“…Citherlet et al [2] and Lu et al [5] used a dry cooling tower DCT which uses the ambient air as a cooling fluid (Fig 2.), Table. 1 shows the main characteristics of the cooling tower used by Citherlet et al However, the operating limits of this solution don't exceed 33-35°C [2], which forces the use of sprays to improve the yield. These sprays consume a lot of water, which is rare in these regions, in addition to the need to provide pumps to ensure the flow of spray water.…”

This paper interests to the applicability of the solar adsorption air refreshment systems in the semiarid region of Biskra (Algeria) and the water cooling system was investigated. 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). The supplementary EWHE operates just when the ambient temperature exceeds the operating limits of the DCT. Thus, we have modeled and sized the EWHE by FORTRAN programming code. After the code validation, we have designed the appropriate EWHE to the region keeping the same pressure drop and respecting all the functioning conditions of an experimental SACM found in the literature. Results are very significant and showed that the geothermal solution can effectively replace the DCT and presents an important reduced cost compared with other solutions.

“…The degree of adsorption of gases using zeolites for capturing carbon dioxide from flue gases for low parameters of adsorption process was investigated by (Wawrzyńczak and Nowak, 2009). A pair of activated carbonwater has been examined by (Lu et al, 2013a;Tso et al, 2012), and a pair of activated carbonmethanol has been examined by (Schicktanz et al, 2012), using other refrigerants having little effect on the greenhouse effect (Jribi et al, 2013), and selective water sorbents . A silica gelwater pair has been studied by (Lu et al, 2013b;Rezk et al, 2012).…”

This paper presents the possibility of reducing the demand for nonrenewable primary energy for buildings using a new conceptual adsorption system of cooling and heating supplied by solar energy. Moreover, the aim of this study is to shorten the payback time of investment in the standard adsorption cooling system through its integration with the heating system. Research has been carried out for an energy-efficient medium-sized single-family building with a floor area of 140 m 2 and a heat load of 4.2 kW and cold load of 4.41 kW. It has been shown that the use of an adsorption system of cooling and heating supplied by solar energy decreased the demand for nonrenewable primary energy by about 66% compared to the standard building that meets the current requirements.
