Abstract
Applicability of a Solar Adsorption Cooling Machine in Semiarid Regions: Proposal of Supplementary Cooler Using Earth-Water Heat Exchanger
Highlights
Up to now air conditioning and domestic cooling systems in Algeria mainly operate in the traditional way, which needs an important expenditure of electrical energy
We proposed the replacement of the dry cooling tower (DCT) used in the main system with a supplementary water cooling system based on shallow geothermal energy by using earth-water heat exchanger (EWHE)
In an attempt to solve this problem; the present paper suggests the exploitation of the shallow geothermal energy by using an earth-water heat exchanger EWHE as a cooler to replace the DCT when the ambient temperature exceeds its operating limits
Summary
Up to now air conditioning and domestic cooling systems in Algeria mainly operate in the traditional way, which needs an important expenditure of electrical energy. The environmental problems have given a renewed interest to another system (field) called sorption chillers (adsorption and absorption) These alternatives machines become increasingly attractive because the fluids used, in these systems, are benign to the environment whatsoever ammonia, water or alcohols ... In an attempt to solve this problem; the present paper suggests the exploitation of the shallow geothermal energy by using an earth-water heat exchanger EWHE as a cooler to replace the DCT when the ambient temperature exceeds its operating limits. For that we have designed the appropriate EWHE to the region of Biskra to replace a DCT found in the literature
