Solar Adsorption Cooling: A Case Study on the Climatic Condition of Dhaka

An analytical investigation has been conducted on the performance of an adsorption chiller driven by solar collector panel for the climatic condition of Dhaka. A set of mathematical model and simulation technique are exploited to investigate the system performances of solar driven basic adsorption chiller with silica gel-water as adsorbent/adsorbate pair. For base run condition, at least 13 collectors (each of area 2.415 2 m ) are essential to achieve the required heat source temperature (around 85° C) to provide 10 kW cooling capacity. It is seen that the chiller provide 10kw cooling capacity at noon, while, the system provides solar COP around 0.35. It is also observed that the collector size can be reduced by optimizing cycle time and chilled water outlet temperature can be controlled by setting an appropriate chilled water flow rate.
