Léviathan Dynamics, a small revolution in the field of air conditioning without fluorinated gases

Summer should soon arrive and the question of air conditioning will arise again! Are we going to equip ourselves? Is this useful? Economic ? Ecological? A solution has been emerging for several years, through the start-up Léviathan Dynamics, based in La Courneuve (93). Indeed, it offers innovative air conditioning, called TURBEVAP LD40, based on water for refrigerant liquid, eliminating, therefore, fluorinated gases usually used. I remind you that a fluorinated gas is a chemical compound used as a refrigerant fluid in cooling systems, this is the case, for example, of hydrofluorocarbons (HFCs), the most common. Léviathan Dynamics is reinventing air conditioning with water as its source. Decryption.

Why replace fluorinated gases?

Hydrofluorocarbons (HFCs) are very efficient at transferring heat, making them ideal for refrigeration and air conditioning systems. In addition, they are not flammable, thus protecting the systems from a possible fire. On the other hand, they are harmful to the environment, because they have a high Global Warming Potential (GWP). This means that they are more powerful than CO2, for example, and therefore contribute greatly to global warming. By replacing these gases with water, Léviathan Dynamics offers a sustainable solution to reduce greenhouse gas emissions, particularly in a context in which the demand for air conditioners is increasing rapidly. With global warming now a fact and no longer a hypothesis, the air conditioning market is booming.

Water air conditioning

The operating principle of Leviathan Dynamics air conditioning is based on the use of water as a refrigerant. The water evaporates, absorbing heat from the surrounding air and causing what is called biomimicry. In fact, the innovative air conditioning of the Ile-de-France start-up works according to a process similar to human sweating. To do this, the two co-founders and engineers Karino Kang and Alan Chauvin, designed a compressor capable of compressing water vapor. This small technological feat makes it possible to maintain a size compatible with current uses while eliminating greenhouse gas emissions.

Mechanical vapor compression

Now available, the company’s water air conditioning works thanks to mechanical vapor compression, and is also suitable for hard, even very hard, therefore limestone, water. Another strong point is that it recovers pure water from wastewater, thus creating a new system of recycling and reuse of wastewater. In most companies, this issue of wastewater recycling is a major problem. Refreshing offices by recycling this water is an excellent idea! As you will have understood, this innovative air conditioning is aimed more at industrial or commercial buildings, and not at individuals, for the moment. The company specifies the following data regarding its technical characteristics:

• Consumes 40% less energy than a traditional evaporator
• Low maintenance costs
• Treatment capacity per hour: 40 l
• Treatment capacity per year: 320 m³
• Electrical connection: 3 kVA – 230 V mono
• Energy consumption: 45 kWh/m 3
• Weight: 250 kg
