HVAC: all the facts about the sector

The HVAC sector is experiencing a period of steady growth. 2021 was a revival year for the industry, during which actions were implemented to improve HVAC systems, including helping to improve air quality and reduce the risk of Covid-19 infection in indoor environments.

In this summary of the HVAC sector, we will explore the following topics:

What trends are shaping the HVAC sector? Click on the link below and download the free infographic to discover the development drivers of new heating and air conditioning systems.



The HVAC sector

The Heating, Ventilation and Air Conditioning sector is a complex industry that includes heating, ventilation and air conditioning systems, installations and technologies. It includes all the equipment and systems designed to regulate and control the thermal comfort of the domestic and industrial environment.
HVAC also refers to the treatment and management of a building's air quality so that it is healthy and safe for its inhabitants.


HVAC systems

HVAC systems are highly complex systems, designed through the skilful use of hardware and software components, designed to work together to manage the optimal comfort of an environment. With the advent of the IoT, the HVAC sector has also benefited from a technological acceleration that has put the entire industry on the cutting edge. Technological innovations applied to HVAC systems and devices are aimed at reducing residential and business consumption by focusing on high efficiency and a new distinctive design.

Areas of application

HVAC application areas include heating, air conditioning, ventilation and air purification. HVAC+R also refers to cooling and refrigeration systems: a globally important and growing industry, especially in China, Russia and the USA.

One of the most eagerly awaited conventions for professionals in the HVAC+R sector is MCE- Mostra Convegno ExpoComport, now in its 42nd edition. The international event, dedicated to companies in the renewable energy, energy efficiency and air conditioning sectors, will take place from 28 June to 1 July 2022 at Fiera Milano. An opportunity for in-depth analysis and exchange of expertise with those who design, build and install systems and equipment for the comfort of commercial, industrial and residential buildings.


What are the innovative aspects to focus on for the development of the HVAC sector? Find out in the in-depth study dedicated to Developments in the HVAC sector: hi-tech systems for sustainable comfort, two experts in the sector give their point of view on the drivers of the moment.


Air purification with UV Light

In recent years we have witnessed an exponential growth in the number of devices for sanitising and purifying air. In the wake of the Covid-19 pandemic, purifying the air we breathe in our homes has become almost a necessity. Here again, light plays a key role: HVAC systems integrated with UV light are designed to eliminate bacteria, spores, fungi and mould through the short wavelength, from 200 nm to 280 nm. Ultraviolet radiation acts on the DNA of these microorganisms, inhibiting their proliferation.


HVAC and sustainability: the latest trend

Today, it seems more urgent than ever that the improvement of domestic climate comfort is environmentally friendly. Some obsolete HVAC systems and devices are the main cause of excessive energy consumption. In fact, the use of energy for heating, ventilation and air conditioning systems is a significant point in the global energy balance. According to the “Energy Efficiency 2021” report, published by the International Energy Agency (IEA), these appliances play a crucial role in achieving zero emissions in the energy sector by 2050. Consumers are therefore called upon to choose technologies that have as little impact on the environment as possible. With this in mind, manufacturers must be able to guarantee a sustainable proposal of efficient solutions. One of the challenges of the coming years will be to balance sustainability and HVAC performance. The development guidelines foresee the use of renewable sources on the one hand and the support of smart technologies on the other.

Sustainability and energy saving were some of the topics we discussed with two HVAC experts. Read more about "Developments in the HVAC sector: a conversation with Franco Brambilla" and "Developments in the HVAC industry: a conversation with Bertrand Buttin".


SLIM solutions for the HVAC sector

SLIM's wide range of products includes standard and customised light signalling components for HVAC devices and applications. Solutions for the HVAC sector include: the TB/SLTS indicator light, also available with IP65 waterproofing, to be installed on water heaters and boilers for temperature signalling. Or, the TB/010/SC indicator light which, like all our products, has been awarded the main marks of conformity by European and North American certification bodies. Our technical department is always available to collaborate on the development of customised lighting solutions, whether they are functional components (temperature signalling) or aesthetic elements (light profiles and panel backlighting). If it is true that new devices are nowadays designed with the search for harmony between functionality, comfort and design in mind, then the lighting component of thermostats, water heaters and boilers must also be rethought to suit these new aesthetic trends.
