The process of indirect evaporative cooling of air is well known, where air or water approaching the wet bulb temperature of outside air. But for the first time in 1976, in the former USSR, (patents SU No 571669; 979796 and etc.) Valeriy Maisotsenko disclosed a configuration wherein a main stream of air is passed along a dry duct, simultaneously passing an auxiliary air stream counter currently along a moist duct which is in heat-exchange relation with the dry duct. The auxiliary stream is obtained by subdividing the total stream into main and auxiliary streams. It gives opportunity to get cold air below the wet bulb and approaching the dew point temperature of outside air. This configuration is further developed and significantly improved by Maisotsenko in the USA (US Patents No 4,350,570; 4,842,052; 4,971,245; 4,976,113; 4,977,753; 5,453,223; 6,497,107; 6,581,402; 6,705,096; 6,776,001; 6,779,351;6,854,278; 6,948,558; 7,007,453; 7,197,887; 7,228,699; 8,613,839; 9,982,907), wherein the wet and dry ducts are divided into 2 separate sections which allows for pre-cooling of the dry air-streams prior to their entry into the wet duct thereby resulting in enhanced cooling efficiency.
Unique Selling Point (USP):
M-Cycle’s cooling capacity increases (not decreases!) when the temperature (T) of the fluid (air or water) being cooled increases. These unique properties make the M-Cycle ideal for many evaporative cooling applications, where high T of incoming air or water transfers for additional cooling capacity.
Delivers cool air at moderate CFM
High volume of moist air exhaust
Low power consumption
Constant low volume bleed-off
Secondary/working air moisture (water) can be regenerated for circular use
As proven by the U.S. National Renewable Energy Lab (NREL) M-Cycle Air Conditioners are 10 times more efficient than traditional systems.
M-Cycle technology four claims:
Energy efficient & low electricity consumption
CFC-free cooling & zero refrigerant GWP and Ozone Depleting Potential
Water savings,
Competitive initial cost
Another innovation is inorganic and mineral material with huge hydrophilic and absorption capacity and enormous evaporation to surface ratio; it transmits water via cellular structure with plenty of pores (cheap and simple) and prevents bacteria spread.
Evaporative material features:
Bio-resistant stable compound
Intense evaporation effect
Advanced capillary effect
Eco-friendly and fully biodegradable
