Thermal behavior of solar powered LiBr-H2O absorption chiller in tropical climate

Thermal behavior of solar powered LiBr-H2O absorption chiller studied under static and dynamic heat input. Performance of the chiller investigated for the tropical climate conditions of Singapore as dynamic heat input. The absorption chiller calibrated prior to physical simulations by comparing standard performance curves of heating capacity and cooling capacity provided by the manufacturer. The performance of calibrated absorption chiller investigated under varying inlet temperatures and mass flow rates of hot water, chilled water and cooling water. It observed that at same inlet temperatures of hot water and chilled water, the heat capacity decreases with the increase in cooling water inlet temperature. It observed that at same inlet temperatures of cooling water and chilled water, the heat capacity increases as the hot water inlet temperature increases. It also observed that at same inlet temperatures of hot and cooling water, heat capacity and cooling capacity increases with chilled water temperature. The performance of the absorption chiller under any given mass flow rates and inlet temperatures of hot water, chilled water and cooling water, performance maps are drawn using characteristic equation. The performance of calibrated absorption chiller further investigated under variable heat input profile by considering the tropical climate conditions of Singapore. This physical simulation setup of absorption chiller could use for any climate conditions.
