The analysis of scientific literature shows that the actual efficiency of the adsorption cooling device has not been properly examined. This article presents experimental study on energy efficiency of the adsorption cooling device (max capacity 8 kW) produced at the Laboratory of Building Energy and Microclimate Systems of Vilnius Gediminas Technical University. The study has focused on the measurement of the actual temperatures and flow rate of a heating source, chilled water, a supply of cooled water to the chiller, electricity consumption for circulation pumps and chiller fans. The article presents collected statistical data and shows the dependency of chilled water and heat source temperatures evaluating the coefficients of performance (COP) and electrical efficiency (EER). The received results show higher electrical efficiency of the examined device than that of a conventional compressor system.
