We are paying more and more attention to the energy efficiency of our buildings, but there is an equally important aspect that often goes unnoticed: the quality of the air we breathe.
Increasingly airtight homes, busy offices, commercial spaces, and schools require constant ventilation to eliminate stale air, excess humidity, and indoor pollutants. However, opening windows means losing some of the heat or air conditioning that is so hard to generate.
This is where heat recovery units make all the difference. These systems allow for continuous air renewal while recovering a large portion of the thermal energy from the expelled air, achieving significant energy savings without compromising comfort.
What is a heat recovery unit?
A heat recovery unit is a mechanical ventilation system that extracts stale air from inside a building and introduces clean air from outside.
The key lies in its heat exchanger: both airflows cross paths inside without mixing, transferring the temperature from the outgoing air to the incoming air. This way, in winter the outside air is preheated, and in summer, the fresh air helps maintain the indoor climate control.
The result is a much healthier environment and lower energy consumption throughout the year.
Energy savings without sacrificing comfort
Ventilation is essential to maintain good air quality, but it can also become a major source of energy loss.
Aspirnova's heat recovery units incorporate high-efficiency exchangers capable of recovering more than 73% of the thermal energy from the extracted air, considerably reducing the building's heating and cooling demand.
This translates to:
- Lower heating consumption.
- Reduction in the use of air conditioning.
- Reduction in energy bill.
- Greater overall building efficiency.
- Smaller carbon footprint.
Improved indoor air quality
Indoor air quality has a direct impact on our well-being and our health.
Insufficient ventilation promotes the accumulation of CO₂, humidity, odors, dust, allergens and other contaminants that can affect people's comfort and performance.
Aspirnova heat recovery systems incorporate high-efficiency filtration systems compatible with RITE regulations and allow the addition of CO₂ or humidity probes to automatically adapt the operation of the equipment according to the actual needs of the building.
Thanks to this, it is possible to maintain clean and renewed air throughout the day without needing to open windows.
Aspirnova technology: efficiency and reliability
Aspirnova heat recovery units stand out for combining high energy efficiency with a robust construction and multiple control options.
Its main features include:
- Low energy consumption EC Inverter motors.
- High efficiency heat exchangers.
- Motorized bypass for free-cooling and free-heating.
- High-quality double filtration.
- Control via LCD screen.
- Compatibility with BMS systems via Modbus protocol.
- Possibility of control using CO₂ or humidity probes.
- Easy installation thanks to the system plug & play.
All of this allows the system's operation to be adapted to each installation, optimizing energy consumption and ensuring efficient operation throughout the year.
Horizontal or vertical heat recovery unit: which one to choose?
The range marketed by Arelia offers solutions for different types of installations.
