This paper describes the development and investigation of three single-effect hot-water driven, solar thermal powered diffusion absorption cooling machines (DACM) each with a design cooling capacity of 2.5 kW. The first DACM prototype showed that the values of COP ranged from 0.10 to 0.20, and the evaporator cooling capacity could reach 1.5 kW. However, the auxiliary gas circulation of the first prototype was not high enough, leading to fast saturation of evaporated ammonia. The second compacted prototype showed stable and continuous temperature and pressure levels. The reached COPs were between 0.2 and 0.45 and the continuous cooling performance was between 1.0 kW and 1.6 kW. A third prototype with marketable dimensions was set up in October 2005. The results showed cooling capacities between 0.7 kW and 3.0 kW. The reached COPs are between 0.12 and 0.38.
W pracy przedstawiono model oraz badania 3 kolejnych prototypów chłodziarki absorpcyjnej wykorzystującej energię słoneczną. Urządzenie posiada moc chłodzenia równą 2,5 kW. Opracowano model w warunkach pracy ustalonej chłodziarki, który wykazuje dobrą zgodność z wynikami badań.
