Résumé

The paper investigates the development and testing of single-stage solar or waste energy heated ammonia/water diffusion-absorption cooling machines (DACM). The designed cooling capacity of the cooling machine is 2.5 kW at evaporator temperatures between -10°C and 15°C with indirect heating through commercial vacuum tube collectors. the indirectly heated, solar powered generator (bubble pulp) represents the main new feature of this cooling machine. Two DACM pilot plants were built, run and data acquisition was conducted under laboratory conditions as well as simulated field conditions for vacuum tube collectors. The pilot plants were gradually analyzed and stepwise improved. The second pilot plant now reaches a maximum cooling performance of 2 kW and a COP of 0.45 (COP, ratio of cooling output to driving heat input).
