The Problem 2

The Problem 3 3

The Solution Hot air 4

The Solution Hot air Cool air 5

The Solution Hot air Cool air 6

The Solution Hot air Cool air 7

The Solution • The houses are represented by the circles M-cycle • Our system is suitable for 10 houses 8

The Heart of the System. Maisotsenko Cycle Multi-layer device to cool down air 9

The Heart of the System. Maisotsenko Cycle I. Half of the air goes in hot and comes out cooled in the other side I. Hot air Cool air 10

The Heart of the System. Maisotsenko Cycle I. Half of the air goes in hot and comes out cooled in the other side II. Hot air Cool air II. The source of cooling is evaporation in the wet channels 11

The Heart of the System. Maisotsenko Cycle I. Half of the air goes in hot and comes out cooled in the other side III. Hot air Cool air II. The source of cooling is evaporation in the wet channels III. The vapor escapes through the air blown perpendicularly 12

Why is it the Best Solution? For 10 houses: Air Conditioning Desert Cooler M-Cycle 10. 5 k. Wh Energy Consumption 3. 3 k. Wh 0. 6 k. Wh Water Consumption none Cooling Power 30 liters/hour 15 liters/hour 13

Overall Maintenance • Water (15 l/h)- Reduce that by desiccants • Energy consumption • 600 W for the cooling system • 30 W for the water pump Is it sustainable? YES! 14

Costs 15

Solar Panels Cooling is necessary mainly in daytime Enough for the 650 Watts We need 3 less efficient solar panels 16

Future plans • Standard air flow • Using air ring • In order to increase efficiency 17
