Characterization of Ammonia–Water Absorption Chiller and Application

International Journal of Air-Conditioning and Refrigeration, 2018
Ammonia-absorption refrigeration units (AARUS) can supply subfreezing refrigeration for many industrial applications. Such units are usually driven by waste heat or renewable energy at relatively low temperatures. The performance of the chiller is highly dependent on the temperatures of the driving heat, the chilling load, and the cooling water.
