Abstract:
Adrar is a city in the Sahara desert, in southern Algeria known for its hot and dry
climate, where a huge amount of energy is used for air conditioning. The aim of this research
is to simulate a single effect lithium bromide–water absorption chiller coupled to a double
glazed flat plate collector to supply the cooling loads for a house of 200m2 in Adrar. The
thermal energy is stored in an insulated thermal storage tank. The system was designed to
cover a cooling load of 10.39KW for design day of July. Thermodynamic model was
established to simulate the absorption cycle. The results have shown that the collector mass
flow rate has a negligible effect on the minimum required collector area, but it has a
significant effect on the optimum capacity of the storage tank. The minimum required
collector area was about 65.3 m2, which could supply the cooling loads for the sunshine
hours of the design day for July. The operation of the system has also been considered after
sunset by saving solar energy
