.
Air handling units can be installed in homes, apartment blocks, commercial and industrial premises. They improve air quality, hygiene and comfort.
To achieve Class A, it is essential to reduce ventilation losses by means of a controlled mechanical system with high-efficiency heat recovery.
The units combined with the distribution system ensure high efficiency in the entire ventilation process:
