The only coolant is air!

Dynamic Air Cooling

The only coolant is air.

Team of experts in gas and thermodynamics has developed a fundamentally new technology for cold generation and successfully tested a cooling device based on this technology.

On the basis of general theoretical studies we developed an original mathematical model of the process of Dynamic Air Cooling (DAC). The mathematical model allowed to perform the calculations necessary for the development DAC technology and construction of a DAC generator. 

DAC generator directly converts warm air into cold air. Excess thermal energy of air in the DAC generator is transformed into mechanical energy.

Principal difference

between Dynamic Air Cooling technology
and traditional vapor compression

Vapor compression uses  cooling  agent to subtract part of the air´s thermal energy and transport it outside the Cooling system. VC system has more elements and is more complicated.

DAC generator directly converts warm air into cold air. Excess thermal energy of air in the DAC generator is transformed into mechanical/electrical energy.

DAC Working scheme

A dynamic cold generator consists of an electric centrifugal compressor (1) and a working element (2).

The working element is constructed on the basis of the developed mathematical model and is the subject of know-how. The centrifugal electric compressor (1) of the DAC Generator sucks in air and generates a flow of air that is directed to the input connection of the Working Element (2). Part of the internal (thermal) energy of the air is converted into mechanical energy inside the Working Element. The whole process results in effective and quick air cooling - 

DAC allows to achieve temperature delta of up to -60°C in very short period of time.

Most prominent advantages

of DAC technology

over traditional systems

0

No thermal contamination of the atmosphere


0

No coolants and refrigerants that have a greenhouse effect or contribute to the destruction of the Earth's ozone layer

No limits

DAC is not affected by environmental regulations (emission limits)

-60°C

DAC allows to achieve temperature delta of up to -60°C in very short period of time  

30%

Lower CAPEX comparing to traditional A/C systems

50%

Lower OPEX comparing to traditional A/C systems

Ready-to-use

Ready-to- use straight from the box  - does not require installation

No bugs

Does not create favorable environment for the emergence and reproduction of pathogenic fungi, pathogens and bacteria

Compatibility

DAC technology can be used to quickly and cost-effectively upgrade existing cooling and A/C systems

Degree of project readiness

Theoretical and research works completed.

Preliminary experimental-design works were done.

Prototype of the working element was made and tested.

Experimental prototype is constructed and successfully tested in December 2018.

DAC technology is protected by two patents of Ukraine and EU patent. Application is filed for the PCT procedure.
