Piszą że wykorzystują tylko powietrze jako czynnik chłodniczy i nie oddają ciepła lecz zamieniają tę energię na elektryczną. Opis w FAQ dość krótki - ma to szansę działać z sensowną sprawnością, czy to raczej jakiś eko-bełkot marketingowy? Co na to termodynamika?
We have developed a fundamentally new cooling technology. The essence of
dynamic air cooling technology is the direct transformation of warm air into cold
air through the use of gas-dynamic effects. The technology is based on a mixed
universal cycle developed by the authors. The cycle combines two gas-dynamic
and two thermodynamic processes:
adiabatic and isentropic air compression in the compressor;
adiabatic and isentropic expansion, cooling and acceleration of air in the
working element;
isothermal reduction of the kinetic energy of the airflow in the air turbine;
isobaric heating of air when removing heat from the cooled volume of the
refrigerating chamber.
Compared with the traditional vapor compression technology:
DAC uses air instead of hydrofluorocarbons to transfer energy, eliminating
this source of pollution.
It generates no thermal emissions - in all cooling applications, energy is
removed from an air that is being cooled. In traditional cooling units, this
energy has then wasted the heat is disseminated into the atmosphere
further boosting global warming. In DAC, the energy extracted from the
cooled air is not emitted as heat into the atmosphere – instead, it is turned
into electricity.
This electricity is used to contribute towards powering up our units, hence
it is 30% more energy efficient compared with traditional compression
AC/refrigeration system. This means that DAC is much cheaper to run.
Due to much simpler design and smaller size, the manufacturing costs of
our devices are 30% lower.
