Experimental Investigation on the Dynamic Performance of a Thermally-Driven Adsorption Chiller Integrated with a Gas Boiler
Abstract
The present study investigates the dynamic performance of a state-of-the-art adsorption chiller to provide useful cooling for a residential and a tertiary building. The equipment was tested at a hardware-in-the-loop configuration in a laboratory setting under the dynamic loads of two simulated building models at two climatic zones in Spain. The adsorption chiller was connected to a hot tank of 760 L volume used to store the heat from an emulated solar collector array. In addition, a gas boiler was used as an auxiliary source of heat to the storage tank. Summertime dynamic experiments of 24 hours were performed at the two building and climate scenarios. The efficiency of the system was analysed in terms of coefficient of performance, coverage of cooling demand and primary energy savings with respect to a reference system.
