Table 1: Table showing the energy consumed by two different cooling system in 12 months in a 150 m² building
Cooling System Energy consumption[kWh]
Air Conditioning 6,000
Desert Cooler 1,500
Table 2: Table showing the volume of water used for two evaporative cooling systems per hour.
Cooling System Water Consumption[L/hr]
Regular desert cooler 26.5 - 40
Our design (10 plates) 5 to 10 liters less
Table 3: Table showing the energy consumption of pletier system as compared to regular AC system
Cooling System Energy Consumption[kWh]
Regular air conditioning* 6,000
Our design (10 plates)** 1,200
* Using electrical energy**Using solar energy
Table 4: Table showing the cost of implementation of two different cooling systems for a fully conditioned houses (150m2)
Cooling System Cost [US dollars]
Air Conditioning 3,500 – 4,000
Desert Cooler 600 – 1,000
Advantages Disadvantages
Save energyNo user-driven
regulation
Save water Maintenance
?Heat lost from the peltier system?
What is the rate of the condensation of water?
To what extent can the water be re-circulated?
CONCLUSION
Ventilation cannot be separated from conditioning
Air conditioning accounts for high power consumption and, therefore, money spending
Energy efficiency can be achieved by reducing AC usage
Desert coolers provide with an alternative to such systems
Water loss issue associated to desert coolers can be adressed by platier thermoelectric technology
However, further research is requeried on the subject.
