Original abstract
The one-stage experimental absorption chiller with exactly same design of desorber-condenser and absorberevaporator was build up at the Brno University of Technology in 2008. This experimental absorption unit operates with LiBr H2O working pair. Design of the unit keeps two-cylinder conception, which is common for large-scale absorption units. Heat transfer between the working fluid and the heating/cooling water is realized with utilizing of falling film cooper pipe registers. Cooling capacity of the absorption chiller was designed 6 kW on temperature level 9 C. The contribution introduces the design of the 1 stage experimental absorption unit, building, operation experiences and results of carried out measurements. Measurement was focused on assessment of heat transfer on falling film tube bundles and entire COP evaluation. Four independent pumps enable test the influence of flow rate change in different loops of absorption unit.
