Thermodynamic aspects of selecting an economical domestic cooling system for desert areas
- Technion-Israel Inst. of Technology, Haifa (Israel). Dept. of Civil Engineering
Arid climates such as the one prevailing in the town of Eilath, Israel, are typified by dry and hot summers, a combination best suited for evaporative cooling. Consequently, many residences are equipped with desert coolers. Recently, however, some residents have resorted to air conditioners. This paper considers the thermodynamic aspects of selecting an economical domestic cooling system for an and region. It also discusses the advantages and drawbacks of using the systems and the consequences of possible improvements of each system. The thermodynamic perspective brings out the thermodynamic principle utilized by each system in cooling an apartment. The economic evaluation is based on life-cycle costing (LCC), covering the purchase, installation, operation, and maintenance of the two systems. The economic model most conveniently accommodates small energy consuming systems in buildings. The analysis also allows for the strong interrelation between the economic and thermodynamic aspects, such as dependence of the operating cost on the surrounding climatic conditions as well as on the selected indoor thermal conditions (temperature and humidity).
