Aerel's Climatop evaporative injection air conditioning

The evaporative injection air conditioning technology developed by Aerel is a French innovation, patented throughout Europe and soon in the United States.
According to Aerel, this type of air conditioning could save, in France alone, 234.000 tonnes of CO2 and 50 million litres of diesel per year, and preserve lives ...

Aerel's evaporative injection air conditioning is beginning to attract the interest of local authorities and the agricultural sector, which are receptive to its benefits in terms of a favourable impact on the greenhouse effect, cost savings, and improved occupational health conditions.

An advance for sustainable development, measured and validated by ADEME

Many years of research and development have produced a seemingly simple but ultra-high-performance system which, according to the firm Aerel, promises to be a revolution in air conditioning for machines in the agricultural, public works, road maintenance and public transport sectors.

Available in three families of air conditioners (Climatop, Climapur and Climacool), evaporative injection air conditioning uses no refrigerant and no compressor.

The air is treated through a reactor-nebuliser in which water is injected according to defined parameters. Three performances are achieved simultaneously: lowering of the temperature, rehydration, and purification.

An electrical connection to the machine's battery would be enough to power the system.

It can be integrated as original equipment by manufacturers, or is available as modular kits designed to easily equip machines already in service. This innovation is said to be more efficient than all the technologies already known (conventional refrigerant gas air conditioning, evaporative air conditioning, humidifiers), not only in terms of air conditioning, but also of air purification and environmental gains.

Supported by ANVAR and validated by an ADEME study, the technology developed by Aerel meets the three requirements identified for sustainable development:

- Economic progress: it operates without a compressor. Aerel's evaporative injection air conditioning would thus use ten times less power than gas air conditioning (0,5 ch instead of 5 ch).

Given that an air-conditioned diesel vehicle consumes 20 to 35% more, i.e. on average over the year 5% more fuel than those that are not air-conditioned ... the potential saving could amount to 50 million litres of diesel per year (42.000 toe/year) in France.

- Social progress: air purification would be real progress in terms of occupational health and comfort.

Whereas gas air conditioning relied on keeping the cab airtight (hypothetical in practice) and on mostly recirculating confined interior air, Climatop works on the contrary with 100% fresh air and constantly injects into the cab air that is 100% controlled, cooled and purified, thus fully pressurising the cabin and making cabs that are not or no longer airtight aeraulically sealed.

Users already note the pleasant feeling of healthier, more natural air, and fewer headaches and less dry throat.

- Environmental progress: compared with gas air conditioning, Climatop would significantly reduce greenhouse gas emissions (CO² and NO²), since these are caused by excess fuel consumption and by refrigerant releases (the latest generations of these fluids remaining 1000 to 3000 times more harmful than CO2 itself).

The stake: a potential saving of 234.000 tonnes of CO² per year thanks to evaporative injection air conditioning.

Finally, one last argument that makes it a truly sustainable solution ... Climatop is fully reusable: whereas gas air conditioning is lost each time a machine is replaced, it would take less than an hour to recover and transfer the Climatop.
