Desert Cooler
Thermal comfort diagram Temp. in °C Comfort zone (with air circulation) Relative Humidity in %
PROBLEM How can we reduce the amount of water consumed by the desert cooler?
Peltier Effect
Dry air out
Table 1: Table showing the energy consumed by two different cooling system in 12 months in a 150 m² building Cooling System Energy consumption [k. Wh] 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 [k. Wh] 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 (150 m 2) Cooling System Cost [US dollars] Air Conditioning 3, 500 – 4, 000 Desert Cooler 600 – 1, 000
? Advantages Disadvantages Save energy No 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.
